San Francisco (旧金山) enacted an immediately effective 45-day moratorium on new data centers following a unanimous supervisory-board vote.

The moratorium was adopted unanimously and took immediate effect. The supplied report says San Francisco’s Board of Supervisors voted on Tuesday for a 45-day pause on new data centers. It describes a restriction on new development, not an order closing existing facilities.

The ordinance permits an extension, but that is not the duration already enacted. The report says the pause can be extended to approximately two years, while city officials consider longer-term restrictions. The initial operative period remains 45 days.

The sponsors highlighted a specific neighborhood and development. They referred to a project in Bayview-Hunters Point (湾景-猎人角), which already contains other data-center facilities, and cited existing air-pollution burdens and environmental-equity concerns. The report also identifies water consumption, electricity costs, and environmental effects as concerns behind restrictions elsewhere in the United States, but supplies no capacity or cost figures for the San Francisco project.
