Episode notes
Microsoft Is The Carbon Removal Market
- Microsoft dominates the carbon removal market by purchasing roughly 75 million tons, dwarfing the next biggest buyer at 1.8 million tons.
- That concentration means Microsoft effectively created demand and price signals for an industry that otherwise had almost no buyers.
Startups Built Around Microsoft's Promise
- Robinson Meyer recounts that Microsoft bought almost nothing in 2021 and then scaled to 75 million tons, creating many startups that assumed Microsoft would be the buyer.
- CEOs and analysts told Meyer firms' business models relied on Microsoft's purchases to exist.
Most Tons Are Promises Not Delivered
- Microsoft's contracts are purchase-on-delivery commitments that buyers use to secure financing for building removal capacity.
- Many of the 75 million tons are promises tied to future projects, so pausing lets Microsoft assess which startups can actually deliver removals.
