Agriculture accounted for 10 percent of U.S. greenhouse gas emissions in 2014
Agriculture accounted for an estimated 10 percent of U.S. greenhouse gas (GHG) emissions in 2014. In agriculture, crop and livestock activities are important sources of nitrous oxide and methane emissions, notably from fertilizer application, enteric fermentation (a normal digestive process in animals that produces methane), and manure storage and management. GHG emissions from agriculture have increased by approximately 10 percent since 1990. During this time period, total U.S. GHG emissions increased approximately 7 percent.
