The International Union for Conservation of Nature (IUCN) is the world’s oldest and largest global environmental organization, with a mission to influence, encourage, and assist societies to conserve nature and ensure that natural resources are used equitably and sustainably. Globally recognized for its scientific authority and leadership in biodiversity conservation, IUCN is best known for its Red List of Threatened Species and its critical role in shaping global environmental policy.

The organization fosters a diverse and inclusive work culture grounded in collaboration, respect, and innovation, offering its employees meaningful career opportunities, cross-cultural experiences, and flexible work arrangements across its global offices. Founded in 1948, IUCN has evolved into a unique hybrid organization that bridges governments, NGOs, scientists, and indigenous groups, leveraging evidence-based knowledge and partnerships to drive conservation impact.

With a membership of over 1,400 organizations and thousands of experts spanning more than 160 countries, IUCN operates a global network with regional and country programs focused on climate change, ecosystems, species, and governance. Its core values include integrity, transparency, inclusiveness, and sustainability, and its commitment to corporate social responsibility is embedded in its work to safeguard biodiversity, support livelihoods, and promote environmental justice.
