IUCN is a membership Union composed of both government and civil society organisations. It harnesses the experience, resources and reach of its more than 1,400 Member organisations and the input of more than 18,000 experts. This diversity and vast expertise makes IUCN the global authority on the status of the natural world and the measures needed to safeguard it.
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.
