Global assessments of supply- and demand-side climate mitigation in agriculture and livestock sectors

Abstract

 It has been reported that emission reductions in the agricultural and livestock sectors, which produce non-carbon dioxide emissions, will play an important role in achieving net-zero global greenhouse gas (GHG) emissions. In this study, we estimated the potential GHG emission reductions and costs associated with GHG reductions in the agricultural and livestock sectors worldwide, considering not only production-side measures but also consumption-side measures, such as limiting the consumption of livestock products. The results show that the global GHG emission reduction rate in the agriculture and livestock sector in 2050 is 50.2% in the scenario considering only the production side (compared to the scenario without measures), and 69.9% in the scenario considering both production and consumption sides (compared to the scenario with measures). This suggests that efforts on the consumption side of agriculture and livestock products will result in additional emission reductions of 20% (relative to the No Action Scenario) and play an important role in achieving net-zero emissions.
