The UK’s appetite for AI infrastructure could come at a hefty price as a proposed £10 billion data center at Elsham, Lincolnshire, could emit more greenhouse gases each year than five of the country’s busiest airports combined.
According to The Guardian, the data center is expected to house 15 enormous server halls and, at full capacity, is projected to produce vast amounts of carbon emissions, igniting debates on the environmental costs of the UK’s AI aspirations.
Is the UK chasing AI supremacy over green goals?
Plans submitted last month for the complex, located roughly nine miles east of Scunthorpe, estimate electricity use of around 3.7 billion kilowatt-hours annually, generating up to 857,254 tons of carbon emissions if powered by today’s National Grid mix. For perspective, that’s five times the carbon output of Birmingham Airport, take-offs and landings included. A public consultation on the scheme closes in three weeks.
Organizers acknowledge the extreme heat produced by so many high-performance computers and have proposed glasshouses to capture and reuse the waste warmth, in theory growing over 10 tons of tomatoes a day.
Yet building enough renewable generation on-site has been dismissed as impractical. Biomass would demand 100 lorry deliveries of wood chips daily; wind turbines would number 10,000 if each stood just 20 meters tall, and solar panels would need an area five times the size of the Glastonbury Festival grounds.
The backers, Elsham Tech Park Ltd, say they will “endeavor to purchase green power where possible” and hope that by the center’s anticipated opening in 2029, cleaner energy on the grid will cut actual emissions below today’s forecast.
A government spokesperson has underlined the need to meet AI’s power demands responsibly, pointing to advanced modular nuclear reactors as a “particularly important” solution, and promised planning reforms to accelerate nuclear builds nationwide.
Industry giants are already wrestling with these tensions. Microsoft admitted this week that despite a 2019 pledge to hit net-zero carbon by 2030, its overall emissions have climbed by 23%, driven largely by AI expansion.
Meta has just agreed to a 20-year power purchase deal with an Illinois nuclear station, while Amazon and Google are exploring their own nuclear ventures to secure low-carbon electricity for ever-hungry AI servers.
Experts want new data centers to trigger an equivalent rollout of renewables
Research paints an even starker picture of the sector as a whole. The Öko-Institut in Germany projects that by 2030, carbon emissions from AI data centers will be six times higher than in 2023.
Greenpeace argues that every new data center must trigger an equivalent rollout of renewables to prevent the carbon footprint of our digital lives from spiraling out of control.
Yet many experts believe AI itself could bolster the transition to a zero-carbon economy, optimizing power networks, accelerating materials discovery for clean technologies, or driving efficiencies across industry.
Martha Dark, co-executive director of London-based non-profit Foxglove, warns that Britain’s two big government objectives, fueling AI growth and hitting net zero by 2050, are now on a collision course.
“The prime minister has hailed generative AI data centers as miracle beans for our economy while also promising to purge toxic pollution and reach carbon neutrality,” she said.
“It’s decision time: does the government want a growth plan that truly benefits Britain, or one that best serves the interests of Amazon, Google and Meta?”

Local officials are keen to see the investment. Robert Waltham, leader of North Lincolnshire Council, stresses that data centers bring high-value jobs, Elsham Tech Park Ltd expects to employ around 900 people and can underpin crucial social services. His council is already piloting AI chatbots to help elderly residents manage their medications, helping them live independently for longer.
For its part, the developer highlights Elsham’s position amid the UK’s most advanced “clean energy cluster,” with access to a third of the nation’s offshore wind capacity and two-thirds of licensed carbon capture and storage sites.
Still, the debate over whether to prioritize rapid AI expansion or carbon reduction will only intensify as ministers press ahead with plans to fast-track both data centers and new nuclear capacity. In the coming weeks, the public consultation will reveal whether local voices side with the promise of high-paying tech jobs or with those who demand a greener path.
