This blog breaks down the science of biochar's carbon stability, compares it against other carbon removal pathways, and explains what durability ratings mean for carbon credit buyers. Agricultural businesses, textile brands, and corporate sustainability teams will find clear answers on whether biochar fits their climate strategy.","\n\u003Cp>Carbon removal is only as valuable as how long the carbon stays removed. That single principle is reshaping how buyers, brands, and policymakers evaluate every climate solution on the market today — and it is the reason \u003Cstrong>biochar carbon removal\u003C\u002Fstrong> is drawing serious attention from agricultural businesses, textile supply chains, and corporate sustainability teams alike.\u003C\u002Fp>\n\n\u003Cp>Biochar is not new. Farmers in the Amazon basin were enriching soils with charred organic matter thousands of years ago. What is new is the rigorous science around its carbon stability, the emergence of verified credit markets, and the growing recognition that biochar occupies a genuinely rare position: a nature-based carbon removal method with near-engineered durability. This post breaks down what that means in practice, how biochar compares to competing pathways, and which organisations should be building it into their climate strategy right now.\u003C\u002Fp>\n\n\u003Cimg src=\"https:\u002F\u002Fimages.beetleregen.com\u002Fblogs\u002Fonnzzz0zi2rx08czq2uydvpzi-content-0-67a4de98.webp\" alt=\"South Asian farmer holding dark porous biochar in hands with a cotton field in the background\">\n\n\u003Ch2>The Durability Problem at the Heart of Carbon Removal\u003C\u002Fh2>\n\n\u003Cp>Not all carbon sequestration is created equal. A tree planted today sequesters carbon for as long as it stands — but it can burn, be felled, or die within decades. Soil organic carbon (SOC) builds slowly and can be released back into the atmosphere through tillage, drought, or land-use change. Even the most carefully managed nature-based projects carry a fundamental risk: the carbon they store is biologically active and reversible.\u003C\u002Fp>\n\n\u003Cp>This is the durability problem. For a carbon removal claim to support a credible net zero target, the carbon must stay out of the atmosphere for a timeframe that is meaningful relative to the climate crisis. Most scientists and standard-setting bodies use 100 years as the minimum threshold for \"permanent\" removal. Some frameworks, particularly those aligned with the \u003Ca href=\"https:\u002F\u002Fwww.ipcc.ch\u002Freport\u002Far6\u002Fwg1\u002F\" target=\"_blank\" rel=\"noopener noreferrer\">IPCC Sixth Assessment Report\u003C\u002Fa>, push that threshold further, arguing that truly durable removal should be measured in centuries, not decades.\u003C\u002Fp>\n\n\u003Cp>This is where the carbon removal landscape splits into two broad camps. On one side are \u003Cstrong>biologically mediated pathways\u003C\u002Fstrong> — reforestation, soil carbon, wetland restoration, that offer significant co-benefits but carry inherent reversal risk. On the other are \u003Cstrong>engineered pathways\u003C\u002Fstrong>, direct air capture (DAC), bioenergy with carbon capture and storage (BECCS), that offer high permanence but at enormous cost and energy intensity. Biochar sits at the intersection of both worlds, and that positioning is precisely what makes it worth understanding carefully.\u003C\u002Fp>\n\n\u003Ch2>What Is Biochar Carbon Removal, Exactly?\u003C\u002Fh2>\n\n\u003Cp>Biochar is produced through \u003Cstrong>pyrolysis\u003C\u002Fstrong>, the thermal decomposition of organic biomass in a low-oxygen or oxygen-free environment at temperatures typically between 350°C and 700°C. The process converts carbon that would otherwise decompose and return to the atmosphere (as CO₂ or methane) into a highly stable, aromatic carbon structure. That structure is what gives biochar its durability.\u003C\u002Fp>\n\n\u003Cp> \u003Cstrong>Cotton stalks, rice husks, wheat straw, and sugarcane bagasse\u003C\u002Fstrong> are all viable feedstocks, agricultural residues that are often burned in the field or left to decompose. Converting these residues into biochar instead of burning them prevents the immediate release of CO₂ and methane, while simultaneously creating a carbon-rich soil amendment.