Welfare Economics of Veganism at Scale

Estimating the welfare impact of veganism requires engaging with the economics of how individual dietary choices translate into reduced animal farming at population scale — a question with significant implications for advocacy strategy.

Key Facts

Each vegan reduces consumption of approximately 100 animal products per year on average, though most of these are eggs and dairy
The elasticity of meat supply to demand means each unit of reduced demand translates to roughly 0.5-0.8 fewer animals farmed
Veganism disproportionately reduces consumption of high-welfare-impact species: broiler chickens (worst welfare per kg) and eggs
Corporate and institutional dietary shifts have larger leverage per unit of advocacy effort than individual consumer conversion
Plant-based and cultivated proteins offer a path to near-zero farmed animal suffering at scale, surpassing incremental welfare reform

Welfare Considerations

From a welfare economics perspective, veganism is among the highest-impact individual actions available, primarily through reducing broiler chicken and egg consumption. However, the most effective deployment of advocacy resources depends on context: individual conversion, corporate campaigns, policy advocacy, and technology investment each have different impact-per-effort ratios. Evidence-based effective animal advocates often combine personal veganism with high-leverage institutional work.

What You Can Do

Adopt a predominantly plant-based diet, prioritising reduction of chicken and eggs for highest welfare impact per meal
Support corporate campaigns targeting institutional food procurement rather than only individual consumer conversion
Engage with effective animal advocacy frameworks to maximise the welfare impact of your time and resources
Donate to organisations with demonstrated track records of corporate welfare commitments rather than primarily awareness campaigns
