Parties adopted the Cancun Adaptation Framework (CAF) as part of the Cancun Agreements at the 2010 Climate Change Conference in Cancun, Mexico (COP 16/ CMP 6). In the Agreements, Parties affirmed that adaptation must be addressed with the same level of priority as mitigation.

The CAF is the result of three years of negotiations on adaptation under the AWG-LCA that had followed the adoption of the  Bali Action Plan at the 2007 Climate Change Conference in Bali, Indonesia (COP 13/ CMP 3).
