Annual emissions reductions from agriculture must reach 1 GtCO2e per year by 2030 to stay within 2°C warming limit

In the wake of the Paris Agreement, there is increased recognition of the need for mitigation in agriculture.

Current agricultural interventions will only deliver 21-40% of target, indicating need for transformative technical and policy options.

The Paris Agreement, signed in 2016 by 177 countries and counting, indicates a global commitment to limiting climate change to 2°C. In parallel to the Paris Agreement, countries submitted 162 climate change adaptation and mitigation plans to the United Nations. Three-quarters of plans included intentions to reduce emissions in the agriculture sector.

Translating national plans to global impacts on climate change is not possible without clear and measurable targets for emissions reductions. In response to this gap, the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), with 21 partners, put forward a preliminary target for agriculture, published in the journal Global Change Biology in May 2016.

Paris Climate Agreement Cannot Be Met Without Emissions Reduction Target for Agriculture

Researchers propose a 1 gigatonne carbon dioxide equivalent per year reduction target for farming by 2030 and find current interventions could only achieve 21-40% of this goal.

BURLINGTON, VERMONT (17th May 2016) – Scientists have calculated, for the first time, the extent to which agricultural emissions must reduce to meet the new climate agreement to limit warming to 2°C in 2100.

Scientists from the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), the University of Vermont, and partner institutions estimate that the agriculture sector must reduce non-CO2 emissions by 1 gigatonne CO2e per year in 2030. Yet in-depth analysis also revealed a major gap between the existing mitigation options for the agriculture sector and the reductions needed: current interventions would only deliver between 21-40% of mitigation required.
