Carbon Removal Project Data Has a Visibility Problem
If you're sourcing durable carbon removal credits, you may run into a familiar wall: project data scattered across dozens of developer websites, presented in inconsistent formats, with no easy way to compare one project against another. If you're a project developer, you face the mirror image of that problem: fielding individual requests for proposals, with no central place to showcase your available tonnes.
Get this wrong, and buyers may end up counting on carbon removal that never shows up - the delivery risk bugbear.
Between 2022 and 2024, high-durability engineered carbon removal made up just 2 percent of all carbon credit issuances. They remain in short supply, particularly the high-quality supply corporate buyers need. The gap is set to widen: our 2026 State of the Voluntary Carbon Market report found that more than 80% of the 2030 high-durability carbon removal projects are at risk of stalling and failing without additional offtake and financing commitments.
The Nasdaq Carbon Issuance Calendar, developed by Nasdaq in collaboration with Relae, offers an important first step toward addressing this information gap.
What Is the Nasdaq Carbon Issuance Calendar?
The Carbon Issuance Calendar is a centralized, accessible dashboard where carbon removal buyers and suppliers view standardized project data: future credit availability, indicative pricing, and project delivery status, all in one place.
The Nasdaq Carbon Issuance Calendar combines structured, developer-provided project data with project maturity assessment informed by Relae’s assessment framework and technical diligence. This helps users understand future CDR availability, indicative pricing, and potential project delivery risk through a single platform.
This expertise didn't appear overnight. It comes from sitting across the table with developers, stress-testing their science, mapping their delivery timelines against reality, and helping them show up to buyers as credible partners. The result is a track record that gives the framework embedded in the Carbon Issuance Calendar its depth. It's a starting point, built for buyers and suppliers to find each other on the basis of consistent, comparable information, using international class financial and information infrastructure.
How Buyers Should Use the Nasdaq Carbon Issuance Calendar
Today, if you're trying to procure durable carbon removal credits, you have no single place to start. You have to visit individual developer sites, request information through scattered channels, and compare projects that present data in entirely different formats before diligence has even begun. In many cases, you are comparing apples to oranges - different kinds of CDR projects with different durabilities, risks, and overall quality.
The Carbon Issuance Calendar provides a central starting point. You can view future credit availability, compare indicative pricing across projects, and begin assessing options without contacting each supplier one by one.
More importantly, the Carbon Issuance Calendar frames the data. Our scientists developed a delivery-oriented lens, built from reviewing over 900 carbon removal projects, drawing on the same rigor behind our Criteria for High-Quality Carbon Dioxide Removal, which we develop annually with Microsoft.
How Suppliers Reach Buyers Through the Carbon Issuance Calendar
If you're a project developer, the Nasdaq Carbon Issuance Calendar tackles visibility, one of the most persistent barriers to market access. You can list available tonnes, display indicative pricing, and reach a global audience of corporate and financial buyers at no cost.
The timing matters. Many first-of-a-kind engineered carbon removal projects are preparing to break ground and need bankable offtake agreements to secure financing before they can do so (a key aspect of CDR 2.0). Our analysis of approximately 140 high-durability carbon removal project developers found scale-up plans for 30 million tonnes of supply per year. Reaching that potential will take real demand: committed forward offtake, increased project equity investment, and access to lending.

What to Read Next
Independent Project Assurance Is Likely Your Best-Returning Spend
Key Takeaways
- The decision to fund a project is determined by a holistic review of project development maturity. This applies across capital-intensive projects, including low-carbon power generation, carbon capture and storage (CCS) solutions, sustainable aviation fuel (SAF), and broader transition infrastructure build-out. Both technical and commercial workstreams must be developed in parallel to avoid project failure.
- Early scope decisions, such as site selection, core technology selection, and nameplate capacity, are cheap to make but become exponentially disruptive and costly to reverse.
- Independent challenge and verification is tangible evidence of a disciplined, well-managed capital development process.
Bridging the Gap from Announcement to Delivery
Among project developers, a perception often persists: seeking external review signals a project in distress. In capital budgeting discussions, subjecting engineering scope and commercial assumptions to third-party interrogation can be misconstrued as a vote of no confidence in the primary delivery team.
In reality, the reverse is true. Across complex infrastructure, independent challenge is the disciplined stage-gate practice that protects capital by reconciling technical reality with commercial terms before designs are locked.
Independent Challenge Is a Sign of Strength, Not Doubt
Across capital projects, and in particular within emerging low-carbon industrial infrastructure, the gap between announced projects and delivered assets remains stark. Data from the Mission Possible Partnership’s Global Project Tracker reveals that fewer than 17% of announced commercial-scale clean industrial facilities worldwide have reached Final Investment Decision (FID) or commercial operations, leaving more than 800 major decarbonization projects stalled in front-end development.
The causes of developmental paralysis are multifaceted. While macroeconomic interest rate shifts and global supply chain disruptions sit largely outside a developer's control, project definition and developmental discipline remain entirely manageable. Even amid external volatility, a project designed with resilience will have a far greater likelihood of success.
Independent review and assurance directly strengthen a project’s chance of success and overall value. Large global project delivery organizations have applied this discipline for decades by deploying independent teams to evaluate project readiness at every stage gate. For teams lacking a dedicated internal oversight organization, or those deploying first-of-a-kind facilities, third-party independent review provides the necessary rigor to facilitate project success.
Relae’s (formerly Carbon Direct) work with Stockholm Exergi is a clear example: independent assurance helped build funder and regulator confidence in a first-of-a-kind carbon removal facility with no direct precedent to benchmark against.
Why Projects Stall Between Announcement and FID
Low-carbon infrastructure and net-zero industrial projects carry unique risks compared to the repeat delivery of established designs. Exciting new developments run a higher risk of falling victim to optimism bias or compressing development timelines to meet public announcement milestones.
It is a natural human tendency for project champions to focus on the upside during early development. However, early momentum must be balanced with processes that reintroduce industrial lessons, supply-chain realities, and operational resilience.
