The United Nations Conference on Environment and Development (UNCED), also known as the Rio de Janeiro Conference or the Earth Summit (Portuguese: ECO92, Cúpula da Terra), was a major United Nations conference held in Rio de Janeiro from 3 to 14 June 1992. The Rio conference was attended by 108 heads of state and government, and helped establish and disseminate the concept of sustainable development. A key achievement of the 1992 conference was the establishment of the United Nations Framework Convention on Climate Change (UNFCCC) established in part as an international environmental treaty to combat "dangerous human interference with the climate system" and to stabilize greenhouse gas concentrations in the atmosphere. It was signed by 154 states at the United Nations Conference on Environment and Development (UNCED). By 2022, the UNFCCC had 198 parties.
