Board scrutiny. Auditor questions. Journalists with a spreadsheet. Build a removal portfolio where every claim is already documented, down to the instrument reading.
Anyone can sell you a certificate. What determines whether it survives an audit is the data underneath it — and whether you can reach that data without asking permission.
Retirement records structured for GHG Protocol, SBTi, and CRCF reporting. Export straight into your disclosure.
Blend permanence profiles and price points across four pathways — hedge durability risk without overpaying for it.
Site visits, technical calls, and direct offtake negotiation. No broker layer between you and the project.
REST API and webhooks push retirements straight into your existing carbon accounting platform.
A thousand-year credit and a forty-year credit are not interchangeable, and paying DAC prices for everything is a poor use of budget. We help you build a blend that matches your actual claim.
Biological storage carries reversal risk — fire, disease, land-use change. Pretending otherwise is how the last generation of credits lost credibility.
We hold a buffer pool funded by a percentage of every issuance across all pathways. If a confirmed reversal affects credits you've retired, replacements are drawn from the pool at no cost to you. The pool balance is published monthly.
Discuss your portfolio →Our audit committee asked for source data on a random sample of twelve credits. We had all twelve on screen in under ten minutes. That had never happened before.
It depends entirely on pathway. Reforestation runs $45–95, biochar $120–180, enhanced weathering $180–320, and direct air capture $380–600. Most buyers land on a blended portfolio in the $90–160 range. Multi-year offtake reduces those numbers meaningfully.
Spot purchases start at 100 tonnes. Offtake agreements typically start at 1,000 tonnes per year — that's where the pricing and supply-security advantages actually appear. Below 100 tonnes we'll usually point you somewhere better suited.
Retirement records export in formats aligned with GHG Protocol and SBTi guidance, and our API pushes directly into most carbon accounting platforms. If you're using something custom, the REST endpoints are documented and stable.
Yes — all of it, before you commit anything. Measurement data, methodology version, verifier attestation, and site details are public for every project on the platform. You can audit a project's full record without talking to us.
Removals only. We don't list avoidance or reduction credits at all. Every tonne on the platform represents carbon physically taken out of the atmosphere and stored for a stated duration.
Credits measured on our instrumentation cannot be issued through another registry — that's contractual with every developer. Retirement is permanent and public, so any attempt to resell a retired credit is visible to anyone checking.
