RESEARCH PAPERS
Carbon dioxide removal from triethanolamine solution using living microalgae-loofah biocomposites
Komkhum, T., Sema, T., Rehman, Z. U., & In-na, P. (2025). Carbon dioxide removal from triethanolamine solution using living microalgae-loofah biocomposites. Scientific Reports, 15(1), 1-14.
Synopsis: Amine solvents efficiently capture CO2 but require high energy for regeneration. This study explores an alternative approach using living microalgae-loofah biocomposites to enhance CO2 removal from triethanolamine (TEA) solutions. Immobilized Scenedesmus acuminatus outperformed suspended cultivation, achieving CO2 removal rates 3–5 times higher over 28 days. The findings highlight the potential of integrating biological and chemical processes for CO2 capture, though pilot-scale studies are needed for validation.
Spatio-temporal dynamics of future aboveground carbon stocks in natural forests of China
Zhang, Y., Cheng, K., Yang, Z., Chen, Y., Yang, H., Ren, Y., ... & Guo, Q. (2025). Spatio-temporal dynamics of future aboveground carbon stocks in natural forests of China. Forest Ecosystems, 100293.
Synopsis: Natural forests are vital carbon sinks, and China has expanded its forest area through conservation efforts. This study estimates China’s natural forests could sequester up to 10.46 ± 0.11 Pg C by 2060, though the sequestration rate will decline over time. Spatial analysis shows young forests in temperate regions will see the largest gains, while mature forests in the Qinghai-Tibet Plateau will have minimal increases. Protecting mature forests and restoring young forests is key to maintaining carbon sequestration.
Which plant traits increase soil carbon sequestration? Empirical evidence from a long-term poplar genetic diversity trial
Field, J. L., Sloan, B. P., Craig, M. E., Calloway, P., Ottinger, S. L., Mead, T., ... & Mayes, M. A. (2025). Which plant traits increase soil carbon sequestration? Empirical evidence from a long-term poplar genetic diversity trial. bioRxiv, 2025-02.
Synopsis: Breeding or engineering crops to boost soil organic carbon (SOC) storage could enhance land-based carbon removal. This study analyzed 24 Populus trichocarpa genotypes in a 13-year-old common garden, revealing significant genetic influence on SOC fractions. Root elemental content, particularly aluminum (Al), boron (B), and magnesium (Mg), strongly correlated with mineral-associated organic matter. Findings suggest targeting root chemistry in breeding programs could optimize SOC sequestration, advancing climate mitigation strategies.
Natural sequestration of carbon dioxide is in decline: climate change will accelerate
Curran, J. C., & Curran, S. A. Natural sequestration of carbon dioxide is in decline: climate change will accelerate. Weather.
Synopsis: The terrestrial biosphere's natural CO2 sequestration peaked in 2008 and is now declining by 0.25% per year, causing atmospheric CO2 to rise faster than before. Currently, CO2 increases by +2.5 ppm annually, compared to a potential +1.9 ppm if sequestration had remained at 1960s levels. This decline accelerates climate change, highlighting the urgent need to restore biodiversity and ecosystem services to strengthen natural carbon removal and mitigate the climate crisis.
A comprehensive review of life cycle assessments of direct air capture and carbon dioxide storage
Eke, V., Sahu, T., Ghuman, K. K., Freire-Gormaly, M., & O'Brien, P. G. (2025). A comprehensive review of life cycle assessments of direct air capture and carbon dioxide storage. Sustainable Production and Consumption.
Synopsis: This review examines Life Cycle Assessments of Direct Air Capture and Carbon Storage technologies, assessing their environmental impact and carbon removal effectiveness. While DACCS is a promising climate solution, LCA studies show wide variability in efficiency and resource demands. Solid sorbents reduce emissions by 640 kg CO₂-eq/t CO₂, while liquid sorbents achieve 560 kg CO₂-eq/t CO₂, with system efficiencies of 56–64%. Environmental trade-offs include high water use (1–12 tons per ton CO₂), land requirements (85–4450 km²), and particulate emissions (~180 kt annually). The study underscores the need for standardized LCAs and improved system design to balance carbon removal with sustainability.
Global warming may turn ice-free areas of Maritime and Peninsular Antarctica into potential soil organic carbon sinks
de Mello, D. C., Francelino, M. R., Moquedace, C. M., Baldi, C. G., Silva, L. V., Siqueira, R. G., ... & Schaefer, C. E. (2025). Global warming may turn ice-free areas of Maritime and Peninsular Antarctica into potential soil organic carbon sinks. Communications Earth & Environment, 6(1), 143.
