Created in 1948, IUCN is now the world’s largest and most diverse environmental network, harnessing the knowledge, resources and reach of our more than 1,400 Member organisations and 15,000 experts. This diversity and expertise makes IUCN the global authority on the status of the natural world and the measures needed to safeguard it.
IUCN is a membership union that brings government and civil society organisations together with a global network of experts.
IUCN is active around the world, from research and analysis to impactful projects and informing policy.
IUCN has produced authoritative reports, standards, guidelines and tools for over seven decades.
Our broad membership also means we can incubate ideas and are a trusted repository of best practices, tools and international standards. We provide a neutral space in which governments, NGOs, scientists, businesses, local communities, indigenous peoples’ organisations and others can work together to solve environmental challenges and achieve sustainable development.
Working with many partners and supporters, IUCN implements a large and diverse portfolio of conservation projects worldwide. These projects combine the latest science with traditional knowledge of local communities to work to reverse habitat loss, restore ecosystems and improve people’s well-being.
IUCN's Members, expert Commissions and Secretariat work together 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.
IUCN Commissions include thousands of experts from around the world who inform IUCN’s knowledge and help produce its work.
Secretariat and Director General
In addition to contributing knowledge, convening and capacity-building work, the Secretariat manages projects worldwide and coordinates support services to Members and Commissions.
