The Endangered Wildlife Trust (EWT), a conservation NGO, recognised the need for a body to assist business in the integration or mainstreaming of biodiversity into its strategies and activities. This led the EWT to establish the National Biodiversity and Business Network (NBBN) in 2013 in partnership with various business sectors. The aim of the NBBN is to facilitate a reduction in the impact of business on biodiversity in South Africa. We aim to achieve this through the Biodiversity Disclosure Project (BDP). The BDP is a voluntary biodiversity disclosure mechanism that initially targets South African companies. The BDP will enable businesses to disclose their biodiversity performance in a standardised and comparable manner. The project also supports the private sector in mainstreaming biodiversity into their strategies and activities, thereby helping business recognise, measure, value, and responsively manage their direct and indirect dependencies and impacts on biodiversity.
