Amazon Web Services (AWS) has disclosed for the first time the total amount of water consumed by its global data center operations, revealing that its facilities withdrew approximately 2.5 billion gallons of water in 2025.

The announcement marks a significant step toward greater transparency as technology companies face growing scrutiny over the environmental impact of rapidly expanding artificial intelligence and cloud computing infrastructure.

AWS Reports Major Water Efficiency Gains

AWS reported a Water Usage Effectiveness (WUE) rating of 0.12 liters per kilowatt-hour, representing a 52% improvement since 2021. According to the company, this level of efficiency is roughly seven times better than the industry average of 0.84 liters per kilowatt-hour.

Despite continuing to expand its global data center footprint, AWS said water withdrawals at directly owned and operated facilities declined by 2% compared to the previous year.

The company attributed much of the improvement to increased use of advanced air-cooling technologies, which reduce the need for water-intensive cooling systems that are commonly used in large-scale data centers.

Why Data Centers Need Water

Water plays a critical role in cooling servers and networking equipment that power cloud computing services and artificial intelligence applications.

As demand for AI infrastructure continues to surge, data centers are consuming increasing amounts of electricity and water to maintain safe operating temperatures.

AWS noted that approximately two-thirds of the water it withdraws is returned through community water replenishment and infrastructure projects designed to improve local water availability.

Amazon's Goal: Become Water Positive by 2030

Amazon has pledged to become "water positive" by the end of the decade, meaning it aims to return more water to communities and ecosystems than it consumes across its operations.

The company believes investments in conservation programs, water recycling projects, and efficiency improvements will help achieve that goal.

The disclosure provides investors and policymakers with a clearer picture of the environmental footprint associated with the world's largest cloud computing business.

Pressure Mounts on Big Tech

The release of AWS's total water consumption figure could increase pressure on other technology giants to provide similar disclosures.

Until now, many cloud providers have primarily reported efficiency metrics rather than absolute water usage figures. While those ratios show improvements in resource management, they do not reveal the total amount of water being consumed as data center networks expand.

Industry observers expect companies such as Microsoft, Google, and Meta to face growing calls from investors, regulators, and local communities to publish comparable data.

Data Center Growth Faces New Challenges

The timing of AWS's disclosure comes as several local governments around the world are reconsidering new data center projects due to concerns about water and energy consumption.

Communities in water-stressed regions have increasingly questioned whether large data centers should receive priority access to limited resources when residential and agricultural users are facing shortages.

In some areas, authorities have introduced restrictions or temporary moratoriums on new data center construction while evaluating their environmental impact.

Investor Implications

For investors, AWS's improved water efficiency demonstrates the company's ability to lower operating costs while expanding capacity. Reduced water consumption can help improve profitability over time, especially as water prices continue to rise in many regions.

At the same time, the disclosure highlights a growing challenge facing the cloud computing and artificial intelligence industries. As demand for digital infrastructure accelerates, companies must balance growth ambitions with increasing environmental expectations from regulators, customers, and local communities.

AWS's decision to publish its total water usage could establish a new industry benchmark and shape future discussions around sustainability, resource management, and the long-term expansion of AI-powered data centers.
