Claims that AI can help fix climate dismissed as greenwashing
Tech companies are conflating traditional artificial intelligence with generative AI when claiming the energy-hungry technology could help avert climate breakdown, according to a report.Most claims that AI can help avert climate breakdown refer to machine learning and not the energy-hungry chatbots and image generation tools driving the sector’s explosive growth of gas-guzzling datacentres, the analysis of 154 statements found.The research, commissioned by nonprofits including Beyond Fossil Fuels and Climate Action Against Disinformation, did not find a single example where popular tools such as Google’s Gemini or Microsoft’s Copilot were leading to a “material, verifiable, and substantial” reduction in planet-heating emissions.Ketan Joshi, an energy analyst and author of the report, said the industry’s tactics were “diversionary” and relied on tried and tested methods that amount to “greenwashing”.He likened it to fossil fuel companies advertising their modest investments in solar panels and overstating the potential of carbon capture.
“These technologies only avoid a minuscule fraction of emissions relative to the massive emissions of their core business,” said Joshi.“Big tech took that approach and upgraded and expanded it.”Most of the claims that were scrutinised came from an International Energy Agency (IEA) report, which was reviewed by leading tech companies, and corporate reports from Google and Microsoft.The IEA report – which devoted two chapters to the potential climate benefits of traditional AI – had a roughly even split between claims that rested on academic publications, corporate websites and those that had no evidence, according to the analysis.For Google and Microsoft, most claims lacked evidence.
The analysis, released during the AI Impact Summit in Delhi this week, argues the tech industry has misleadingly presented climate solutions and carbon pollution as a package deal by “muddling” types of AI.Sasha Luccioni, AI and climate lead at Hugging Face, an open-source AI platform and community, who was not involved in the report, said it added nuance to a debate that often lumped very different applications together.“When we talk about AI that’s relatively bad for the planet, it’s mostly generative AI and large language models,” said Luccioni, who has pushed the industry to be more transparent about its carbon footprint.“When we talk about AI that’s ‘good’ for the planet, it’s often predictive models, extractive models, or old-school AI models.”Green claims even for traditional AI tended to rely on weak forms of evidence that had not been independently verified, the analysis found.
Only 26% of the green claims that were studied cited published academic research, while 36% did not cite evidence at all,One of the earliest examples identified in the report was a widespread claim that AI could help mitigate 5-10% of global greenhouse gas emissions by 2030,The figure, which Google repeated as recently as April last year, came from a report it commissioned from BCG, a consulting firm, which cited a blogpost it wrote in 2021 that attributed the figure to its “experience with clients”,Datacentres consume just 1% of the world’s electricity but their share of US electricity is projected to more than double to 8,6% by 2035, according to BloombergNEF.
The IEA predicts they will account for at least 20% of the rich world’s growth in electricity demand to the end of the decade.While the energy consumption of a simple text query to a large language model such as ChatGPT may be as little as running a lightbulb for a minute, partial industry disclosures suggest, it rises considerably for complex functions such as video generation and deep research, and has troubled some energy researchers with the speed and scale of its growth.A spokesperson for Google said: “Our estimated emissions reductions are based on a robust substantiation process grounded in the best available science, and we have transparently shared the principles and methodology that guide it.”Microsoft declined to comment, while the IEA did not respond to requests for comment.Joshi said the discourse around AI’s climate benefits needed to be “brought back to reality”.
“The false coupling of a big problem and a small solution serves as a distraction from the very preventable harms being done through unrestricted datacentre expansion,” he said.The best public interest journalism relies on first-hand accounts from people in the know.If you have something to share on this subject, you can contact us confidentially using the following methods:The Guardian app has a tool to send tips about stories.Messages are end to end encrypted and concealed within the routine activity that every Guardian mobile app performs.This prevents an observer from knowing that you are communicating with us at all, let alone what is being said.

