For carbon-credit buyers
Durable removals you can actually verify
Lab-grade, CRCF-aligned permanent carbon removal — measured at the plant, conservatively counted, traceable to retirement. First deliveries follow our 2027 production start; early offtake secures them.
Diligence starts here: where we stand, who is building this and the sites behind the tonnes.
Vetting
Every tonne meets the bar
The criteria high-integrity buyers hold suppliers to — and how we meet them.
Durability
Permanence engineered for several centuries — the CORC200+ class — and measured, batch by batch, by R₀ petrography. We claim what the lab result supports, never more.
Additionality
Removal that would not happen without the credit revenue.
Verifiability
Accredited lab → CRCF-native dMRV → serialized registry record.
Net negativity
Full lifecycle accounting of the production process.
No double-counting
One serialized certificate per tonne, retired transparently.
Safety & regulatory
EU-jurisdiction, CRCF-aligned, real counsel on green claims.
Quality
Independently anchored
Measured
not estimated
Permanence will be quantified per batch by accredited laboratories — from the carbon structure itself, not inferred from process settings.
Conservative
by rule
Where two measurement chains disagree, the lower value is carried forward. Uncertainty is deducted, never averaged.
1:1
serialized
One certificate per tonne, retired on a public registry — traceable back to the batch that produced it.
Standards we build to — not certifications we hold
Certification path
Targeting Puro.earth (CORC200+) and Isometric for credits, and EBC-Agrofor product — with the World Biochar Certificate (WBC) for our African sites — and the whole evidence chain mapped to the EU's CRCF (Delegated Regulation (EU) 2026/285).
Credit products
Two registries, one standard of proof
Puro.earth · primary route
CORC200+
The CO₂ Removal Certificate from the largest engineered-removal registry, in the several-centuries durability class. Broad market recognition and liquidity — familiar to corporate buyers and rating agencies alike, and the registry that has applied for recognition as an EU CRCF certification scheme.
Widely recognised · exchange-listed · rating-covered
Isometric · alternate route
Isometric credit
A science-led registry with the strictest published verification in the market, and its own biochar protocol. The route for buyers whose diligence bar is set by the science rather than by market liquidity.
Science-led · strict verification · public protocol
Puro.earth is our primary route; Isometric is available where a buyer's diligence calls for it. Both draw on the same laboratory-measured, dMRV-verified data, and a tonne is issued once — on one registry, never both. Definitions in the glossary.
How to contract
Secure future volume now
Durable supply is scarce and tightening. Both structures fix your terms today, ahead of the 2027 production start — priced per contract, volume and registry.
Forward offtake
Commit now, pay on delivery
A multi-year agreement that reserves your volume and fixes your price today. Payment follows each certified delivery — your exposure is the schedule, not the balance sheet.
Volume reserved · price fixed · pay on delivery
Prepurchase
Pay a portion now, deliver first
An upfront payment against future certified tonnes — the structure that helps build the capacity it buys. It carries first priority on first-site volume and the strongest terms we offer.
Paid upfront · first allocation · strongest terms
Spot sales follow once certified tonnes exist. We publish no indicative price we would not honour — pricing is agreed per contract.
Build your offtake
Shape your removal package
Set out what you need and we will price it — volume, delivery window and registry route.
For scale: Facility 1 is designed for an estimated 25,000–35,000 tCO₂e a year at full operation — a design estimate, replaced by measured data as the site runs.

Pricing is agreed per contract — it depends on volume, delivery window and registry route. We publish no indicative price we would not honour.
Not a quote or an offer — pricing is agreed per contract, project and registry.
Delivery risk
And if we are wrong?
We tell buyers to ask every supplier this question — so here is our own answer, for a plant that starts producing in 2027.
We count short on purpose
Certified volume is engineered to come in under the design figures, not over: the lower of two measurements is carried forward, uncertainty is deducted, and we contract against conservative volumes — a buffer by arithmetic, not by promise.
Replacement before refund
If a batch falls short of certification or a window slips, the contract schedules replacement tonnes from subsequent production first — with a refund backstop if we cannot deliver at all. Non-delivery is a contractual remedy, not a negotiation.
You see it early
The evidence trail accumulates in view of the buyer — batch records, laboratory results, the audit pack — so a schedule at risk is visible months out, not announced after the deadline.

Set your volume, window and registry above — the figures carry into the form, so the first reply already speaks to your package rather than asking you to repeat it.
What early offtake buys
- Priority on first-site volume, with delivery scheduled in the contract.
- The evidence trail as it accumulates — not a certificate at the end.
- A price agreed today, in a market where durable supply is tightening.
