International Union for Conservation of Nature

Mission: Conserving biodiversity is central to the mission of IUCN. We demonstrate how biodiversity is fundamental to addressing some of the world’s greatest challenges: tackling climate change, achieving sustainable energy, improving human well-being and building a green economy.

Description: IUCN is a membership organization made up of more than 1,000 organizations, as well as 10,000 individual scientists and experts structured in six Commissions. The priorities and work of IUCN are set by Member organizations every four years and subsequently coordinated by a professional secretariat with 1,100 staff in more than 60 countries.
