Why biochar is becoming the fastest-to-market CDR pathway in emerging carbon markets
Biochar sits in the “engineered durable CDR” bucket, and that matters because it can reach issuance faster than many nature-based pathways. Under programs such as Puro.earth, credits are issued ex-post, meaning removals are measured and third-party verified before credits are minted. That structure reduces over-crediting risk and tends to fit conservative buyer policies better than ex-ante approaches.
Biochar has also become a volume leader inside durable CDR. Puro.earth highlights rapid growth in biochar issuance over recent years and a dominant role for biochar within verified durable removal volumes. For buyers, this is the difference between a one-off pilot and a pathway that can support multi-year procurement with repeatable project types.
Price discovery is clearer in biochar than in many other removal categories. Puro.earth references a public index for biochar CORCs, Nasdaq’s CORCCHAR, with 2025 average prices typically around $125 to $145 per tCO₂. Prices are usually higher than avoidance credits because buyers are paying for durability, tighter MRV, and the ex-post issuance model, not just a climate claim.
Biochar is “fast-to-market” in emerging carbon markets for practical reasons, not because MRV is easy. Plants can be small to mid-scale and deployed modularly, agricultural residues are widely available, and some systems can produce useful energy co-products. The real bottleneck is MRV: feedstock traceability, sampling plans, lab testing, and lifecycle accounting often determine how quickly a project can move from commissioning to verified issuance.
Procurement teams increasingly treat biochar as a near-term delivery option. Spot purchases can cover immediate needs, while forward contracts can be structured around milestones such as commissioning, ramp-up, and audit completion. Planet2050 notes that deliverability and pricing depend heavily on vintage and certainty of delivery, so “cheap forward” can become expensive if issuance slips.
If biochar is the most commercialisable durable CDR pathway today, the next procurement question is simple: why Colombia now? Feedstock availability, operating costs, and MRV execution will decide whether Colombian supply becomes a reliable part of buyer portfolios.
Colombia’s entry point: feedstocks, project economics, and MRV requirements that matter to buyers
Colombia has now seen the first issuance of biochar-based CDR credits, framed as part of a regional expansion beyond a prior stronghold in Bolivia. Carbon Pulse reported this as a milestone that signals both pipeline development and an intent to replicate operating models across borders.
Feedstock is the first buyer-relevant variable in Colombia. Agricultural and agro-industrial residues can include materials linked to palm, coffee, sugarcane, rice, and forestry residues, among others. Buyers should treat feedstock as a core input to credit quality and cost, not a footnote. The right questions are operational: are there binding feedstock supply contracts, what is the seasonality, what are moisture and contamination ranges, and what is the average logistics distance from residue source to plant.
Project economics are usually “dual revenue” by design. Developers can sell biochar into soil or industrial markets and also sell carbon removal credits. In many cases, credit revenue is a meaningful part of the margin, which makes the credit price level and issuance cadence commercially decisive. Sensitivities tend to cluster around yield (biochar per tonne of feedstock), carbon content and stability, process energy, and inbound and outbound logistics. The CORCCHAR price range discussed by Puro.earth helps buyers benchmark whether a project’s economics look plausible, but it does not replace diligence on the project’s own cost curve.
MRV is where buyers can separate “a plant that makes biochar” from “a project that reliably issues high-integrity removals.” Puro-style requirements emphasise chain-of-custody for feedstock, lab measurement of biochar properties, and lifecycle assessment for process emissions, with third-party verification before issuance. Senken’s overview of Puro.earth underlines that ex-post issuance is central to the crediting logic, and buyers should expect to see an audit statement and supporting documentation in the registry.
Forward procurement in Colombia needs contract language that reflects the difference between physical production and registry issuance. Delivery schedules should be defined by vintage and issuance conditions, not just by expected production months. Substitution and make-good clauses matter because a project can produce biochar but still miss issuance timing if sampling, lab work, or verification runs late.
Once buyers understand how Colombian supply is built, the next question becomes replicability. Standards can travel, but datasets, permits, and Article 6 authorisations do not move as easily across borders.
