Animal advocacy organisations vary enormously in their approaches and impact. Research from Effective Altruism-aligned organisations is building an evidence base for which strategies deliver the most welfare improvement per pound spent.
Welfare advocacy resources are finite, making strategic allocation critical to maximising impact. Evidence suggests that corporate outreach campaigns targeting food industry commitments have among the highest verified impact per dollar spent, affecting large numbers of animals through policy changes at scale. Individual outreach through leafleting and online advertising has demonstrated effects but at lower scale per unit cost. Understanding this evidence allows advocates to direct their own time and donations toward approaches most likely to reduce animal suffering.
