Legal recognition of farm animal sentience underpins welfare legislation worldwide. Tracking global progress in sentience recognition helps identify where advocacy can accelerate welfare reform.
Legal sentience recognition matters because it shifts the framing of animal welfare from property protection to recognition of morally significant interests. Where sentience is legally recognised, governments face legal accountability for considering animal interests in policy decisions. This creates leverage for welfare advocates to challenge policies that cause unnecessary animal suffering. Expanding sentience recognition to invertebrates - as the UK has done for decapod crustaceans and cephalopods - extends protection to billions more animals. Supporting campaigns for sentience legislation in jurisdictions that lack it is high-leverage welfare advocacy.