Front-End Loading (FEL) is a well-evidenced approach for improving capital project outcomes. Decades of benchmarking by Independent Project Analysis (IPA) show that approximately two-thirds of industrial megaprojects suffer capital cost overruns or schedule slippage of 25% or more, or encounter severe operational problems lasting more than two years post-startup. This pattern is repeating in low-carbon infrastructure: IPA’s analysis of 12 completed low-carbon projects found average cost escalation of 31% and schedule slip of almost 50%. Rigorous front-end definition remains the single strongest predictor of whether a project will achieve its cost and schedule targets.
As highlighted in the CDR 2.0: Five Pillars of Successful Project Deployment and Delivery report published by Relae, projects falter when developers push ahead without stress-testing the full delivery framework. Stage gate reviews are the mechanisms that evaluate the total project concept and underlying business case. They are most effective when executed as independent cold-eye evaluations prior to each funding gate, identifying and mitigating vulnerabilities long before final investment decisions are reached.
What Funders Need to See at Each Gate
Different stages of project development rely on distinct capital sources, each requiring specific proof points before deploying funds.
Before FEED Funding: Justifying the Engineering Spend
Front-End Engineering Design (FEED) is a major financial commitment, typically costing between 2% and 4% of total project capital cost. The funders backing this stage are usually the developer’s own balance sheet equity, strategic partners, or public grant programs. Before allocating millions of dollars to detailed engineering, these funders need confidence on the fundamentals:
- A technically sound process concept, confirmed utility balances, and an energy integration scheme that fits the site.
- Secured site control, clear zoning pathways, and no environmental fatal flaws that could derail permitting.
- Documented availability of required feedstocks, water and power, paired with demonstrable interest from target off-takers.
Before FID: Proving Bankability and Commercial Closure
As a project approaches FID, the funding audience shifts to conservative commercial lenders, infrastructure funds, and binding offtake counterparties. These capital providers are not underwriting strategic vision; they are underwriting long-term operational cash flows and debt service. Depending on the project and financing structure, capital providers may require:
- A high-confidence capital cost estimate (AACE Class 2 or Class 3) backed by frozen Piping and Instrumentation Diagrams (P&IDs), firm equipment quotes, and a realistic execution schedule with clear critical paths.
- Bankable engineering, procurement, and construction (EPC) structures that clearly allocate risk, include performance guarantees and enforceable liquidated damages.
- Fully executed, binding offtake and feedstock agreements, along with non-appealable permits and completed utility interconnection agreements, with remaining conditions clearly understood.
- An objective, third-party challenge review that assesses operational viability and distinguishes an executable engineering plan from an aspirational concept.
Commercial and Technical Co-Development: The Stage-Gate Method in Practice
A project rarely fails because of an isolated mechanical issue or a purely commercial misstep; failure happens when technical decisions and commercial terms are negotiated in silos and decisions are made without understanding of the wider implications.
We see this disconnect play out in several ways, including:
- Sizing capacity before testing market demand: An engineering team may size a facility to maximize thermodynamic efficiency and economies of scale, only for the commercial team to discover buyers will only commit to half that volume. The developer is left with an oversized, unbankable design requiring fundamental rework.
- Setting product specifications before negotiating offtake: Process engineers frequently design systems around standard vendor packages. However, when downstream transport, processing, or storage networks enforce strict purity standards, the facility faces costly equipment redesigns. This issue has materialized directly within European CCS networks. Open-access offshore storage operators, such as Norway's Northern Lights project, established strict cross-border CO2 specifications requiring tighter moisture and impurity thresholds than originally designed for.
- Locking Electrical Loads Prior to Interconnection Verification: As detailed in Relae’s analysis of physical infrastructure bottlenecks, scale is rarely constrained by capital availability; it is dictated by electrical transmission queues, substation headroom, and 24/7 firm power availability. Freezing electrical demand before verifying utility interconnection timelines risks stranding engineering work on an asset that cannot connect to the grid.
How Relae Stress Tests Projects at Each Gate
Independent reviews at each stage-gate improve success rates by stress-testing assumptions before presenting to lenders, infrastructure investors, or corporate buyers. Relae reviews projects across five categories using the TECOP framework:
- Technical: Verifying technology readiness levels (TRL), mass and energy balances, plot plan constructability, and operational availability under real-world conditions.
- Economic: Capex benchmarking, operating contingency adequacy, utility tariff sensitivities, and financial model cash-flow resilience.
- Commercial: Offtake agreement structures, feedstock contracts, contracting boundaries, EPC contract structures, and counterparty creditworthiness.
- Organizational: Owner's team capabilities, internal stage-gate governance, contractor oversight mechanisms, and execution capabilities.
- Political: Statutory permitting status, regulatory durability, carbon market policy exposure, and local community social license.
The TECOP framework is relevant for evaluating delivery risk across all project types, see more in Relae’s Criteria for High-Quality Carbon Dioxide Removal, Delivery Risk Appendix.
What makes this approach effective is sitting on both sides of the table. Having completed over 250 deep-dive technology reviews, 900+ project evaluations, and advised on more than $6 billion in industrial project finance, Relae has extensive experience evaluating the considerations important to institutional funders and buyers.
The Value of Early Independent Project AssuranceIncorporating independent review should be standard practice for modern infrastructure delivery. Because funders will perform their own rigorous diligence regardless, conducting an independent evaluation early enables developers to address vulnerabilities proactively and present a more resilient business case.
Commissioning an independent team for a cold-eye review during early project formation can be a cost-effective way to identify potential risks before they become expensive to address. Catching an unworkable process assumption, an oversized capacity plan, or a misaligned commercial interface during pre-FEED costs a tiny fraction of what it takes to fix those issues during construction
Ultimately, independent challenge is not an admission of doubt, but the disciplined stage-gate practice that protects capital by reconciling technical reality with commercial terms before designs are locked, signaling to partners, and your future funders that your project is built to deliver.

Frequently Asked Questions
What is independent project assurance?
Independent project assurance is a structured review of a capital project by a team that sits outside the project’s delivery organization. Reviewers test the engineering scope, cost estimate, schedule, commercial agreements and permitting position against what funders will require at the next stage gate. The developer receives a clear list of gaps, risks and proposed mitigations prior to presenting the project to lenders, investors or buyers.
