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


Published on

Scientists have proposed that 1 Gigatonne of annual emissions reductions from agriculture by 2030 will be necessary to stay within the 2°C limit. Emissions reductions would would need to increase in the longer-term. The figure below shows estimated business-as-usual emissions from agriculture in the top line, and the maximum amount of emissions from agriculture in a 2°C world in the bottom line. The gap - 1 Gigagonne - is the aspirational mitigation target. Learn more:

  1. 1. To meet the mitigation target, agriculture needs urgent investment in: Further work is also needed on reducing emissions throughout the food system, including: sequestering soil carbon, increasing agroforestry and avoiding deforestation, decreasing food loss & waste and shifting dietary patterns.

However, known practices could deliver just 21-40% of the needed reduction, even if implemented fully at scale. Emissions reductions from agriculture are not on track to meet the 2°C warming limit. At the Paris climate conference, 119 countries committed to mitigation in agriculture, (but few set quantitative targets). Reducing emissions from the industrial, transport and energy sectors will not be enough: agriculture is necessary to achieve the 2°C target. Agriculture will need to limit its greenhouse gas emissions to only 6–8 gigatonnes of CO2 e by 2030 while also increasing production. *GtCO2 e yr-1 = gigatonne of carbon dioxide equivalent per year Calculations are for non-CO2 emissions. See article for range of scenarios. This requires reducing non-CO2 emissions of 1 gigatonne CO2 e per year by 2030 based on our current trajectory.
