Microsoft Carbon Emissions Surge by 25 Percent

The company attributes this sharp increase primarily to the rapid expansion of its datacenter infrastructure required to sustain AI workloads. A shift in accounting policy also played a role; last February, Microsoft discontinued the purchase of non-additional, unbundled renewable energy certificates, a move that revealed a clearer, albeit more troubling, picture of its actual climate footprint. The latest sustainability report acknowledges that existing solutions are failing to keep pace with the energy, water, and material demands of modern AI development.

This trend is not isolated to Redmond. Google reported a identical 25 percent increase in supply chain emissions, while Amazon recorded a 16 percent rise. The sector faces mounting pressure as data center resource consumption continues to climb. Amazon recently disclosed that its own facilities consumed 2.5 billion gallons of water during 2025, highlighting the broader industry struggle to balance aggressive technological scaling with ambitious climate pledges.
