These Face Masks for Cows Have Nothing to Do With Coronavirus

Agriculture is second only to energy in its contribution to global greenhouse-gas emissions, and raising animals—especially cattle—drives almost half the industry’s footprint. That hasn’t been good news for beef and dairy producers, who are being abandoned by climate-conscious investors and consumer alike. Francisco Norris, however, sees it as an opportunity.

Norris is a co-founder of Zelp Ltd., short for Zero Emissions Livestock Project, a U.K.-based startup developing a wearable device for cows that may be able to reduce their methane emissions by up to 60%. “We need to do everything we can to reduce the problem,” Norris says. “We understand that the best position for us to help address this issue is here, producing this kind of technology.”
