Reduce Methane Emissions From Your Food Choices

Guide · June 2026

Methane is a greenhouse gas roughly 80 times more potent than CO₂ over 20 years — and a large share of it comes from how we produce food. The good news: food is one area where everyday choices add up fast.

Why methane matters

Methane is short-lived in the atmosphere but extremely potent while it lasts, so cutting it slows warming quickly. In the food system it comes mainly from livestock — especially cattle — from rice paddies, and from food waste rotting in landfill. That makes the plate a surprisingly powerful climate lever.

What moves the needle at the dinner table

Three habits do most of the work: shift toward more plant-rich meals, choose lower-impact proteins when you do eat animal products, and cut food waste so less ends up generating landfill methane. To see how much your diet contributes, estimate your food footprint.
