The Animal Welfare (Sentience) Act 2022 established the Animal Sentience Committee to advise UK government on how policy affects animals' ability to have positive and negative experiences, extending protection to previously excluded species.
The Animal Welfare (Sentience) Act represents a significant advance in the legal recognition of animal welfare in the UK, requiring government to consider impacts on animal sentience across all policy domains rather than just agriculture and environment. The extension of sentience recognition to crustaceans and cephalopods reflects the growing scientific evidence base reviewed by Birch et al. in 2021. The primary limitation is the advisory rather than binding nature of the Sentience Committee's recommendations. Strengthening the Committee's influence through binding recommendations or mandatory welfare impact assessments would increase the Act's effectiveness.
