Thousands of demonstrators assembled in Edinburgh to voice opposition to large-scale artificial intelligence data centre development, marching down the Royal Mile towards the Scottish Parliament. According to BBC News, the event reflects growing concern about the environmental and social consequences of data centre construction across Scotland and Europe.
Participants carried placards with messages including "AI data centres threaten humanity" and "AI data centres: costing the Earth", while some wore distinctive costumes to highlight specific concerns. Herald Scotland reported that more than 80 organisations and groups participated in the march, encompassing community campaigners, climate groups, trade unions, artists and anti-poverty charities.
The protest coincides with a broader wave of opposition across Europe, with more than 70 demonstrations against AI data centres occurring in 15 countries this month. The march also aligned with global climate action surrounding the UN climate talks, COP31, in Antalya, Turkey.
Many attendees represented communities directly affected by proposed developments. Residents from Cockenzie in East Lothian, Larbert in Falkirk, and other areas marched to oppose specific projects in their localities. The National reported that Chapelcross campaign organiser Kim Cairns expressed concern about the proposal's effects on her children and community, while protesters called on First Minister John Swinney to "step up or step aside" on the issue.
Demonstrators demanded a nationwide public consultation and a "national conversation" before major data-centre developments receive approval. The Scottish Greens and campaign groups have called for a moratorium on large data centres, arguing they could undermine climate targets and place additional pressure on renewable energy supplies.
What are the scale differences between existing and planned facilities?
Scotland's data centre landscape is set to change dramatically if planned projects proceed. The largest existing facility is DataVita's site in Airdrie, North Lanarkshire, with a capacity of 12 megawatts. However, a proposed data centre at Chapelcross in Dumfries and Galloway would have a capacity of 1,000 megawatts, making it one of the largest in the world. A 213 megawatt proposed data centre at South Gyle was called in by the Scottish Government for appeal after councillors initially refused planning permission.
Concerns about these developments centre on their physical footprint, potential noise, visual impact, and resource consumption. People living near proposed sites have expressed worries about water usage, electricity demand, and landscape changes.
What is the government's position on data centre regulation?
Innovation Minister Alyn Smith characterised data centres as "the whisky bonds of the AI sector", suggesting they represent a significant economic opportunity for Scotland. However, he acknowledged that public discourse around the subject had become "wild", arguing that comparisons to problematic facilities elsewhere did not reflect Scotland's regulatory approach.
"You'd think there wasn't a planning system at all. Comparing a really bad data centre in the middle of the Utah desert doesn't track through to what we're going to have in Scotland."
The Scottish Government has implemented new oversight measures. Planning authorities are now required to notify ministers of new data centre applications, and a planning direction mandates an Environmental Impact Assessment for all new data centres with a power capacity exceeding 50 megawatts.
The government confirmed it is developing a strategic approach to maximising the public benefit from data centres located in Scotland. Earlier this month, Smith attended a meeting in Edinburgh where businesses discussed the challenges and benefits of adopting AI, and participants explored the role of Scotland's universities and colleges in developing AI and data skills to benefit the economy.
What regulatory changes are coming?
The Scottish Government will publish new planning guidance on data centres before the end of 2026. A Scottish Government information release dated 3 November indicated that formal planning guidance for hyperscale data-centre applications had not yet been issued to planning authorities, though the government stated that guidance work remained under active consideration.
These regulatory developments come as Scotland faces a planning battle over 23 proposed AI data centres. Supporters cite investment and job creation benefits, while opponents worry about energy use, water consumption, and landscape impact. The expansion of AI data centres in Scotland could raise household electricity bills and delay climate goals, according to warnings previously issued to Members of the Scottish Parliament.
