Zoo Welfare Accreditation and Standards

Zoo accreditation systems establish minimum and aspirational welfare standards that significantly affect millions of captive animals.

Key Facts

The Association of Zoos and Aquariums accredits approximately 240 institutions in North America
Accreditation requires meeting standards for animal care, space, veterinary services, and enrichment programs
Fewer than 10% of facilities exhibiting animals worldwide meet recognized accreditation standards
Accreditation processes have strengthened over time, increasingly incorporating animal welfare outcomes
GFAS accreditation for sanctuaries has higher welfare standards than many zoo accreditation programs

Welfare Considerations

Zoo accreditation creates a floor of standards that separates facilities genuinely committed to animal welfare from roadside attractions and pseudosanctuaries. While accredited institutions are not perfect, they typically provide substantially better care than unaccredited facilities. Advocacy for stronger standards, outcome-based welfare metrics, and transparent reporting continues to improve conditions for captive animals worldwide.

What You Can Do

Choose to visit only AZA, EAZA, or similarly accredited zoos and aquariums
Avoid roadside attractions, unaccredited "sanctuaries," and traveling wildlife exhibits
Support campaigns for stronger accreditation requirements including animal welfare outcomes
Report concerns about animal welfare at any exhibiting facility to accrediting bodies
Advocate for government oversight of minimum welfare standards for all exhibiting facilities
