Public opposition to data center construction is spreading from the U.S. to Europe and Asia, creating investment delays and raising costs for operators as communities push back against projects near residential areas.
STL Partners research found that public opposition has affected around $42 billion of data center investments in Europe through delays and cancellations, compared to $77 billion in the U.S. More than 70 data center projects in Europe faced rejection or restriction between January and April alone, exceeding the total rejections for all of 2025, according to the European Data Center Monitor.
Concerns center on water usage, power consumption, electricity prices, and land requirements. Olivier Darmouni, associate professor at HEC Paris specializing in energy transition, told CNBC the pushback could be the "straw that breaks the camel's back." He noted that AI's benefits are "very diffused" while local harms concentrate in specific communities, which he describes as "giant ghost warehouses that consume a lot of resources and can hurt local communities in some ways."
Scotland paused new hyperscale data center approvals after campaigners warned against following Ireland's path, where power demand triggered a moratorium. Denmark passed emergency legislation that could place data centers at the back of the queue for grid power. Spain proposed rules requiring data centers to source 80 percent of electricity from renewables. U.K. projects stalled after local opposition.
South Korea faces similar resistance despite naming AI data centers as a major investment priority alongside semiconductors. In Seoul's Geumcheon district, residents protested for 172 days as of mid-August against a planned data center near homes. The local government announced plans to require majority resident consent within 200 meters of proposed sites and introduced a three-stage review system for disputes.
Asya Walters, managing director at Alvarez & Marsal, told CNBC that a community's ability "to derail a $10 billion data center plan is quite powerful." She noted the U.S. business-friendly environment historically eases permitting, while Europe and Asia show "hot and coldness" toward data centers depending on country-level policies. Even unsuccessful projects drain operator resources. Walters said operators spend substantially before permits are secured, creating losses if approvals never materialize.
Equinix vice president Eulalia Flo stated the company does not view opposition as "a structural constraint on growth" but acknowledged "the policy environment is genuinely tightening in some markets." Dominic Ward, CEO of Verne, told CNBC the industry faces a "misunderstanding" now that data centers are visible. "We used to be a completely unknown part of the economy," he said. "Now we are one of the fundamental layers driving the economy. Now everybody knows where they are, so there's kind of no hiding behind this."
