Microsoft's emissions rose 30% — and it blames AI datacenters
microsoft's 2026 sustainability report shows carbon emissions jumped 30%, hitting 34m metric tons, driven by ai datacenter infrastructure. the admission signals that green energy solutions are failing to offset the massive resource demands of generative ai, putting the company's 2030 carbon negative goal at risk.
microsoft's 2026 sustainability report reveals that the company's carbon emissions rose by 30% in 2025, totaling 34 million metric tons, marking a significant setback in its quest to be carbon negative by 2030. the report identifies the expansion of datacenter infrastructure to support ai as the primary driver, noting that sustainability measures are failing to keep pace with the demands of ai for energy, water, and land. microsoft stopped purchasing 'non-additional, unbundled' renewable energy certificates in 2025, a decision that contributed to the spike but highlights the difficulty of offsetting ai's load. peers like google and amazon reported similar increases, with amazon noting 2.5 billion gallons of water used for datacenters, underscoring a systemic industry issue. the data confirms that the rapid scaling of generative ai infrastructure is currently incompatible with established corporate climate targets.
