1 Introduction
This document provides the technical documentation for the Sustainable Consumption and
Production Hotspots Analysis Tool (SCP-HAT) The SCP-HAT allows for analysing direct as well
as indirect ie trade-related impacts brought about by production and consumption activities
of national economies It is therefore able to identify hotspots related to domestic pressures and
impacts (production or territorial perspective) but also impacts occurring along the supply chains
of goods and services for final consumption in a given country The SCP-HAT provides the
possibility of analysing the performance of a large number of countries with regard to specific
environmental pressures and impacts These analyses can be conducted at national as well as
sectoral level Thereby the tool allows identifying the hotspot areas of unsustainable production
and consumption and based on this analysis supports the setting of priorities in national SCP
and climate policies for investment regulation and planning
The SCP-HAT is a web-based tool at the state of the art of web design It consists of three main
modules Module 1 ldquoCountry Profilerdquo provides the key information regarding the countryrsquos
environmental performance in the context of the most relevant SCP-related policy questions
The target users are policy makers NGOs and the general public Module 2 ldquoSCP Hotspotsrdquo
contains a wide range of SCP indicators to analyse hotspots of unsustainable consumption and
production at country and sector levels This module supports policy advisors and researchers
with expertise by means of detailed information Finally module 3 ldquoNational Data Systemrdquo
provides technical experts such as statisticians the option of inserting national data to receive
more tailored results and carry out crosschecks against the default data as contained in the
underlying model
2 Method description
Technical foundations
In its basic conception SCP-HAT is based upon an Environmentally-Extended Multi-Regional
Input-Output (EE-MRIO) model coupled with Life Cycle Assessment (LCA) for environmental
impact assessment EE-MRIO is an analytical tool supported by the UN System of Environmental-
Economic Accounting (UN-SEEA United Nations 2014) to attribute environmental pressures
and impacts to final demand categories (European Commission et al 2017) EE-MRIO adopts a
top-down approach where supply chain-wide (so-called ldquoindirectrdquo) environmental pressures and
impacts are accounted for at the macro level for broad product groups or industries This is done
by allocating domestic data on pressures (eg material extraction) and impacts (eg
deforestation) expressed in physical units (eg kg also called lsquosatellite accountsrsquo) to monetary
data on transactions among economic sectors and final consumers of different countries Hence
each monetary flow is associated with a physical equivalent (mathematical details in Annex I)
By that means double counting is avoided as the specific supply chains be they national or
international can be clearly identified form their start at resource extraction until the point of
final demand
This approach allows tracing all the pressures and impacts occurring at the different stages of even very complex supply chains and allocating them to the country of final consumption or sectoral production Hence domestic pressures (national environment) are linked to foreign consumption (countries A to F in
Figure 1Figure 1) and foreign pressures to domestic consumption This allows to analyse both
the domestic situation (ldquodomestic productionrdquo) with regard to prevailing pressures and impacts
and the role a country plays as global consumer (ldquoconsumption footprintrdquo) where the focus is
set on pressures and impacts occurring along the supply chains of consumed products
Figure 1 The basic concept of SCP-HAT
This type of analysis is used to identify hotspots of sustainable consumption and production and
opportunities for action (1) pressure or impact categories where immediate action is needed on
the national level and (2) sectors or consumption areas where the pressures or impacts caused
directly or indirectly are specifically high and action is required
In general the consumption footprint of a country is calculated by adding the pressures and
impacts related to imports to those occurring domestically and subtracting those related to the
exports It is important to note the differences between approaches based upon EE-MRIO and
those using coefficients to estimate the indirect trade flows of pressures and impacts and the
consumption footprint of a country
- Coefficient approaches calculate the total environmental pressures or impacts associated
with final consumption by accounting for physical in- and out-flows of a country and
considering the environmental intensity of the traded commodities along the whole
production chain They apply intensity coefficients ndash or ldquocradle-to-productrdquo coefficients ndash
to the specific traded products and activities Here the consumption footprint of a country
is calculated by adding the pressures and impacts related to all imports to those occurring
domestically and subtracting those related to all the exports
Coefficient approaches apply the concept of ldquoapparent consumptionrdquo ie they cannot
specify whether a certain environmental pressure or impact is associated with
intermediate production or consumed by the final consumer Accordingly trade balances
are calculated in gross terms ie considering both intermediate and final trade products
(see above) Though conceptually feasible in practice it is not possible to separate eg
private consumption from government consumption Finally often so-called ldquotruncation
errorsrdquo are produced as the indirect flows are not traced along the entire industrial supply
chains The most important advantage of coefficient-based approaches is the high level of
detail and transparency which can be applied in footprint-oriented indicator calculations
- As explained above input-output analysis allows tracing monetary flows and embodied
environmental factors from its origin (eg raw material extraction) to the final consumption
of the respective products The so-called ldquoLeontief inverserdquo a matrix generated from an
input-output table (see Annex I) shows for each commodity or industry represented in
the model all direct and indirect inputs and related environmental pressures and impacts
required along the complete supply chain Doing the calculation for all product groups all
environmental pressures and impacts needed to satisfy final demand of a country can be
quantified
A major advantage of input-output based approaches is that input-output tables
disaggregate a large number of different product groups and industries as well as final
demand categories (eg private consumption government consumption investments
etc) They allow calculating the footprints for all products and all sectors also those with
very complex supply chains and thus avoid truncation errors (see above) Finally the
countries of origin of a countryrsquos consumption footprint can be identified as well as the
countries of destination of the domestic environmental pressures and impacts
Consequently in contrast to coefficient-based approaches analyses of indirect trade flows
are done from the perspective of linking source countries with final demand in the
destination countries Hence trade analyses in Module 1 and 2 of SCP-HAT have to be
understood before this background import flows into a country of interest will only include
those pressures and impacts occurring abroad which contribute to the countryrsquos final
demand Export flows incorporate only the pressures and impacts which occur
domestically and contribute to final demand abroad Consequently flows which ldquopass
throughrdquo the country via imports and re-exports are not accounted for
When comparing results for a country of interest which stem from MRIO-based and
coefficient-based approaches conceptually the numbers for the consumption footprint can
be directly compared while those for trade flows cannot
EE-MRIO is complemented by impact assessment for the calculation of certain environmental
impact variables (using Life Cycle Impact Assessment (LCIA) characterization factors) While
environmental accounts used in EE-MRIO provide data on domestic resource use in the countries
around the world LCIA ldquotranslatesrdquo these amounts into environmental impacts such as
biodiversity loss from land use or resource depletion related to raw material use This
methodological step is realised in accordance with the LCIA guidelines set by the United Nations
Environment Programme (UNEP 2016)
Pressure and impact categories
Ideally the SCP-HAT tool would cover all indicators included in the 10-year framework of
programmes on sustainable consumption and production patterns (10YFP) Evaluation and
Monitoring Framework1 ie material use waste water use energy use GHG emissions air soil
and water pollutants biodiversity conservation and land use and human well-being indicators
related to gender decent work and health However for the development of the 2018 version
of the tool a first selection of highly relevant pressure and impact categories are implemented
Environmental pressures
o Raw material use
o Land use (occupation only)
o Emissions of greenhouse gases
o Emissions of particulate matter and precursors
Environmental impacts
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
The selection of a first set of pressures and impacts was guided by a set of criteria
Readiness of data availability
Relevance for SCP policy questions
Interrelatedness of pressures and impacts
Widely accepted impact characterization factors
Moreover the focus was set on an extensive coverage of related issues to be covered indirectly
with the selected domains For instance material flows include most energy carriers (and to a
large extend also cover energy) and allow for proxies for waste GHG emissions also have a large
overlap with energy use (more comprehensively when compared to material flows) They relate
1 httpwwwoneplanetnetworkorgresource10yfp-indicators-success
to two important policy areas of resource efficiency and climate mitigation identified as priorities
by many governments including the G7 and G20
Further categories to be integrated in future version of the SCP-HAT could include for example
Water use and water scarcity
Primary energy
Land transformation
Mercury emissions
Solid waste
Social life-cycle impacts (hazardous or child labour corruption etc)
Geographical and IndustryProduct coverage
The aim of SCP-HAT is to cover all countries in the world including those with relatively short
history of engaging more actively in policy making around policy areas such as SCP the SDGs
green economy etc The geographical coverage of SCP-HAT is based on the official list of UN
Member States2 but constrained by the country resolution of the databases utilised This choice
does not imply any political judgment All databases utilised in the SCP-HAT have their own
territorial definitions which do not always coincide especially regarding to former colonies
territories with independence partially recognized etc In total the SCP-HAT includes 171 UN
state members for which data are available in all databases There are some lsquospecial casesrsquo
Sudan includes South Sudan from 1990 to 2011 while Ethiopia includes Eritrea from 1990 to
1992 The full list is provided in Annex II The unified sector aggregation applied encompasses
26 economic sectorsproduct categories which is the level of detail of the underlying input-
output model (see below) A complete list can be found in the Annex III
3 Data sources
Multi-Regional Input-Output
There are a number of global input-output models available which allow for comprehensive EE-
MRIO modelling Depending on the political or scientific question to be answered they have their
strengths and weaknesses The input-output core applied in the SCP-HAT is the lsquoEorarsquo database
(Lenzen et al 2013 2012) Its major advantage in comparison to other available MRIO
databases is its geographical coverage of 188 single countries and thus the possibility to perform
nation-specific analysis for almost any country in the world Two Eora version are available the
2 httpwwwunorgenmember-states
Full Eora and the Eora26 The difference between them resides in the sectoral classification The
former uses the original sector disaggregation of the IO-tables as provided by the original source
Here the resolution varies between 26 and a few hundred sectors The latter applies a
harmonised 26sectors disaggregation for all countries For SCP-HAT we apply the Eora26 Even
though Full Eora can be considered more accurate using Eora26 avoids possible computational
problems since memory needs and server space would be significantly lower Time series are
available for 1990 to 2015 which is hence also the time span for the SCP-HAT
GHG emissions and Climate Change (Short-Term and Long-Term)
The UNEP LCI guidance for LCIA indicators makes an interim recommendation for considering
two impact categories for climate change short-term related to the rate of temperature change
and long-term related to the long-term temperature rise (UNEP 2016) The indicators
recommended for short-term and long-term respectively are Global Warming Potential 100
(GWP100) and Global Temperature change Potential (GTP100) at 100 years horizon The
corresponding characterization factors provided by UNEP are applied to GHG emissions data
with impact factors for 24 separate emissions including differentiation of fossil- and biogenic
methane (Full list of GWP and GTP factors in Annex IV) Near-term climate forcing gases are
excluded as the UNEP LCI guidance recommends those for sensitivity analysis only
Two sources are employed for compiling the SCP-HATrsquos GHG emissions input data The main
dataset was the PRIMAP-hist (PRIMAP ndash Potsdam Realtime Integrated Model for Probabilistic
Assessment of Emissions Paths) developed by the Potsdam Institute for Climate Impact Research
(Guumltschow et al 2019 2016) PRIMAP-hist was selected because of its coverage of long time
series and because it integrates other popular global GHG datasets (eg British Petroleum
Review of World Energy (BP 2014) Carbon Dioxide Information Analysis Center fossil fuel and
industrial CO2 emissions dataset (Boden et al 2015) the EDGAR dataset (Janssens-Maenhout
et al 2019) It includes emissions for the main Kyoto greenhouse gases carbon dioxide (CO2)
methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons
(PFCs)sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3) for the period of 1850 to 2016
The country detail is high including almost all countries considered in the SCP-HAT
The PRIMAP-hist sector categorization is based on the main Intergovernmental Panel on Climate
Change (IPCC) 2006 categories It has been analysed in the literature that too poor sector
resolution in the environmental extension of EE-MRIO models can cause aggregation errors
(Steen-Olsen et al 2014 Su et al 2010) and inclusion of external data for further
disaggregation is recommended (Lenzen 2011) To prevent this aggregation bias the PRIMAP-
hist data is further disaggregated using GHG emissions shares from the EDGAR database which
is maintained by the European Commission Joint Research Centre (JRC) and the Netherlands
Environmental Assessment Agency (PBL) (Janssens-Maenhout et al 2019 Olivier and Janssens-
Maenhout 2012) The shares of the different IPCC categories contributing to the total as reported
by EDGAR were applied to the totals published by PRIMAP-hist and used for SCP-HAT Three
specific EDGAR datasets are utilized the Edgar version 432 the EDGAR version 42 Fast Track
(FT) 2010 and the EDGAR version 42 For CO2 CH4 and N2O and the whole period Edgar
version 432 was used For SF6 the Edgar version 42 was used for the period 1990-1999 and
the Edgar version 42 FT for the period 2000-2010 Edgar shares from version 42 were adjusted
using the same approach as FAOSTAT for compiling their ldquoEmissions by sectorrdquo3 dataset For
HFCs and PFCs the EDGAR version 42 FT 2010 was used and shares from 2000 were assumed
as being equal for the period 1990-1999 For HFCs PFCs and SF6 shares for 2010 from Edgar
FT 2010 were applied for the disaggregation of the years 2011 to 2015 After the disaggregation
of the PRIMAP-hist data the IPCC 2006 categories were allocated to one or more sectors of the
SCP-HAT (ie Eora 26 sectors) The IPCC 2006 sector classification in the SCP-HAT and the
correspondence to the SCP-HAT sectors is provided in Annex V For those categories allocated
to more than one sector the emissions were disaggregated according to the relationship of the
total output of the sectors
Lastly emissions from road transportation from industries and households are recorded together
in PRIMAP-hits and EDGAR which need to be disaggregated for a finer analysis in the SCP-HAT
This was done applying the shares of different industries and households in the overall use of
the category lsquoPetroleum Chemical and Non-Metallic Mineral Productsrsquo as provided in Eora
Raw material use and mineral and fossil resource scarcity
For physical data for raw material extraction data from UN IRP Global Material Flows Database
(UN IRP 2017) are used It includes 13 aggregated raw material categories compiled following
lsquoeconomy-wide material flow accountingrsquo principles (Eurostat 2013 OECD 2008) for 192
countries including most of the countries of the SCP-HAT A full list of the raw material extraction
categories can be found in Annex VI National material extraction is allocated to the three
extractive sectors contained in the Eora26 sector classification ndash lsquoagriculturersquo lsquofishingrsquo and
lsquomining and quarryingrsquo While such a high aggregation of extractive sectors can result in a
distortion of the overall results (de Koning et al 2015 Pintildeero et al 2014) an improvement by
means for instance of allocating the extractions to intermediate users (Giljum et al 2017
Schaffartzik et al 2013 Wiebe et al 2012) ndash eg iron from mining to the steel industry ndash is
implemented in some cases The resulting allocation is sometimes referred as lsquouse extensionrsquo in
contrast to the most common lsquosupply extensionrsquo (further details in Annex I)
3 See httpwwwfaoorgfaostatendataEM
Raw material extraction for abiotic materials is translated into impacts by using the mineral and
fossil resource scarcity characterization factors from the Dutch National Institute for Public Health
and the Environment (RIVM) (Huijbregts et al 2016) The midpoint indicator (ie focussing on
intermediate stage along the impact pathway) for fossil resource scarcity is defined as the ratio
between the energy content of fossil resource x and the energy content of crude oil The unit of
this indicator is kg oil-equivalent and it simply reflects the energy content compared to a kilogram
of oil The characterization method for mineral resource scarcity is Surplus Ore Potential which
expresses the average extra amount of ore to be produced in the future due to the extraction of
1 kg of a mineral resource x In other words this reflects the decrease in ore grade of remaining
reserves The indicator is expressed relative to copper in units of kg Cu-equivalent The
ldquohierarchistrdquo version of this indicator is applied which means that future production is chosen to
be the ultimate recoverable resource For more details see RIVM (Huijbregts et al 2016) An
unweighted average characterization factor for the group of ldquoOther metalsrdquo was derived using
the 25 materials listed in that category in the Global Material Flows Database The resulting
factor was dominated by caesium which is probably higher than realistic In version 11 the
characterization factor for the group of ldquoOther metalsrdquo was updated by using a global-production-
weighted average (averaged over the years 2012-2014 as data for some metals are only
available after 2012) This resulted in a significant reduction of the factor with the main
contributors being mercury magnesium zirconium and hafnium
Land use and potential species loss from land use
The UNEP LCI guidance for LCIA indicators makes an interim recommendation (see UNEP 2016)
for characterization of biodiversity impacts of land use discerning occupation and
transformation based on the method developed by Chaudhary et al (2015) In this first version
of the SCP-HAT only land occupation is included and modelling of land transformation is left for
future tool developments To allow for the application of the recommended characterization
factors inventory data is required for land occupation (m2a) for six land use classes - Annual
crops Permanent crops Pasture Extensive forestry Intensive forestry Urban Annex VII shows
sector correspondence for the land use categories in the SCP-HAT Land use for crops and
pasture is allocated partly to the agriculture sector and partly to final demand The allocation to
final demand is made based on data on subsistence and low-input crop farming derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) For details on the
allocation methodology see Annex XXI Land use for intensive forestry is allocated to the wood
and paper industry (ie allocation to first intermediate users see Annex I) Land use for
extensive forestry is allocated partly to the wood and paper industry and partly to final demand
based on domestic wood fuel production and consumption statistics For details on the allocation
methodology see Annex XXI
Land use for other industrial activities than agriculture or forestry (eg mining) is not covered
From version v11 onwards built-up land is allocated directly to final demand and estimated
using OECD land use statistics (OECD 2018)
The definition of the two forestry land use classes used for the impact characterization is i)
Intensive Forest forests with extractive use with either even-aged stands and clear-cut
patches or less than three naturally occurring species at plantingseeding and ii) Extensive
Forests forests with extractive use and associated disturbance like hunting and selective
logging where timber extraction is followed by re-growth including at least three naturally
occurring tree species For the latter alternative uses to wood and paper eg recreation
hunting etc are not considered
Land use data for Annual crops Permanent crops and Pasture are gathered from FAOSTATrsquos
databases for the analogous categories arable land permanent crops and permanent meadows
and pastures (Food and Agriculture Organization of the United Nations 2018) Table 1 shows
data sources and model description for Extensive and Intensive Forestry
Following UNEPrsquos recommendations country-level average characterization factors for global
species loss from Chaudhary et al (2015) are used in the SCP-HAT aggregated over five taxa
(mammals reptiles birds amphibians and vascular plants) for each of the six land use
categories The unit of this indicator is PDFyear which stands for the Potentially Disappeared
Fraction of species for the duration of a year Land use impact modelling assumes that once an
activity (land use) stops the system will slowly return to the natural state The indicator
therefore does not reflect full extinction of species but a temporary decline in biodiversity

Air pollution and health impacts
Many emissions contribute to air pollution via a variety of mechanisms SCP-HAT focuses on air
pollution via particulate matter (PM) which is caused by emissions of PM itself as well as by
emissions of NH3 NOx and SO2 which form so-called secondary PM via chemical reactions The
UNEP LCI guidance for LCIA indicators (UNEP 2016) recommends the use of characterization
factors at end-point reflecting damages to human health expressed in Disability-Adjusted Life
Years (DALY) The recommended approach for calculating DALY impact factors is via emission
source archetypes but this could not be implemented at the global highly aggregated scale of
emissions data used in SCP-HAT The tool therefore uses DALY impact factors from RIVM
(Huijbregts et al 2016) which reflect country-averaged DALY impacts per unit of emission for
each of the four substances (PM25 NH3 SO2 NOx) No differentiation is made by emission source
type at this stage A recent set of new effect factors (Fantke et al 2019) is still only available
at country level without additional distinction of emission source type
The emissions data are taken from the EDGAR database (v432) This database covers all
countries and years up to and including 2012 For emissions of primary PM25 fossil and biogenic
sources are distinguished There is no difference in impact (DALYkg emitted) between those
two categories The data are extrapolated to 2013 and 2015 using GHG emissions trends with a
fixed emission ratio based on 2012 data As shown in Crippa et al (2018) emission ratios of air
pollutants to carbon dioxide have steadily decreased since 1970 but have been relatively stable
since around 2010 especially for NOx and SO2 More specifically PM25 fossil NOx and SO2 are
projected using CO2 emissions trends while CH4 and N2O (in CO2 eq) are used for PM25 bio and
NH3 During data processing it was found that this approach is not satisfactory for NH3 emissions
from agriculture and results are of especially high uncertainty for this category Thus future
improvements should prioritize this specific flow
Socio-economic data
The SCP-HAT includes a set of basic socioeconomic data which mainly serves for the estimation
of relative performance indicators of economies and industries eg carbon per unit of economic
output In the following the data sources used are listed
Population The World Bank Group
GDP The World Bank Group
Value added Eora database
Output Eora database
Employment per sector International Labour Organization
Country groups The World Bank Group
Government and private final consumption Eora database
HDI United Nations Development Programme
Country groups The World Bank Group
Employment by sector and gender is compiled from the ILO (International Labour Organization
2018) The dataset on employment by gender and sector includes only 14 sectors
Disaggregation is done using compensation to employees in Eora as proxy (ie it is assumed
same retribution between sectors belonging to an ILO category)
4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

1 Introduction
This document provides the technical documentation for the Sustainable Consumption and
Production Hotspots Analysis Tool (SCP-HAT) The SCP-HAT allows for analysing direct as well
as indirect ie trade-related impacts brought about by production and consumption activities
of national economies It is therefore able to identify hotspots related to domestic pressures and
impacts (production or territorial perspective) but also impacts occurring along the supply chains
of goods and services for final consumption in a given country The SCP-HAT provides the
possibility of analysing the performance of a large number of countries with regard to specific
environmental pressures and impacts These analyses can be conducted at national as well as
sectoral level Thereby the tool allows identifying the hotspot areas of unsustainable production
and consumption and based on this analysis supports the setting of priorities in national SCP
and climate policies for investment regulation and planning
The SCP-HAT is a web-based tool at the state of the art of web design It consists of three main
modules Module 1 ldquoCountry Profilerdquo provides the key information regarding the countryrsquos
environmental performance in the context of the most relevant SCP-related policy questions
The target users are policy makers NGOs and the general public Module 2 ldquoSCP Hotspotsrdquo
contains a wide range of SCP indicators to analyse hotspots of unsustainable consumption and
production at country and sector levels This module supports policy advisors and researchers
with expertise by means of detailed information Finally module 3 ldquoNational Data Systemrdquo
provides technical experts such as statisticians the option of inserting national data to receive
more tailored results and carry out crosschecks against the default data as contained in the
underlying model
2 Method description
Technical foundations
In its basic conception SCP-HAT is based upon an Environmentally-Extended Multi-Regional
Input-Output (EE-MRIO) model coupled with Life Cycle Assessment (LCA) for environmental
impact assessment EE-MRIO is an analytical tool supported by the UN System of Environmental-
Economic Accounting (UN-SEEA United Nations 2014) to attribute environmental pressures
and impacts to final demand categories (European Commission et al 2017) EE-MRIO adopts a
top-down approach where supply chain-wide (so-called ldquoindirectrdquo) environmental pressures and
impacts are accounted for at the macro level for broad product groups or industries This is done
by allocating domestic data on pressures (eg material extraction) and impacts (eg
deforestation) expressed in physical units (eg kg also called lsquosatellite accountsrsquo) to monetary
data on transactions among economic sectors and final consumers of different countries Hence
each monetary flow is associated with a physical equivalent (mathematical details in Annex I)
By that means double counting is avoided as the specific supply chains be they national or
international can be clearly identified form their start at resource extraction until the point of
final demand
This approach allows tracing all the pressures and impacts occurring at the different stages of even very complex supply chains and allocating them to the country of final consumption or sectoral production Hence domestic pressures (national environment) are linked to foreign consumption (countries A to F in
Figure 1Figure 1) and foreign pressures to domestic consumption This allows to analyse both
the domestic situation (ldquodomestic productionrdquo) with regard to prevailing pressures and impacts
and the role a country plays as global consumer (ldquoconsumption footprintrdquo) where the focus is
set on pressures and impacts occurring along the supply chains of consumed products
Figure 1 The basic concept of SCP-HAT
This type of analysis is used to identify hotspots of sustainable consumption and production and
opportunities for action (1) pressure or impact categories where immediate action is needed on
the national level and (2) sectors or consumption areas where the pressures or impacts caused
directly or indirectly are specifically high and action is required
In general the consumption footprint of a country is calculated by adding the pressures and
impacts related to imports to those occurring domestically and subtracting those related to the
exports It is important to note the differences between approaches based upon EE-MRIO and
those using coefficients to estimate the indirect trade flows of pressures and impacts and the
consumption footprint of a country
- Coefficient approaches calculate the total environmental pressures or impacts associated
with final consumption by accounting for physical in- and out-flows of a country and
considering the environmental intensity of the traded commodities along the whole
production chain They apply intensity coefficients ndash or ldquocradle-to-productrdquo coefficients ndash
to the specific traded products and activities Here the consumption footprint of a country
is calculated by adding the pressures and impacts related to all imports to those occurring
domestically and subtracting those related to all the exports
Coefficient approaches apply the concept of ldquoapparent consumptionrdquo ie they cannot
specify whether a certain environmental pressure or impact is associated with
intermediate production or consumed by the final consumer Accordingly trade balances
are calculated in gross terms ie considering both intermediate and final trade products
(see above) Though conceptually feasible in practice it is not possible to separate eg
private consumption from government consumption Finally often so-called ldquotruncation
errorsrdquo are produced as the indirect flows are not traced along the entire industrial supply
chains The most important advantage of coefficient-based approaches is the high level of
detail and transparency which can be applied in footprint-oriented indicator calculations
- As explained above input-output analysis allows tracing monetary flows and embodied
environmental factors from its origin (eg raw material extraction) to the final consumption
of the respective products The so-called ldquoLeontief inverserdquo a matrix generated from an
input-output table (see Annex I) shows for each commodity or industry represented in
the model all direct and indirect inputs and related environmental pressures and impacts
required along the complete supply chain Doing the calculation for all product groups all
environmental pressures and impacts needed to satisfy final demand of a country can be
quantified
A major advantage of input-output based approaches is that input-output tables
disaggregate a large number of different product groups and industries as well as final
demand categories (eg private consumption government consumption investments
etc) They allow calculating the footprints for all products and all sectors also those with
very complex supply chains and thus avoid truncation errors (see above) Finally the
countries of origin of a countryrsquos consumption footprint can be identified as well as the
countries of destination of the domestic environmental pressures and impacts
Consequently in contrast to coefficient-based approaches analyses of indirect trade flows
are done from the perspective of linking source countries with final demand in the
destination countries Hence trade analyses in Module 1 and 2 of SCP-HAT have to be
understood before this background import flows into a country of interest will only include
those pressures and impacts occurring abroad which contribute to the countryrsquos final
demand Export flows incorporate only the pressures and impacts which occur
domestically and contribute to final demand abroad Consequently flows which ldquopass
throughrdquo the country via imports and re-exports are not accounted for
When comparing results for a country of interest which stem from MRIO-based and
coefficient-based approaches conceptually the numbers for the consumption footprint can
be directly compared while those for trade flows cannot
EE-MRIO is complemented by impact assessment for the calculation of certain environmental
impact variables (using Life Cycle Impact Assessment (LCIA) characterization factors) While
environmental accounts used in EE-MRIO provide data on domestic resource use in the countries
around the world LCIA ldquotranslatesrdquo these amounts into environmental impacts such as
biodiversity loss from land use or resource depletion related to raw material use This
methodological step is realised in accordance with the LCIA guidelines set by the United Nations
Environment Programme (UNEP 2016)
Pressure and impact categories
Ideally the SCP-HAT tool would cover all indicators included in the 10-year framework of
programmes on sustainable consumption and production patterns (10YFP) Evaluation and
Monitoring Framework1 ie material use waste water use energy use GHG emissions air soil
and water pollutants biodiversity conservation and land use and human well-being indicators
related to gender decent work and health However for the development of the 2018 version
of the tool a first selection of highly relevant pressure and impact categories are implemented
Environmental pressures
o Raw material use
o Land use (occupation only)
o Emissions of greenhouse gases
o Emissions of particulate matter and precursors
Environmental impacts
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
The selection of a first set of pressures and impacts was guided by a set of criteria
Readiness of data availability
Relevance for SCP policy questions
Interrelatedness of pressures and impacts
Widely accepted impact characterization factors
Moreover the focus was set on an extensive coverage of related issues to be covered indirectly
with the selected domains For instance material flows include most energy carriers (and to a
large extend also cover energy) and allow for proxies for waste GHG emissions also have a large
overlap with energy use (more comprehensively when compared to material flows) They relate
1 httpwwwoneplanetnetworkorgresource10yfp-indicators-success
to two important policy areas of resource efficiency and climate mitigation identified as priorities
by many governments including the G7 and G20
Further categories to be integrated in future version of the SCP-HAT could include for example
Water use and water scarcity
Primary energy
Land transformation
Mercury emissions
Solid waste
Social life-cycle impacts (hazardous or child labour corruption etc)
Geographical and IndustryProduct coverage
The aim of SCP-HAT is to cover all countries in the world including those with relatively short
history of engaging more actively in policy making around policy areas such as SCP the SDGs
green economy etc The geographical coverage of SCP-HAT is based on the official list of UN
Member States2 but constrained by the country resolution of the databases utilised This choice
does not imply any political judgment All databases utilised in the SCP-HAT have their own
territorial definitions which do not always coincide especially regarding to former colonies
territories with independence partially recognized etc In total the SCP-HAT includes 171 UN
state members for which data are available in all databases There are some lsquospecial casesrsquo
Sudan includes South Sudan from 1990 to 2011 while Ethiopia includes Eritrea from 1990 to
1992 The full list is provided in Annex II The unified sector aggregation applied encompasses
26 economic sectorsproduct categories which is the level of detail of the underlying input-
output model (see below) A complete list can be found in the Annex III
3 Data sources
Multi-Regional Input-Output
There are a number of global input-output models available which allow for comprehensive EE-
MRIO modelling Depending on the political or scientific question to be answered they have their
strengths and weaknesses The input-output core applied in the SCP-HAT is the lsquoEorarsquo database
(Lenzen et al 2013 2012) Its major advantage in comparison to other available MRIO
databases is its geographical coverage of 188 single countries and thus the possibility to perform
nation-specific analysis for almost any country in the world Two Eora version are available the
2 httpwwwunorgenmember-states
Full Eora and the Eora26 The difference between them resides in the sectoral classification The
former uses the original sector disaggregation of the IO-tables as provided by the original source
Here the resolution varies between 26 and a few hundred sectors The latter applies a
harmonised 26sectors disaggregation for all countries For SCP-HAT we apply the Eora26 Even
though Full Eora can be considered more accurate using Eora26 avoids possible computational
problems since memory needs and server space would be significantly lower Time series are
available for 1990 to 2015 which is hence also the time span for the SCP-HAT
GHG emissions and Climate Change (Short-Term and Long-Term)
The UNEP LCI guidance for LCIA indicators makes an interim recommendation for considering
two impact categories for climate change short-term related to the rate of temperature change
and long-term related to the long-term temperature rise (UNEP 2016) The indicators
recommended for short-term and long-term respectively are Global Warming Potential 100
(GWP100) and Global Temperature change Potential (GTP100) at 100 years horizon The
corresponding characterization factors provided by UNEP are applied to GHG emissions data
with impact factors for 24 separate emissions including differentiation of fossil- and biogenic
methane (Full list of GWP and GTP factors in Annex IV) Near-term climate forcing gases are
excluded as the UNEP LCI guidance recommends those for sensitivity analysis only
Two sources are employed for compiling the SCP-HATrsquos GHG emissions input data The main
dataset was the PRIMAP-hist (PRIMAP ndash Potsdam Realtime Integrated Model for Probabilistic
Assessment of Emissions Paths) developed by the Potsdam Institute for Climate Impact Research
(Guumltschow et al 2019 2016) PRIMAP-hist was selected because of its coverage of long time
series and because it integrates other popular global GHG datasets (eg British Petroleum
Review of World Energy (BP 2014) Carbon Dioxide Information Analysis Center fossil fuel and
industrial CO2 emissions dataset (Boden et al 2015) the EDGAR dataset (Janssens-Maenhout
et al 2019) It includes emissions for the main Kyoto greenhouse gases carbon dioxide (CO2)
methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons
(PFCs)sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3) for the period of 1850 to 2016
The country detail is high including almost all countries considered in the SCP-HAT
The PRIMAP-hist sector categorization is based on the main Intergovernmental Panel on Climate
Change (IPCC) 2006 categories It has been analysed in the literature that too poor sector
resolution in the environmental extension of EE-MRIO models can cause aggregation errors
(Steen-Olsen et al 2014 Su et al 2010) and inclusion of external data for further
disaggregation is recommended (Lenzen 2011) To prevent this aggregation bias the PRIMAP-
hist data is further disaggregated using GHG emissions shares from the EDGAR database which
is maintained by the European Commission Joint Research Centre (JRC) and the Netherlands
Environmental Assessment Agency (PBL) (Janssens-Maenhout et al 2019 Olivier and Janssens-
Maenhout 2012) The shares of the different IPCC categories contributing to the total as reported
by EDGAR were applied to the totals published by PRIMAP-hist and used for SCP-HAT Three
specific EDGAR datasets are utilized the Edgar version 432 the EDGAR version 42 Fast Track
(FT) 2010 and the EDGAR version 42 For CO2 CH4 and N2O and the whole period Edgar
version 432 was used For SF6 the Edgar version 42 was used for the period 1990-1999 and
the Edgar version 42 FT for the period 2000-2010 Edgar shares from version 42 were adjusted
using the same approach as FAOSTAT for compiling their ldquoEmissions by sectorrdquo3 dataset For
HFCs and PFCs the EDGAR version 42 FT 2010 was used and shares from 2000 were assumed
as being equal for the period 1990-1999 For HFCs PFCs and SF6 shares for 2010 from Edgar
FT 2010 were applied for the disaggregation of the years 2011 to 2015 After the disaggregation
of the PRIMAP-hist data the IPCC 2006 categories were allocated to one or more sectors of the
SCP-HAT (ie Eora 26 sectors) The IPCC 2006 sector classification in the SCP-HAT and the
correspondence to the SCP-HAT sectors is provided in Annex V For those categories allocated
to more than one sector the emissions were disaggregated according to the relationship of the
total output of the sectors
Lastly emissions from road transportation from industries and households are recorded together
in PRIMAP-hits and EDGAR which need to be disaggregated for a finer analysis in the SCP-HAT
This was done applying the shares of different industries and households in the overall use of
the category lsquoPetroleum Chemical and Non-Metallic Mineral Productsrsquo as provided in Eora
Raw material use and mineral and fossil resource scarcity
For physical data for raw material extraction data from UN IRP Global Material Flows Database
(UN IRP 2017) are used It includes 13 aggregated raw material categories compiled following
lsquoeconomy-wide material flow accountingrsquo principles (Eurostat 2013 OECD 2008) for 192
countries including most of the countries of the SCP-HAT A full list of the raw material extraction
categories can be found in Annex VI National material extraction is allocated to the three
extractive sectors contained in the Eora26 sector classification ndash lsquoagriculturersquo lsquofishingrsquo and
lsquomining and quarryingrsquo While such a high aggregation of extractive sectors can result in a
distortion of the overall results (de Koning et al 2015 Pintildeero et al 2014) an improvement by
means for instance of allocating the extractions to intermediate users (Giljum et al 2017
Schaffartzik et al 2013 Wiebe et al 2012) ndash eg iron from mining to the steel industry ndash is
implemented in some cases The resulting allocation is sometimes referred as lsquouse extensionrsquo in
contrast to the most common lsquosupply extensionrsquo (further details in Annex I)
3 See httpwwwfaoorgfaostatendataEM
Raw material extraction for abiotic materials is translated into impacts by using the mineral and
fossil resource scarcity characterization factors from the Dutch National Institute for Public Health
and the Environment (RIVM) (Huijbregts et al 2016) The midpoint indicator (ie focussing on
intermediate stage along the impact pathway) for fossil resource scarcity is defined as the ratio
between the energy content of fossil resource x and the energy content of crude oil The unit of
this indicator is kg oil-equivalent and it simply reflects the energy content compared to a kilogram
of oil The characterization method for mineral resource scarcity is Surplus Ore Potential which
expresses the average extra amount of ore to be produced in the future due to the extraction of
1 kg of a mineral resource x In other words this reflects the decrease in ore grade of remaining
reserves The indicator is expressed relative to copper in units of kg Cu-equivalent The
ldquohierarchistrdquo version of this indicator is applied which means that future production is chosen to
be the ultimate recoverable resource For more details see RIVM (Huijbregts et al 2016) An
unweighted average characterization factor for the group of ldquoOther metalsrdquo was derived using
the 25 materials listed in that category in the Global Material Flows Database The resulting
factor was dominated by caesium which is probably higher than realistic In version 11 the
characterization factor for the group of ldquoOther metalsrdquo was updated by using a global-production-
weighted average (averaged over the years 2012-2014 as data for some metals are only
available after 2012) This resulted in a significant reduction of the factor with the main
contributors being mercury magnesium zirconium and hafnium
Land use and potential species loss from land use
The UNEP LCI guidance for LCIA indicators makes an interim recommendation (see UNEP 2016)
for characterization of biodiversity impacts of land use discerning occupation and
transformation based on the method developed by Chaudhary et al (2015) In this first version
of the SCP-HAT only land occupation is included and modelling of land transformation is left for
future tool developments To allow for the application of the recommended characterization
factors inventory data is required for land occupation (m2a) for six land use classes - Annual
crops Permanent crops Pasture Extensive forestry Intensive forestry Urban Annex VII shows
sector correspondence for the land use categories in the SCP-HAT Land use for crops and
pasture is allocated partly to the agriculture sector and partly to final demand The allocation to
final demand is made based on data on subsistence and low-input crop farming derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) For details on the
allocation methodology see Annex XXI Land use for intensive forestry is allocated to the wood
and paper industry (ie allocation to first intermediate users see Annex I) Land use for
extensive forestry is allocated partly to the wood and paper industry and partly to final demand
based on domestic wood fuel production and consumption statistics For details on the allocation
methodology see Annex XXI
Land use for other industrial activities than agriculture or forestry (eg mining) is not covered
From version v11 onwards built-up land is allocated directly to final demand and estimated
using OECD land use statistics (OECD 2018)
The definition of the two forestry land use classes used for the impact characterization is i)
Intensive Forest forests with extractive use with either even-aged stands and clear-cut
patches or less than three naturally occurring species at plantingseeding and ii) Extensive
Forests forests with extractive use and associated disturbance like hunting and selective
logging where timber extraction is followed by re-growth including at least three naturally
occurring tree species For the latter alternative uses to wood and paper eg recreation
hunting etc are not considered
Land use data for Annual crops Permanent crops and Pasture are gathered from FAOSTATrsquos
databases for the analogous categories arable land permanent crops and permanent meadows
and pastures (Food and Agriculture Organization of the United Nations 2018) Table 1 shows
data sources and model description for Extensive and Intensive Forestry
Following UNEPrsquos recommendations country-level average characterization factors for global
species loss from Chaudhary et al (2015) are used in the SCP-HAT aggregated over five taxa
(mammals reptiles birds amphibians and vascular plants) for each of the six land use
categories The unit of this indicator is PDFyear which stands for the Potentially Disappeared
Fraction of species for the duration of a year Land use impact modelling assumes that once an
activity (land use) stops the system will slowly return to the natural state The indicator
therefore does not reflect full extinction of species but a temporary decline in biodiversity

