Microsoft achieves water positivity in data center operations, reports 90% efficiency improvement

Summary

Microsoft announced it has achieved water positivity across its data center operations, meaning it replenishes more water than it consumes. The company reported a near-90% improvement in data center water use effectiveness (WUE) since the early 2000s, dropping from 2.3 L/kWh to 0.27 L/kWh in 2025. It also reduced water use intensity by 25% against a 2022 baseline, more than halfway toward a 40% reduction target for the decade. However, the company did not disclose absolute water consumption levels.
