RESEARCH PAPERS
Rock powder amendment in enhancing plant-mediated carbon sequestration
Authors: Matthew Chekwube Enebe, Richard W. Griffin, Javad Barouei, Ram Ray
Synopsis: Rock powder amendments could play a larger role in carbon removal than previously recognized by improving plant growth while increasing both organic and inorganic carbon storage in soils. This review examines how ERW boosts nutrient availability, strengthens photosynthetic carbon uptake, and promotes long-term carbon sequestration. Despite its potential benefits for climate mitigation, soil fertility, and food security, researchers highlight persistent uncertainties and practical barriers that could limit large-scale deployment.
Analysing policy signals from the US, EU and UN regulations for the deployment of marine carbon dioxide removal
Authors: Coline Seralta, Emma Jagu Schippers, Yannick Perez & Pascal Da Costa
Synopsis: Governance of mCDR is highly fragmented across major jurisdictions, creating uncertainty around its future deployment. A review of regulatory and policy documents from the United States, European Union, and United Nations finds divergent approaches: the US tends to support regulatory pathways that enable research and innovation, the EU provides mixed or ambiguous signals, while UN frameworks generally emphasize restrictions on deployment. The study highlights how scientific uncertainty and political disagreement jointly shape the evolving global governance landscape for ocean-based carbon removal.
Carbon Removal Using Geological Resources and Mine By-Products
Authors: Liam A. Bullock & Juan Alcalde
Synopsis: Geochemical CDR is emerging as a scalable approach that uses natural and industrial alkaline materials to permanently store atmospheric CO₂ as bicarbonate or carbonate minerals. The strategy relies on enhanced weathering of silicate rocks and industrial by-products such as mine tailings and steel slags, with efficiency driven by factors like particle size, climate conditions, and biological activity. While the approach offers potential gigaton-scale removal and co-benefits for resource circularity and soil health, challenges remain around monitoring, net carbon accounting, environmental risks, and regulatory alignment.
Natural forest expansion is a larger carbon sink than secondary forests in moist tropics
Authors: Yihang Zhang, Viola H. A. Heinrich, Clément Bourgoin, et al.
Synopsis: Natural forest expansion into previously unforested land may represent a larger tropical carbon sink than previously recognized. Combining satellite observations with spaceborne LiDAR data, researchers found that naturally expanding forests store slightly more above-ground carbon than secondary forests and show comparable carbon accumulation rates, particularly in the Americas. The study highlights natural forest expansion as an overlooked source of climate mitigation potential, alongside protecting old-growth forests and supporting forest regeneration.
Photosynthetic optimum temperature plays a minor role in the increase of terrestrial carbon uptake from 2000 to 2019
Authors: Chongyang Xu, Hongyan Liu, Dan Yakir, et al.
Synopsis: Rising temperatures are increasing ecosystem carbon uptake, but not for the reasons scientists previously assumed. Analysis of the past two decades shows that while maximum photosynthesis has increased globally, the temperature at which photosynthesis performs best has remained relatively unchanged. Instead, researchers find that changes in water use and vegetation structure play a much larger role, suggesting future carbon storage projections must account more carefully for ecosystem responses to water stress and changing environmental conditions.
Quantification of sequestered fossil-derived CO₂ in cementitious materials and its atmospheric contamination using carbon isotope measurements
Authors: Ippei Maruyama, Ryusei Igami, Ryo Kurihara, et al.
Synopsis: Accurately measuring how much CO₂ cement-based materials capture remains challenging because atmospheric carbon can mix with targeted carbon sources during carbonation. This study combines carbon isotope analysis with accelerated carbonation experiments to distinguish fossil-derived CO₂ from atmospheric contamination in cement paste. Researchers propose a framework for source-specific measurement of CO₂ fixation, potentially improving verification methods and supporting more reliable labeling and assessment of carbon-captured construction materials.