Air pollution and health impacts
Many emissions contribute to air pollution via a variety of mechanisms SCP-HAT focuses on air
pollution via particulate matter (PM) which is caused by emissions of PM itself as well as by
emissions of NH3 NOx and SO2 which form so-called secondary PM via chemical reactions The
UNEP LCI guidance for LCIA indicators (UNEP 2016) recommends the use of characterization
factors at end-point reflecting damages to human health expressed in Disability-Adjusted Life
Years (DALY) The recommended approach for calculating DALY impact factors is via emission
source archetypes but this could not be implemented at the global highly aggregated scale of
emissions data used in SCP-HAT The tool therefore uses DALY impact factors from RIVM
(Huijbregts et al 2016) which reflect country-averaged DALY impacts per unit of emission for
each of the four substances (PM25 NH3 SO2 NOx) No differentiation is made by emission source
type at this stage A recent set of new effect factors (Fantke et al 2019) is still only available
at country level without additional distinction of emission source type
The emissions data are taken from the EDGAR database (v432) This database covers all
countries and years up to and including 2012 For emissions of primary PM25 fossil and biogenic
sources are distinguished There is no difference in impact (DALYkg emitted) between those
two categories The data are extrapolated to 2013 and 2015 using GHG emissions trends with a
fixed emission ratio based on 2012 data As shown in Crippa et al (2018) emission ratios of air
pollutants to carbon dioxide have steadily decreased since 1970 but have been relatively stable
since around 2010 especially for NOx and SO2 More specifically PM25 fossil NOx and SO2 are
projected using CO2 emissions trends while CH4 and N2O (in CO2 eq) are used for PM25 bio and
NH3 During data processing it was found that this approach is not satisfactory for NH3 emissions
from agriculture and results are of especially high uncertainty for this category Thus future
improvements should prioritize this specific flow
Socio-economic data
The SCP-HAT includes a set of basic socioeconomic data which mainly serves for the estimation
of relative performance indicators of economies and industries eg carbon per unit of economic
output In the following the data sources used are listed
Population The World Bank Group
GDP The World Bank Group
Value added Eora database
Output Eora database
Employment per sector International Labour Organization
Country groups The World Bank Group
Government and private final consumption Eora database
HDI United Nations Development Programme
Country groups The World Bank Group
Employment by sector and gender is compiled from the ILO (International Labour Organization
2018) The dataset on employment by gender and sector includes only 14 sectors
Disaggregation is done using compensation to employees in Eora as proxy (ie it is assumed
same retribution between sectors belonging to an ILO category)
4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10

supported in v10 Module 3 National Data System
Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

1 Introduction
This document provides the technical documentation for the Sustainable Consumption and
Production Hotspots Analysis Tool (SCP-HAT) The SCP-HAT allows for analysing direct as well
as indirect ie trade-related impacts brought about by production and consumption activities
of national economies It is therefore able to identify hotspots related to domestic pressures and
impacts (production or territorial perspective) but also impacts occurring along the supply chains
of goods and services for final consumption in a given country The SCP-HAT provides the
possibility of analysing the performance of a large number of countries with regard to specific
environmental pressures and impacts These analyses can be conducted at national as well as
sectoral level Thereby the tool allows identifying the hotspot areas of unsustainable production
and consumption and based on this analysis supports the setting of priorities in national SCP
and climate policies for investment regulation and planning
The SCP-HAT is a web-based tool at the state of the art of web design It consists of three main
modules Module 1 ldquoCountry Profilerdquo provides the key information regarding the countryrsquos
environmental performance in the context of the most relevant SCP-related policy questions
The target users are policy makers NGOs and the general public Module 2 ldquoSCP Hotspotsrdquo
contains a wide range of SCP indicators to analyse hotspots of unsustainable consumption and
production at country and sector levels This module supports policy advisors and researchers
with expertise by means of detailed information Finally module 3 ldquoNational Data Systemrdquo
provides technical experts such as statisticians the option of inserting national data to receive
more tailored results and carry out crosschecks against the default data as contained in the
underlying model
2 Method description
Technical foundations
In its basic conception SCP-HAT is based upon an Environmentally-Extended Multi-Regional
Input-Output (EE-MRIO) model coupled with Life Cycle Assessment (LCA) for environmental
impact assessment EE-MRIO is an analytical tool supported by the UN System of Environmental-
Economic Accounting (UN-SEEA United Nations 2014) to attribute environmental pressures
and impacts to final demand categories (European Commission et al 2017) EE-MRIO adopts a
top-down approach where supply chain-wide (so-called ldquoindirectrdquo) environmental pressures and
impacts are accounted for at the macro level for broad product groups or industries This is done
by allocating domestic data on pressures (eg material extraction) and impacts (eg
deforestation) expressed in physical units (eg kg also called lsquosatellite accountsrsquo) to monetary
data on transactions among economic sectors and final consumers of different countries Hence
each monetary flow is associated with a physical equivalent (mathematical details in Annex I)
By that means double counting is avoided as the specific supply chains be they national or
international can be clearly identified form their start at resource extraction until the point of
final demand
This approach allows tracing all the pressures and impacts occurring at the different stages of even very complex supply chains and allocating them to the country of final consumption or sectoral production Hence domestic pressures (national environment) are linked to foreign consumption (countries A to F in
Figure 1Figure 1) and foreign pressures to domestic consumption This allows to analyse both
the domestic situation (ldquodomestic productionrdquo) with regard to prevailing pressures and impacts
and the role a country plays as global consumer (ldquoconsumption footprintrdquo) where the focus is
set on pressures and impacts occurring along the supply chains of consumed products
Figure 1 The basic concept of SCP-HAT
This type of analysis is used to identify hotspots of sustainable consumption and production and
opportunities for action (1) pressure or impact categories where immediate action is needed on
the national level and (2) sectors or consumption areas where the pressures or impacts caused
directly or indirectly are specifically high and action is required
In general the consumption footprint of a country is calculated by adding the pressures and
impacts related to imports to those occurring domestically and subtracting those related to the
exports It is important to note the differences between approaches based upon EE-MRIO and
those using coefficients to estimate the indirect trade flows of pressures and impacts and the
consumption footprint of a country
- Coefficient approaches calculate the total environmental pressures or impacts associated
with final consumption by accounting for physical in- and out-flows of a country and
considering the environmental intensity of the traded commodities along the whole
production chain They apply intensity coefficients ndash or ldquocradle-to-productrdquo coefficients ndash
to the specific traded products and activities Here the consumption footprint of a country
is calculated by adding the pressures and impacts related to all imports to those occurring
domestically and subtracting those related to all the exports
Coefficient approaches apply the concept of ldquoapparent consumptionrdquo ie they cannot
specify whether a certain environmental pressure or impact is associated with
intermediate production or consumed by the final consumer Accordingly trade balances
are calculated in gross terms ie considering both intermediate and final trade products
(see above) Though conceptually feasible in practice it is not possible to separate eg
private consumption from government consumption Finally often so-called ldquotruncation
errorsrdquo are produced as the indirect flows are not traced along the entire industrial supply
chains The most important advantage of coefficient-based approaches is the high level of
detail and transparency which can be applied in footprint-oriented indicator calculations
- As explained above input-output analysis allows tracing monetary flows and embodied
environmental factors from its origin (eg raw material extraction) to the final consumption
of the respective products The so-called ldquoLeontief inverserdquo a matrix generated from an
input-output table (see Annex I) shows for each commodity or industry represented in
the model all direct and indirect inputs and related environmental pressures and impacts
required along the complete supply chain Doing the calculation for all product groups all
environmental pressures and impacts needed to satisfy final demand of a country can be
quantified
A major advantage of input-output based approaches is that input-output tables
disaggregate a large number of different product groups and industries as well as final
demand categories (eg private consumption government consumption investments
etc) They allow calculating the footprints for all products and all sectors also those with
very complex supply chains and thus avoid truncation errors (see above) Finally the
countries of origin of a countryrsquos consumption footprint can be identified as well as the
countries of destination of the domestic environmental pressures and impacts
Consequently in contrast to coefficient-based approaches analyses of indirect trade flows
are done from the perspective of linking source countries with final demand in the
destination countries Hence trade analyses in Module 1 and 2 of SCP-HAT have to be
understood before this background import flows into a country of interest will only include
those pressures and impacts occurring abroad which contribute to the countryrsquos final
demand Export flows incorporate only the pressures and impacts which occur
domestically and contribute to final demand abroad Consequently flows which ldquopass
throughrdquo the country via imports and re-exports are not accounted for
When comparing results for a country of interest which stem from MRIO-based and
coefficient-based approaches conceptually the numbers for the consumption footprint can
be directly compared while those for trade flows cannot
EE-MRIO is complemented by impact assessment for the calculation of certain environmental
impact variables (using Life Cycle Impact Assessment (LCIA) characterization factors) While
environmental accounts used in EE-MRIO provide data on domestic resource use in the countries
around the world LCIA ldquotranslatesrdquo these amounts into environmental impacts such as
biodiversity loss from land use or resource depletion related to raw material use This
methodological step is realised in accordance with the LCIA guidelines set by the United Nations
Environment Programme (UNEP 2016)
Pressure and impact categories
Ideally the SCP-HAT tool would cover all indicators included in the 10-year framework of
programmes on sustainable consumption and production patterns (10YFP) Evaluation and
Monitoring Framework1 ie material use waste water use energy use GHG emissions air soil
and water pollutants biodiversity conservation and land use and human well-being indicators
related to gender decent work and health However for the development of the 2018 version
of the tool a first selection of highly relevant pressure and impact categories are implemented
Environmental pressures
o Raw material use
o Land use (occupation only)
o Emissions of greenhouse gases
o Emissions of particulate matter and precursors
Environmental impacts
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
The selection of a first set of pressures and impacts was guided by a set of criteria
Readiness of data availability
Relevance for SCP policy questions
Interrelatedness of pressures and impacts
Widely accepted impact characterization factors
Moreover the focus was set on an extensive coverage of related issues to be covered indirectly
with the selected domains For instance material flows include most energy carriers (and to a
large extend also cover energy) and allow for proxies for waste GHG emissions also have a large
overlap with energy use (more comprehensively when compared to material flows) They relate
1 httpwwwoneplanetnetworkorgresource10yfp-indicators-success
to two important policy areas of resource efficiency and climate mitigation identified as priorities
by many governments including the G7 and G20
Further categories to be integrated in future version of the SCP-HAT could include for example
Water use and water scarcity
Primary energy
Land transformation
Mercury emissions
Solid waste
Social life-cycle impacts (hazardous or child labour corruption etc)
Geographical and IndustryProduct coverage
The aim of SCP-HAT is to cover all countries in the world including those with relatively short
history of engaging more actively in policy making around policy areas such as SCP the SDGs
green economy etc The geographical coverage of SCP-HAT is based on the official list of UN
Member States2 but constrained by the country resolution of the databases utilised This choice
does not imply any political judgment All databases utilised in the SCP-HAT have their own
territorial definitions which do not always coincide especially regarding to former colonies
territories with independence partially recognized etc In total the SCP-HAT includes 171 UN
state members for which data are available in all databases There are some lsquospecial casesrsquo
Sudan includes South Sudan from 1990 to 2011 while Ethiopia includes Eritrea from 1990 to
1992 The full list is provided in Annex II The unified sector aggregation applied encompasses
26 economic sectorsproduct categories which is the level of detail of the underlying input-
output model (see below) A complete list can be found in the Annex III
3 Data sources
Multi-Regional Input-Output
There are a number of global input-output models available which allow for comprehensive EE-
MRIO modelling Depending on the political or scientific question to be answered they have their
strengths and weaknesses The input-output core applied in the SCP-HAT is the lsquoEorarsquo database
(Lenzen et al 2013 2012) Its major advantage in comparison to other available MRIO
databases is its geographical coverage of 188 single countries and thus the possibility to perform
nation-specific analysis for almost any country in the world Two Eora version are available the
2 httpwwwunorgenmember-states
Full Eora and the Eora26 The difference between them resides in the sectoral classification The
former uses the original sector disaggregation of the IO-tables as provided by the original source
Here the resolution varies between 26 and a few hundred sectors The latter applies a
harmonised 26sectors disaggregation for all countries For SCP-HAT we apply the Eora26 Even
though Full Eora can be considered more accurate using Eora26 avoids possible computational
problems since memory needs and server space would be significantly lower Time series are
available for 1990 to 2015 which is hence also the time span for the SCP-HAT
GHG emissions and Climate Change (Short-Term and Long-Term)
The UNEP LCI guidance for LCIA indicators makes an interim recommendation for considering
two impact categories for climate change short-term related to the rate of temperature change
and long-term related to the long-term temperature rise (UNEP 2016) The indicators
recommended for short-term and long-term respectively are Global Warming Potential 100
(GWP100) and Global Temperature change Potential (GTP100) at 100 years horizon The
corresponding characterization factors provided by UNEP are applied to GHG emissions data
with impact factors for 24 separate emissions including differentiation of fossil- and biogenic
methane (Full list of GWP and GTP factors in Annex IV) Near-term climate forcing gases are
excluded as the UNEP LCI guidance recommends those for sensitivity analysis only
Two sources are employed for compiling the SCP-HATrsquos GHG emissions input data The main
dataset was the PRIMAP-hist (PRIMAP ndash Potsdam Realtime Integrated Model for Probabilistic
Assessment of Emissions Paths) developed by the Potsdam Institute for Climate Impact Research
(Guumltschow et al 2019 2016) PRIMAP-hist was selected because of its coverage of long time
series and because it integrates other popular global GHG datasets (eg British Petroleum
Review of World Energy (BP 2014) Carbon Dioxide Information Analysis Center fossil fuel and
industrial CO2 emissions dataset (Boden et al 2015) the EDGAR dataset (Janssens-Maenhout
et al 2019) It includes emissions for the main Kyoto greenhouse gases carbon dioxide (CO2)
methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons
(PFCs)sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3) for the period of 1850 to 2016
The country detail is high including almost all countries considered in the SCP-HAT
The PRIMAP-hist sector categorization is based on the main Intergovernmental Panel on Climate
Change (IPCC) 2006 categories It has been analysed in the literature that too poor sector
resolution in the environmental extension of EE-MRIO models can cause aggregation errors
(Steen-Olsen et al 2014 Su et al 2010) and inclusion of external data for further
disaggregation is recommended (Lenzen 2011) To prevent this aggregation bias the PRIMAP-
hist data is further disaggregated using GHG emissions shares from the EDGAR database which
is maintained by the European Commission Joint Research Centre (JRC) and the Netherlands
Environmental Assessment Agency (PBL) (Janssens-Maenhout et al 2019 Olivier and Janssens-
Maenhout 2012) The shares of the different IPCC categories contributing to the total as reported
by EDGAR were applied to the totals published by PRIMAP-hist and used for SCP-HAT Three
specific EDGAR datasets are utilized the Edgar version 432 the EDGAR version 42 Fast Track
(FT) 2010 and the EDGAR version 42 For CO2 CH4 and N2O and the whole period Edgar
version 432 was used For SF6 the Edgar version 42 was used for the period 1990-1999 and
the Edgar version 42 FT for the period 2000-2010 Edgar shares from version 42 were adjusted
using the same approach as FAOSTAT for compiling their ldquoEmissions by sectorrdquo3 dataset For
HFCs and PFCs the EDGAR version 42 FT 2010 was used and shares from 2000 were assumed
as being equal for the period 1990-1999 For HFCs PFCs and SF6 shares for 2010 from Edgar
FT 2010 were applied for the disaggregation of the years 2011 to 2015 After the disaggregation
of the PRIMAP-hist data the IPCC 2006 categories were allocated to one or more sectors of the
SCP-HAT (ie Eora 26 sectors) The IPCC 2006 sector classification in the SCP-HAT and the
correspondence to the SCP-HAT sectors is provided in Annex V For those categories allocated
to more than one sector the emissions were disaggregated according to the relationship of the
total output of the sectors
Lastly emissions from road transportation from industries and households are recorded together
in PRIMAP-hits and EDGAR which need to be disaggregated for a finer analysis in the SCP-HAT
This was done applying the shares of different industries and households in the overall use of
the category lsquoPetroleum Chemical and Non-Metallic Mineral Productsrsquo as provided in Eora
Raw material use and mineral and fossil resource scarcity
For physical data for raw material extraction data from UN IRP Global Material Flows Database
(UN IRP 2017) are used It includes 13 aggregated raw material categories compiled following
lsquoeconomy-wide material flow accountingrsquo principles (Eurostat 2013 OECD 2008) for 192
countries including most of the countries of the SCP-HAT A full list of the raw material extraction
categories can be found in Annex VI National material extraction is allocated to the three
extractive sectors contained in the Eora26 sector classification ndash lsquoagriculturersquo lsquofishingrsquo and
lsquomining and quarryingrsquo While such a high aggregation of extractive sectors can result in a
distortion of the overall results (de Koning et al 2015 Pintildeero et al 2014) an improvement by
means for instance of allocating the extractions to intermediate users (Giljum et al 2017
Schaffartzik et al 2013 Wiebe et al 2012) ndash eg iron from mining to the steel industry ndash is
implemented in some cases The resulting allocation is sometimes referred as lsquouse extensionrsquo in
contrast to the most common lsquosupply extensionrsquo (further details in Annex I)
3 See httpwwwfaoorgfaostatendataEM
Raw material extraction for abiotic materials is translated into impacts by using the mineral and
fossil resource scarcity characterization factors from the Dutch National Institute for Public Health
and the Environment (RIVM) (Huijbregts et al 2016) The midpoint indicator (ie focussing on
intermediate stage along the impact pathway) for fossil resource scarcity is defined as the ratio
between the energy content of fossil resource x and the energy content of crude oil The unit of
this indicator is kg oil-equivalent and it simply reflects the energy content compared to a kilogram
of oil The characterization method for mineral resource scarcity is Surplus Ore Potential which
expresses the average extra amount of ore to be produced in the future due to the extraction of
1 kg of a mineral resource x In other words this reflects the decrease in ore grade of remaining
reserves The indicator is expressed relative to copper in units of kg Cu-equivalent The
ldquohierarchistrdquo version of this indicator is applied which means that future production is chosen to
be the ultimate recoverable resource For more details see RIVM (Huijbregts et al 2016) An
unweighted average characterization factor for the group of ldquoOther metalsrdquo was derived using
the 25 materials listed in that category in the Global Material Flows Database The resulting
factor was dominated by caesium which is probably higher than realistic In version 11 the
characterization factor for the group of ldquoOther metalsrdquo was updated by using a global-production-
weighted average (averaged over the years 2012-2014 as data for some metals are only
available after 2012) This resulted in a significant reduction of the factor with the main
contributors being mercury magnesium zirconium and hafnium
Land use and potential species loss from land use
The UNEP LCI guidance for LCIA indicators makes an interim recommendation (see UNEP 2016)
for characterization of biodiversity impacts of land use discerning occupation and
transformation based on the method developed by Chaudhary et al (2015) In this first version
of the SCP-HAT only land occupation is included and modelling of land transformation is left for
future tool developments To allow for the application of the recommended characterization
factors inventory data is required for land occupation (m2a) for six land use classes - Annual
crops Permanent crops Pasture Extensive forestry Intensive forestry Urban Annex VII shows
sector correspondence for the land use categories in the SCP-HAT Land use for crops and
pasture is allocated partly to the agriculture sector and partly to final demand The allocation to
final demand is made based on data on subsistence and low-input crop farming derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) For details on the
allocation methodology see Annex XXI Land use for intensive forestry is allocated to the wood
and paper industry (ie allocation to first intermediate users see Annex I) Land use for
extensive forestry is allocated partly to the wood and paper industry and partly to final demand
based on domestic wood fuel production and consumption statistics For details on the allocation
methodology see Annex XXI
Land use for other industrial activities than agriculture or forestry (eg mining) is not covered
From version v11 onwards built-up land is allocated directly to final demand and estimated
using OECD land use statistics (OECD 2018)
The definition of the two forestry land use classes used for the impact characterization is i)
Intensive Forest forests with extractive use with either even-aged stands and clear-cut
patches or less than three naturally occurring species at plantingseeding and ii) Extensive
Forests forests with extractive use and associated disturbance like hunting and selective
logging where timber extraction is followed by re-growth including at least three naturally
occurring tree species For the latter alternative uses to wood and paper eg recreation
hunting etc are not considered
Land use data for Annual crops Permanent crops and Pasture are gathered from FAOSTATrsquos
databases for the analogous categories arable land permanent crops and permanent meadows
and pastures (Food and Agriculture Organization of the United Nations 2018) Table 1 shows
data sources and model description for Extensive and Intensive Forestry
Following UNEPrsquos recommendations country-level average characterization factors for global
species loss from Chaudhary et al (2015) are used in the SCP-HAT aggregated over five taxa
(mammals reptiles birds amphibians and vascular plants) for each of the six land use
categories The unit of this indicator is PDFyear which stands for the Potentially Disappeared
Fraction of species for the duration of a year Land use impact modelling assumes that once an
activity (land use) stops the system will slowly return to the natural state The indicator
therefore does not reflect full extinction of species but a temporary decline in biodiversity

Air pollution and health impacts
Many emissions contribute to air pollution via a variety of mechanisms SCP-HAT focuses on air
pollution via particulate matter (PM) which is caused by emissions of PM itself as well as by
emissions of NH3 NOx and SO2 which form so-called secondary PM via chemical reactions The
UNEP LCI guidance for LCIA indicators (UNEP 2016) recommends the use of characterization
factors at end-point reflecting damages to human health expressed in Disability-Adjusted Life
Years (DALY) The recommended approach for calculating DALY impact factors is via emission
source archetypes but this could not be implemented at the global highly aggregated scale of
emissions data used in SCP-HAT The tool therefore uses DALY impact factors from RIVM
(Huijbregts et al 2016) which reflect country-averaged DALY impacts per unit of emission for
each of the four substances (PM25 NH3 SO2 NOx) No differentiation is made by emission source
type at this stage A recent set of new effect factors (Fantke et al 2019) is still only available
at country level without additional distinction of emission source type
The emissions data are taken from the EDGAR database (v432) This database covers all
countries and years up to and including 2012 For emissions of primary PM25 fossil and biogenic
sources are distinguished There is no difference in impact (DALYkg emitted) between those
two categories The data are extrapolated to 2013 and 2015 using GHG emissions trends with a
fixed emission ratio based on 2012 data As shown in Crippa et al (2018) emission ratios of air
pollutants to carbon dioxide have steadily decreased since 1970 but have been relatively stable
since around 2010 especially for NOx and SO2 More specifically PM25 fossil NOx and SO2 are
projected using CO2 emissions trends while CH4 and N2O (in CO2 eq) are used for PM25 bio and
NH3 During data processing it was found that this approach is not satisfactory for NH3 emissions
from agriculture and results are of especially high uncertainty for this category Thus future
improvements should prioritize this specific flow
Socio-economic data
The SCP-HAT includes a set of basic socioeconomic data which mainly serves for the estimation
of relative performance indicators of economies and industries eg carbon per unit of economic
output In the following the data sources used are listed
Population The World Bank Group
GDP The World Bank Group
Value added Eora database
Output Eora database
Employment per sector International Labour Organization
Country groups The World Bank Group
Government and private final consumption Eora database
HDI United Nations Development Programme
Country groups The World Bank Group
Employment by sector and gender is compiled from the ILO (International Labour Organization
2018) The dataset on employment by gender and sector includes only 14 sectors
Disaggregation is done using compensation to employees in Eora as proxy (ie it is assumed
same retribution between sectors belonging to an ILO category)
4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10

supported in v10 Module 3 National Data System
Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

