COP30: Brazil, Chile, Canada, Others Sign Declaration to Fight Climate Disinformation

Thirteen countries have signed the “Declaration on Information Integrity on Climate Change” at COP30 in Belém, Brazil, aiming to combat climate disinformation and promote science-based information.

Launched by the Global Initiative for Information Integrity on Climate Change on Wednesday, the declaration commits governments, civil society, and the private sector to transparency, protection of journalists and researchers, and dissemination of evidence-based climate information. Signatories include Brazil, Canada, Chile, Denmark, Finland, France, Germany, Spain, Sweden, Uruguay, Belgium, and two others.

Brazilian President Luiz Inácio Lula da Silva warned that climate change “is no longer a threat of the future; it is a tragedy of the present,” condemning attacks on scientific evidence and institutions.

United Nations Secretary-General António Guterres urged stronger action against misinformation, online harassment, and greenwashing, saying, “Scientists and researchers should never fear telling the truth.”

UNESCO Director-General Audrey Azoulay highlighted the risks faced by journalists and researchers covering climate issues, noting that reliable information is essential to overcome climate disruption.

The declaration calls for government support for research on information integrity, particularly in developing countries, and urges private companies to adopt responsible communication and advertising practices. The Global Initiative said climate disinformation remains a major threat, undermining public trust and delaying progress toward sustainable solutions.
