Global Forest GHG Emissions and FLR CO2 Removals Databases Winrock International (WI) and the International Union for the Conservation of Nature (IUCN) June 2017 Project Number P02004 / Award Number AVUS-00065
winrock.org
Comprehensive global analysis of emissions and removals from land use change Two databases:
1. Emissions: deforestation & three forest degradation activities
2. Removals: potential removals from four Forest Landscape Restoration (FLR) activities
Emissions and removals offered at both national
and subnational (state/province) levels
Project Description
winrock.org
Project Description Offers consistent, comparable global estimates of
emissions from key REDD+ activities Applied scientifically robust methods and data
(generally consistent with IPCC Tier 2 approach): Global, spatially explicit datasets Published, peer-reviewed literature Nationally reported data
Consistent with methods and data applied in Pearson et al. (2017) Greenhouse gas emissions from tropical forest degradation: an underestimated source. Carbon Balance and Management 12:3 DOI: 10.1186/s13021-017-0072-2

Emissions Database
Deforestation Degradation • Logging (legal) • Woodfuel
collection • Fire
winrock.org
Emissions Database - Methods
Area of forest loss
• Non-Annex 1 Countries: Satellite imagery (Landsat 7 ETM+ and Landsat 8 OLI)
• Annex 1 Countries:
National greenhouse gas inventory reports
Carbon stocks in forests
• Tropics: Saatchi et al. (2011) pantropical map
• Other: Avitabile et al. (2016) global map
Emissions from
deforestation
winrock.org
Emissions Database - Methods
• Pearson et al. 2014 Methodology -- national data on harvest volume combined with values for logging emission factors
Selective Logging
• Woodfuel Integrated Supply/Demand Mapping (WISDOM) model using national and global datasets
Woodfuel Collection
• Global Fire Emissions Database (GFED) (applies MODIS satellite imagery)
Fire

Emissions Database - Results
Global emissions (Mt CO2e yr-1)
winrock.org
Results - Emissions Overall, deforestation emissions are the highest,
followed by logging, woodfuel, and fire. Indonesia and Brazil had highest total emissions by far. Developing countries had higher (land use change)
emissions than developed ones.
winrock.org
Results – Regional Patterns in Emissions Woodfuel
proportionately more significant in Africa Logging proportionately
more significant in Americas Highest total
deforestation emissions in Asia

Results – Emissions from Forest Degradation Significance of degradation activities varies
widely.
Forest degradation emissions in the top 15 degradation emitting countries. Size of the bubble is proportional to emissions for each activity, and color represents regions/continents
(Asia = red, LAC = green, Africa = purple, Europe = blue).
winrock.org
Results - Emissions
Total forest emissions (t CO2e yr-1) from the 15 countries with highest emissions. The size of the bubble is proportional to the country area, and color represents region/continent.
(Asia = red, LAC = green, Africa = purple, Europe = blue).
Country size not necessarily correlated with magnitude of emissions.

Removals Database – FLR Types Land use General category of FLR option Description
Forest land Land where forest is, or is planned to become, the dominant land use
Planted forests and woodlots
Planting of trees on formerly forested land. Native species or exotics and for various purposes, fuel- wood, timber, building, poles, fruit production, etc.
Natural regeneration
Natural regeneration of formerly forested land. Often the site is highly degraded and no longer able to fulfill its past function – e.g. agriculture. If the site is heavily degraded and no longer has seed sources, some planting will probably be required.
Agricultural land Land which is being managed to produce food
Agroforestry
Establishment and management of trees on active agricultural land (under shifting agriculture), either through planting or regeneration, to improve crop productivity, provide dry season fodder, increase soil fertility, enhance water retention, etc.
Protective land and buffers Land that is vulnerable to, or critical in safeguarding against, catastrophic events
Mangrove restoration
Establishment or enhancement of mangroves along coastal areas and in estuaries.
winrock.org
Removals Database CO2 removals developed through a highly
comprehensive review of literature on tree growth Growth curves built by collating data points
from over 144 studies on forest restoration and tree growth For most FLR types, growth rates were
simplified to <20 year and >20 year averages for database
winrock.org
Removals Database - Methods
1. Collect data from published and
unpublished studies on tree growth by FLR type
2. Apply data to Chapman Richards
Growth Model
3. Derive estimates of potential removals by
FLR type

Removals - Results • Potential removals over 20 years if commitments are met.
• Indonesia, Nigeria, and India stand out as having the greatest potential
removals based on their large commitments.
