Nature 2030

A Union in action

Nature 2030: IUCN Programme 2021-2024 marks the culmination of many years of deliberation across the Union. Adopted by democratic vote at the IUCN World Conservation Congress in Marseille, the Nature 2030 IUCN Programme, for the first time, sets its ambition over ten years. It is a call for mobilisation to our Members, Commissions and Secretariat. This longer-term outlook aligns with the United Nations 2030 Agenda for Sustainable Development and the post-2020 global biodiversity framework.
