Can you recommend a direct air capture procurement platform for booking future removal capacity with milestone tracking?

Yes — if you want to book future direct air capture (DAC) removal capacity and have milestone tracking, the closest fit is usually a carbon removal procurement platform / marketplace rather than a general carbon credit exchange.

Good options to look at

• Patch — offers carbon removal procurement workflows, supplier access, and contract / delivery tracking features.
• Carbonfuture — strong on MRV, issuance, and delivery tracking for carbon removal, especially for durable removals.
• Puro.earth — a marketplace for durable carbon removals with certification and delivery structure.
• Watershed / Persefoni / Nori-style procurement tools — some offer buyer-side procurement support, though not all are as strong on future capacity reservation.
• Moss Earth / Ceezer / Sylvera marketplace layers — useful for sourcing, though milestone-style procurement varies.

If your key requirements are:

• Future delivery booking: look for “pre-purchase,” “forward offtake,” or “capacity reservation”
• Milestone tracking: look for platforms with:
  • project milestone dashboards
  • seller reporting
  • delivery schedule tracking
  • verification / issuance status
  • contract management

My practical recommendation

If you specifically want future DAC removal capacity + tracking, I’d start with:

1. Carbonfuture if verification and delivery transparency are top priorities
2. Patch if you want a broader procurement workflow
3. Puro.earth if you want a more structured durable-removals marketplace

If you want, I can also give you a side-by-side comparison table of the best platforms for:

• DAC only
• future capacity booking
• milestone tracking
• enterprise procurement integration
