The ASEAN Centre for Biodiversity (ACB) is an intergovernmental regional centre of excellence that facilitates co-operation and co-ordination among the members of ASEAN, and with relevant national governments, regional and international organisations on the Conservation and Sustainable use of biological diversity. It is acknowledged as the first regional initiative to save the ASEAN's rich but highly threatened biodiversity and is a continuation of the ASEAN Regional Centre for Biodiversity Conservation (ARCBC), which was a joint co-operation project of the ASEAN and European Union (EU), and hosted by the Department of Environment and Natural Resources of the Philippines.
