Where authorities are restricting data centres amid AI boom

New York State, U.S.

Governor Kathy Hochul imposed a one-year construction moratorium on data centers using 50 megawatts (MW) or more of power, making New York the first U.S. state to enact a full moratorium.

During the freeze, the state's Department of Environmental Conservation will not issue new discretionary permits while officials develop standards to assess the environmental impact of data centers.

Maine, U.S. (vetoed)

Governor Janet Mills vetoed bipartisan legislation that would have enacted an 18-month moratorium on new data centers using more than 20 MW of power, a measure that would have been the first of its kind in the U.S.

Mills said she supported a moratorium in principle but objected to the bill's failure to carve out an exception for a specific project in the Town of Jay.

Monterey Park, California, U.S.

Residents voted to permanently ban data centers in the city in June 2026, becoming the first U.S. city to do so at the ballot box, following public backlash over a planned facility.

Amsterdam, Netherlands

The city imposed a one-year moratorium on new data centre developments in 2019. In April 2025, it barred new data centers or expansions in the municipality until at least 2030.

Separately, the Dutch national government's 2022 hyperscale ban restricts large facilities to two designated locations nationally, though Microsoft MSFT.O won approval in January 2026 for a project split into three towers, each individually below the size threshold.
