The corporate stated it needed to be carbon unfavorable by 2030.
Microsoft’s carbon emissions grew 25 p.c yr over yr in 2025, the corporate has revealed in its 2026 environmental sustainability report. The report covers the corporate’s 2025 fiscal yr and measures its progress in opposition to its 2020 baseline. Microsoft says this development in emissions is generally attributable to the enlargement of its investments in AI information heart infrastructure.
As GeekWire notes, Microsoft appears to be shifting in the wrong way of the place it desires to go with the intention to obtain its objective. The corporate introduced in 2020 that it plans to be carbon negative, or to take away extra carbon from the ambiance than it creates, by 2030. It solely has 4 extra years to get there.
“Whereas AI infrastructure is driving demand for power, water, land, and supplies, sustainability options usually are not scaling quick sufficient to satisfy demand,” it admits. The corporate is aware of it has to refine its “methods as circumstances change, information improves, and tradeoffs grow to be clearer.” Microsoft says that it isn’t reducing its ambitions as a result of AI calls for are outpacing sustainability options. During which case, the corporate has a whole lot of work forward of it. “We proceed to essentially be centered round carbon negativity by 2030,” Melanie Nakagawa, chief sustainability officer, advised GeekWire.
Along with AI infrastructure buildouts, one more reason why Microsoft reported a 25 p.c yoy development in carbon emissions, is as a result of it stopped shopping for unbundled renewable power certificates. One certificates signifies that an entity owns one megawatt-hour of zero-carbon electrical energy generated by a renewable supply and delivered to the grid. Microsoft says its resolution elevated its reported emissions within the close to time period, but it surely allows the corporate to concentrate on including all types of carbon-free electrical energy to the grids the place it operates quite than simply on counting on certificates. “We consider this modification will create extra long-term sustainability advantages,” it wrote.
Whereas it admits to emitting extra carbon in its report, Microsoft additionally highlights its successes for the fiscal yr of 2025. It says it matched one hundred pc of its annual world electrical energy consumption with renewal power. The corporate additionally replenished extra water than it withdrew globally, which pushes the corporate nearer in direction of attaining its objective to grow to be water positive by 2030.
