According to Microsoft's 2026 sustainability report, the company's carbon emissions rose by 25 percent in 2025, reaching a total of 34 million metric tons. This increase is attributed to the expansion of its datacenter infrastructure and a decision made in February 2025 to stop purchasing non-additional, unbundled renewable energy certificates. Microsoft has set a goal to be carbon negative by 2030, which requires the company to remove more carbon emissions than it produces.
