AI boom has caused same CO2 emissions in 2025 as New York City, report claims

The AI boom has caused as much carbon dioxide to be released into the atmosphere in 2025 as emitted by the whole of New York City, it has been claimed.The global environmental impact of the rapidly spreading technology has been estimated in research published on Wednesday, which also found that AI-related water use now exceeds the entirety of global bottled-water demand.The figures have been compiled by the Dutch academic Alex de Vries-Gao, the founder of Digiconomist, a company that researches the unintended consequences of digital trends.He claimed they were the first attempt to measure the specific effect of artificial intelligence rather than datacentres in general as the use of chatbots such as OpenAI’s ChatGPT and Google’s Gemini soared in 2025.The figures show the estimated greenhouse gas emissions from AI use are also now equivalent to more than 8% of global aviation emissions.

His study used technology companies’ own reporting and he called for stricter requirements for them to be more transparent about their climate impact.“The environmental cost of this is pretty huge in absolute terms,” he said.“At the moment society is paying for these costs, not the tech companies.The question is: is that fair? If they are reaping the benefits of this technology, why should they not be paying some of the costs?”De Vries-Gao found that the 2025 carbon footprint of AI systems could be as high as 80m tonnes, while the water used could reach 765bn litres.He said it was the first time AI’s water impact had been estimated and showed that AI water use alone was more than a third higher than previous estimates of all datacentre water use.

The figures are published in the academic journal Patterns,The International Energy Agency (IEA) said earlier this year that AI-focused datacentres draw as much electricity as power-thirsty aluminium smelters and datacentre electricity consumption is expected to more than double by 2030,“This is yet more evidence that the public is footing the environmental bill for some of the richest companies on Earth,” said Donald Campbell, the director of advocacy at Foxglove, a UK non-profit that campaigns for fairness in tech,“Worse, it is likely just the tip of the iceberg,The datacentre construction frenzy, driven by generative AI, is only getting started.

“Just one of these new ‘hyperscale’ facilities can generate climate emissions equivalent to several international airports,And in the UK alone, there are an estimated 100-200 of them in the planning system,”The IEA has reported that the largest AI-focused datacentres being built today will each consume as much electricity as 2m households with the US accounting for the largest share of datacentre electricity consumption (45%) followed by China (25%) and Europe (15%),The largest datacentre being planned in the UK, at a former coal power station site in Blyth, Northumberland, is expected to emit more than 180,000 tonnes of CO2 a year when at full operation – the equivalent to the amount produced by more than 24,000 homes,In India, where $30bn (£22.

5bn) is being invested in datacentres, there are growing concerns that a lack of reliability from the National Grid will mean the construction of huge diesel generator farms for backup power, which the consultancy KPMG this week called “a massive … carbon liability”,Technology companies’ environmental disclosures are often insufficient to assess even the total datacentre impact, never mind isolating AI use, said De Vries-Gao,He noted that when Google recently reported on the impact of its Gemini AI, it did not account for the water used in generating the electricity needed to power it,Google reported that in 2024 it managed to reduce energy emissions from its datacentres by 12% due to new clean energy sources, but it said this summer that achieving its climate goals was “now more complex and challenging across every level – from local to global” and “a key challenge is the slower-than-needed deployment of carbon-free energy technologies at scale”,Google was approached for comment.

‘Permanent winter’: a day in the life of a hospital dealing with flu and strikes

Thirteen ambulances are lined up at the rear of the emergency department (ED) of the Royal Stoke university hospital, Staffordshire, as Ann-Marie Morris, the hospital trust’s deputy medical director, walks towards the entrance, squinting in the low afternoon sun. Behind the closed door of each vehicle is a sick patient, some of whom have been waiting for four hours or more, backed up in the car park, just to get in the door.The reason they are stuck out here is that there are no beds in the ED – and there is not much corridor space, either. In the tight foyer, a cluster of ambulance staff and a senior nurse in hi-vis are huddled around a computer station. Behind them, a corridor stretches into the ward, where at least six or seven beds are lined up head to toe along one side, each occupied by a patient