\u003C\u002Fp>\n\n\u003Cp>It is important to distinguish between two roles biochar plays. As a \u003Cstrong>soil amendment\u003C\u002Fstrong>, biochar improves water retention, cation exchange capacity, and microbial activity, benefits that are well-documented in Indian cotton farming contexts. As a \u003Cstrong>carbon removal tool\u003C\u002Fstrong>, biochar's value lies in the stability of the carbon it locks away. Both roles matter, but they are measured and verified differently. Carbon credit programs focus on the latter: how much carbon is durably sequestered, for how long, and with what degree of certainty.\u003C\u002Fp>\n\n\u003Cp>For a deeper look at how biochar functions as a soil health tool specifically in Indian cotton farming, see our earlier analysis on biochar benefits for soil carbon in Indian cotton farming. This post focuses on the carbon removal and durability dimensions that matter most for credit buyers and sustainability strategists.\u003C\u002Fp>\n\n\u003Ch2>How Durable Is Biochar Carbon, Really?\u003C\u002Fh2>\n\n\u003Cp>The scientific consensus on biochar's carbon stability is more robust than for almost any other nature-based carbon removal pathway. Studies consistently show a \u003Cstrong>mean residence time (MRT) of 100 to over 1,000 years\u003C\u002Fstrong> for biochar carbon in soil, depending on production conditions and the environment where it is applied. A landmark meta-analysis published in \u003Cem>Nature Communications\u003C\u002Fem> estimated a mean half-life of approximately 556 years for biochar carbon under typical soil conditions.\u003C\u002Fp>\n\n\u003Cp>Three factors primarily determine where on that spectrum a given biochar falls:\u003C\u002Fp>\n\n\u003Cul>\n  \u003Cli>\u003Cstrong>Pyrolysis temperature:\u003C\u002Fstrong> Higher temperatures (above 500°C) produce biochar with a more condensed aromatic structure and greater resistance to microbial decomposition. Lower-temperature biochars retain more labile carbon fractions that can degrade more quickly.\u003C\u002Fli>\n  \u003Cli>\u003Cstrong>Feedstock type:\u003C\u002Fstrong> Woody feedstocks and crop residues with high lignin content tend to produce more stable biochar than feedstocks with high nitrogen or moisture content.\u003C\u002Fli>\n  \u003Cli>\u003Cstrong>Soil and climate conditions:\u003C\u002Fstrong> Biochar degrades more slowly in cool, dry soils than in hot, humid tropical environments. This is a relevant consideration for programs operating in South Asia.\u003C\u002Fli>\n\u003C\u002Ful>\n\n\u003Cp>The most widely used proxy for biochar stability is the \u003Cstrong>H:Corg ratio\u003C\u002Fstrong> (the molar ratio of hydrogen to organic carbon). Both the \u003Ca href=\"https:\u002F\u002Fwww.european-biochar.org\u002Fen\u002Fhome\" target=\"_blank\" rel=\"noopener noreferrer\">European Biochar Certificate (EBC)\u003C\u002Fa> and the International Biochar Initiative (IBI) use this ratio as a quality threshold. Biochar with an H:Corg ratio below 0.7 is classified as stable; below 0.4 is considered highly stable. This gives buyers and verifiers a measurable, reproducible indicator of durability that does not require waiting centuries to confirm.\u003C\u002Fp>\n\n\u003Cp>Compare this to soil organic carbon, where stability depends on complex interactions between soil minerals, microbial communities, and land management, factors that are difficult to measure and even harder to guarantee over time. Biochar's chemical stability is, in this sense, more predictable and more defensible as a carbon removal claim.\u003C\u002Fp>\n\n\u003Ch2>Biochar vs. Other Carbon Removal Pathways: A Durability Comparison\u003C\u002Fh2>\n\n\u003Cp>To understand where biochar fits in a climate strategy, it helps to place it alongside the other pathways that corporate buyers and sustainability teams are evaluating. The table below summarises the key dimensions that matter for carbon credit buyers: durability, cost, co-benefits, and verification complexity.\u003C\u002Fp>\n\n\u003Cimg src=\"https:\u002F\u002Fimages.beetleregen.com\u002Fblogs\u002Fonnzzz0zi2rx08czq2uydvpzi-content-1-6e8fdc16.webp\" alt=\"Comparison illustration of carbon removal pathways from short-lived reforestation and soil carbon to long-lived biochar and engineered direct air capture\">\n\n\u003Ch3>Soil Organic Carbon (SOC)\u003C\u002Fh3>\n\u003Cp>\u003Cstrong>Durability:\u003C\u002Fstrong> 10, 100 years (highly variable). \u003Cstrong>Cost per tonne CO₂:\u003C\u002Fstrong> USD 10, 50. \u003Cstrong>Co-benefits:\u003C\u002Fstrong> Significant, improved soil fertility, water retention, biodiversity. \u003Cstrong>Verification complexity:\u003C\u002Fstrong> High.

