Methane is a greenhouse gas produced largely from bacteria that live in soil, water and the stomachs of ruminant animals (mammals that have a stomach with four compartments that ferment food as a major part of the digestion process). Methane is produced on dairy farms mainly through enteric fermentation and manure storage, and accounts for 11% of greenhouse gas emissions each year in the U.S.

This fact sheet provides an overview of methane emissions from dairy production along with mitigation techniques (5 pages; 2016).
