Policy and Welfare

Animal Welfare: A Complete Evidence Summary

A synthesis of the key evidence-based principles that underpin modern animal welfare science and their implications for how we treat animals.

Key Facts

All vertebrates and many invertebrates have the neurological capacity for pain and suffering
The Five Domains model integrates physical and psychological welfare into a comprehensive framework
Evidence shows that welfare and productivity align across most farmed species when systems are well managed
Consumer choices, corporate policy, and legislation are the three most powerful levers for welfare change

Welfare Considerations

Animal welfare science has established that animals suffer, that we can measure and improve their welfare, and that doing so is both ethically right and practically achievable. The remaining challenge is implementation at scale — translating evidence into policy, market behavior, and individual action. Every person who engages with welfare evidence and acts on it contributes to this translation.
