The International Union for Conservation of Nature (IUCN) is a membership Union uniquely composed of both government and civil society organisations. It provides public, private and non-governmental organisations with the knowledge and tools that enable human progress, economic development and nature conservation to take place together.

Created in 1948, IUCN has evolved into the world’s largest and most diverse environmental network. It harnesses the experience, resources and reach of its 1,300 Member organisations and the input of some 16,000 experts. IUCN is the global authority on the status of the natural world and the measures needed to safeguard it. Our experts are organised into six commissions dedicated to species survival, environmental law, protected areas, social and economic policy, ecosystem management, and education and communication.

The ability to convene diverse stakeholders and provide the latest science, objective recommendations and on-the-ground expertise drives IUCN’s mission of informing and empowering conservation efforts worldwide. We provide a neutral forum in which governments, NGOs, scientists, businesses, local communities, indigenous peoples groups, faith-based organisations and others can work together to forge and implement solutions to environmental challenges.

By facilitating these solutions, IUCN provides governments and institutions at all levels with the impetus to achieve universal goals, including on biodiversity, climate change and sustainable development, which IUCN was instrumental in defining.

Combined, our knowledge base and diverse membership make IUCN an incubator and trusted repository of best practices, conservation tools, and international guidelines and standards. As the only environmental organisation with official United Nations Observer Status, IUCN ensures that nature conservation has a voice at the highest level of international governance.

IUCN’s expertise and extensive network provide a solid foundation for a large and diverse portfolio of conservation projects around the world. Combining the latest science with the traditional knowledge of local communities, these projects work to reverse habitat loss, restore ecosystems and improve people’s well-being. They also produce a wealth of data and information which feeds into IUCN’s analytical capacity.

Through their affiliation with IUCN, Member organisations are part of a democratic process, voting Resolutions which drive the global conservation agenda. They meet every four years at the IUCN World Conservation Congress to set priorities and agree on the Union’s work programme. IUCN congresses have produced several key international environmental agreements including the Convention on Biological Diversity (CBD), the Convention on International Trade in Endangered Species (CITES), the World Heritage Convention, and the Ramsar Convention on wetlands. We continue to help these conventions strengthen and evolve so that they can respond to emerging challenges.

Our Member organisations are represented by the IUCN Council – the governing body. Headquartered in Switzerland, IUCN Secretariat comprises around 950 staff in more than 50 countries.
