The United Nations Commission on Sustainable Development (CSD) was established by the UN General Assembly in December 1992 to ensure effective follow-up of United Nations Conference on Environment and Development (UNCED), also known as the Earth Summit.

The Nineteenth session of the UN Commission on Sustainable Development (CSD 19) convened from 2-14 May 2011, at UN Headquarters in New York. The CSD meets annually, in two-year cycles, with each cycle focusing on clusters of specific thematic and cross-sectoral issues. The five thematic areas for CSD 19 were Transport, Chemicals, Waste Management, Mining and The 10 Year Framework of Sustainable Consumption and Production (10YFP).
