Members and Observers
IPBES was established in 2012 by close to 140 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, this intention should be officially communicated to the IPBES secretariat from the relevant governmental authority. For example, this can take the form of a formal letter from the relevant Government Minister.
