The Contribution of Agriculture, Forestry and other Land Use activities to Global Warming, 1990–2012

Abstract We refine the information available through the IPCC AR 5 with regard to recent trends in global GHG emissions from agriculture, forestry and other land uses ( AFOLU ), including global emission updates to 2012. Using all three available AFOLU datasets employed for analysis in the IPCC AR 5, rather than just one as done in the IPCC AR 5 WGIII Summary for Policy Makers, our analyses point to a down‐revision of global AFOLU shares of total anthropogenic emissions, while providing important additional information on subsectoral trends. Our findings confirm that the share of AFOLU emissions to the anthropogenic total declined over time. They indicate a decadal average of 28.7 ± 1.5% in the 1990s and 23.6…
