Environmental groups, local communities, and digital rights campaigners across Europe organized major demonstrations for November 6 and 7, 2026, against the rapid expansion of large data centres used for artificial intelligence (AI) and cloud services. UK campaigners have joined the coordinated actions, raising concerns about electricity demand, water use, land development, and whether local communities have enough influence over new projects.
The demonstrations are part of the Stop Dirty Data Centres campaign. Organizers say more than 100 groups from 15 European countries are involved, with over 70 actions scheduled throughout November. These activities include public demonstrations, marches, community meetings, and awareness events calling for stricter oversight of large data centre projects.
The movement includes campaigners from the UK, Ireland, Germany, France, Spain, Denmark, Finland, Poland, Italy, and the Netherlands. Activities across the campaign include a march in Dublin, a gathering outside Poland’s parliament in Warsaw, and local events in Bristol, Berlin, and other European cities. Some participants are opposing specific construction proposals, while others want governments to introduce stronger rules for large data centre developments.
In the United Kingdom, environmental organizations and community groups have organized events in London, Bristol, and Devon. A further demonstration is planned for November 14 in Edinburgh, Scotland, with a coalition of approximately 75 organizations supporting the march. According to Friends of the Earth Scotland, participants are expected to gather at the top of the Royal Mile at 11:30 a.m. before marching toward the Scottish Parliament at noon. Protesters are calling for a national public consultation on major AI data centre proposals.
Technology companies are expanding computing infrastructure to meet growing demand for AI tools and cloud services. Data centres house servers that run AI models, store information, and support online applications. Not every data centre is built only for AI, but the growth of AI workloads is increasing demand for powerful computer chips, electricity, and cooling equipment.
However, campaigners argue that large data centres can place pressure on local electricity networks and water supplies. The International Energy Agency estimates that data centres worldwide used approximately 485 terawatt-hours of electricity in 2025 and could consume around 950 terawatt-hours by 2030. Some facilities also use water-based cooling systems, although water consumption varies depending on the technology, climate, and location. These global electricity figures do not establish the environmental impact of any individual European project.
Another major concern is the amount of land required for large data centre projects. Residents in several European communities have questioned plans to build these facilities near homes, farmland, and environmentally sensitive areas. Campaigners believe local people should have more influence over decisions that could affect their surroundings, energy supplies, and public infrastructure.
The Stop Dirty Data Centres coalition is calling for a moratorium, or temporary halt, on new large-scale data centre construction until environmental and social concerns receive fuller review. Campaigners want clearer planning rules, stronger environmental protections, and greater public involvement in major infrastructure decisions. In the United Kingdom, however, the government has previously rejected calls for a nationwide pause on AI data centre construction, favoring stronger oversight and planning controls instead.
On November 6, activists from the Dutch group Geef Tegengas entered a data centre construction site associated with Microsoft in Amsterdam, with some protesters climbing a crane and setting off flares. Dutch police said approximately 150 to 200 people were detained on suspicion of trespassing. The Amsterdam site breach was separate from the Stop Dirty Data Centres campaign, whose affiliated demonstrators remained outside the construction site’s fence. The Europe-wide coalition said it had not organized the break-in. Microsoft stated that it respected peaceful demonstrations but did not support unlawful actions or activities that could endanger people’s safety.
European policymakers are also trying to expand computing capacity while making large data centres more transparent and energy-efficient. The European Commission’s energy performance framework requires qualifying data centres to report information about their energy performance. In September 2026, the Commission proposed a common rating scheme intended to make data centre electricity and water use more transparent. These measures aim to improve environmental oversight while the region continues developing its digital infrastructure.
The challenge extends beyond Europe. In the United States, data centre developers are facing an AI data-centre power crunch, with electricity availability affecting how quickly new computing projects can move forward. For European policymakers, the central challenge is to support AI development while addressing local energy demands, water availability, environmental protection, and community concerns.
The demonstrations show that public debate about artificial intelligence now extends beyond software and digital tools. Technology companies are facing questions about electricity consumption, water management, and the effects of large computing facilities on nearby communities. In the United States, OpenAI has announced community-focused data centre pledges covering infrastructure costs, environmental transparency, and public involvement. However, these voluntary commitments are different from the regulatory requirements being considered in Europe.
With further actions planned, including the November 14 march in Edinburgh, the debate over AI data centres is expected to continue beyond this week’s demonstrations. The central questions are whether new facilities can access sufficient electricity and water, how their environmental effects will be measured, and whether nearby communities will have a meaningful say before construction is approved.