Pastures
In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

1 Introduction
This document provides the technical documentation for the Sustainable Consumption and
Production Hotspots Analysis Tool (SCP-HAT) The SCP-HAT allows for analysing direct as well
as indirect ie trade-related impacts brought about by production and consumption activities
of national economies It is therefore able to identify hotspots related to domestic pressures and
impacts (production or territorial perspective) but also impacts occurring along the supply chains
of goods and services for final consumption in a given country The SCP-HAT provides the
possibility of analysing the performance of a large number of countries with regard to specific
environmental pressures and impacts These analyses can be conducted at national as well as
sectoral level Thereby the tool allows identifying the hotspot areas of unsustainable production
and consumption and based on this analysis supports the setting of priorities in national SCP
and climate policies for investment regulation and planning
The SCP-HAT is a web-based tool at the state of the art of web design It consists of three main
modules Module 1 ldquoCountry Profilerdquo provides the key information regarding the countryrsquos
environmental performance in the context of the most relevant SCP-related policy questions
The target users are policy makers NGOs and the general public Module 2 ldquoSCP Hotspotsrdquo
contains a wide range of SCP indicators to analyse hotspots of unsustainable consumption and
production at country and sector levels This module supports policy advisors and researchers
with expertise by means of detailed information Finally module 3 ldquoNational Data Systemrdquo
provides technical experts such as statisticians the option of inserting national data to receive
more tailored results and carry out crosschecks against the default data as contained in the
underlying model
2 Method description
Technical foundations
In its basic conception SCP-HAT is based upon an Environmentally-Extended Multi-Regional
Input-Output (EE-MRIO) model coupled with Life Cycle Assessment (LCA) for environmental
impact assessment EE-MRIO is an analytical tool supported by the UN System of Environmental-
Economic Accounting (UN-SEEA United Nations 2014) to attribute environmental pressures
and impacts to final demand categories (European Commission et al 2017) EE-MRIO adopts a
top-down approach where supply chain-wide (so-called ldquoindirectrdquo) environmental pressures and
impacts are accounted for at the macro level for broad product groups or industries This is done
by allocating domestic data on pressures (eg material extraction) and impacts (eg
deforestation) expressed in physical units (eg kg also called lsquosatellite accountsrsquo) to monetary
data on transactions among economic sectors and final consumers of different countries Hence
each monetary flow is associated with a physical equivalent (mathematical details in Annex I)
By that means double counting is avoided as the specific supply chains be they national or
international can be clearly identified form their start at resource extraction until the point of
final demand
This approach allows tracing all the pressures and impacts occurring at the different stages of even very complex supply chains and allocating them to the country of final consumption or sectoral production Hence domestic pressures (national environment) are linked to foreign consumption (countries A to F in
Figure 1Figure 1) and foreign pressures to domestic consumption This allows to analyse both
the domestic situation (ldquodomestic productionrdquo) with regard to prevailing pressures and impacts
and the role a country plays as global consumer (ldquoconsumption footprintrdquo) where the focus is
set on pressures and impacts occurring along the supply chains of consumed products
Figure 1 The basic concept of SCP-HAT
This type of analysis is used to identify hotspots of sustainable consumption and production and
opportunities for action (1) pressure or impact categories where immediate action is needed on
the national level and (2) sectors or consumption areas where the pressures or impacts caused
directly or indirectly are specifically high and action is required
In general the consumption footprint of a country is calculated by adding the pressures and
impacts related to imports to those occurring domestically and subtracting those related to the
exports It is important to note the differences between approaches based upon EE-MRIO and
those using coefficients to estimate the indirect trade flows of pressures and impacts and the
consumption footprint of a country
- Coefficient approaches calculate the total environmental pressures or impacts associated
with final consumption by accounting for physical in- and out-flows of a country and
considering the environmental intensity of the traded commodities along the whole
production chain They apply intensity coefficients ndash or ldquocradle-to-productrdquo coefficients ndash
to the specific traded products and activities Here the consumption footprint of a country
is calculated by adding the pressures and impacts related to all imports to those occurring
domestically and subtracting those related to all the exports
Coefficient approaches apply the concept of ldquoapparent consumptionrdquo ie they cannot
specify whether a certain environmental pressure or impact is associated with
intermediate production or consumed by the final consumer Accordingly trade balances
are calculated in gross terms ie considering both intermediate and final trade products
(see above) Though conceptually feasible in practice it is not possible to separate eg
private consumption from government consumption Finally often so-called ldquotruncation
errorsrdquo are produced as the indirect flows are not traced along the entire industrial supply
chains The most important advantage of coefficient-based approaches is the high level of
detail and transparency which can be applied in footprint-oriented indicator calculations
- As explained above input-output analysis allows tracing monetary flows and embodied
environmental factors from its origin (eg raw material extraction) to the final consumption
of the respective products The so-called ldquoLeontief inverserdquo a matrix generated from an
input-output table (see Annex I) shows for each commodity or industry represented in
the model all direct and indirect inputs and related environmental pressures and impacts
required along the complete supply chain Doing the calculation for all product groups all
environmental pressures and impacts needed to satisfy final demand of a country can be
quantified
A major advantage of input-output based approaches is that input-output tables
disaggregate a large number of different product groups and industries as well as final
demand categories (eg private consumption government consumption investments
etc) They allow calculating the footprints for all products and all sectors also those with
very complex supply chains and thus avoid truncation errors (see above) Finally the
countries of origin of a countryrsquos consumption footprint can be identified as well as the
countries of destination of the domestic environmental pressures and impacts
Consequently in contrast to coefficient-based approaches analyses of indirect trade flows
are done from the perspective of linking source countries with final demand in the
destination countries Hence trade analyses in Module 1 and 2 of SCP-HAT have to be
understood before this background import flows into a country of interest will only include
those pressures and impacts occurring abroad which contribute to the countryrsquos final
demand Export flows incorporate only the pressures and impacts which occur
domestically and contribute to final demand abroad Consequently flows which ldquopass
throughrdquo the country via imports and re-exports are not accounted for
When comparing results for a country of interest which stem from MRIO-based and
coefficient-based approaches conceptually the numbers for the consumption footprint can
be directly compared while those for trade flows cannot
EE-MRIO is complemented by impact assessment for the calculation of certain environmental
impact variables (using Life Cycle Impact Assessment (LCIA) characterization factors) While
environmental accounts used in EE-MRIO provide data on domestic resource use in the countries
around the world LCIA ldquotranslatesrdquo these amounts into environmental impacts such as
biodiversity loss from land use or resource depletion related to raw material use This
methodological step is realised in accordance with the LCIA guidelines set by the United Nations
Environment Programme (UNEP 2016)
Pressure and impact categories
Ideally the SCP-HAT tool would cover all indicators included in the 10-year framework of
programmes on sustainable consumption and production patterns (10YFP) Evaluation and
Monitoring Framework1 ie material use waste water use energy use GHG emissions air soil
and water pollutants biodiversity conservation and land use and human well-being indicators
related to gender decent work and health However for the development of the 2018 version
of the tool a first selection of highly relevant pressure and impact categories are implemented
Environmental pressures
o Raw material use
o Land use (occupation only)
o Emissions of greenhouse gases
o Emissions of particulate matter and precursors
Environmental impacts
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
The selection of a first set of pressures and impacts was guided by a set of criteria
Readiness of data availability
Relevance for SCP policy questions
Interrelatedness of pressures and impacts
Widely accepted impact characterization factors
Moreover the focus was set on an extensive coverage of related issues to be covered indirectly
with the selected domains For instance material flows include most energy carriers (and to a
large extend also cover energy) and allow for proxies for waste GHG emissions also have a large
overlap with energy use (more comprehensively when compared to material flows) They relate
1 httpwwwoneplanetnetworkorgresource10yfp-indicators-success
to two important policy areas of resource efficiency and climate mitigation identified as priorities
by many governments including the G7 and G20
Further categories to be integrated in future version of the SCP-HAT could include for example
Water use and water scarcity
Primary energy
Land transformation
Mercury emissions
Solid waste
Social life-cycle impacts (hazardous or child labour corruption etc)
Geographical and IndustryProduct coverage
The aim of SCP-HAT is to cover all countries in the world including those with relatively short
history of engaging more actively in policy making around policy areas such as SCP the SDGs
green economy etc The geographical coverage of SCP-HAT is based on the official list of UN
Member States2 but constrained by the country resolution of the databases utilised This choice
does not imply any political judgment All databases utilised in the SCP-HAT have their own
territorial definitions which do not always coincide especially regarding to former colonies
territories with independence partially recognized etc In total the SCP-HAT includes 171 UN
state members for which data are available in all databases There are some lsquospecial casesrsquo
Sudan includes South Sudan from 1990 to 2011 while Ethiopia includes Eritrea from 1990 to
1992 The full list is provided in Annex II The unified sector aggregation applied encompasses
26 economic sectorsproduct categories which is the level of detail of the underlying input-
output model (see below) A complete list can be found in the Annex III
3 Data sources
Multi-Regional Input-Output
There are a number of global input-output models available which allow for comprehensive EE-
MRIO modelling Depending on the political or scientific question to be answered they have their
strengths and weaknesses The input-output core applied in the SCP-HAT is the lsquoEorarsquo database
(Lenzen et al 2013 2012) Its major advantage in comparison to other available MRIO
databases is its geographical coverage of 188 single countries and thus the possibility to perform
nation-specific analysis for almost any country in the world Two Eora version are available the
2 httpwwwunorgenmember-states
Full Eora and the Eora26 The difference between them resides in the sectoral classification The
former uses the original sector disaggregation of the IO-tables as provided by the original source
Here the resolution varies between 26 and a few hundred sectors The latter applies a
harmonised 26sectors disaggregation for all countries For SCP-HAT we apply the Eora26 Even
though Full Eora can be considered more accurate using Eora26 avoids possible computational
problems since memory needs and server space would be significantly lower Time series are
available for 1990 to 2015 which is hence also the time span for the SCP-HAT
GHG emissions and Climate Change (Short-Term and Long-Term)
The UNEP LCI guidance for LCIA indicators makes an interim recommendation for considering
two impact categories for climate change short-term related to the rate of temperature change
and long-term related to the long-term temperature rise (UNEP 2016) The indicators
recommended for short-term and long-term respectively are Global Warming Potential 100
(GWP100) and Global Temperature change Potential (GTP100) at 100 years horizon The
corresponding characterization factors provided by UNEP are applied to GHG emissions data
with impact factors for 24 separate emissions including differentiation of fossil- and biogenic
methane (Full list of GWP and GTP factors in Annex IV) Near-term climate forcing gases are
excluded as the UNEP LCI guidance recommends those for sensitivity analysis only
Two sources are employed for compiling the SCP-HATrsquos GHG emissions input data The main
dataset was the PRIMAP-hist (PRIMAP ndash Potsdam Realtime Integrated Model for Probabilistic
Assessment of Emissions Paths) developed by the Potsdam Institute for Climate Impact Research
(Guumltschow et al 2019 2016) PRIMAP-hist was selected because of its coverage of long time
series and because it integrates other popular global GHG datasets (eg British Petroleum
Review of World Energy (BP 2014) Carbon Dioxide Information Analysis Center fossil fuel and
industrial CO2 emissions dataset (Boden et al 2015) the EDGAR dataset (Janssens-Maenhout
et al 2019) It includes emissions for the main Kyoto greenhouse gases carbon dioxide (CO2)
methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons
(PFCs)sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3) for the period of 1850 to 2016
The country detail is high including almost all countries considered in the SCP-HAT
The PRIMAP-hist sector categorization is based on the main Intergovernmental Panel on Climate
Change (IPCC) 2006 categories It has been analysed in the literature that too poor sector
resolution in the environmental extension of EE-MRIO models can cause aggregation errors
(Steen-Olsen et al 2014 Su et al 2010) and inclusion of external data for further
disaggregation is recommended (Lenzen 2011) To prevent this aggregation bias the PRIMAP-
hist data is further disaggregated using GHG emissions shares from the EDGAR database which
is maintained by the European Commission Joint Research Centre (JRC) and the Netherlands
Environmental Assessment Agency (PBL) (Janssens-Maenhout et al 2019 Olivier and Janssens-
Maenhout 2012) The shares of the different IPCC categories contributing to the total as reported
by EDGAR were applied to the totals published by PRIMAP-hist and used for SCP-HAT Three
specific EDGAR datasets are utilized the Edgar version 432 the EDGAR version 42 Fast Track
(FT) 2010 and the EDGAR version 42 For CO2 CH4 and N2O and the whole period Edgar
version 432 was used For SF6 the Edgar version 42 was used for the period 1990-1999 and
the Edgar version 42 FT for the period 2000-2010 Edgar shares from version 42 were adjusted
using the same approach as FAOSTAT for compiling their ldquoEmissions by sectorrdquo3 dataset For
HFCs and PFCs the EDGAR version 42 FT 2010 was used and shares from 2000 were assumed
as being equal for the period 1990-1999 For HFCs PFCs and SF6 shares for 2010 from Edgar
FT 2010 were applied for the disaggregation of the years 2011 to 2015 After the disaggregation
of the PRIMAP-hist data the IPCC 2006 categories were allocated to one or more sectors of the
SCP-HAT (ie Eora 26 sectors) The IPCC 2006 sector classification in the SCP-HAT and the
correspondence to the SCP-HAT sectors is provided in Annex V For those categories allocated
to more than one sector the emissions were disaggregated according to the relationship of the
total output of the sectors
Lastly emissions from road transportation from industries and households are recorded together
in PRIMAP-hits and EDGAR which need to be disaggregated for a finer analysis in the SCP-HAT
This was done applying the shares of different industries and households in the overall use of
the category lsquoPetroleum Chemical and Non-Metallic Mineral Productsrsquo as provided in Eora
Raw material use and mineral and fossil resource scarcity
For physical data for raw material extraction data from UN IRP Global Material Flows Database
(UN IRP 2017) are used It includes 13 aggregated raw material categories compiled following
lsquoeconomy-wide material flow accountingrsquo principles (Eurostat 2013 OECD 2008) for 192
countries including most of the countries of the SCP-HAT A full list of the raw material extraction
categories can be found in Annex VI National material extraction is allocated to the three
extractive sectors contained in the Eora26 sector classification ndash lsquoagriculturersquo lsquofishingrsquo and
lsquomining and quarryingrsquo While such a high aggregation of extractive sectors can result in a
distortion of the overall results (de Koning et al 2015 Pintildeero et al 2014) an improvement by
means for instance of allocating the extractions to intermediate users (Giljum et al 2017
Schaffartzik et al 2013 Wiebe et al 2012) ndash eg iron from mining to the steel industry ndash is
implemented in some cases The resulting allocation is sometimes referred as lsquouse extensionrsquo in
contrast to the most common lsquosupply extensionrsquo (further details in Annex I)
3 See httpwwwfaoorgfaostatendataEM
Raw material extraction for abiotic materials is translated into impacts by using the mineral and
fossil resource scarcity characterization factors from the Dutch National Institute for Public Health
and the Environment (RIVM) (Huijbregts et al 2016) The midpoint indicator (ie focussing on
intermediate stage along the impact pathway) for fossil resource scarcity is defined as the ratio
between the energy content of fossil resource x and the energy content of crude oil The unit of
this indicator is kg oil-equivalent and it simply reflects the energy content compared to a kilogram
of oil The characterization method for mineral resource scarcity is Surplus Ore Potential which
expresses the average extra amount of ore to be produced in the future due to the extraction of
1 kg of a mineral resource x In other words this reflects the decrease in ore grade of remaining
reserves The indicator is expressed relative to copper in units of kg Cu-equivalent The
ldquohierarchistrdquo version of this indicator is applied which means that future production is chosen to
be the ultimate recoverable resource For more details see RIVM (Huijbregts et al 2016) An
unweighted average characterization factor for the group of ldquoOther metalsrdquo was derived using
the 25 materials listed in that category in the Global Material Flows Database The resulting
factor was dominated by caesium which is probably higher than realistic In version 11 the
characterization factor for the group of ldquoOther metalsrdquo was updated by using a global-production-
weighted average (averaged over the years 2012-2014 as data for some metals are only
available after 2012) This resulted in a significant reduction of the factor with the main
contributors being mercury magnesium zirconium and hafnium
Land use and potential species loss from land use
The UNEP LCI guidance for LCIA indicators makes an interim recommendation (see UNEP 2016)
for characterization of biodiversity impacts of land use discerning occupation and
transformation based on the method developed by Chaudhary et al (2015) In this first version
of the SCP-HAT only land occupation is included and modelling of land transformation is left for
future tool developments To allow for the application of the recommended characterization
factors inventory data is required for land occupation (m2a) for six land use classes - Annual
crops Permanent crops Pasture Extensive forestry Intensive forestry Urban Annex VII shows
sector correspondence for the land use categories in the SCP-HAT Land use for crops and
pasture is allocated partly to the agriculture sector and partly to final demand The allocation to
final demand is made based on data on subsistence and low-input crop farming derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) For details on the
allocation methodology see Annex XXI Land use for intensive forestry is allocated to the wood
and paper industry (ie allocation to first intermediate users see Annex I) Land use for
extensive forestry is allocated partly to the wood and paper industry and partly to final demand
based on domestic wood fuel production and consumption statistics For details on the allocation
methodology see Annex XXI
Land use for other industrial activities than agriculture or forestry (eg mining) is not covered
From version v11 onwards built-up land is allocated directly to final demand and estimated
using OECD land use statistics (OECD 2018)
The definition of the two forestry land use classes used for the impact characterization is i)
Intensive Forest forests with extractive use with either even-aged stands and clear-cut
patches or less than three naturally occurring species at plantingseeding and ii) Extensive
Forests forests with extractive use and associated disturbance like hunting and selective
logging where timber extraction is followed by re-growth including at least three naturally
occurring tree species For the latter alternative uses to wood and paper eg recreation
hunting etc are not considered
Land use data for Annual crops Permanent crops and Pasture are gathered from FAOSTATrsquos
databases for the analogous categories arable land permanent crops and permanent meadows
and pastures (Food and Agriculture Organization of the United Nations 2018) Table 1 shows
data sources and model description for Extensive and Intensive Forestry
Following UNEPrsquos recommendations country-level average characterization factors for global
species loss from Chaudhary et al (2015) are used in the SCP-HAT aggregated over five taxa
(mammals reptiles birds amphibians and vascular plants) for each of the six land use
categories The unit of this indicator is PDFyear which stands for the Potentially Disappeared
Fraction of species for the duration of a year Land use impact modelling assumes that once an
activity (land use) stops the system will slowly return to the natural state The indicator
therefore does not reflect full extinction of species but a temporary decline in biodiversity

Air pollution and health impacts
Many emissions contribute to air pollution via a variety of mechanisms SCP-HAT focuses on air
pollution via particulate matter (PM) which is caused by emissions of PM itself as well as by
emissions of NH3 NOx and SO2 which form so-called secondary PM via chemical reactions The
UNEP LCI guidance for LCIA indicators (UNEP 2016) recommends the use of characterization
factors at end-point reflecting damages to human health expressed in Disability-Adjusted Life
Years (DALY) The recommended approach for calculating DALY impact factors is via emission
source archetypes but this could not be implemented at the global highly aggregated scale of
emissions data used in SCP-HAT The tool therefore uses DALY impact factors from RIVM
(Huijbregts et al 2016) which reflect country-averaged DALY impacts per unit of emission for
each of the four substances (PM25 NH3 SO2 NOx) No differentiation is made by emission source
type at this stage A recent set of new effect factors (Fantke et al 2019) is still only available
at country level without additional distinction of emission source type
The emissions data are taken from the EDGAR database (v432) This database covers all
countries and years up to and including 2012 For emissions of primary PM25 fossil and biogenic
sources are distinguished There is no difference in impact (DALYkg emitted) between those
two categories The data are extrapolated to 2013 and 2015 using GHG emissions trends with a
fixed emission ratio based on 2012 data As shown in Crippa et al (2018) emission ratios of air
pollutants to carbon dioxide have steadily decreased since 1970 but have been relatively stable
since around 2010 especially for NOx and SO2 More specifically PM25 fossil NOx and SO2 are
projected using CO2 emissions trends while CH4 and N2O (in CO2 eq) are used for PM25 bio and
NH3 During data processing it was found that this approach is not satisfactory for NH3 emissions
from agriculture and results are of especially high uncertainty for this category Thus future
improvements should prioritize this specific flow
Socio-economic data
The SCP-HAT includes a set of basic socioeconomic data which mainly serves for the estimation
of relative performance indicators of economies and industries eg carbon per unit of economic
output In the following the data sources used are listed
Population The World Bank Group
GDP The World Bank Group
Value added Eora database
Output Eora database
Employment per sector International Labour Organization
Country groups The World Bank Group
Government and private final consumption Eora database
HDI United Nations Development Programme
Country groups The World Bank Group
Employment by sector and gender is compiled from the ILO (International Labour Organization
2018) The dataset on employment by gender and sector includes only 14 sectors
Disaggregation is done using compensation to employees in Eora as proxy (ie it is assumed
same retribution between sectors belonging to an ILO category)
4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10

supported in v10 Module 3 National Data System
Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

Pastures
In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

1 Introduction
This document provides the technical documentation for the Sustainable Consumption and
Production Hotspots Analysis Tool (SCP-HAT) The SCP-HAT allows for analysing direct as well
as indirect ie trade-related impacts brought about by production and consumption activities
of national economies It is therefore able to identify hotspots related to domestic pressures and
impacts (production or territorial perspective) but also impacts occurring along the supply chains
of goods and services for final consumption in a given country The SCP-HAT provides the
possibility of analysing the performance of a large number of countries with regard to specific
environmental pressures and impacts These analyses can be conducted at national as well as
sectoral level Thereby the tool allows identifying the hotspot areas of unsustainable production
and consumption and based on this analysis supports the setting of priorities in national SCP
and climate policies for investment regulation and planning
The SCP-HAT is a web-based tool at the state of the art of web design It consists of three main
modules Module 1 ldquoCountry Profilerdquo provides the key information regarding the countryrsquos
environmental performance in the context of the most relevant SCP-related policy questions
The target users are policy makers NGOs and the general public Module 2 ldquoSCP Hotspotsrdquo
contains a wide range of SCP indicators to analyse hotspots of unsustainable consumption and
production at country and sector levels This module supports policy advisors and researchers
with expertise by means of detailed information Finally module 3 ldquoNational Data Systemrdquo
provides technical experts such as statisticians the option of inserting national data to receive
more tailored results and carry out crosschecks against the default data as contained in the
underlying model
2 Method description
Technical foundations
In its basic conception SCP-HAT is based upon an Environmentally-Extended Multi-Regional
Input-Output (EE-MRIO) model coupled with Life Cycle Assessment (LCA) for environmental
impact assessment EE-MRIO is an analytical tool supported by the UN System of Environmental-
Economic Accounting (UN-SEEA United Nations 2014) to attribute environmental pressures
and impacts to final demand categories (European Commission et al 2017) EE-MRIO adopts a
top-down approach where supply chain-wide (so-called ldquoindirectrdquo) environmental pressures and
impacts are accounted for at the macro level for broad product groups or industries This is done
by allocating domestic data on pressures (eg material extraction) and impacts (eg
deforestation) expressed in physical units (eg kg also called lsquosatellite accountsrsquo) to monetary
data on transactions among economic sectors and final consumers of different countries Hence
each monetary flow is associated with a physical equivalent (mathematical details in Annex I)
By that means double counting is avoided as the specific supply chains be they national or
international can be clearly identified form their start at resource extraction until the point of
final demand
This approach allows tracing all the pressures and impacts occurring at the different stages of even very complex supply chains and allocating them to the country of final consumption or sectoral production Hence domestic pressures (national environment) are linked to foreign consumption (countries A to F in
Figure 1Figure 1) and foreign pressures to domestic consumption This allows to analyse both
the domestic situation (ldquodomestic productionrdquo) with regard to prevailing pressures and impacts
and the role a country plays as global consumer (ldquoconsumption footprintrdquo) where the focus is
set on pressures and impacts occurring along the supply chains of consumed products
Figure 1 The basic concept of SCP-HAT
This type of analysis is used to identify hotspots of sustainable consumption and production and
opportunities for action (1) pressure or impact categories where immediate action is needed on
the national level and (2) sectors or consumption areas where the pressures or impacts caused
directly or indirectly are specifically high and action is required
In general the consumption footprint of a country is calculated by adding the pressures and
impacts related to imports to those occurring domestically and subtracting those related to the
exports It is important to note the differences between approaches based upon EE-MRIO and
those using coefficients to estimate the indirect trade flows of pressures and impacts and the
consumption footprint of a country
- Coefficient approaches calculate the total environmental pressures or impacts associated
with final consumption by accounting for physical in- and out-flows of a country and
considering the environmental intensity of the traded commodities along the whole
production chain They apply intensity coefficients ndash or ldquocradle-to-productrdquo coefficients ndash
to the specific traded products and activities Here the consumption footprint of a country
is calculated by adding the pressures and impacts related to all imports to those occurring
domestically and subtracting those related to all the exports
Coefficient approaches apply the concept of ldquoapparent consumptionrdquo ie they cannot
specify whether a certain environmental pressure or impact is associated with
intermediate production or consumed by the final consumer Accordingly trade balances
are calculated in gross terms ie considering both intermediate and final trade products
(see above) Though conceptually feasible in practice it is not possible to separate eg
private consumption from government consumption Finally often so-called ldquotruncation
errorsrdquo are produced as the indirect flows are not traced along the entire industrial supply
chains The most important advantage of coefficient-based approaches is the high level of
detail and transparency which can be applied in footprint-oriented indicator calculations
- As explained above input-output analysis allows tracing monetary flows and embodied
environmental factors from its origin (eg raw material extraction) to the final consumption
of the respective products The so-called ldquoLeontief inverserdquo a matrix generated from an
input-output table (see Annex I) shows for each commodity or industry represented in
the model all direct and indirect inputs and related environmental pressures and impacts
required along the complete supply chain Doing the calculation for all product groups all
environmental pressures and impacts needed to satisfy final demand of a country can be
quantified
A major advantage of input-output based approaches is that input-output tables
disaggregate a large number of different product groups and industries as well as final
demand categories (eg private consumption government consumption investments
etc) They allow calculating the footprints for all products and all sectors also those with
very complex supply chains and thus avoid truncation errors (see above) Finally the
countries of origin of a countryrsquos consumption footprint can be identified as well as the
countries of destination of the domestic environmental pressures and impacts
Consequently in contrast to coefficient-based approaches analyses of indirect trade flows
are done from the perspective of linking source countries with final demand in the
destination countries Hence trade analyses in Module 1 and 2 of SCP-HAT have to be
understood before this background import flows into a country of interest will only include
those pressures and impacts occurring abroad which contribute to the countryrsquos final
demand Export flows incorporate only the pressures and impacts which occur
domestically and contribute to final demand abroad Consequently flows which ldquopass
throughrdquo the country via imports and re-exports are not accounted for
When comparing results for a country of interest which stem from MRIO-based and
coefficient-based approaches conceptually the numbers for the consumption footprint can
be directly compared while those for trade flows cannot
EE-MRIO is complemented by impact assessment for the calculation of certain environmental
impact variables (using Life Cycle Impact Assessment (LCIA) characterization factors) While
environmental accounts used in EE-MRIO provide data on domestic resource use in the countries
around the world LCIA ldquotranslatesrdquo these amounts into environmental impacts such as
biodiversity loss from land use or resource depletion related to raw material use This
methodological step is realised in accordance with the LCIA guidelines set by the United Nations
Environment Programme (UNEP 2016)
Pressure and impact categories
Ideally the SCP-HAT tool would cover all indicators included in the 10-year framework of
programmes on sustainable consumption and production patterns (10YFP) Evaluation and
Monitoring Framework1 ie material use waste water use energy use GHG emissions air soil
and water pollutants biodiversity conservation and land use and human well-being indicators
related to gender decent work and health However for the development of the 2018 version
of the tool a first selection of highly relevant pressure and impact categories are implemented
Environmental pressures
o Raw material use
o Land use (occupation only)
o Emissions of greenhouse gases
o Emissions of particulate matter and precursors
Environmental impacts
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
The selection of a first set of pressures and impacts was guided by a set of criteria
Readiness of data availability
Relevance for SCP policy questions
Interrelatedness of pressures and impacts
Widely accepted impact characterization factors
Moreover the focus was set on an extensive coverage of related issues to be covered indirectly
with the selected domains For instance material flows include most energy carriers (and to a
large extend also cover energy) and allow for proxies for waste GHG emissions also have a large
overlap with energy use (more comprehensively when compared to material flows) They relate
1 httpwwwoneplanetnetworkorgresource10yfp-indicators-success
to two important policy areas of resource efficiency and climate mitigation identified as priorities
by many governments including the G7 and G20
Further categories to be integrated in future version of the SCP-HAT could include for example
Water use and water scarcity
Primary energy
Land transformation
Mercury emissions
Solid waste
Social life-cycle impacts (hazardous or child labour corruption etc)
Geographical and IndustryProduct coverage
The aim of SCP-HAT is to cover all countries in the world including those with relatively short
history of engaging more actively in policy making around policy areas such as SCP the SDGs
green economy etc The geographical coverage of SCP-HAT is based on the official list of UN
Member States2 but constrained by the country resolution of the databases utilised This choice
does not imply any political judgment All databases utilised in the SCP-HAT have their own
territorial definitions which do not always coincide especially regarding to former colonies
territories with independence partially recognized etc In total the SCP-HAT includes 171 UN
state members for which data are available in all databases There are some lsquospecial casesrsquo
Sudan includes South Sudan from 1990 to 2011 while Ethiopia includes Eritrea from 1990 to
1992 The full list is provided in Annex II The unified sector aggregation applied encompasses
26 economic sectorsproduct categories which is the level of detail of the underlying input-
output model (see below) A complete list can be found in the Annex III
3 Data sources
Multi-Regional Input-Output
There are a number of global input-output models available which allow for comprehensive EE-
MRIO modelling Depending on the political or scientific question to be answered they have their
strengths and weaknesses The input-output core applied in the SCP-HAT is the lsquoEorarsquo database
(Lenzen et al 2013 2012) Its major advantage in comparison to other available MRIO
databases is its geographical coverage of 188 single countries and thus the possibility to perform
nation-specific analysis for almost any country in the world Two Eora version are available the
2 httpwwwunorgenmember-states
Full Eora and the Eora26 The difference between them resides in the sectoral classification The
former uses the original sector disaggregation of the IO-tables as provided by the original source
Here the resolution varies between 26 and a few hundred sectors The latter applies a
harmonised 26sectors disaggregation for all countries For SCP-HAT we apply the Eora26 Even
though Full Eora can be considered more accurate using Eora26 avoids possible computational
problems since memory needs and server space would be significantly lower Time series are
available for 1990 to 2015 which is hence also the time span for the SCP-HAT
GHG emissions and Climate Change (Short-Term and Long-Term)
The UNEP LCI guidance for LCIA indicators makes an interim recommendation for considering
two impact categories for climate change short-term related to the rate of temperature change
and long-term related to the long-term temperature rise (UNEP 2016) The indicators
recommended for short-term and long-term respectively are Global Warming Potential 100
(GWP100) and Global Temperature change Potential (GTP100) at 100 years horizon The
corresponding characterization factors provided by UNEP are applied to GHG emissions data
with impact factors for 24 separate emissions including differentiation of fossil- and biogenic
methane (Full list of GWP and GTP factors in Annex IV) Near-term climate forcing gases are
excluded as the UNEP LCI guidance recommends those for sensitivity analysis only
Two sources are employed for compiling the SCP-HATrsquos GHG emissions input data The main
dataset was the PRIMAP-hist (PRIMAP ndash Potsdam Realtime Integrated Model for Probabilistic
Assessment of Emissions Paths) developed by the Potsdam Institute for Climate Impact Research
(Guumltschow et al 2019 2016) PRIMAP-hist was selected because of its coverage of long time
series and because it integrates other popular global GHG datasets (eg British Petroleum
Review of World Energy (BP 2014) Carbon Dioxide Information Analysis Center fossil fuel and
industrial CO2 emissions dataset (Boden et al 2015) the EDGAR dataset (Janssens-Maenhout
et al 2019) It includes emissions for the main Kyoto greenhouse gases carbon dioxide (CO2)
methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons
(PFCs)sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3) for the period of 1850 to 2016
The country detail is high including almost all countries considered in the SCP-HAT
The PRIMAP-hist sector categorization is based on the main Intergovernmental Panel on Climate
Change (IPCC) 2006 categories It has been analysed in the literature that too poor sector
resolution in the environmental extension of EE-MRIO models can cause aggregation errors
(Steen-Olsen et al 2014 Su et al 2010) and inclusion of external data for further
disaggregation is recommended (Lenzen 2011) To prevent this aggregation bias the PRIMAP-
hist data is further disaggregated using GHG emissions shares from the EDGAR database which
is maintained by the European Commission Joint Research Centre (JRC) and the Netherlands
Environmental Assessment Agency (PBL) (Janssens-Maenhout et al 2019 Olivier and Janssens-
Maenhout 2012) The shares of the different IPCC categories contributing to the total as reported
by EDGAR were applied to the totals published by PRIMAP-hist and used for SCP-HAT Three
specific EDGAR datasets are utilized the Edgar version 432 the EDGAR version 42 Fast Track
(FT) 2010 and the EDGAR version 42 For CO2 CH4 and N2O and the whole period Edgar
version 432 was used For SF6 the Edgar version 42 was used for the period 1990-1999 and
the Edgar version 42 FT for the period 2000-2010 Edgar shares from version 42 were adjusted
using the same approach as FAOSTAT for compiling their ldquoEmissions by sectorrdquo3 dataset For
HFCs and PFCs the EDGAR version 42 FT 2010 was used and shares from 2000 were assumed
as being equal for the period 1990-1999 For HFCs PFCs and SF6 shares for 2010 from Edgar
FT 2010 were applied for the disaggregation of the years 2011 to 2015 After the disaggregation
of the PRIMAP-hist data the IPCC 2006 categories were allocated to one or more sectors of the
SCP-HAT (ie Eora 26 sectors) The IPCC 2006 sector classification in the SCP-HAT and the
correspondence to the SCP-HAT sectors is provided in Annex V For those categories allocated
to more than one sector the emissions were disaggregated according to the relationship of the
total output of the sectors
Lastly emissions from road transportation from industries and households are recorded together
in PRIMAP-hits and EDGAR which need to be disaggregated for a finer analysis in the SCP-HAT
This was done applying the shares of different industries and households in the overall use of
the category lsquoPetroleum Chemical and Non-Metallic Mineral Productsrsquo as provided in Eora
Raw material use and mineral and fossil resource scarcity
For physical data for raw material extraction data from UN IRP Global Material Flows Database
(UN IRP 2017) are used It includes 13 aggregated raw material categories compiled following
lsquoeconomy-wide material flow accountingrsquo principles (Eurostat 2013 OECD 2008) for 192
countries including most of the countries of the SCP-HAT A full list of the raw material extraction
categories can be found in Annex VI National material extraction is allocated to the three
extractive sectors contained in the Eora26 sector classification ndash lsquoagriculturersquo lsquofishingrsquo and
lsquomining and quarryingrsquo While such a high aggregation of extractive sectors can result in a
distortion of the overall results (de Koning et al 2015 Pintildeero et al 2014) an improvement by
means for instance of allocating the extractions to intermediate users (Giljum et al 2017
Schaffartzik et al 2013 Wiebe et al 2012) ndash eg iron from mining to the steel industry ndash is
implemented in some cases The resulting allocation is sometimes referred as lsquouse extensionrsquo in
contrast to the most common lsquosupply extensionrsquo (further details in Annex I)
3 See httpwwwfaoorgfaostatendataEM
Raw material extraction for abiotic materials is translated into impacts by using the mineral and
fossil resource scarcity characterization factors from the Dutch National Institute for Public Health
and the Environment (RIVM) (Huijbregts et al 2016) The midpoint indicator (ie focussing on
intermediate stage along the impact pathway) for fossil resource scarcity is defined as the ratio
between the energy content of fossil resource x and the energy content of crude oil The unit of
this indicator is kg oil-equivalent and it simply reflects the energy content compared to a kilogram
of oil The characterization method for mineral resource scarcity is Surplus Ore Potential which
expresses the average extra amount of ore to be produced in the future due to the extraction of
1 kg of a mineral resource x In other words this reflects the decrease in ore grade of remaining
reserves The indicator is expressed relative to copper in units of kg Cu-equivalent The
ldquohierarchistrdquo version of this indicator is applied which means that future production is chosen to
be the ultimate recoverable resource For more details see RIVM (Huijbregts et al 2016) An
unweighted average characterization factor for the group of ldquoOther metalsrdquo was derived using
the 25 materials listed in that category in the Global Material Flows Database The resulting
factor was dominated by caesium which is probably higher than realistic In version 11 the
characterization factor for the group of ldquoOther metalsrdquo was updated by using a global-production-
weighted average (averaged over the years 2012-2014 as data for some metals are only
available after 2012) This resulted in a significant reduction of the factor with the main
contributors being mercury magnesium zirconium and hafnium
Land use and potential species loss from land use
The UNEP LCI guidance for LCIA indicators makes an interim recommendation (see UNEP 2016)
for characterization of biodiversity impacts of land use discerning occupation and
transformation based on the method developed by Chaudhary et al (2015) In this first version
of the SCP-HAT only land occupation is included and modelling of land transformation is left for
future tool developments To allow for the application of the recommended characterization
factors inventory data is required for land occupation (m2a) for six land use classes - Annual
crops Permanent crops Pasture Extensive forestry Intensive forestry Urban Annex VII shows
sector correspondence for the land use categories in the SCP-HAT Land use for crops and
pasture is allocated partly to the agriculture sector and partly to final demand The allocation to
final demand is made based on data on subsistence and low-input crop farming derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) For details on the
allocation methodology see Annex XXI Land use for intensive forestry is allocated to the wood
and paper industry (ie allocation to first intermediate users see Annex I) Land use for
extensive forestry is allocated partly to the wood and paper industry and partly to final demand
based on domestic wood fuel production and consumption statistics For details on the allocation
methodology see Annex XXI
Land use for other industrial activities than agriculture or forestry (eg mining) is not covered
From version v11 onwards built-up land is allocated directly to final demand and estimated
using OECD land use statistics (OECD 2018)
The definition of the two forestry land use classes used for the impact characterization is i)
Intensive Forest forests with extractive use with either even-aged stands and clear-cut
patches or less than three naturally occurring species at plantingseeding and ii) Extensive
Forests forests with extractive use and associated disturbance like hunting and selective
logging where timber extraction is followed by re-growth including at least three naturally
occurring tree species For the latter alternative uses to wood and paper eg recreation
hunting etc are not considered
Land use data for Annual crops Permanent crops and Pasture are gathered from FAOSTATrsquos
databases for the analogous categories arable land permanent crops and permanent meadows
and pastures (Food and Agriculture Organization of the United Nations 2018) Table 1 shows
data sources and model description for Extensive and Intensive Forestry
Following UNEPrsquos recommendations country-level average characterization factors for global
species loss from Chaudhary et al (2015) are used in the SCP-HAT aggregated over five taxa
(mammals reptiles birds amphibians and vascular plants) for each of the six land use
categories The unit of this indicator is PDFyear which stands for the Potentially Disappeared
Fraction of species for the duration of a year Land use impact modelling assumes that once an
activity (land use) stops the system will slowly return to the natural state The indicator
therefore does not reflect full extinction of species but a temporary decline in biodiversity

