Zoo welfare standards vary enormously globally. Accreditation schemes help identify institutions that meet higher welfare standards, but the baseline for legal operation remains low in many countries.
Zoo animal welfare exists on a wide spectrum. Accredited zoos with conservation missions, naturalistic habitats, and robust welfare monitoring achieve substantially better outcomes than unaccredited facilities. However, even high-quality zoos involve inherent welfare compromises for large-ranging species. Consumers of zoo experiences can drive improvement by choosing accredited facilities, avoiding attractions with welfare concerns, and supporting stronger national zoo licensing standards.
