Microsoft carbon emissions surge by 25 percent in 2025
Annual sustainability report reveals a significant spike in Microsoft carbon emissions due to expanding infrastructure
Microsoft struggled to maintain progress toward its long-term environmental targets after its greenhouse gas pollution surged significantly last year. The technology giant released its 2026 sustainability report showing that Microsoft's carbon emissions increased by 25 percent throughout 2025, reaching a total of 34 million metric tons without select interventions. Corporate leaders attributed the environmental setback directly to the rapid physical expansion of the global datacenter infrastructure required to support modern technology.
GeekWire reported that the company also blamed the pollution increase on a specific policy decision made last February to halt the purchase of unbundled, non-additional renewable energy certificates. The dramatic rise in Microsoft carbon emissions complicates a previous corporate pledge established several years ago to become entirely carbon negative by 2030. That specific environmental objective requires the organisation to actively remove substantially more carbon dioxide from the atmosphere than its global operations produce.
The latest data does not represent the first instance of the company facing severe challenges regarding its climate objectives, as the 2024 sustainability report detailed a comparable upward trajectory in pollution. The 2026 document acknowledged that while artificial intelligence infrastructure currently drives massive demand for energy, water, land, and physical materials, global sustainability solutions are simply not scaling fast enough to meet that growing consumption.
The environmental difficulties mirror broader trends across the technology sector as rival corporations expand their computing networks. Google similarly disclosed a 25 percent spike in its supply chain emissions within its own 2026 sustainability report, while Amazon reported a slightly lower 16 percent increase. Furthermore, Amazon published data in June indicating that its datacenters consumed 2.5 billion gallons of water during 2025, a figure that the online retail giant claimed was less than the total volume used by Microsoft over the same period.