Synopsis: This study using machine learning and field data from 2800 Antarctic sites predicts that climate change will increase soil organic carbon stocks in Maritime and Peninsular Antarctica’s ice-free areas. SOC stocks in the 0–30 cm layer could nearly double under warming scenarios, driven by temperature, precipitation, and net primary productivity. However, the extent of this carbon sink depends on existing SOC content and soil depth, highlighting the region’s evolving role in global carbon dynamics.
Modeling the Impact of Direct Air Capture on Forest Biomass and Population Dynamics
Verma, P., Kaur, J., Arora, M. S., Dogar, M. M., & Purohit, S. (2025). Modeling the Impact of Direct Air Capture on Forest Biomass and Population Dynamics. Earth Systems and Environment, 1-21.
Synopsis: This study presents a mathematical model integrating DAC with climate variables. Stability analysis shows DAC stabilizes CO2 levels, while emissions destabilize them. Using historical data, the model is calibrated, and an optimal cost-effective DAC deployment strategy is proposed, aiding climate policy decisions.
Applications, potential, and challenges of biochar in carbon sequestration
Wang, Y. (2025). Applications, potential, and challenges of biochar in carbon sequestration. Highlights in Science, Engineering and Technology, 125, 23-27.
Synopsis: Biochar is a promising carbon sequestration tool with ecological benefits like soil improvement and greenhouse gas reduction. This paper details biochar’s types, properties, preparation methods, and sequestration mechanisms. Challenges in industrial applications are discussed, along with future optimization strategies, including raw material selection, process improvements, and cost reduction. Advancing biochar technology can enhance its role in climate change mitigation.
Review on in-situ CO2 mineralization sequestration: mechanistic understanding and research frontiers
Ye, H., Liu, Q., Bao, Q., Wang, Z., Xie, Y., Michelle, T., ... & Xian, C. (2025). Review on in-situ CO2 mineralization sequestration: mechanistic understanding and research frontiers. International Journal of Coal Science & Technology, 12(1), 15.
Synopsis: In-situ CO2 mineralization offers permanent carbon storage, surpassing conventional geological methods. Despite its potential, uncertainties remain in geochemical interactions, reaction kinetics, and pore blockage risks. Pilot projects in Iceland and the U.S. confirm feasibility, but deployment is still early. This review examines mineralization mechanisms, influencing factors, and research progress, highlighting the need for reliable capacity evaluation and deeper understanding of CO2 conversion kinetics.
Impact of direct air capture process flexibility and response to ambient conditions in net-zero transition of the power grid
Arwa, E. O., & Schell, K. R. (2025). Impact of direct air capture process flexibility and response to ambient conditions in net-zero transition of the power grid. Applied Energy, 386, 125549.
Synopsis: This study highlights the importance of incorporating realistic DAC performance data into capacity expansion models for net-zero power grids. It finds that assuming a constant DAC capture rate underestimates the required costs, DAC capacity, and renewable energy needs. When accounting for ambient environmental conditions, meeting net-zero targets requires 22.2% more DAC capacity, along with 2.5% more wind and 1.9% more solar capacity. However, integrating DAC flexibility—such as material storage in silos—reduces overall costs by lowering the necessary generation expansion. These insights improve the accuracy of net-zero transition planning and climate mitigation strategies.
Reactive transport simulation of organic and inorganic carbon cycling following carbon dioxide sorption onto soil amendments in drylands
Helmrich, S., Ringsby, A. J., & Maher, K. Reactive transport simulation of organic and inorganic carbon cycling following carbon dioxide sorption onto soil amendments in drylands. Frontiers in Climate, 7, 1505472.
Synopsis: Terrestrial nature-based climate solutions (NbCS) face challenges in drylands due to arid conditions, yet these regions cover 45% of global land. Biochar, with high CO2 sorption capacity, may enhance carbon removal and soil health without disrupting large inorganic carbon pools. A 1D reactive transport model examines soil CO2 dynamics, showing how sorption influences dissolved inorganic carbon, pH, and calcite. Findings highlight the importance of response times and gas dynamics in dryland CDR strategies.
Mycorrhiza increases plant diversity and soil carbon storage in grasslands
Zhang, E., Wang, Y., Crowther, T. W., Sun, W., Chen, S., Zhou, D., ... & Yu, G. (2025). Mycorrhiza increases plant diversity and soil carbon storage in grasslands. Proceedings of the National Academy of Sciences, 122(7), e2412556122.