When should a developer commission an independent project review?
Periodically throughout the project development process - at a minimum before each major funding gate, but smaller reviews are also beneficial at earlier stages when key concept and technology decisions are being made. A review before Front-End Engineering Design (FEED) tests whether the process concept, site and supply of feedstock, water and power justify the engineering spend. A review before Final Investment Decision (FID) tests whether the cost estimate, EPC structure and binding agreements will satisfy lenders. Site, technology and capacity decisions are cheap to change in pre-FEED and expensive to reverse once detailed engineering starts.
What does an independent project review assess?
Relae structures its reviews around the TECOP framework, which covers five risk areas: technical (technology readiness, mass and energy balances, constructability), economic (capex benchmarking, contingency, financial model resilience), commercial (offtake, feedstock and EPC contracts), organizational (owner’s team capability and stage-gate governance) and political (permitting, regulatory durability and social license). Reviewers also check that technical and commercial decisions are aligned, because projects often fail where the two are developed in silos.
How does an independent project review differ from lender due diligence?
An independent project review applies a holistic approach identifying not only gaps, but also opportunities to add value and strengthen the business case. Lender and investor due diligence is often purely looking at risks and gaps, prior to committing capital. Lender diligence protects the funder and reports its findings at a point when changes are costly and can delay financial close. A developer-commissioned review takes place earlier, so the project team can fix weaknesses in scope, cost or contracts before funders see them.

Marine Carbon Dioxide Removal: What It Is and How It Works
Key Takeaways
- Marine carbon dioxide removal (mCDR) uses ocean-based processes—primarily ocean alkalinity enhancement (OAE) and direct ocean removal (DOR)—to capture and durably store atmospheric carbon dioxide (CO₂), without the land and freshwater constraints of terrestrial methods.
- The ocean already absorbs roughly 29% of human-caused CO₂ emissions each year, according to the 2025 Global Carbon Budget, and mCDR technologies aim to safely enhance that natural uptake without worsening ocean acidification.
- For corporate carbon buyers and project developers evaluating mCDR, the Criteria for High-Quality Marine Carbon Dioxide Removal, developed by Microsoft and Relae, outlines standards to guide responsible mCDR deployment at scale.
Reducing carbon dioxide (CO₂) emissions alone is no longer sufficient to limit global warming to 1.5°C. To effectively address climate change, scientific consensus highlights the need to remove carbon dioxide already present in the atmosphere. Marine carbon dioxide removal (mCDR), a form of ocean-based carbon removal, offers a scalable solution by leveraging the ocean’s natural ability to absorb and store carbon, without the land and resource limitations associated with terrestrial carbon removal methods.
This guide explores the fundamentals of marine carbon dioxide removal, including how it works, the technologies involved, and its role in global decarbonization.
What Is Marine Carbon Dioxide Removal?
Marine carbon dioxide removal uses ocean-based processes to capture and store carbon dioxide from the atmosphere. mCDR techniques fall into two primary categories:
- Biotic CDR, which includes using photosynthetic fixation, microalgae cultivation, and terrestrial biomass sinking, to capture and store carbon.
- Abiotic CDR, which influences CO₂ concentrations and carbonate chemistry in the seawater to absorb atmospheric CO₂ without increasing acidity. There are two main abiotic mCDR pathways: ocean alkalinity enhancement (OAE) and direct ocean removal (DOR).
How Does Marine Carbon Dioxide Removal Work?
Marine carbon dioxide removal functions via the air-sea gas exchange—a process by which the atmosphere and surface seawater maintain equal CO₂ concentrations—meaning a shift in one leads to a corresponding change in the other. This exchange allows the ocean to absorb or release CO₂ back into the atmosphere depending on concentration levels and factors like pH.
Once absorbed by the ocean, CO₂ exists in several forms, including dissolved CO₂, carbonates, and bicarbonates, influencing the ocean's pH levels. As atmospheric CO₂ levels rise, the oceans absorb roughly 12 GtCO2 annually, approximately 29% of anthropogenic CO2 emissions. This increase is disrupting the natural CO₂ balance and contributing to ocean acidification.
mCDR methods like ocean alkalinity enhancement and direct ocean removal use safe and controlled processes to increase the amount of CO2 absorbed from the atmosphere while mitigating acidification.
Understanding Ocean Alkalinity Enhancement (OAE)

Ocean alkalinity enhancement (OAE) captures and stores atmospheric CO₂ as dissolved carbonates in the ocean by increasing the alkalinity of seawater using one of two primary methods:
- Adding alkaline minerals such as olivine or basalt to seawater.
- Using electrochemical methods to add alkaline compounds to seawater.
Both of these methods increase the alkalinity of seawater and, thereby, its capacity to absorb atmospheric CO₂ without acidification.
OAE methods can also differ by location and the manner in which seawater interacts with alkaline substances and atmospheric CO₂. This interaction may occur in the open ocean or within a controlled mCDR project facility. Each approach involves trade-offs: open ocean methods tend to be less energy-intensive but present greater uncertainties and challenges in measurement, reporting, and verification (MRV).
Understanding Direct Ocean Removal (DOR)

Direct ocean removal (DOR), also called direct ocean capture (DOC), removes CO₂ dissolved in seawater using the controlled acidification of seawater in a closed system using one of two primary methods:
- Electrochemical methods such as electrolysis of seawater or electrodialysis
- The addition of minerals like olivine and basalt.
The acidified and CO₂ depleted seawater is neutralized to native pH and allowed to equalize with and remove atmospheric CO₂. Once removed, CO₂ can be safely stored using geologic storage with a durability of >1,000 years.
Nomenclature for Direct Ocean Removal
Direct ocean removal is more commonly referred to as direct ocean capture. Relae believes the term direct ocean removal (DOR) is more accurate for two reasons:
- We think it is scientifically more accurate as both OAE and DOR remove CO₂ from the atmosphere but DOR directly removes CO₂ from the oceans, where in OAE, CO₂ is captured as bicarbonates in the ocean.
- DOC is a term for dissolved organic carbon, which is frequently used in mCDR project documents, reports, and the scientific literature.
