Animal Agriculture and Climate Change: Welfare and Environmental Co-Benefits

Industrial animal agriculture is a major driver of climate change. Understanding the co-benefits of dietary change for both animals and the environment strengthens the case for action.

Key Facts

Animal agriculture accounts for 14.5-18% of global greenhouse gas emissions according to the FAO
Livestock use 77% of global agricultural land but provide only 18% of global calories
Beef production uses 20 times more land and emits 20 times more greenhouse gases per gram of protein than legumes
A global shift toward plant-rich diets could free up land equivalent to the USA, China, EU, and Australia combined
Reducing meat and dairy consumption is one of the highest-impact individual climate actions
Climate change itself is creating welfare crises for billions of wild and farm animals globally

Welfare Considerations

The welfare and environmental cases for reducing animal product consumption are strongly complementary. Climate change is already causing welfare harms at scale - more frequent extreme weather events, drought, and flooding affect billions of wild and farmed animals. The land freed by dietary shift could be rewilded, providing habitat for wildlife. The greenhouse gas reductions from dietary change could prevent the worst climate scenarios that would otherwise create vast wild animal suffering through habitat destruction. Acting on animal welfare and climate simultaneously through dietary change is one of the most powerful individual-level interventions available.
