Welfare metrics that track aggregate animal suffering and wellbeing across species and production systems are essential for assessing whether advocacy efforts are creating real change.
Welfare metrics are the foundation of accountable animal advocacy. Without measures of aggregate welfare change — tracking whether more or fewer animals are experiencing better or worse lives over time — advocacy becomes aspirational rather than evidence-based. The development of standardized, population-level welfare metrics for major species groups would enable the same kind of progress tracking that conservation uses for endangered species or public health uses for disease burden. Strategic investment in welfare metrics infrastructure is as impactful as direct welfare advocacy because it creates the feedback loops that allow all advocacy to learn and improve.
