Effective altruism approaches to animal welfare giving aim to maximise welfare improvement per donation through evidence-based evaluation of intervention effectiveness.
Effective giving for animal welfare applies the same evidence-based logic used in global health philanthropy to animal welfare interventions. The enormous numbers of animals affected by food system practices means that highly cost-effective interventions exist in the welfare space. Corporate campaign funding and research supporting evidence-based welfare improvement can leverage much larger changes than direct service provision alone. However uncertainty is significant in welfare cost-effectiveness estimates, warranting diversification across different intervention types and species. Engagement with evidence and ongoing evaluation improves giving effectiveness over time.
