Commission on Sustainable Development
The United Nations Commission on Sustainable Development (CSD) was a body under the UN Economic and Social Council (ECOSOC) tasked with overseeing the outcomes of the 1992 United Nations Conference on Environment and Development/Earth Summit. It was replaced in 2013 by the High-level Political Forum on Sustainable Development, which meets both under the General Assembly every four years and the ECOSOC in other years.
