Animal welfare impact assessment (AWIA) is an emerging tool that systematically evaluates the welfare consequences of policies, regulations, and commercial practices before they are implemented.
Animal welfare impact assessment represents a systemic approach to welfare improvement: instead of reacting to welfare problems after they are established, AWIA builds welfare consideration into decision-making from the outset. This is particularly valuable in policy contexts where decisions affect large numbers of animals and are difficult to reverse. The challenge is methodological: welfare is multidimensional and resists simple quantification, and the models used to aggregate welfare impacts involve normative assumptions. Despite these challenges, systematic welfare assessment is better than the alternative — informal, ad hoc consideration that is easily overridden by economic arguments.