The regional expansion playbook: how standards scale from Bolivia to Colombia and what changes across borders
Scaling across Latin America often follows a repeatable pattern: replicate plant design, replicate MRV processes, and secure offtake. Keeping the same certification standard across multiple countries reduces buyer due diligence costs and makes credits easier to hold as a coherent portfolio, because the claim type and durability framing remain comparable. Senken’s Puro.earth materials are useful here because they show how a standardised approach can anchor buyer confidence even when projects sit in different jurisdictions.
What changes across borders is mostly the input data and the operating context. Feedstock mix affects carbon yield and logistics emissions. Grid emission factors and fuel choices change the lifecycle footprint. Permitting can impose different constraints on air emissions and monitoring. Social and land tenure risks can show up in residue supply chains, especially when residues have competing uses or when sourcing practices are informal. All of these factors can shift net removals and reputational risk, even if the methodology is the same.
MRV requirements are portable, but MRV evidence is not. Buyers should ask for an MRV pack that is comparable project-to-project: mass balance, sampling plan, QA/QC procedures, lab methods, and LCA assumptions. That comparability is what allows procurement teams to evaluate Colombia versus Bolivia or other supply corridors without relying on marketing narratives.
Integrity expectations for biochar are also converging upward. Puro.earth has discussed cross-standard learnings on permanence and conservative approaches, which supports a practical point for buyers: regional scaling does not have to mean a race to the bottom. It can mean more consistent rules, clearer durability framing, and better documentation norms.
Tokenisation and digital market infrastructure become more relevant as supply scales. Serialisation, digital MRV records, and registry-to-portfolio integrations can reduce operational friction for buyers managing many deliveries. The caution is “wrapping risk”: a token or digital wrapper is not the same as retirement, and buyers still need controls that prove title, current registry status, and that retirement happens in the underlying registry.
If standards and pipelines scale, the buyer’s core question remains unchanged: are these credits durable and high-integrity? That comes down to permanence, leakage, additionality, and how co-benefits are treated.
Integrity and durability checks: permanence, leakage, additionality, and co-benefits in biochar crediting
Durability is the headline claim for biochar, but buyers should look at how durability is labelled and how conservative the standard is. Puro.earth has discussed updated framing such as CORC200+ for “several centuries,” stepping away from premature millennium-scale claims. This matters for internal buyer policies that map removals to “like-for-like” durability tiers and define what qualifies for long-lived emissions.
Leakage and baseline questions in biochar are often about residues, not land. The common risk is displacement: if a residue already had a low-emission use, diverting it to pyrolysis can create indirect emissions elsewhere. Transport can also become a material emissions source if feedstock is hauled long distances. Buyers should ask for evidence of local common practice and competing uses, plus how the project’s baseline treats those uses.
Additionality still needs to be argued, even with ex-post issuance. Ex-post reduces the risk of issuing credits for removals that never happened, but it does not prove that the project required carbon revenue to proceed. Practical additionality checks include financial barrier analysis, IRR with and without credit revenue, evidence of financing constraints, and the role of secured feedstock contracts. Registry documentation, including additionality reporting and the verification statement, is where buyers should anchor this assessment, as illustrated by the type of documentation accessible through Puro.earth’s registry project pages.
Biochar quality MRV is not just a lab certificate. Buyers should look for carbon content measurement, stability proxies such as H/Corg, chain-of-custody controls, and a defensible sampling plan. Methodologies can evolve as science and standard practice change, so versioning matters. Buyers should confirm which methodology version was applied and whether conservative defaults were used, especially where local data is limited.
Co-benefits can be real, but they should be treated as secondary claims. Soil improvement, yield impacts, and reduced open burning are often discussed in the region, but they need evidence such as trials and monitoring. They should never be used to compensate for weak carbon accounting.
After filtering for integrity, procurement teams face the commercial question: what will the market pay, and what demand signals will support liquidity for multi-year contracting?