It offers durability that is an order of magnitude greater than most nature-based solutions, at a cost that is significantly lower than engineered removal. It also generates measurable co-benefits, particularly soil health improvements, that make it attractive for agricultural supply chains where soil degradation is already a pressing problem. For a broader view of how carbon sequestration methods compare within agricultural systems, the carbon sequestration in agriculture framework provides useful context.\u003C\u002Fp>\n\n\u003Cp>The honest limitation is cost. At USD 50, 200 per tonne, biochar credits are more expensive than soil carbon or reforestation credits. For buyers who need large volumes at low cost, biochar alone will not be sufficient. But for buyers who need \u003Cem>verifiable, durable\u003C\u002Fem> removal to underpin a net zero claim, particularly for residual emissions that cannot be eliminated, biochar's durability premium is often worth paying.\u003C\u002Fp>\n\n\u003Ch2>What Durability Ratings Mean for Carbon Credit Buyers\u003C\u002Fh2>\n\n\u003Cp>The carbon credit market has developed specific frameworks for classifying and pricing durability. Understanding these frameworks is essential for any organisation purchasing biochar credits as part of a net zero or carbon neutral strategy.\u003C\u002Fp>\n\n\u003Ch3>How Standards Bodies Classify Biochar Durability\u003C\u002Fh3>\n\n\u003Cp>\u003Cstrong>Puro.earth\u003C\u002Fstrong>, one of the leading marketplaces for engineered carbon removal, classifies biochar as a \"durable\" removal pathway and applies a minimum 100-year durability requirement. Their methodology requires producers to demonstrate H:Corg ratios below 0.7 and to document pyrolysis conditions for each batch. Credits are issued on a per-tonne basis with full traceability to the production event.\u003C\u002Fp>\n\n\u003Cp>\u003Cstrong>Verra's Verified Carbon Standard (VCS)\u003C\u002Fstrong> has developed the VM0044 methodology specifically for biochar. It includes permanence buffers, a percentage of credits withheld in a pooled buffer account to cover potential reversal risk, though these buffers are typically lower for biochar than for soil carbon or reforestation, reflecting biochar's greater chemical stability.\u003C\u002Fp>\n\n\u003Cp>\u003Cstrong>Gold Standard\u003C\u002Fstrong> also accepts biochar projects under its Land Use and Forests framework, with similar requirements around feedstock documentation, production monitoring, and application records.\u003C\u002Fp>\n\n\u003Ch3>Permanence Buffers and Discount Factors\u003C\u002Fh3>\n\n\u003Cp>Even for high-durability pathways, most standards apply some form of permanence discount. For biochar, this typically ranges from \u003Cstrong>5, 15%\u003C\u002Fstrong> of credits issued, compared to 20, 40% for soil carbon projects. This means that for every 100 tonnes of CO₂ sequestered in biochar, a buyer might receive 85, 95 verified credits. Understanding this discount is important when comparing biochar credits to other removal types on a cost-per-verified-tonne basis.\u003C\u002Fp>\n\n\u003Ch3>What the 100-Year Threshold Means for Net Zero Claims\u003C\u002Fh3>\n\n\u003Cp>The Science Based Targets initiative (SBTi) and most credible net zero frameworks require that carbon removal used to neutralise residual emissions must be \"permanent\", defined as lasting at least 100 years. Biochar meets this threshold under all major standards. Soil organic carbon, by contrast, often does not qualify for residual emission neutralisation under the strictest interpretations of SBTi guidance, because its reversibility risk is too high.\u003C\u002Fp>\n\n\u003Cp>This distinction matters enormously for corporate sustainability teams. If your organisation has committed to a net zero target that includes neutralising residual emissions, the type of carbon removal you purchase is not interchangeable. Biochar credits, with their verified 100+ year durability, are among the few nature-adjacent options that can legitimately support that claim. For brands navigating this landscape, the fashion brand net zero roadmap offers a practical framework for structuring these decisions.\u003C\u002Fp>\n\n\u003Ch2>Biochar Carbon Removal in Textile Supply Chains: A Practical Fit?