How Much Does Agriculture Contribute to U.S. Greenhouse Gas Emissions?

In a recent report published by the U.S. Environmental Protection Agency, it was revealed that agriculture accounted for 10.5% of U.S. greenhouse gas emissions in 2022, a slight decrease from 681.6 million metric tons (MMT) in 2021 to 663.6 MMT in 2022 [ad8408a7]. The report highlighted that nitrous oxide emissions were the largest contributor at 309.1 MMT, followed by methane emissions at 277.0 MMT, and on-farm carbon dioxide emissions at 47.9 MMT. Additionally, indirect emissions through electricity use were recorded at 29.7 MMT [ad8408a7].

This data aligns with the findings from the South China Morning Post, which emphasized the significant role of meat production in climate change, accounting for about a quarter of all greenhouse gas emissions from agriculture [86659952]. Britta Klein, an agricultural engineer, noted that reducing meat consumption could lead to substantial decreases in greenhouse gas emissions, with a flexitarian diet potentially reducing emissions by 27% [86659952].

The report from the U.S. EPA also indicated that while agriculture's emissions decreased, the industrial sector remained the largest contributor to total emissions at 29.5%, with overall U.S. emissions increasing by 0.2% from 2021 to 2022 [ad8408a7]. This highlights the ongoing challenge of addressing emissions across various sectors, including agriculture, which is often overlooked in broader climate discussions.

Furthermore, the emphasis on reducing food waste and incorporating more plant-based foods into diets, as discussed by nutritionist Melanie Kirk-Mechtel, supports the notion that individual dietary choices can significantly impact greenhouse gas emissions [86659952]. By making informed choices about food consumption, individuals can contribute to a healthier planet while also addressing the pressing issue of climate change [86659952][ad8408a7].
