Holyrood has voted to pause planning applications for all new AI datacentres for up to a year until the Scottish government has developed a national strategy for the rapidly expanding industry. On Wednesday, MSPs backed a Scottish Labour motion to halt new schemes for up to 12 months while rules on hyperscale datacentres are developed, in what could be a blow to the British government's AI strategy. ## A Boom That Outpaced the Rules Scotland has seen a boom in planning applications for large datacentres as global investment in AI infrastructure has exploded, with British officials encouraging developers to include Scotland in the buildout. Datacentres are critical for storing and processing the data used by AI systems. One scheme in Auchtertool, Fife, has been billed as the second largest in the world and is among more than 20 large datacentres proposed in Scotland so far. Campaigners have raised concerns about water usage and carbon emissions from large datacentres, and questioned whether Scotland has the capacity to cope with the resulting explosion in energy demand. The concerns are not hypothetical: every hyperscale facility draws grid power around the clock, consumes water for cooling, and occupies land that communities argue should face the same scrutiny as any other heavy infrastructure. Under Wednesday's vote, only projects that meet robust environmental impact assessments considering the impact on neighbouring communities will be approved, and no decisions will be made on planning applications for up to a year until national planning guidance has been formalised by the Scottish government. The motion passed with cross-party support, placing the issue firmly on the Scottish government's legislative agenda for the year ahead. ## Campaigners Hail a Landmark Day Kat Jones, the director of the NGO Action to Protect Rural Scotland, who has spearheaded demands for a datacentre moratorium in Scotland, called the vote a "landmark day for all those communities across Scotland who have been extremely concerned about projects coming forward in their areas." "There's much still to be done, but this is a huge step forward and we can all at least take a breath now," she said. "That means the Scottish government must now urgently call in those applications which are approaching a decision date. The communities will expect nothing less." This month, hundreds of people from community groups protested outside Holyrood against the construction of large datacentres for AI until clear planning rules and a definition of a "green" datacentre had been formalised. The protest was the most visible sign of a campaign that has grown alongside the pipeline of proposals, from the central belt to the north east. Ahead of the vote, the Scottish government announced that large-scale datacentres would face mandatory environmental impact assessments, responding to growing concern about the ecological impact of the AI boom. The assessment requirement applies regardless of the moratorium's duration, meaning any scheme that eventually proceeds will carry documented analysis of its water, carbon and community effects. ## Politicians Split on the Economic Trade-Off After the vote, Scottish Labour's economy spokesperson, Daniel Johnson, said the economic potential of the AI boom needed to be weighed alongside the impacts on the environment, communities and energy demand. "So far the SNP has failed to do the work needed to get this right — that must change," he said. "It is right that the SNP government has accepted the need for national guidance before more decisions are made, and I want to see that guidance delivered with the urgency needed." "The SNP must put in place the protections needed and ensure that any datacentres work for communities, create good jobs and deliver for Scotland," Johnson added. The Scottish government has been contacted for comment on the motion it now must translate into planning guidance. Officials had previously encouraged the buildout, reflecting British government pressure to secure AI capacity within the UK. ## What Happens Next The freeze means applications already in the system — including the massive Fife proposal — face delay while national planning guidance is drafted, and any project advancing before then must clear the stricter environmental assessment bar. The vote came ahead of a summit at Dumfries House in Ayrshire on Thursday, where AI leaders are due to gather with King Charles to discuss the future of the technology, amid warnings from some in the industry that the speed of its development poses risks. For Scotland's communities, the moratorium converts a year of protest into formal political process: guidance first, decisions later. The standoff in Scotland mirrors a debate playing out across Europe, where governments are courting AI datacentre investment while grappling with the electricity, water and land demands that hyperscale facilities bring. How Edinburgh drafts its national guidance — and whether it defines what counts as a green datacentre — will determine how much of the global AI infrastructure boom ultimately reaches Scottish soil, and on what terms.
