Letter to the Secretary of State for Energy Security and Net Zero relating to data centres and the Carbon Budget, 11 January

From: Environmental Audit Committee

Inquiry: The Seventh Carbon Budget

Summary

The Environmental Audit Committee Chair writes to the Secretary of State for Energy Security and Net Zero seeking clarification on whether data centres and their energy demand have been factored into the Seventh Carbon Budget and government planning. The Committee notes data centres are absent from the Climate Change Committee's CB7 advice despite their significant impact on energy use and emissions, and requests confirmation of dialogue between the government and CCC on this gap ahead of the Committee's February report.

Key findings

  • Data centres are not mentioned in the Climate Change Committee's Seventh Carbon Budget or associated documents, despite being a key area of concern.
  • The Committee received an unsatisfactory answer to a written question about whether the Secretary of State has discussed data centre projections with the CCC.
  • The government's response referenced choosing its own pathway while considering energy security and future energy demand trends, but did not address the specific data centre question.
  • The Committee requires information on whether data centre emissions have been accounted for in government planning and what projections and mitigations are in place.

Notable line

One of the reasons I asked this question is because there is no mention of data centres in the CCC's CB7 and its associated documents.
