"When food is wasted, so are the natural and human resources that go into producing, processing, transporting, preparing and storing it. Those processes generate significant carbon dioxide emissions, which is a major driver of climate change."
A 2021 EPA report estimates that U.S. food loss and waste produces the equivalent of the annual carbon dioxide emissions of 42 coal-fired power plants, and enough water and energy to supply more than 50 million homes. And that's not including the impact of food that rots in landfills, producing methane, an even more potent greenhouse gas.
