Officials Hugely Underestimated Impact of AI Datacentres on UK Carbon Emissions
Revised figures increase fears about energy-intensive datacentres worsening climate emergency

TL;DR
- UK government's estimated carbon emissions from AI datacentres have increased by over 100 times.
- New estimates suggest AI datacentres could emit 34m to 123m tonnes of CO₂ over 10 years.
- This impact could represent 0.9% to 3.4% of the UK's total projected emissions from 2025 to 2035.
- Previous estimates were significantly lower, claiming a maximum of 0.142m tonnes of CO₂ in a single year.
- The revision was prompted by watchdog investigations highlighting potential underestimations.
- AI datacentres require substantial electricity, much of which is still generated by fossil fuels.
- The scale of AI buildout could potentially double the UK's electricity consumption.
- There are concerns about the conflict between embracing AI datacentres and the UK's net zero by 2050 commitment.
