Negotiators in Belém, Brazil, opened COP30 with a stark warning: the race to avert catastrophic global heating is being sabotaged by a surge of climate disinformation. The falsehoods, spreading faster than ever online, threaten to derail fragile progress on climate action.
Brazil’s President Luiz Inácio Lula da Silva set the tone at the opening session, declaring that the battle for truth has become just as critical as the fight to cut emissions. COP30 must mark “a new defeat for climate denialists,” he said.
On Wednesday, 12 nations – including Brazil, Canada, France, Germany and Spain – signed onto the first-ever Declaration on Information Integrity on Climate Change, pledging to fight back against the flood of false content and protect those on the frontlines of truth: environmental journalists, scientists and researchers.
The declaration, unveiled under the Global Initiative for Information Integrity on Climate Change, calls for concrete steps to dismantle networks of climate lies and shield evidence-based voices from harassment and attacks.
João Brant, Brazil’s Secretary for Digital Policies, said the goal is simple but urgent: to “create a wave of truth.”
