Announced with much fanfare six years ago, Microsoft’s 2030 carbon negative goal now looks increasingly difficult to achieve. The company’s emissions have increased significantly from its 2020 base year, driven by a large capex cycle in AI infrastructure, and show no signs of slowing down. Microsoft has committed to approximately $80 billion in data center spending in fiscal year 2025 alone [1].
Chief Sustainability Officer Melanie Nakagawa said in an interview accompanying the report that the company remains committed to achieving its goals. Microsoft is pursuing multiple decarbonization strategies simultaneously, including its position as the world’s largest independent purchaser of durable carbon removal, accounting for 78.5% of total disclosed durable CDR tons contracted through April 2026.

The company has signed renewable power purchase agreements for up to 40 GW in 26 countries, of which 19 GW is currently in operation. Microsoft has stated that 100% of the world’s annual electricity consumption goes toward renewable energy purchases, but the distinction between renewable energy purchases and actual consumption at the point of generation remains a subject of debate among climate analysts.
