A pile of palm kernel shells smoking behind a mill is, today, just a disposal problem. The question worth asking is what that same pile is worth if you treat it differently. Not the vague promise of "carbon money," but the actual number. So here it is, the real 2026 price of a biochar carbon credit, why it swings so wildly, and what it means for a factory sitting on tonnes of plant waste.
The headline number
A biochar carbon credit, one tonne of carbon dioxide kept out of the sky, sells for roughly €105 to €200 in 2026, depending on where and how it is made. The average across the market in 2025 landed around $164 per tonne, up about a quarter from $131 just two years earlier. The trend is up, and the reason is simple: more companies need to remove carbon, and there is not enough good supply to go around.
Now here is the part that turns a number into a business. One tonne of biochar does not lock away one tonne of CO2. It locks away two to three tonnes. So a few thousand tonnes of shell a year, turned into biochar, can become several thousand tonnes of carbon removal, and at these prices, that is hundreds of thousands of dollars of carbon value sitting in waste you used to burn.
The waste is not worthless. It is unpriced.
Why the price swings so much
A €100 gap between the cheap end and the expensive end is enormous. It comes down to a few things, and they are worth understanding because some of them are in your control.
- Feedstock and region. Industrial biochar from Bolivia clusters around €160 to €180. German biochar sells for €189 to €200. Indian biochar, the cheapest, starts near €105. Same product, very different price, partly because buyers pay more for credits from places they consider low-risk.
- Permanence. Char that proves it will last centuries earns more than char that might not. Quality is rewarded.
- Traceability. The cleaner your paper trail, the more a serious buyer will pay, because they have to defend the purchase to their own auditors.
The catch worth knowing
Geography cuts against us here, and it is honest to say so. A buyer may pay less for an African credit than an identical German one, purely on perceived country risk. The answer is not to complain about it. It is to make the rest of the package, the permanence, the traceability, the sustainability story, so clean that the credit stands on its own. That is a thing you can control.
The number that matters more than the price
Here is the fact that confuses almost everyone, and it is the most important one on this page.
In 2025, the average carbon credit sold on the open "spot" market for about €6. The average credit sold through a long-term "offtake" contract sold for about €180. Same year. Same idea of a tonne of CO2. Thirty times the price.
How is that possible? Because they are not really the same product. The cheap €6 world is full of old, low-quality, "we avoided some emissions" credits that serious buyers no longer trust. The expensive €180 world is durable removal, biochar and its cousins, bought by companies that need the real thing and are willing to pay for it.
Biochar lives in the expensive world. But you only reach that world through a contract, not a shop.
This is why you cannot just "list your credits and wait." The good money is not on a public exchange. It is in direct, multi-year deals between a project and a buyer.
Who is actually buying
Follow the money and it leads to a surprisingly small room. A handful of giant companies, Microsoft, Google, JPMorgan, Swiss Re, account for most of the durable carbon removal bought on the planet. Microsoft alone makes up around three quarters of all the big removal deals on Earth.
These buyers behave in three ways that matter to you:
- They pre-buy. They sign offtake deals for years of future credits rather than buying what already exists. By late 2025, more than 90% of available industrial biochar supply was already locked up this way.
- They are picky, not cheap. Within the €100 to €500 range, price barely moves them. What moves them is quality: permanence, honesty, a clean audit trail.
- They buy from people they trust. These are deep, due-diligence-heavy relationships, not transactions.
The catch
This concentration is a double-edged sword. It means demand is strong and prices hold firm, which is good. But it also means the market leans heavily on a few buyers, and reaching them is hard if you are new and unknown. A certified credit with no buyer relationship is a cheque you cannot cash. The carbon is the easy part. The access is the hard part.
What this means for a West African mill
Put it together and the picture is genuinely good for a processor here, with one condition.
The good: you sit on exactly the feedstock this market is starving for. Supply is tight, demand is rising, and biochar is the proven, ready-now option that big buyers already trust. Your shells and sawdust are on the right side of this market.
The condition: the value only becomes real money when the credit is verified to a high standard and connected to a buyer who will pay the €180 price, not the €6 one. Both of those, the verification and the access, are work. They are exactly the work that decides whether your waste earns six dollars a tonne of CO2 or a hundred and sixty.
That gap, between the cheap market and the real one, is the whole game. It is also the reason we exist.
Biochar Industrial Group turns the waste you already produce into verified biochar credits and connects them to the buyers who pay the high price. We handle the certification, the quality, and the relationships, the parts that move a credit from the €6 shelf to the €180 contract. You bring the waste. We turn it into carbon revenue.
If you are burning plant waste every week, the first step is just knowing what it is worth.