Key Benefits of Marine Carbon Dioxide Removal
Understanding how mCDR works highlights its potential to address climate challenges. Here are the key benefits that make it a critical tool in global decarbonization strategies.
- Scalable carbon removal without land constraints: Marine carbon dioxide removal does not require large land areas or significant freshwater resources, making it highly scalable.
- Harnessing the ocean’s natural carbon sink: The ocean absorbs about 25% of human-generated CO₂ annually. mCDR enhances this natural process, increasing carbon storage without accelerating ocean acidification.
- Diverse technological pathways for flexibility: Technologies like ocean alkalinity enhancement and direct ocean removal offer flexible solutions tailored to different environments and project needs.
- Global reach with a large surface area: Covering over two-thirds of the Earth’s surface, the ocean provides an expansive platform for mCDR technologies globally.
- Potential to mitigate ocean acidification: Some mCDR methods, such as ocean alkalinity enhancement, not only remove CO₂ but also help restore ocean pH levels, supporting marine ecosystem health.
Challenges of Marine Carbon Dioxide Removal
While mCDR holds significant promise, it also presents challenges that must be addressed for responsible deployment.
- Technical scalability and efficiency: Scaling mCDR technologies to achieve meaningful carbon removal while maintaining energy efficiency remains a significant hurdle.
- Potential environmental impacts: Altering ocean chemistry may pose risks to marine ecosystems, with long-term effects still not fully understood.
- Measurement, reporting, and verification (MRV) complexity: Accurately measuring CO₂ removal and ensuring its durability requires advanced monitoring systems, which are still evolving.
- Regulatory and governance gaps: Clear global policies are needed to oversee mCDR deployment, manage environmental risks, and ensure accountability.
- Public perception and ethical considerations: Concerns around geoengineering and potential unintended consequences may impact public acceptance and policy support.
Deploying Marine Carbon Dioxide Removal
As mCDR technologies evolve, effective deployment will rely on adaptive management practices to address technical, environmental, and regulatory challenges. This includes robust MRV systems for accurate CO₂ removal tracking and continuous ecosystem monitoring to mitigate potential risks to marine life.
Collaborative efforts between scientists, policymakers, and project developers are key to establishing clear regulatory frameworks, optimizing technologies for efficiency and scalability, and building public trust. These practices ensure mCDR can be scaled responsibly while safeguarding ocean health.
The Future of Marine Carbon Dioxide Removal
As technologies like ocean alkalinity enhancement and direct ocean removal advance, their potential to deliver large-scale, durable carbon removal is becoming increasingly evident. Realizing this potential requires more than technological innovation—it depends on rigorous environmental monitoring, transparent reporting, and strong collaboration among project developers, carbon buyers, and policymakers.
Establishing clear, consistent standards for high-quality mCDR is essential to ensure both climate effectiveness and environmental safety. To support this, Microsoft and Relae have partnered to develop the Criteria for High-Quality Carbon Dioxide Removal.
Frequently Asked Questions
What is marine carbon dioxide removal (mCDR)?
mCDR uses ocean-based processes, primarily ocean alkalinity enhancement and direct ocean removal, to capture and durably store atmospheric CO₂. It works by increasing the ocean's natural capacity to absorb CO₂ without increasing acidification.
How does marine carbon dioxide removal compare to land-based methods like direct air capture or reforestation?
Unlike land-based approaches, mCDR doesn't require large land areas or freshwater, and the ocean's size gives it significant scaling potential. It's earlier-stage than more established pathways, though, with measurement and environmental monitoring standards still maturing.
Is marine carbon dioxide removal proven and scalable today, or still emerging?
mCDR technologies have shown promising results in lab testing and early deployments, but confirming safety and effectiveness at a large real-world scale requires more monitoring data. It's best described as an emerging pathway with strong near-term momentum, not yet a mature, at-scale solution.
What should a company look for when evaluating a marine carbon dioxide removal project or credits?
Buyers should look for rigorous carbon MRV paired with equally rigorous monitoring of ocean ecosystem health (eMRV), transparent reporting, and adherence to established frameworks like the Criteria for High-Quality Carbon Dioxide Removal.
SBTi Emphasizes Near-Term Carbon Removal in Revised Corporate Standard Draft
Key Takeaways
- Near-term role for carbon removals: The revised Science-Based Targets Initiative (SBTi) Corporate Net Zero Standard (CNZS) v2.0 proposes requiring or recognizing interim carbon dioxide removal (CDR) targets before companies reach net zero. This shift aims to scale up the CDR industry in line with climate science and ensure companies address residual emissions earlier rather than deferring action until their net-zero target year.
- Revised target frameworks and increased accountability: The draft standard introduces key changes, including separate targets for scope 1 and 2 emissions, enhanced scope 3 target-setting guidelines, and the recognition of market-based mechanisms for indirect mitigation of scope 3 emissions. It also requires companies to publicly disclose transition plans and assess implementation progress against targets.
- Potential for stronger action on removals: While the proposed updates are a step forward, the final standard should make near-term CDR targets mandatory rather than optional and should expand to include those for projected scope 3 residual emissions, not just scope 1. Without these stronger mandates, demand for early-stage CDR investments may remain limited, potentially slowing progress toward net-zero goals.
- Companies should prepare now: Businesses should start integrating CDR into their climate strategies now so they are equipped to navigate procurement of high-quality removal credits in the voluntary carbon market. Preparing ahead of the final CNZS v2.0 release will help companies align with science-based decarbonization pathways and demonstrate climate leadership.
What the Latest SBTi Update Means for Corporate Climate Action
On 18 March, 2025, the Science Based Targets Initiative (SBTi) released its draft Corporate Net Zero Standard (CNZS) v2.0, significantly updating its framework for corporate net-zero target setting for the first time since 2021. The draft proposes new approaches for companies to support carbon dioxide removal (CDR) in the transition to net-zero emissions, a move that could help scale the nascent CDR industry.
This release is part of a broader revision, with key proposed updates including:
- Requiring public disclosure of transition plans after companies set targets.
- Separating targets for scope 1 and 2 emissions.
- Enhancing the scope 3 target-setting framework using an impact-based prioritization process.