\u003C\u002Fh2>\n\n\u003Cp>For textile and fashion brands, biochar carbon removal is not just a credit-purchasing exercise. It can be integrated directly into the agricultural supply chain as a form of \u003Cstrong>carbon insetting\u003C\u002Fstrong>, reducing and removing emissions within the value chain rather than purchasing offsets from unrelated projects.\u003C\u002Fp>\n\n\u003Ch3>Cotton Stalks as Feedstock: Closing the Loop\u003C\u002Fh3>\n\n\u003Cp>Cotton farming generates significant quantities of crop residue, primarily cotton stalks, that are typically burned in the field after harvest. Field burning is a major source of black carbon, CO₂, and particulate emissions in cotton-growing regions of India and Bangladesh. Converting these stalks into biochar through on-farm or community-level pyrolysis units transforms a waste stream into a carbon removal asset.\u003C\u002Fp>\n\n\u003Cp>This circular logic is compelling for brands. The same cotton supply chain that generates the residue also benefits from the biochar when it is applied back to the soil, improving water retention, reducing fertiliser requirements, and supporting the soil health outcomes that regenerative agriculture programs are designed to deliver. The carbon removal is embedded in the supply chain, not purchased from a distant project with no connection to the brand's actual footprint.\u003C\u002Fp>\n\n\u003Ch3>Biochar's Dual Role in Regenerative Cotton Programs\u003C\u002Fh3>\n\n\u003Cp>Beetle Regen's biochar-based carbon insetting programs in India are designed around exactly this logic. Farmers in the program convert cotton stalk residue into biochar using controlled pyrolysis, apply it to their fields, and generate verified carbon removal credits in the process. The credits are attributed to the brand's supply chain, supporting Scope 3 emission reduction claims. The soil benefits, improved organic matter, better water-holding capacity, reduced input costs, accrue directly to the farmers, strengthening the economic case for adoption.\u003C\u002Fp>\n\n\u003Cp>This approach aligns with the broader principles of \u003Ca href=\"https:\u002F\u002Fbeetleregen.com\u002Farticle\">carbon insetting for textile supply chains\u003C\u002Fa>, where the goal is not just to neutralise emissions on paper but to build climate resilience into the supply chain itself. It also connects to the soil health outcomes that brands increasingly need to demonstrate to investors and regulators, outcomes that soil carbon alone cannot reliably deliver at scale.\u003C\u002Fp>\n\n\u003Cp>For brands exploring how traceability systems can support biochar verification within a cotton supply chain, the MRV and traceability systems guide for cotton provides a detailed operational framework.\u003C\u002Fp>\n\n\u003Ch2>Verification and MRV: The Credibility Layer Biochar Needs\u003C\u002Fh2>\n\n\u003Cp>Biochar's chemical stability is its greatest asset. But stability alone does not make a carbon credit credible. The credibility comes from \u003Cstrong>measurement, reporting, and verification (MRV)\u003C\u002Fstrong>, the documentation trail that connects a specific batch of biochar to a specific carbon removal claim.\u003C\u002Fp>\n\n\u003Ch3>What Robust Biochar MRV Looks Like\u003C\u002Fh3>\n\n\u003Cp>A credible biochar carbon removal program requires documentation at every stage of the production and application process:\u003C\u002Fp>\n\n\u003Cul>\n  \u003Cli>\u003Cstrong>Feedstock sourcing records:\u003C\u002Fstrong> What biomass was used, from which farms, in what quantities.

This closes the loop between production and sequestration.\u003C\u002Fli>\n  \u003Cli>\u003Cstrong>Third-party verification:\u003C\u002Fstrong> Independent audit of the above documentation by an accredited verifier before credits are issued.\u003C\u002Fli>\n\u003C\u002Ful>\n\n\u003Cp>The good news is that biochar MRV is, in several respects, more tractable than soil carbon MRV. The carbon is locked at the point of production, you do not need to wait years and conduct repeated soil sampling to confirm sequestration. The H:Corg ratio can be measured in a laboratory within days of production. This makes biochar verification faster, cheaper, and more reliable than most soil-based carbon pathways.\u003C\u002Fp>\n\n\u003Ch3>Standards to Look For\u003C\u002Fh3>\n\n\u003Cp>When evaluating biochar carbon removal programs, buyers should look for alignment with at least one of the following standards: the \u003Cstrong>European Biochar Certificate (EBC)\u003C\u002Fstrong>, the \u003Cstrong>International Biochar Initiative (IBI) Biochar Standards\u003C\u002Fstrong>, or a recognised carbon credit methodology such as \u003Cstrong>Puro.earth's Biochar Methodology\u003C\u002Fstrong> or \u003Cstrong>Verra VM0044\u003C\u002Fstrong>. Programs that cannot point to one of these frameworks should be treated with caution, regardless of how compelling the narrative around soil health or farmer livelihoods may be.