How food companies commit to, audit, and (sometimes) deliver on animal welfare — and how advocates hold them accountable
The world's largest food companies — McDonald's, Walmart, Nestlé, Tyson, JBS, Costco — collectively purchase products from billions of farmed animals each year. Their purchasing decisions, welfare requirements, and supplier standards have more impact on farmed animal welfare than almost any other single factor.
Corporate animal welfare campaigns have become one of the most effective strategies for improving farmed animal welfare at scale. By targeting large buyers rather than individual farmers, advocates can leverage market concentration to drive systemic change across entire supply chains.
The cage-free transition has been the largest voluntary animal welfare improvement in history by number of animals affected. US cage-free egg production grew from ~5% in 2015 to ~40% by 2024, driven almost entirely by these corporate commitments rather than legislation.
Key lessons from the cage-free campaign:
The BBFAW provides the most comprehensive independent assessment of how food companies manage farm animal welfare across their supply chains. It ranks companies on management commitment, governance, policy implementation, and transparency.
Companies like Marks & Spencer, Waitrose, and Unilever consistently score in top tiers, with comprehensive welfare policies, strong governance, third-party auditing, and detailed public reporting. These companies treat animal welfare as a material business risk and opportunity.
Major companies like McDonald's, Walmart, Nestlé have made significant commitments (especially cage-free) but have inconsistent implementation, limited supply chain visibility, and often report welfare process rather than welfare outcomes. Progress is real but incomplete.
Many large meat processors and commodity-focused companies have minimal public welfare commitments and little supply chain visibility. JBS, the world's largest meat company, has faced significant criticism for its welfare governance. These companies represent priority targets for advocacy.
Shareholder Advocacy: Institutional investors increasingly file shareholder resolutions requiring animal welfare reporting and risk disclosure. The Farm Animal Investment Risk and Return (FAIRR) initiative engages investors on livestock sector risks including welfare.
Public Reporting and Rankings: Annual rankings like BBFAW, the Meat Hook, and Food and Agriculture Benchmark create reputational incentives for progress. Being publicly ranked as lagging is commercially damaging for consumer-facing companies.
NGO Campaigns: The Humane League's Open Wing Alliance, World Animal Protection, and others run targeted campaigns using combinations of consumer pressure, media coverage, and direct company engagement to secure and then enforce commitments.
Employee Advocacy: Sustainability-minded employees within food companies increasingly advocate for stronger welfare policies internally — often more effectively than external pressure alone.
Supply Chain Transparency Requirements: Growing legal requirements in France, UK, and Germany requiring companies to conduct human rights and environmental due diligence are beginning to extend to animal welfare, creating new legal obligations for supply chain oversight.
Corporate campaigns are among the most effective levers for large-scale animal welfare improvement. Learn how to engage.
