Microsoft Says Carbon Removal Program Continues as Procurement Pace May Shift After 45 Million-Ton Buying Year

Microsoft has said its carbon removal program is continuing and remains part of its broader climate strategy, responding to recent speculation that it had halted activity in the market. The company said its carbon removal effort “has not ended” and that it continues to support its existing portfolio across both nature-based and technology-based solutions. At the same time, Microsoft indicated that it may adjust the pace or volume of future procurement as it refines its sustainability approach.

That clarification matters because Microsoft has been the dominant force in voluntary carbon removal purchasing in recent years. Reports earlier this week suggested the company had told some suppliers it was pausing purchases, raising concerns about the potential effect on a market that has relied heavily on Microsoft demand to scale projects and signal quality standards. The updated statement does not suggest a retreat from carbon removal, but it does indicate a more measured procurement posture than some market participants had assumed.

 

Carbon removal remains central to Microsoft’s climate commitments

 

Microsoft’s carbon removal strategy is tied directly to its 2030 carbon negative target and its longer-term commitment to remove the equivalent of its historical emissions by 2050. The company continues to describe carbon removal as part of a broader decarbonisation model that combines emissions reduction, removal, and efficiency rather than relying on removals alone. Its public carbon removal program page remains active and still states that the company is accepting eligible proposals on a first-come, first-served basis.

This is important because it signals continuity in the company’s long-term climate architecture even if the near-term flow of deals becomes less aggressive. Microsoft has consistently framed removals as the mechanism for dealing with residual and historical emissions that cannot be fully addressed through operational reductions. That means the company’s latest statement is better understood as a possible recalibration of buying cadence, not a reversal of strategic direction. This interpretation is an inference based on Microsoft’s published program language and the new statement.

The market reaction reflects Microsoft’s outsized role

 

The reason the earlier reports created so much concern is simple: Microsoft has become far larger than any other corporate buyer in carbon removal. Recent market reporting said the company accounted for roughly 90% of the market in 2025, while Microsoft itself disclosed earlier this year that it had contracted a record 45 million metric tonnes of carbon removal in 2025, roughly double its 2024 total.

That scale means even a moderate slowdown from Microsoft can affect project finance expectations, supplier pipelines, and confidence in market growth. It also highlights a structural issue in the sector: demand has been concentrated in too few hands. Microsoft’s latest statement may therefore reassure the market that the company is still engaged, but it also reinforces how dependent the sector remains on one major buyer. This final point is an inference based on Microsoft’s relative purchasing scale.

What the update signals

 

The updated message from Microsoft changes the tone of the story. Instead of a clean break from carbon removal, the company is signaling continuity with more flexibility around timing and volumes. That is still meaningful for developers and suppliers, because future procurement may become less predictable even if the overall strategy remains in place.

For the market, the bigger takeaway is that carbon removal is entering a more disciplined phase. Microsoft still appears committed to the category, but its wording suggests that procurement scale will be managed more carefully against broader sustainability priorities and portfolio considerations. For suppliers, that means long-term opportunity remains, but the market may have to rely less on automatic expansion from its single biggest buyer. This is an inference based on Microsoft’s language about adjusting procurement pace and volume.