US and Japan unveil $36bn of oil, gas and critical minerals projects in challenge to China
Japan has drawn up plans for investments in US oil, gas and critical mineral projects worth about $36bn under the first wave of a deal with Donald Trump.The US president and Sanae Takaichi, Japan’s prime minister, announced a trio of projects including a power plant in Portsmouth, Ohio, billed by the Trump administration as the largest natural gas-fired generating facility in US history.As a diplomatic row between Japan and China over the security of Taiwan continues, testing the Japanese economy, Takaichi said the projects would strengthen her country’s ties with the US.While Takaichi did not directly mention China, she expressed hope in a statement that the investments would enhance Japanese and US economic security.“Our massive trade deal with Japan has just launched,” Trump declared in a social media post
The death of Heather Preen: how an eight-year-old lost her life amid sewage crisis
In 1999, Heather Preen contracted E coli on a Devon beach. Two weeks later she died. Now, as a new Channel 4 show dramatises the scandal, her mother, Julie Maughan, explains why she is still looking for someone to take responsibilityWhen Julie Maughan was invited to help with a factual drama that would focus on the illegal dumping of raw sewage by water companies, she had to think hard. In some ways, it felt 25 years too late. In 1999, Maughan’s eight-year-old daughter, Heather Preen, had contracted the pathogen E coli O157 on a Devon beach and died within a fortnight
Boost to British Steel as Turkey places high-speed rail order
British Steel has secured an order worth tens of millions of pounds to supply rail for a high-speed electric railway in Turkey, amid continuing uncertainty over the long-term future of the government-controlled steelworks in Scunthorpe.The site will supply 36,000 tonnes of rail to ERG International Group, the company announced, in what it called an “eight-figure agreement”.The rail is destined for a 599km railway line being built to connect the Turkish capital, Ankara, with the western port city of İzmir, which will reduce the travel time and cut carbon emissions.British Steel said securing the contract had allowed it to create 23 new roles at the north Lincolnshire site and to restart round-the-clock rail manufacturing for the first time in more than a decade.The deal, which was supported by UK Export Finance, is seen as a commercial boost for the loss-making manufacturer
Goldman Sachs to drop race, gender and LGBTQ+ criteria from board evaluations
Goldman Sachs is removing race, gender and other diversity-related considerations when evaluating prospective candidates for its executive board after pressure from an activist shareholder group to remove the criteria.The National Legal and Policy Center (NLPC), a small Goldman shareholder, quietly submitted a request to the company last September asking the bank to eliminate its diversity, equity and inclusion (DEI) board criteria.According to a Wall Street Journal report, Goldman recently informed the group that it plans to remove the DEI criteria, and the two parties signed an agreement under which the NLPC would withdraw its proposal.Goldman’s board is expected to approve the changes this month, people familiar with the matter told the Journal.Currently, the board’s governance committee evaluates qualified candidates based primarily on four factors
UK interest rate cut likely in March as unemployment rate rises; youth joblessness to ‘increase significantly’ in coming months – as it happened
The chances of a cut to UK interest rates next month have risen, following this morning’s data showing a rise in unemployment and a slowdown in wage growth.The City money markets now indicate there’s a near-75% chance that the Bank of England lowers interest rates to 3.5% at its next meeting, in March, up from 69% last night.Investors now fully expect two rate cuts by Christmas, which would bring Bank Rate down to 3.25%
Surging prediction markets face legal backlash in US: ‘Lines have been blurred’
State lawmakers and gaming regulators across the US are escalating their fight against prediction markets, arguing that the fast-growing platforms are “basically gambling but with another name”.At least 20 federal lawsuits have been filed nationwide, disputing whether companies such as Kalshi and Polymarket should be treated as federally regulated financial exchanges, as they maintain, or as gambling operations that should be regulated like state-licensed sportsbooks.The row escalated this week, when the chair of the US Commodity Futures Trading Commission (CFTC), which oversees these platforms, announced that it was filing a friend-of-the-court brief in defense of “its exclusive jurisdiction over these derivative markets’”.The legal battle comes as the sector surges. More than $1bn was traded on Kalshi alone during Super Bowl Sunday, and Bloomberg reported that Kalshi’s January trading volume reached nearly $10bn, most of it tied to sports
