Amazon announced a $20 million investment to fund water conservation projects along the Colorado River, a source that supplies water to roughly 40 million people across seven U.S. states and two in Mexico. The company described the move as part of a broader effort to become water positive by the end of the decade, meaning it aims to replenish more water than it consumes. The announcement coincides with growing scrutiny of water use by technology firms, particularly those operating large data centers that require significant amounts of water for cooling.

The Colorado River Basin Collaborative, which Amazon launched alongside the Water Resilience Coalition, a United Nations‑backed initiative, plans to raise $100 million over two years for watershed restoration and leak detection projects. In addition to its own contribution, the collaborative invites other corporations to contract directly with vetted conservation projects. Participating companies include Microsoft and Meta, among others.

Amazon has previously disclosed limited details about its water footprint. In June, the company reported that its data centers consumed 2.5 billion gallons of water globally in 2025, a figure that includes water used for cooling and other operational needs. It also noted a 2 percent reduction in water use by facilities it owns and operates compared with the prior year, attributing the improvement to a 52 percent increase in water efficiency since 2021. The company measures efficiency as 0.12 liters of water per kilowatt‑hour of electricity, a metric it says is seven times more efficient than the industry average.

Environmental researchers caution that efficiency gains can be offset by increased overall consumption, a phenomenon known as Jevons paradox. They argue that tracking total water use, especially during peak demand periods, is essential for understanding a company’s true impact. Unlike some peers, Amazon has not publicly disclosed total water consumption across its operations over multiple years, instead reporting only efficiency ratios.

A 2025 investigation by The Guardian alleged that Amazon underreports its water use by excluding "secondary" water consumption tied to electricity generation. According to leaked internal data cited by the report, Amazon used approximately 10.5 billion gallons of water in 2021 for power plant cooling, a volume comparable to the annual consumption of about 95,000 U.S. households. Amazon’s spokesperson, Margaret Callahan, rejected the findings, describing the analysis as "cherry‑picked" and based on outdated documentation. She emphasized that the company is 75 percent toward its water‑positive goal, returning three gallons for every four it uses.

Kara Hurst, Amazon’s chief sustainability officer, framed the Colorado River initiative as an extension of the company’s Climate Pledge, suggesting that collaborative action can accelerate progress. She highlighted the interconnectedness of water and climate challenges.

The broader context includes rising opposition to new data center construction in regions such as Arizona, where water cuts are being imposed to address the river’s prolonged drought. Critics warn that expanding digital infrastructure could strain already limited water supplies. Meanwhile, other technology firms have begun publishing more detailed water usage data, with Microsoft reporting total water consumption since 2020 and Google providing location‑specific figures since 2021.

The situation underscores the difficulty of measuring sustainability in an industry whose growth is closely linked to both energy and water resources.