\u003C\u002Fp>\n\n\u003Ch2>Who Should Prioritise Biochar in Their Climate Strategy?\u003C\u002Fh2>\n\n\u003Cimg src=\"https:\u002F\u002Fimages.beetleregen.com\u002Fblogs\u002Fonnzzz0zi2rx08czq2uydvpzi-content-2-ba5d5268.webp\" alt=\"Illustration of a farmer, fashion brand professional, and corporate sustainability analyst connected by a circular supply chain loop with biochar at the center\">\n\n\u003Cp>Biochar carbon removal is not the right fit for every organisation or every climate strategy. But for specific stakeholder groups, it offers a combination of durability, co-benefits, and supply chain integration that is genuinely difficult to match.\u003C\u002Fp>\n\n\u003Ch3>Agricultural Businesses with Crop Residue Streams\u003C\u002Fh3>\n\n\u003Cp>Farms and agricultural cooperatives that generate significant quantities of crop residue, cotton stalks, rice husks, wheat straw, are natural candidates for biochar production. Converting residue that would otherwise be burned into biochar generates carbon credits, reduces air pollution, and improves soil health simultaneously. For smallholder farmers in India and Bangladesh, participation in a well-structured biochar program can represent a meaningful additional income stream alongside yield improvements from soil amendment benefits. The connection between regenerative practices and crop yield is well-established, and biochar is one of the tools that supports both outcomes.\u003C\u002Fp>\n\n\u003Ch3>Textile and Fashion Brands Seeking High-Durability Insetting\u003C\u002Fh3>\n\n\u003Cp>Brands that have made net zero commitments and need to demonstrate durable carbon removal within their supply chain, not just emission reductions, should be evaluating biochar seriously. The ability to source biochar credits from the same cotton supply chain that generates the feedstock creates a coherent, traceable narrative for ESG reporting. It also reduces the reputational risk associated with purchasing offsets from projects with no connection to the brand's actual operations.\u003C\u002Fp>\n\n\u003Cp>For brands already working on regenerative cotton sourcing in India or Bangladesh, biochar insetting is a natural extension of an existing program rather than a separate initiative. It adds a verified carbon removal dimension to soil health work that may already be underway.\u003C\u002Fp>\n\n\u003Ch3>Corporate Sustainability Teams Targeting Net Zero\u003C\u002Fh3>\n\n\u003Cp>For organisations with science-based net zero targets that include residual emission neutralisation, biochar credits offer something that most nature-based solutions cannot: verified, 100+ year durability that meets the permanence requirements of SBTi and similar frameworks. This makes biochar a strategic complement to emission reduction efforts, not a substitute for them. Teams navigating the complexity of carbon accounting for net zero claims will find the Modern ESG Dictionary a useful reference for understanding how durability, permanence, and additionality interact in credit markets.\u003C\u002Fp>\n\n\u003Ch3>Policy Makers and Climate Bodies\u003C\u002Fh3>\n\n\u003Cp>For government ministries and climate policy organisations evaluating nature-based solutions with measurable permanence, biochar offers a scalable pathway that can be deployed through existing agricultural infrastructure. India's agricultural residue burning problem, a significant source of seasonal air quality crises in states like Punjab and Haryana, represents both a challenge and an opportunity. Biochar programs that convert residue into stable carbon while improving soil health align with multiple policy objectives simultaneously: climate mitigation, air quality improvement, and agricultural productivity.\u003C\u002Fp>\n\n\u003Ch3>Who Should NOT Rely on Biochar as a Primary Strategy\u003C\u002Fh3>\n\n\u003Cp>Biochar is not a volume play at low cost. Organisations that need to neutralise very large emission volumes at the lowest possible cost per tonne will find soil carbon or reforestation credits more accessible in the near term. Biochar also requires a reliable feedstock supply chain and appropriate pyrolysis infrastructure, constraints that limit its deployment in regions without significant agricultural residue streams. And like any carbon removal tool, it should be used to address residual emissions after genuine reduction efforts, not as a substitute for decarbonisation.