Microsoft’s carbon emissions went up 25 percent last year

Microsoft's carbon emissions increased 25 percent in 2025, driven primarily by expansion of its datacenter infrastructure and a decision to stop purchasing certain renewable energy certificates. The company set a goal several years ago to be carbon negative by 2030, meaning it would need to remove more carbon emissions than it produces, but this is the second consecutive year it has reported significant emissions increases. According to Microsoft's sustainability report, artificial intelligence infrastructure is creating energy demands that sustainability solutions cannot yet scale to meet. Other major tech companies similarly reported substantial emissions increases, with Google reporting a 25 percent spike in supply chain emissions and Amazon reporting a 16 percent increase.
