Established in 2005, the ACB is an intergovernmental regional centre of excellence that facilitates cooperation and coordination among the members of ASEAN, and with relevant national governments, regional and international organizations on the Conservation and Sustainable use of biological diversity, guided by fair and equitable sharing of benefits arising from the use of such biodiversity. ACB is a continuation of the ASEAN Regional Centre for Biodiversity Conservation (ARCBC), which was established from 1999-2004 as a joint cooperation project of the ASEAN and European Union (EU), and hosted by the Department of Environment and Natural Resources of the Philippines. It builds on the bridge that fostered strong collaboration among ASEAN Member States (AMS) and between ASEAN and EU partner institutions, and gained recognition in the regional and global arena for biodiversity. ACB was established to carry on the work of the completed ARCBC project. Regional climate change and biodiversity conservation is listed as one of its Thematic Areas of Cooperation.
