Climate change threatens animal welfare on a global scale, and climate policy should explicitly integrate animal welfare considerations alongside emissions and biodiversity goals.
Climate and animal welfare policy have historically been developed in silos, missing important synergies and trade-offs. The most welfare-positive climate strategies - reducing farmed animal numbers through dietary transition - also have the greatest emissions benefits. Climate adaptation strategies for agriculture that maintain intensive farming for emissions efficiency may come at high welfare costs. Integrating welfare expertise into climate policy development is essential to identify co-beneficial solutions.
