The UN Framework Convention on Climate Change (UNFCCC) created an international environmental treaty to combat "dangerous human interference with the climate system" partially through stabilising greenhouse gases in the atmosphere.
One hundred fifty-four nations signed the treaty in 1992 during UNCED, informally known as the Earth Summit, and entered into force in 1994. The Kyoto Protocol was the first implementation of measures under the UNFCCC. This protocol was substituted by the Paris Agreement, which came into force in 2016.
