calling a datacentre 'green' while burning gas to power it
Scotland is courting artificial intelligence investment with a policy framework that has not kept pace with the technology it seeks to attract. The government's promise that 'green datacentres' will leave climate targets unharmed rests on analysis completed before the AI era began, and no official definition of 'green' has ever been written into planning law. As a dozen facilities seek approval to draw power equivalent to one and a half times Scotland's peak winter demand, the gap between ambition and accountability grows harder to ignore.
- Scotland's 'green datacentre' label is being applied to facilities that include hundreds of diesel generators, because no law or planning document actually defines what the term means.
- A cluster of pending projects would collectively demand 6.2 gigawatts — reshaping the country's entire energy landscape, not merely adding to it.
- Over 100 datacentre projects have already requested gas network connections, revealing that the electricity grid cannot absorb this demand and that fossil fuels are quietly filling the gap.
- The emissions analysis underpinning Scotland's planning framework was written in 2022, before ChatGPT existed, and has never been updated to account for the voracious energy appetite of modern AI.
- Green MSPs and civil society groups are demanding transparency, but the Scottish government continues to emphasise investment opportunity while leaving the critical definitions unwritten.
Scotland is pursuing artificial intelligence investment with considerable enthusiasm, but the policy meant to keep that pursuit honest is built on foundations that have quietly crumbled. The government has never formally defined what a 'green datacentre' is, and the analysis assuring the public that these facilities won't damage net-zero targets was completed in 2022 — before the AI boom changed everything about how much electricity these buildings actually consume.
More than a dozen datacentres are currently moving through Scotland's planning system. Together, they would draw roughly 6.2 gigawatts of power — one and a half times the country's entire peak winter electricity use. One proposed AI growth zone near Glasgow is backed by £8.2 billion in private investment. The scale is not incremental; it is transformational.
Action to Protect Rural Scotland, an Edinburgh-based charity, investigated how these approvals are being granted. Their findings were stark. Developers are self-applying the 'green' label, and local authorities are accepting it, even though Scotland's National Planning Framework contains no definition of what that label requires. One Edinburgh facility submitted plans featuring 200 diesel backup generators — the emissions equivalent of 100,000 idling cars — and was still approved as a green project. The planning committee itself acknowledged, in its own paperwork, that no definition existed.
The framework's assurance of 'negligible impact' on greenhouse gas targets was written when researchers believed datacentre emissions would be offset by reduced travel. Nobody was modelling the energy cost of large language models. That analysis has never been revisited. Meanwhile, energy companies have disclosed that more than 100 datacentre projects have requested gas network connections, because grid capacity is already strained and connection queues stretch for years. Officials have acknowledged this raises 'an interesting question' for UK climate goals — a notably measured response to what amounts to a structural contradiction.
Ariane Burgess, a Green MSP, has pressed the government for clarity and received little. Kat Jones of APRS described it as 'pretty shocking' that the carbon footprint of hyperscale datacentres had been entirely excluded from the planning framework's emissions analysis. Scotland wants the investment and the jobs that come with it. But without a definition of 'green,' without updated science, and with fossil fuel connections already being sought at scale, the framework functions less as a guardrail than as a permission slip.
Scotland is chasing artificial intelligence investment with open arms, but the policy framework meant to keep that ambition aligned with climate goals is built on assumptions that no longer hold. The problem is both simple and consequential: the government has never clearly defined what a "green datacentre" actually is, and the analysis underpinning the promise that these facilities won't harm Scotland's net-zero targets was completed in 2022, before ChatGPT existed and before anyone fully grasped how much electricity AI systems would demand.
Right now, more than a dozen datacentres are working through the planning process in Scotland. One proposed AI growth zone near Glasgow claims backing from £8.2 billion in private investment. Taken together, these facilities would consume roughly 6.2 gigawatts of power—one and a half times Scotland's entire peak winter electricity use. That's not a minor addition to the grid. That's a fundamental reshaping of the country's energy demand.
Action to Protect Rural Scotland, an Edinburgh-based charity, has been digging into how this is being permitted. What they found is troubling: developers are calling their projects "green datacentres" and local authorities are accepting that label, even though Scotland's National Planning Framework—the document that's supposed to guide these decisions—contains no actual definition of what makes a datacentre green. One Edinburgh facility submitted plans that included 200 diesel backup generators, equivalent to the emissions of 100,000 idling cars, yet still presented itself as a green project. The planning committee approved it while acknowledging, in its own documents, that no definition of "green datacentres" existed in the underlying policy.
The framework itself says these facilities will have an "overall negligible impact" on Scotland's greenhouse gas reduction targets. But that conclusion rests on analysis from 2022, before the AI explosion. Back then, researchers thought any emissions increase from datacentres would be offset by people travelling less. No one was accounting for the energy footprint of training and running large language models. The analysis has never been updated.
Ariane Burgess, a Green MSP representing Highlands and Islands, has been pressing the Scottish government for clarity. "We urgently need transparency around what constitutes a 'green datacentre' and how their huge energy demands will be accommodated by our grid infrastructure," she said. The government, she noted, hasn't provided answers. Last week, energy companies revealed that more than 100 datacentre projects have requested connections to the gas network. They're planning to burn natural gas to power themselves because the electricity grid is already strained and connection times stretch for years. That's a direct contradiction to Scotland's net-zero ambitions, and officials have acknowledged it raises "an interesting question" for UK climate goals.
Kat Jones, director of APRS, put it bluntly: "It is pretty shocking to find out that the vast carbon footprint of hyperscale datacentres has been completely excluded from the greenhouse gas analysis for our planning framework." The Scottish government's response emphasizes the country's renewable energy abundance and skilled workforce, and says it aims to secure investment while aligning with net-zero goals. But without a clear definition of what "green" means, without updated emissions analysis, and with over 100 projects already seeking gas connections, the framework appears to be a permission slip rather than a guardrail. Scotland wants the investment and the jobs. The question is whether it's willing to count the actual cost.

Why does the definition matter so much? Can't a datacentre just be judged on its actual emissions?
Because once something is labeled "green," it gets treated differently by planning committees. It becomes aligned with policy goals. Without a definition, developers can claim the label and local authorities have no grounds to challenge them.
But surely the grid constraints would stop them anyway. You can't build something that uses more power than exists.
That's the trap. The grid is strained, so they're requesting gas connections instead. They're not waiting for renewable capacity. They're burning fossil fuels to power AI systems that are being marketed as green.
How old is the analysis that says this is all fine?
2022. Before ChatGPT. Before anyone understood the scale of energy demand AI would create. It's been four years and no one's updated it.
What would a real definition of "green datacentre" look like?
That's the question no one's answering. You'd need to specify renewable energy percentage, emissions limits, grid impact assessments, backup power sources. Right now there's nothing.
Is Scotland unique in this problem?
The UK government is actively encouraging datacentres to build in Scotland because of the renewable energy. But the policy framework hasn't caught up to what's actually being built.
What happens if this continues unchanged?
Scotland meets its climate targets on paper while burning gas to power AI systems it's classified as green. The investment comes, the jobs come, but the emissions are hidden in a policy gap.
