Data centres carbon emissions
Archived — this story has rotated out of today’s deck. It is kept here in full.
The gist
Two UK data centres will emit 4.5m tonnes of carbon yearly, exceeding ExxonMobil's UK emissions.
This shows AI's power hunger threatens climate goals, sparking calls for regulation.
Background
The analysis by non-profit Foxglove found that two planned data centres in Buckinghamshire and Bedfordshire will use 1.3GW of power and produce over 4.5 million tonnes of carbon emissions annually when fully operational. This exceeds ExxonMobil's UK emissions of 3.9 million tonnes in 2023, according to Ember. The findings come amid growing concern about the environmental impact of data centres, driven by the AI boom, with tech giants like Microsoft, Google, and Amazon reporting significant emissions increases.
How it unfolded
- Aug 25, 2026The Guardian publishes exclusive analysis by Foxglove revealing the two data centres' emissions exceed ExxonMobil's UK total.
- Aug 25, 2026Wood Mackenzie reports China's AI boom will drive data centre power demand to 774 TWh by 2030.
- Aug 26, 2026Fortune reports on underwater data centres as a response to land and cooling challenges, but notes they don't eliminate carbon emissions.
- Aug 27, 2026Bisnow reports EPA moves to cut public review rules for data centre emissions, amid backlash.
- Aug 30, 2026Sierra Club article highlights hidden AI carbon emissions from oil and gas AI use, pushing for 'enabled emissions' regulation.
Who’s saying what
- Official
- Toby Perkins, Labour MP and chair of the environmental audit committee, calls the analysis a 'potent reminder' that data centres could threaten legally binding climate goals.
- Analysts
- Wood Mackenzie forecasts data-centre carbon emissions will peak by 2035 as renewable penetration increases.
- Expert
- Alpine and coauthors argue 'enabled emissions' from AI in oil and gas must be regulated, as current market dynamics don't prevent lock-in.
- Caution
- Samuel Dotson of Union of Concerned Scientists suggests efficiency gains may not automatically lead to net emissions reductions.
Still unverified
The specific emissions figures for the two data centres are based on Foxglove's analysis, which has not been independently verified. The claim that emissions exceed ExxonMobil's UK total relies on Ember's 2023 data.
