Burger King: Cow diet to aid climate

Burger King is staging an intervention with its cows.

The chain has rebalanced the diet of some of the cows by adding lemon grass in a bid to limit bovine contributions to climate change. By tweaking their diet, Burger King said Tuesday that it believes it can reduce a cow’s daily methane emissions by about 33%.

Cows emit methane as a by-product of their digestion, and that has become a potential public relations hurdle for major burger chains.

Greenhouse gas emissions from the agriculture sector made up 9.9% of total U.S. greenhouse gas emissions in 2018, according to the Environmental Protection Agency.
