The UN Charter does not specifically mention the environment or sustainable development. However, there has been increased activity in the area over the years.
Both the General Assembly and the Economic and Social Council consider environmental questions. The UN Environmental Programme (UNEP) is the lead programme in this area and the Commission on Sustainable Development is a key forum for UN Member States to discuss questions related to the environment.
In 2014, the United Nations Environment Assembly (UNEA), the successor of the UNEP Governing Council, began to meet.
