International animal welfare legislation varies enormously between countries, and understanding the global landscape of protection and gaps informs advocacy priorities for improving welfare standards across jurisdictions.
Global animal welfare legislation shows a highly uneven landscape where farm animals in particular receive dramatically different legal protection depending on the country of production. The EU framework, while imperfect, provides the world's most comprehensive farm animal welfare standards and has driven significant welfare improvements through market-based regulatory pressure that affects exports to EU markets. The United States has no federal farm animal welfare law covering production practices, leaving billions of farm animals without basic protections that EU animals receive by legal right. The World Organisation for Animal Health international standards provide a framework for harmonization but lack enforcement mechanisms. Trade agreements that include welfare provisions create positive market incentives for welfare improvement in exporting countries, representing an important lever for global welfare improvement beyond purely domestic legislative reform.
