Datacentre developers face calls to disclose effect on UK’s net emissions

Why it matters: The unchecked expansion of AI-driven datacentres poses an immediate and critical threat to the UK's net-zero targets and energy grid stability, potentially forcing a choice between technological advancement and environmental commitments.
- Campaign groups (Foxglove, Friends of the Earth, and five others) are demanding datacentre developers prove their projects won't increase UK CO2 emissions or local water scarcity, warning that vast electricity use will generate significant climate emissions.
- Ofgem, the energy regulator, calculates that approximately 140 proposed datacentre schemes, driven by AI, could require 50GW of electricity—exceeding Great Britain's current peak demand by 5GW.
- MPs on the environmental audit committee have launched an inquiry into datacentre sustainability, acknowledging the energy secretary's uncertainty regarding future energy demand, despite the UK's 2050 net-zero commitment.
- Planned datacentres in Elsham and Cambois will each demand 1GW of electricity, equivalent to a nuclear power station, necessitating new renewable energy output to avoid increasing emissions.
- A proposed Google datacentre in Essex is projected to emit over half a million tonnes of CO2 annually, underscoring the significant environmental footprint of individual projects.
A looming datacentre boom, fueled by AI, threatens to double the UK's electricity demand, sparking urgent calls for developers to disclose and mitigate their projects' net carbon emissions and water usage. Campaign groups and MPs are pressuring the government to integrate these requirements into national policy, while the energy regulator warns of unprecedented power needs that could exceed current national peaks.