Biochar co-benefits are valued in the voluntary carbon market
Authors: Medilė Jokubė, Matti Hyyrynen, Sampo Pihlainen & Kari Hyytiäinen
Synopsis: Market demand for sustainable development benefits appears to influence pricing in the biochar carbon removal market, according to new analysis of voluntary carbon market transactions through 2024. Researchers found biochar carbon credit prices rise as the number of claimed co-benefits increases, with economic co-benefits associated with higher prices while environmental claims tend to correspond with lower valuations. The findings suggest stronger auditing of co-benefit claims may be necessary to maintain credibility and integrity in emerging carbon removal markets.
Hybrid biophysical systems for atmospheric CO2 capture
Authors: Peter Agbo, Joseph O Varghese, Ryan K Henning, Jacob S Kanady and Ashwin Ram
Synopsis: Harnessing engineered microorganisms could offer a new route to lower-cost carbon removal by accelerating one of the key bottlenecks in CO₂ capture. This perspective explores the use of cyanobacteria engineered to display carbonic anhydrase enzymes on their outer membranes, creating self-refreshing biological catalysts for direct air and ocean capture systems. Researchers suggest such systems could reduce reliance on purified enzymes while potentially improving the scalability of mineralization-based carbon removal approaches.
Bridging carbon removal time lags in agricultural enhanced weathering via methane emission reduction
Authors: Noah J Planavsky, Beck J Woollen, Ella Milliken, Yoshiki Kanzaki, Mojtaba Fakhraee, David J. Beerling and Christopher T Reinhard
Synopsis: Pairing enhanced weathering with methane removal could help address one of carbon removal’s key challenges: delayed climate benefits. This perspective argues that while enhanced weathering offers durable carbon removal and agricultural co-benefits, the lag between deployment and resulting radiative cooling complicates its use for offsetting emissions. Researchers propose coupling enhanced weathering with enhanced methane destruction to create more immediate and continuous climate impacts, potentially improving carbon credit frameworks.
Increased yields for smallholder farmers from enhanced rock weathering
Authors: Jacob S Jordan, Tom M.D. Mills, Isha Jain, Dilip Patidar, et al.
Synopsis: ERW could provide a pathway for increasing crop yields while supporting carbon removal in smallholder farming systems. Analysis of 216 rice farmers across 42 villages in India found median yield increases of 24.7% alongside household income gains exceeding 20%, suggesting productivity improvements without relying solely on synthetic fertilizers. Researchers argue carbon finance could help offset deployment costs, potentially improving the scalability of low-carbon agricultural intensification.
The Importance of Scale in the Future of Mangrove Blue Carbon Under Sea-Level Rise
Authors: A. P. Iwantoro, D. H. Urrego, D. Xie, A. P. Nicholas, et al.
Synopsis: Mangrove forests may become less reliable long-term carbon sinks under rising sea levels despite showing localized increases in carbon accumulation. Using a new eco-carbon-morphodynamic model, researchers found that sea-level rise can reduce landscape-scale carbon storage by limiting mangrove expansion, increasing erosion, and triggering vegetation loss. The findings suggest that local gains in carbon sequestration may mask broader ecosystem vulnerability, highlighting the importance of landscape-scale assessments for future blue carbon projections.
Environmental trade-offs of CO2 mineralization cell by life cycle assessment
Authors: Xinchen Song, Yunpeng Wang, Wenchuan Jiang, Zaijie Wang et al.
Synopsis: Converting industrial waste into carbon-storing materials could deliver larger climate benefits than previously assumed, according to a new life cycle assessment of CO₂ mineralization cells (CMC). Researchers found mineralizing 1 tonne of CO₂ using carbide slag generated substantial net emissions reductions while producing high-purity calcium carbonate and electricity as co-products. The analysis suggests environmental benefits extend beyond direct carbon storage, with system design, energy sources, and deployment conditions strongly influencing performance.
Evaluation of the Mechanical Performance and Carbon Sequestration in Ferro-Rock Sustainable Concrete Through Partial Cement Replacement and Controlled CO2 Curing
Authors: Seleem S. E. Ahmad, Ahmed M. Elshirbeny, Ahmed A. Elshami, et al.
