Gov. Gavin Newsom has vetoed legislation that would have required data centers to report how much water they use. … Assembly Bill 93, introduced by Assemblymember Diane Papan (D-San Mateo), would have required new data centers to disclose their expected water use when they apply for a business license and would have required all to report their water consumption annually. In a message explaining his decision Saturday, Newsom said the widespread adoption of AI “is driving an unprecedented demand for data center capacity throughout the nation.”