Synopsis: A study of 2296 field sites across China's grasslands shows that arbuscular mycorrhizal (AM) fungi enhance soil organic carbon (SOC) storage by increasing plant diversity and boosting belowground biomass. SOC levels are higher in ecosystems dominated by obligate and facultative mycorrhizal plants than in nonmycorrhizal systems. As temperature and precipitation rise, obligate mycorrhizal plants become more dominant. These insights highlight AM fungi's role in SOC storage under global change.
Optimal regulation of modified biochar in solid waste-derived lightweight aggregates: Enhancing carbonation mechanisms and negative carbon emissions
Yan, B., Hu, Y., Huan, Q., Liu, Z., Lai, J., Wang, S., & Song, M. (2025). Optimal regulation of modified biochar in solid waste-derived lightweight aggregates: Enhancing carbonation mechanisms and negative carbon emissions. Chemical Engineering Journal, 160920.
Synopsis: A novel cold-bonded artificial lightweight aggregate (CALA) was developed using modified biochar and multi-source solid waste, achieving high CO2 sequestration and a negative carbon footprint. Adding 3 wt% acid-modified biochar reduced porosity by 64.8%, increased compressive strength by 60.1%, and boosted CO2 absorption to 14.56 wt%. The optimized pore structure enhanced carbonation reactions, leading to improved mechanical properties and sustainability. This approach offers a dual benefit of CO2 capture and emissions reduction.
Integrating the physical harvesting of dead wood into fuel treatments to reduce wildfire hazards and enhance carbon benefits
Parajuli, R., Paudel, A., & Markwith, S. H. (2025). Integrating the physical harvesting of dead wood into fuel treatments to reduce wildfire hazards and enhance carbon benefits. Journal of Environmental Management, 376, 124535.
Synopsis: Fire suppression, global warming, and drought have intensified severe wildfires in western U.S. forests. While thinning and prescribed burning (Rx burn) are common fuel treatments, their effectiveness is debated. This study evaluates physical harvesting—removing surface fuels without burning—as an alternative to reduce wildfire risk and enhance carbon sequestration. Simulations show that combining thinning and physical harvesting (ThPy) minimizes fire hazards, lowers emissions, and improves carbon storage, especially through biochar conversion. Integrating physical harvesting with current fuel treatments may offer a sustainable, carbon-beneficial approach to wildfire management.
Tree Diversity Increases Carbon Stocks and Fluxes Above—But Not Belowground in a Tropical Forest Experiment
Schnabel, F., Guillemot, J., Barry, K. E., Brunn, M., Cesarz, S., Eisenhauer, N., ... & Potvin, C. (2025). Tree Diversity Increases Carbon Stocks and Fluxes Above—But Not Belowground in a Tropical Forest Experiment. Global Change Biology, 31(2), e70089.
Synopsis: A 16-year study from the Sardinilla experiment in Panama shows that mixed-species forests sequester significantly more aboveground carbon than monocultures, with five-species mixtures achieving 57% higher tree C stocks. Despite this, soil organic carbon (SOC) declined across diversity levels, with no significant difference between mixed and monospecific forests. The findings highlight the benefits of tree diversity for aboveground C sequestration, reinforcing the value of mixed-species plantings in forest restoration efforts.

How Nori Created a Direct Air Capture + Storage Methodology: A Case Study—w/ Radhika Moolgavkar & Rick Berg | Reversing Climate Change
"How do registries create carbon removal methodologies? Who should be involved in the process, and to what degree? How does one balance all of the competing attributes and stakeholders?
Today's episode is a show in three parts:
First, Nori co-founder and host ofReversing Climate Changeintroduces the context for the main segment which was recorded the better part of a year before its airing. He explores whether or not the quasi-regulatory requirement for registries not to also be marketplaces leads to proprietary methodologies.
Secondly, as Nori has closed down since the recording of this episode, Ross chats with Anu Khan, the Founder and Executive Director of the Carbon Removal Standards Initiative to discuss her work of building an ark for carbon removal methodologies and how that work informs policy and the growth of carbon removal.
Thirdly, is the original body of the podcast where Ross speaks with Radhika Moolgavkar, formerly the VP of Supply & Methodology at Nori, and Rick Berg, formerly Nori’s Director of Methodology, about the development of Nori’s Direct Air Capture + Storage methodology.
They discuss the importance of open methodology development for transparency and trust, and ungating their work so that others can use it and adapt it under the right Creative Commons licensure.
The nuts and bolts of how the expert advisory panel and public comment period work, as well as how that feedback filters back into the methodology, is explained.