- Recognizing indirect mitigation (e.g., book-and-claim commodity certificates) for hard-to-trace scope 3 emissions.
- Defining a role for emissions removals in the transition to net zero.
- Providing options to recognize company leadership in beyond value chain mitigation (BVCM).
- Assessing corporate progress against targets to bolster accountability.
While formal recognition of removals in the transition to net zero is a positive step, stronger incentives will be needed in the final CNZS to ensure companies take meaningful early action on CDR. The draft standard is open for the first of two public consultations until 1 June, 2025, with a finalized version expected to launch in 2026.
What Remains the Same From the Current Standard?
SBTi’s framework remains focused on three core requirements for companies:
- Reducing emissions year-on-year to reach an approved science-based target (SBT) by 2050 or earlier.
- Investing in beyond value chain mitigation (BVCM) in the transition to net zero to support near-term global decarbonization efforts.
- Neutralizing remaining emissions from the net-zero year (achieved after at least 90% emissions reductions) and onwards with high-quality, permanent carbon removal.
Carbon credits representing emissions reductions and removals remain ineligible for meeting reduction targets within a company’s value chain (SBTs).
What’s New in CNZS v2.0 for Carbon Removals?
Until now, the SBTi encouraged companies to invest in CDR through mechanisms such as BVCM, but has not proposed requiring removal before their target net-zero year. As a result, organizations had little clarity or incentive to invest in CDR ahead of their net-zero target date, dampening near-term demand for carbon removal and delaying the industry's growth.
The new draft changes this by proposing three options for the V2.0 Standard that address the impact of residual emissions during the transition to net zero:
- Option 1 (requirement): Companies are required to set near- and long-term removal targets, including interim CDR milestones,¹ to address projected residual emissions.
- Option 2 (optional with recognition): Companies can set and receive recognition for removal targets to address projected residual emissions.
- Option 3 (flexibility of mechanism): Companies have the flexibility to address expected residual emissions either entirely through additional emissions reductions within their value chain, entirely through removals, or via a combination of both.
Notably, all three approaches apply only to residual scope 1 emissions.
On top of these approaches, SBTi has suggested two options for the minimum durability threshold of CDR purchases in their draft standard. Removals will either need to follow a ‘like for like’ approach,² where CDR storage must match the atmospheric lifetime of residual emissions, or a gradual transition approach, where carbon storage durability increases over time.
Why Mandating CDR Matters
Mandating near-term CDR reinforces the need for immediate climate action, ensuring that carbon removals complement emissions reductions rather than being deferred until the net-zero target year. The urgency of early CDR investment is clear:
- Limiting global warming to well below 2°C above pre-industrial levels requires removing billions of tonnes (gigatonnes) of carbon dioxide annually by mid-century.
- The CDR industry is in its early stages and requires sustained investment today to scale in time.
- If companies wait until their net-zero year to purchase CDR, the supply of high-quality removal credits is unlikely to be sufficient.
As part of the proposed removal targets in Option 1 (above), the CNZS v2.0 would require companies to gradually increase CDR purchases over time, ramping up to 100% of a company’s projected residual scope 1 emissions in the net-zero target year (<10% of baseline year emissions).³
What More Can Be Done?
The potential introduction of required removal targets would be a significant and welcomed step, reinforcing the importance of near-term CDR investment to support industry maturation and climate goals. However, mandatory near-term CDR targets represent only one of three potential pathways for the V2.0 standard. Moreover, neutralization of residual emissions on the path to net zero is only proposed for scope 1 emissions. While the SBTi provides clear rationale for this,⁴ SBTi should not let the complexity of projecting scope 3 emissions be a barrier to climate change mitigation. Scope 3 emissions represent the majority of emissions from SBTi-aligned companies. Furthermore, companies with high scope 3 emissions typically have a higher ability to pay compared to their industrial counterparts with high scope 1 emissions.
If interim removal targets are made optional, and scope 3 emissions remain excluded, the demand signal for near-term CDR will be limited. The public consultation (and advice of Expert Working Groups that SBTi is convening) will be essential in determining which proposed guidance matures into the final standard; consultation feedback can be provided here prior to June 1, 2025.
How Businesses Can Prepare for CNZS v2.0
Companies aligning with SBTi’s evolving guidance should begin to integrate CDR into their climate strategy now. This means:
- Understanding their residual emissions forecast and planning early investments.
- Developing a company-specific climate strategy to incorporate CDR into their sustainability roadmaps in tandem with plans to reduce value-chain emissions.
- Engaging early in the voluntary carbon market to implement these strategies and develop procurement processes to support high-quality removal projects.
- Ensuring credibility by selecting removal projects aligned with scientific best practices.
Conclusion: A Step in the Right Direction, But More Certainty Is Needed
The CNZS v2.0 draft represents a critical turning point for corporate climate action with options to formalize the role of early CDR investment through interim removal targets for signatories. However, SBTi must take a stronger stance in the final version of the revised standard by choosing to adopt requirements for near-term neutralization (rather than leaving this optional), including projected residual scope 3 emissions in near-term CDR targets, aligning durability requirements with climate science, and defining removal quality standards to ensure these efforts drive meaningful climate impact. Organizations seeking to align with this guidance should prepare by developing a comprehensive climate strategy that accounts for science-based decarbonization pathways and recognizes the role of early-stage investment in CDR solutions.
Introducing the Diligence Collection: High-Quality Carbon Removal, Vetted
Key Takeaways
- Relae (formerly Carbon Direct) has conducted over 900 comprehensive, rigorous reviews of carbon removal (CDR) projects around the world. But fewer than 10% meet our standard for high-quality. In today’s market, scientifically-credible CDR supply is scarce.
- To identify high-quality projects, buyers and investors previously had to commission numerous deep diligences, which often made it a lengthy and complex process, not well-suited to most market participants.
- The Diligence Collection changes that paradigm by giving you direct access to existing comprehensive analysis on a curated set of high-quality CDR projects. The hard work of identifying high-quality projects is already done, allowing you to move faster, spend less, and procure with more confidence.
