What Exomad Green and Supercritical Actually Agreed and Why the Scale Matters
The key signal is not just the headline volume. It is the fact that Exomad Green announced a multi-year carbon removal agreement with Supercritical for 130,000 tonnes of biochar carbon removal in 2025, while saying 62% of its 2025 supply was already committed and 30% of 2026 was already booked. That is what makes this a serious biochar offtake agreement, not just another announcement.
The scale matters because it shows durable CDR supply being reserved ahead of delivery in a market that is still relatively illiquid. Exomad also said it was moving from 86,000 tonnes in 2024 to 210,000 tonnes in 2025, which tells buyers and procurement teams that this is industrial-scale carbon removal, not a one-off batch.
For corporate buyers, the point is simple. A multi-year carbon removal contract is not only about buying credits. It is about locking in output, stabilising the pipeline, and reducing the risk of missing 2030 targets because supply is unavailable when needed. In other words, this is tonnage commitment as procurement strategy.
That is why the scale matters more than the exact headline number. In a market where durable CDR supply is still tight, reserving future capacity can be more important than chasing spot availability. Once that is clear, the next question is why biochar is becoming a more bankable CDR category than many other removal pathways.
Why Biochar Is Emerging as a Bankable CDR Category for Corporate Buyers
Biochar is becoming a bankable CDR category because it is already delivering most of the market’s durable removals. In 2024, biochar accounted for 86% of global durable CDR deliveries, according to CDR.fyi. That is a strong sign of commercial maturity compared with technologies that are still pre-commercial or early-stage.
Quality signals matter here too. Exomad said in May 2025 that it had reached an organic carbon content of 86.3%, which is relevant for durability, MRV, and methodological consistency. For buyers, that kind of benchmark helps turn biochar credits into something closer to a high-integrity carbon removals product rather than a speculative future supply.
Biochar also fits procurement better than some other pathways. It is modular, plants can be scaled in steps, and production timelines are generally shorter than DAC or BECCS. That makes it suitable for delivery-backed procurement, staggered buying, and multi-year planning. Buyers do not need to wait for a single giant facility to come online before they can contract supply.
This is why terms like durable carbon removal, biochar credits, MRV, and high-integrity carbon removals are showing up more often in buyer conversations. If biochar is easier to finance and deliver, then the next issue is how this fits into the post-Microsoft demand reset in carbon removal.
How This Deal Fits Into the Post-Microsoft Demand Reset in Carbon Removal
The Microsoft effect needs to be framed carefully. Microsoft continued buying very large volumes of CDR in 2025, but the market is increasingly reading those announcements as normalisation of demand rather than endless linear growth. The signal is still strong, but it is no longer the whole market story.
The market data supports that reset. CDR.fyi says the biochar carbon removal market grew from $14.6 million in 2022 to $33.9 million in 2023 and $181.5 million in 2024, with the Microsoft-Exomad agreement for 1.24 million tonnes weighing heavily on 2025 growth. That means one mega deal can still dominate the numbers, but it does not mean demand is disappearing when the pace changes.
Corporate demand is also becoming more selective. Buyers are no longer chasing only headline deals. They want a mix of pricing, durability, delivery schedule, and supply chain assurance. That is the real post-Microsoft demand reset in the durable CDR market.
For procurement teams, this changes the buying logic. The question is not simply whether to buy CDR. It is which pathway, at what price, with what delivery profile, and under what counterparty risk. That leads directly to the contract structure behind these deals.
What the Agreement Reveals About Offtake Structures, Pricing, and Delivery Risk
The commercial structure matters as much as the volume. In durable CDR, multi-year contracts help de-risk CAPEX and working capital for developers, which is why offtake pricing and delivery risk are central to the deal. A buyer is not just purchasing removals. It is helping finance future supply.
Market plumbing is improving too. CDR.fyi reports that the time between issuance and first transfer or retirement of a biochar CORC fell from 95 days in 2021 to 22 days by mid-June 2025. That suggests a more efficient market infrastructure and better settlement flow.
For buyers, the practical questions are straightforward. How are milestones handled? Is there a pre-purchase agreement? Are there delivery tranches? What happens if there is underdelivery, slippage, or a feedstock quality issue? These are the clauses that decide whether a contract is financeable and enforceable.
That is why terms like milestone-based contract, removal delivery schedule, counterparty risk, and MRV-linked settlement matter so much. If the contract is sophisticated, then the supply chain behind it becomes the real differentiator. In this case, that means the biomass and forest residues feeding the plants in Bolivia.
Why Supply from Forest Residues in Bolivia Could Attract International Buyers
Residue-based feedstock is a major advantage. Exomad says it turns forest residues into biochar through two active plants, with a third under development in 2026, and it has said it aims to remove 260,000 tonnes of CO₂ per year. That gives buyers a supply story built around circular carbon management rather than land-intensive feedstock competition.
For international buyers and traders, residue-based feedstock can be easier to diligence than other biomass sources. It can offer better traceability, less competition with food uses, and a stronger case for chain-of-custody controls. Those are important proof points when buyers are assessing ESG risk alongside tonnage.
Due diligence still matters. Buyers will want sourcing monitoring, land-use integrity, community impact, upstream emissions control, and clear chain-of-custody documentation. They will also want to understand how additionality and leakage are addressed, especially when the project is scaling quickly.
Exomad has also said it wants to reach 1 MtCO₂ per year by 2027. That is a meaningful signal because it points to an export-oriented carbon removal hub rather than a niche project. If a regional supply base can scale with quality and compliance, then the next phase is not just more Big Tech demand. It is a broader buyer base.
What This Means for the Next Phase of CDR Market Growth, Beyond Big Tech
The next phase of CDR market growth is about market expansion, not just mega buyers. Microsoft and Google helped validate the market, but the real test now is whether mid-market corporates, financial buyers, and portfolio builders can keep demand growing.
Biochar has led durable CDR growth in 2025, but the market is also showing more diversity in sectors, volumes, and contract structures. That matters because a mature market cannot depend on a single anchor buyer forever. It needs a corporate demand pipeline that is broader and more repeatable.
For buyers, the message is practical. Procurement discipline now matters more than brand prestige. Robust contracts, reliable delivery, and credible MRV are becoming the real filters. That is what makes the next phase of CDR market growth different from the first wave.
The strongest conclusion is also the simplest. A mega offtake in biochar is not an exception. It is a sign that durable removals are becoming purchasable, financeable, and repeatable beyond the big tech carbon removal playbook.
