AI data centres could undermine UK's emissions goals

The UK government's ambition of achieving net zero carbon emissions by 2050 could be undermined by its new deal on AI data centres, according to BBC research.

During Wednesday's Budget speech, Chancellor John Healey said data centres would be allowed to build onsite power generation while they wait for a grid connection.

BBC File on 4 Investigates has discovered that four planned "hyperscale" data centres - including three in the south of England - are already considering using gas-fired power to meet their electricity needs, creating more CO2 than the cities of Manchester, Liverpool and Southampton combined.
