Microsoft reported a 25% rise in carbon emissions in 2025, reaching 20 million metric tons, driven by the expansion of AI data centers. The increase puts the company's 2030 goal of being carbon negative at risk. Microsoft also paused buying renewable energy credits, which affected its reported emissions. Globally, data center emissions are expected to nearly double by 2035, highlighting the tension between AI growth and climate commitments. The story is worth reading because it shows how fast AI infrastructure is scaling and how hard it is for even well-resourced companies to keep emissions in check. It raises real questions about whether voluntary climate targets can survive when demand for compute power surges. For anyone tracking carbon markets or corporate climate pledges, this is a concrete example of the gap between ambition and reality.
