Countries Move to Curb Online Climate Disinformation as COP30 Highlights Rising Risks

In a significant diplomatic development, twelve nations, including Brazil, Canada, France, Germany, and Spain, have united behind the first Declaration on Information Integrity on Climate Change, acknowledging that combating misinformation has become as crucial as reducing carbon emissions in the fight against climate change.

Brazilian President Luiz Inácio Lula da Silva highlighted the growing challenge of false information infiltrating climate debates, noting how rapidly misleading claims can spread across digital platforms and undermine global climate action efforts.

The declaration represents a formal commitment by signatory countries to support environmental journalists, scientists, and researchers while strengthening international cooperation against organized attempts to distort climate science. This initiative emerged from a partnership between Brazil, the United Nations Department of Global Communications, and UNESCO.

João Brant, Brazil’s Secretary for Digital Policies, described the effort as building “a wave of truth” that relies on research, effective public communication, and coordinated responses to counter misleading narratives that have increasingly plagued climate discussions.

Speaking to UN News, Frederico Assis, COP30’s Special Envoy for Information Integrity, expressed concern about how disinformation influences various aspects of climate action, from diplomatic negotiations to public engagement. Assis specifically pointed to algorithms that amplify unverified content as a particular challenge. The initiative aims to foster broader cooperation among governments, civil society organizations, and media outlets.

UNESCO representative Guilherme Canela emphasized the importance of understanding how climate-related falsehoods spread and identifying their financial backers. As part of this effort, a global fund established under the program has already attracted hundreds of proposals for investigative journalism and research projects, with nearly two-thirds coming from developing nations. Brazil has taken a leadership role by contributing an initial one million dollars to support selected projects.

Maria Clara Moraes, a UN Verified Champion and co-founder of the Marias Verdes platform, offered insight into the evolving tactics of climate disinformation campaigns. According to Moraes, these campaigns frequently shift their approaches but often aim to convince audiences that international cooperation on climate change is ineffective. Despite these challenges, she noted encouraging trends, including growing interest among younger users in science-based content and the potential impact of individual choices in supporting accurate information.

The initiative comes at a critical time when climate change disinformation threatens to derail progress on global climate agreements and action plans. Digital platforms have become battlegrounds where scientific consensus competes with orchestrated campaigns of doubt and denial, often backed by entities with vested interests in maintaining fossil fuel dependency.

This international effort also aligns with findings from the Global Multidimensional Poverty Index (MPI), which reveals that countries currently experiencing the highest levels of multidimensional poverty are projected to face the most severe temperature increases by the century’s end. The MPI report advocates for integrating poverty reduction strategies with climate mitigation, adaptation efforts, and ecosystem restoration to create solutions that benefit both vulnerable populations and the planet.

The declaration marks a significant step in recognizing information integrity as a fundamental component of effective climate action, acknowledging that public understanding and support are essential for implementing the transformative policies needed to address the climate crisis.
