Global share of methane emissions 2023, by sector

Agriculture-related activities and processes, such enteric fermentation, were responsible for roughly 46 percent of global human-made methane emissions in 2023. Agriculture, together with fuel exploitation and the waste sector, accounted for around 97 percent of global methane emissions in 2023. Methane is an organic gas formed by carbon and four hydrogen atoms. It is one of the most potent greenhouse gases in the short term due to its high warming potential. It can be produced either by natural or anthropogenic (from human activities) processes.

农业相关活动与过程，诸如肠道发酵等，在2023年全球人为甲烷排放中占据了约46%。农业、燃料开采及废弃物处理领域共同构成了2023年全球甲烷排放的97%左右。甲烷是由一个碳原子和四个氢原子组成的有机气体。鉴于其显著的增温潜力，它是短期内最具效力的温室气体之一。甲烷可通过自然过程或人为活动（人类活动）产生。
