According to the EPA, the top three sources of anthropogenic methane in the United States are the combined energy sector, 40 percent of the total; livestock, 36 percent; and landfills, 18 percent. Methane emissions from livestock operations are the result of microbial fermentation and methanogenesis in the forestomach of ruminants such as these dairy cattle and similar fermentation processes in manure.
