EnvironmentStrong evidence
Reducing meat and dairy consumption, especially beef and lamb, is one of the largest ways an individual's diet can reduce greenhouse gas emissions.
Yes. Animal foods produce most of food's emissions, and beef and lamb produce the most per gram of protein. Eating less of them lowers a diet's footprint substantially.