Air pollution and health impacts
Many emissions contribute to air pollution via a variety of mechanisms SCP-HAT focuses on air
pollution via particulate matter (PM) which is caused by emissions of PM itself as well as by
emissions of NH3 NOx and SO2 which form so-called secondary PM via chemical reactions The
UNEP LCI guidance for LCIA indicators (UNEP 2016) recommends the use of characterization
factors at end-point reflecting damages to human health expressed in Disability-Adjusted Life
Years (DALY) The recommended approach for calculating DALY impact factors is via emission
source archetypes but this could not be implemented at the global highly aggregated scale of
emissions data used in SCP-HAT The tool therefore uses DALY impact factors from RIVM
(Huijbregts et al 2016) which reflect country-averaged DALY impacts per unit of emission for
each of the four substances (PM25 NH3 SO2 NOx) No differentiation is made by emission source
type at this stage A recent set of new effect factors (Fantke et al 2019) is still only available
at country level without additional distinction of emission source type
The emissions data are taken from the EDGAR database (v432) This database covers all
countries and years up to and including 2012 For emissions of primary PM25 fossil and biogenic
sources are distinguished There is no difference in impact (DALYkg emitted) between those
two categories The data are extrapolated to 2013 and 2015 using GHG emissions trends with a
fixed emission ratio based on 2012 data As shown in Crippa et al (2018) emission ratios of air
pollutants to carbon dioxide have steadily decreased since 1970 but have been relatively stable
since around 2010 especially for NOx and SO2 More specifically PM25 fossil NOx and SO2 are
projected using CO2 emissions trends while CH4 and N2O (in CO2 eq) are used for PM25 bio and
NH3 During data processing it was found that this approach is not satisfactory for NH3 emissions
from agriculture and results are of especially high uncertainty for this category Thus future
improvements should prioritize this specific flow
Socio-economic data
The SCP-HAT includes a set of basic socioeconomic data which mainly serves for the estimation
of relative performance indicators of economies and industries eg carbon per unit of economic
output In the following the data sources used are listed
Population The World Bank Group
GDP The World Bank Group
Value added Eora database
Output Eora database
Employment per sector International Labour Organization
Country groups The World Bank Group
Government and private final consumption Eora database
HDI United Nations Development Programme
Country groups The World Bank Group
Employment by sector and gender is compiled from the ILO (International Labour Organization
2018) The dataset on employment by gender and sector includes only 14 sectors
Disaggregation is done using compensation to employees in Eora as proxy (ie it is assumed
same retribution between sectors belonging to an ILO category)
4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10

supported in v10 Module 3 National Data System
Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

data on transactions among economic sectors and final consumers of different countries Hence
each monetary flow is associated with a physical equivalent (mathematical details in Annex I)
By that means double counting is avoided as the specific supply chains be they national or
international can be clearly identified form their start at resource extraction until the point of
final demand
This approach allows tracing all the pressures and impacts occurring at the different stages of even very complex supply chains and allocating them to the country of final consumption or sectoral production Hence domestic pressures (national environment) are linked to foreign consumption (countries A to F in
Figure 1Figure 1) and foreign pressures to domestic consumption This allows to analyse both
the domestic situation (ldquodomestic productionrdquo) with regard to prevailing pressures and impacts
and the role a country plays as global consumer (ldquoconsumption footprintrdquo) where the focus is
set on pressures and impacts occurring along the supply chains of consumed products
Figure 1 The basic concept of SCP-HAT
This type of analysis is used to identify hotspots of sustainable consumption and production and
opportunities for action (1) pressure or impact categories where immediate action is needed on
the national level and (2) sectors or consumption areas where the pressures or impacts caused
directly or indirectly are specifically high and action is required
In general the consumption footprint of a country is calculated by adding the pressures and
impacts related to imports to those occurring domestically and subtracting those related to the
exports It is important to note the differences between approaches based upon EE-MRIO and
those using coefficients to estimate the indirect trade flows of pressures and impacts and the
consumption footprint of a country
- Coefficient approaches calculate the total environmental pressures or impacts associated
with final consumption by accounting for physical in- and out-flows of a country and
considering the environmental intensity of the traded commodities along the whole
production chain They apply intensity coefficients ndash or ldquocradle-to-productrdquo coefficients ndash
to the specific traded products and activities Here the consumption footprint of a country
is calculated by adding the pressures and impacts related to all imports to those occurring
domestically and subtracting those related to all the exports
Coefficient approaches apply the concept of ldquoapparent consumptionrdquo ie they cannot
specify whether a certain environmental pressure or impact is associated with
intermediate production or consumed by the final consumer Accordingly trade balances
are calculated in gross terms ie considering both intermediate and final trade products
(see above) Though conceptually feasible in practice it is not possible to separate eg
private consumption from government consumption Finally often so-called ldquotruncation
errorsrdquo are produced as the indirect flows are not traced along the entire industrial supply
chains The most important advantage of coefficient-based approaches is the high level of
detail and transparency which can be applied in footprint-oriented indicator calculations
- As explained above input-output analysis allows tracing monetary flows and embodied
environmental factors from its origin (eg raw material extraction) to the final consumption
of the respective products The so-called ldquoLeontief inverserdquo a matrix generated from an
input-output table (see Annex I) shows for each commodity or industry represented in
the model all direct and indirect inputs and related environmental pressures and impacts
required along the complete supply chain Doing the calculation for all product groups all
environmental pressures and impacts needed to satisfy final demand of a country can be
quantified
A major advantage of input-output based approaches is that input-output tables
disaggregate a large number of different product groups and industries as well as final
demand categories (eg private consumption government consumption investments
etc) They allow calculating the footprints for all products and all sectors also those with
very complex supply chains and thus avoid truncation errors (see above) Finally the
countries of origin of a countryrsquos consumption footprint can be identified as well as the
countries of destination of the domestic environmental pressures and impacts
Consequently in contrast to coefficient-based approaches analyses of indirect trade flows
are done from the perspective of linking source countries with final demand in the
destination countries Hence trade analyses in Module 1 and 2 of SCP-HAT have to be
understood before this background import flows into a country of interest will only include
those pressures and impacts occurring abroad which contribute to the countryrsquos final
demand Export flows incorporate only the pressures and impacts which occur
domestically and contribute to final demand abroad Consequently flows which ldquopass
throughrdquo the country via imports and re-exports are not accounted for
When comparing results for a country of interest which stem from MRIO-based and
coefficient-based approaches conceptually the numbers for the consumption footprint can
be directly compared while those for trade flows cannot
EE-MRIO is complemented by impact assessment for the calculation of certain environmental
impact variables (using Life Cycle Impact Assessment (LCIA) characterization factors) While
environmental accounts used in EE-MRIO provide data on domestic resource use in the countries
around the world LCIA ldquotranslatesrdquo these amounts into environmental impacts such as
biodiversity loss from land use or resource depletion related to raw material use This
methodological step is realised in accordance with the LCIA guidelines set by the United Nations
Environment Programme (UNEP 2016)
Pressure and impact categories
Ideally the SCP-HAT tool would cover all indicators included in the 10-year framework of
programmes on sustainable consumption and production patterns (10YFP) Evaluation and
Monitoring Framework1 ie material use waste water use energy use GHG emissions air soil
and water pollutants biodiversity conservation and land use and human well-being indicators
related to gender decent work and health However for the development of the 2018 version
of the tool a first selection of highly relevant pressure and impact categories are implemented
Environmental pressures
o Raw material use
o Land use (occupation only)
o Emissions of greenhouse gases
o Emissions of particulate matter and precursors
Environmental impacts
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
The selection of a first set of pressures and impacts was guided by a set of criteria
Readiness of data availability
Relevance for SCP policy questions
Interrelatedness of pressures and impacts
Widely accepted impact characterization factors
Moreover the focus was set on an extensive coverage of related issues to be covered indirectly
with the selected domains For instance material flows include most energy carriers (and to a
large extend also cover energy) and allow for proxies for waste GHG emissions also have a large
overlap with energy use (more comprehensively when compared to material flows) They relate
1 httpwwwoneplanetnetworkorgresource10yfp-indicators-success
to two important policy areas of resource efficiency and climate mitigation identified as priorities
by many governments including the G7 and G20
Further categories to be integrated in future version of the SCP-HAT could include for example
Water use and water scarcity
Primary energy
Land transformation
Mercury emissions
Solid waste
Social life-cycle impacts (hazardous or child labour corruption etc)
Geographical and IndustryProduct coverage
The aim of SCP-HAT is to cover all countries in the world including those with relatively short
history of engaging more actively in policy making around policy areas such as SCP the SDGs
green economy etc The geographical coverage of SCP-HAT is based on the official list of UN
Member States2 but constrained by the country resolution of the databases utilised This choice
does not imply any political judgment All databases utilised in the SCP-HAT have their own
territorial definitions which do not always coincide especially regarding to former colonies
territories with independence partially recognized etc In total the SCP-HAT includes 171 UN
state members for which data are available in all databases There are some lsquospecial casesrsquo
Sudan includes South Sudan from 1990 to 2011 while Ethiopia includes Eritrea from 1990 to
1992 The full list is provided in Annex II The unified sector aggregation applied encompasses
26 economic sectorsproduct categories which is the level of detail of the underlying input-
output model (see below) A complete list can be found in the Annex III
3 Data sources
Multi-Regional Input-Output
There are a number of global input-output models available which allow for comprehensive EE-
MRIO modelling Depending on the political or scientific question to be answered they have their
strengths and weaknesses The input-output core applied in the SCP-HAT is the lsquoEorarsquo database
(Lenzen et al 2013 2012) Its major advantage in comparison to other available MRIO
databases is its geographical coverage of 188 single countries and thus the possibility to perform
nation-specific analysis for almost any country in the world Two Eora version are available the
2 httpwwwunorgenmember-states
Full Eora and the Eora26 The difference between them resides in the sectoral classification The
former uses the original sector disaggregation of the IO-tables as provided by the original source
Here the resolution varies between 26 and a few hundred sectors The latter applies a
harmonised 26sectors disaggregation for all countries For SCP-HAT we apply the Eora26 Even
though Full Eora can be considered more accurate using Eora26 avoids possible computational
problems since memory needs and server space would be significantly lower Time series are
available for 1990 to 2015 which is hence also the time span for the SCP-HAT
GHG emissions and Climate Change (Short-Term and Long-Term)
The UNEP LCI guidance for LCIA indicators makes an interim recommendation for considering
two impact categories for climate change short-term related to the rate of temperature change
and long-term related to the long-term temperature rise (UNEP 2016) The indicators
recommended for short-term and long-term respectively are Global Warming Potential 100
(GWP100) and Global Temperature change Potential (GTP100) at 100 years horizon The
corresponding characterization factors provided by UNEP are applied to GHG emissions data
with impact factors for 24 separate emissions including differentiation of fossil- and biogenic
methane (Full list of GWP and GTP factors in Annex IV) Near-term climate forcing gases are
excluded as the UNEP LCI guidance recommends those for sensitivity analysis only
Two sources are employed for compiling the SCP-HATrsquos GHG emissions input data The main
dataset was the PRIMAP-hist (PRIMAP ndash Potsdam Realtime Integrated Model for Probabilistic
Assessment of Emissions Paths) developed by the Potsdam Institute for Climate Impact Research
(Guumltschow et al 2019 2016) PRIMAP-hist was selected because of its coverage of long time
series and because it integrates other popular global GHG datasets (eg British Petroleum
Review of World Energy (BP 2014) Carbon Dioxide Information Analysis Center fossil fuel and
industrial CO2 emissions dataset (Boden et al 2015) the EDGAR dataset (Janssens-Maenhout
et al 2019) It includes emissions for the main Kyoto greenhouse gases carbon dioxide (CO2)
methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons
(PFCs)sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3) for the period of 1850 to 2016
The country detail is high including almost all countries considered in the SCP-HAT
The PRIMAP-hist sector categorization is based on the main Intergovernmental Panel on Climate
Change (IPCC) 2006 categories It has been analysed in the literature that too poor sector
resolution in the environmental extension of EE-MRIO models can cause aggregation errors
(Steen-Olsen et al 2014 Su et al 2010) and inclusion of external data for further
disaggregation is recommended (Lenzen 2011) To prevent this aggregation bias the PRIMAP-
hist data is further disaggregated using GHG emissions shares from the EDGAR database which
is maintained by the European Commission Joint Research Centre (JRC) and the Netherlands
Environmental Assessment Agency (PBL) (Janssens-Maenhout et al 2019 Olivier and Janssens-
Maenhout 2012) The shares of the different IPCC categories contributing to the total as reported
by EDGAR were applied to the totals published by PRIMAP-hist and used for SCP-HAT Three
specific EDGAR datasets are utilized the Edgar version 432 the EDGAR version 42 Fast Track
(FT) 2010 and the EDGAR version 42 For CO2 CH4 and N2O and the whole period Edgar
version 432 was used For SF6 the Edgar version 42 was used for the period 1990-1999 and
the Edgar version 42 FT for the period 2000-2010 Edgar shares from version 42 were adjusted
using the same approach as FAOSTAT for compiling their ldquoEmissions by sectorrdquo3 dataset For
HFCs and PFCs the EDGAR version 42 FT 2010 was used and shares from 2000 were assumed
as being equal for the period 1990-1999 For HFCs PFCs and SF6 shares for 2010 from Edgar
FT 2010 were applied for the disaggregation of the years 2011 to 2015 After the disaggregation
of the PRIMAP-hist data the IPCC 2006 categories were allocated to one or more sectors of the
SCP-HAT (ie Eora 26 sectors) The IPCC 2006 sector classification in the SCP-HAT and the
correspondence to the SCP-HAT sectors is provided in Annex V For those categories allocated
to more than one sector the emissions were disaggregated according to the relationship of the
total output of the sectors
Lastly emissions from road transportation from industries and households are recorded together
in PRIMAP-hits and EDGAR which need to be disaggregated for a finer analysis in the SCP-HAT
This was done applying the shares of different industries and households in the overall use of
the category lsquoPetroleum Chemical and Non-Metallic Mineral Productsrsquo as provided in Eora
Raw material use and mineral and fossil resource scarcity
For physical data for raw material extraction data from UN IRP Global Material Flows Database
(UN IRP 2017) are used It includes 13 aggregated raw material categories compiled following
lsquoeconomy-wide material flow accountingrsquo principles (Eurostat 2013 OECD 2008) for 192
countries including most of the countries of the SCP-HAT A full list of the raw material extraction
categories can be found in Annex VI National material extraction is allocated to the three
extractive sectors contained in the Eora26 sector classification ndash lsquoagriculturersquo lsquofishingrsquo and
lsquomining and quarryingrsquo While such a high aggregation of extractive sectors can result in a
distortion of the overall results (de Koning et al 2015 Pintildeero et al 2014) an improvement by
means for instance of allocating the extractions to intermediate users (Giljum et al 2017
Schaffartzik et al 2013 Wiebe et al 2012) ndash eg iron from mining to the steel industry ndash is
implemented in some cases The resulting allocation is sometimes referred as lsquouse extensionrsquo in
contrast to the most common lsquosupply extensionrsquo (further details in Annex I)
3 See httpwwwfaoorgfaostatendataEM
Raw material extraction for abiotic materials is translated into impacts by using the mineral and
fossil resource scarcity characterization factors from the Dutch National Institute for Public Health
and the Environment (RIVM) (Huijbregts et al 2016) The midpoint indicator (ie focussing on
intermediate stage along the impact pathway) for fossil resource scarcity is defined as the ratio
between the energy content of fossil resource x and the energy content of crude oil The unit of
this indicator is kg oil-equivalent and it simply reflects the energy content compared to a kilogram
of oil The characterization method for mineral resource scarcity is Surplus Ore Potential which
expresses the average extra amount of ore to be produced in the future due to the extraction of
1 kg of a mineral resource x In other words this reflects the decrease in ore grade of remaining
reserves The indicator is expressed relative to copper in units of kg Cu-equivalent The
ldquohierarchistrdquo version of this indicator is applied which means that future production is chosen to
be the ultimate recoverable resource For more details see RIVM (Huijbregts et al 2016) An
unweighted average characterization factor for the group of ldquoOther metalsrdquo was derived using
the 25 materials listed in that category in the Global Material Flows Database The resulting
factor was dominated by caesium which is probably higher than realistic In version 11 the
characterization factor for the group of ldquoOther metalsrdquo was updated by using a global-production-
weighted average (averaged over the years 2012-2014 as data for some metals are only
available after 2012) This resulted in a significant reduction of the factor with the main
contributors being mercury magnesium zirconium and hafnium
Land use and potential species loss from land use
The UNEP LCI guidance for LCIA indicators makes an interim recommendation (see UNEP 2016)
for characterization of biodiversity impacts of land use discerning occupation and
transformation based on the method developed by Chaudhary et al (2015) In this first version
of the SCP-HAT only land occupation is included and modelling of land transformation is left for
future tool developments To allow for the application of the recommended characterization
factors inventory data is required for land occupation (m2a) for six land use classes - Annual
crops Permanent crops Pasture Extensive forestry Intensive forestry Urban Annex VII shows
sector correspondence for the land use categories in the SCP-HAT Land use for crops and
pasture is allocated partly to the agriculture sector and partly to final demand The allocation to
final demand is made based on data on subsistence and low-input crop farming derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) For details on the
allocation methodology see Annex XXI Land use for intensive forestry is allocated to the wood
and paper industry (ie allocation to first intermediate users see Annex I) Land use for
extensive forestry is allocated partly to the wood and paper industry and partly to final demand
based on domestic wood fuel production and consumption statistics For details on the allocation
methodology see Annex XXI
Land use for other industrial activities than agriculture or forestry (eg mining) is not covered
From version v11 onwards built-up land is allocated directly to final demand and estimated
using OECD land use statistics (OECD 2018)
The definition of the two forestry land use classes used for the impact characterization is i)
Intensive Forest forests with extractive use with either even-aged stands and clear-cut
patches or less than three naturally occurring species at plantingseeding and ii) Extensive
Forests forests with extractive use and associated disturbance like hunting and selective
logging where timber extraction is followed by re-growth including at least three naturally
occurring tree species For the latter alternative uses to wood and paper eg recreation
hunting etc are not considered
Land use data for Annual crops Permanent crops and Pasture are gathered from FAOSTATrsquos
databases for the analogous categories arable land permanent crops and permanent meadows
and pastures (Food and Agriculture Organization of the United Nations 2018) Table 1 shows
data sources and model description for Extensive and Intensive Forestry
Following UNEPrsquos recommendations country-level average characterization factors for global
species loss from Chaudhary et al (2015) are used in the SCP-HAT aggregated over five taxa
(mammals reptiles birds amphibians and vascular plants) for each of the six land use
categories The unit of this indicator is PDFyear which stands for the Potentially Disappeared
Fraction of species for the duration of a year Land use impact modelling assumes that once an
activity (land use) stops the system will slowly return to the natural state The indicator
therefore does not reflect full extinction of species but a temporary decline in biodiversity

