The Greens’ core argument centers on the disproportionate resource consumption of these facilities. Their spokesperson emphasized the need for "basically a moratorium other than local scale data centres for the local community," arguing that the current trajectory is unsustainable. A significant point of contention for the party is the government’s 2024 classification of data centres as "critical infrastructure." While this designation provides extra government support during incidents such as cyber-attacks or extreme weather events, the Greens contend that it creates a perilous precedent. "At a time when three-quarters of the country are in drought, it is outrageous that these are being considered critical infrastructure," Polanski argued, highlighting the public’s perception that "critical infrastructure means hospitals, water, electricity. It doesn’t mean Artificial Intelligence." The Greens fear this classification could lead to data centres receiving priority access to water supplies over households during periods of scarcity, a concern the government has sought to allay by stating that data centres would not automatically be granted priority during shortages.
However, the data centre industry strongly refutes these claims, emphasizing the vital role these facilities play in modern society and disputing the extent of their environmental footprint. Mark Acton, executive director of the Data Centre Alliance, speaking to the Today programme, countered the Greens’ assertions about water usage. He maintained that data centres are not siphoning water from local communities and, surprisingly, use significantly less water than many common recreational facilities, such as leisure centres and golf courses. Acton also highlighted the inherent difficulties in securing planning permission for new data centres, even within designated AI growth zones, underscoring the rigorous regulatory hurdles already in place. Crucially, Acton broadened the public’s understanding of data centres beyond just Artificial Intelligence, stressing their pervasive and indispensable nature. "Data centres are not just AI, data centres run our lives… social media runs through data centres, our banking systems run through data centres," he explained. "We depend on these things massively." This perspective underscores the intricate web of digital services that rely on these facilities, from daily communications to financial transactions, all of which would be severely impacted by a blanket ban.
Further complicating the debate is the revelation that ministers have not conducted a comprehensive environmental assessment on the impact of their "Delivering AI growth zones strategy." This discovery, made by the BBC, raises questions about the government’s foresight and commitment to environmental due diligence in its pursuit of technological advancement. A government official downplayed the oversight, describing the paper as merely "a statement of intent, rather than a formal policy moving towards implementation." Critics, however, argue that even a statement of intent for such a significant strategy should be underpinned by a thorough understanding of its potential ecological consequences.
The lack of transparency surrounding water consumption by data centres in the UK further fuels the Greens’ demands. Currently, there is no mandatory requirement for these facilities to report their water usage. Research conducted by the Water Research Centre consultancy in February provided some insight, estimating that data centres in England collectively consume approximately 1.9 billion litres of drinkable water annually. While this figure represents about 0.2% of the non-household market, the consultancy explicitly warned of a "clear upward trend" in water usage, suggesting that this percentage is likely to increase significantly as demand for data processing continues to surge. Environmental charity Global Action Plan corroborated these concerns, with their research suggesting that individual large-scale data centres could consume as much as 1.5 million litres of water per day – a staggering amount that could put immense pressure on local water resources, especially in drought-prone regions.
In response to these environmental concerns, the Green Party has outlined a series of policy proposals aimed at mitigating the impact of future data centre development. They advocate for new facilities to be constructed exclusively on brownfield sites, thereby avoiding the destruction of green spaces. Furthermore, they propose that these sites be strategically located near renewable energy sources, enabling data centres to operate on clean power whenever feasible, reducing their carbon footprint. To enhance accountability and transparency, the Greens also demand that owners of data centres be legally required to provide annual figures detailing both their water and electricity consumption. This data, they argue, would be crucial for monitoring environmental impact, informing policy decisions, and encouraging more sustainable operational practices within the industry.
The government, however, has issued a robust defence against the proposed ban, portraying it as a severe threat to the UK’s economic prosperity and national security. A government spokesperson firmly stated: "A pause on building new data centres would simply send investment and good jobs abroad, while leaving Britain dependent on overseas computing for the processing of sensitive health and defence data." Such a move, they concluded, "would be a disaster for jobs and national security." While rejecting a blanket ban, the government did clarify that it is not offering "a blank cheque for Big Tech or that every data centre should be approved." Instead, it insists that developers must demonstrate a commitment to sustainability, requiring them to plan for the use of clean power, responsible water management, the creation of British jobs and supply chains, and significant investment in the communities where they are built. The government also sought to shift some of the focus regarding water scarcity, highlighting that a far greater volume of water – roughly a fifth of the total supply – is lost annually through leaks in the existing infrastructure, implying that this issue requires more immediate attention.
Campaign groups have also weighed in on the debate, largely supporting the call for greater accountability and more stringent conditions for data centre development. Rosa Curling, co-executive director of the campaign group Foxglove, acknowledged that "any action to pause or slow down this construction frenzy is positive." However, she asserted that the government and local authorities already possess the necessary powers to impose strict conditions, ensuring that "tech billionaires, not the British public, pay for their costs in full." Curling went further, proposing a minimum standard: "As a minimum, no hyperscale data centre should be given the go-ahead unless the developer also builds new renewable energy and storage to power it completely – and commits to not draining local water supplies."
This escalating debate encapsulates a broader global challenge: how to reconcile rapid technological advancement, particularly in areas like Artificial Intelligence, with pressing environmental concerns. The UK finds itself at a crossroads, balancing the economic benefits and strategic necessity of a robust digital infrastructure against the imperative to protect finite natural resources and achieve ambitious climate goals. The Greens’ call for a temporary ban serves as a powerful catalyst, forcing a critical examination of the true cost of our digital future and demanding a more sustainable and transparent approach to data centre development. The outcome of this discussion will likely shape not only the UK’s technological landscape but also its environmental legacy for decades to come.