Relae Sets the Bar for High-Quality CDR
Since 2020, every year Relae has released an updated version of the Criteria for High-Quality Carbon Dioxide Removal in collaboration with Microsoft. The Criteria set the standard for scientific rigor across nine CDR pathways and across six technical dimensions. Using this standard, the Relae team has conducted diligence on over 900 CDR projects across 63 countries. Our diligence has been used for over 50% of all tonnes contracted through announced CDR offtake agreements worldwide, including diligence for the majority of tonnes from Microsoft’s announced offtakes. This gives Relae a uniquely deep understanding of the CDR market; and importantly, it has highlighted that high-quality projects in the voluntary carbon market are scarce.
Quality Is the Central Challenge in CDR Procurement
Only 10% of the projects that Relae has assessed meet our high-quality criteria. This means that without rigorous, scientific assessment, buyers and investors run real risk of exposing themselves to delivery shortfalls, financial loss, and reputational damage.
This presents a series of challenges to buyers and investors interested in procuring or investing in CDR. Conducting diligence on CDR projects is time-intensive, complex, and requires deep expertise. Building the internal capacity to rigorously evaluate a wide variety of CDR projects isn’t practical for most actors. But conducting the in-depth diligence required to procure or invest confidently requires real commitment, especially when a significant proportion of the projects diligenced may not be high-quality. Finding the needle in the CDR haystack isn’t easy.
The Case for Curated CDR
The Diligence Collection directly addresses these challenges by providing self-serve access to diligence on a curated set of high-quality CDR projects vetted by Relae. Every project has already been evaluated against the Criteria for High-Quality Carbon Dioxide Removal, the science-based benchmark jointly established by Relae in collaboration with Microsoft. The Collection includes projects reviewed on behalf of Microsoft and other major buyers, and more broadly reflects our diligence work across the market.
With the Diligence Collection, you're not starting from scratch. Instead, you're starting from a shortlist of some of the highest-quality CDR opportunities available, with robust scientific diligence to back them up. The bottleneck that's slowed procurement for so many organizations is no longer a concern.
The Collection offers two levels of diligence, matched to the level of scrutiny your commitment warrants:
- Desk review: An executive-level assessment using available project documentation, enough to make an informed shortlisting decision or purchase.
- Deep diligence: A comprehensive technical evaluation covering project design, operational risk, technology assessment, policy landscape, and community impacts, reflecting the same methodology that's informed the procurement programs of Microsoft and other major buyers.
Both tiers include the option to commission an updated evaluation as your needs evolve.
What Rigorous CDR Diligence Involves
The depth of Relae’s diligence sets the Diligence Collection apart. Our desk review process involves conducting detailed assessments to evaluate projects against 6 quality principles: social harms, benefits, and environmental justice; environmental harms and benefits; additionality and baselines; measurement, monitoring, reporting, and verification; durability; and leakage. The result is a comprehensive report that assesses projects against these criteria, highlighting the project's overall quality, strengths, and weaknesses in a clear, succinct way that supports decision-making.
Many of our reports dig even deeper. Our deep diligences assess both a project’s quality and its delivery risk. To evaluate delivery risk, we assess projects across 5 elements: technologic, economic, commercial, operational, and political. Deep diligence is conducted over 3-4 months, which includes weekly back-and-forth with the supplier and a site visit to understand all of the nuances of the project and validate developer claims on the ground. The resulting report not only documents a project's strengths and weaknesses, but also outlines risk mitigation measures and recommends improvements over time.
Broader Access, Stronger Market
Forward offtake demand in the CDR market has historically concentrated among a handful of large buyers, and as our 2026 State of the Voluntary Carbon Market report notes, diversifying that pool is essential to enabling the next generation of CDR supply. The Diligence Collection is built to support exactly that. By making the scientific rigor behind the world's largest CDR transactions available through a self-service platform, it opens credible procurement to organizations at any stage of purchasing. More buyers accessing high-quality, de-risked projects means more capital flowing to suppliers, more projects able to scale, and a more resilient market that doesn't depend on a small number of actors to function.
High-quality CDR supply is scarce, and the best projects are in high demand. The Diligence Collection gives you the foundation to act efficiently and with confidence, without starting from zero.

Frequently Asked Questions
Who Can Access the Relae Diligence Collection?
The Diligence Collection is available to approved subscribers, including CDR buyers and investors seeking to more efficiently evaluate carbon removal projects. To preserve the independence and integrity of the Collection and protect proprietary diligence insights, access is not available to project developers or rating agencies.
How Is the Relae Diligence Collection Different From a Rating Agency or Market Intelligence Platform?
Most rating platforms optimize for quantity; we optimize for quality. Our process includes pathway-specific risk assessments and, in many cases, site visits from our in-house scientists, engineers, and technical experts—the same multidisciplinary team and judgment behind our own portfolio decisions and the procurement programs we support directly. The Collection also includes projects diligenced before they've received external ratings, giving you visibility into promising opportunities at the pre-commercialization stage.
Does Inclusion in the Relae Diligence Collection Mean Relae Endorses a Project?
Inclusion means a project was evaluated through our scientific diligence process and, at the time of review, met our Criteria for High-Quality Carbon Dioxide Removal. It reflects a positive diligence outcome based on the information available during the review and the project's stage of development at that time. As projects and market conditions evolve, we recommend considering whether updated diligence or additional evaluation is appropriate for your specific procurement or investment objectives.
Can I Request Diligence on a Project That Isn't Already in the Collection?
Yes. You can commission us to diligence a specific project based on your procurement or investment priorities. Whether it's later added to the Diligence Collection depends on a few factors beyond just meeting our quality bar, including consent from you as the commissioning buyer and approval from the project developer.
US Wood Pellet Producers: The UK Market Is Contracting. Four Markets Are Beginning.
Key Takeaways
- The UK's new biomass Contracts for Difference framework will cut industrial wood pellet imports by slightly more than half starting in April 2027. As a result, US producers will be left competing for only 1.6 million GST, an 80% reduction in US-addressable volume, with no successor market locked in.
- US wood pellet producers who move now to upgrade sustainability credentials and build relationships in emerging markets will be best positioned to capture the next generation of demand; those who wait may find the most attractive offtake opportunities already structured around someone else's supply.
