International livestock welfare standards are gradually converging around core principles, but significant gaps remain between high-standard and low-standard jurisdictions.
The international landscape of livestock welfare standards reflects deep inequalities in how different countries balance animal welfare against economic development and cultural traditions. High-standard jurisdictions have achieved meaningful improvements in farm animal welfare, but production often shifts to lower-standard countries when welfare requirements increase costs. This 'carbon leakage' for animal welfare is a fundamental challenge: improving standards in one jurisdiction may simply relocate suffering rather than reducing it globally. Effective global animal welfare improvement requires international standards with trade consequences, not just voluntary best practices.
