Scotland’s ‘green datacentres’ policy ignores emissions impact of AI, analysis shows

Scotland’s policy promoting “green datacentres” to attract AI investment faces criticism for overlooking the significant carbon emissions associated with these facilities, according to an analysis by the charity Action to Protect Rural Scotland (APRS). The policy, established in 2022 before the rise of AI technologies like ChatGPT, lacks a clear definition of what constitutes a “green datacentre.” This ambiguity allows datacentres with substantial emissions to be labeled as environmentally friendly, potentially misleading policymakers and the public. More than a dozen datacentres are currently seeking planning permission in Scotland, including a major AI growth zone in Lanarkshire backed by £8.2 billion in private investment. These datacentres collectively could consume about 6.2 gigawatts of power, exceeding Scotland’s peak winter electricity demand by 50 percent. The UK’s National Energy System Operator has encouraged datacentre developers to locate in Scotland due to its higher share of renewable energy and fewer grid constraints. However, APRS warns that the lack of transparency around the energy demands and emissions of these facilities risks undermining Scotland’s climate goals. For example, a datacentre in Edinburgh claimed to be “green” despite plans to use 200 diesel backup generators, which APRS equates to the pollution of 100,000 idling cars. Green MSP Ariane Burgess has called for urgent clarity on the definition of “green datacentres” and how their energy consumption will be managed. Local planning authorities appear to be accepting datacentres’ self-assessments without robust criteria, as highlighted by the National Planning Framework 4, which references green datacentres but does not provide a concrete emissions standard. The growing datacentre sector poses a challenge to Scotland’s ambition to reduce greenhouse gas emissions, especially as new facilities could significantly increase electricity demand across Great Britain. The situation underscores the tension between economic development ambitions tied to AI and digital infrastructure and the urgent need to meet climate commitments. Without stricter definitions and regulatory oversight, Scotland risks endorsing datacentres that contribute heavily to carbon emissions while branding them as sustainable investments. This could complicate efforts to balance technological growth with environmental responsibility in the coming decade.
