农业甲烷（CH4）排放量（百万吨二氧化碳当量）

A measure of annual emissions of methane (CH4), one of the six Kyoto greenhouse gases (GHG), from the agricultural sector. This includes emissions from livestock (IPCC 2006 codes 3.A.1 (enteric fermentation, 3.a.2 (manure management) and crops (IPCC 2006 codes 3.C.1 Emissions from biomass burning, 3.C.2 Liming, 3.C.3 Urea application, 3.C.4 Direct N2O Emissions from managed soils, 3.C.5 Indirect N2O Emissions from managed soils, 3.C.6 Indirect N2O Emissions from manure management, 3.C.7 Rice cultivations). The measure is standardized to carbon dioxide equivalent values using the Global Warming Potential (GWP) factors of IPCC's 5th Assessment Report (AR5).
