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.
Of that amount, methane emissions from livestock (called enteric fermentation) comprised more than a quarter of the emissions from the agriculture sector. With an over-the-top social media campaign that teeters between vulgarity and science (sprinkled with more vulgarity), Burger King is banking on the heightened awareness of climate change and its responsibility to limit its own role.
According to a recent poll by The Associated Press-NORC Center for Public Affairs Research, about two out of three Americans say corporations have a responsibility to combat climate change. The gravitational pull of climate change is increasingly finding its way onto national political stage.
Potential customers are also cutting down on the amount of meat they consume, citing both environmental and dietary concerns. Burger King and rival McDonald’s have added meat alternatives to their menus.
