COP30 Takes Aim at Climate Disinformation Threatening Global Action

At a pivotal moment in the global climate conversation, Brazil’s President Luiz Inácio Lula da Silva has issued a stark challenge at the opening session of COP30: the battle for truth has become as critical as the fight to reduce emissions. “COP30 must mark a new defeat for climate denialists,” he declared, setting a combative tone for the summit.

In a landmark move, twelve nations including Brazil, Canada, France, Germany, and Spain signed the first-ever Declaration on Information Integrity on Climate Change on Wednesday. This watershed agreement commits signatories to combat the proliferation of false climate information and protect those who stand on the frontlines of truth: environmental journalists, scientists, and researchers.

The declaration, unveiled as part of the Global Initiative for Information Integrity on Climate Change, outlines concrete steps to dismantle networks spreading climate misinformation while shielding evidence-based voices from harassment and attacks. João Brant, Brazil’s Secretary for Digital Policies, framed the objective in simple yet urgent terms: to “create a wave of truth.”

Launched in June as a partnership between Brazil, the UN Department of Global Communications, and UNESCO, the initiative represents a coordinated international response to what many see as an existential threat to climate action.

Frederico Assis, COP30’s Special Envoy for Information Integrity, emphasized the grave stakes. “Disinformation, driven by obscurantist worldviews, fuels political extremism and puts lives at risk,” he told UN News, warning of potential interference in climate negotiations. “There is broad recognition that disinformation can affect and compromise every part of the COP process – diplomatic negotiations, the action agenda, or mobilization and summits. All our efforts will be at risk if we fail to tackle disinformation properly.”

Assis highlighted the role of algorithms in amplifying “conspiratorial and manipulative” content, often using sophisticated tactics to spread falsehoods. His mandate centers on keeping the issue in the public eye while mobilizing a diverse coalition of political, religious, social leaders, civil society, and media to push back against climate misinformation.

In a notable development, information integrity has secured a place on the official COP agenda for the first time – a milestone that UNESCO’s Guilherme Canela describes as long overdue. Speaking to UN News, Canela emphasized that the global initiative aims to expose the machinery driving climate disinformation.

“We still know very little about what’s behind this,” Canela explained. “For example, who funds these posts, and why do they spread faster than other types of content? How does that happen? If we don’t understand these mechanisms, it’s very difficult to design effective strategies to combat this phenomenon.”

The initiative has established the Global Fund for Information Integrity on Climate Change, which has already attracted 447 proposals from nearly 100 countries. With initial funding of $1 million from Brazil, the fund is supporting its first round of projects, with almost two-thirds coming from developing nations.

Maria Clara Moraes, a UN Verified Champion and co-founder of the Marias Verdes platform with over half a million TikTok followers, described the battle against climate disinformation as “completely possible, but also extremely challenging.” She warned that these campaigns are highly organized and “backed by powerful forces, particularly the fossil fuel industry,” with narratives that continuously adapt and “change their disguise” over time.

“There are several types of disinformation,” Moraes noted. “One of the most powerful is saying that it’s too late – that nothing can be done, or that these events like COP30 don’t make a difference. That’s also disinformation. Saying, ‘This isn’t working, it’s too slow, too complex, too frustrating.’ But yes – it’s important. We must constantly reaffirm the value of multilateralism and the importance of spaces like this one.”

Despite the formidable challenges, Moraes sees hope in younger generations. By producing content rooted in science and sustainability, she believes awareness of the climate emergency is growing rapidly. She points to young people as “a great source of hope and optimism” and encourages everyone to create “micro-revolutions” through everyday choices that support climate action and drive systemic change.

As COP30 progresses, this unprecedented focus on information integrity signals a recognition that the climate crisis cannot be effectively addressed without simultaneously confronting the crisis of climate misinformation that threatens to undermine global action.
