Microsoft's emissions rose 25% year-over-year to 20.3 million metric tonnes CO2e in FY2025, driven primarily by rapid data center expansion to support AI workloads. The spike signals mounting infrastructure costs and regulatory pressure for cloud and AI companies scaling compute capacity.
This Wire brief sits within Fusion42's coverage of AI Infrastructure and Cloud Infrastructure.
◆ ◆ The Wire takeaway
If you're selling power, cooling, or grid services to data centres, Microsoft just proved the market will absorb massive cost increases to chase AI revenue. Regulators now have hard proof that scaling AI without emissions solutions is politically unsustainable—that's your regulatory window to sell green infrastructure, not a threat.
