RESEARCH PAPERS
Net release of CO2 from thawing permafrost soil carbon predicted to occur earlier in this century
Authors: Yi Xi, Philippe Ciais, Dan Zhu, Chunjing Qiu, et al.
Synopsis: Incorporating deep permafrost carbon into an Earth system model, this study finds that thawing soils could release substantially more CO₂ than previously projected. Accounting for deep carbon pools reduces estimated carbon uptake and, under high-emissions scenarios, shifts northern soils from a carbon sink to a carbon source during the 21st century, underscoring the importance of representing deep permafrost carbon in future climate models.
Rock weathering can counteract river CO2 emissions induced by permafrost thaw
Authors: Liwei Zhang, Aaron Bufe, Joshua F. Dean, et al.
Synopsis: Investigating rivers across the Qinghai–Tibet Plateau, this study examines how permafrost thaw influences the balance between CO₂ emissions and carbon uptake from rock weathering. The results show that as permafrost declines, river CO₂ emissions decrease while weathering-driven carbon sequestration increases, with chemical weathering potentially offsetting or even exceeding river CO₂ emissions in heavily thawed regions.:::
Fungi enhance microbial carbon retention in high Arctic fjord sediment
Authors: Juan Carlos Trejos-Espeleta, James A. Bradley, Ömer K. Coskun, Laura M. Wehrmann, Gonzalo V. Gomez-Saez, William D. Orsi
Synopsis: Revealing a previously overlooked carbon storage mechanism, this study shows that marine fungi in Arctic fjord sediments efficiently assimilate and retain dissolved organic carbon as microbial biomass. The findings identify fungal metabolism as an important contributor to long-term carbon storage in seafloor sediments, highlighting its potential role in Arctic carbon sequestration as these ecosystems undergo rapid climate-driven change.
Measuring what matters for carbon removal
Authors: Sara Nawaz, Madison Stevens, Terre Satterfield, Giulia Belotti
Synopsis: Emphasizing the importance of social science, this paper argues that environmental research and monitoring for CDR should account for values, power dynamics, and knowledge systems—not just technical measurements. Drawing lessons from diverse environmental fields, it proposes a framework to help design more robust, equitable, and socially responsible monitoring and evaluation systems for emerging CDR technologies.
Improved latitudinal carbon budgets from global airborne surveys
Authors: Britton B. Stephens, Yuming Jin, Colm Sweeney, Kathryn McKain, Benjamin Gaubert et al.
Synopsis: Using airborne CO₂ measurements from NASA’s Atmospheric Tomography Mission, this study refines global carbon flux estimates and substantially reduces uncertainties in atmospheric inverse models. The analysis identifies a strong northern extratropical land carbon sink and a small tropical land carbon source, challenging current process-based carbon cycle models and highlighting important gaps in understanding global carbon uptake and emissions.
Less is more: how to capture carbon efficiently – lessons from long-term rock weathering and soil development in natural warm temperate ecosystems - Preprint
Authors: Dimitar Z. Epihov
Synopsis: Investigating natural weathering in basalt- and dacite-derived soils, this study examines how ERW stores and loses carbon through different soil pools. The findings suggest that CO₂ removal potential may be overestimated due to cation retention in soils, while smaller basalt applications could accelerate both inorganic carbon sequestration and soil organic carbon accumulation.
Enhanced marine burial of terrestrial organic carbon through the Palaeocene–Eocene Thermal Maximum
Authors: Gordon N. Inglis, Jordon D. Hemingway, Richard G. Stockey, et al.
Synopsis: Drawing on evidence from the Paleocene–Eocene Thermal Maximum, this study shows that burial of terrestrial organic carbon in marine sediments increased dramatically during a period of rapid global warming. The findings suggest this process acted as an important long-term carbon sink and climate feedback, highlighting a mechanism that is currently missing from many paleoclimate and carbon cycle models.
Agricultural liming is a large carbon sink in the Mississippi River Basin - Preprint
Authors: Tim Jesper Suhrhoff, Christopher Reinhard, Yoshiki Kanzaki, Samuel Shou-En Tsao et al.
Synopsis: Challenging conventional assumptions, this study finds that agricultural liming has functioned as a net carbon sink rather than a CO₂ source in the Mississippi River Basin over the past century. By combining historical data with reactive transport modeling, the authors estimate that most of lime’s carbon removal potential has already been realized, suggesting optimized soil pH management can enhance crop yields, improve soil health, and reduce agricultural greenhouse gas emissions.
