IUCN Red List and Scientific Authority
IUCN Red List Categories
The IUCN Red List provides the most comprehensive inventory of global conservation status using scientifically agreed criteria to classify species according to extinction risk.
Categories range from Least Concern to Critically Endangered and Extinct, helping governments, funders, and practitioners prioritize action.
Environmental Policy and Standard Setting
IUCN World Conservation Congress
Every four years, the World Conservation Congress gathers thousands of delegates to set global conservation priorities, approve motions, and strengthen policy frameworks.
International Standards and Guidelines
IUCN develops global standards for environmental impact assessment, protected area management, ecosystem restoration, and private sector practices.
Collaborative Projects and On-the-Ground Impact
IUCN implements field projects in forests, wetlands, marine areas, and drylands, working with communities to restore ecosystems and improve livelihoods.
By integrating scientific data with traditional knowledge, these initiatives demonstrate practical pathways to sustainable natural resource management.
Strengthening Conservation through Collaboration
- Use the IUCN Red List to guide species protection and policy decisions.
- Engage with IUCN commissions to contribute expert knowledge and shape global standards.
- Participate in the World Conservation Congress to align priorities and build partnerships.
