General Considerations
3.5D.55
Fundamental Distinctions in Mitigation Actions
• Technologies and practices that reduce GHG emissions:– Efficiency (demand, supply)– Substitution (fuels, feedstock, products)– End-of-pipe (carbon capture and storage-CCS)– Practices (farming, land clearing, etc.).
• Policies and instruments that lead to the use of these technologies and practices:– Economic and financial instruments (e.g. taxes and incentives, markets,
trade policy)– Regulatory approaches (e.g. standards, required practices)– Information (e.g. labelling, campaigns) – Capacity building (e.g. institutions, skilled workforce).
3.6D.66
Mitigation Potential and Barriers
• Many barriers may need to be overcome on the path from theoretical to actual use of lower-emission technologies and practices
• Many policy tools are available to help overcome these barriers, and must be tailored to national and local circumstances.

Facilitating Energy Efficiency
• New investments in power, industry, transport and building infrastructure can be substantially more efficient than existing stock
• Economic growth is powering a rapid increase in these sectors, and associated emissions
• Almost all countries exhibit declining energy intensity trends
• Most countries have initiatives to promote energy efficiency in these sectors
• Technology integration, support, and financing risks are high

3.8D.88
General Considerations for Mitigation Strategies
• Overcoming barriers requires a wide variety of policies, measures and instruments.
• Taking advantage of capital stock turnover and periods of rapid social change can minimize disruption and mitigation costs.
• National responses to climate change can be more effective if deployed as a portfolio of policy instruments to limit or reduce GHG gas emissions.
• Effectiveness can be enhanced when climate policies are integrated with the non-climate objectives of national and sectoral policy (e.g., sustainable development).
• Coordinated actions among countries and sectors may help to reduce mitigation costs, address competitiveness concerns and carbon leakage.
• Earlier action can increase flexibility in moving towards stabilization of atmospheric concentrations of greenhouse gases.
3.9D.99
Opportunities for Overcoming Barriers
• Synergies between competitiveness and GHG mitigation (e.g. when GHG mitigation could reduce production costs for industry)
• Good communication strategies (marketing) to encourage consumer acceptance of new technologies
• Better communication among firms, between firms and users, or universities or government labs
• Creation of economic, regulatory and social incentives for reducing GHG emissions
• Changes in the market and legislative context can also provide opportunities for innovation
• Availability of appropriate financial tools.

3.22D.2222
Addressing Energy Supply in a Mitigation Assessment
Mitigation assessments tend to focus on energy supply and choice of fuels and carriers from a sectoral perspective:• In most countries, electricity generation is the principal source of emissions
and the main focus of mitigation assessment for energy supply.• Emissions from fossil fuel production (e.g., coal-bed methane), processing
(refinery technologies), and transport and distribution (T&D ) (pipeline management) are often addressed as part of industrial sector analysis.
• Biomass energy – both traditional and modern – is typically addressed in the relevant consuming sectors: biofuels for transportation, biomass fuels for electricity generation, traditional biomass in residential and agriculture, etc.
• Fuel switching and development of new energy carriers (e.g. hydrogen for vehicles) are typically examined in consuming sectors (e.g. transport).
• However, there is no standard and countries should feel free to take approaches that are appropriate to national institutions and circumstances.
3.23D.2323

– CH4: decomposition of organic materials in anaerobic conditions
– N2O: microbial transformation of nitrogen in soils and manures.
• Key drivers:– Population growth
(escalating demands for food)
– Shifts in diet.
3.78D.7878
Agriculture: Emissions Trends
• 10-12% of total global anthropogenic GHG emissions:– 60% of N2O and 50% of
CH4
– net flux of CO2 roughly balanced.
• Globally, agricultural CH4and N2O emissions have increased nearly 17% from 1990-2005:– Non-Annex I countries
• Showed a 32% increase• Responsible for ~3/4 of
total agricultural emissions by 2005
– Annex I countries• Showed a 12% decrease.
3.79D.7979
Agriculture: Trends and GHG implications
• Continued conversion of forest and other land to agriculture (occurring largely in developing countries)
• Continued growth in land productivity (at a declining rate due to increased use of marginal lands)
– Increasing per-capita food availability despite decreasing per-capita agricultural land, due to technological progress
• Increased use of conservation and zero-tillage• Growing demand for meat and dairy products in developing countries
(driven by economic growth and changing lifestyles)• Intensive production of beef, poultry and pork increasingly common• Increasing international trade due to changing policies and patterns of
production/demand• Increasing use of agricultural products as substitutes for fossil fuel-based
products (e.g. bio plastics, biofuels).