Delayed climate benefits and toxicity risks could hinder the sustainable deployment of enhanced weathering - Preprint
Authors: Selene Cobo, Gonzalo Guillen Gosalbez
Synopsis: Reassessing enhanced weathering using empirical data, this study finds that climate benefits may be delayed by about 11 years due to emissions from rock mining, transport, and processing. It also identifies potential long-term toxicological risks from heavy metal releases, particularly zinc from basalt, suggesting that carbon crediting and large-scale deployment should await stronger evidence and prioritize non-agricultural sites until food safety risks are better understood.
Direct Air Capture Technologies: Innovations, Integration, and Pathways to Scale
Authors: Chuhan Fu, Wenkang Deng, Yalou Guo, Zhifu Liu, et al.
Synopsis: Reviewing recent advances in DAC, this paper evaluates the chemistry, engineering, energy use, costs, and environmental impacts of leading carbon capture technologies. It highlights the potential of integrating DAC with renewable energy and industrial waste heat to improve efficiency and scalability, while outlining key technical and economic challenges that must be addressed for widespread deployment.
Microbial-mediated soil organic carbon sequestration under biochar application in Chinese agricultural soils
Authors: Gehao Zhang, Yang Liao, Jianzhao Wu, Kangyu Wang, Yufei Zhang, Zhouping Shangguan, Yan Fang & Lei Deng
Synopsis: Focusing on the role of soil microbes, this study analyzes hundreds of biochar experiments across China to assess long-term soil carbon sequestration. Biochar significantly increased soil organic carbon stocks, but changing microbial communities reduced carbon retention efficiency over time. The findings suggest biochar application strategies should be adapted to maintain microbial conditions that support sustained carbon storage.
Simulating enhanced ocean alkalinity experiments in a high-latitude fjord using nested ROMS simulations coupled with MARBL biogeochemistry - Preprint
Authors: Ulla K. Heede, Matthew C. Long, Alicia Karspeck, et al.
Synopsis: Evaluating the C-Star regional ocean model, this study demonstrates its ability to simulate OAE field trials in an Icelandic fjord. The model accurately reproduces circulation, tracer transport, and OAE-induced chemical changes, showing that seasonal conditions and winds strongly influence CO₂ uptake and alkalinity dispersal. The findings support C-Star as a valuable tool for designing and interpreting future OAE research and field experiments.
Accounting Methods Dictate Carbon Removal Credit Integrity and Outcomes - Preprint
Authors: Corinne Scown, Sarah Nordahl, Evan Sherwin, Caspar Donnison, Kimberley K. Mayfield
Synopsis: Comparing two carbon accounting approaches, this paper examines how life-cycle assessment (LCA) and the net flux framework (NFF) affect the calculated performance and economics of CDR projects. The analysis shows that accounting choices can significantly alter CDR eligibility and revenues, highlighting the need for clear methods that distinguish genuine carbon removal from emissions reductions and offsets.
Scaling Up Carbon Removal: Policy Challenges and Plausible Future Pathways
Authors: Farzana Enam Rasna
Synopsis: Looking ahead to the future of CDR, this paper develops three governance scenarios based on current trends, emerging signals, and policy, technological, and social drivers. Rather than making predictions, it explores possible pathways for global CDR governance, identifying opportunities and risks while emphasizing equity, international cooperation, and the differing needs and capacities of the Global North and Global South.
Global quantification of the eco-hydrological co-benefits of soil carbon sequestration
Authors: Inne Vanderkelen, Marie-Estelle Demory, Sean Swenson, et al.
Synopsis: Assessing the hydrological impacts of soil carbon sequestration, this study finds that increasing soil organic carbon enhances water retention in plant rooting zones, reduces runoff, and alleviates water stress, particularly in arid, sandy croplands. Although the global effects are modest, the results highlight measurable eco-hydrological co-benefits that can improve ecosystem resilience while supporting climate change mitigation.
An ecosystem of carbon dioxide removal reviews – part 2: CO2 removal via blue carbon ecosystems
Authors: Christian Rischer, Ignacio Saldivia Gonzatti, et al.
Synopsis: Synthesizing evidence from more than 2,600 studies, this systematic review evaluates the contribution of blue carbon ecosystems—including mangroves, seagrasses, salt marshes, and macroalgae—to CDR. The authors conclude these ecosystems could make a meaningful contribution to climate mitigation but require improved carbon accounting, stronger policy integration, and incentive frameworks that support both carbon storage and ecosystem co-benefits.
The influence of speed and scale of carbon dioxide removal on overshoot peak temperature and duration - Preprint
Authors: Nina Rynne, Michael Bode, Melanie E Roberts, Ryan F Heneghan
Synopsis: Using a climate-economic model across Shared Socioeconomic Pathways, this study examines how the speed and scale of CDR deployment influence temperature overshoot beyond the 1.5°C target. The results show that rapid deployment is the dominant factor in limiting peak warming and overshoot duration, while slower rollout leads to substantially higher and longer-lasting temperature exceedance.
