The analysis

  • Water consumed, which does not return to the environment (mostly evaporated), doubled between 2020 and 2025.
  • 50% of withdrawals in fiscal year 2025 take place in water-stressed areas, according to the company.
  • Microsoft states that in 2025 it replenished more water than it withdrew (14 million m³): this is an offset, not a reduction in withdrawal.

The figures

  • Withdrawn: 6.8 million m³ in 2020, 13.3 million m³ in 2025.
  • Consumed: 4 million m³ in 2020, 8.2 million m³ in 2025.

Assumptions

  • The whole company, data centres included.
  • The series were recalculated in the 2026 edition; do not mix them with those of earlier reports.
  • The years 2021 to 2023 are not reproduced here.
  • The water of electricity generation and hardware manufacturing is not counted.
