Microsoft is reportedly reviewing one of its most ambitious climate commitments — the “100/100/0” goal to match 100% of its electricity use with zero-carbon sources on an hourly basis by 2030. The internal reassessment, disclosed by people familiar with the matter, comes as surging artificial intelligence workloads drive unprecedented power consumption across the company’s global data center network.
The 2021 pledge went far beyond standard annual renewable energy matching by requiring that every hour of every day, data centers would run on carbon-free power from the same regional grids. While Microsoft has already achieved its yearly renewable matching targets, maintaining the stricter round-the-clock standard is becoming increasingly difficult amid its massive AI infrastructure buildout.
That buildout is enormous: Microsoft has committed approximately $190 billion in spending through the end of the year, much of it directed toward data centers designed to support AI models and cloud services. As a result, the company’s energy consumption rose 168% from 2020 levels, and total Scope 1, 2, and 3 emissions increased 23.4% over the same period, according to its 2025 Environmental Sustainability Report.
To secure stable electricity supply, Microsoft is exploring new energy procurement strategies, including “behind-the-meter” natural gas projects in Texas that would supply data centers directly without relying on regional grids. These potential fossil fuel partnerships have raised concerns among climate advocates, who fear they could slow decarbonization progress. At the same time, the tech giant continues to sign long-term clean energy deals, recently securing 1.2 gigawatts of carbon-free projects in Wisconsin and partnering with Constellation Energy to restart a nuclear unit at Three Mile Island.
Microsoft is not alone. Rivals such as Meta, Google, and Amazon have all seen emissions climb since the launch of ChatGPT in late 2022, reflecting the broader energy challenges of the AI boom. Despite the uncertainty around the 2030 target, investor sentiment remained steady, with Microsoft’s stock holding broadly stable as the promise of AI growth continues to offset doubts about long-term climate pledges.
