▶ The 2-minute explainer

Summary

Microsoft's 2026 sustainability report indicates a 25% increase in carbon emissions in 2025, primarily due to expanding data center infrastructure and a change in renewable energy certificate purchasing. This rise challenges the company's goal to be carbon negative by 2030.

Microsoft's latest sustainability report reveals a significant setback in its environmental objectives, with carbon emissions increasing by 25% in 2025. The company reported a total of 34 million metric tons of emissions, attributing this surge primarily to the rapid expansion of its global data center infrastructure.Another contributing factor was Microsoft's decision to cease purchasing "non-additional, unbundled renewable energy certificates" in February of the previous year. This increase puts pressure on Microsoft's ambitious target of achieving carbon negativity by 2030, requiring substantial efforts to reverse the current trend.
