The United Nations Commission on Sustainable Development comes to NY this spring to discuss Energy and Sustainability. From 16 -27 April the UN Commission on Sustainable Development (CSD) convenes in New York. One of the issues on the agenda for its ninth session (hence CSD 9) will be energy and sustainability. The CSD was established to monitor the implementation of the outcome of the Rio Earth Summit (1992). Countries report to the Commission on the progress made, and the Commission advises the UN and its Member States on how to achieve sustainable development in the 21st century.
