One billion tonnes of wasted food
The world wasted 1.05 billion tonnes of food in 2022 — about a fifth of all food available to consumers — while hundreds of millions went hungry.
How this affects people
Most food waste happens in households, followed by food service and retail.
Food loss and waste generate 8–10% of global greenhouse-gas emissions — almost five times aviation's.
