Amazon's data centers consumed 2.5 billion gallons of water last year, the company said.

At the facilities the company owns and operates directly, the total amount of water Amazon withdrew decreased two percent from 2024 to 2025, despite the number of data centers increasing. The company did not disclose any change in water usage at the sites it leases.

Amazon Web Services owned some 28.37 million sq ft (2.64m sqm) of data center and office space in 2025 and leased another 28.469m sq ft (2.64m sqm), a previous 10-K filing revealed.
