Microsoft Reports 25 Percent Carbon Emissions Rise Tied to Expanding AI Workloads

Microsoft disclosed a 25 percent year‑over‑year increase in its carbon emissions, attributing the rise primarily to the power needed for training and running large AI models across its global cloud data centers.

AI workloads now represent roughly half of Microsoft’s added emissions, according to internal calculations, highlighting the growing energy toll of Azure OpenAI and other generative‑AI services as they scale for enterprise customers.

Carbon tracking frameworks described in recent business guides are being rolled out by Microsoft to capture scope‑1, scope‑2 and scope‑3 emissions with real‑time monitoring, third‑party verification and renewable‑energy procurement metrics, aiming to meet its 2030 net‑zero pledge.

Industry analysts cite the IEA’s 2026 energy policy review, which warns that AI‑driven computing could add several gigawatts of demand worldwide and urges governments to create efficiency standards and incentives for data‑center power use, underscoring Microsoft’s challenge to curb its carbon growth.
