IUCN is a democratic Union that brings together the world’s most influential organisations and top experts
in a combined effort to conserve nature and accelerate the transition to sustainable development.
IUCN Member organisations set the direction of the Union's work, and global conservation efforts more broadly, every four years at the IUCN World Conservation Congress.
Six IUCN Commissions made up of over ten thousands experts inform IUCN’s knowledge and help produce its work.
IUCN's strength and mandate come from its diverse and powerful membership;
more than 1,400 Member organisations which provide the vision and oversight for the Union and its work.
Every four years, IUCN convenes the IUCN World Conservation Congress where IUCN Members set the global conservation agenda by voting on recommendations and guide the Secretariat’s work by passing resolutions and the IUCN Programme.
The IUCN Council is the principal governing body of IUCN between sessions of the World Conservation Congress. IUCN Members elect Commission chairs and representatives from Member organisations to serve four-year terms on the Council.
Acknowledging that IUCN sets the international quality standards for nature conservation, it is only logical that one of the leading financing institutions for biodiversity protection deepens its ties with IUCN. – Roland Siller, KfW Management Committee