Some of England’s most-deprived councils to get funding boost in new deal

Some of England’s most-deprived councils will receive a funding boost under a new three-year local government deal which prioritises urban areas with high social needs at the expense of affluent places in the leafy south-east.Manchester, Birmingham, Luton, Bradford, Coventry, Derby and outer London boroughs such as Haringey and Enfield will receive big spending power increases under what ministers have described as a fairer system that will “restore pride and opportunity in left-behind places”.The housing and communities secretary, Steve Reed, said: “This is a chance to turn the page on a decade of cuts, and for local leaders to invest in getting back what has been lost – to bring back libraries, youth services, clean streets, and community hubs.”However, the settlement got a lukewarm welcome from some urban councils in the north and Midlands which said it was disappointing that “London’s suburbs” were the “biggest winners” from the review, “leaving many of the most deprived communities facing further cuts after a decade of austerity”.Leaders of county councils in English home counties and rural areas also criticised the settlement, describing it as unfair because it disproportionately benefited urban ones

Rights group challenges trans-inclusive swimming policy at Hampstead Heath

Rules permitting trans women to share female changing facilities and swim in a women-only pond are discriminatory and unlawful, the high court has heard.The City of London Corporation is breaching equality legislation by allowing trans people to use the single-sex ponds on Hampstead Heath, according to a claim brought by the rights group Sex Matters. It is seeking permission to challenge the admission regulations.Daniel Stilitz KC, for the City of London, said Sex Matters had “steamed in”, bringing a premature legal action at a time when its officials were actively consulting pond users on its entry rules.Public bodies are redrafting their policies on single-sex spaces in response to the supreme court’s ruling in April that the legal definition of a woman is based on biological sex

Will resident doctors lose support over latest strike? | Letters

“Striking resident doctors are digging in. History suggests this will go on and on” says the headline on Denis Campbell’s analysis piece (16 December). As a retired public health research and policy adviser and the parent of a doctor currently in core training, I agree that it is likely to go on and on – but not because doctors are stubborn. It will persist because the numbers do not add up and too much of the response has been political posturing rather than workforce planning.This year, around 30,000 doctors competed for just 10,000 specialty training posts, leaving thousands unable to progress

When ‘How are you?’ becomes a painful question to answer | Letter

It’s not just Germans like Carolin Würfel (16 December) who face a challenge with the question “How are you?” When I was diagnosed with metastatic prostate cancer, that question went from being a routine conversation-opener to something much trickier.The convention, in Britain at least, is to answer something like “Oh, not bad…” Frankly, things are very bad, so I’m stuck between the dishonesty of the ritual reply and the full truth, which is a lot to fling back at someone offering an innocent greeting. I’ve developed the more nuanced response “All right today”, which I use if I really am doing all right in the general context of things.Some days are genuinely rotten, in which case it remains a struggle to work out what to say, but the rest of the time I try to respond relative to my “new normal”. Some days I still have joyous events and upbeat feelings, in which case I’d stretch to a buoyant “Pretty good today”, but always I feel compelled to append the word “today” as a matter of honesty about the future

Study finds 10% of over-70s in UK could have Alzheimer’s-like changes in brain

One in 10 people in the UK aged 70 and older could have Alzheimer’s-like changes in their brain, according to the clearest, real-world picture of how common the disease’s brain changes are in ordinary, older people.The detection of the proteins linked with the disease is not a diagnosis. But the findings indicate that more than 1 million over-70s would meet Nice’s clinical criteria for anti-amyloid therapy – a stark contrast to the 70,000 people the NHS has estimated could be eligible if funding were available.Experts, including those from Alzheimer’s Research UK, have said the findings from the first-ever population-based research into the disease have huge potential for early and accurate diagnosis.“High-quality studies like this are crucial to enhancing our understanding of how blood tests for Alzheimer’s could be used in clinical practice,” said David Thomas, the head of policy and public affairs at Alzheimer’s Research UK