Air pollution and health impacts
Many emissions contribute to air pollution via a variety of mechanisms SCP-HAT focuses on air
pollution via particulate matter (PM) which is caused by emissions of PM itself as well as by
emissions of NH3 NOx and SO2 which form so-called secondary PM via chemical reactions The
UNEP LCI guidance for LCIA indicators (UNEP 2016) recommends the use of characterization
factors at end-point reflecting damages to human health expressed in Disability-Adjusted Life
Years (DALY) The recommended approach for calculating DALY impact factors is via emission
source archetypes but this could not be implemented at the global highly aggregated scale of
emissions data used in SCP-HAT The tool therefore uses DALY impact factors from RIVM
(Huijbregts et al 2016) which reflect country-averaged DALY impacts per unit of emission for
each of the four substances (PM25 NH3 SO2 NOx) No differentiation is made by emission source
type at this stage A recent set of new effect factors (Fantke et al 2019) is still only available
at country level without additional distinction of emission source type
The emissions data are taken from the EDGAR database (v432) This database covers all
countries and years up to and including 2012 For emissions of primary PM25 fossil and biogenic
sources are distinguished There is no difference in impact (DALYkg emitted) between those
two categories The data are extrapolated to 2013 and 2015 using GHG emissions trends with a
fixed emission ratio based on 2012 data As shown in Crippa et al (2018) emission ratios of air
pollutants to carbon dioxide have steadily decreased since 1970 but have been relatively stable
since around 2010 especially for NOx and SO2 More specifically PM25 fossil NOx and SO2 are
projected using CO2 emissions trends while CH4 and N2O (in CO2 eq) are used for PM25 bio and
NH3 During data processing it was found that this approach is not satisfactory for NH3 emissions
from agriculture and results are of especially high uncertainty for this category Thus future
improvements should prioritize this specific flow
Socio-economic data
The SCP-HAT includes a set of basic socioeconomic data which mainly serves for the estimation
of relative performance indicators of economies and industries eg carbon per unit of economic
output In the following the data sources used are listed
Population The World Bank Group
GDP The World Bank Group
Value added Eora database
Output Eora database
Employment per sector International Labour Organization
Country groups The World Bank Group
Government and private final consumption Eora database
HDI United Nations Development Programme
Country groups The World Bank Group
Employment by sector and gender is compiled from the ILO (International Labour Organization
2018) The dataset on employment by gender and sector includes only 14 sectors
Disaggregation is done using compensation to employees in Eora as proxy (ie it is assumed
same retribution between sectors belonging to an ILO category)
4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Figure 1 The basic concept of SCP-HAT
This type of analysis is used to identify hotspots of sustainable consumption and production and
opportunities for action (1) pressure or impact categories where immediate action is needed on
the national level and (2) sectors or consumption areas where the pressures or impacts caused
directly or indirectly are specifically high and action is required
In general the consumption footprint of a country is calculated by adding the pressures and
impacts related to imports to those occurring domestically and subtracting those related to the
exports It is important to note the differences between approaches based upon EE-MRIO and
those using coefficients to estimate the indirect trade flows of pressures and impacts and the
consumption footprint of a country
- Coefficient approaches calculate the total environmental pressures or impacts associated
with final consumption by accounting for physical in- and out-flows of a country and
considering the environmental intensity of the traded commodities along the whole
production chain They apply intensity coefficients ndash or ldquocradle-to-productrdquo coefficients ndash
to the specific traded products and activities Here the consumption footprint of a country
is calculated by adding the pressures and impacts related to all imports to those occurring
domestically and subtracting those related to all the exports
Coefficient approaches apply the concept of ldquoapparent consumptionrdquo ie they cannot
specify whether a certain environmental pressure or impact is associated with
intermediate production or consumed by the final consumer Accordingly trade balances
are calculated in gross terms ie considering both intermediate and final trade products
(see above) Though conceptually feasible in practice it is not possible to separate eg
private consumption from government consumption Finally often so-called ldquotruncation
errorsrdquo are produced as the indirect flows are not traced along the entire industrial supply
chains The most important advantage of coefficient-based approaches is the high level of
detail and transparency which can be applied in footprint-oriented indicator calculations
- As explained above input-output analysis allows tracing monetary flows and embodied
environmental factors from its origin (eg raw material extraction) to the final consumption
of the respective products The so-called ldquoLeontief inverserdquo a matrix generated from an
input-output table (see Annex I) shows for each commodity or industry represented in
the model all direct and indirect inputs and related environmental pressures and impacts
required along the complete supply chain Doing the calculation for all product groups all
environmental pressures and impacts needed to satisfy final demand of a country can be
quantified
A major advantage of input-output based approaches is that input-output tables
disaggregate a large number of different product groups and industries as well as final
demand categories (eg private consumption government consumption investments
etc) They allow calculating the footprints for all products and all sectors also those with
very complex supply chains and thus avoid truncation errors (see above) Finally the
countries of origin of a countryrsquos consumption footprint can be identified as well as the
countries of destination of the domestic environmental pressures and impacts
Consequently in contrast to coefficient-based approaches analyses of indirect trade flows
are done from the perspective of linking source countries with final demand in the
destination countries Hence trade analyses in Module 1 and 2 of SCP-HAT have to be
understood before this background import flows into a country of interest will only include
those pressures and impacts occurring abroad which contribute to the countryrsquos final
demand Export flows incorporate only the pressures and impacts which occur
domestically and contribute to final demand abroad Consequently flows which ldquopass
throughrdquo the country via imports and re-exports are not accounted for
When comparing results for a country of interest which stem from MRIO-based and
coefficient-based approaches conceptually the numbers for the consumption footprint can
be directly compared while those for trade flows cannot
EE-MRIO is complemented by impact assessment for the calculation of certain environmental
impact variables (using Life Cycle Impact Assessment (LCIA) characterization factors) While
environmental accounts used in EE-MRIO provide data on domestic resource use in the countries
around the world LCIA ldquotranslatesrdquo these amounts into environmental impacts such as
biodiversity loss from land use or resource depletion related to raw material use This
methodological step is realised in accordance with the LCIA guidelines set by the United Nations
Environment Programme (UNEP 2016)
Pressure and impact categories
Ideally the SCP-HAT tool would cover all indicators included in the 10-year framework of
programmes on sustainable consumption and production patterns (10YFP) Evaluation and
Monitoring Framework1 ie material use waste water use energy use GHG emissions air soil
and water pollutants biodiversity conservation and land use and human well-being indicators
related to gender decent work and health However for the development of the 2018 version
of the tool a first selection of highly relevant pressure and impact categories are implemented
Environmental pressures
o Raw material use
o Land use (occupation only)
o Emissions of greenhouse gases
o Emissions of particulate matter and precursors
Environmental impacts
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
The selection of a first set of pressures and impacts was guided by a set of criteria
Readiness of data availability
Relevance for SCP policy questions
Interrelatedness of pressures and impacts
Widely accepted impact characterization factors
Moreover the focus was set on an extensive coverage of related issues to be covered indirectly
with the selected domains For instance material flows include most energy carriers (and to a
large extend also cover energy) and allow for proxies for waste GHG emissions also have a large
overlap with energy use (more comprehensively when compared to material flows) They relate
1 httpwwwoneplanetnetworkorgresource10yfp-indicators-success
to two important policy areas of resource efficiency and climate mitigation identified as priorities
by many governments including the G7 and G20
Further categories to be integrated in future version of the SCP-HAT could include for example
Water use and water scarcity
Primary energy
Land transformation
Mercury emissions
Solid waste
Social life-cycle impacts (hazardous or child labour corruption etc)
Geographical and IndustryProduct coverage
The aim of SCP-HAT is to cover all countries in the world including those with relatively short
history of engaging more actively in policy making around policy areas such as SCP the SDGs
green economy etc The geographical coverage of SCP-HAT is based on the official list of UN
Member States2 but constrained by the country resolution of the databases utilised This choice
does not imply any political judgment All databases utilised in the SCP-HAT have their own
territorial definitions which do not always coincide especially regarding to former colonies
territories with independence partially recognized etc In total the SCP-HAT includes 171 UN
state members for which data are available in all databases There are some lsquospecial casesrsquo
Sudan includes South Sudan from 1990 to 2011 while Ethiopia includes Eritrea from 1990 to
1992 The full list is provided in Annex II The unified sector aggregation applied encompasses
26 economic sectorsproduct categories which is the level of detail of the underlying input-
output model (see below) A complete list can be found in the Annex III
3 Data sources
Multi-Regional Input-Output
There are a number of global input-output models available which allow for comprehensive EE-
MRIO modelling Depending on the political or scientific question to be answered they have their
strengths and weaknesses The input-output core applied in the SCP-HAT is the lsquoEorarsquo database
(Lenzen et al 2013 2012) Its major advantage in comparison to other available MRIO
databases is its geographical coverage of 188 single countries and thus the possibility to perform
nation-specific analysis for almost any country in the world Two Eora version are available the
2 httpwwwunorgenmember-states
Full Eora and the Eora26 The difference between them resides in the sectoral classification The
former uses the original sector disaggregation of the IO-tables as provided by the original source
Here the resolution varies between 26 and a few hundred sectors The latter applies a
harmonised 26sectors disaggregation for all countries For SCP-HAT we apply the Eora26 Even
though Full Eora can be considered more accurate using Eora26 avoids possible computational
problems since memory needs and server space would be significantly lower Time series are
available for 1990 to 2015 which is hence also the time span for the SCP-HAT
GHG emissions and Climate Change (Short-Term and Long-Term)
The UNEP LCI guidance for LCIA indicators makes an interim recommendation for considering
two impact categories for climate change short-term related to the rate of temperature change
and long-term related to the long-term temperature rise (UNEP 2016) The indicators
recommended for short-term and long-term respectively are Global Warming Potential 100
(GWP100) and Global Temperature change Potential (GTP100) at 100 years horizon The
corresponding characterization factors provided by UNEP are applied to GHG emissions data
with impact factors for 24 separate emissions including differentiation of fossil- and biogenic
methane (Full list of GWP and GTP factors in Annex IV) Near-term climate forcing gases are
excluded as the UNEP LCI guidance recommends those for sensitivity analysis only
Two sources are employed for compiling the SCP-HATrsquos GHG emissions input data The main
dataset was the PRIMAP-hist (PRIMAP ndash Potsdam Realtime Integrated Model for Probabilistic
Assessment of Emissions Paths) developed by the Potsdam Institute for Climate Impact Research
(Guumltschow et al 2019 2016) PRIMAP-hist was selected because of its coverage of long time
series and because it integrates other popular global GHG datasets (eg British Petroleum
Review of World Energy (BP 2014) Carbon Dioxide Information Analysis Center fossil fuel and
industrial CO2 emissions dataset (Boden et al 2015) the EDGAR dataset (Janssens-Maenhout
et al 2019) It includes emissions for the main Kyoto greenhouse gases carbon dioxide (CO2)
methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons
(PFCs)sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3) for the period of 1850 to 2016
The country detail is high including almost all countries considered in the SCP-HAT
The PRIMAP-hist sector categorization is based on the main Intergovernmental Panel on Climate
Change (IPCC) 2006 categories It has been analysed in the literature that too poor sector
resolution in the environmental extension of EE-MRIO models can cause aggregation errors
(Steen-Olsen et al 2014 Su et al 2010) and inclusion of external data for further
disaggregation is recommended (Lenzen 2011) To prevent this aggregation bias the PRIMAP-
hist data is further disaggregated using GHG emissions shares from the EDGAR database which
is maintained by the European Commission Joint Research Centre (JRC) and the Netherlands
Environmental Assessment Agency (PBL) (Janssens-Maenhout et al 2019 Olivier and Janssens-
Maenhout 2012) The shares of the different IPCC categories contributing to the total as reported
by EDGAR were applied to the totals published by PRIMAP-hist and used for SCP-HAT Three
specific EDGAR datasets are utilized the Edgar version 432 the EDGAR version 42 Fast Track
(FT) 2010 and the EDGAR version 42 For CO2 CH4 and N2O and the whole period Edgar
version 432 was used For SF6 the Edgar version 42 was used for the period 1990-1999 and
the Edgar version 42 FT for the period 2000-2010 Edgar shares from version 42 were adjusted
using the same approach as FAOSTAT for compiling their ldquoEmissions by sectorrdquo3 dataset For
HFCs and PFCs the EDGAR version 42 FT 2010 was used and shares from 2000 were assumed
as being equal for the period 1990-1999 For HFCs PFCs and SF6 shares for 2010 from Edgar
FT 2010 were applied for the disaggregation of the years 2011 to 2015 After the disaggregation
of the PRIMAP-hist data the IPCC 2006 categories were allocated to one or more sectors of the
SCP-HAT (ie Eora 26 sectors) The IPCC 2006 sector classification in the SCP-HAT and the
correspondence to the SCP-HAT sectors is provided in Annex V For those categories allocated
to more than one sector the emissions were disaggregated according to the relationship of the
total output of the sectors
Lastly emissions from road transportation from industries and households are recorded together
in PRIMAP-hits and EDGAR which need to be disaggregated for a finer analysis in the SCP-HAT
This was done applying the shares of different industries and households in the overall use of
the category lsquoPetroleum Chemical and Non-Metallic Mineral Productsrsquo as provided in Eora
Raw material use and mineral and fossil resource scarcity
For physical data for raw material extraction data from UN IRP Global Material Flows Database
(UN IRP 2017) are used It includes 13 aggregated raw material categories compiled following
lsquoeconomy-wide material flow accountingrsquo principles (Eurostat 2013 OECD 2008) for 192
countries including most of the countries of the SCP-HAT A full list of the raw material extraction
categories can be found in Annex VI National material extraction is allocated to the three
extractive sectors contained in the Eora26 sector classification ndash lsquoagriculturersquo lsquofishingrsquo and
lsquomining and quarryingrsquo While such a high aggregation of extractive sectors can result in a
distortion of the overall results (de Koning et al 2015 Pintildeero et al 2014) an improvement by
means for instance of allocating the extractions to intermediate users (Giljum et al 2017
Schaffartzik et al 2013 Wiebe et al 2012) ndash eg iron from mining to the steel industry ndash is
implemented in some cases The resulting allocation is sometimes referred as lsquouse extensionrsquo in
contrast to the most common lsquosupply extensionrsquo (further details in Annex I)
3 See httpwwwfaoorgfaostatendataEM
Raw material extraction for abiotic materials is translated into impacts by using the mineral and
fossil resource scarcity characterization factors from the Dutch National Institute for Public Health
and the Environment (RIVM) (Huijbregts et al 2016) The midpoint indicator (ie focussing on
intermediate stage along the impact pathway) for fossil resource scarcity is defined as the ratio
between the energy content of fossil resource x and the energy content of crude oil The unit of
this indicator is kg oil-equivalent and it simply reflects the energy content compared to a kilogram
of oil The characterization method for mineral resource scarcity is Surplus Ore Potential which
expresses the average extra amount of ore to be produced in the future due to the extraction of
1 kg of a mineral resource x In other words this reflects the decrease in ore grade of remaining
reserves The indicator is expressed relative to copper in units of kg Cu-equivalent The
ldquohierarchistrdquo version of this indicator is applied which means that future production is chosen to
be the ultimate recoverable resource For more details see RIVM (Huijbregts et al 2016) An
unweighted average characterization factor for the group of ldquoOther metalsrdquo was derived using
the 25 materials listed in that category in the Global Material Flows Database The resulting
factor was dominated by caesium which is probably higher than realistic In version 11 the
characterization factor for the group of ldquoOther metalsrdquo was updated by using a global-production-
weighted average (averaged over the years 2012-2014 as data for some metals are only
available after 2012) This resulted in a significant reduction of the factor with the main
contributors being mercury magnesium zirconium and hafnium
Land use and potential species loss from land use
The UNEP LCI guidance for LCIA indicators makes an interim recommendation (see UNEP 2016)
for characterization of biodiversity impacts of land use discerning occupation and
transformation based on the method developed by Chaudhary et al (2015) In this first version
of the SCP-HAT only land occupation is included and modelling of land transformation is left for
future tool developments To allow for the application of the recommended characterization
factors inventory data is required for land occupation (m2a) for six land use classes - Annual
crops Permanent crops Pasture Extensive forestry Intensive forestry Urban Annex VII shows
sector correspondence for the land use categories in the SCP-HAT Land use for crops and
pasture is allocated partly to the agriculture sector and partly to final demand The allocation to
final demand is made based on data on subsistence and low-input crop farming derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) For details on the
allocation methodology see Annex XXI Land use for intensive forestry is allocated to the wood
and paper industry (ie allocation to first intermediate users see Annex I) Land use for
extensive forestry is allocated partly to the wood and paper industry and partly to final demand
based on domestic wood fuel production and consumption statistics For details on the allocation
methodology see Annex XXI
Land use for other industrial activities than agriculture or forestry (eg mining) is not covered
From version v11 onwards built-up land is allocated directly to final demand and estimated
using OECD land use statistics (OECD 2018)
The definition of the two forestry land use classes used for the impact characterization is i)
Intensive Forest forests with extractive use with either even-aged stands and clear-cut
patches or less than three naturally occurring species at plantingseeding and ii) Extensive
Forests forests with extractive use and associated disturbance like hunting and selective
logging where timber extraction is followed by re-growth including at least three naturally
occurring tree species For the latter alternative uses to wood and paper eg recreation
hunting etc are not considered
Land use data for Annual crops Permanent crops and Pasture are gathered from FAOSTATrsquos
databases for the analogous categories arable land permanent crops and permanent meadows
and pastures (Food and Agriculture Organization of the United Nations 2018) Table 1 shows
data sources and model description for Extensive and Intensive Forestry
Following UNEPrsquos recommendations country-level average characterization factors for global
species loss from Chaudhary et al (2015) are used in the SCP-HAT aggregated over five taxa
(mammals reptiles birds amphibians and vascular plants) for each of the six land use
categories The unit of this indicator is PDFyear which stands for the Potentially Disappeared
Fraction of species for the duration of a year Land use impact modelling assumes that once an
activity (land use) stops the system will slowly return to the natural state The indicator
therefore does not reflect full extinction of species but a temporary decline in biodiversity

Air pollution and health impacts
Many emissions contribute to air pollution via a variety of mechanisms SCP-HAT focuses on air
pollution via particulate matter (PM) which is caused by emissions of PM itself as well as by
emissions of NH3 NOx and SO2 which form so-called secondary PM via chemical reactions The
UNEP LCI guidance for LCIA indicators (UNEP 2016) recommends the use of characterization
factors at end-point reflecting damages to human health expressed in Disability-Adjusted Life
Years (DALY) The recommended approach for calculating DALY impact factors is via emission
source archetypes but this could not be implemented at the global highly aggregated scale of
emissions data used in SCP-HAT The tool therefore uses DALY impact factors from RIVM
(Huijbregts et al 2016) which reflect country-averaged DALY impacts per unit of emission for
each of the four substances (PM25 NH3 SO2 NOx) No differentiation is made by emission source
type at this stage A recent set of new effect factors (Fantke et al 2019) is still only available
at country level without additional distinction of emission source type
The emissions data are taken from the EDGAR database (v432) This database covers all
countries and years up to and including 2012 For emissions of primary PM25 fossil and biogenic
sources are distinguished There is no difference in impact (DALYkg emitted) between those
two categories The data are extrapolated to 2013 and 2015 using GHG emissions trends with a
fixed emission ratio based on 2012 data As shown in Crippa et al (2018) emission ratios of air
pollutants to carbon dioxide have steadily decreased since 1970 but have been relatively stable
since around 2010 especially for NOx and SO2 More specifically PM25 fossil NOx and SO2 are
projected using CO2 emissions trends while CH4 and N2O (in CO2 eq) are used for PM25 bio and
NH3 During data processing it was found that this approach is not satisfactory for NH3 emissions
from agriculture and results are of especially high uncertainty for this category Thus future
improvements should prioritize this specific flow
Socio-economic data
The SCP-HAT includes a set of basic socioeconomic data which mainly serves for the estimation
of relative performance indicators of economies and industries eg carbon per unit of economic
output In the following the data sources used are listed
Population The World Bank Group
GDP The World Bank Group
Value added Eora database
Output Eora database
Employment per sector International Labour Organization
Country groups The World Bank Group
Government and private final consumption Eora database
HDI United Nations Development Programme
Country groups The World Bank Group
Employment by sector and gender is compiled from the ILO (International Labour Organization
2018) The dataset on employment by gender and sector includes only 14 sectors
Disaggregation is done using compensation to employees in Eora as proxy (ie it is assumed
same retribution between sectors belonging to an ILO category)
4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

private consumption from government consumption Finally often so-called ldquotruncation
errorsrdquo are produced as the indirect flows are not traced along the entire industrial supply
chains The most important advantage of coefficient-based approaches is the high level of
detail and transparency which can be applied in footprint-oriented indicator calculations
- As explained above input-output analysis allows tracing monetary flows and embodied
environmental factors from its origin (eg raw material extraction) to the final consumption
of the respective products The so-called ldquoLeontief inverserdquo a matrix generated from an
input-output table (see Annex I) shows for each commodity or industry represented in
the model all direct and indirect inputs and related environmental pressures and impacts
required along the complete supply chain Doing the calculation for all product groups all
environmental pressures and impacts needed to satisfy final demand of a country can be
quantified
A major advantage of input-output based approaches is that input-output tables
disaggregate a large number of different product groups and industries as well as final
demand categories (eg private consumption government consumption investments
etc) They allow calculating the footprints for all products and all sectors also those with
very complex supply chains and thus avoid truncation errors (see above) Finally the
countries of origin of a countryrsquos consumption footprint can be identified as well as the
countries of destination of the domestic environmental pressures and impacts
Consequently in contrast to coefficient-based approaches analyses of indirect trade flows
are done from the perspective of linking source countries with final demand in the
destination countries Hence trade analyses in Module 1 and 2 of SCP-HAT have to be
understood before this background import flows into a country of interest will only include
those pressures and impacts occurring abroad which contribute to the countryrsquos final
demand Export flows incorporate only the pressures and impacts which occur
domestically and contribute to final demand abroad Consequently flows which ldquopass
throughrdquo the country via imports and re-exports are not accounted for
When comparing results for a country of interest which stem from MRIO-based and
coefficient-based approaches conceptually the numbers for the consumption footprint can
be directly compared while those for trade flows cannot
EE-MRIO is complemented by impact assessment for the calculation of certain environmental
impact variables (using Life Cycle Impact Assessment (LCIA) characterization factors) While
environmental accounts used in EE-MRIO provide data on domestic resource use in the countries
around the world LCIA ldquotranslatesrdquo these amounts into environmental impacts such as
biodiversity loss from land use or resource depletion related to raw material use This
methodological step is realised in accordance with the LCIA guidelines set by the United Nations
Environment Programme (UNEP 2016)
Pressure and impact categories
Ideally the SCP-HAT tool would cover all indicators included in the 10-year framework of
programmes on sustainable consumption and production patterns (10YFP) Evaluation and
Monitoring Framework1 ie material use waste water use energy use GHG emissions air soil
and water pollutants biodiversity conservation and land use and human well-being indicators
related to gender decent work and health However for the development of the 2018 version
of the tool a first selection of highly relevant pressure and impact categories are implemented
Environmental pressures
o Raw material use
o Land use (occupation only)
o Emissions of greenhouse gases
o Emissions of particulate matter and precursors
Environmental impacts
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
The selection of a first set of pressures and impacts was guided by a set of criteria
Readiness of data availability
Relevance for SCP policy questions
Interrelatedness of pressures and impacts
Widely accepted impact characterization factors
Moreover the focus was set on an extensive coverage of related issues to be covered indirectly
with the selected domains For instance material flows include most energy carriers (and to a
large extend also cover energy) and allow for proxies for waste GHG emissions also have a large
overlap with energy use (more comprehensively when compared to material flows) They relate
1 httpwwwoneplanetnetworkorgresource10yfp-indicators-success
to two important policy areas of resource efficiency and climate mitigation identified as priorities
by many governments including the G7 and G20
Further categories to be integrated in future version of the SCP-HAT could include for example
Water use and water scarcity
Primary energy
Land transformation
Mercury emissions
Solid waste
Social life-cycle impacts (hazardous or child labour corruption etc)
Geographical and IndustryProduct coverage
The aim of SCP-HAT is to cover all countries in the world including those with relatively short
history of engaging more actively in policy making around policy areas such as SCP the SDGs
green economy etc The geographical coverage of SCP-HAT is based on the official list of UN
Member States2 but constrained by the country resolution of the databases utilised This choice
does not imply any political judgment All databases utilised in the SCP-HAT have their own
territorial definitions which do not always coincide especially regarding to former colonies
territories with independence partially recognized etc In total the SCP-HAT includes 171 UN
state members for which data are available in all databases There are some lsquospecial casesrsquo
Sudan includes South Sudan from 1990 to 2011 while Ethiopia includes Eritrea from 1990 to
1992 The full list is provided in Annex II The unified sector aggregation applied encompasses
26 economic sectorsproduct categories which is the level of detail of the underlying input-
output model (see below) A complete list can be found in the Annex III
3 Data sources
Multi-Regional Input-Output
There are a number of global input-output models available which allow for comprehensive EE-
MRIO modelling Depending on the political or scientific question to be answered they have their
strengths and weaknesses The input-output core applied in the SCP-HAT is the lsquoEorarsquo database
(Lenzen et al 2013 2012) Its major advantage in comparison to other available MRIO
databases is its geographical coverage of 188 single countries and thus the possibility to perform
nation-specific analysis for almost any country in the world Two Eora version are available the
2 httpwwwunorgenmember-states
Full Eora and the Eora26 The difference between them resides in the sectoral classification The
former uses the original sector disaggregation of the IO-tables as provided by the original source
Here the resolution varies between 26 and a few hundred sectors The latter applies a
harmonised 26sectors disaggregation for all countries For SCP-HAT we apply the Eora26 Even
though Full Eora can be considered more accurate using Eora26 avoids possible computational
problems since memory needs and server space would be significantly lower Time series are
available for 1990 to 2015 which is hence also the time span for the SCP-HAT
GHG emissions and Climate Change (Short-Term and Long-Term)
The UNEP LCI guidance for LCIA indicators makes an interim recommendation for considering
two impact categories for climate change short-term related to the rate of temperature change
and long-term related to the long-term temperature rise (UNEP 2016) The indicators
recommended for short-term and long-term respectively are Global Warming Potential 100
(GWP100) and Global Temperature change Potential (GTP100) at 100 years horizon The
corresponding characterization factors provided by UNEP are applied to GHG emissions data
with impact factors for 24 separate emissions including differentiation of fossil- and biogenic
methane (Full list of GWP and GTP factors in Annex IV) Near-term climate forcing gases are
excluded as the UNEP LCI guidance recommends those for sensitivity analysis only
Two sources are employed for compiling the SCP-HATrsquos GHG emissions input data The main
dataset was the PRIMAP-hist (PRIMAP ndash Potsdam Realtime Integrated Model for Probabilistic
Assessment of Emissions Paths) developed by the Potsdam Institute for Climate Impact Research
(Guumltschow et al 2019 2016) PRIMAP-hist was selected because of its coverage of long time
series and because it integrates other popular global GHG datasets (eg British Petroleum
Review of World Energy (BP 2014) Carbon Dioxide Information Analysis Center fossil fuel and
industrial CO2 emissions dataset (Boden et al 2015) the EDGAR dataset (Janssens-Maenhout
et al 2019) It includes emissions for the main Kyoto greenhouse gases carbon dioxide (CO2)
methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons
(PFCs)sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3) for the period of 1850 to 2016
The country detail is high including almost all countries considered in the SCP-HAT
The PRIMAP-hist sector categorization is based on the main Intergovernmental Panel on Climate
Change (IPCC) 2006 categories It has been analysed in the literature that too poor sector
resolution in the environmental extension of EE-MRIO models can cause aggregation errors
(Steen-Olsen et al 2014 Su et al 2010) and inclusion of external data for further
disaggregation is recommended (Lenzen 2011) To prevent this aggregation bias the PRIMAP-
hist data is further disaggregated using GHG emissions shares from the EDGAR database which
is maintained by the European Commission Joint Research Centre (JRC) and the Netherlands
Environmental Assessment Agency (PBL) (Janssens-Maenhout et al 2019 Olivier and Janssens-
Maenhout 2012) The shares of the different IPCC categories contributing to the total as reported
by EDGAR were applied to the totals published by PRIMAP-hist and used for SCP-HAT Three
specific EDGAR datasets are utilized the Edgar version 432 the EDGAR version 42 Fast Track
(FT) 2010 and the EDGAR version 42 For CO2 CH4 and N2O and the whole period Edgar
version 432 was used For SF6 the Edgar version 42 was used for the period 1990-1999 and
the Edgar version 42 FT for the period 2000-2010 Edgar shares from version 42 were adjusted
using the same approach as FAOSTAT for compiling their ldquoEmissions by sectorrdquo3 dataset For
HFCs and PFCs the EDGAR version 42 FT 2010 was used and shares from 2000 were assumed
as being equal for the period 1990-1999 For HFCs PFCs and SF6 shares for 2010 from Edgar
FT 2010 were applied for the disaggregation of the years 2011 to 2015 After the disaggregation
of the PRIMAP-hist data the IPCC 2006 categories were allocated to one or more sectors of the
SCP-HAT (ie Eora 26 sectors) The IPCC 2006 sector classification in the SCP-HAT and the
correspondence to the SCP-HAT sectors is provided in Annex V For those categories allocated
to more than one sector the emissions were disaggregated according to the relationship of the
total output of the sectors
Lastly emissions from road transportation from industries and households are recorded together
in PRIMAP-hits and EDGAR which need to be disaggregated for a finer analysis in the SCP-HAT
This was done applying the shares of different industries and households in the overall use of
the category lsquoPetroleum Chemical and Non-Metallic Mineral Productsrsquo as provided in Eora
Raw material use and mineral and fossil resource scarcity
For physical data for raw material extraction data from UN IRP Global Material Flows Database
(UN IRP 2017) are used It includes 13 aggregated raw material categories compiled following
lsquoeconomy-wide material flow accountingrsquo principles (Eurostat 2013 OECD 2008) for 192
countries including most of the countries of the SCP-HAT A full list of the raw material extraction
categories can be found in Annex VI National material extraction is allocated to the three
extractive sectors contained in the Eora26 sector classification ndash lsquoagriculturersquo lsquofishingrsquo and
lsquomining and quarryingrsquo While such a high aggregation of extractive sectors can result in a
distortion of the overall results (de Koning et al 2015 Pintildeero et al 2014) an improvement by
means for instance of allocating the extractions to intermediate users (Giljum et al 2017
Schaffartzik et al 2013 Wiebe et al 2012) ndash eg iron from mining to the steel industry ndash is
implemented in some cases The resulting allocation is sometimes referred as lsquouse extensionrsquo in
contrast to the most common lsquosupply extensionrsquo (further details in Annex I)
3 See httpwwwfaoorgfaostatendataEM
Raw material extraction for abiotic materials is translated into impacts by using the mineral and
fossil resource scarcity characterization factors from the Dutch National Institute for Public Health
and the Environment (RIVM) (Huijbregts et al 2016) The midpoint indicator (ie focussing on
intermediate stage along the impact pathway) for fossil resource scarcity is defined as the ratio
between the energy content of fossil resource x and the energy content of crude oil The unit of
this indicator is kg oil-equivalent and it simply reflects the energy content compared to a kilogram
of oil The characterization method for mineral resource scarcity is Surplus Ore Potential which
expresses the average extra amount of ore to be produced in the future due to the extraction of
1 kg of a mineral resource x In other words this reflects the decrease in ore grade of remaining
reserves The indicator is expressed relative to copper in units of kg Cu-equivalent The
ldquohierarchistrdquo version of this indicator is applied which means that future production is chosen to
be the ultimate recoverable resource For more details see RIVM (Huijbregts et al 2016) An
unweighted average characterization factor for the group of ldquoOther metalsrdquo was derived using
the 25 materials listed in that category in the Global Material Flows Database The resulting
factor was dominated by caesium which is probably higher than realistic In version 11 the
characterization factor for the group of ldquoOther metalsrdquo was updated by using a global-production-
weighted average (averaged over the years 2012-2014 as data for some metals are only
available after 2012) This resulted in a significant reduction of the factor with the main
contributors being mercury magnesium zirconium and hafnium
Land use and potential species loss from land use
The UNEP LCI guidance for LCIA indicators makes an interim recommendation (see UNEP 2016)
for characterization of biodiversity impacts of land use discerning occupation and
transformation based on the method developed by Chaudhary et al (2015) In this first version
of the SCP-HAT only land occupation is included and modelling of land transformation is left for
future tool developments To allow for the application of the recommended characterization
factors inventory data is required for land occupation (m2a) for six land use classes - Annual
crops Permanent crops Pasture Extensive forestry Intensive forestry Urban Annex VII shows
sector correspondence for the land use categories in the SCP-HAT Land use for crops and
pasture is allocated partly to the agriculture sector and partly to final demand The allocation to
final demand is made based on data on subsistence and low-input crop farming derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) For details on the
allocation methodology see Annex XXI Land use for intensive forestry is allocated to the wood
and paper industry (ie allocation to first intermediate users see Annex I) Land use for
extensive forestry is allocated partly to the wood and paper industry and partly to final demand
based on domestic wood fuel production and consumption statistics For details on the allocation
methodology see Annex XXI
Land use for other industrial activities than agriculture or forestry (eg mining) is not covered
From version v11 onwards built-up land is allocated directly to final demand and estimated
using OECD land use statistics (OECD 2018)
The definition of the two forestry land use classes used for the impact characterization is i)
Intensive Forest forests with extractive use with either even-aged stands and clear-cut
patches or less than three naturally occurring species at plantingseeding and ii) Extensive
Forests forests with extractive use and associated disturbance like hunting and selective
logging where timber extraction is followed by re-growth including at least three naturally
occurring tree species For the latter alternative uses to wood and paper eg recreation
hunting etc are not considered
Land use data for Annual crops Permanent crops and Pasture are gathered from FAOSTATrsquos
databases for the analogous categories arable land permanent crops and permanent meadows
and pastures (Food and Agriculture Organization of the United Nations 2018) Table 1 shows
data sources and model description for Extensive and Intensive Forestry
Following UNEPrsquos recommendations country-level average characterization factors for global
species loss from Chaudhary et al (2015) are used in the SCP-HAT aggregated over five taxa
(mammals reptiles birds amphibians and vascular plants) for each of the six land use
categories The unit of this indicator is PDFyear which stands for the Potentially Disappeared
Fraction of species for the duration of a year Land use impact modelling assumes that once an
activity (land use) stops the system will slowly return to the natural state The indicator
therefore does not reflect full extinction of species but a temporary decline in biodiversity

Air pollution and health impacts
Many emissions contribute to air pollution via a variety of mechanisms SCP-HAT focuses on air
pollution via particulate matter (PM) which is caused by emissions of PM itself as well as by
emissions of NH3 NOx and SO2 which form so-called secondary PM via chemical reactions The
UNEP LCI guidance for LCIA indicators (UNEP 2016) recommends the use of characterization
factors at end-point reflecting damages to human health expressed in Disability-Adjusted Life
Years (DALY) The recommended approach for calculating DALY impact factors is via emission
source archetypes but this could not be implemented at the global highly aggregated scale of
emissions data used in SCP-HAT The tool therefore uses DALY impact factors from RIVM
(Huijbregts et al 2016) which reflect country-averaged DALY impacts per unit of emission for
each of the four substances (PM25 NH3 SO2 NOx) No differentiation is made by emission source
type at this stage A recent set of new effect factors (Fantke et al 2019) is still only available
at country level without additional distinction of emission source type
The emissions data are taken from the EDGAR database (v432) This database covers all
countries and years up to and including 2012 For emissions of primary PM25 fossil and biogenic
sources are distinguished There is no difference in impact (DALYkg emitted) between those
two categories The data are extrapolated to 2013 and 2015 using GHG emissions trends with a
fixed emission ratio based on 2012 data As shown in Crippa et al (2018) emission ratios of air
pollutants to carbon dioxide have steadily decreased since 1970 but have been relatively stable
since around 2010 especially for NOx and SO2 More specifically PM25 fossil NOx and SO2 are
projected using CO2 emissions trends while CH4 and N2O (in CO2 eq) are used for PM25 bio and
NH3 During data processing it was found that this approach is not satisfactory for NH3 emissions
from agriculture and results are of especially high uncertainty for this category Thus future
improvements should prioritize this specific flow
Socio-economic data
The SCP-HAT includes a set of basic socioeconomic data which mainly serves for the estimation
of relative performance indicators of economies and industries eg carbon per unit of economic
output In the following the data sources used are listed
Population The World Bank Group
GDP The World Bank Group
Value added Eora database
Output Eora database
Employment per sector International Labour Organization
Country groups The World Bank Group
Government and private final consumption Eora database
HDI United Nations Development Programme
Country groups The World Bank Group
Employment by sector and gender is compiled from the ILO (International Labour Organization
2018) The dataset on employment by gender and sector includes only 14 sectors
Disaggregation is done using compensation to employees in Eora as proxy (ie it is assumed
same retribution between sectors belonging to an ILO category)
4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the

Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Pressure and impact categories
Ideally the SCP-HAT tool would cover all indicators included in the 10-year framework of
programmes on sustainable consumption and production patterns (10YFP) Evaluation and
Monitoring Framework1 ie material use waste water use energy use GHG emissions air soil
and water pollutants biodiversity conservation and land use and human well-being indicators
related to gender decent work and health However for the development of the 2018 version
of the tool a first selection of highly relevant pressure and impact categories are implemented
Environmental pressures
o Raw material use
o Land use (occupation only)
o Emissions of greenhouse gases
o Emissions of particulate matter and precursors
Environmental impacts
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
The selection of a first set of pressures and impacts was guided by a set of criteria
Readiness of data availability
Relevance for SCP policy questions
Interrelatedness of pressures and impacts
Widely accepted impact characterization factors
Moreover the focus was set on an extensive coverage of related issues to be covered indirectly
with the selected domains For instance material flows include most energy carriers (and to a
large extend also cover energy) and allow for proxies for waste GHG emissions also have a large
overlap with energy use (more comprehensively when compared to material flows) They relate
1 httpwwwoneplanetnetworkorgresource10yfp-indicators-success
to two important policy areas of resource efficiency and climate mitigation identified as priorities
by many governments including the G7 and G20
Further categories to be integrated in future version of the SCP-HAT could include for example
Water use and water scarcity
Primary energy
Land transformation
Mercury emissions
Solid waste
Social life-cycle impacts (hazardous or child labour corruption etc)
Geographical and IndustryProduct coverage
The aim of SCP-HAT is to cover all countries in the world including those with relatively short
history of engaging more actively in policy making around policy areas such as SCP the SDGs
green economy etc The geographical coverage of SCP-HAT is based on the official list of UN
Member States2 but constrained by the country resolution of the databases utilised This choice
does not imply any political judgment All databases utilised in the SCP-HAT have their own
territorial definitions which do not always coincide especially regarding to former colonies
territories with independence partially recognized etc In total the SCP-HAT includes 171 UN
state members for which data are available in all databases There are some lsquospecial casesrsquo
Sudan includes South Sudan from 1990 to 2011 while Ethiopia includes Eritrea from 1990 to
1992 The full list is provided in Annex II The unified sector aggregation applied encompasses
26 economic sectorsproduct categories which is the level of detail of the underlying input-
output model (see below) A complete list can be found in the Annex III
3 Data sources
Multi-Regional Input-Output
There are a number of global input-output models available which allow for comprehensive EE-
MRIO modelling Depending on the political or scientific question to be answered they have their
strengths and weaknesses The input-output core applied in the SCP-HAT is the lsquoEorarsquo database
(Lenzen et al 2013 2012) Its major advantage in comparison to other available MRIO
databases is its geographical coverage of 188 single countries and thus the possibility to perform
nation-specific analysis for almost any country in the world Two Eora version are available the
2 httpwwwunorgenmember-states
Full Eora and the Eora26 The difference between them resides in the sectoral classification The
former uses the original sector disaggregation of the IO-tables as provided by the original source
Here the resolution varies between 26 and a few hundred sectors The latter applies a
harmonised 26sectors disaggregation for all countries For SCP-HAT we apply the Eora26 Even
though Full Eora can be considered more accurate using Eora26 avoids possible computational
problems since memory needs and server space would be significantly lower Time series are
available for 1990 to 2015 which is hence also the time span for the SCP-HAT
GHG emissions and Climate Change (Short-Term and Long-Term)
The UNEP LCI guidance for LCIA indicators makes an interim recommendation for considering
two impact categories for climate change short-term related to the rate of temperature change
and long-term related to the long-term temperature rise (UNEP 2016) The indicators
recommended for short-term and long-term respectively are Global Warming Potential 100
(GWP100) and Global Temperature change Potential (GTP100) at 100 years horizon The
corresponding characterization factors provided by UNEP are applied to GHG emissions data
with impact factors for 24 separate emissions including differentiation of fossil- and biogenic
methane (Full list of GWP and GTP factors in Annex IV) Near-term climate forcing gases are
excluded as the UNEP LCI guidance recommends those for sensitivity analysis only
Two sources are employed for compiling the SCP-HATrsquos GHG emissions input data The main
dataset was the PRIMAP-hist (PRIMAP ndash Potsdam Realtime Integrated Model for Probabilistic
Assessment of Emissions Paths) developed by the Potsdam Institute for Climate Impact Research
(Guumltschow et al 2019 2016) PRIMAP-hist was selected because of its coverage of long time
series and because it integrates other popular global GHG datasets (eg British Petroleum
Review of World Energy (BP 2014) Carbon Dioxide Information Analysis Center fossil fuel and
industrial CO2 emissions dataset (Boden et al 2015) the EDGAR dataset (Janssens-Maenhout
et al 2019) It includes emissions for the main Kyoto greenhouse gases carbon dioxide (CO2)
methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons
(PFCs)sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3) for the period of 1850 to 2016
The country detail is high including almost all countries considered in the SCP-HAT
The PRIMAP-hist sector categorization is based on the main Intergovernmental Panel on Climate
Change (IPCC) 2006 categories It has been analysed in the literature that too poor sector
resolution in the environmental extension of EE-MRIO models can cause aggregation errors
(Steen-Olsen et al 2014 Su et al 2010) and inclusion of external data for further
disaggregation is recommended (Lenzen 2011) To prevent this aggregation bias the PRIMAP-
hist data is further disaggregated using GHG emissions shares from the EDGAR database which
is maintained by the European Commission Joint Research Centre (JRC) and the Netherlands
Environmental Assessment Agency (PBL) (Janssens-Maenhout et al 2019 Olivier and Janssens-
Maenhout 2012) The shares of the different IPCC categories contributing to the total as reported
by EDGAR were applied to the totals published by PRIMAP-hist and used for SCP-HAT Three
specific EDGAR datasets are utilized the Edgar version 432 the EDGAR version 42 Fast Track
(FT) 2010 and the EDGAR version 42 For CO2 CH4 and N2O and the whole period Edgar
version 432 was used For SF6 the Edgar version 42 was used for the period 1990-1999 and
the Edgar version 42 FT for the period 2000-2010 Edgar shares from version 42 were adjusted
using the same approach as FAOSTAT for compiling their ldquoEmissions by sectorrdquo3 dataset For
HFCs and PFCs the EDGAR version 42 FT 2010 was used and shares from 2000 were assumed
as being equal for the period 1990-1999 For HFCs PFCs and SF6 shares for 2010 from Edgar
FT 2010 were applied for the disaggregation of the years 2011 to 2015 After the disaggregation
of the PRIMAP-hist data the IPCC 2006 categories were allocated to one or more sectors of the
SCP-HAT (ie Eora 26 sectors) The IPCC 2006 sector classification in the SCP-HAT and the
correspondence to the SCP-HAT sectors is provided in Annex V For those categories allocated
to more than one sector the emissions were disaggregated according to the relationship of the
total output of the sectors
Lastly emissions from road transportation from industries and households are recorded together
in PRIMAP-hits and EDGAR which need to be disaggregated for a finer analysis in the SCP-HAT
This was done applying the shares of different industries and households in the overall use of
the category lsquoPetroleum Chemical and Non-Metallic Mineral Productsrsquo as provided in Eora
Raw material use and mineral and fossil resource scarcity
For physical data for raw material extraction data from UN IRP Global Material Flows Database
(UN IRP 2017) are used It includes 13 aggregated raw material categories compiled following
lsquoeconomy-wide material flow accountingrsquo principles (Eurostat 2013 OECD 2008) for 192
countries including most of the countries of the SCP-HAT A full list of the raw material extraction
categories can be found in Annex VI National material extraction is allocated to the three
extractive sectors contained in the Eora26 sector classification ndash lsquoagriculturersquo lsquofishingrsquo and
lsquomining and quarryingrsquo While such a high aggregation of extractive sectors can result in a
distortion of the overall results (de Koning et al 2015 Pintildeero et al 2014) an improvement by
means for instance of allocating the extractions to intermediate users (Giljum et al 2017
Schaffartzik et al 2013 Wiebe et al 2012) ndash eg iron from mining to the steel industry ndash is
implemented in some cases The resulting allocation is sometimes referred as lsquouse extensionrsquo in
contrast to the most common lsquosupply extensionrsquo (further details in Annex I)
3 See httpwwwfaoorgfaostatendataEM
Raw material extraction for abiotic materials is translated into impacts by using the mineral and
fossil resource scarcity characterization factors from the Dutch National Institute for Public Health
and the Environment (RIVM) (Huijbregts et al 2016) The midpoint indicator (ie focussing on
intermediate stage along the impact pathway) for fossil resource scarcity is defined as the ratio
between the energy content of fossil resource x and the energy content of crude oil The unit of
this indicator is kg oil-equivalent and it simply reflects the energy content compared to a kilogram
of oil The characterization method for mineral resource scarcity is Surplus Ore Potential which
expresses the average extra amount of ore to be produced in the future due to the extraction of
1 kg of a mineral resource x In other words this reflects the decrease in ore grade of remaining
reserves The indicator is expressed relative to copper in units of kg Cu-equivalent The
ldquohierarchistrdquo version of this indicator is applied which means that future production is chosen to
be the ultimate recoverable resource For more details see RIVM (Huijbregts et al 2016) An
unweighted average characterization factor for the group of ldquoOther metalsrdquo was derived using
the 25 materials listed in that category in the Global Material Flows Database The resulting
factor was dominated by caesium which is probably higher than realistic In version 11 the
characterization factor for the group of ldquoOther metalsrdquo was updated by using a global-production-
weighted average (averaged over the years 2012-2014 as data for some metals are only
available after 2012) This resulted in a significant reduction of the factor with the main
contributors being mercury magnesium zirconium and hafnium
Land use and potential species loss from land use
The UNEP LCI guidance for LCIA indicators makes an interim recommendation (see UNEP 2016)
for characterization of biodiversity impacts of land use discerning occupation and
transformation based on the method developed by Chaudhary et al (2015) In this first version
of the SCP-HAT only land occupation is included and modelling of land transformation is left for
future tool developments To allow for the application of the recommended characterization
factors inventory data is required for land occupation (m2a) for six land use classes - Annual
crops Permanent crops Pasture Extensive forestry Intensive forestry Urban Annex VII shows
sector correspondence for the land use categories in the SCP-HAT Land use for crops and
pasture is allocated partly to the agriculture sector and partly to final demand The allocation to
final demand is made based on data on subsistence and low-input crop farming derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) For details on the
allocation methodology see Annex XXI Land use for intensive forestry is allocated to the wood
and paper industry (ie allocation to first intermediate users see Annex I) Land use for
extensive forestry is allocated partly to the wood and paper industry and partly to final demand
based on domestic wood fuel production and consumption statistics For details on the allocation
methodology see Annex XXI
Land use for other industrial activities than agriculture or forestry (eg mining) is not covered
From version v11 onwards built-up land is allocated directly to final demand and estimated
using OECD land use statistics (OECD 2018)
The definition of the two forestry land use classes used for the impact characterization is i)
Intensive Forest forests with extractive use with either even-aged stands and clear-cut
patches or less than three naturally occurring species at plantingseeding and ii) Extensive
Forests forests with extractive use and associated disturbance like hunting and selective
logging where timber extraction is followed by re-growth including at least three naturally
occurring tree species For the latter alternative uses to wood and paper eg recreation
hunting etc are not considered
Land use data for Annual crops Permanent crops and Pasture are gathered from FAOSTATrsquos
databases for the analogous categories arable land permanent crops and permanent meadows
and pastures (Food and Agriculture Organization of the United Nations 2018) Table 1 shows
data sources and model description for Extensive and Intensive Forestry
Following UNEPrsquos recommendations country-level average characterization factors for global
species loss from Chaudhary et al (2015) are used in the SCP-HAT aggregated over five taxa
(mammals reptiles birds amphibians and vascular plants) for each of the six land use
categories The unit of this indicator is PDFyear which stands for the Potentially Disappeared
Fraction of species for the duration of a year Land use impact modelling assumes that once an
activity (land use) stops the system will slowly return to the natural state The indicator
therefore does not reflect full extinction of species but a temporary decline in biodiversity

Air pollution and health impacts
Many emissions contribute to air pollution via a variety of mechanisms SCP-HAT focuses on air
pollution via particulate matter (PM) which is caused by emissions of PM itself as well as by
emissions of NH3 NOx and SO2 which form so-called secondary PM via chemical reactions The
UNEP LCI guidance for LCIA indicators (UNEP 2016) recommends the use of characterization
factors at end-point reflecting damages to human health expressed in Disability-Adjusted Life
Years (DALY) The recommended approach for calculating DALY impact factors is via emission
source archetypes but this could not be implemented at the global highly aggregated scale of
emissions data used in SCP-HAT The tool therefore uses DALY impact factors from RIVM
(Huijbregts et al 2016) which reflect country-averaged DALY impacts per unit of emission for
each of the four substances (PM25 NH3 SO2 NOx) No differentiation is made by emission source
type at this stage A recent set of new effect factors (Fantke et al 2019) is still only available
at country level without additional distinction of emission source type
The emissions data are taken from the EDGAR database (v432) This database covers all
countries and years up to and including 2012 For emissions of primary PM25 fossil and biogenic
sources are distinguished There is no difference in impact (DALYkg emitted) between those
two categories The data are extrapolated to 2013 and 2015 using GHG emissions trends with a
fixed emission ratio based on 2012 data As shown in Crippa et al (2018) emission ratios of air
pollutants to carbon dioxide have steadily decreased since 1970 but have been relatively stable
since around 2010 especially for NOx and SO2 More specifically PM25 fossil NOx and SO2 are
projected using CO2 emissions trends while CH4 and N2O (in CO2 eq) are used for PM25 bio and
NH3 During data processing it was found that this approach is not satisfactory for NH3 emissions
from agriculture and results are of especially high uncertainty for this category Thus future
improvements should prioritize this specific flow
Socio-economic data
The SCP-HAT includes a set of basic socioeconomic data which mainly serves for the estimation
of relative performance indicators of economies and industries eg carbon per unit of economic
output In the following the data sources used are listed
Population The World Bank Group
GDP The World Bank Group
Value added Eora database
Output Eora database
Employment per sector International Labour Organization
Country groups The World Bank Group
Government and private final consumption Eora database
HDI United Nations Development Programme
Country groups The World Bank Group
Employment by sector and gender is compiled from the ILO (International Labour Organization
2018) The dataset on employment by gender and sector includes only 14 sectors
Disaggregation is done using compensation to employees in Eora as proxy (ie it is assumed
same retribution between sectors belonging to an ILO category)
4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10
Land use and potential species loss from land use
Allocation allocation to households implemented for land use for annual crops permanent
crops pasture and extensive forestry
Bug fixes intensive and extensive forestry labels flipped in v10 for ldquoconsumption
footprintrdquo approach and environmental trends graphs
Country classification
Approach Homogenization of the approach for states that entered in existence or
disappeared within the time period considered in SCP-HAT this refers to ex-soviets
countries former Yugoslavia former Czechoslovakia Ethiopia-Eritrea and Sudan and
South Sudan Only currently existing countries are displayed
User interface
Bug fixes Graphs didnrsquot re-scale when a environmental sub-category is isolated (eg CH4
emissions) was selected in v10 (in ldquoEnvironmental Trendsrdquo and ldquoTrends by sectorrdquo) in
Module 2 Hotspots Identification Further simultaneous data filtering and plotting were not
supported in v10 Module 3 National Data System
Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Geographical and IndustryProduct coverage
The aim of SCP-HAT is to cover all countries in the world including those with relatively short
history of engaging more actively in policy making around policy areas such as SCP the SDGs
green economy etc The geographical coverage of SCP-HAT is based on the official list of UN
Member States2 but constrained by the country resolution of the databases utilised This choice
does not imply any political judgment All databases utilised in the SCP-HAT have their own
territorial definitions which do not always coincide especially regarding to former colonies
territories with independence partially recognized etc In total the SCP-HAT includes 171 UN
state members for which data are available in all databases There are some lsquospecial casesrsquo
Sudan includes South Sudan from 1990 to 2011 while Ethiopia includes Eritrea from 1990 to
1992 The full list is provided in Annex II The unified sector aggregation applied encompasses
26 economic sectorsproduct categories which is the level of detail of the underlying input-
output model (see below) A complete list can be found in the Annex III
3 Data sources
Multi-Regional Input-Output
There are a number of global input-output models available which allow for comprehensive EE-
MRIO modelling Depending on the political or scientific question to be answered they have their
strengths and weaknesses The input-output core applied in the SCP-HAT is the lsquoEorarsquo database
(Lenzen et al 2013 2012) Its major advantage in comparison to other available MRIO
databases is its geographical coverage of 188 single countries and thus the possibility to perform
nation-specific analysis for almost any country in the world Two Eora version are available the
2 httpwwwunorgenmember-states
Full Eora and the Eora26 The difference between them resides in the sectoral classification The
former uses the original sector disaggregation of the IO-tables as provided by the original source
Here the resolution varies between 26 and a few hundred sectors The latter applies a
harmonised 26sectors disaggregation for all countries For SCP-HAT we apply the Eora26 Even
though Full Eora can be considered more accurate using Eora26 avoids possible computational
problems since memory needs and server space would be significantly lower Time series are
available for 1990 to 2015 which is hence also the time span for the SCP-HAT
GHG emissions and Climate Change (Short-Term and Long-Term)
The UNEP LCI guidance for LCIA indicators makes an interim recommendation for considering
two impact categories for climate change short-term related to the rate of temperature change
and long-term related to the long-term temperature rise (UNEP 2016) The indicators
recommended for short-term and long-term respectively are Global Warming Potential 100
(GWP100) and Global Temperature change Potential (GTP100) at 100 years horizon The
corresponding characterization factors provided by UNEP are applied to GHG emissions data
with impact factors for 24 separate emissions including differentiation of fossil- and biogenic
methane (Full list of GWP and GTP factors in Annex IV) Near-term climate forcing gases are
excluded as the UNEP LCI guidance recommends those for sensitivity analysis only
Two sources are employed for compiling the SCP-HATrsquos GHG emissions input data The main
dataset was the PRIMAP-hist (PRIMAP ndash Potsdam Realtime Integrated Model for Probabilistic
Assessment of Emissions Paths) developed by the Potsdam Institute for Climate Impact Research
(Guumltschow et al 2019 2016) PRIMAP-hist was selected because of its coverage of long time
series and because it integrates other popular global GHG datasets (eg British Petroleum
Review of World Energy (BP 2014) Carbon Dioxide Information Analysis Center fossil fuel and
industrial CO2 emissions dataset (Boden et al 2015) the EDGAR dataset (Janssens-Maenhout
et al 2019) It includes emissions for the main Kyoto greenhouse gases carbon dioxide (CO2)
methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons
(PFCs)sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3) for the period of 1850 to 2016
The country detail is high including almost all countries considered in the SCP-HAT
The PRIMAP-hist sector categorization is based on the main Intergovernmental Panel on Climate
Change (IPCC) 2006 categories It has been analysed in the literature that too poor sector
resolution in the environmental extension of EE-MRIO models can cause aggregation errors
(Steen-Olsen et al 2014 Su et al 2010) and inclusion of external data for further
disaggregation is recommended (Lenzen 2011) To prevent this aggregation bias the PRIMAP-
hist data is further disaggregated using GHG emissions shares from the EDGAR database which
is maintained by the European Commission Joint Research Centre (JRC) and the Netherlands
Environmental Assessment Agency (PBL) (Janssens-Maenhout et al 2019 Olivier and Janssens-
Maenhout 2012) The shares of the different IPCC categories contributing to the total as reported
by EDGAR were applied to the totals published by PRIMAP-hist and used for SCP-HAT Three
specific EDGAR datasets are utilized the Edgar version 432 the EDGAR version 42 Fast Track
(FT) 2010 and the EDGAR version 42 For CO2 CH4 and N2O and the whole period Edgar
version 432 was used For SF6 the Edgar version 42 was used for the period 1990-1999 and
the Edgar version 42 FT for the period 2000-2010 Edgar shares from version 42 were adjusted
using the same approach as FAOSTAT for compiling their ldquoEmissions by sectorrdquo3 dataset For
HFCs and PFCs the EDGAR version 42 FT 2010 was used and shares from 2000 were assumed
as being equal for the period 1990-1999 For HFCs PFCs and SF6 shares for 2010 from Edgar
FT 2010 were applied for the disaggregation of the years 2011 to 2015 After the disaggregation
of the PRIMAP-hist data the IPCC 2006 categories were allocated to one or more sectors of the
SCP-HAT (ie Eora 26 sectors) The IPCC 2006 sector classification in the SCP-HAT and the
correspondence to the SCP-HAT sectors is provided in Annex V For those categories allocated
to more than one sector the emissions were disaggregated according to the relationship of the
total output of the sectors
Lastly emissions from road transportation from industries and households are recorded together
in PRIMAP-hits and EDGAR which need to be disaggregated for a finer analysis in the SCP-HAT
This was done applying the shares of different industries and households in the overall use of
the category lsquoPetroleum Chemical and Non-Metallic Mineral Productsrsquo as provided in Eora
Raw material use and mineral and fossil resource scarcity
For physical data for raw material extraction data from UN IRP Global Material Flows Database
(UN IRP 2017) are used It includes 13 aggregated raw material categories compiled following
lsquoeconomy-wide material flow accountingrsquo principles (Eurostat 2013 OECD 2008) for 192
countries including most of the countries of the SCP-HAT A full list of the raw material extraction
categories can be found in Annex VI National material extraction is allocated to the three
extractive sectors contained in the Eora26 sector classification ndash lsquoagriculturersquo lsquofishingrsquo and
lsquomining and quarryingrsquo While such a high aggregation of extractive sectors can result in a
distortion of the overall results (de Koning et al 2015 Pintildeero et al 2014) an improvement by
means for instance of allocating the extractions to intermediate users (Giljum et al 2017
Schaffartzik et al 2013 Wiebe et al 2012) ndash eg iron from mining to the steel industry ndash is
implemented in some cases The resulting allocation is sometimes referred as lsquouse extensionrsquo in
contrast to the most common lsquosupply extensionrsquo (further details in Annex I)
3 See httpwwwfaoorgfaostatendataEM
Raw material extraction for abiotic materials is translated into impacts by using the mineral and
fossil resource scarcity characterization factors from the Dutch National Institute for Public Health
and the Environment (RIVM) (Huijbregts et al 2016) The midpoint indicator (ie focussing on
intermediate stage along the impact pathway) for fossil resource scarcity is defined as the ratio
between the energy content of fossil resource x and the energy content of crude oil The unit of
this indicator is kg oil-equivalent and it simply reflects the energy content compared to a kilogram
of oil The characterization method for mineral resource scarcity is Surplus Ore Potential which
expresses the average extra amount of ore to be produced in the future due to the extraction of
1 kg of a mineral resource x In other words this reflects the decrease in ore grade of remaining
reserves The indicator is expressed relative to copper in units of kg Cu-equivalent The
ldquohierarchistrdquo version of this indicator is applied which means that future production is chosen to
be the ultimate recoverable resource For more details see RIVM (Huijbregts et al 2016) An
unweighted average characterization factor for the group of ldquoOther metalsrdquo was derived using
the 25 materials listed in that category in the Global Material Flows Database The resulting
factor was dominated by caesium which is probably higher than realistic In version 11 the
characterization factor for the group of ldquoOther metalsrdquo was updated by using a global-production-
weighted average (averaged over the years 2012-2014 as data for some metals are only
available after 2012) This resulted in a significant reduction of the factor with the main
contributors being mercury magnesium zirconium and hafnium
Land use and potential species loss from land use
The UNEP LCI guidance for LCIA indicators makes an interim recommendation (see UNEP 2016)
for characterization of biodiversity impacts of land use discerning occupation and
transformation based on the method developed by Chaudhary et al (2015) In this first version
of the SCP-HAT only land occupation is included and modelling of land transformation is left for
future tool developments To allow for the application of the recommended characterization
factors inventory data is required for land occupation (m2a) for six land use classes - Annual
crops Permanent crops Pasture Extensive forestry Intensive forestry Urban Annex VII shows
sector correspondence for the land use categories in the SCP-HAT Land use for crops and
pasture is allocated partly to the agriculture sector and partly to final demand The allocation to
final demand is made based on data on subsistence and low-input crop farming derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) For details on the
allocation methodology see Annex XXI Land use for intensive forestry is allocated to the wood
and paper industry (ie allocation to first intermediate users see Annex I) Land use for
extensive forestry is allocated partly to the wood and paper industry and partly to final demand
based on domestic wood fuel production and consumption statistics For details on the allocation
methodology see Annex XXI
Land use for other industrial activities than agriculture or forestry (eg mining) is not covered
From version v11 onwards built-up land is allocated directly to final demand and estimated
using OECD land use statistics (OECD 2018)
The definition of the two forestry land use classes used for the impact characterization is i)
Intensive Forest forests with extractive use with either even-aged stands and clear-cut
patches or less than three naturally occurring species at plantingseeding and ii) Extensive
Forests forests with extractive use and associated disturbance like hunting and selective
logging where timber extraction is followed by re-growth including at least three naturally
occurring tree species For the latter alternative uses to wood and paper eg recreation
hunting etc are not considered
Land use data for Annual crops Permanent crops and Pasture are gathered from FAOSTATrsquos
databases for the analogous categories arable land permanent crops and permanent meadows
and pastures (Food and Agriculture Organization of the United Nations 2018) Table 1 shows
data sources and model description for Extensive and Intensive Forestry
Following UNEPrsquos recommendations country-level average characterization factors for global
species loss from Chaudhary et al (2015) are used in the SCP-HAT aggregated over five taxa
(mammals reptiles birds amphibians and vascular plants) for each of the six land use
categories The unit of this indicator is PDFyear which stands for the Potentially Disappeared
Fraction of species for the duration of a year Land use impact modelling assumes that once an
activity (land use) stops the system will slowly return to the natural state The indicator
therefore does not reflect full extinction of species but a temporary decline in biodiversity

Air pollution and health impacts
Many emissions contribute to air pollution via a variety of mechanisms SCP-HAT focuses on air
pollution via particulate matter (PM) which is caused by emissions of PM itself as well as by
emissions of NH3 NOx and SO2 which form so-called secondary PM via chemical reactions The
UNEP LCI guidance for LCIA indicators (UNEP 2016) recommends the use of characterization
factors at end-point reflecting damages to human health expressed in Disability-Adjusted Life
Years (DALY) The recommended approach for calculating DALY impact factors is via emission
source archetypes but this could not be implemented at the global highly aggregated scale of
emissions data used in SCP-HAT The tool therefore uses DALY impact factors from RIVM
(Huijbregts et al 2016) which reflect country-averaged DALY impacts per unit of emission for
each of the four substances (PM25 NH3 SO2 NOx) No differentiation is made by emission source
type at this stage A recent set of new effect factors (Fantke et al 2019) is still only available
at country level without additional distinction of emission source type
The emissions data are taken from the EDGAR database (v432) This database covers all
countries and years up to and including 2012 For emissions of primary PM25 fossil and biogenic
sources are distinguished There is no difference in impact (DALYkg emitted) between those
two categories The data are extrapolated to 2013 and 2015 using GHG emissions trends with a
fixed emission ratio based on 2012 data As shown in Crippa et al (2018) emission ratios of air
pollutants to carbon dioxide have steadily decreased since 1970 but have been relatively stable
since around 2010 especially for NOx and SO2 More specifically PM25 fossil NOx and SO2 are
projected using CO2 emissions trends while CH4 and N2O (in CO2 eq) are used for PM25 bio and
NH3 During data processing it was found that this approach is not satisfactory for NH3 emissions
from agriculture and results are of especially high uncertainty for this category Thus future
improvements should prioritize this specific flow
Socio-economic data
The SCP-HAT includes a set of basic socioeconomic data which mainly serves for the estimation
of relative performance indicators of economies and industries eg carbon per unit of economic
output In the following the data sources used are listed
Population The World Bank Group
GDP The World Bank Group
Value added Eora database
Output Eora database
Employment per sector International Labour Organization
Country groups The World Bank Group
Government and private final consumption Eora database
HDI United Nations Development Programme
Country groups The World Bank Group
Employment by sector and gender is compiled from the ILO (International Labour Organization
2018) The dataset on employment by gender and sector includes only 14 sectors
Disaggregation is done using compensation to employees in Eora as proxy (ie it is assumed
same retribution between sectors belonging to an ILO category)
4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10
Land use and potential species loss from land use
Allocation allocation to households implemented for land use for annual crops permanent
crops pasture and extensive forestry
Bug fixes intensive and extensive forestry labels flipped in v10 for ldquoconsumption
footprintrdquo approach and environmental trends graphs
Country classification
Approach Homogenization of the approach for states that entered in existence or
disappeared within the time period considered in SCP-HAT this refers to ex-soviets
countries former Yugoslavia former Czechoslovakia Ethiopia-Eritrea and Sudan and
South Sudan Only currently existing countries are displayed

supported in v10 Module 3 National Data System
Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case
4 ABARES 2018 National Land Use Summary Statistics 2000-2001 version 2018-04-12
httpsdatagovaudatadatasetland-use-of-australia-version-3-28093-20012002
of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Full Eora and the Eora26 The difference between them resides in the sectoral classification The
former uses the original sector disaggregation of the IO-tables as provided by the original source
Here the resolution varies between 26 and a few hundred sectors The latter applies a
harmonised 26sectors disaggregation for all countries For SCP-HAT we apply the Eora26 Even
though Full Eora can be considered more accurate using Eora26 avoids possible computational
problems since memory needs and server space would be significantly lower Time series are
available for 1990 to 2015 which is hence also the time span for the SCP-HAT
GHG emissions and Climate Change (Short-Term and Long-Term)
The UNEP LCI guidance for LCIA indicators makes an interim recommendation for considering
two impact categories for climate change short-term related to the rate of temperature change
and long-term related to the long-term temperature rise (UNEP 2016) The indicators
recommended for short-term and long-term respectively are Global Warming Potential 100
(GWP100) and Global Temperature change Potential (GTP100) at 100 years horizon The
corresponding characterization factors provided by UNEP are applied to GHG emissions data
with impact factors for 24 separate emissions including differentiation of fossil- and biogenic
methane (Full list of GWP and GTP factors in Annex IV) Near-term climate forcing gases are
excluded as the UNEP LCI guidance recommends those for sensitivity analysis only
Two sources are employed for compiling the SCP-HATrsquos GHG emissions input data The main
dataset was the PRIMAP-hist (PRIMAP ndash Potsdam Realtime Integrated Model for Probabilistic
Assessment of Emissions Paths) developed by the Potsdam Institute for Climate Impact Research
(Guumltschow et al 2019 2016) PRIMAP-hist was selected because of its coverage of long time
series and because it integrates other popular global GHG datasets (eg British Petroleum
Review of World Energy (BP 2014) Carbon Dioxide Information Analysis Center fossil fuel and
industrial CO2 emissions dataset (Boden et al 2015) the EDGAR dataset (Janssens-Maenhout
et al 2019) It includes emissions for the main Kyoto greenhouse gases carbon dioxide (CO2)
methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons
(PFCs)sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3) for the period of 1850 to 2016
The country detail is high including almost all countries considered in the SCP-HAT
The PRIMAP-hist sector categorization is based on the main Intergovernmental Panel on Climate
Change (IPCC) 2006 categories It has been analysed in the literature that too poor sector
resolution in the environmental extension of EE-MRIO models can cause aggregation errors
(Steen-Olsen et al 2014 Su et al 2010) and inclusion of external data for further
disaggregation is recommended (Lenzen 2011) To prevent this aggregation bias the PRIMAP-
hist data is further disaggregated using GHG emissions shares from the EDGAR database which
is maintained by the European Commission Joint Research Centre (JRC) and the Netherlands
Environmental Assessment Agency (PBL) (Janssens-Maenhout et al 2019 Olivier and Janssens-
Maenhout 2012) The shares of the different IPCC categories contributing to the total as reported
by EDGAR were applied to the totals published by PRIMAP-hist and used for SCP-HAT Three
specific EDGAR datasets are utilized the Edgar version 432 the EDGAR version 42 Fast Track
(FT) 2010 and the EDGAR version 42 For CO2 CH4 and N2O and the whole period Edgar
version 432 was used For SF6 the Edgar version 42 was used for the period 1990-1999 and
the Edgar version 42 FT for the period 2000-2010 Edgar shares from version 42 were adjusted
using the same approach as FAOSTAT for compiling their ldquoEmissions by sectorrdquo3 dataset For
HFCs and PFCs the EDGAR version 42 FT 2010 was used and shares from 2000 were assumed
as being equal for the period 1990-1999 For HFCs PFCs and SF6 shares for 2010 from Edgar
FT 2010 were applied for the disaggregation of the years 2011 to 2015 After the disaggregation
of the PRIMAP-hist data the IPCC 2006 categories were allocated to one or more sectors of the
SCP-HAT (ie Eora 26 sectors) The IPCC 2006 sector classification in the SCP-HAT and the
correspondence to the SCP-HAT sectors is provided in Annex V For those categories allocated
to more than one sector the emissions were disaggregated according to the relationship of the
total output of the sectors
Lastly emissions from road transportation from industries and households are recorded together
in PRIMAP-hits and EDGAR which need to be disaggregated for a finer analysis in the SCP-HAT
This was done applying the shares of different industries and households in the overall use of
the category lsquoPetroleum Chemical and Non-Metallic Mineral Productsrsquo as provided in Eora
Raw material use and mineral and fossil resource scarcity
For physical data for raw material extraction data from UN IRP Global Material Flows Database
(UN IRP 2017) are used It includes 13 aggregated raw material categories compiled following
lsquoeconomy-wide material flow accountingrsquo principles (Eurostat 2013 OECD 2008) for 192
countries including most of the countries of the SCP-HAT A full list of the raw material extraction
categories can be found in Annex VI National material extraction is allocated to the three
extractive sectors contained in the Eora26 sector classification ndash lsquoagriculturersquo lsquofishingrsquo and
lsquomining and quarryingrsquo While such a high aggregation of extractive sectors can result in a
distortion of the overall results (de Koning et al 2015 Pintildeero et al 2014) an improvement by
means for instance of allocating the extractions to intermediate users (Giljum et al 2017
Schaffartzik et al 2013 Wiebe et al 2012) ndash eg iron from mining to the steel industry ndash is
implemented in some cases The resulting allocation is sometimes referred as lsquouse extensionrsquo in
contrast to the most common lsquosupply extensionrsquo (further details in Annex I)
3 See httpwwwfaoorgfaostatendataEM
Raw material extraction for abiotic materials is translated into impacts by using the mineral and
fossil resource scarcity characterization factors from the Dutch National Institute for Public Health
and the Environment (RIVM) (Huijbregts et al 2016) The midpoint indicator (ie focussing on
intermediate stage along the impact pathway) for fossil resource scarcity is defined as the ratio
between the energy content of fossil resource x and the energy content of crude oil The unit of
this indicator is kg oil-equivalent and it simply reflects the energy content compared to a kilogram
of oil The characterization method for mineral resource scarcity is Surplus Ore Potential which
expresses the average extra amount of ore to be produced in the future due to the extraction of
1 kg of a mineral resource x In other words this reflects the decrease in ore grade of remaining
reserves The indicator is expressed relative to copper in units of kg Cu-equivalent The
ldquohierarchistrdquo version of this indicator is applied which means that future production is chosen to
be the ultimate recoverable resource For more details see RIVM (Huijbregts et al 2016) An
unweighted average characterization factor for the group of ldquoOther metalsrdquo was derived using
the 25 materials listed in that category in the Global Material Flows Database The resulting
factor was dominated by caesium which is probably higher than realistic In version 11 the
characterization factor for the group of ldquoOther metalsrdquo was updated by using a global-production-
weighted average (averaged over the years 2012-2014 as data for some metals are only
available after 2012) This resulted in a significant reduction of the factor with the main
contributors being mercury magnesium zirconium and hafnium
Land use and potential species loss from land use
The UNEP LCI guidance for LCIA indicators makes an interim recommendation (see UNEP 2016)
for characterization of biodiversity impacts of land use discerning occupation and
transformation based on the method developed by Chaudhary et al (2015) In this first version
of the SCP-HAT only land occupation is included and modelling of land transformation is left for
future tool developments To allow for the application of the recommended characterization
factors inventory data is required for land occupation (m2a) for six land use classes - Annual
crops Permanent crops Pasture Extensive forestry Intensive forestry Urban Annex VII shows
sector correspondence for the land use categories in the SCP-HAT Land use for crops and
pasture is allocated partly to the agriculture sector and partly to final demand The allocation to
final demand is made based on data on subsistence and low-input crop farming derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) For details on the
allocation methodology see Annex XXI Land use for intensive forestry is allocated to the wood
and paper industry (ie allocation to first intermediate users see Annex I) Land use for
extensive forestry is allocated partly to the wood and paper industry and partly to final demand
based on domestic wood fuel production and consumption statistics For details on the allocation
methodology see Annex XXI
Land use for other industrial activities than agriculture or forestry (eg mining) is not covered
From version v11 onwards built-up land is allocated directly to final demand and estimated
using OECD land use statistics (OECD 2018)
The definition of the two forestry land use classes used for the impact characterization is i)
Intensive Forest forests with extractive use with either even-aged stands and clear-cut
patches or less than three naturally occurring species at plantingseeding and ii) Extensive
Forests forests with extractive use and associated disturbance like hunting and selective
logging where timber extraction is followed by re-growth including at least three naturally
occurring tree species For the latter alternative uses to wood and paper eg recreation
hunting etc are not considered
Land use data for Annual crops Permanent crops and Pasture are gathered from FAOSTATrsquos
databases for the analogous categories arable land permanent crops and permanent meadows
and pastures (Food and Agriculture Organization of the United Nations 2018) Table 1 shows
data sources and model description for Extensive and Intensive Forestry
Following UNEPrsquos recommendations country-level average characterization factors for global
species loss from Chaudhary et al (2015) are used in the SCP-HAT aggregated over five taxa
(mammals reptiles birds amphibians and vascular plants) for each of the six land use
categories The unit of this indicator is PDFyear which stands for the Potentially Disappeared
Fraction of species for the duration of a year Land use impact modelling assumes that once an
activity (land use) stops the system will slowly return to the natural state The indicator
therefore does not reflect full extinction of species but a temporary decline in biodiversity

