IUCN World Conservation Congress


One Nature One Future

The International Union for Conservation of Nature (IUCN) and the French government held the most recent IUCN World Conservation Congress from 3 to 11 September 2021 in Marseille. 

The Marseille Manifesto captured key messages that are globally and currently relevant and which relate to the Congress proceedings, including any notable and important commitments and announcements that emerged from Congress events. The focus is on the post-Covid recovery, the biodiversity crisis and climate emergency. 

The IUCN World Conservation Congress is where the world comes together to set priorities and drive conservation and sustainable development action. IUCN’s 1,400+ government, civil society and indigenous peoples’ Member organisations vote on major issues, action which guides humanity’s relationship with our planet for the decades ahead. IUCN’s unique and inclusive membership gives the Congress a powerful mandate as it is not solely government or non-government, but both together.
