Thousands of people have joined a protest in Edinburgh against the building of large-scale AI data centres.
Demonstrators carrying placards — some in costume — assembled at the top of the Royal Mile before marching towards the Scottish Parliament.
Why this is a different kind of story
We have covered data-centre opposition twice this month: North Ockendon in east London, where residents object to a campus on green belt land, and Cardiff, where the Welsh government took a decision away from the city council.
Both were single applications, argued in planning terms by the people who live nearest. A march of thousands through a capital city is not that. It is the point at which objection stops being site-specific and becomes a political position about the technology itself — and governments respond to the two very differently.
What the placards said
Protesters carried slogans including "AI data centres threaten humanity" and "AI data centres: costing the Earth".
Some attended to oppose plans in particular communities — including Cockenzie in East Lothian and Larbert in Falkirk — so the march combined both kinds of objection: the general and the local, in the same crowd.
The event is part of a wave of protests across Europe, and comes amid widespread debate about the environmental impact of data centres.
The timing is not accidental
The Scottish government will soon publish new planning guidance on data centres, and said it is developing a strategy to maximise the "public benefit".
A march immediately before guidance is published is aimed at the guidance. That is ordinary politics, and it is usually effective at the margin: the text was drafted before the march, but the thresholds and the conditions within it are exactly the parts that get revisited when a minister has just watched thousands of people walk to the parliament.
The phrase the protesters are answering
Innovation Minister Alyn Smith recently described data centres as "the whisky bonds of the AI sector".
It is a deliberately Scottish framing — a whisky bond is a warehouse where something valuable matures, generating local employment and national export revenue from a building most people never enter. The protesters clearly reject the comparison, and the strongest counter-argument is in the detail of the analogy itself: a bonded warehouse does not consume electricity and water at the scale of a hyperscale campus.
What Bangladesh should take from it
Bangladesh is courting this investment while the countries that already have it are arguing in the street about whether it was worth it. That is not a reason to refuse it — the jobs and the digital capacity are real. It is a reason to settle the conditions now, while an application is still a proposal: how much power, drawn from where, how much water, and what happens if the grid cannot carry it. Those terms are nearly impossible to add once a campus is built, and Edinburgh is what it looks like when people conclude they were never offered the choice.
One thing the march does not settle
A protest establishes that opposition is broad. It does not establish what the objectors want instead, and on this subject that gap is real. "AI data centres threaten humanity" and "do not build this one at Cockenzie" are different demands, and a government can satisfy the second while ignoring the first. Whether the guidance that follows is read as a win will depend on which of those two the organisers decide they were marching for.
