The 2019 United Nations Climate Change Conference, also known as COP25, was the 25th United Nations Climate Change conference. It was held in Madrid, Spain, from 2 to 13 December 2019 under the presidency of the Chilean government. The conference incorporated the 25th Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC), the 15th meeting of the parties to the Kyoto Protocol (CMP15), and the second meeting of the parties to the Paris Agreement (CMA2).
The conference was planned to be held in Brazil in November 2019, but a year before the planned start, newly elected President Jair Bolsonaro withdrew the offer to host the event, citing economic reasons. Then Chile stepped up and became the new host, but massive protests against social inequality in the lead-up to the meeting forced it late October 2019 to withdraw from hosting. Then by mutual agreement between the UN, Chile, and Spain, the latter became the new host.
Various climate activists had set out from Europe to South America by sailboat, before the decision had been taken to relocate COP25 to Madrid. In mid-November, some of these activists joined an alternative conference, the "Forest COP", near the centre of the Amazon jungle, in Terra do Meio. The event was attended by indigenous leaders, scientists and academics such as Eduardo Góes Neves, and activists such as Nadezhda Tolokonnikova. After the Forest COP, a follow-on event, "Amazônia Centro do Mundo" (Amazon: The Centre of the World) took place on 17 November in nearby Altamira.