3.81D.8181
Agriculture: Mitigation Technologies and Strategies
• Reducing emissions through improved:– Livestock and manure management– Water and rice management– Fertilizer application– Cultivation methods
• Enhancing removals/creating sinks (carbon sequestration) through:
– Agro-forestry– Set-asides and land-use change– Soil carbon storage– Reduced tillage or no till cropping
• Avoiding (or displacing) emissions– Substituting fossil fuels with energy from
agricultural feed stocks (e.g. crop residues, dung, energy crops)
• (counted in sectors using the energy). Source: FAO MICCA Programme pilot projects: http://www.fao.org/climatechange/micca/70795/en/
3.82D.8282
Selection of Mitigation Measures Depends on…
• Prices for carbon:– Low prices: dominant
strategies consistent with existing production (e.g. changes in tillage, fertilizer application, livestock diet formulation, manure management)
– Higher prices: elicit land-use changes that displace existing production (e.g. biofuels) use of costly animal feed-based mitigation options.
• Location:– Practice effective in
reducing emissions at one site may be less effective (or even counterproductive) elsewhere.

Agriculture: Key Barriers
Key barriers:• Farm-level adoption constraints• Government subsidies• Lack of capacity and skills• Lack of information• Property rights• Transaction costs, measurement
and monitoring costs• Potential for reversibility or
displacement of emissions• Measurement uncertainty• Consistency with traditional
practices• Pressure for competing uses of
land and water.
Overcoming barriers:• Participatory arrangements that fully
engage all the involved actors may help to overcome many barriers
• Expansion of internationally supported credit and savings schemes, and price support, to assist rural people
• Shifts in the allocation of international agricultural research
• Improvement of food security and disaster early warning systems
• Development of institutional linkage between countries with high standards in certain technologies, for example flood control.

LULUCF: Emissions Sources and Trends
• Main source of emissions:– Stored CO2 released through
deforestationLand-use change is a highly complex process. It results from the interaction of diverse drivers that may be direct or indirect and can involve numerous transitions, such as clearing, grazing, cultivation, abandonment and secondary regrowth (Gerber et al. 2013).Deforestation and land-use change accounts for 2,200–6,600 million tonnesof carbon dioxide (CO2) equivalent per year, or 30–50% of agricultural emissions and about 4–14% of global emissions (Vermeulen et al. 2012, based on van der Werf et al. 2010 and Blaser and Robledo 2007).

Mexico Low Carbon Study (MEDEC):Agriculture and Forestry Interventions
Source: World Bank, “Low Carbon Development for Mexico”
The study identified and evaluated interventions in the agriculture and forestry sectors:• Agriculture:
– Zero-tillage maize; biofuel production
• Forestry:– REDD with productive use of
biomass (e.g., biomass electricity, charcoal production)
– REDD without productive use of biomass (e.g. wildlife management, payment for environmental services)
– Reforestation and restoration, afforestation.
Mitigation potential was assessed with a geographic information system.
3.99D.9999
LULUCF: Barriers and Opportunities
Key barriers:• Profitability incentives frequently run
counter to forest conservation and sustainable forest management
• Direct and indirect drivers of deforestation lie outside the forestry sector (e.g., agricultural policies/markets)
• Lack of technical capability, including for monitoring carbon stocks
• Limited regulatory and institutional capacity
• Efficiency of forest policies influenced by land tenure, institutional and regulatory capacity of governments, financial competitiveness, cultural relationship to forests.
Overcoming barriers:• Forestry sector options are relatively
low cost compared with those in the energy sector, which helps to reduce barriers
• Promotion of mitigation projects also promotes the flow of technology
• Independent verification of carbon abatement would help to increase the credibility and funding of forestry-sector mitigation projects.
3.100D.100100
LULUCF: Policies and Measures (Examples from IPCC)
• Reducing deforestation:– Combat illegal logging: legally protect forests by designating protected areas
and reserves– Country successes: significantly reduced deforestation rates in China, the
Philippines, and Thailand; reduced forest degradation through Joint Forest Management programme in India
– Limited options for maintaining forests on private lands (though payment for environmental services (PES) approaches being developed)
– Advantage of national-sectoral approach over project-based to avoid leakage (though still risk of international leakage).
• Promote afforestation and reforestation:– Non-climate forest policies– Incentives for plantation establishment (e.g. afforestation grants, tax exemptions,
etc.)
3.101D.101101
LULUCF: Policies and Measures (Examples from IPCC continued)
• Improve forest management:– Reduce harvest rates and/or damage– Due to limited government authority on private lands, provide incentives to maintain forest
cover or improve management (e.g., tax credits, cost sharing, environmental service payments)
– Increase forest protection against natural disturbance agents (e.g., insects, disease, fire)– Voluntary certification schemes.
• Increase substitution of forest-derived biofuels/biomass for fossil fuels/energy-intensive materials:
– Examples include Brazil’s industrial charcoal production incentives, Australia’s Mandatory Renewable Energy Target incentivizing energy from plantations and wood waste, building codes to promote sustainably construction materials.
• Strengthen role of forest policies in mitigating climate change:– Most successful when: consistent with profitability incentives; or sufficient political will,
financial resources, and regulatory capacity– Climate mitigation generally not the core focus of forestry policies, so leakage and other
factors not often considered– Examples of integration of climate change mitigation objectives into national forestry policies:
Costa Rica, Dominican Republic, Peru.

