Microsoft’s carbon emissions went up 25 percent last year

Microsoft may once again be struggling to keep up with its own climate goals, according to its 2026 sustainability report. As reported by GeekWire, the report states that Microsoft’s carbon emissions increased 25 percent in 2025, totalling 34 million metric tons “without select interventions.” Microsoft says this was “driven primarily by the expansion of our datacenter infrastructure,” as well as the company’s decision last February to stop purchasing “non-additional, unbundled renewable energy certificates.”

Several years ago, Microsoft set itself a goal to be carbon negative by 2030, meaning it will need to remove more carbon emissions than it produces. This isn’t the first time Microsoft has faced setbacks toward accomplishing that goal, as its 2024 sustainability report showed a similar rise in climate pollution. This year’s report admits that, “While AI infrastructure is driving demand for energy, water, land, and materials, sustainability solutions are not scaling fast enough to meet demand.”
Google similarly reported a 25 percent spike in its supply chain emissions in its 2026 sustainability report, with Amazon reporting a slightly lower 16 percent increase. In June, Amazon also reported that its data centers used 2.5 billion gallons of water in 2025, which it claims is less than Microsoft used.

Facts Only

* Microsoft's carbon emissions increased 25 percent in 2025, totaling 34 million metric tons without select interventions.
* The increase was attributed to the expansion of datacenter infrastructure and stopping the purchase of "non-additional, unbundled renewable energy certificates" in February.
* Microsoft's annual sustainability report notes that sustainability solutions are not keeping up with AI demands.
* Microsoft set a goal to be carbon negative by 2030.
* Microsoft's 2024 sustainability report showed a similar rise in climate pollution compared to previous years.
* Google reported a 25 percent spike in its supply chain emissions in its 2026 sustainability report.
* Amazon reported a 16 percent increase in supply chain emissions.
* Amazon's data centers used 2.5 billion gallons of water in 2025, which Amazon claims is less than Microsoft’s usage.

Executive Summary

Microsoft's carbon emissions increased by 25 percent in 2025, totaling 34 million metric tons without specific interventions. This increase was attributed primarily to the expansion of datacenter infrastructure and a decision to cease purchasing certain renewable energy certificates in February. The company acknowledges that while AI infrastructure drives energy, water, land, and material demand, current sustainability solutions are not scaling fast enough to meet this demand. In parallel, competitors showed similar trends; Google reported a 25 percent spike in supply chain emissions in its 2026 report, and Amazon reported a 16 percent increase. Furthermore, Amazon stated that its data centers used 2.5 billion gallons of water in 2025, which is less than Microsoft's reported usage.

Full Take

The narrative reveals a systemic tension between technological advancement, specifically the demands of AI infrastructure, and the capacity of current sustainability frameworks to manage that demand. The pattern observed across major technology entities—Microsoft reporting an emissions surge driven by infrastructure expansion, and the subsequent admission that solutions lag behind AI's energy appetite—suggests a structural misalignment where growth objectives are prioritized over incremental sustainability scaling. This echoes historical patterns where ambitious long-term goals (like carbon negativity) face iterative setbacks when immediate, large-scale technological shifts demand exponential resource consumption. The juxtaposition of reported emissions and water usage among competitors indicates that while performance metrics exist, the collective response remains fragmented rather than integrated toward a singular solution capable of handling AI-driven scaling. The implication for agency lies in recognizing that progress requires not just setting targets but fundamentally restructuring the operational assumptions around infrastructure and supply chain growth to match those scientific realities. What mechanisms are being overlooked when focusing solely on reporting aggregate increases instead of mandating structural shifts? How does this disparity between stated goals and reported reality influence public trust and future regulatory action?