Pollution or protection? The International Tribunal for the Law of the Sea’s advisory opinion on climate change and its relevance for marine carbon dioxide removal (mCDR)
Authors: Miranda Boettcher, Rakhyun E. Kim
Synopsis: Analyzing the 2024 ITLOS advisory opinion on climate change, this paper explores its implications for governing marine carbon dioxide removal (mCDR). While the ruling clarifies state responsibility for protecting oceans from CO₂ pollution, it leaves ambiguity over whether mCDR should be classified as pollution or protection, creating scope for divergent political interpretations in future ocean governance and climate policy.
Nature-positive carbon dioxide removal (NPCDR): A governance framework for integrating carbon integrity and ecosystem performance in EU climate policy
Authors: Behrouz Gholamahmadi
Synopsis: Introducing the concept of Nature-Positive Carbon Dioxide Removal (NPCDR), this paper proposes a governance framework that jointly evaluates carbon removal performance and ecosystem health. Building on emerging EU policy initiatives, it argues that carbon durability, biodiversity, soil condition, and hydrological function should be treated as integrated metrics, enabling carbon removal strategies that align climate mitigation with broader environmental restoration goals.

Green-Hushing, Safe Harbors, and Who Actually Owns a Carbon Credit - with Dr Ruth Dagan | The CDR Policy Scoop
“In this episode of The CDR Policy Scoop, Sebastian Manhart sits down with Dr. Ruth Dagan, Senior Partner and Head of Environment & Climate Change at Herzog Law, and Co-Chair of the IETA Legal Working Group, to cover two legal challenges that are quietly suppressing corporate demand for carbon credits.
The first is litigation risk. Since 2022, climate washing claims have increased by seventy percent globally, with around 160 cases on the books and fifty-four relating specifically to carbon credit offsets. Apple’s carbon neutral Watch campaign was lost in Germany and only tentatively won in the US. The upshot is that many companies are choosing to say nothing about their climate action at all. Ruth calls this green-hushing, and argues it is actively draining demand from the voluntary carbon market.
The conversation covers the two regulatory responses now taking shape: the EU Empowering Consumers Directive, coming into force in September, which blacklists product-level carbon neutrality claims outright, and California’s AB 1911, which proposes the opposite, a safe harbor that would actively protect companies using high-integrity credits. Ruth outlines the work being led by IETA and the Coalition to Grow Carbon Markets, now backed by eleven governments.
The second challenge is more fundamental: most carbon credit registries, including PACM, include explicit disclaimers that they make no legal statement about who actually owns the credits in an account. Ruth explains how this came to be, what it means for institutional investment, and how the Unidroit project, due to conclude in early 2027, offers a route to resolution.”
Inside the ISO Net Zero Standard - with Delia Meth-Cohn | The CDR Policy Scoop
“In this episode of The CDR Policy Scoop, Sebastian Manhart sits down with Delia Meth-Cohn, Co-founder of Rethinking Removals, who has been part of the ISO Net Zero Aligned Organization Standard working group from its very first meeting, two years ago.
The conversation opens on why Delia got involved, recruited by the British Standards Institute to make sure removals expertise was in the room from the start. She explains what makes ISO structurally different from SBTi: where SBTi is a voluntary framework for leading, self-selecting companies, ISO is built to be globally applicable, rooted in national standards bodies and the WTO framework, and designed to accommodate countries with different net zero end dates, from Europe’s 2050 to China’s 2060 and Saudi Arabia’s 2070.
The discussion gets to the heart of what the standard actually does on removals: it makes the implicit removals target in net zero frameworks explicit. Companies setting a long-term reduction target must treat whatever remains as their “anticipated residual emissions”, and that figure becomes a removal target they are required to plan toward, with a validated first milestone within five years. Delia is clear that flexibility is intentional: the strategy can involve a portfolio of credits, removals within operations, or value chain approaches, so long as the trajectory is defensible and verified.
Sebastian pushes on the question of ambition and comparability: can two companies with very different removal strategies both receive the same ISO certification? Delia acknowledges the tension and closes on a call to action: the standard is currently in public consultation, comments feed through national standards bodies into the final draft, and this is the CDR community’s real window to push back on anything that falls short. The final standard is expected by mid-2027.”
When will insetting work for carbon dioxide removal?—w/ Tom Mills, Stripe Climate Fellow (former) | Reversing Climate Change
“Everyone knows about offsetting. But what about insetting? Surely, that’s easier. If only we could define it...
In this episode of Reversing Climate Change, host Ross Kenyon sits down with Tom Mills to dig into the physical reality of carbon dioxide removal (CDR) and its intersection with heavy industry, mining, and global agricultural supply chains.
