Call for Moratorium on New Facilities Amid Resource Concerns
The Green Party of England and Wales has called for an immediate halt to the approval of new data centres across England. Party leader Zack Polanski has urged the government to implement a temporary freeze, citing deep concerns over the massive volumes of water and electricity required to power and cool these facilities, particularly as artificial intelligence (AI) technology continues its rapid expansion.
Polanski argued that the rapid growth of the sector necessitates far more stringent environmental regulations. He has also championed giving local communities a greater voice in deciding whether these large-scale industrial computing hubs should be constructed in their residential areas, ensuring local ecological impacts are fully scrutinized before any construction begins.
The Environmental Toll of Digital Infrastructure
Data centres rely heavily on water to prevent their complex electrical hardware from overheating. However, the exact scale of this consumption remains obscured due to a lack of official regulatory monitoring. Currently, data centre operators in the United Kingdom are under no legal obligation to publicly report their annual water usage. This regulatory gap has left environmental analysts and policymakers relying on independent estimates to gauge the industry’s ecological footprint.
Independent assessments suggest a substantial and growing demand on the nation’s water infrastructure. In February, the Water Research Centre estimated that data centres in England consume approximately 1.9 billion litres of high-quality drinking water each year. While this accounts for roughly 0.2% of the country’s non-household water market, researchers noted a clear and steady upward trend in consumption. Furthermore, research compiled by the environmental charity Global Action Plan indicates that a single large-scale data centre can consume up to 1.5 million litres of water every day.
Clustering in Drought-Affected Regions
The debate is intensified by the geographic concentration of these facilities. There are currently hundreds of data centres operating across the UK, with industry records indicating approximately 477 operational sites as of last year, and many more currently in the planning stages. The vast majority of these facilities are clustered in London and the surrounding counties in the south of England. This regional concentration is highly controversial, as these southern areas are officially experiencing drought conditions.
The environmental strain is compounded by local climate dynamics. Because warmer weather increases the thermal load on server systems, data centres operating in hotter regions require significantly more water to keep their equipment cool, further exacerbating the strain on already depleted local water reserves during summer months.
Debate Over ‘Critical Infrastructure’ Status
Speaking during a visit to a proposed data centre development site in East London, Polanski expressed strong opposition to the ongoing expansion. He described the facilities as resource-intensive operations that threaten local environmental stability, calling for a halt to all developments except for small, local-scale projects designed specifically to serve immediate community needs.
Polanski also criticized the government’s decision to classify data centres as critical national infrastructure in 2024. This designation grants the facilities priority government support and protection during emergencies, such as extreme weather events or cyberattacks. Polanski argued that classifying AI data processing alongside life-sustaining services like hospitals, clean water, and electricity is a misallocation of resources. The Green Party raised concerns that this classification could allow commercial data centres to take priority over residential households for water access during severe shortages. However, government officials have disputed this claim, stating that data centres would not automatically receive priority over domestic users during water crises.
Missing Environmental Strategy Assessments
The controversy surrounding the rapid expansion of digital infrastructure has been further heightened by revelations regarding the government’s policy framework. It has emerged that ministers did not perform a formal environmental impact assessment before introducing their strategy document, titled ‘Delivering AI growth zones’. Government representatives defended this omission by clarifying that the document is currently treated as an initial statement of intent rather than an active, formal policy undergoing implementation.
Government Warns of Economic and Security Risks
The UK government has strongly rejected the Green Party’s call for a temporary ban, warning that a moratorium would have severe national consequences. A government spokesperson cautioned that halting new developments would immediately drive international investment and highly skilled jobs out of the country. Furthermore, ministers warned that a freeze would compromise national security. Without domestic data storage and processing facilities, the UK would become dependent on foreign computing infrastructure to handle sensitive national data, including defense intelligence and public health records. A spokesperson characterized a development freeze as a potential disaster for both British employment and national defense.
In response to environmental concerns, the government pointed to broader issues within the national utility network, noting that approximately one-fifth of the country’s water supply is currently lost through infrastructure leaks. However, officials stressed that rejecting a ban does not mean giving technology giants unchecked freedom to build. Ministers insisted that developers must present responsible plans that incorporate clean energy sources, practice sustainable water management, establish domestic jobs and supply chains, and deliver tangible financial investments to the local communities where they build.
Proposing a Sustainable Path Forward
The Green Party has outlined a series of alternative guidelines to manage the digital transition more sustainably if development eventually resumes. The party recommends that future data centres be restricted to brownfield sites rather than green spaces, and positioned close to renewable energy generation hubs to facilitate the direct use of clean power. Additionally, the Greens are calling for legally binding requirements for facility operators to submit comprehensive annual disclosures detailing their exact water and electricity consumption, ensuring greater public accountability in the face of ongoing climate challenges.
