Breakdown of GHG emissions from agriculture in Brazil 2021, by segment

Enteric fermentation was by far the largest source of greenhouse gas emissions in Brazil's agriculture sector in 2021, accounting for almost 70 percent of total emissions (excluding energy-related emissions). Enteric fermentation is a part of the digestive process in ruminant animals and produces large amounts of methane, a potent greenhouse gas. Some of the biggest carbon-polluting meat and dairy companies are based in Brazil, such as JBS and Marfrig.

2021年，在巴西的农业领域中，肠道发酵无疑是温室气体排放的最大来源，占总排放量（不含能源相关排放）的近70%。肠道发酵是反刍动物消化过程的一部分，产生了大量的甲烷，一种强效的温室气体。巴西一些最大的碳污染肉类和乳制品公司，如JBS和Marfrig，均设于此。
