AGRICULTURAL GHG EMISSIONS
5
Greenhouse gas emissions from agricultural production and food supply chains total ~20% of emissions
6Sources: FAOStat, EDGAR 4.2, FRA 2012, Harris 2012, Vermeulen 2012, and others.
Global agriculture and land use change emissions
Sources of direct emissions from agriculture
7Source: FAOStat data from 2010 (accessed 2013)
Sources of emissions %
Enteric fermentation Ruminants (e.g., cattle, sheep, goats, water buffalo) emit CH4 directly as a byproduct of digestion.
43%
Manure deposited on grazing lands Manure and urine that falls on grazing lands causes N2O emissions.
16%
Synthetic fertilizers N2O emissions from soils resulting from large amounts of nitrogen fertilizer added to crops.
15%
Rice production Most rice production systems result in CH4 emissions from anaerobic decomposition on flooded fields. This fraction represents CH4 emissions from rice only. N2O emissions from fertilizers are counted above.
11%
Stored manure Livestock manure and urine cause both CH4 emissions through increased decomposition in wet storage systems, as well as N2O emissions in dry storage systems.
7%
Crop residues Crop residues that remain on agricultural lands are a source of N2O.
3%
Manure deposited on croplands Manure is another source of nitrogen fertilizer for crops, resulting in N2O emissions.
2%
Cultivation of organic soils N2O emitted from drained organic soils.
2%
This report focused almost exclusively on direct agricultural emissions. Bioenergy, reduced deforestation, restoration of degraded lands, and restoration of peatlands were all out of scope.
Direct agricultural emissions are spread across regions and across production sectors
8Source: FAOStat data from 2010 (accessed 2013); area of pie charts scaled to regional emissions.
“Ag soils” includes synthetic fertilizers, manure applied to crops, field application of crop residues, and nitrous oxide from cultivated organic soils.
Beef cattle and other ruminants dominate agricultural emissions
9Source: FAOStat data 2008; Gerber et al. 2013; Paul West, Institute on the Environment, University of Minnesota
Beef, dairy, and other ruminant meat account for roughly two-thirds of direct agricultural emissions. Beef, palm, and soy are the largest agricultural-commodity drivers of land use emissions.
AGRICULTURAL GHG MITIGATION

Technical agricultural mitigation potential in 2030
11Source: CEA analysis. See Annex 3 in the full report for methodology.
Note: This waterfall implies that all segments are additive. In fact, they are not and this analysis did not model mitigation potential, but rather looked at discrete opportunities statically.
Mitigation opportunities by country
12Source: CEA analysis. See Annex 3 in the full report for methodology.
Mitigation opportunities are clustered primarily in the major agricultural economies.
Agricultural cost curves all have basically the same structure
13
Representative cost curve
This report provided an assessment of the technical GHG mitigation potential in agriculture. It did not include an economic assessment due to insufficient data. However, the economics of mitigation follow roughly the same pattern in most geographies.

1. SHIFTING CONSUMPTION PATTERNS
18
Overarching Rec 1: Shifting Diets
While numerous researchers and institutions around the world are focused on reducing the carbon footprint of livestock production (supply), little has been done about the viability of curbing growth trajectories of meat consumption (demand).
19
Overarching Rec 1: Shifting Diets

