The Amazon Cooperation Treaty Organization (ACTO) is an intergovernmental organization that brings together the eight Amazonian countries — Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela.
United by the Amazon Cooperation Treaty, we work to strengthen regional cooperation and promote the sustainable development of the Amazon and the well-being of its peoples.
Our History
It all began in 1978, with the signing of the Amazon Cooperation Treaty — the first international agreement aimed at the joint protection and development of the Amazon.
In 1998, the Treaty was institutionally strengthened with the creation of ACTO, marking a new phase of regional cooperation.
Since 2003, our Permanent Secretariat, based in Brasília, has coordinated regional actions and given life to the commitments undertaken by the countries.
Since then, the Organization has evolved with new political mandates, reaffirmed in the Belém (2023) and Bogotá (2025) Declarations, which consolidate ACTO as a permanent platform for joint action for the Amazon.
Our Milestones

Meeting of Presidents of the Amazonian Countries
Although it is not a formal instance of the Treaty, it has become an essential political forum. It is a high-level space that promotes dialogue on shared interests, the exchange of perspectives on regional challenges, and the building of consensus to guide joint policies and strategies for the Amazon.
Over time, these meetings have marked important milestones:

Amazonian Governance under the New Mandates
ACTO’s governance model is based on cooperation, respecting the sovereignty of the Amazonian countries and promoting coordinated actions for the benefit of the region.
This governance has been strengthened by the political mandates established in the Belém and Bogotá Declarations, which expanded ACTO’s role as a regional platform for coordination, political dialogue, and technical cooperation.
Through this structure, ACTO works to implement political mandates, strengthen national capacities, and consolidate sustainable management for the region.
Member Countries
ACTO brings together eight Amazonian countries — Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela — united by the shared commitment to protect the Amazon and promote the sustainable development of the region.
These countries share the largest tropical biome on the planet, home to more than 50 million people and containing around 20% of the world’s fresh water.
Spanning over 7.5 million km² of forest, it encompasses a unique diversity of peoples, cultures, and ecosystems that sustain life and global climate balance.
