Microsoft faces clean energy challenge as AI infrastructure spending climbs

Microsoft is reconsidering one of its biggest climate commitments as spending on artificial intelligence infrastructure continues to surge.

According to a Bloomberg report citing people familiar with the matter, the company is debating whether to delay or drop its “100/100/0” clean energy target tied to its 2030 sustainability plans.

The pledge, announced in 2021, requires Microsoft to match all of its electricity use with zero-carbon energy every hour and in the same regional grids where the power is consumed. The standard goes beyond annual renewable matching, which only requires companies to buy enough clean energy over a full year to offset their consumption.

The discussions come as Microsoft rapidly expands data center capacity to support AI products such as Azure and Copilot. The company has already achieved annual renewable energy matching, but maintaining round-the-clock carbon-free power has become harder as electricity demand climbs. 

Rising energy use has also pushed Microsoft’s emissions higher. In its 2025 Environmental Sustainability Report, the company said total Scope 1, 2, and 3 emissions increased 23.4% from 2020 levels, partly due to AI and cloud expansion. Energy consumption rose 168% during the same period, while revenue increased 71%.

Other major tech companies are facing similar pressure as AI infrastructure grows. Bloomberg reported that emissions at Meta, Google, Amazon, and Microsoft have all climbed since the release of ChatGPT in late 2022. Some planned data center projects now require several gigawatts of power, enough to supply hundreds of thousands of homes.

Microsoft has continued signing energy deals to support its operations. The company recently secured agreements for 1.2 gigawatts of carbon-free energy projects in Wisconsin and also partnered with Constellation Energy to support the restart of a nuclear unit at Three Mile Island. 

At the same time, reports suggest Microsoft has explored natural gas projects in Texas as power demand from AI systems accelerates.

The situation highlights how the AI boom is reshaping energy planning across the technology sector.

Research firms, including BloombergNEF and the International Energy Agency, expect data center electricity demand to rise sharply over the next decade as cloud computing and AI workloads continue expanding.
