Summary

• More than 100 groups across 15 European countries are supporting coordinated action scheduled for 6–7 November.
• Organisers are demanding a moratorium on large data centre developments, citing electricity demand, water use, planning, and local impacts.
• The European Commission is separately consulting on minimum energy performance standards, with proposals expected in 2027.

More than 100 organisations across 15 European countries are coordinating protests against large data centre developments, bringing disputes over energy demand, water consumption, and local planning into a broader challenge to Europe’s expanding artificial intelligence infrastructure.

The Stop Dirty Data Centres campaign is organising demonstrations and community events on 6 and 7 November, with activities planned in Ireland, Poland, Denmark, Finland, Spain, the Netherlands, France, the United Kingdom, and other participating countries. Its supporters are calling for an immediate moratorium on major developments while governments examine their environmental and social consequences.

Planned actions include a demonstration outside Poland’s parliament in Warsaw, a march in Dublin, an event near a Microsoft data centre in Denmark, and a public discussion close to a proposed development in Amsterdam. Campaigners in London are also organising activities addressing the concentration of computing infrastructure and its relationship with surrounding communities.

The coalition brings together environmental campaigners, digital rights organisations, and residents concerned about individual development proposals. Its demands vary between locations, although the coordinated programme signals an effort to influence European infrastructure policy rather than pursue separate objections through local planning systems alone.

Local infrastructure carries wider costs

Data centre development has accelerated as cloud providers and AI companies seek more computing capacity. Facilities supporting advanced processors can require substantial electricity connections, cooling equipment, and additional network infrastructure, with the demands of individual projects depending on their size, operating conditions, and technology.

Those requirements can create conflict where electricity networks already face competing demands from housing, industrial development, transport electrification, and other users. A proposed data centre may provide substantial investment, but its ability to connect within the required timetable depends partly on the availability of network capacity and any reinforcement work needed.

Campaigners argue that the effects of these decisions extend beyond the developers purchasing electricity. Local authorities must consider land use, construction activity, noise, water availability, and the potential costs of infrastructure upgrades, while also weighing the employment and investment associated with proposed facilities.

The circumstances differ considerably between sites. Some operators use cooling systems that consume relatively little water during normal operation, while others rely on arrangements whose requirements change with local temperatures and operating loads. It would therefore be misleading to assume that every proposed facility has the same environmental impact.

Electricity demand also needs to be considered alongside its source and timing. A facility operating with low-carbon electricity can have a different emissions profile from one supplied by a more carbon-intensive system, while additional demand may still require network investment or affect the timing of other connections.

Developers sometimes propose reusing waste heat from computing equipment for neighbouring buildings. Such arrangements can improve overall energy utilisation, although their effectiveness depends on nearby demand, the temperature of the available heat, distribution infrastructure, and the commercial terms required to make a project viable.

European regulation is already developing

The European Commission is preparing further requirements for the energy performance of data centres under the Energy Efficiency Directive. Existing measures provide for reporting on energy and environmental indicators, while a European database and rating arrangements are intended to make performance more transparent and comparable.

In September 2026, the Commission launched a consultation on minimum energy performance standards, with submissions accepted until 14 December. The results will inform a legislative proposal expected in the second quarter of 2027.

The consultation reflects the EU’s attempt to reconcile additional computing capacity with energy efficiency, environmental protection, and electricity system planning. Brussels regards digital infrastructure as important to European competitiveness and technological sovereignty, but acknowledges the pressure that rapid development can place on electricity grids and other resources.

Efficiency standards and construction restrictions address different questions. Requiring a facility to use less electricity for a given amount of computing work may improve its performance without reducing total consumption if the quantity of computing carried out increases more rapidly.

A moratorium would instead restrict new development while the relevant environmental and planning requirements are considered. Campaigners see a pause as a way to prevent projects from advancing before public authorities have established what level of development is appropriate and who should bear its associated costs.

The Commission’s consultation does not propose the same measure as the campaign, and no Europe-wide construction moratorium has been adopted. National and local authorities continue to apply their own planning, energy, and environmental rules to individual projects.

Investment ambitions meet public opposition

Data centres have become central to European plans for AI computing capacity, particularly as policymakers seek alternatives to dependence on infrastructure concentrated outside the region. New facilities can support domestic research, software businesses, and wider digital services, although their economic contribution depends on the activity they enable rather than construction expenditure alone.

For operators and investors, opposition introduces another consideration alongside electricity availability, financing, equipment procurement, and planning approval. Projects may face delays or additional requirements where local authorities seek more evidence about their environmental effects and infrastructure needs.

The question of who pays for electricity network reinforcement can be particularly contentious. Connection charges and broader network costs are determined through national regulatory arrangements, making the distribution of expenditure more complicated than a direct comparison between a developer’s electricity bill and the demands of nearby households.

Permanent employment is another factor in local assessments. Large data centres can support construction and specialist technical jobs, but their operating workforces may be relatively small compared with those associated with some other forms of industrial development using comparable land or electricity capacity.

Communities are consequently asking how proposed facilities will contribute to local economies and whether promised benefits can be demonstrated. The answers depend on individual project characteristics, including location, operational arrangements, commercial commitments, and the availability of supporting infrastructure.

The planned demonstrations do not establish that European governments will accept the campaign’s demands, nor do the number of supporting organisations and countries indicate the eventual attendance at individual events. They do show that opposition to data centre development is becoming more coordinated across national boundaries.

With the Commission’s consultation running until December and further European computing investment under consideration, the terms on which new data centres secure electricity, land, and local approval will remain subject to scrutiny beyond the two days of protest.
