Big Tech’s AI Climate Hoax: 74% of industry’s claims about AI’s climate benefits are unproven
A critical analysis of industry’s statements on AI and climate impact found 36% of claims that AI benefits the climate did not cite any evidence at all
A staggering 74% of claims about AI’s climate benefits are unproven, according to “The AI Climate Hoax: Behind the Curtain of How Big Tech Greenwashes Impacts.”
Only 26% of the 154 claims from companies like Google and Microsoft and institutions such as the International Energy Agency in the research cited published academic papers, and 36% of claims that AI benefits the climate did not cite any evidence at all.
The analysis did not uncover a single example where consumer generative systems such as ChatGPT, Gemini, or Copilot were leading to a material, verifiable, and substantial level of emissions reductions.
The report was commissioned and published by a consortium of environmental organisations including Beyond Fossil Fuels, Climate Action Against Disinformation (CAAD), Friends of the Earth U.S., Green Screen Coalition, Green Web Foundation, and Stand.earth, and was authored by climate and energy analyst Ketan Joshi.
The accelerated growth of AI is increasing pressure on the climate, and Big Tech must take responsibility for mitigating its environmental impacts. Companies must disclose their energy consumption and emissions, and be transparent about the environmental and social justice impacts of their technologies, and whether data centres are really serving the critical needs of society.
Ketan Joshi, Independent climate and energy analyst: “It appears tech companies are using vagueness about what happens within energy-hogging data centres to greenwash a planet-wrecking expansion. This has bled through into organisations like the International Energy Agency. The promises of planet-saving tech remain hollow, while AI data centres breathe life into coal and gas every day. These claims of climate benefit are unjustified and overhyped, and could cover up irreversible damage being done to communities and society.”
Jill McArdle, Beyond Fossil Fuels: “Big Tech’s AI hype is distracting users from the rapid and dangerous expansion of giant, energy and water-intensive data centres, while the tech industry’s huge energy demands are throwing the fossil fuel industry a lifeline. There is simply no evidence that AI will help the climate more than it will harm it. Rather than relying on credible and substantiated data, Big Tech companies are writing themselves a blank cheque to pollute on the empty promise of future salvation. We cannot bet the climate on these baseless claims.”
Michael Khoo, Policy co-chair, Climate Action Against Disinformation, Program Director, Friends of the Earth U.S.: “Any climate benefits are far outweighed by how much energy generative AI is using. By lumping traditional and generative AI together, possible climate solutions are bundled with extreme pollution, and presented as a package deal. Governments must require basic transparency from the AI industry so communities and scientists can know how much energy is being exploited for this technology.”
Nathan Taft, Senior Campaigner Stand.earth: “The sheer scale of these AI data center buildouts could have global implications for the climate, and it also comes with serious impacts for local communities. The least these corporations can do is ensure that demand isn’t met with fossil fuels that pollute local communities. Hyperscalers can’t hand-wave away community concerns with sleight-of-hand promises of future clean energy, or greenwash its ongoing love affair with fossil fuels — these new data centers must be backed by new, locally sourced, 24/7 renewable energy before they go online, or not go online at all.”
