Amazon pledges $20M to Colorado River conservation while keeping total water use undisclosed

Amazon has committed $20 million to water conservation projects along the Colorado River, backing a new collaborative that aims to raise $100 million over two years — even as the company declines to publish a complete account of how much water it actually consumes.

According to The Verge, Amazon announced the Colorado River Basin Collaborative with the stated ambition of building one of the largest corporate water conservation efforts ever focused on a single US watershed. Other participating companies can strike their own agreements with conservation projects, and the United Nations-backed Water Resilience Coalition will vet the work. Amazon is also joining that coalition, whose membership already includes Microsoft and Meta.

A strained watershed

The Colorado River stretches roughly 1,400 miles and supplies water to 40 million people across seven Western US states and two states in Mexico. The US Bureau of Reclamation describes the basin as having faced an "unprecedented" drought over the past 26 years, a crisis deepened by decades of overuse and human-driven climate change. In August, the Department of the Interior finalized a plan imposing steep water cuts on Arizona, Nevada and California.

As part of the new push, Amazon pledged $2.2 million over three years in Orange County, California — the state that hosts more Amazon warehouses than any other — to detect and repair leaks. The company says that effort should conserve 189 million gallons of water each year.

What Amazon discloses, and what it leaves out

In June, Amazon revealed that its data centers — whether owned, leased or shared — drew 2.5 billion gallons of water globally in 2025. Facilities the company operates directly cut their consumption by 2 percent year over year, which Amazon attributes to a 52 percent efficiency improvement since 2021. It says it now uses 0.12 liters of water per kilowatt-hour, which it claims is roughly seven times better than the data-center industry average.

But as The Verge points out, Amazon's sustainability reporting publishes only that per-unit efficiency figure back to 2021, not total water consumption over time. Sustainability experts and environmental advocates warn that efficiency metrics alone can mislead, because of the economic principle known as Jevons paradox: as a technology gets more efficient, overall resource use can still climb as companies deploy more of it. What matters is total consumption, and how much water is drawn in each location during demand peaks when supplies are tightest.

Amazon's peers are comparatively more open. Microsoft's latest sustainability report discloses total data-center water use going back to 2020, while Google reports water use for its global operations since 2021 with a geographic breakdown. Reuters reports that all three companies have abandoned data center projects after community pushback.

The electricity question

A 2025 Guardian investigation alleged that Amazon obscured its true consumption by choosing not to count "secondary" water use — the water consumed generating the electricity its facilities run on — when calculating progress toward sustainability goals, a decision the report linked to executive concern over "reputational risk." A leaked internal document cited by the Guardian put Amazon's 2021 consumption at 10.5 billion gallons (39.7 billion liters) once power generation is included, comparable to what about 95,000 US households use. The data-center figures Amazon released in June also exclude electricity-related water use, even though a majority of a data center's water footprint typically comes from that secondary source.

Amazon spokesperson Margaret Callahan told The Verge that the Guardian's story relied on "cherry-picked data from an outdated document" and drew fundamentally wrong conclusions, though she did not supply additional figures on the company's total historical water use. She noted that Amazon is 75 percent of the way toward its goal of becoming water positive by the end of the decade, returning three gallons for every four it used last year.

Chief Sustainability Officer Kara Hurst framed the Colorado River initiative as an extension of the collective-action model behind the company's Climate Pledge, arguing that water and climate are closely linked. The Verge also notes that Amazon's carbon footprint grew 16 percent in 2025, a trend seen industry-wide as companies race to build out AI.

Why it matters

One estimate put AI's global water consumption in 2025 at between 312.5 billion and 764.6 billion liters, and communities in the Colorado basin are already bracing for higher utility rates as water cuts take effect, with residents worried data centers will deepen the strain. A $20 million pledge is tangible help for the watershed, but without disclosure of total consumption — including the water embedded in electricity generation — outsiders cannot judge whether Amazon's replenishment claims keep pace with its actual, and growing, footprint. As the AI build-out accelerates, transparency rather than efficiency ratios will be the real test of corporate water commitments.
