The United Nations Framework Convention on Climate Change (UNFCCC) is an international environmental treaty negotiated at the Earth Summit in Rio de Janeiro (June 1992), entered into force on 21 March 1994.
During the Earth Summit in Rio de Janeiro, in 1992, countries joined an international treaty, the United Nations Framework Convention on Climate Change, to cooperatively consider what they could do to limit average global temperature increases and the resulting climate change, and to cope with whatever impacts were, by then, inevitable. Hence, this Framework Convention is a universal convention of principle, acknowledging the existence of anthropogenic (human-induced) climate change and giving industrialized countries the major part of responsibility for combating it.
The objective of UNFCCC is to “stabilize atmospheric concentrations of greenhouse gases at a level that will prevent dangerous interference with the climate system”. The UNFCCC Secretariat plays a key role in the organisation of the negotiations. It is located in Bonn, Germany.
