Scotland Mandates Environmental Impact Assessments for Data Centers Above 50 MW

Scotland has introduced a new planning requirement that will compel developers of large data centers to conduct Environmental Impact Assessments (EIAs) as part of the planning permission process, a move that underscores growing regulatory scrutiny of the energy and environmental footprint of the rapidly expanding data center industry.

The new direction, formally titled The Town and Country Planning (Environmental Impact Assessment) (Data Centres exceeding 50MW Power Capacity) (Scotland) Direction 2026, was developed with input from the Scottish Science Advisory Council (SSAC). Under the rule, any new data center development in Scotland with a power capacity exceeding 50 MW must now include an EIA when applying for planning permission.

According to a press release from the Scottish Government, data center proposals falling below the 50 MW threshold are not automatically exempt from EIA requirements. Such facilities remain subject to existing environmental impact assessment regulations, with the need for an assessment determined on a case-by-case basis according to the circumstances of the development and established legislative criteria.

Hannah Mary Goodlad, Public Finance Minister for Scotland, framed the guidance as a proactive measure for a sector still in its formative regulatory stage. "The Scottish Government recognises that data centres are a rapidly evolving sector attracting a broad range of views, opinions and concerns, and that evidence on the environmental impact of data centres continues to develop. As this is an emerging industry, we have the opportunity to get this right from the start. The guidance issued today is the next step in that process," she said.

Goodlad further emphasised the need to reconcile economic ambitions with environmental and community interests. "We must balance the economic and employment interests in developing data centres with national energy, climate and community wealth building ambitions, which are vital to our future prosperity, as well as the potential impact on local communities. Ensuring that an Environmental Impact Assessment is always part of the application process will create a level playing field for developers and will ensure potentially significant environmental effects are considered from the outset."

An EIA assesses the likely significant environmental effects of a proposed development and consolidates those assessments as part of the planning process. The requirement follows a planning direction published by the Scottish Government. Last month, the government also directed planning authorities to notify Scottish Ministers within seven days of validating applications for new data centers, signalling a broader effort to tighten oversight of the sector's expansion.

The new EIA mandate places Scotland among a growing number of jurisdictions seeking to impose stricter environmental standards on data center development. As power-intensive computing facilities continue to proliferate across Europe, regulators are increasingly focused on ensuring that the energy consumption, land use and community impact of these projects are systematically evaluated before approval. For developers, the requirement introduces an additional layer of planning complexity, but also establishes a uniform standard that could reduce uncertainty across the approval process.
