2023 Amazon Cooperation Treaty Organization Summit

Companies, civic associations including indigenous ones, non-governmental organizations and non-ACTO member countries were invited by host Brazil to take part in the discussions.

Following years of international isolation in environmental matters under the presidency of Jair Bolsonaro during which environment policies were either loosened or scrapped, and disasters such as the 2019 Northeast Brazil oil spill and the Yanomami humanitarian crisis took place, Brazil sought to restore and update its environmental standards alongside regional and international partners from the beginning of the second presidency of Lula da Silva.

Governments and organizations also see the summit as an opportunity for developing countries to share their technologies and to unify and mutually support their strategies for climate justice in the international context, ahead of the COP28 and other negotiations.

[3][4] The ACTO member states are Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela.

[5] Five countries sent their Head of State, the exceptions being Ecuador, Suriname and Venezuela (the latter being represented by the Vice-President Delcy Rodríguez).
