Microsoftの排出量が30%増加 ― 原因はAIデータセンター
Microsoftの2026年サステナビリティレポートによると、AIデータセンターインフラの影響で炭素排出量が30%急増し、3,400万メトリックトンに達しました。この事実は、再生可能エネルギーソリューションでは生成AIの膨大なリソース需要を相殺できていないことを示しており、同社の2030年カーボンネガティブ目標が危機にさらされています。
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.
