Microsoft carbon emissions rise 25% in 2025 as AI data centre growth strains climate goals

Microsoft's 2026 Sustainability Report shows a 25% increase in carbon emissions for 2025, reaching 34 million metric tons. The company attributes the rise to rapid expansion of AI data centre infrastructure and a decision to stop buying unbundled renewable energy certificates. This puts Microsoft's goal of becoming carbon negative by 2030 under serious pressure. The report highlights a broader tech sector trend. Google and Amazon also reported emission increases of 25% and 16% respectively, driven by AI infrastructure buildout. Microsoft notes that sustainability solutions are not scaling fast enough to match demand from data centres for energy, water, land, and materials. The company still aims to be carbon negative by 2030 but faces a widening gap between infrastructure growth and clean energy deployment.

Microsoft's 25% emissions jump is a direct result of AI data centre buildout. They stopped buying unbundled RECs, which is honest but makes the number look worse. The real question is whether their 2030 carbon negative target is still credible.

34 million metric tons is a lot. The report says 'without specific interventions' which suggests they have a plan but it is not working fast enough. I wonder how much of that is from grid mix in regions where they built new data centres.

That is the key detail. If they built in grids with high coal or gas share, the emissions jump is inevitable. The report mentions stopping unbundled REC purchases which means they are not masking the real grid impact anymore. That is actually more transparent.

The unbundled REC shift is a big deal. It means Microsoft is now accounting for actual grid emissions rather than buying cheap offsets. That is the right move for transparency but it makes their 2030 target look much harder. The policy question is whether carbon accounting rules should require this.

34 million metric tons is huge. For context that is roughly the annual emissions of a small country. The data centre energy demand is real but the solution is not just offsets. It is about siting new facilities where the grid is already clean or pairing them with dedicated renewables from day one.
