Climate policies can unintentionally increase hunger by raising food prices and limiting calorie supply. However, they also reduce air pollution, lowering ground-level ozone that harms crops.
Cleaner air improves yields of staples like wheat, rice, and maize, partly offsetting these negative effects. By 2050, climate action could put 61 million more people at risk of hunger, but ozone reductions may reduce this by 8.4 million (about 15%).
Benefits are greatest in vulnerable regions such as India and sub-Saharan Africa. Overall, cleaner air helps but does not fully offset the risks, highlighting the need for additional measures like improving agriculture and reducing food waste.
