Microsoft’s carbon emissions went up 25 percent last year
Microsoft reported a 25 percent increase in carbon emissions for 2025, largely driven by the massive energy demands of expanding its data center infrastructure for AI. The company is struggling to meet its goal of becoming carbon negative by 2030 as sustainability efforts fail to keep pace with technological growth.
Why it matters
The report highlights the significant environmental trade-offs and sustainability challenges inherent in the rapid global expansion of artificial intelligence infrastructure.
Microsoft may once again be struggling to keep up with its own climate goals, according to its 2026 sustainability report. As reported by GeekWire, the report states that Microsoft’s carbon emissions increased 25 percent in 2025, totalling 34 million metric tons “without select interventions.” Microsoft says this was “driven primarily by the expansion of our datacenter infrastructure,” as well as the company’s decision last February to stop purchasing “non-additional, unbundled renewable energy certificates.”
