Amazon has disclosed for the first time that its global data center operations consumed 2.5 billion gallons of water last year, as growing demand for artificial intelligence infrastructure places renewed scrutiny on the environmental footprint of the world’s largest cloud providers.
The company presented the figure as evidence of improving efficiency, claiming its data centers are seven times more water-efficient than the industry average. Amazon says it has reduced reliance on potable water through alternative cooling methods and expanded the use of reclaimed wastewater across its facilities.
The disclosure comes amid increasing public concern over the resource demands of large-scale data centers, particularly those powering AI systems. These facilities require substantial amounts of electricity and cooling, placing pressure on local water supplies in some regions.
Amazon says many of its data centers rely primarily on outside air for cooling and only use water-based cooling systems during the hottest periods of the year. The company also reports operating 26 facilities that use 100% reclaimed water sourced from wastewater treatment plants, with more than 130 additional projects contracted globally.
The tech giant has set a goal of becoming “water positive” by 2030, meaning it aims to replenish more water than it consumes through conservation and restoration initiatives. Amazon says it has already achieved roughly 75% of that target.
The announcement follows earlier reports suggesting significantly higher water consumption figures. A leaked internal memo from 2022 projected Amazon’s data center network could consume 7.7 billion gallons annually by 2030. Investigations by media organizations also raised questions about the company’s transparency regarding water usage as its infrastructure footprint expands.
The debate highlights a broader challenge facing the technology sector. As companies race to build AI data centers capable of training and running increasingly powerful models, water consumption has emerged alongside electricity demand as a key environmental concern. Major cloud providers including Amazon, Microsoft, and Google are all investing heavily in new facilities while facing pressure from regulators, environmental groups, and local communities.
Amazon’s claim that its facilities are substantially more water-efficient than competitors may also invite scrutiny. Critics note that comparisons can be difficult because companies often measure efficiency differently, particularly when separating traditional cloud infrastructure from AI-focused data centers that use power-hungry graphics processors.
