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.

[4][5][6] In November, Teresa Ribera, the Spanish Minister for the Ecological Transition, announced the conference would be held at the IFEMA facilities in Madrid.

The green zone was intended to be an open-dialogue pavilion for all types of civil actors, ranging from NGOs to businesses, academia and sponsors.

[9] The event was supported among others by Iberdrola, Endesa, Santander, Suez, Telefónica, Fundación Abertis, Banco Bilbao Vizcaya Argentaria, Acciona and Indra.

[10] Harjeet Singh, of environmental group ActionAid International, said that moving the summit from Chile to Spain with only four weeks' notice presented "real barriers to participation" for delegates from the southern hemisphere.

[13] Riley Whitelum and his wife, Elayna Carausu, two Australians who had been sailing around the world aboard their 48-foot (15 m) catamaran, La Vagabonde, took Thunberg back across the Atlantic.

"[14][15][16][17] Speaker of the US House of Representatives Nancy Pelosi led a 15-member Congressional delegation to the talks to demonstrate continued U.S. support for the negotiations, despite the Trump administration's decision to pull the U.S. out of the Paris Agreement.

[20] The last part of the Paris regime that remains to be resolved is Article 6, which describes rules for a carbon market and other forms of international cooperation.

[22] According to scientists, talks focused on some of the rules for implementing the 2015 Paris agreement, but the overriding issue of how fast the world needs to cut greenhouse gas emissions has received little official attention.

[27][28] Greenpeace executive director Jennifer Morgan summarized the prevalent opinion: “Climate blockers like Brazil and Saudi Arabia, enabled by an irresponsibly weak Chilean leadership, peddled carbon deals and steamrolled scientists and civil society”.

For example, the Climate Ambitious Coalition contains now "73 countries committed to net zero emissions by 2050, as well as a further 1214 actors (regions, cities, businesses, investors) who have pledged the same goal".

[36] The goal of the ongoing song collaboration is to celebrate human culture and put pressure on world governments to enact New Year's resolutions to resolve the climate crisis.
