The rotating Presidency of the 25th Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) (COP25) was due for Latin America. It was going to be held by Brazil, which declined to hold the summit after the election of President Jair Bolsonaro. After Brazil resigned, the Government of Chile offered its capital, Santiago de Chile, as headquarters. After the UNFCCC accepted Chile's offer, it appointed Carolina Schmidt, Chile's Minister of Environment, as president of COP25.
On Friday, November 1, 2019, the UNFCCC COP Bureau accepted the proposal by the Government of Chile to hold the 2019 COP in Madrid, following the offer of the Government of Spain. Therefore, the conference is being held under the Presidency of the Government of Chile and with the logistical support of the Government of Spain.
The Government of Spain is working closely with the Secretariat of the Climate Change Agreement and the Executive of Chile to organise the Conference and handle the logistics required for an event of this nature, and is coordinating with representatives of the Community and the City Council of Madrid. It is also prioritising the participation of all delegates as well as the presence and participation of civil society.
