Boards, auditors, journalists with a spreadsheet. Build a removal portfolio where the answer is already written down, right back to the instrument that took the reading.
Anyone can sell you a certificate. Whether it survives an audit comes down to what sits under it, and whether you can reach that without asking anyone's permission.
Retirement records already laid out for GHG Protocol, SBTi and CRCF reporting. Export them straight into the disclosure.
Mix permanence profiles and price points across four pathways, so you cover durability risk without paying top price for all of it.
Site visits, technical calls, offtake negotiated face to face. There is no broker sitting between you and the site.
A REST API and webhooks push retirements into whatever carbon accounting platform you already run.
A thousand-year tonne and a forty-year tonne are not the same thing, and paying capture prices across the board wastes budget. We help you build a mix that matches the claim you actually need to make.
Biological storage can reverse. Fire, disease, a change of land use. Pretending otherwise is how the last generation of credits lost the room.
A buffer pool, funded by a slice of every issuance across all four pathways, sits behind this. If a confirmed reversal touches credits you have already retired, replacements come out of the pool and cost you nothing. We publish the balance every month.
Discuss your portfolio →The audit committee picked twelve credits at random and asked for source data. We had all twelve on screen inside ten minutes. That had never once happened to us before.
Entirely down to pathway. Reforestation runs $45–95, biochar $120–180, enhanced weathering $180–320, direct air capture $380–600. Most buyers end up with a mix somewhere between $90 and $160. Multi-year offtake pulls all of those down.
Spot starts at 100 tonnes. Offtake usually starts at 1,000 tonnes a year, which is where the price and supply-security advantages actually show up. Under 100 tonnes we will generally point you somewhere better suited.
Retirement records export in formats lined up with GHG Protocol and SBTi guidance, and the API pushes into most carbon accounting platforms directly. If you have built something in-house, the REST endpoints are documented and we don't move them.
All of it, before you commit to anything. Readings, method version, verifier attestation and site details are public for every site on the platform. You can work through a site's whole record without speaking to us once.
Removals only. We don't list avoidance or reduction at all. Every tonne here is carbon physically taken out of the air and held for a stated period.
A tonne measured on our instruments cannot be issued through another registry, and that is contractual with every developer. Retirement is permanent and public, so reselling a retired credit is visible to anyone who looks.
