The United Nations Environment Programme's World Conservation Monitoring Centre or UNEP-WCMC is an executive agency of the United Nations Environment Programme, based in Cambridge in the United Kingdom. UNEP-WCMC has been part of UNEP since 2000, and has responsibility for biodiversity assessment and support to policy development and implementation. The World Conservation Monitoring Centre was previously an independent organization jointly managed by IUCN, UNEP and WWF established in 1988, and prior to that the Centre was a part of the IUCN Secretariat.
UNEP-WCMC has a mandate to facilitate the delivery of the global indicators under the CBD's 2010 biodiversity target on the rate of loss of biological diversity. It also manages the World Database of Protected Areas in collaboration with the IUCN World Commission on Protected Areas. A series of world atlases on biodiversity topics have been published by UNEP-WCMC through University of California Press.
