Enhancing Climate Change Mitigation through Agriculture

image of Enhancing Climate Change Mitigation through Agriculture

Agriculture, with its growing contribution to global greenhouse gas emissions and opportunities to mitigate emissions, can help close the gap between existing global mitigation efforts and those that are needed to keep global warming to between 1.5 °C and 2 °C by the end of the century. Global scale and farm scale analyses are used to evaluate both the effectiveness of different policy options to reduce agricultural emissions, and the impact on competitiveness, farm income, food security, and government finances. In order to contribute to global mitigation efforts, countries will need to design agricultural policy measures that can navigate these trade-offs within the context of their national policy priorities and objectives. As most countries have not yet implemented policies to reduce emissions from agriculture, the analyses provided here come at an opportune time to inform this policy development.

Executive Summary

Agriculture is one of the main sectors responsible for climate change. Between 2007 and 2016, the sector directly contributed approximately 12% of global anthropogenic greenhouse gas (GHG) emissions (6.2 ± 1.4 GtCO2eq), and was responsible for an additional 9% of global GHG emissions each year (4.9 ± 2.5 GtCO2eq) from changes in land use, i.e. the conversion of forestland to cropland and grassland.