Synopsis: Ferro-Rock concrete could offer a carbon-negative alternative to conventional cement by using iron-rich waste materials and CO₂ curing to form iron carbonate binding phases. Experimental results show limited cement replacement levels (5–10%) improved compressive, flexural, and tensile strength compared with conventional mixes, while fully cured Ferro-Rock materials sequestered up to 11% CO₂ by weight. Researchers suggest the approach shows promise for lower-carbon construction, although higher replacement levels significantly reduced material performance.
Investigating the Influence of Alkali Chloride Salts and Hydration on the Direct Air Capture Capacity of Polyethylenimine Films with Quartz Crystal Microbalance and Infrared Spectroscopy
Authors: Kayley Winata, Kayli Kuk, Christopher L. Soles, Avery E. Baumann
Synopsis: New research suggests salt additives could improve the performance of DAC materials by controlling how much water and CO₂ they absorb under different humidity conditions. Using aminopolymer sorbents and multiple experimental techniques, researchers found that salts with different cations alter water uptake and influence the formation of CO₂ capture products, ultimately changing capture efficiency. The findings could help optimize sorbent materials for more effective carbon removal systems.
Opposing Carbon Dioxide Removals and emissions reductions confuses mitigation policies - Preprint
Authors: Romain Pirard, Kenneth Möllersten
Synopsis: Separating climate mitigation into carbon removal and emissions reduction categories may create more problems than it solves, according to a new assessment of carbon market methodologies. Researchers argue the distinction is often inconsistent, overlooks key economic considerations, and fails to capture the hybrid nature of many mitigation activities. Instead, the study proposes prioritizing interventions based on characteristics such as permanence, cost, leakage risks, co-benefits, and overall mitigation effectiveness rather than rigid categories.
Experimental Evaluation of Three Clay Minerals for CO2 Mineralisation: New Pathways for Carbon Sequestration
Authors: M. Abdalqadir, S. Rezaei Gomari, and D. Hughes
Synopsis: Abundant clay minerals could represent an overlooked pathway for permanent carbon removal through mineral carbonation. Experimental testing of kaolinite, montmorillonite, and illite found all three materials captured measurable amounts of CO₂, with illite showing the strongest performance due to its higher calcium content and montmorillonite benefiting from favorable surface properties. The findings suggest certain clay-rich materials could expand the range of feedstocks available for mineral carbonation-based carbon sequestration.
Species-specific allometric indicators and carbon sequestration potential in mixed agro-forestry plantation systems - Preprint
Authors: Adikant Pradhan, S. K. Nag, T. Chnadrakar, S. Malaiya, K. S. Keram, D. Kerketta, Amar Nath, Sweekruta Mohapatra
Synopsis: Species selection and planting density play a major role in determining how much carbon agroforestry systems can store, according to new research evaluating five common plantation species. While eucalyptus showed the highest carbon storage per tree, cashew plantations delivered the greatest carbon sequestration per hectare due to higher planting densities. The findings suggest species-specific growth patterns and allometric models could improve carbon accounting and ecosystem monitoring in agroforestry systems.
A comprehensive design framework for nature-based solutions projects focused on carbon dioxide removal: A systematic literature review of approaches, models and tools
Authors: Combe Mathieu, Briard Tristan, Harambat Fabien, Segonds Frédéric, Jean Camille
Synopsis: Designing Nature-based Solutions (NbS) for carbon dioxide removal requires more detailed and structured methodologies than current standards provide. A review of 118 studies identifies a multi-step framework for NbS design, including definition, assessment, optimization, and implementation, with supporting tools such as carbon stock assessments, ecosystem service evaluation, and dynamic carbon modeling. The analysis highlights growing use of machine learning and calls for more systematic, resilient design approaches to improve real-world NbS effectiveness.