The podcast also covers the decision behind selecting DAC amongst all of the other CDR methodologies, the challenges in methodology harmonization across registries and geographies, and how to handle the future of methodological updates as the industry evolves and more is learned."
Will Trees Play a Role in the Future of Carbon Removal?—w/ Lisett Luik, Co-Founder of Arbonics | Reversing Climate Change

Brad and Tannis share insights from Cascade’s development of a data quarry method that could fill an important gap in existing carbon data quantification methods — and ultimately unlock greater scientific understanding of ERW."
CDR at DoE is dead - or is it? | The CDR Policy Scoop
"In February 2025, all probationary contract staff at the Department of Energy were terminated, including the most incredibly talented and experienced people who had turned the U.S. into a CDR powerhouse over the previous years.
What does this - alongside the freezing of IRA and BIL funds - mean for CDR in the U.S. moving forward? How will DAC Hubs be affected? What about the Public Procurement Purchase Prize?
To make sense of this very difficult and sensitive situation, Eve Tamme and Sebastian Manhart are joined by the one and only Noah Deich, who initiated and led many of the CDR initiatives the DoE became famous for."

Cities and Carbon Removal: Meet the Next Agents of Change | Institute for Responsible Carbon Removal
"Join the Institute for Responsible Carbon Removal for the next event in its webinar series, “Scrubbing the Skies: The Role of Carbon Dioxide Removal in Combating Climate Change.” The series focuses on scientific, technological, legal, political, and justice-focused issues associated with carbon dioxide removal, and is hosted by the Institute’s Co-Director Wil Burns.
Cities hold a vast untapped potential for carbon dioxide removal (CDR). Scientists estimate a potential to remove upwards of 1Gt CO2 annually in urban environments. Two new initiatives are breaking ground on tapping into this opportunity:
-City CDR Initiative: A research and capacity building program targeting municipal governments around the globe. The initiative aims to unlock the power of cities to catalyze CDR deployment, while maximizing synergies with social, economic and environmental urban priorities. A current project funded by Breakthrough Energy is baselining the urban removal methods, technical value chains, and policy strategies. Partners include C40 Cities, the Global Covenant of Mayors, XPRIZE, Carbon Gap, Carbon180, RMI, Global Carbon Removal Partnership, and Carbon Removal India Alliance.
-City CDR Purchasing Challenge: A community-driven initiative to mobilize local support for high-quality CDR purchases. It empowers residents to lead campaigns in their cities, raising funds to purchase vetted CDR credits while fostering local government engagement in combating climate change. The purchasing challenge aims to promote awareness and action on carbon removal at the community level, create a first proactive exploration of direct investment in carbon removal at the local government level, and foster partnerships among residents, organizations, and governments."

‘What is CDR?’ Is the Wrong Question—CarbonPlan Explains Why | Remove and Reflect Podcast
"Mr. Sun (AI character) and Ms. Remove (AI character) discuss a new CarbonPlan commentary that explores the complexities of defining carbon dioxide removal (CDR) and argues that the primary question shouldn't be 'What is CDR?' Instead, it suggests focusing on whether a CDR activity is part of a system that can achieve net-zero emissions, become net-negative, and be accurately quantified. The piece highlights challenges in distinguishing between CDR and avoided emissions, particularly regarding projects like corn ethanol retrofits. It argues that focusing solely on project-level impacts can be misleading and that a broader systems view is necessary. The authors propose four key questions to guide effective CDR investments, emphasizing innovation and long-term scalability. Ultimately, the commentary suggests that the goal is to ensure investments build towards effective CDR for a net-zero future.

Methane Removal via Enhanced Chlorine Sinks: A Sustainable Approach | Remove and Reflect Podcast
"In this episode, Mr. Sun and Ms. Remove dive into a new paper that explores the feasibility of using chlorine sinks to remove methane from the atmosphere as a climate change mitigation strategy. It proposes using electrolysis of brine to generate chlorine gas, which can then be photolyzed to create atomic chlorine to speed up methane oxidation. The study evaluates the integration of this technology with existing industrial chlor-alkali processes to potentially achieve negative greenhouse gas emissions. It discusses deployment methods for point sources and large-scale atmospheric remediation, addressing associated costs, potential risks, and required developments. The analysis suggests that this approach could be a cost-competitive and complementary strategy to direct air capture of carbon dioxide in limiting global warming. Furthermore, the document looks forward to further research needs, and mentions the need for safety and environmental assessments before implementing the methods proposed.
