## Summary

The UK government’s new policy for AI data centres may undermine its net zero targets by permitting onsite gas-fired power generation while developers wait for grid connections. Four hyperscale data centres—including three in southern England—are reportedly planning to use gas, potentially emitting **4.1 million tonnes of CO₂ annually**, more than the combined emissions of Manchester, Liverpool, and Southampton. Critics, like Labour MP Toby Perkins, warn that increased gas use contradicts climate commitments, while developers argue grid delays force temporary fossil fuel reliance.

The government insists data centres are essential for the economy and economy, citing the **72 gigawatts** of pending demand—double the UK’s 2025 peak electricity usage of **45 gigawatts**. A **British Data Centre Covenant** requires developers to fund local communities and protect water supplies but allows onsite power generation as a last resort. Critics, including environmental groups and local councillors, argue this sets a dangerous precedent, risking net zero progress and local pollution. Developers claim they are exploring renewable alternatives but cite feasibility challenges.

## Key points

- Four UK data centres may use gas power, emitting **4.1M tonnes CO₂/year**—more than three cities combined
- Government permits onsite gas generation due to **72GW demand** vs. **45GW grid capacity**
- Developers say grid delays force temporary fossil fuel reliance; critics call it a net zero risk

## Why it matters

Gas-powered data centres could reverse UK climate progress while AI demand strains the grid, forcing trade-offs between economic growth and emissions targets.
