"The UK's cumulative 10-year greenhouse gas emissions from AI compute could range from 34 to 123 MtCO₂ - this is around 0.9-3.4% of the UK's projected total emissions over the 10-year period."
"The earlier numbers appear to have been annual and the recent revision a 10-year figure, which makes an increase in the estimate of around 100x."
"Carbon Brief has calculated that emissions could in fact be somewhere between 3.4 MtCO₂ and significantly higher, depending on the energy sources used."
Recent revisions to carbon emissions projections for datacentres show an increase of around 100 times the initial estimates. The Department for Science, Innovation & Technology initially estimated emissions from AI compute to be between 0.025 and 0.142 MtCO₂ by 2035. However, the corrected figures indicate a range of 34 to 123 MtCO₂ over a 10-year period, representing 0.9-3.4% of the UK's total emissions. Further analysis suggests these revised figures may still be optimistic, particularly if gas is involved in electricity generation.
