The Conference of the Parties (COP) is the supreme decision-making body of the United Nations Framework Convention on Climate Change (UNFCCC).

At this 25th edition organized and presided by Chile, to be held December 2-13 in Madrid, Spain, the 197 Parties that make up the treaty - 196 nations plus the European Union - will seek to move towards the implementation of the agreements that have been reached under the Convention that lays down specific obligations for all Parties to fight climate change.

The first COP was held in Berlin in 1995. To date, 24 COPs have taken place, the last one in Katowice, Poland, in December 2018.

The COP25 Presidency, which will be led by Minister Carolina Schmidt, starts in December 2019 and ends in December 2020.