Air pollution and health impacts
Many emissions contribute to air pollution via a variety of mechanisms SCP-HAT focuses on air
pollution via particulate matter (PM) which is caused by emissions of PM itself as well as by
emissions of NH3 NOx and SO2 which form so-called secondary PM via chemical reactions The
UNEP LCI guidance for LCIA indicators (UNEP 2016) recommends the use of characterization
factors at end-point reflecting damages to human health expressed in Disability-Adjusted Life
Years (DALY) The recommended approach for calculating DALY impact factors is via emission
source archetypes but this could not be implemented at the global highly aggregated scale of
emissions data used in SCP-HAT The tool therefore uses DALY impact factors from RIVM
(Huijbregts et al 2016) which reflect country-averaged DALY impacts per unit of emission for
each of the four substances (PM25 NH3 SO2 NOx) No differentiation is made by emission source
type at this stage A recent set of new effect factors (Fantke et al 2019) is still only available
at country level without additional distinction of emission source type
The emissions data are taken from the EDGAR database (v432) This database covers all
countries and years up to and including 2012 For emissions of primary PM25 fossil and biogenic
sources are distinguished There is no difference in impact (DALYkg emitted) between those
two categories The data are extrapolated to 2013 and 2015 using GHG emissions trends with a
fixed emission ratio based on 2012 data As shown in Crippa et al (2018) emission ratios of air
pollutants to carbon dioxide have steadily decreased since 1970 but have been relatively stable
since around 2010 especially for NOx and SO2 More specifically PM25 fossil NOx and SO2 are
projected using CO2 emissions trends while CH4 and N2O (in CO2 eq) are used for PM25 bio and
NH3 During data processing it was found that this approach is not satisfactory for NH3 emissions
from agriculture and results are of especially high uncertainty for this category Thus future
improvements should prioritize this specific flow
Socio-economic data
The SCP-HAT includes a set of basic socioeconomic data which mainly serves for the estimation
of relative performance indicators of economies and industries eg carbon per unit of economic
output In the following the data sources used are listed
Population The World Bank Group
GDP The World Bank Group
Value added Eora database
Output Eora database
Employment per sector International Labour Organization
Country groups The World Bank Group
Government and private final consumption Eora database
HDI United Nations Development Programme
Country groups The World Bank Group
Employment by sector and gender is compiled from the ILO (International Labour Organization
2018) The dataset on employment by gender and sector includes only 14 sectors
Disaggregation is done using compensation to employees in Eora as proxy (ie it is assumed
same retribution between sectors belonging to an ILO category)
4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Environmental Assessment Agency (PBL) (Janssens-Maenhout et al 2019 Olivier and Janssens-
Maenhout 2012) The shares of the different IPCC categories contributing to the total as reported
by EDGAR were applied to the totals published by PRIMAP-hist and used for SCP-HAT Three
specific EDGAR datasets are utilized the Edgar version 432 the EDGAR version 42 Fast Track
(FT) 2010 and the EDGAR version 42 For CO2 CH4 and N2O and the whole period Edgar
version 432 was used For SF6 the Edgar version 42 was used for the period 1990-1999 and
the Edgar version 42 FT for the period 2000-2010 Edgar shares from version 42 were adjusted
using the same approach as FAOSTAT for compiling their ldquoEmissions by sectorrdquo3 dataset For
HFCs and PFCs the EDGAR version 42 FT 2010 was used and shares from 2000 were assumed
as being equal for the period 1990-1999 For HFCs PFCs and SF6 shares for 2010 from Edgar
FT 2010 were applied for the disaggregation of the years 2011 to 2015 After the disaggregation
of the PRIMAP-hist data the IPCC 2006 categories were allocated to one or more sectors of the
SCP-HAT (ie Eora 26 sectors) The IPCC 2006 sector classification in the SCP-HAT and the
correspondence to the SCP-HAT sectors is provided in Annex V For those categories allocated
to more than one sector the emissions were disaggregated according to the relationship of the
total output of the sectors
Lastly emissions from road transportation from industries and households are recorded together
in PRIMAP-hits and EDGAR which need to be disaggregated for a finer analysis in the SCP-HAT
This was done applying the shares of different industries and households in the overall use of
the category lsquoPetroleum Chemical and Non-Metallic Mineral Productsrsquo as provided in Eora

lsquoeconomy-wide material flow accountingrsquo principles (Eurostat 2013 OECD 2008) for 192
countries including most of the countries of the SCP-HAT A full list of the raw material extraction
categories can be found in Annex VI National material extraction is allocated to the three
extractive sectors contained in the Eora26 sector classification ndash lsquoagriculturersquo lsquofishingrsquo and
lsquomining and quarryingrsquo While such a high aggregation of extractive sectors can result in a
distortion of the overall results (de Koning et al 2015 Pintildeero et al 2014) an improvement by
means for instance of allocating the extractions to intermediate users (Giljum et al 2017
Schaffartzik et al 2013 Wiebe et al 2012) ndash eg iron from mining to the steel industry ndash is
implemented in some cases The resulting allocation is sometimes referred as lsquouse extensionrsquo in
contrast to the most common lsquosupply extensionrsquo (further details in Annex I)
3 See httpwwwfaoorgfaostatendataEM
Raw material extraction for abiotic materials is translated into impacts by using the mineral and
fossil resource scarcity characterization factors from the Dutch National Institute for Public Health
and the Environment (RIVM) (Huijbregts et al 2016) The midpoint indicator (ie focussing on
intermediate stage along the impact pathway) for fossil resource scarcity is defined as the ratio
between the energy content of fossil resource x and the energy content of crude oil The unit of
this indicator is kg oil-equivalent and it simply reflects the energy content compared to a kilogram
of oil The characterization method for mineral resource scarcity is Surplus Ore Potential which
expresses the average extra amount of ore to be produced in the future due to the extraction of
1 kg of a mineral resource x In other words this reflects the decrease in ore grade of remaining
reserves The indicator is expressed relative to copper in units of kg Cu-equivalent The
ldquohierarchistrdquo version of this indicator is applied which means that future production is chosen to
be the ultimate recoverable resource For more details see RIVM (Huijbregts et al 2016) An
unweighted average characterization factor for the group of ldquoOther metalsrdquo was derived using
the 25 materials listed in that category in the Global Material Flows Database The resulting
factor was dominated by caesium which is probably higher than realistic In version 11 the
characterization factor for the group of ldquoOther metalsrdquo was updated by using a global-production-
weighted average (averaged over the years 2012-2014 as data for some metals are only
available after 2012) This resulted in a significant reduction of the factor with the main
contributors being mercury magnesium zirconium and hafnium
Land use and potential species loss from land use
The UNEP LCI guidance for LCIA indicators makes an interim recommendation (see UNEP 2016)
for characterization of biodiversity impacts of land use discerning occupation and
transformation based on the method developed by Chaudhary et al (2015) In this first version
of the SCP-HAT only land occupation is included and modelling of land transformation is left for
future tool developments To allow for the application of the recommended characterization
factors inventory data is required for land occupation (m2a) for six land use classes - Annual
crops Permanent crops Pasture Extensive forestry Intensive forestry Urban Annex VII shows
sector correspondence for the land use categories in the SCP-HAT Land use for crops and
pasture is allocated partly to the agriculture sector and partly to final demand The allocation to
final demand is made based on data on subsistence and low-input crop farming derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) For details on the
allocation methodology see Annex XXI Land use for intensive forestry is allocated to the wood
and paper industry (ie allocation to first intermediate users see Annex I) Land use for
extensive forestry is allocated partly to the wood and paper industry and partly to final demand
based on domestic wood fuel production and consumption statistics For details on the allocation
methodology see Annex XXI
Land use for other industrial activities than agriculture or forestry (eg mining) is not covered
From version v11 onwards built-up land is allocated directly to final demand and estimated
using OECD land use statistics (OECD 2018)
The definition of the two forestry land use classes used for the impact characterization is i)
Intensive Forest forests with extractive use with either even-aged stands and clear-cut
patches or less than three naturally occurring species at plantingseeding and ii) Extensive
Forests forests with extractive use and associated disturbance like hunting and selective
logging where timber extraction is followed by re-growth including at least three naturally
occurring tree species For the latter alternative uses to wood and paper eg recreation
hunting etc are not considered
Land use data for Annual crops Permanent crops and Pasture are gathered from FAOSTATrsquos
databases for the analogous categories arable land permanent crops and permanent meadows
and pastures (Food and Agriculture Organization of the United Nations 2018) Table 1 shows
data sources and model description for Extensive and Intensive Forestry
Following UNEPrsquos recommendations country-level average characterization factors for global
species loss from Chaudhary et al (2015) are used in the SCP-HAT aggregated over five taxa
(mammals reptiles birds amphibians and vascular plants) for each of the six land use
categories The unit of this indicator is PDFyear which stands for the Potentially Disappeared
Fraction of species for the duration of a year Land use impact modelling assumes that once an
activity (land use) stops the system will slowly return to the natural state The indicator
therefore does not reflect full extinction of species but a temporary decline in biodiversity

Air pollution and health impacts
Many emissions contribute to air pollution via a variety of mechanisms SCP-HAT focuses on air
pollution via particulate matter (PM) which is caused by emissions of PM itself as well as by
emissions of NH3 NOx and SO2 which form so-called secondary PM via chemical reactions The
UNEP LCI guidance for LCIA indicators (UNEP 2016) recommends the use of characterization
factors at end-point reflecting damages to human health expressed in Disability-Adjusted Life
Years (DALY) The recommended approach for calculating DALY impact factors is via emission
source archetypes but this could not be implemented at the global highly aggregated scale of
emissions data used in SCP-HAT The tool therefore uses DALY impact factors from RIVM
(Huijbregts et al 2016) which reflect country-averaged DALY impacts per unit of emission for
each of the four substances (PM25 NH3 SO2 NOx) No differentiation is made by emission source
type at this stage A recent set of new effect factors (Fantke et al 2019) is still only available
at country level without additional distinction of emission source type
The emissions data are taken from the EDGAR database (v432) This database covers all
countries and years up to and including 2012 For emissions of primary PM25 fossil and biogenic
sources are distinguished There is no difference in impact (DALYkg emitted) between those
two categories The data are extrapolated to 2013 and 2015 using GHG emissions trends with a
fixed emission ratio based on 2012 data As shown in Crippa et al (2018) emission ratios of air
pollutants to carbon dioxide have steadily decreased since 1970 but have been relatively stable
since around 2010 especially for NOx and SO2 More specifically PM25 fossil NOx and SO2 are
projected using CO2 emissions trends while CH4 and N2O (in CO2 eq) are used for PM25 bio and
NH3 During data processing it was found that this approach is not satisfactory for NH3 emissions
from agriculture and results are of especially high uncertainty for this category Thus future
improvements should prioritize this specific flow
Socio-economic data
The SCP-HAT includes a set of basic socioeconomic data which mainly serves for the estimation
of relative performance indicators of economies and industries eg carbon per unit of economic
output In the following the data sources used are listed
Population The World Bank Group
GDP The World Bank Group
Value added Eora database
Output Eora database
Employment per sector International Labour Organization
Country groups The World Bank Group
Government and private final consumption Eora database
HDI United Nations Development Programme
Country groups The World Bank Group
Employment by sector and gender is compiled from the ILO (International Labour Organization
2018) The dataset on employment by gender and sector includes only 14 sectors
Disaggregation is done using compensation to employees in Eora as proxy (ie it is assumed
same retribution between sectors belonging to an ILO category)
4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10
Land use and potential species loss from land use
Allocation allocation to households implemented for land use for annual crops permanent
crops pasture and extensive forestry
Bug fixes intensive and extensive forestry labels flipped in v10 for ldquoconsumption
footprintrdquo approach and environmental trends graphs
Country classification
Approach Homogenization of the approach for states that entered in existence or
disappeared within the time period considered in SCP-HAT this refers to ex-soviets
countries former Yugoslavia former Czechoslovakia Ethiopia-Eritrea and Sudan and
South Sudan Only currently existing countries are displayed
User interface
Bug fixes Graphs didnrsquot re-scale when a environmental sub-category is isolated (eg CH4
emissions) was selected in v10 (in ldquoEnvironmental Trendsrdquo and ldquoTrends by sectorrdquo) in
Module 2 Hotspots Identification Further simultaneous data filtering and plotting were not
supported in v10 Module 3 National Data System
Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

httpsdatagovaudatadatasetland-use-of-australia-version-3-28093-20012002
of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Raw material extraction for abiotic materials is translated into impacts by using the mineral and
fossil resource scarcity characterization factors from the Dutch National Institute for Public Health
and the Environment (RIVM) (Huijbregts et al 2016) The midpoint indicator (ie focussing on
intermediate stage along the impact pathway) for fossil resource scarcity is defined as the ratio
between the energy content of fossil resource x and the energy content of crude oil The unit of
this indicator is kg oil-equivalent and it simply reflects the energy content compared to a kilogram
of oil The characterization method for mineral resource scarcity is Surplus Ore Potential which
expresses the average extra amount of ore to be produced in the future due to the extraction of
1 kg of a mineral resource x In other words this reflects the decrease in ore grade of remaining
reserves The indicator is expressed relative to copper in units of kg Cu-equivalent The
ldquohierarchistrdquo version of this indicator is applied which means that future production is chosen to
be the ultimate recoverable resource For more details see RIVM (Huijbregts et al 2016) An
unweighted average characterization factor for the group of ldquoOther metalsrdquo was derived using
the 25 materials listed in that category in the Global Material Flows Database The resulting
factor was dominated by caesium which is probably higher than realistic In version 11 the
characterization factor for the group of ldquoOther metalsrdquo was updated by using a global-production-
weighted average (averaged over the years 2012-2014 as data for some metals are only
available after 2012) This resulted in a significant reduction of the factor with the main
contributors being mercury magnesium zirconium and hafnium
Land use and potential species loss from land use
The UNEP LCI guidance for LCIA indicators makes an interim recommendation (see UNEP 2016)
for characterization of biodiversity impacts of land use discerning occupation and
transformation based on the method developed by Chaudhary et al (2015) In this first version
of the SCP-HAT only land occupation is included and modelling of land transformation is left for
future tool developments To allow for the application of the recommended characterization
factors inventory data is required for land occupation (m2a) for six land use classes - Annual
crops Permanent crops Pasture Extensive forestry Intensive forestry Urban Annex VII shows
sector correspondence for the land use categories in the SCP-HAT Land use for crops and
pasture is allocated partly to the agriculture sector and partly to final demand The allocation to
final demand is made based on data on subsistence and low-input crop farming derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) For details on the
allocation methodology see Annex XXI Land use for intensive forestry is allocated to the wood
and paper industry (ie allocation to first intermediate users see Annex I) Land use for
extensive forestry is allocated partly to the wood and paper industry and partly to final demand
based on domestic wood fuel production and consumption statistics For details on the allocation
methodology see Annex XXI
Land use for other industrial activities than agriculture or forestry (eg mining) is not covered
From version v11 onwards built-up land is allocated directly to final demand and estimated
using OECD land use statistics (OECD 2018)
The definition of the two forestry land use classes used for the impact characterization is i)
Intensive Forest forests with extractive use with either even-aged stands and clear-cut
patches or less than three naturally occurring species at plantingseeding and ii) Extensive
Forests forests with extractive use and associated disturbance like hunting and selective
logging where timber extraction is followed by re-growth including at least three naturally
occurring tree species For the latter alternative uses to wood and paper eg recreation
hunting etc are not considered
Land use data for Annual crops Permanent crops and Pasture are gathered from FAOSTATrsquos
databases for the analogous categories arable land permanent crops and permanent meadows
and pastures (Food and Agriculture Organization of the United Nations 2018) Table 1 shows
data sources and model description for Extensive and Intensive Forestry
Following UNEPrsquos recommendations country-level average characterization factors for global
species loss from Chaudhary et al (2015) are used in the SCP-HAT aggregated over five taxa
(mammals reptiles birds amphibians and vascular plants) for each of the six land use
categories The unit of this indicator is PDFyear which stands for the Potentially Disappeared
Fraction of species for the duration of a year Land use impact modelling assumes that once an
activity (land use) stops the system will slowly return to the natural state The indicator
therefore does not reflect full extinction of species but a temporary decline in biodiversity

Air pollution and health impacts
Many emissions contribute to air pollution via a variety of mechanisms SCP-HAT focuses on air
pollution via particulate matter (PM) which is caused by emissions of PM itself as well as by
emissions of NH3 NOx and SO2 which form so-called secondary PM via chemical reactions The
UNEP LCI guidance for LCIA indicators (UNEP 2016) recommends the use of characterization
factors at end-point reflecting damages to human health expressed in Disability-Adjusted Life
Years (DALY) The recommended approach for calculating DALY impact factors is via emission
source archetypes but this could not be implemented at the global highly aggregated scale of
emissions data used in SCP-HAT The tool therefore uses DALY impact factors from RIVM
(Huijbregts et al 2016) which reflect country-averaged DALY impacts per unit of emission for
each of the four substances (PM25 NH3 SO2 NOx) No differentiation is made by emission source
type at this stage A recent set of new effect factors (Fantke et al 2019) is still only available
at country level without additional distinction of emission source type
The emissions data are taken from the EDGAR database (v432) This database covers all
countries and years up to and including 2012 For emissions of primary PM25 fossil and biogenic
sources are distinguished There is no difference in impact (DALYkg emitted) between those
two categories The data are extrapolated to 2013 and 2015 using GHG emissions trends with a
fixed emission ratio based on 2012 data As shown in Crippa et al (2018) emission ratios of air
pollutants to carbon dioxide have steadily decreased since 1970 but have been relatively stable
since around 2010 especially for NOx and SO2 More specifically PM25 fossil NOx and SO2 are
projected using CO2 emissions trends while CH4 and N2O (in CO2 eq) are used for PM25 bio and
NH3 During data processing it was found that this approach is not satisfactory for NH3 emissions
from agriculture and results are of especially high uncertainty for this category Thus future
improvements should prioritize this specific flow
Socio-economic data
The SCP-HAT includes a set of basic socioeconomic data which mainly serves for the estimation
of relative performance indicators of economies and industries eg carbon per unit of economic
output In the following the data sources used are listed
Population The World Bank Group
GDP The World Bank Group
Value added Eora database
Output Eora database
Employment per sector International Labour Organization
Country groups The World Bank Group
Government and private final consumption Eora database
HDI United Nations Development Programme
Country groups The World Bank Group
Employment by sector and gender is compiled from the ILO (International Labour Organization
2018) The dataset on employment by gender and sector includes only 14 sectors
Disaggregation is done using compensation to employees in Eora as proxy (ie it is assumed
same retribution between sectors belonging to an ILO category)
4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Land use for other industrial activities than agriculture or forestry (eg mining) is not covered
From version v11 onwards built-up land is allocated directly to final demand and estimated
using OECD land use statistics (OECD 2018)
The definition of the two forestry land use classes used for the impact characterization is i)
Intensive Forest forests with extractive use with either even-aged stands and clear-cut
patches or less than three naturally occurring species at plantingseeding and ii) Extensive
Forests forests with extractive use and associated disturbance like hunting and selective
logging where timber extraction is followed by re-growth including at least three naturally
occurring tree species For the latter alternative uses to wood and paper eg recreation
hunting etc are not considered
Land use data for Annual crops Permanent crops and Pasture are gathered from FAOSTATrsquos
databases for the analogous categories arable land permanent crops and permanent meadows

Following UNEPrsquos recommendations country-level average characterization factors for global
species loss from Chaudhary et al (2015) are used in the SCP-HAT aggregated over five taxa
(mammals reptiles birds amphibians and vascular plants) for each of the six land use
categories The unit of this indicator is PDFyear which stands for the Potentially Disappeared
Fraction of species for the duration of a year Land use impact modelling assumes that once an
activity (land use) stops the system will slowly return to the natural state The indicator
therefore does not reflect full extinction of species but a temporary decline in biodiversity

Air pollution and health impacts
Many emissions contribute to air pollution via a variety of mechanisms SCP-HAT focuses on air
pollution via particulate matter (PM) which is caused by emissions of PM itself as well as by
emissions of NH3 NOx and SO2 which form so-called secondary PM via chemical reactions The
UNEP LCI guidance for LCIA indicators (UNEP 2016) recommends the use of characterization
factors at end-point reflecting damages to human health expressed in Disability-Adjusted Life
Years (DALY) The recommended approach for calculating DALY impact factors is via emission
source archetypes but this could not be implemented at the global highly aggregated scale of
emissions data used in SCP-HAT The tool therefore uses DALY impact factors from RIVM
(Huijbregts et al 2016) which reflect country-averaged DALY impacts per unit of emission for
each of the four substances (PM25 NH3 SO2 NOx) No differentiation is made by emission source
type at this stage A recent set of new effect factors (Fantke et al 2019) is still only available
at country level without additional distinction of emission source type
The emissions data are taken from the EDGAR database (v432) This database covers all
countries and years up to and including 2012 For emissions of primary PM25 fossil and biogenic
sources are distinguished There is no difference in impact (DALYkg emitted) between those
two categories The data are extrapolated to 2013 and 2015 using GHG emissions trends with a
fixed emission ratio based on 2012 data As shown in Crippa et al (2018) emission ratios of air
pollutants to carbon dioxide have steadily decreased since 1970 but have been relatively stable
since around 2010 especially for NOx and SO2 More specifically PM25 fossil NOx and SO2 are
projected using CO2 emissions trends while CH4 and N2O (in CO2 eq) are used for PM25 bio and
NH3 During data processing it was found that this approach is not satisfactory for NH3 emissions
from agriculture and results are of especially high uncertainty for this category Thus future
improvements should prioritize this specific flow
Socio-economic data
The SCP-HAT includes a set of basic socioeconomic data which mainly serves for the estimation
of relative performance indicators of economies and industries eg carbon per unit of economic
output In the following the data sources used are listed
Population The World Bank Group
GDP The World Bank Group
Value added Eora database
Output Eora database
Employment per sector International Labour Organization
Country groups The World Bank Group
Government and private final consumption Eora database
HDI United Nations Development Programme
Country groups The World Bank Group
Employment by sector and gender is compiled from the ILO (International Labour Organization
2018) The dataset on employment by gender and sector includes only 14 sectors
Disaggregation is done using compensation to employees in Eora as proxy (ie it is assumed
same retribution between sectors belonging to an ILO category)
4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10
Land use and potential species loss from land use
Allocation allocation to households implemented for land use for annual crops permanent
crops pasture and extensive forestry

supported in v10 Module 3 National Data System
Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

httpsdatagovaudatadatasetland-use-of-australia-version-3-28093-20012002
of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Air pollution and health impacts
Many emissions contribute to air pollution via a variety of mechanisms SCP-HAT focuses on air
pollution via particulate matter (PM) which is caused by emissions of PM itself as well as by
emissions of NH3 NOx and SO2 which form so-called secondary PM via chemical reactions The
UNEP LCI guidance for LCIA indicators (UNEP 2016) recommends the use of characterization
factors at end-point reflecting damages to human health expressed in Disability-Adjusted Life
Years (DALY) The recommended approach for calculating DALY impact factors is via emission
source archetypes but this could not be implemented at the global highly aggregated scale of
emissions data used in SCP-HAT The tool therefore uses DALY impact factors from RIVM
(Huijbregts et al 2016) which reflect country-averaged DALY impacts per unit of emission for
each of the four substances (PM25 NH3 SO2 NOx) No differentiation is made by emission source
type at this stage A recent set of new effect factors (Fantke et al 2019) is still only available
at country level without additional distinction of emission source type
The emissions data are taken from the EDGAR database (v432) This database covers all
countries and years up to and including 2012 For emissions of primary PM25 fossil and biogenic
sources are distinguished There is no difference in impact (DALYkg emitted) between those
two categories The data are extrapolated to 2013 and 2015 using GHG emissions trends with a
fixed emission ratio based on 2012 data As shown in Crippa et al (2018) emission ratios of air
pollutants to carbon dioxide have steadily decreased since 1970 but have been relatively stable
since around 2010 especially for NOx and SO2 More specifically PM25 fossil NOx and SO2 are
projected using CO2 emissions trends while CH4 and N2O (in CO2 eq) are used for PM25 bio and
NH3 During data processing it was found that this approach is not satisfactory for NH3 emissions
from agriculture and results are of especially high uncertainty for this category Thus future
improvements should prioritize this specific flow
Socio-economic data
The SCP-HAT includes a set of basic socioeconomic data which mainly serves for the estimation
of relative performance indicators of economies and industries eg carbon per unit of economic
output In the following the data sources used are listed
Population The World Bank Group
GDP The World Bank Group
Value added Eora database
Output Eora database
Employment per sector International Labour Organization
Country groups The World Bank Group
Government and private final consumption Eora database
HDI United Nations Development Programme
Country groups The World Bank Group
Employment by sector and gender is compiled from the ILO (International Labour Organization
2018) The dataset on employment by gender and sector includes only 14 sectors
Disaggregation is done using compensation to employees in Eora as proxy (ie it is assumed
same retribution between sectors belonging to an ILO category)
4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10
Land use and potential species loss from land use
Allocation allocation to households implemented for land use for annual crops permanent
crops pasture and extensive forestry
Bug fixes intensive and extensive forestry labels flipped in v10 for ldquoconsumption
footprintrdquo approach and environmental trends graphs
Country classification
Approach Homogenization of the approach for states that entered in existence or
disappeared within the time period considered in SCP-HAT this refers to ex-soviets
countries former Yugoslavia former Czechoslovakia Ethiopia-Eritrea and Sudan and
South Sudan Only currently existing countries are displayed
User interface
Bug fixes Graphs didnrsquot re-scale when a environmental sub-category is isolated (eg CH4
emissions) was selected in v10 (in ldquoEnvironmental Trendsrdquo and ldquoTrends by sectorrdquo) in
Module 2 Hotspots Identification Further simultaneous data filtering and plotting were not
supported in v10 Module 3 National Data System
Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied

ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

4 Further developments
The SCP-HAT has been developed to support science-based national policy frameworks SCP-
HATv10 as finalised by the end of 2018 is a full-fledged online tool coming up to the overall
requirements of identifying for all countries in the world for the main policy topics those areas
(ie hotspots) where political action towards a more sustainable consumption and production is
needed However due to time and budget restrictions a number of methodological simplifications
had to been accepted which could be tackled in future developments of the SCP-HAT In the
following the main areas of future improvements are described ndash first identifying possible
shortcomings and then describing necessary development steps
Increasing sectorproduct coverage
Sectoral resolution in EE-MRIO can cause significant impacts in results and having a more
detailed classification would be in general preferable Expanding computing capacity would
allow use of more detailed databases eg the full Eora version with a twofold benefit
minimizing biases and providing wider analytical options Similarly the number of products
covered could be increased eg by providing more detail on primary commodity and
environmentally-intensive imports Following the concept of a lsquohybridrsquo calculation approach
these types of imports could be combined with detailed coefficients derived from LCA ie
coefficients expressing the environmental pressuresimpact per tonne of imported product
instead of per $ of imported product as done in the first version of SCP-HAT Product groups
such as primary products (ISIC Rev4 01 to 09) electricity and gas (ISIC Rev4 35) and waste
collection and materials recovery (ISIC Rev4 38) could be treated in this detailed way while for
manufactured goods with complex supply chains as well as for services the coefficients would
still be calculated using the monetary MRIO model (Pintildeero et al 2018)
Including national data providing default data
Another aspect of further development refers to the inclusion of additional national data For
example the default input-output table provided by the Eora database in the basic version could
be replaced by a national input-output table in order to improve the accuracy of allocating
domestic and imported environmental pressures and impacts to final demand Also the default
data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

data on environmental indicators stem from international data sources which not always build
upon officially reported data In these cases data are reported by experts or have to be
homogenised before being could be replaced by data from official sources
Such an approach however would require a very well designed approach not only regarding
data collection but also data validation While currently Module 3 can be seen as a means to
allow users to cross-check their own data in comparison with the data used in the model the
Module could be re-designed to allow for data upload However the data could not be published
immediately as data quality check would be indispensable Experiences of wiki-type
collaborative work in virtual labs are the ideal starting point for implementing this tool
development (see Lenzen et al 2017) Finally users could be provided with the option of
downloading (sections of) the underlying data to enable them to carry out direct data
comparisons
Automated data updates
The SCP-HAT is developed to allow an easy and quick data updating of different data inputs and
app components This is an important issue considering the fast development of the databases
and models that are employed For instance it can be expected that the Eora database migrates
soon from old product and industry classifications to more updated ones (eg from CPC (Central
Product Classification) Ver1 to CPC Ver2) Also new methods and recommendations regarding
LCIA models can be expected for example the UN Environment Life Cycle Initiative is currently
working on an impact category lsquomineral primary resourcesrsquo that could be incorporated to the
SCP-HAT next versions
While some of these updates might be automated (ie by retrieving the new data automatically
from the original source) data manipulation and incorporation into the model will require
additional work
Improving land use accounts
Land transformation is known to be an important factor contributing to biodiversity loss
Including this next to the impact of land occupation in SCP-HAT would give visibility of a
significant environmental issue No international databases on land transformation exist but the
necessary data could be generated from annual changes in land use The challenge is that for
transformation both the pre- and the post-transformation state of land use need to be known
This requires analysis of likely scenarios of transformation for each country based on average
land cover Existing methodologies such as the one applied in the tool accompanying PAS2050-
12012 may be used as a basis for an approach suitable for SCP-HAT
The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