\u003C\u002Fp>\n\n\u003Ch2>Frequently Asked Questions About Biochar Carbon Removal\u003C\u002Fh2>\n\n\u003Ch3>Is biochar carbon removal permanent?\u003C\u002Fh3>\n\u003Cp>No carbon removal method is truly permanent in an absolute sense, but biochar is among the most durable nature-adjacent options available. Scientific studies show mean residence times of 100 to over 1,000 years, and major standards bodies classify biochar as meeting the 100-year permanence threshold required for net zero claims. The H:Corg ratio provides a measurable, verifiable indicator of stability at the point of production.\u003C\u002Fp>\n\n\u003Ch3>How is biochar different from activated carbon?\u003C\u002Fh3>\n\u003Cp>Both are carbon-rich materials produced from organic matter, but they serve different purposes. Activated carbon is processed at very high temperatures with steam or chemical activation to create an extremely porous structure used for filtration and adsorption. Biochar is produced at lower temperatures specifically for soil application and carbon sequestration. Activated carbon is not used as a carbon removal tool in the same way.\u003C\u002Fp>\n\n\u003Ch3>Can biochar credits be used for Scope 3 claims?\u003C\u002Fh3>\n\u003Cp>Yes, when the biochar is produced from feedstocks within the brand's supply chain and applied within the same supply chain, the resulting carbon removal can be attributed to Scope 3 emission reductions through carbon insetting. This requires robust MRV documentation and alignment with a recognised carbon accounting methodology. Credits purchased from third-party biochar projects can also be used for offsetting, though insetting is generally considered more credible for supply chain-specific claims.\u003C\u002Fp>\n\n\u003Ch3>What is the cost of biochar carbon removal per tonne of CO₂?\u003C\u002Fh3>\n\u003Cp>Costs vary significantly depending on feedstock availability, pyrolysis technology, scale of production, and the verification standard applied. Indicative ranges in the current market are USD 50, 200 per tonne of CO₂ removed. Supply chain-integrated programs that use agricultural residue as feedstock tend to be at the lower end of this range. Contact Beetle Regen for specific program pricing relevant to your supply chain context.\u003C\u002Fp>\n\n\u003Ch3>Does biochar work in all soil types?\u003C\u002Fh3>\n\u003Cp>Biochar performs best in degraded, low-organic-matter soils, conditions that are common in intensively farmed cotton and rice regions of India and Bangladesh. In already-fertile soils with high organic matter, the marginal benefit is lower. Soil testing before application is recommended to confirm compatibility and to establish a baseline for measuring carbon and soil health outcomes. For guidance on soil testing as a validation tool, see our post on soil testing as a brand validation tool for regenerative claims.\u003C\u002Fp>\n\n\u003Ch2>Taking the Next Step with Biochar Carbon Removal\u003C\u002Fh2>\n\n\u003Cp>The case for biochar carbon removal is not built on novelty. It is built on chemistry, verified by science, and increasingly supported by robust credit market infrastructure. For agricultural businesses sitting on crop residue streams, for textile brands that need durable insetting within their supply chain, and for corporate sustainability teams that need carbon removal they can defend to investors and regulators, biochar deserves a serious place in the conversation.\u003C\u002Fp>\n\n\u003Cp>The question is not whether biochar works. The question is whether your organisation has the supply chain context, the feedstock access, and the verification infrastructure to deploy it credibly. That is exactly the kind of assessment Beetle Regen is built to support.\u003C\u002Fp>\n\n\u003Cp>If you are evaluating biochar as part of a broader regenerative agriculture or net zero strategy, whether for a cotton supply chain in India, a textile brand's Scope 3 program, or a policy framework for agricultural residue management, \u003Ca href=\"https:\u002F\u002Fbeetleregen.com\u002F#contact\">reach out to the Beetle Regen team\u003C\u002Fa> to discuss what a verified, supply chain-integrated biochar program could look like for your specific context.
