The World Bank, through its International Bank for Reconstruction and Development (IBRD), has issued a five-year, $150-million Wildlife Conservation Bond (WCB) sustainable development bond in support of South Africa’s efforts to conserve endangered species. Also known as the “Rhino Bond,” it includes a potential performance payment from the Global Environment Facility (GEF), which will contribute to protecting and increasing black rhino populations in two protected areas in the Eastern Cape.
