This year’s UN climate summit in Brazil, COP30, is set against a backdrop of misinformation. Many are working to undermine efforts toward a swift shift from fossil fuels to cleaner energy sources.
With the U.S. having the highest historical carbon emissions, President Trump’s rhetoric poses a significant challenge. He has been vocal on social media, spreading false claims about wind energy, like suggesting turbines cause health issues. His administration promotes fossil fuels as “affordable and reliable,” but this narrative overlooks critical facts: burning coal, gas, and oil damages our climate, leading to extreme weather events such as droughts and floods.
Data shows that clean energy is the way forward. For every dollar invested in renewables, we gain three times more jobs compared to fossil fuels. This economic potential counters the narrative that renewable energy harms job growth.
Kathy Mulvey from the Union of Concerned Scientists points out that the Trump administration employs outdated tactics reminiscent of the fossil fuel industry’s denial strategies from the 1980s. Just like tobacco companies downplayed smoking’s risks, some energy companies aim to create doubt about climate science.
Historical context adds depth to our understanding. In 2022, COP29 in Azerbaijan saw an overwhelming presence of fossil fuel lobbyists—over 1,770 registered, surpassing almost all country delegates. This infiltration highlights the ongoing struggle against misinformation.
As part of efforts to tackle this disinformation, Brazil initiated the Global Initiative for Information Integrity on Climate Change at COP30. This program aims to fund research and promote accurate climate communication. UN Secretary-General Antonio Guterres emphasized the need for clear information to combat false narratives and support genuine progress on climate issues.
Experts recognize that fighting misinformation is crucial, especially as fossil fuel production is anticipated to double by 2030. The Production Gap Report warns this trajectory jeopardizes global climate goals.
Interestingly, social media trends reveal a sharp rise in discussions about climate disinformation, particularly in France. Reports indicated that instances of misinformation there tripled in 2025, reflecting a concerning global pattern.
Communications co-chair of the Climate Action Against Disinformation coalition, Philip Newell, urges Big Tech and media outlets to filter misleading content about climate change. He believes transparency is vital to protect public discourse from manipulation.
Eliesio Marubo, a Brazilian Indigenous rights lawyer, insists we must confront misinformation directly at COP30. Instead of labeling it “fake news,” he argues we should call it what it is: deliberate falsehoods.
As the challenge of climate change grows, so does the need for clearer, more honest communication. Only by highlighting reliable information can we foster trust and drive effective action against climate change.
