The Brazilian Academy of Sciences, in partnership with IANAS and with the support of IAP, organized the event “A Scientific Call for COP30: Science Academies United for Climate Action” from October 20–22 in Manaus, Brazil. This landmark scientific meeting was held in preparation for the 30th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP30), scheduled for November 10–21, 2025, in Belém do Pará.

The Manaus event brought together leading researchers from Brazil and abroad, representatives of science academies from the Americas, Africa, Asia, and Europe, as well as international institutions dedicated to tropical forest and climate research. Participants engaged in in-depth discussions on critical issues, including:

• Climate change adaptation
• Forest and biodiversity conservation
• Climate justice and social impacts
• International scientific collaboration

The event concluded with the release of a joint statement of recommendations prepared by the participating organizations. Signed by 42 entities (38 science academies and 4 IAP regional networks), the statement aims to contribute to and inform the COP30 deliberations. By uniting the collective voice of science academies worldwide, the initiative seeks to strengthen the role of science in shaping climate policy and promoting sustainable futures.