Pricing and demand outlook: how corporate procurement and CORSIA/Article 6 signals could shape liquidity
The most useful pricing anchor for buyers is the existence of a public biochar index. Puro.earth points to Nasdaq’s CORCCHAR, with 2025 average prices typically around $125 to $145 per tCO₂. That range can act as a reference point for “base quality” durable biochar removals, while premiums often reflect ready delivery, stronger MRV documentation, a preferred durability label, verifier reputation, and tighter offtake terms. Spot and retail offers can price higher, especially when supply is scarce or delivery is immediate.
Corporate demand for biochar and durable CDR has been growing, including through publicly disclosed purchases and contracting activity. Senken’s biochar materials point to expanding procurement interest, which matters for buyers assessing liquidity risk. Liquidity in removals is still thin compared to avoidance markets, but biochar is one of the few categories where repeatable issuance and clearer pricing references can support multi-year planning.
Compliance-linked demand could reshape pricing, but it comes with conditions. Under CORSIA, eligibility depends on program and credit requirements, and for Article 6-aligned use buyers will look for host country authorisation and corresponding adjustments to avoid double claiming. Verra’s CORSIA information is a useful reminder that “VCM-ready” and “CORSIA-ready” are not the same product, and that difference can create a pricing wedge.
Policy optionality is becoming a contract feature, not a talking point. Many buyers procure today for voluntary claims but want the option to upgrade if Article 6 pathways open. Contracts can include a right to upgrade or convert, representations and warranties on host country authorisation efforts, and a fallback if a letter of authorisation does not arrive by a defined date.
Regulatory signals outside the region can still influence global demand. The EU has moved toward a certification framework for carbon removals that includes biochar, which can reinforce demand for removals that meet clearer certification expectations. For global buyers, this is less about one market and more about standardisation pressure that can lift documentation norms across suppliers.
With pricing and demand drivers clearer, execution becomes the differentiator. Buyers and developers need procurement mechanics that manage delivery risk, especially in newer supply corridors such as Colombia.
What developers and buyers should do next: due diligence questions, contracting terms, and delivery risk management
Buyers should ask for an investment-grade due diligence pack and treat missing documents as a risk signal. A practical minimum set includes the applied methodology and version, the VVB audit statement, LCA assumptions and boundaries, mass balance and sampling documentation, feedstock contracts, proof of title and current registry status, and any rules on reversals and buffers if applicable. Senken’s Puro.earth overview is a good checklist prompt because it reflects how ex-post issuance and verification are operationalised.
Buyers evaluating Colombia and broader Latin America should run a technical question set that maps directly to credit quality. Key topics include competing uses and leakage risk for each feedstock, real operating capacity versus nameplate, process energy sources (grid versus onsite syngas or other fuels), the sampling plan and lab competence, and contaminant management tied to end-use requirements for the biochar.
Offtake contracts work best when they separate governance from delivery. A common structure is a master agreement plus annual delivery schedules, with clear definitions for vintage, delivery windows, and delivery location as registry transfer. Make-good and true-up clauses should be explicit, and remedies for audit delays should be practical. The goal is to avoid a mismatch where physical production happens but issuance timing does not.
Delivery risk management should be staged, not binary. Many buyers start with ex-post spot purchases to validate MRV and operational performance, then increase forward exposure with milestone-based payments and step-in rights. Covenants tied to commissioning, feedstock continuity, and MRV KPIs such as audit timelines and non-conformities can reduce surprises.
Article 6 and CORSIA readiness should be priced and contracted as optionality, not assumed. If a buyer wants compliance optionality, contracts can require the developer to pursue host country authorisation and corresponding adjustment pathways, with price adjustments or termination rights if authorisation is not obtained by agreed dates. Ceezer’s discussion of CORSIA integrity highlights why these terms matter in practice.
Developers can “sell the risk out” by making diligence easy. Publishing a consistent MRV pack, standardising reporting across countries, and using robust digital processes for MRV records and registry operations can reduce friction with institutional buyers. Buyers, in turn, can build a Latin America scorecard that compares Colombia, Bolivia, and other corridors on the same variables: feedstock risk, net removal sensitivity, MRV maturity, issuance track record, and contract enforceability.