Overarching Rec 1: Shifting Diets
21
Goal Objectives Interventions Reduce meat consumption, primarily of beef, to healthy levels of consumption ~2.15 Gt CO2e per year by 2030
Influence domestic policies in China and the U.S. to reduce demand
Leverage existing food security policies to reduce beef production and imports, and promote alternative proteins in China Promote public health policies that incentivize healthy diets and healthy levels of protein intake in the U.S.
Curb future demand of beef in China and decrease per capita meat consumption in the U.S. through media and outreach campaigns
Expand national campaigns and promote health links in the U.S. Build argument and enhance communications campaigns in China
Overarching Rec 1: Reducing Food Wastage
Approximately one third of all food intended for human consumption is lost or wasted in the value chain (production, handling and storage, processing and packaging, distribution and market, and consumption). The carbon footprint of food wastage is estimated at 3.3 Gt CO2e, making it the third largest source of emissions after the U.S. and China
22
Overarching Rec 1: Reducing Food Wastage
In the developing world, losses mainly occur postharvest as a result of financial and technical limitations in production techniques, storage and transport. In contrast, losses in the developed world are mostly incurred by end consumers.
23
Overarching Rec 1: Reducing Food Wastage
24
Goal Objectives Interventions
Reduce food wastage by 60%> 2 Gt CO2e
Reduce consumer food waste in China and the U.S.
Revise food date labeling practices in the U.S. Support consumer education through communication campaigns
Engage the private sector and reform corporate policies in China and the U.S.
Measure food waste in food companies along the supply chain
Reduce food loss in the value chain by improving handling and storage practices in South/ Southeast Asia and Sub-Saharan Africa
Provide technical and financial support to farmers
2. REDUCE DIRECT AGRICULTURAL EMISSIONS
25
Overarching Rec 2: Sustainable IntensificationIntensification is essential for food security and can contribute to mitigation through improved emissions efficiency. Mitigation benefits depend on: 1) the compound emissions efficiency of production inputs, 2) the rebound effect of intensification
26
Goal Objectives Interventions
Reduce GHG emissions through sustainable intensification
Promote realization of high mitigation intensification opportunities at scale
Assess mitigation effectiveness of intensification strategies in REDD+ finance Develop assessment tools to identify mitigation opportunities with high co-benefits and low / manageable tradeoffs
Overarching Rec 2: Enteric Fermentation Enteric fermentation is responsible for over 40 percent of direct agricultural emissions. Beef and dairy cattle account for roughly two-thirds of all emissions from enteric fermentation. The emissions reduction potential in Brazil, India, the U.S. and E.U. alone amounts to 350Mt CO2e per year.
27
Overarching Rec 2: Enteric Fermentation
28
Goal Objectives Interventions
Reduce GHG emissions from enteric fermentation through improved livestock diets ~940 Mt CO2e per
year
Improve grazing lands management in beef production in Brazil
Promote awareness and capacity of cattle ranchers through outreach and vertical integration of the supply chain Increase effectiveness of the ABC program to reduce agricultural emissions
Improve feeding practices in dairy production in India
Increase adoption of improved practices by making a business case and supporting outreach campaign s to processors , producers and farmers
Overarching Rec 2: Improving nitrogen fertilizer management and production
29
Nitrous oxide emissions stem from nitrogen fertilizers on croplands that have not been absorbed by plants, and leach instead into the environment. Fertilizer run-off contaminates surface and ground water quality and creates GHG emissions in the form of nitrogen oxide. The global technical mitigation potential for reducing nitrous oxide from soils is roughly 325 Mt CO2e.
Goal Objectives Interventions
Reduce GHG emissions from improved fertilizer management and production~485 Mt CO2e per year
Improve fertilizer use and management in China
Evaluate the Soil Testing and Fertilizer Recommendation program in China and additional measures to reduce fertilizer application Support efforts in knowledge dissemination to farmers on correct fertilizer management
Improve fertilizer production in China
Engage the fertilizer industry through investment or outreach
3. CROSS –CUTTING MEASURES
30
Overarching Rec 3: Steer finance towards higher sustainability practices
31
Considering the capital and investment needs of the agricultural sector, it is essential that baseline financial flows into agriculture be re-directed towards low emitting, carbon rich and sustainable agricultural models.
Goal Objectives Interventions
Steer international public funds into low-emissions agriculture
Reduce GHG impact of internationally financed agricultural programs
Steer donor support away from high emitting agricultural activities, especially beef production Include GHG data in investment appraisal and program evaluation
Channel climate finance towards agriculture
Incorporate climate-smart agriculture in design and implementation of the Green Climate Fund
Overarching Rec 3: Subsidies and Trade
32
Goal Objectives Interventions
Create international incentives for GHG reduction and removal
Incentivize GHG mitigation through subsidies reform in the U.S. and the E.U.
Establish financial incentives for soil management in the U.S. and the E.U.
Protect, strengthen and expand conservation programs supported through the U.S. farm bill Support farmer advisory programs in the U.S. and the E.U.
Remove barriers and create incentives for GHG mitigation under the WTO and UNFCCC
Support a formal or informal process to examine the trade and clime change interface in the WTO
Overarching Rec 3: Increase Transparency
33
Measuring and monitoring GHG emissions is fundamental for managing emissions effectively. A robust understanding of how much carbon can be sequestered, or how much GHG emissions can be reduced by different practices, is central to making informed decisions about the most appropriate mitigation strategies. Measuring and monitoring emissions is also required to enable governments to implement policies and incentive frameworks.
Goal Objectives Interventions
Increase traceability and monitoring of GHG emissions from agricultural systems
Measure GHG emissions from agricultural sources
Develop GHG monitoring frameworks in developing countries
Develop simple on-farm monitoring tools
Increase the traceability of GHG emissions along the supply chain
Support the development of robust emissions tracking systems across supply chains
Facilitate the assessment of the impact of investments on GHG emissions
Develop tools that allow investors to assess the GHG impact of their investments
4. SEQUESTERING CARBON
34
Overarching Rec 4: Sequestering Carbon in Agricultural Systems
35
Soils hold an enormous amount of carbon. As much as 1,500 Gt of soil organic carbon (C) is stored to a depth of one meter, versus roughly 270 Gt C stored in standing forest stocks globally. There are numerous land and crop management practices that can increase the soil organic carbon in agricultural soils. Goal Objectives Interventions
Increase carbon sequestration in agricultural systems
Make the case for silvopastoral systems in Brazil
Initiate and support research and dialogue to establish better practices Support awareness campaigns targeted at producers to communicate best practice
Increase below and above-ground carbon sequestration in agricultural systems in Sub-Saharan Africa (SSA)
Facilitate the development of methods and decision support tools for trade-off assessment Support scientific network to collect and analyze long-term data series of SSA soil carbon stocks and fluxes
Support the development of biochar
Test and scale-up biochar production and use in key markets (e.g. China, Brazil). Enhance credibility and knowledge on biochar by promoting standards in biochar production
Main conclusions
• The agricultural sector accounts for roughly a fifth of GHG emissions when one considers the full life cycle of production including agriculture’s role in deforestation.
• A constructive debate on agriculture and climate change is hampered by a false dichotomy between food security and mitigation. The majority of GHG emissions from agriculture are life style emissions
• A major part of emission reductions could be achieved by shifting consumption patterns while supply side and cross cutting measures also need to play an important role.
