Welfare impact assessment provides a framework for quantifying the effects of policy and practice changes on animal welfare, enabling evidence-based prioritisation of interventions.
Welfare impact assessment is a systematic approach to estimating the welfare effects of different practices, policies, and interventions. By combining estimates of the number of animals affected, the duration of welfare states, and the severity of positive and negative experiences, assessments aim to enable comparison of different welfare interventions. This approach helps animal welfare charities, policy makers, and advocates prioritise the most impactful work. Key challenges include uncertainty about animal subjective experience, interspecies comparisons, and long-term versus acute welfare effects. Despite limitations, welfare impact assessment represents an important tool for evidence-based decision-making in animal welfare.
