Public opposition to data center construction is spreading from the U.S. to Europe and Asia, creating investment risks as communities push back against projects citing power consumption, water usage, and local environmental concerns.
Europe has faced the most pronounced resistance. More than 70 data center projects were rejected or restricted between January and April, exceeding the total rejections for all of 2025, according to the European Data Center Monitor. Public opposition has affected around $42 billion of data center investments through delays and cancellations, compared to $77 billion in the U.S., STL Partners research found. Scotland paused planning approvals for new hyperscale data centers after campaigners warned against repeating Ireland's experience, where power demand led to a moratorium. Denmark passed emergency legislation that could place data centers at the back of the queue for grid power applications following a surge in applications. Spain proposed rules requiring data centers to source 80% of electricity from renewables, while U.K. projects have stalled after local opposition.
Olivier Darmouni, an associate professor at HEC Paris specializing in energy transition, told CNBC that pushback could be the "straw that breaks the camel's back." He noted that Europe's densely populated countries and higher electricity prices create additional friction, compounded by the fact that many operators are U.S. companies. Data centers are perceived as "giant ghost warehouses that consume a lot of resources" with diffused benefits for AI that fail to convince skeptical locals.
South Korea confronts similar tensions despite its government naming AI data centers as one of three major investment priorities alongside semiconductors and physical AI. In Seoul's Geumcheon district, residents demanded permit revocation for a proposed data center near homes. Protests continued for 172 days as of mid-August. Officials announced plans to require majority resident consent within 200 meters of sites and introduced a three-stage project review system.
Asya Walters, managing director at Alvarez & Marsal, told CNBC that communities now possess real power to derail multibillion-dollar projects. She noted the U.S. business-friendly environment has historically made overcoming pushback easier, but Europe and Asia show "hot and coldness" at the country level, creating challenging investment dynamics. Even failed projects impose costs, as operators spend heavily before permits are secured.
Equinix executive Eulalia Flo stated she does not view opposition as a "structural constraint on growth," but acknowledged "the policy environment is genuinely tightening in some markets." Verne CEO Dominic Ward attributed resistance to newfound visibility, saying data centers moved from unknown infrastructure to recognizable economic drivers, making communities more scrutinous.
