The Tucson city council voted unanimously to reject Amazon's planned Project Blue AI data center campus, while locals cheered the decision. Mayor Regina Romero said that the city would also look to place limits on future data centers "to protect Tucson from this industry that is already here in Arizona."

The Tucson City Council voted unanimously to kill Project Blue, a large data center proposed for land near I-10 and Houghton. Council members cited public opposition to the proposal, and concerns that the project would use far too much water and electricity to be appropriate in Tucson’s fragile desert environment.
