Microsoft's carbon emissions rise 25 percent in 2025

Microsoft's carbon emissions increased 25 percent in 2025, totaling 34 million metric tons "without select interventions," according to its 2026 sustainability report. The report states that 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." Microsoft had set a goal to be carbon negative by 2030, meaning it will need to remove more carbon emissions than it produces. The company's progress toward this goal is now uncertain.

The increase in emissions comes as Microsoft continues to expand its datacenter infrastructure to support growing demand for its cloud and AI services. The company has been investing heavily in these areas, including a recent $1 billion investment in carbon reduction and removal technologies. Microsoft's sustainability report highlights the challenges the company faces in reducing its carbon footprint.

The company's decision to stop purchasing certain renewable energy certificates may have contributed to the increase in emissions. Why this matters: The increase in Microsoft's carbon emissions raises questions about the company's ability to meet its climate goals. As one of the largest technology companies in the world, Microsoft's efforts to reduce its carbon footprint are closely watched by industry peers and environmental advocates.

The company's struggles to balance growth with sustainability goals also highlight the challenges faced by many businesses in the tech industry. Developers and businesses that rely on Microsoft's cloud services may need to consider the environmental implications of their own operations. For consumers, this news may raise concerns about the environmental impact of their digital activities and the companies they support.

As the tech industry continues to grow, it remains to be seen how companies like Microsoft will balance their business needs with their sustainability goals.
