The United Nations Framework Convention on Climate Change (UNFCCC or FCCC) is an international environmental treaty negotiated at the United Nations Conference on Environment and Development (UNCED), informally known as the Earth Summit, held in Rio de Janeiro from 3 to 14 June 1992.
The objective of the treaty is to "stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system."
The treaty itself set no binding limits on greenhouse gas emissions for individual countries and contains no enforcement mechanisms.
In that sense, the treaty is considered legally non-binding.
Instead, the treaty provides a framework for negotiating specific international treaties (called "protocols") that may set binding limits on greenhouse gases.
The UNFCCC was opened for signature on 9 May 1992, after an Intergovernmental Negotiating Committee produced the text of the Framework Convention as a report following its meeting in New York from 30 April to 9 May 1992.
It entered into force on 21 March 1994.
As of May 2011, UNFCCC has 195 parties.
The parties to the convention have met annually from 1995 in Conferences of the Parties (COP) to assess progress in dealing with climate change.
In 1997, the Kyoto Protocol was concluded and established legally binding obligations for developed countries to reduce their greenhouse gas emissions.
The 2010 Cancún agreements state that future global warming should be limited to below 2.0 °C (3.6 °F) relative to the pre-industrial level.
The 20th COP will take place in Peru in 2014.
