Livestock methane emissions in the United States

Sadie S

This review reports on a study, Miller et al. (2013), that used the US Department of Agriculture – National Agricultural Statistics Service (USDA-NASS) livestock inventory estimates for 2013 and methane emission rates per unit of feed dry matter intake from two large datasets to estimate total methane emission from enteric fermentation for the United States. The estimates are reported in this paper and are compared to and verified by US EPA and other studies.
