Where it stands

Microsoft reported a 25% increase in carbon emissions for 2025, a spike linked to the boom in AI data centers. This growth includes an increase in the use of fossil fuels. According to The Guardian, big tech's carbon emissions from data centers have reached a third of those of France.

Coverage from Yahoo Finance, Wired, Windows Central, and TechRadar emphasizes the conflict between AI expansion and ESG goals. While reports from inkl and Tom's Hardware highlight the company's struggle to meet its 2030 sustainability promise, Microsoft's chief sustainability officer maintains that the target remains feasible. Attention now turns to whether Microsoft can align its carbon-heavy AI expansions with its stated sustainability targets.

Heatmap News indicates that electricity is not the only driver of these surging emissions.
