Low-methane meat is a thing now. Earlier this week, fast-food chain Burger King unveiled a climate-friendly burger it plans to offer in some U.S. locations. The limited-supply meat comes from cows that are fed lemongrass to reduce the atmospheric impact of their methane-laden belches. It’s an early move in what may become a race to put low-carbon labels on meat. If emissions from electricity production and transportation eventually come under control, the environmental impact of agriculture—which represents more than nine per cent of U.S. emissions directly—may become the next front in the fight to slow global warming.
