Members and Observers
IPBES was established in 2012 by more than 100 governments, and its membership has continued to grow as IPBES' impact has increased.
Who can become a member?
All States Members of the United Nations are eligible for IPBES membership.
Why become a member?
To strengthen knowledge foundations for better policy through science, for the conservation and sustainable use of biodiversity, long-term human well-being and sustainable development.
How to become a member?
Should your Government wish to join IPBES, all that is required is for this intention to be officially communicated to the IPBES secretariat, by way of a formal letter, issued by or on behalf of the authority that would normally issue credentials for your national delegation to participate in a session of the IPBES Plenary, in other words by your Head of State or Government or minister for foreign affairs, consistent with your national policies and law.
