The International Union for Conservation of Nature (IUCN) is a global membership union and leading authority on nature conservation and sustainable development. Founded in 1948, IUCN brings together governments, civil society organisations, scientists, and experts from over 160 countries to address the world’s most pressing environmental challenges.

The organisation works to conserve biodiversity, promote the sustainable use of natural resources, and support climate action through science-based solutions and policy influence. IUCN is widely known for its role in developing the IUCN Red List of Threatened Species, a critical tool for assessing the conservation status of species worldwide.

Through its programmes and partnerships, IUCN supports governments and communities in implementing conservation strategies, strengthening environmental governance, and advancing nature-based solutions. Its work spans ecosystems from forests and freshwater systems to oceans and coastal environments, contributing to global efforts to protect nature while supporting sustainable and inclusive development.
