Inside Microsoft’s two-decade push to cut water intensity while scaling for growth
Summary
Microsoft is introducing its water resource management achievements and technological innovations over the past 20 years in response to the rapid increase in demand for cloud and AI services, reducing the water use intensity of data centers, and achieving the 2030 water positive goal.
Key Points
- Since the construction of the first data center in the early 2000s, water use efficiency (WUE) has been improved by about 90% through innovations in cooling technology, lowering the average WUE from 2.3 L/kWh to 0.27 L/kWh as of 2025.
- Under the goal of improving data center water use intensity by 40% by 2030, a 25% reduction has already been achieved by 2025, exceeding half of the target.
- In fiscal year 2025 (FY25), we achieved the 'Water Positive' milestone of returning more water than we take in across our global business, and in 2024, we introduced a new AI-optimized data center design that does not use any water for cooling during operation.
