Microsoft Pauses Future Carbon Removal Purchases Amid AI-Driven Power Surge

Since 2020 Microsoft has positioned itself as a leading buyer of carbon removal credits, aiming to become carbon negative by 2030 and to erase all historic emissions by 2050. To spur the market, the company signed long‑term contracts with early‑stage firms, promising payment if they can verifiably sequester CO₂. Those deals have totaled several billion dollars over the last five years.

Microsoft informed select partners that it will pause future CDR credit purchases, though it says the 2030 carbon‑negative goal remains unchanged. Over the past half‑decade the tech giant has committed billions of dollars to support speculative removal companies through forward purchase agreements. Meanwhile, the Global Carbon Project reports that all existing CDR technologies together removed less than 1 % of annual global CO₂ emissions in 2023, a figure derived from atmospheric monitoring stations and national inventories aggregated yearly.

The pause reflects a shift in Microsoft’s capital allocation as AI‑driven workloads raise data‑center power demand, increasing reliance on fossil‑fuel‑based electricity in the short term. While the company maintains its long‑term climate targets, the slowdown could curb early revenue for CDR startups that relied on Microsoft’s off‑take contracts. Investors and policymakers will watch whether other large buyers step in to fill the gap and how Microsoft balances AI growth with its carbon‑negative ambition. What to watch next: whether Microsoft revises its CDR procurement strategy as AI energy consumption trends become clearer over the next 12‑18 months.