Waste Management
3.107D.107107
Waste Management
• Key challenges:– Availability and quality of
annual data– Decisions often made
locally without quantification, leading to underestimation of waste sector mitigation globally
– Decoupling generation of waste from economic drivers.
3.108D.108108
Waste Management: Emissions Sources and Drivers
• Major sources of GHG:– Landfill CH4
– Wastewater CH4 and N2O• Other sources:
– Minor CO2 emissions from waste incineration
– Fluorinated gases (CFCs and HCFCs)
• Can persist for decades in post-consumer waste and occur as trace components in landfill gas; not currently quantified
• Key drivers:– Waste generation, which is linked to
population, urbanization, and affluence
– Extent of landfill gas capture.Source: IPCC (2007) AR4 WGIII
3.109D.109109
Waste Management: Regional Variations
• Landfill CH4 emissions– Developed countries:
largely stabilized due to landfill gas recovery, increased recycling, decreased landfilling, alternative waste management technologies
– Developing countries: increasing due to more controlled anaerobic landfilling.
• Wastewater CH4 and N2O emissions:– Generally higher in
developing countries due to rapid population growth/urbanization without concurrent wastewater infrastructure.
3.110D.110110
Waste Management: Mitigation Technologies and Strategies
• Wide range of mature technologies available for waste management:
– Landfill gas recovery (reduces CH4)
– Post-consumer recycling (avoids waste generation)
– Composting (avoids GHG generation)
– Processes reducing GHG generation compared to landfilling
• Thermal processes, e.g. incineration and industrial combustion, MBT with landfilling of residuals, anaerobic digestion
• Advanced thermal processes, e.g. pyrolysis and gasification.

3.111D.111111
Waste Management: Mitigation Technologies and Strategies• Many technologies
available for wastewater management, collection, treatment, re-use and disposal:– Natural purification
processes– Energy-intensive advanced
technologies.
• Wastewater treatment removes pollutants:– Small systems: pit latrines,
composting toilets, septic tanks
– Advanced treatment: sludge treatment, trickling filters, anaerobic or facultative lagoons, anaerobic digestion and constructed wetlands.
3.112D.112112
Waste Example from Ethiopia’s 1st National Communication
• Selection of measures depends on costs and socio-cultural attitudes. Preliminary analysis suggests composting is the cheapest option, followed by landfill methane recovery.
• Composting is promising because 68% by weight of solid waste in Addis Ababa city is organic.

Waste Management: Key Barriers
Key barriers:• Lack of enabling policies
initiatives, institutional mechanism, information and opportunities
• Organizational problems in collection and transport
• Lack of coordination among different groups.
Overcoming barriers• A multi-pronged approach is needed
which should include the following components:
– Building up of databases on availability of wastes, their characteristics, distribution, accessibility, current practices of utilization and/or disposal technologies and their economic viability
– An institutional mechanism for technology transfer though a coordinated programmeinvolving the R&D institutions, financing agencies, and industry (Schwarz, 1997)
– Defining the role of stakeholders including local authorities, individual house holders, NGOs, industries, R&D institutions, and the government.

Waste Management: Questions for Discussion
• To what extent is landfill gas recovery common practice in your country? Is this likely to change in the future?
• The emissions benefits of reuse strategies, both in the formal and informal sectors, as well as waste minimization and recycling activities, may result largely from avoided manufacturing and material extraction emissions. How can these benefits be reflected in mitigation assessments and in future emissions inventories?

Mitigation from a Cross-Sectoral Perspective
3.117D.117117
Types of Cross-Sectoral Mitigation Technologies
• There are various mitigation technologies that affect multiple sectors, or that cannot be attributed to any particular sector.
• Implementation of cross-sectoral mitigation technologies can:– Occur in parallel in more than one sector
• Improvement in one sector will benefit the others– Involve interaction between sectors
• Mitigation potential increased when applied as a group– Create competition among sectors
• May compete for resources.
• Other techniques:– Ocean fertilization and geo-engineering
• Speculative; environmental side-effects and costs still being assessed.
3.118D.118118
Examples of Cross-Sectoral Mitigation Technologies
• Parallel:– Solar PV:
• Centralized energy generation in energy sector; distributed energy generation in buildings sector
– Information technology (IT):• Implemented in parallel across sectors as component of various end-use
technologies (e.g., advanced vehicle technologies, smart household appliances.
• Interaction:– Use of fossil fuel gasification with carbon dioxide capture and storage
(CCS) technology to produce hydrogen for transportation and industrial applications.
• Competition:– Use of biomass for transportation fuels, and competition for land and
resources with other sectors.
3.119D.119119
Cross-Sectoral Mitigation: Linkages, Synergies and Trade-offs
• Synergies and trade-offs between measures with non-climate objectives and GHG mitigation:– Generally, climate mitigation is not the goal; rather,
outgrowth of efforts driven by economic, security, of local environmental concerns
– Promising approaches take advantage of natural synergies between climate protection and development priorities, in order to advance both simultaneously.
3.120D.120120
Cross-Sectoral Mitigation: Questions for Discussion
• What are some key challenges associated with cross-sectoral mitigation approaches (both technologies and policies), both in assessment and in implementation?
• How can an assessment team ensure analytical consistency across many different sectors?
• How can the concepts of mitigation potential (market, economic, social, technological) and barriers best be incorporated into a mitigation assessment?
