Green Party urges UK to halt datacenter boom over resource concerns

The Green Party of England and Wales is urging the UK government to end the blanket designation of datacenters as critical national infrastructure (CNI). The party is calling for an immediate pause on new construction until the government establishes strict environmental standards for energy and water consumption.

According to the Green Party, the current CNI status—granted by the UK government in 2024—allows server farms to be prioritized over residential households for essential resources during periods of shortage. Zack Polanski, leader of the Green Party, stated that the government is currently waving through the "rampant building of new datacenters," which he argues could drive up energy bills and leave local communities vulnerable to water shortages.

The pressure on infrastructure

This push for a moratorium comes amid a construction boom in the sector, with a heavy concentration of new sites in the South East and London. These regions are already identified as water-stressed, leading to concerns that the rapid expansion is unsustainable. The strain on the electrical grid has already had tangible local effects; in parts of West London, housing developments have been paused due to power constraints linked to datacenter demand.

Further complicating the issue are warnings that official water forecasts for England have excluded the demand generated by these facilities. This gap in planning suggests that the true impact of the datacenter boom on the national water supply may be significantly underestimated by policymakers.

The AI superpower trade-off

The conflict underscores a growing tension between the UK's strategic ambition to become a global AI superpower and the immediate social and environmental costs of that goal. While the Green Party views the current trajectory as a risk to public utilities, the government maintains that such a pause would be counterproductive.

A government spokesperson argued that halting construction would simply drive investment and high-quality jobs abroad. Furthermore, the government suggests that reducing domestic capacity would leave Britain dangerously dependent on overseas computing for the processing of sensitive defense and health data.

What remains unresolved

As the debate intensifies, the primary point of contention remains the CNI designation. If datacenters retain priority access to utilities, critics argue it will exacerbate shortages for millions of citizens. However, the government has yet to signal a willingness to revise the 2024 designation or introduce the specific environmental mandates requested by the Green Party. Observers will be watching for whether the government introduces new transparency requirements for water and energy reporting to address the planning gaps in the South East.
