"What's a biochar carbon credit worth?" is the first question most developers ask — and the honest answer is it depends, with every figure an estimate. This guide gives realistic ranges and, more usefully, explains what actually drives the rate per tonne so you can earn more.
What does a biochar carbon credit cost per tonne?
Treat this as a starting reference, not a quote. Two projects can price very differently for the same tonne of CO₂ depending on the factors below.
What drives the price per tonne?
Price is not one number — it's the sum of how well a project scores on durability, measurement and reliability.
| Driver | Pushes price UP | Pushes price DOWN |
|---|---|---|
| Permanence (H/Corg) | Low ratio, long durability | Borderline or unproven permanence |
| MRV quality | Conservative, audit-ready, digital | Thin data; weak sampling |
| Feedstock | Sustainable, traceable genuine waste | Questionable additionality/provenance |
| Volume & delivery | Reliable, sizeable, on schedule | Small, uncertain, late |
| Standard & ratings | Recognised methodology, CCP-aligned | Obscure or contested pathway |
| Co-benefits | Credible, measured soil/livelihood gains | Claimed but unevidenced |
The pattern is consistent: integrity is priced. The single fastest way to lose price (or the sale) is weak MRV — which is why we treat biochar MRV as the foundation of value, not an afterthought.
Spot vs forward: timing affects price
The same credit can fetch a different price depending on when you sell it. Forward offtakes typically price a little lower (often ~$80–110/tCO₂e as of June 2026) because the buyer is committing early and taking on delivery risk — but that commitment can finance the project. Spot sales can capture more, with more market risk. We cover the trade-off in How to Sell Biochar Carbon Credits.
Why India can be price-competitive
India's advantage is cost of production, not a discount on integrity. Abundant, sustainable genuine-waste biomass and competitive conversion costs mean Indian projects can produce durable removals at attractive economics — and still command quality pricing if the MRV and permanence are strong. The goal is never to be the cheapest tonne; it's to be a high-integrity tonne produced efficiently.
Will prices rise or fall?
Direction is genuinely uncertain, so build your model on conservative estimates. On the demand side, large corporates continue to contract durable removals (for example, reported deals by Google and Microsoft for biochar through 2029–2030 — figures to verify). On the supply side, more projects are coming online, which can soften prices. Net direction depends on which moves faster. Any forecast is a scenario to pressure-test, not a promise.
How to maximise your price per tonne
- Engineer permanence in — choose technology that hits a low H/Corg.
- Invest in MRV early — conservative, digital, audit-ready data.
- Keep feedstock clean — sustainable, traceable, genuine waste.
- De-risk delivery — credible volumes and schedules buyers can count on.
- Tell a true co-benefit story — measured soil and livelihood gains, not claims.
Each of these is something we help projects get right before they go to market.
Get a project-specific estimate
Generic ranges only go so far. To get an estimate grounded in your feedstock, technology and target buyers, request a feasibility assessment — we model time-stamped, clearly-labelled estimates, never guarantees.
