According to the Environmental Protection Agency (EPA), beef farmers have reduced their greenhouse gas emissions per cow by 24% since 1990.
This number is significant, as beef production is one of the largest sources of greenhouse gas emissions in the US, due in part to the large amounts of feed and energy required to raise and process the meat. The reduction in emissions per cow is the result of improved feed management, increased use of renewable energy sources, and more efficient animal breeding practices, among other things.
