The compilation and production of The IUCN Red List of Threatened Species™ would not be possible without the financial support of many donors.


IUCN would like to thank all current and past donors who have generously provided funds to support this work, and in particular would like to acknowledge the partnership with Toyota Motor Corporation (Toyota). This long term partnership, which is part of the Toyota Environmental Challenge 2050, will support the assessment of more than 28,000 species to achieve IUCN’s goal of doubling the number of species assessed by 2020 to make The IUCN Red List a more complete ‘Barometer of Life’ - providing a stronger base for effective conservation action. The partnership with Toyota has also contributed significantly to the development of the new IUCN Red List web platform enabling these critically important data to be more easily accessible to all users. The development of the new IUCN Red List web platform has also been generously supported by Synchronicity Earth.

IUCN would also like to acknowledge the ongoing support from The Rufford Foundation; the IUCN Red List Partners; the Critical Ecosystem Partnership Fund (CEPF); the European Commission; the French Ministry for Foreign Affairs (DgCiD – Direction générale de la Coopération internationale et du Développement); the Integrated Biodiversity Assessment Tool (IBAT); the Environment Agency – Abu Dhabi (EAD); JRS Biodiversity Foundation; and the Franklinia Foundation.

In addition, IUCN is very grateful for past support for The IUCN Red List provided by the MAVA Foundation for Nature Conservation (MAVA Stiftung für Naturschutz / Fondation pour la Protection de la Nature); the Gordon and Betty Moore Foundation; the MacArthur Foundation; the Esmée Fairburn Foundation; and the EDF Corporate Foundation (Fondation EDF).