- Four domestic markets now present producers with new demand opportunities: cofiring, sustainable aviation fuel (SAF), low-carbon steel, and bioenergy with carbon capture and storage (BECCS). Of these, BECCS for data centers is the strongest structural fit: hyperscalers need clean firm power, pellet mills need offtakers, and the feedstock infrastructure is already in place.
The Demand Cliff Is Real, and the Timeline Is Short
A pellet made in southern Mississippi this morning will be burned in a UK boiler about four weeks later. North America is on pace to ship more than 9 million green short tons (GST) of pellets to the UK each year—making the UK the world's largest consumer of wood pellets since 2018. The US Southeast is at the center of that supply chain: 28 large mills, 13.5 million GST of production capacity, rail spurs, export terminals, and bulk carriers, built almost entirely around UK demand.
However, the UK's new low-carbon Contracts for Difference (CfD) framework caps biomass power generators at a 27% annual capacity factor starting April 2027, down from roughly 64% today. When run hours fall by half, pellet demand follows. Existing subsidies expire in the first quarter of 2027, and the new CfD runs only to March 2031 with no commitment beyond that. Plant closures in Arkansas and Washington state, along with reduced output in Canada, are already early signals of supply chain contraction.
The Math of Who Gets Squeezed
The math is stark. By the second quarter of 2027, total annual UK pellet demand drops to 4.9 million GST. Of that:
- Approximately 2.3 million GST goes to captive, integrated UK supply chains.
- Approximately 1.0 million GST goes to Baltic suppliers, whose shipping times of one week or less become a decisive advantage as UK plants shift from baseload to dispatchable operation.
That leaves US producers competing for only 1.6 million GST. If Baltic suppliers capture more, US wood pellet exports to the UK could be effectively eliminated by 2031.

Sustainability qualification is also tightening. The new CfD cuts the supply-chain emissions ceiling from 55.6 grams of carbon dioxide equivalent per megajoule (gCO₂e/MJ) to 36.6 gCO₂e/MJ. The framework assesses compliance mill by mill, not on a portfolio average. A cleaner mill cannot carry a dirtier sibling through the door.
The producers who understand this math now have roughly 18 months to position themselves for what comes next.
From Stranded Supply to New Markets
The US Southeast's wood basket is robust: abundant inventory, strong growth-to-removal ratios, and more available residues than ever. The infrastructure is in place. The question is whether the next generation of markets can be developed quickly enough to redeploy this supply before the infrastructure sits idle.
Four pathways stand out as the strongest options for redeploying US pellet supply: BECCS for data centers, low-carbon steel, SAF, and domestic cofiring. We have rigorously assessed the logistics economics, sustainability cases, and project development for each.
BECCS for Data Centers: The Strongest Structural Fit
BECCS as a power source for data centers is the most compelling match for the situation pellet producers now face. The timing, feedstock requirements, and buyer characteristics align closely in a way that few other emerging markets can match.
Hyperscalers, the large data center operators driving an unprecedented surge in electricity demand, are signing deals for nuclear, geothermal, and small modular reactors alongside natural gas and renewables. They are doing this because annual Renewable Energy Certificates (RECs) are no longer sufficient to compensate for their scope 2 emissions, and they need clean, firm generation that can be matched to load on an hourly basis.
BECCS delivers exactly that. The Louisiana Green Fuels project—advanced by Strategic Biofuels and Relae (formerly Carbon Direct)—illustrates the model: regionally sourced forestry residues and sawmill waste generate 75 megawatts (MW) of firm electricity while sequestering over one million tonnes of CO₂ annually in deep saline formations. An ample supply of wood pellets creates a strategic opportunity for similar projects to move forward with certainty around feedstock processing, logistics, and costs.
The remaining commercial barrier is deal structure, not technology. No data center operator has yet signed an agreement to purchase both the electricity and carbon removal credits from a single BECCS plant. As scope 2 accounting tightens and domestic pellet supply becomes more readily available post-2027, the conditions for structuring the first such deal are improving fast.
"Pellet mills and data center developers have complementary problems: mills need offtakers, and data centers need local, dispatchable, clean power they can match to load on an hour-by-hour basis. BECCS is one of the few technologies that could solve both at once, and hyperscalers have shown they are willing to back early-stage clean firm power when the asset makes sense."

Low-Carbon Steel: Certification Frameworks Are Arriving
Wood-derived biocarbon has a long-established niche in steelmaking. Brazil produces roughly 10% of its steel and 30% of its pig iron using charcoal from managed eucalyptus plantations—a proof of concept for biomass as a metallurgical input, if not a direct template for US producers. The plantations measurably lowered groundwater in producer regions of Minas Gerais, and charcoal's mechanical weakness relative to fossil coke has limited the model's reach beyond Brazil.
Current pilot projects use biomass in two roles. As a fuel, industrial trials have demonstrated 10% bio-coal co-injection without operational disruption, with reviews estimating that full replacement could cut blast-furnace CO₂ by around 27% per tonne of hot metal. As a reductant, biocoke is already being demonstrated at Outokumpu's pelletizing plant in Tornio, Finland. ArcelorMittal in Belgium and Tata Steel in India are running biomass pilots at tens of thousands of tonnes per year.
What makes this market worth serious attention now is the certification landscape. The Low Emission Steel Standard issued its first certifications in September 2025. The Global Steel Climate Council's Steel Climate Standard is under stakeholder review. In May 2025, Relae and Microsoft published Criteria for High-Quality Environmental Attribute Certificates in the Concrete and Steel Sectors. These frameworks allow producers to internalize carbon price and environmental attribute certificate (EAC) values, closing the cost gap against fossil coke that has historically constrained biocarbon demand.
Relae worked with Eramet, a global metals company pursuing biogenic materials as a substitute for fossil coke at its Norwegian smelters, to assess high-quality carbon dioxide removal methodologies and chart a path to generating and selling carbon credits from their decarbonization projects. Producers who align their sustainability credentials to these emerging standards now will be better positioned for offtake as commercial-scale demand grows.
