Cutting food waste and shifting diets could slash food-related emissions by over 50%, according to Cornell-led research for the EAT-Lancet Commission. The global report, released Oct. 3 and involving experts from 35+ countries, highlights how transforming food systems could also prevent 15 million premature deaths annually.
Cornell researchers ran climate models showing food systems push Earth beyond safe limits on five of nine key environmental boundaries. But solutions—like boosting crop yields and protecting traditional diets—could ease pressure across all nine.
The study warns that without combined changes in diet, agriculture, and waste, food systems will remain unsustainable. Backed by Cornell Atkinson and the Gates Foundation, the findings aim to guide policymakers and the public toward a healthier food future.
