Fifth Presidential Summit, the eight Amazonian countries, members of the Amazon Cooperation Treaty Organization (ACTO)

The Amazon Cooperation Treaty Organization (ACTO) is an intergovernmental organisation constituted by the eight Amazonian countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela that signed the Amazon Cooperation Treaty (ACT), establishing the only socio-environmental bloc in Latin America. Its mandate is to identify the medium-term priorities of the Amazonian countries, in line with the region’s economic, political, environmental, and social realities.

This year, the Amazon Regional Meeting was held in Bogotá, Colombia. Civil society, Indigenous Peoples and Local Communities, and governments came together at the Amazon Regional Meeting (18–22 August 2025), followed by the V Amazon Summit of Heads of State (22–23 August 2025). 

Both spaces continue the path set by the Belém Declaration (2023) and build momentum for UN Climate Change Conference (COP30) in Belém, Brazil this year. Still, binding commitments on fossil fuels and deforestation are missing, as is a civil society mechanism.