"Steelmaker pilots and the first low-carbon steel certifications are opening green-steel offtake to wood pellets, though commercial-scale demand remains limited. The producers that thrive in this market will be those that reliably deliver pellets aligned with high-quality sustainability standards."
—Louisa Brotherson, Hybrid Decarbonization Scientist
Sustainable Aviation Fuel: Mandates Create a Durable Demand Signal
Wood-based SAF is technically feasible via gasification to syngas, followed by Fischer-Tropsch upgrading, a proven chemistry for converting syngas to liquid hydrocarbons. Yet, the commercial challenges are substantial: the International Civil Aviation Organization estimates capital costs exceeding US$1 billion for large facilities, and production costs of US$11–48 per gallon to distillate.
The cautionary case is Fulcrum Bioenergy near Reno, Nevada, which attempted a Fischer-Tropsch process using municipal solid waste and appears to have failed due to a lack of rigorous pre-implementation testing and unrealistic timelines, a reminder that feedstock homogeneity matters enormously, and one area where pellets have a relative advantage.
Two structural dynamics make SAF worth serious attention despite those barriers. First, the European Union's (EU) SAF mandate, starting at 2% of jet fuel supply and ramping to 70% by 2050, carves out cellulosic biomass as the only qualifying feedstock once cooking oil supply is exhausted. The penalty structure in both the EU and UK creates strong demand regardless of SAF price: EU non-compliance penalties run roughly three times the price of SAF, and UK penalties can reach 13 times the cost of the fuel itself. Second, the alcohol-to-jet pathway offers a lower-capital entry point than Fischer-Tropsch, as demonstrated by Project Speedbird, a British Airways and LanzaJet collaboration targeting UK woody residues.
The near-term question is which routes have bankable offtake. Very few do yet, but the mandate structure suggests that window will shift rapidly.
"So far, facilities haven't scaled to the levels required to meet timeline demand. But the EU and UK mandate structures mean buyers are greatly incentivized to purchase SAF even at high prices, rather than pay non-compliance penalties."
—John Dees, Director, Fuels and Industrial Commodities
Domestic Cofiring: Achievable, but Not a Long-Term Anchor
Cofiring biomass with coal to produce electricity or heat is the most immediately achievable option. Most US coal-fired power plants could displace up to 10% of their input energy with raw or torrefied pellets, though plants would likely need fuel handling upgrades. Some state policies, such as Pennsylvania's Alternative Energy Portfolio Standards Act of 2004, support cofiring to meet renewable energy goals. However, there are no federal policies in the US that incentivize cofiring.
The case for cofiring as a long-term market is weak. The US coal fleet has contracted steadily for economic reasons—over 100 gigawatts (GW) of coal-fired capacity retired between 2015 and 2025—and biomass cofiring is unlikely to make a coal plant more cost-competitive. The Greenhouse Gas Protocol's scope 2 guidance does not permit buyers to procure a "strip" of electricity representing the biomass-fired fraction of output from a cofired plant; instead, buyers must accept the average total emissions from the plant in their scope 2 inventory, which limits the value proposition for corporate buyers seeking to demonstrate clean energy procurement.
The more interesting version of this pathway combines cofiring with carbon capture and storage (CCS), a combination that creates a deeper-abatement value proposition and the kind of firm, dispatchable power that corporate buyers increasingly need.
"Cofiring is a proven step toward modest emissions reductions from coal-fired electricity, but it's hard to make the economic case for it when compared to applications that command price premiums for deeper climate abatement."
—A.J. Simon, Director of Industrial Decarbonization
Sustainability Is Now the Qualification Gate
Each of these markets is more discerning about sustainable biomass sourcing than the UK power sector was a decade ago. That shift will not reverse.
US Southeast wood has real potential for high-integrity sustainability credentials, particularly in softwood residues. But it also carries downside risks when sourcing from natural stands. Through work with producers, buyers, and project developers across these markets, we have found that four questions now drive every serious procurement conversation:
- Does the supply chain have verifiable governance and chain-of-custody transparency?
- Does sourcing respect the rights of Indigenous Peoples and local communities?
- Is the wood coming from regions where forest carbon stocks are stable or growing, and not from protected areas or primary forest?
- Is sourced biomass a by-product of non-energy uses, and not the primary silviculture driver?
Producers who can answer yes to all four, and support those answers with data, are more likely to access these emerging markets. Those who cannot will find it harder to compete for offtake.
For a detailed framework on how these principles translate into contract language and certification requirements, see the 2025 Sustainable Forest Biomass Sourcing for CDR: A Buyer's Guide.
The Window Is Open, but Not Indefinitely
The US Southeast wood basket is well-positioned for the markets described here. The infrastructure is in place. What producers still need to build is the market positioning, sustainability documentation, and offtake relationships to go with it.
The producers who move now will have a meaningful head start. Those who wait for certainty may find that the most attractive offtake opportunities have already been structured around someone else's supply.

Frequently Asked Questions
What happens to US wood pellet exports when the UK's new biomass rules take effect?
Starting April 2027, the UK's signed Contracts for Difference agreement caps subsidized biomass generation at a 27% capacity factor, roughly half of today's levels. That's expected to cut total UK pellet demand to about 4.9 million GST a year, leaving only around 1.6 million GST available to US exporters.
Is BECCS for data centers a proven market, or still emerging?
The underlying technology is credible, and the Louisiana Green Fuels project already demonstrates it at commercial scale. However, the deal structure isn't yet proven. No hyperscaler has signed a single contract for both electricity and carbon removal credits from one BECCS plant, so this market is emerging rather than established.
How does low-carbon steel demand compare to sustainable aviation fuel as a market for pellet producers?
Steel offers nearer-term certification frameworks (the Low Emission Steel Standard began issuing certifications in 2025) but limited commercial-scale volume so far. SAF has a stronger long-run demand signal thanks to EU and UK blending mandates and steep non-compliance penalties, but requires far higher capital investment to enter.
What should a wood pellet producer look for when evaluating a new market?
The four sourcing questions that now gate access across all these markets are: verifiable chain-of-custody, respect for Indigenous and local community rights, sourcing from stable or growing forest carbon stocks (not primary forest), and biomass that's a by-product of non-energy uses rather than the primary driver of harvest.