Drawing from his experience working in mining governance across Africa and South Asia, Tom shares how the physical, logistical, and geopolitical challenges of heavy industry perfectly parallel the hurdles facing the scaling of CDR today. The conversation explores Tom’s journey into carbon removal while living in India, where he realized how the region’s unique geology and agricultural needs make it an ideal landscape for scalable climate solutions like biochar and enhanced rock weathering (ERW).”
Why Forest Cover Tells the Wrong Story: Measuring Carbon from Space — Marco Albani | This Week in Carbon
“In this episode of This Week in Carbon, hosts Edward Smith and Rene Velasquez sit down with Marco Albani, Co-founder and Co-CEO of Chloris Geospatial. Marco has spent his career at the intersection of forestry, climate science, and carbon markets - from building the forestry portion of McKinsey’s Marginal Abatement Cost Curve, to running the Tropical Forest Alliance, to co-founding Chloris with his former forestry classmate Alessandro Baccini, the scientist whose spaceborne LIDAR research underpins what the company does today.This is a conversation about what it actually takes to measure forest carbon at scale, and why the tools the industry has relied on for decades aren’t up to the job.Key topics covered:- Why measuring forest cover is the wrong metric, and why carbon stock is what actually matters for climate outcomes- The fundamental problem with the definition of “forest” and how it creates blind spots in policy and carbon accounting- How Chloris built a carbon time series going back to the year 2000 and the technical limitations that make historical data so hard to reconstruct- Why there is no such thing as “direct measurement” of biomass, and what that means for how we should think about field data vs. remote sensing- The cost reality of satellite data: a $17 million quote for imagery on a project worth $3 million in credits- The three types of customers Chloris serves: carbon market infrastructure (Verra, MSCI, Equitable Earth), project developers under VM47, and corporations tracking Scope 3 supply chain emissions- The Geo AI wave: what foundation models like Google’s Alpha Earth get right, where they fall short, and why accuracy assessment is the missing piece- Who should be building the test beds needed to validate these new tools and why philanthropic capital is the right fit- How better measurement translates into more capital flowing to forests, and what consistent measurement across project, subnational, and national scales means for Article 6- Why humility matters as powerful algorithms replace human judgment in landscape decisionsA technically rich, intellectually honest conversation about the infrastructure the carbon market needs to actually work.”

Direct air capture Illuminating and filling the gaps | CanCO2Re Initiative
“Direct air capture (DAC) has received increasing attention as a method to reduce atmospheric CO2 and achieve net-zero commitments. Despite industry momentum and media attention, core questions around the engineering science of DAC remain underexplored.
In this webinar, researchers from the CanCO2Re DAC team pull back the curtain on what the science tells us about how DAC works, where the knowledge gaps are, and why forming an informed opinion on DAC requires access to data that, in many cases, doesn’t yet exist. They’ll also offer a glimpse into the foundational research underway in Canada to fill these gaps.”

How I Would Build a Corporate Carbon Credit Strategy From Scratch Today | Senken
“I’ve watched dozens of large European corporates get carbon credit strategy wrong. Companies spending 7 figures on credits that turned out to be useless for SBTi submission because nobody checked the methodology against the rules first.
The pattern is always the same: people start shopping before they have done the foundational work.
In this video I walk through the exact 14-step framework I would use today to build a corporate carbon credit strategy from scratch, across 5 phases.”
The Carbon Removal Potential of Rubberwood | Beston_ReGreen
“The rubber industry has a mature latex and timber value chain, yet it has long overlooked the potential of processing residues. A large volume of rubberwood waste remains underutilized and fails to achieve a circular resource loop.
With voluntary carbon markets increasingly demanding durable carbon removal, converting waste into biochar has emerged as a high-quality solution for sustainable development within the industry chain.
Compared to other biomass sources, rubberwood biochar projects perfectly avoid two major challenges:
Compliance: Under EU regulations, natural rubber is classified as an agricultural product, and rubber plantations are considered agricultural land. Tree renewal falls under sustainable management, posing no risk of deforestation, thereby easily passing international carbon audits.
Supply stability: Rubber trees have a 25–30-year growth cycle, and routine replanting enables precise forecasting of raw material supply over the next decade. The dual value of rubber trees—latex and timber—ensures that raw material supply is not vulnerable to fluctuations in a single market.
This technology converts easily perishable carbon into solid carbon that can be sequestered for centuries, achieving durable carbon removal while improving soil quality and enhancing plantation productivity.
Amid the surge in demand for high-quality carbon credits, rubberwood biochar, with its compliance, stability, and scalability, is emerging as a highly promising project in the carbon market.”
Financing Models and the Evolution of CDR Credits in Carbon Markets | Cdr Türkiye
