More than 100 civil society organizations and advocacy groups from 15 European countries staged coordinated protests on Saturday against the rapid expansion of energy-intensive data centers. Demonstrators cited concerns about power consumption, environmental damage and wider social impacts, and called for a pause on all new large-scale data center projects until clearer regulation is established. About 2,000 people marched in Dublin and roughly 1,300 gathered in Helsinki, while smaller Finnish towns also held demonstrations. Environmental and social groups from Scotland, Spain, France and Denmark joined the action, organized in part by the Stop Dirty Data Centers coalition, which opposes unconstrained AI data center growth and the influence of large technology companies on democratic institutions.
