Datacentre developers in the UK are encountering significant pressure to disclose how their projects might affect the nation's net greenhouse gas emissions. This concern has arisen primarily because the electricity demand from new AI infrastructure could potentially double the country's current needs. Campaign groups have formally addressed UK technology secretary Liz Kendall, highlighting that the escalating energy consumption required for these datacentres presents a serious threat to the UK's efforts to decarbonize its electricity grid.

The campaigners advocate for the developers to provide evidence that their projects will not lead to higher overall carbon dioxide emissions or contribute to local water scarcity issues. Their letter emphasizes the need for stringent accountability in energy usage as part of an upcoming national policy statement (NPS) regarding datacentres. They argue that without appropriate commitments and transparency from developers, the substantial electricity consumption associated with these facilities will inevitably lead to significant increases in climate emissions, undermining environmental sustainability goals.

The signatories of the letter include Foxglove, a group dedicated to challenging large tech companies, along with five other NGOs, such as Friends of the Earth. The growing momentum for stricter regulations on datacentre operations is highlighted by the involvement of MPs from the environmental audit committee, indicating a broader legislative interest in ensuring that the tech sector aligns with the UK's climate commitments. This scenario underscores a critical intersection of technology, environmental policy, and the urgent need for accountability in an era increasingly defined by high energy demands from the digital landscape.