Ocean iron fertilization for carbon dioxide removal and climate change mitigation
Authors: Santiago Hernández-León & Eric Lichtfouse
Synopsis: Removing carbon dioxide from the atmosphere may become increasingly necessary alongside emissions reductions, prompting renewed attention toward large-scale carbon removal approaches such as ocean iron fertilization. This perspective argues that natural carbon sinks operate too slowly to counter rising atmospheric CO₂ concentrations and presents ocean iron fertilization as a potentially scalable approach for enhancing carbon storage in the deep ocean. The authors note, however, that such interventions remain controversial due to ecological uncertainties and potential risks.

The State of CDR 2026: The CDR Policy Scoop Verdict | The CDR Policy Scoop
“In this episode of The CDR Policy Scoop, Sebastian Manhart and Eve Tamme dig into the highly anticipated third edition of the State of CDR Report.
At 300 pages and 75-plus authors, this edition is the most comprehensive mapping of the CDR landscape to date. Sebastian and Eve don’t attempt to walk through the headlines they go deeper, pulling out the findings that stood out, challenged assumptions, or raised new questions.
The conversation opens on vocabulary: the report’s case for retiring “natural versus technological” in favour of “conventional versus novel”, and why that framing matters for how CDR is perceived by the public. It then turns to one of the report’s most important, and most easily misread, numbers: the 2.2 gigatons of global CDR, of which 99.9% is conventional and 2.1 megatons is novel. Sebastian unpacks why gross versus net removals is not a semantic debate, and why the two figures are measuring fundamentally different things.
From there, they cover the gap: what NDCs and long-term strategies actually say (and don’t say) about CDR, why a new wave of national climate plans arrived with almost no additional detail on removals, and what the report’s modelling implies about how much CDR net zero will actually require, with the average across scenarios now sitting at 16% of mitigation effort, not the 10% commonly cited. They also take a hard look at the 2030 outlook: the report’s layered approach to projections, why the 2020 prediction of 11 megatons by 2025 became 2, and what company announcements of 42 megatons actually mean in practice.
The episode closes on what the next decade of CDR delivery really looks like: biomass-based methods dominating through 2030, a CDR funding share of just 2.6% of all climate tech, and a shout-out to CDRjobs, which gets its first dedicated section in the report, for contributing workforce data to the ecosystem.”
Taking Stock: The State of CDR - Fireside Chat with Oliver Geden | The CDR Policy Scoop
“Recorded live at the Negative Emissions Platform (NEP) event in June 2026, this fireside chat brings Sebastian Manhart together with Oliver Geden for a rapid-fire sweep through the state of CDR policy.
Oliver Geden is Head of the Research Cluster on Climate and Energy Policy at SWP (the German Institute for International and Security Affairs), Vice Chair of IPCC Working Group Three, and a member of the executive team of the State of CDR Report. He co-authored Chapter Five on policy in the report’s third edition, published the week this conversation was recorded.
Together they dig into the questions that matter, the numbers that mislead, and the politics underneath both. In 30 minutes they cover a lot of ground: the policy sequencing debate, what the 16% CDR share of global mitigation effort actually means, and which countries are pulling ahead.
Oliver walks through why over 100 countries now have net zero targets, yet novel CDR features in only two NDCs through to 2035, Australia and the UK, and in around one-third of long-term strategies for 2050. He draws on his IPCC experience to explain the shift in how CDR has been framed in intergovernmental negotiations: from “scenarios suggest you’ll need it” to “you cannot reach net zero without it.” That shift forecloses the option of treating CDR as an optional add-on, but it hasn’t yet translated into concrete national planning at scale.
The conversation gets into the weeds on EU policy design: the complexity of introducing national durable removal targets within the pillar system, the tension in the international credits debate between what the text says and what policymakers are actually trying to achieve, and a concept Oliver introduces that is worth holding onto: “politically hard to abate.” The episode closes on a question that would have felt out of place a year ago: what the war in Iran does to climate and CDR policy ambition, and Oliver’s answer is, characteristically, clear-eyed.”
