United Nations Framework Convention on Climate Change
The United Nations Framework Convention on Climate Change (UNFCCC) was adopted in May 1992 and signed at the Rio de Janeiro Earth Summit. The Convention established general principles to stabilise greenhouse gas concentrations and prevent dangerous human-caused interference with the climate system. The Convention includes requirements such as preparing national inventories of GHG emissions and a commitment to reduce emissions to 1990 levels. The Convention has nearly universal membership, with more than 190 signatory countries.
