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 → serialised registry record.
Net negativity
Full lifecycle accounting of the production process.
No double-counting
One serialised certificate per tonne, retired transparently.
Safety & regulatory
EU-jurisdiction, CRCF-aligned, real counsel on green claims.
The evidence trail
This is what a tonne looks like before you buy it
A demonstration batch, reconciled the way every real one will be: sensor against laboratory, uncertainty deducted, the conservative figure carried forward.

Sensor vs laboratory · gross tCO₂e/t, before deductions
The two chains disagree. In this illustration the laboratory's 2.90 enters the waterfall above as gross, and the sensor reading is logged for reconciliation. The certification methodology sets the rule; uncertainty is deducted, never averaged.

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
We apply the conservative rules of the certification methodology we adopt, based on accredited laboratory analysis. Uncertainty is deducted, never averaged.
1:1
serialised
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-Agro for 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: biochar is roughly 90% of the durable removals actually delivered and buyer numbers keep climbing, while delivery still trails what is contracted. 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
With a forward offtake, we agree the volume, price and schedule in advance, with payment tied to delivery of the issued credits.
Volume, price and schedule agreed · payment on delivery
Prepurchase
Pay a portion now, back the facility
With a prepurchase, the buyer pays part of the price in advance to support the development of the facility, on terms agreed in the contract.
Partial advance payment · contractual terms
Spot sales follow once issued credits exist. Price is set by contract, according to volume, delivery date and purchase structure.
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 18,000–26,000 tCO₂e a year at full operation. That is 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.
Offtake contracts
Offtakes with clear criteria
We are structuring our future offtake contracts with the support of a leading international consultancy. Each contract will set out volumes, price, delivery schedule, independent verification of the removals, and mechanisms to manage any delays or differences from the expected volume.

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.
