ScienceFood Waste Major Contributor to Climate Change, UNEP Reports
Food waste produces five times more greenhouse gas emissions than aviation and releases methane responsible for 10% of global greenhouse gases, says the UN Environment Programme. The 2024 Food Waste Index Report states that 1.05 billion tonnes of food, or one-fifth of consumer-available food, is wasted annually, with 60% from households. This waste generates methane in landfills, contributing to a third of global warming.