The current land use (occupation) accounts in SCP-HAT are robust but improved characterization
factors (CFs) for biodiversity are available (Chaudhary and Brooks 2018) These CFs can be
implemented in SCP-HAT but this would require the land use accounts to be revised to
distinguish the necessary land use categories which are somewhat different from those in the
current version There is also a different biodiversity assessment framework (see Di Marco et al
2019) which may be further developed to give state-of-the-art biodiversity CFs Either approach
is likely to give a significant improvement in the biodiversity foot print compared to SCP-HAT 11
which follows the interim UNEP LCI recommended CFs (Chaudhary et al 2015) It should be
noted that the new CFs by Chaudhary and Brooks (2018) are adopted as being in line with the
UNEP LCI recommendation in the draft FAO LEAP guideline for biodiversity impact assessment
of livestock systems (FAO 2019) and as such might be adopted in SCP-HAT without creating
conflict with the UNEP LCI recommendations (UNEP 2016)
Improving approach on air pollutionDALY
In 2019 publication of improved characterization factors for air pollution by particulate matter
are foreseen (Peter Fantke private communication) These new factors would allow to
differentiate impacts by region (continental or subcontinental) as well as by emission source
archetype This would allow for more detailed assessment of hotspots acknowledging that
emissions from eg transport have higher impacts than the same emission from a power plant
Improving emission accounts and their linkages to the EE-MRIO
framework
GHG national inventories (and databases based on them as PRIMAP-hist) follow the territory
principle that is all emissions occurring within the boundaries of a country are accounted In
contrast input-output databases follow the residence principle ie output by the residence units
irrespective from the country where they occur are accounted Although in most cases a resident
unit operates on the domestic territory there are some exceptions such as air and maritime
transportation and combining both approaches with any prior adjustment can lead to some
inconsistencies (Usubiaga and Acosta-Fernaacutendez 2015) However reducing this gap would have
required extra data and assumptions which due to time limitations were out of scope of the
present project Existing approaches for converting GHG accounts from following the territory
principle to residence one could be applied in future versions
Including new category water
Water is an essential resource both for our ecosystems as well as for our societies SDG 6 (Clean
water and sanitation) is tackling the resource water directly while other SDGs are closely related
While the relevance of the topic is clear introducing a water section in Module 1 as well as the
related indicators in the other modules was not possible for different reasons (1) Data
availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 9 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic (light blue) and foreign (dark blue) production from Frischknecht et al (2018)
Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

availability ndash freely available datasets on national water abstraction consumption or pollution
are scarce The AQUASTAT dataset is very patchy and it is not always clear which concepts
have been used which makes it difficult to apply LCIA scarcity indicators such as AWARE (Boulay
et al 2018) More comprehensive datasets like results from the WaterGAP model (Floumlrke et al
2013) require more efforts in compilation than would have been possible for SCP-HAT v1 (2)
Time and budget restrictions ndash the decision was taken to prioritaise a section on pollution instead
However in future stages of tool development including an additional category on water is
indispensable
Include more socio-economic data
In order to allow for more comparisons of the ecological with the socio-economic dimension
further data and indicators are needed Among these would be financial investments financial
costs associated with environmental pressures impacts child labour associated with specific
sectors etc However it has to be investigated if such data are available from official sources
and if they cover all countries world-wide
Technical set-up of SCP-HAT
The app was coded to a large extent using R shiny (httpswwwrstudiocomproductsshiny)
a powerful web framework for building web R-language based applications which is the main
programming language used by the SCP-HAT developing team Once a module is started the
data are loaded and after a country is selected R shiny visualises the pre-calculated data
according to the (sub-) modules chosen In Module 3 inserted data are incorporated into the
underlying MRIO-model and the whole model runs real time calculations to produce the new
results to be visualised While in general the app performs satisfactorily depending on the
necessary calculation procedure some features show poor performance (eg first start-up of
modules computing time for plotting up to a minute for specific visualisations slow IO
calculations with domestic data) In future versions in-depth assessments should be carried out
towards increasing overall app operating capacity
A possibility to improve the performance without changing the code so much would be to move
the hosting of the RStudio Server from shinyappsio to a dedicated server with more capacity
Furthermore all data is now loaded on start-up (see above) which slows down the operation ndash
an option here is to move the data to a database that enables faster start-up and a more
lightweight application instance This is a labour-intensive process also requiring additional
technical infrastructure to be set up which is why the current set-up has been chosen to stay
within the time and budget constraints
In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10

supported in v10 Module 3 National Data System
Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

Pastures
In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

In addition the website the app is embedded in is based on an adapted Wordpress install with
an open source theme that contains an advanced visual editor This means that smaller content
changes can be done quite easily while larger adaptations should only be done using a broader
web-design process that focuses on a clean and efficient user experience Setting up such a web-
design process should be foreseen for the next development phase of the tool
Implement user guidance
The app as well as the website tries to keep the interfaces and functionalities self-explanatory
by using common tried-and-tested usability and interaction design practices Where additional
information is required - such as definitions of expert technical vocabulary - it is placed context-
dependent where needed (A short glossary is also provided in Annex XIX) In addition a
document is provided containing non-technical guidance on how to use the SCP-HAT and how to
interpret results
To increase user guidance user friendliness and applicability in policy processes a state-of-the
art option is to include for each module short explanatory videos which introduce the main
features and explain the main options of use An additional option is to record a series of
webinars where possible results are discussed and options for policy application of the different
analyses are shown

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2

comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts

perspective on focus

Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10
Land use and potential species loss from land use
Allocation allocation to households implemented for land use for annual crops permanent
crops pasture and extensive forestry
Bug fixes intensive and extensive forestry labels flipped in v10 for ldquoconsumption
footprintrdquo approach and environmental trends graphs
Country classification
Approach Homogenization of the approach for states that entered in existence or
disappeared within the time period considered in SCP-HAT this refers to ex-soviets
countries former Yugoslavia former Czechoslovakia Ethiopia-Eritrea and Sudan and
South Sudan Only currently existing countries are displayed
User interface
Bug fixes Graphs didnrsquot re-scale when a environmental sub-category is isolated (eg CH4
emissions) was selected in v10 (in ldquoEnvironmental Trendsrdquo and ldquoTrends by sectorrdquo) in
Module 2 Hotspots Identification Further simultaneous data filtering and plotting were not
supported in v10 Module 3 National Data System
Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10
Land use and potential species loss from land use
Allocation allocation to households implemented for land use for annual crops permanent
crops pasture and extensive forestry
Bug fixes intensive and extensive forestry labels flipped in v10 for ldquoconsumption
footprintrdquo approach and environmental trends graphs
Country classification
Approach Homogenization of the approach for states that entered in existence or
disappeared within the time period considered in SCP-HAT this refers to ex-soviets
countries former Yugoslavia former Czechoslovakia Ethiopia-Eritrea and Sudan and
South Sudan Only currently existing countries are displayed

supported in v10 Module 3 National Data System
Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case
4 ABARES 2018 National Land Use Summary Statistics 2000-2001 version 2018-04-12
httpsdatagovaudatadatasetland-use-of-australia-version-3-28093-20012002
of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10
Land use and potential species loss from land use
Allocation allocation to households implemented for land use for annual crops permanent
crops pasture and extensive forestry
Bug fixes intensive and extensive forestry labels flipped in v10 for ldquoconsumption

supported in v10 Module 3 National Data System
Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

httpsdatagovaudatadatasetland-use-of-australia-version-3-28093-20012002
of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries

to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex I Mathematical description
In this description the nomenclature introduced in the System of Environmental-Economic
Accounting (SEEA) 2012 (European Commission et al 2017) is followed and the reader is
referred to that document for further method details Table 1 shows the main components of a
two countries EE-MRIO model Using matrix notation 119885 records intermediate deliveries
between industries of each country 119910 is the final demand of products and 119907 is value added in
production (or payments to suppliers of primary inputs) Sub-indexes A and B denote the
country of origin or the country of origin and destination (ie 119910119860119861 records final demand of
products from country A consume by country B) In the input-output system total output must
be equal to total input per sector Total output 119909 equals intermediate consumption plus final
demand that is 119909 = 119885119894 + 119910 whereas total input 119909prime equals all inter-industry purchases plus value
added 119909prime = 119894prime119885 + 119907 In the EE-MRIO the monetary framework is expanded to include exchanges
between the natural and socioeconomic systems measured in physical units This is
represented by 119903 which accounts for physical flows by industry (inputs to the system such as
raw material extracted in tons or outputs eg CO2 emissions in kg) Capital and minor letters
denote matrix and column-vector respectively and 119894 is a vector of ones The general
expression of the EE-MRIO model is presented in equation 1
120567 = 120575prime(119868 minus 119860)minus1119910 = 120575prime119871119910 = 120572prime119910 (1)
where 120567 is the consumption-based or footprint for a given final demand 119910 The allocation to
final demand is calculated using the Multipliers 120572 obtained multiplying the Leontief inverse 119871 =
(119868 minus 119860)minus1 whose elements indicates total input requirements per unit of final demand of
products and the environmental pressure intensity 120575prime which expresses physical flows per unit
of industry output and calculated following 120575prime = 119903prime119902minus1 119868 is the identity matrix and 119860 = 119885119909minus1 is the
direct input coefficients matrix
The equation 1 shows the generic expression for EE-MRIO models and it corresponds with the
lsquosupply extensionrsquo that is environmental intensities refer to the industry supplying products
whose production causes environmental pressure directly (eg sand and gravel extraction is
allocated to the mining and quarrying sector) However when the sectoral resolution of the EE-
MRIO model is low allocating the environmental pressures to intermediate consumers (ie
using a lsquouse extensionrsquo) can be an acceptable solution for preventing aggregation errors
(Giljum et al 2017) (eg sand and gravel extracted is allocated to the construction sector)
This can be performed using a supply-to-use conversion matrix 119872 whose elements are zeros
and ones appropriately placed so the general expression is slightly modified
120567 = 120575prime119872119871119910 (2)
In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

In practice it may be also convenient to combine both logics in a mixed approach Accordingly
which perspective provides more satisfactory results need to be assessed in a case by case
basis
Further equation 1 can be further developed for applying LCIA characterization factors 120573
which convert physical flows (ie environmental pressures) to environmental impacts for
example from km2 land use to number of species loss This expansion is shown in equation 3
120567 = 120573prime120575119871119910 (3)
Lastly in EE-MRIO trade and international dependencies in terms of natural resources and
environmental impacts can also be assessed for each countryrsquos final demand bundle 119910
However since in EE-MRIO trade of intermediates is endogenized EE-MRIO trade balances
refer exclusively to indirect and direct pressures and impacts of final products (Cadarso et al
2018 Kanemoto et al 2015) As a consequence EE-MRIO trade balances arenrsquot directly
comparable to conventional bilateral trade balances

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10
Land use and potential species loss from land use
Allocation allocation to households implemented for land use for annual crops permanent
crops pasture and extensive forestry
Bug fixes intensive and extensive forestry labels flipped in v10 for ldquoconsumption

Country classification
Approach Homogenization of the approach for states that entered in existence or
disappeared within the time period considered in SCP-HAT this refers to ex-soviets

supported in v10 Module 3 National Data System
Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

Pastures
In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

httpsdatagovaudatadatasetland-use-of-australia-version-3-28093-20012002
of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10
Materials
Impacts characterization factor for Other metals using weighted average instead of
unweighted average in v10
Land use and potential species loss from land use
Allocation allocation to households implemented for land use for annual crops permanent
crops pasture and extensive forestry
Bug fixes intensive and extensive forestry labels flipped in v10 for ldquoconsumption
footprintrdquo approach and environmental trends graphs
Country classification
Approach Homogenization of the approach for states that entered in existence or
disappeared within the time period considered in SCP-HAT this refers to ex-soviets
countries former Yugoslavia former Czechoslovakia Ethiopia-Eritrea and Sudan and
South Sudan Only currently existing countries are displayed
User interface
Bug fixes Graphs didnrsquot re-scale when a environmental sub-category is isolated (eg CH4
emissions) was selected in v10 (in ldquoEnvironmental Trendsrdquo and ldquoTrends by sectorrdquo) in
Module 2 Hotspots Identification Further simultaneous data filtering and plotting were not
supported in v10 Module 3 National Data System
Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts

Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

Pastures
In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 9 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic (light blue) and foreign (dark blue) production from Frischknecht et al (2018)
Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 9 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic (light blue) and foreign (dark blue) production from Frischknecht et al (2018)
Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint

The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex IX Glossary of SCP-HAT
Indicator this term refers to the environmental and socioeconomic variables which are
included in the SCP-HAT Indicators available in the SCP-HAT are
Environmental indicators
o Raw material use
o Land use (occupation only)
o Mineral resource scarcity
o Fossil resource scarcity
o Short-term climate change
o Long-term climate change
o Potential species loss from land use
o Damage to human health from particulate matter
Socio-economic indicators
o Final demand
o Government final consumption
o Private final consumption
o Employment (total)
o Employment (women)
o Employment (men)
o Output
o Value added
Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output
Annex X Changes between SCP-HAT v10 (release
December 2018) and SCP-HAT v11 (release October
2019)
Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for
Climate Change (ie update to PRIMAP-hist v20 and Edgar 432) also applied for air
pollution
Bug fixes emissions assigned to final consumption in ldquodomestic productionrdquo were not
included in v10

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Perspective This term refers to the accounting principles guiding allocation of environmental
pressures and impacts SCP-HAT comprises two perspectives
- Domestic production This perspective equivalent to the so-called ldquoterritorialrdquo
approach allocates environmental pressures and impacts to the nation where
those pressure and impacts physically occur irrespectively where goods and
services are finally consumed Therefore in the frame of SCP this perspective
could be employed for sustainability assessment of certain production
technologies In this approach no allocation to trade products take place
- Consumption footprint This perspective applying EE-IO technique allocates
environmental pressures and impacts to the nation where final consumers
reside irrespectively to where those pressure and impacts physically occur
Therefore in the frame of SCP this perspective could be utilized for
sustainability assessment of consumer lifestyles This approach allows for
defining a Trade balance between importers and exporters of environmental
pressures and impacts
Unit analyses can be performed using different measurement units which depend on the
perspective on focus
Consumption footprint in absolute terms per consumer (ie per capita) per
unit of GDP (Productivity) per unit of area (km2) or per unit of final demand
Domestic production in absolute terms per capita per unit of GDP
(Productivity) per unit of area (km2) per sectoral worker or per unit of sectoral
output

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

2Hoskins pasture SCPHAT pasture
countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Climate Change
Data Underlying data were updated using PRIMAP-hist version 20 instead of version 11
(Guumltschow et al 2017) and employing Edgar 432 for CO2 CH4 and N2O for splitting
emissions among sectors (see section 3 Data sources) As a result of updating to PRIMAP-
hist version 20 the categories Land Use Land Use Change and Forestry emissions are
now excluded
Allocation In v10 IPCC-1A2 GHG emissions were not allocated to Mining and Quarrying
while in v11 a share of these emissions is assigned to Mining and Quarrying using total
sectoral output
Air pollution
Data GHG emissions are used for extrapolating air pollutants for 2013-2015 (previously
for 2013 and 2014 and 2015 were linearly extrapolated) and thus updates described for

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied

entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia

In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005

Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in

Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied
Figure 3 Pasture mapped for year 2000 by Ramankutty et al (2008) which is the basis for EXIOBASE (before NPP cut-off applied by Stadler et al 2018)
ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in
year 2000 in Australia and an additional 23 Mha for grazing of ldquomodified pasturesrdquo Clearly
the EXIOBASE approach applied leads to a significant underestimate of grazing area in the case

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such

It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11

Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Annex XI Land use comparisons
Land use and potential species loss from land use
SCP-HAT uses EORA as a MRIO model FAO Land Use and Forest Research Assessment data as
land use inventory (pressure) data and characterization factors (CF) for potential species loss
(see Chapter 3) The land use inventory data can be compared to the data used in the
environmentally extended MRIO EXIOBASE v3 (Stadler et al 2018) which has also been used
for evaluation of potential species loss by (Marques et al 2019) Cropland areas are very similar
in both data sets Forest areas deviate for many countries and are typically higher in the
EXIOBASE studies (Figure 2) Pasture areas also deviate for many countries and are typically
higher in SCP-HAT Because pasture has a very prominent contribution to the total biodiversity
footprints (production and consumption) in SCP-HAT this is investigated further
Figure 2 Comparison of land use areas for year 2010 for selected large countries and regions showing ratio of area in EXIOBASE studies to area in SCP-HAT Source Stadler et al (2018) and SCP-HAT
Pasture areas
For EXIOBASE permanent pasture areas for livestock production (input into economy) are
derived from satellite data for the year 2000 such as Global Land Cover 2000 (Bartholomeacute and
Belward 2007) This resulted in a considerable reduction in global area compared to FAO land
use data The rationale for deviating from the FAO land use data is that there is inconsistency
in reporting between countries

In a subsequent step areas with a productivity (NPP) below 20gCmsup2yr were also excluded in
EXIOBASE as these areas are not considered suitable for permanent land use (Stadler et al
2018) This step affected Australia primarily reducing the pasture area included in EE-MRIO
from 408 Mha (FAO) to 188 Mha for the year 2000 (Stadler et al 2018) The NPP cut-off used
by EXIOBASE equates to about 0001 dmthaday of grazing pressure assuming no net
increase or decrease of biomass and 50 carbon content of dry matter The National
Inventory Report for Australia (Commonwealth of Australia 2018 Fig 623 therein) shows that
more than 80 of land has a grazing pressure below 0002 dmthaday suggesting some of
this land area might have been below the cut-off applied for EXIOBASE Cattle number maps
(MLA 2019) however show that in these areas at least 5 million head of cattle are being
grazed (this is a conservative estimate)
Taking the map from Ramankutty and colleagues (2008) (Figure 3) before the NPP cut off is
applied the entirety of the Northern Territory is shown as 0 pasture In reality however
cattle numbers in that state are over 2 million head Further evidence is provided by comparing
Figure 3 with Figure 4 which reveals that large areas of extensive and medium intensity
livestock grazing in Australia are not reflected as land use in the Ramankutty map even before
the cut-off is applied

ABARES4 national land use summary statistics list 419 Mha for ldquograzing native vegetationrdquo in

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

of Australia where grazing can be very extensive compared to most countries Even if the
entire lsquoOther Landrsquo category (Stadler et al 2018) is assumed to be grazing land which may
well be the case for Australia given any ldquoOther Landrdquo with tree cover lower than 5 is
attributed to grazing the total still falls well short of the values reported by ABARES and by
FAO (Note that the lsquoOther Landrsquo of EXIOBASE is different from lsquoOther Landrsquo reported by FAO
Note also that assuming the characterization model used in eg (Marques et al 2019) is
adapted to the land use inventory the total species loss results may still be correct) The FAO
land use data for permanent pastures in 2000 is 408 Mha which is also slightly less than the
bottom-up national land use statistics by ABARES but much closer It is clear that Australia
reports ldquograzing native vegetationrdquo as part of the FAO category Permanent Pasture
In SCP-HAT excluding the low productivity grazing land would not be valid First the footprints
for land use are shown as well as the resulting species loss footprints Second the Chaudhary
species loss CF (Chaudhary et al 2015) have been developed using a combination of the
spatial LADA dataset (Nachtergaele 2013) (also based on GLC 2000 but combined with
several other databases see Figure 4) and FAO land use data and the Forest Resource
Assessment for country-level proportions of subcategories of land use While it is hard to
establish how exactly the land use inventory was developed by Chaudhary it looks like there is
a major difference between Figure 3 and Figure 4 regarding the extensive livestock area While
these land areas would be subject to very extensive grazing by most standards the
biodiversity impacts are still considerable
Two ecoregions AA0701 (Arnhem Land) and AA0706 (Kimberley) in Northern Australia have
CFs for pasture land use that are higher than the Australian average and both are mapped
with grazing pressure below 0002 dmthaday The stocking rates and therefore livestock
product output in these areas will be very low but this should be properly reflected in the
national average CF as established by Chaudhary and colleagues (2015) Excluding these areas
from the inventory would result in an underestimate of the total impact
Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

- Perennial crops percentage of subsistence and low input farming is allocated

- Pasture

The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

Figure 4 Pasture mapping for year 2005 LADA (Nachtergaele 2013) basis for
characterization factors of Chaudhary et al (2015) as used for SCP-HAT
Hoskins and colleagues (2016) have calculated new high-resolution global land use maps for
the year 2005 These maps are currently considered the best available (eg Chaudhary and
Brooks 2018) The pasture areas derived from these maps align well with those used in SCP-
HAT with typically less than 10 deviation (Figure 5) For large grazing countries such as
Brazil Argentina China Australia and the USA the deviation is even less than 5
Figure 5 Areas in 1000 km2 of permanent pastures for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
Summarizing the pasture land use data applied in EXIOBASE excludes extensive grazing areas
and therefore does not align with the characterization factors of Chaudhary (Chaudhary et al
2015) To what extent the absolute areas of productive land use underlying the Chaudhary
factors deviate from SCP-HAT land use areas in general is hard to establish The new high-
resolution maps (Hoskins et al 2016) agree well with FAO land use data for pasture areas For
Australia as a test case the absolute areas used in SCP-HAT are more in line with data
reported by other statistical agencies and the meat and livestock industry than those used in
EXIOBASE Hence pasture land use data should not be changed in the current land
usebiodiversity module
Pasture and cropping allocation
In SCP-HAT 10 all pasture and cropping land use was allocated to the agriculture sector This
led to an overestimate of land use associated with trade A correction was made by allocating
subsistence farming and part of low-input farming to final demand Percentages of cropping
land use areas classified as subsistence and low-input crop farming were derived from the
Spatial Production Allocation Model version 2010 (SPAM You et al 2014) at country level
Allocation to final demand should include true subsistence farming as well as farming that
supplies very local markets only Low input farming in certain regions is likely to supply local
markets whereas in other regions it can be fully commercial and feed into export markets For
pasture (livestock) the methodology is particularly complex because no suitable primary data
were found and contexts vary enormously between regions Highly pastoral systems in

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too

This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail

countries such as Mongolia should be considered fully commercial whereas in countries such
as Mali they are almost entirely subsistence
It was assumed that in Europe Asia-Pacific and North America any (semi-) subsistence
livestock farming is likely to be in mixed systems and therefore already covered by the ldquoannual
croprdquo approach For the other countries the assumption is that (semi-) subsistence farming is
a reflection of economic context and therefore likely to be similar for annual crops and livestock
systems This is obviously a rough approximation but an improvement compared to assuming
zero allocation to final demand
The allocation factors were determined as follows
- Annual crops
Advanced economies Latin America former Soviet states and Other
Emerging countries (ie Eastern Europe and Turkey) the percentage of
subsistence farming is allocated to final demand
All other countries the percentage of subsistence and low input farming
is allocated to final demand
- Perennial crops percentage of subsistence and low input farming is allocated
to final demand for all countries
- Pasture
Sub-Saharan Africa Middle East North Africa Latin America allocation
to final demand is assumed to equal the allocation factor for annual crops
Other countries zero allocation to final demand
The choices were made after careful analysis of the data and yield credible results except for a
small number of countries that deviate in level of economic development compared to their
continental peers Examples are Bolivia (low GDP PPP) and Botswana (high GDP PPP) A
finetuning using actual GDP PPP values could be considered The factors as described above
are applied in SCP-HAT 11
Forestry
Land use for forestry (total area) diverges significantly for some countries between EXIOBASE
studies and SCP-HAT (Figure 2) A more comprehensive comparison is given in Figure 6 that
also shows the comparison to FAO land use categories
Figure 6 Comparison of forest land use areas in SCP-HAT Exiobase and FAO Vertical axis has
been cut off at 30 (Mexico Switzerland)
A detailed comparison for forestry is complex because the definitions of extensive and
intensive forestry as required for application of the CF for potential species loss are specific to
SCP-HAT The Exiobase classification of ldquoForest area ndash Forestryrdquo and ldquoOther land ndash Wood Fuelrdquo
only has limited similarity to this (Stadler et al 2018) The FAO land use database aims to
classify forest area by type rather than by use It distinguishes Forest Land Primary Forest
Other naturally regenerated forest and Planted Forest with the last being the only clear use
category Therefore one-on-one correspondence is not expected but at the same time the
comparison gives interesting insights Note that the areas for Exiobase ldquoOther land ndash Wood
Fuelrdquo are not available for comparison
The fact that Exiobase forest land use is close to FAO ldquonon primaryrdquo land use for some
countries such as Brazil Mexico Slovenia and Switzerland suggests that their method picks
up a lot of the area of ldquoOther naturally regenerated forestrdquo It is likely that some of this area
would be reported as ldquoMultiple Use Forestrdquo Global Forest Resource Assessment (GFRA) (FAO
2015) and as such also feed into the SCP-HAT category of Extensive Forestry but not all of it
For instance for Switzerland the Exiobase ldquoForest area ndash Forestryrdquo area is somewhat larger
even than FAO total Forest Land The Swiss country study (Frischknecht R 2018) also uses an
(intensive) forestry area of 12273 km2 for 2015 which is close to FAO total Forest Land This
suggests that both Exiobase and Frischknecht and colleagues allocate even Primary Forest to
the production footprint which may be valid if all forest area is considered to contribute to eg
tourism (possibly in Frischknecht R 2018) but it seems an overestimate for allocation to
Forestry products as in Exiobase Applying the Chaudhary characterization factor (Chaudhary
et al 2015) for intensive forestry to all forest land (possibly in Frischknecht et al 2018) also
seems inappropriate The GFRA reports 3830 km2 of ldquoProduction Forestrdquo for Switzerland
(2015) and zero multiple-use forest FAO Planted Forest area is 1720 km2 (2015)

Countries ranked by SCP-HAT forest area
Comparison of Forest land data
SCPHAT (intensive+extensive) EXIOBASE (Forest land forestry) FAO (All non-primary) FAO2 (Planted forest)
For many countries the SCP-HAT and Exiobase values are close In the current land use
system in SCP-HAT forestry contributes 20 globally to biodiversity footprints A comparison
between SCP-HAT total forestry and the ldquosecondary habitatrdquo category of Hoskins and
colleagues (Hoskins et al 2016) has not been made yet due to resource constraints The
secondary habitat land use category includes areas that are not used for production and
therefore would be expected to give similar to higher values per country than extensive plus
intensive forestry in SCP-HAT
Forestry allocation
In SCP-HAT all extensive and intensive forest land use is allocated to the Wood and Paper
sector (Annex VII) In many countries however some to almost all of the extensive forest
land use may link to wood fuel collection for household use and should therefore be allocated
to final demand Without this allocation to final demand results for land use trade balances
may be flawed because impacts of exports are equal to impacts of domestic production (by
value)
Forest land use may be split into roundwood and fuelwood by using the Forest Harvest Index
(Furukawa et al 2015) This index was developed to calculate forest cover loss but the ratio
between roundwood and fuelwood area is the same for total land use Roundwood is assumed
to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

to link to intensive forestry first assuming that intensive forestry products will all flow into the
formal economy so no allocation directly to households is expected The remainder is linked to
extensive forestry and then the remainder of extensive forestry is assumed to be for fuelwood
sourcing To establish the fraction of fuelwood forestry land use to be allocated to households
UN data on wood fuel production and consumption are used (The latter step is also applied in
Exiobase except they apply it to their satellite ldquoother landrdquo data) The Energy Statistics
Database (dataunorg) gives data for fuel wood production and consumption by households (in
cubic meters) for most countries The ratio of consumption to production is used as the
allocation factor of the remaining extensive forestry area to final demand for countries other
than those listed as Advanced Economies in the World Economic Outlook (IMF 2019) The
assumption underlying this choice is that subsistence-type use of forest land is not included in
the FAO land use database for advanced economies and that most fuel wood consumption by
households will be sourced via commercial channels
The approach yields allocation factors of extensive forest land use to final demand up to 99
(eg Bhutan) The factors have been derived using land use data and fuel wood production and
consumption data for the year 2010 The Forest Harvest Index is only available as an average
over years 2000-2004 This may lead to overestimates of the allocation to final demand for
countries that have been rapidly developing over the period 1990-2015
It should also be noted that countries that only report intensive forestry or no final
consumption of wood fuel will still have all land use allocated to the lsquoWood and Paperrsquo sector
Trade flows
A country-specific study of land use and biodiversity footprints is available for Switzerland
(Frischknecht R 2018) The approach used in that study links physical trade data with life
cycle inventory (LCI) data that feed into the calculation of a land use footprint for imported
goods For domestic production national land use statistics are used This leads to reasonable
agreement between the Swiss country study and SCP-HAT on the biodiversity impacts
associated with domestic production (Figure 7 versus Figure 8) with the main discrepancy in
the forest category (see discussion above)
Figure 7 Biodiversity impact by land use category domestic production Switzerland from Frischknecht et al (2018) Vertical axis unit and land use colour coding same as Figure 8
Figure 8 Biodiversity impact by land use category domestic production Switzerland from SCP-HAT with urban land use added
However when comparing the consumption footprints (Figure 9 versus Figure 10) the values
from SCP-HAT are significantly higher than those from (Frischknecht R 2018) with the
deviation mainly due to the contribution of foreign land use (ie imports)

Figure 10 Biodiversity consumption footprint in picoPDFyr per capita distinguishing contribution from domestic and foreign production from SCP-HAT
This discrepancy is as yet unexplained While it is not unusual that a life cycle assessment
approach (ldquobottom uprdquo) reports lower values than an input-output (ldquotop downrdquo) approach as
the former are not able to cover the complete supply chain of all goods (Lutter et al 2016)
the difference is not expected to be this large In the SCP-HAT results for Switzerland the
contribution of pasture is about 50 which cannot be easily explained when looking at direct
product imports into the country Similarly there is a very large contribution from Madagascar
which cannot be easily explained either when looking at direct product imports from
Madagascar to Switzerland
It is likely that the high sectoral aggregation of EORA which does not distinguish livestock
products from other agricultural products leads to a distortion of the land use profile of
agricultural exports Essentially the land use profile of exports is identical to the land use
profile of domestic production which is not realistic At the global scale this averages out but
for countries that rely heavily on imports of agricultural products this possibly results in too
high values for consumption footprint
Characterization factors
The characterization factors (CF) used in SCP-HAT (as well as in Frischknecht et al 2018) are
recommended to assess biodiversity loss in the UNEP LCIA guidelines However Chaudhary
and Brooks (2018) have published an updated set of CFs for potential species loss using the
maps byn Hoskins and colleagues (2016) Within each land use category the new CFs
differentiate between low medium and high intensity use According to Chaudhary (private
communication) these values for land use and species loss are superior to the (previous) ones
that are recommended by the UNEP LCIA guidelines Given the good agreement between FAO
land use data and the Hoskins maps it would be feasible to change land use and impact
characterization to this newer method if information on low medium and high intensity use is
available for all countries as well as the required data to split up the category ldquosecondary
habitatrdquo into a range of forestry use types The new CFs for pasture and cropping are about a
factor 100 higher than the previous ones CFs for plantation forestry are almost identical to
those for cropping in the new set compared to a factor of 2 or 3 lower in the existing set as
used by SCP-HAT (those recommended in UNEP 2016) Not only would the absolute impacts
increase dramatically but the contribution of forestry would likely be higher The relative
profiles of countries (ie comparison) might not be influenced much
General conclusions
There is good agreement on cropping land use areas between the different studies (Figure 2
and Figure 11)
Figure 11 Areas in 1000 km2 of crop land (arable land) for selected countries year 2005
comparison between SCP-HAT and Hoskins et al (2016)
There is more discrepancy between different databases regarding pasture land use but as
demonstrated above the data used in SCP-HAT is robust and matches the characterization
factors leading to a consistent approach The contribution of pasture land in trade flows is
probably due to the limited sectoral differentiation of EORA (see Chapter 2) This is an intrinsic
limitation in SCP-HAT that needs to be monitored
There is also discrepancy regarding forest land use which would require additional resources to
investigate but note that this category does not typically have a major contribution to country
production or consumption footprints in the current approach For some countries the allocation
of forest land use to the Wood and Paper sector may result in an overestimate of trade balances
(especially export of extensive forestry) which is recommended to address
A more systematic update may be considered for the land use module using the land use map
from (Hoskins et al 2016) in combination with FAO land use data to improve land use data and
combine those with the new characterization factors by (Chaudhary and Brooks 2018) This
needs to be explored in more detail
