RESEARCH PAPERS
Leveraging ecosystems responses to enhanced rock weathering in mitigation scenarios
Gaucher, Y., Tanaka, K., Johansson, D. J., Goll, D. S., & Ciais, P. (2025). Leveraging ecosystems responses to enhanced rock weathering in mitigation scenarios. Nature Communications, 16(1), 3021.
Synopsis: This study evaluates EW's role in cost-effective mitigation pathways, considering both geochemical CDR from basalt weathering and biotic CDR from ecosystem growth. Using an integrated model, the research shows basalt application to forests could triple carbon sequestration compared to croplands, reducing reliance on BECCS and mitigating costs. Further field testing is needed to improve understanding.
Degradation-Resistant biochar Improves soil organic carbon Storage: Promoting autotrophic metabolism & increasing refractory organic carbon
Tang, H., Hu, J., Li, B., Liu, Y., Tong, W. K., Yue, M. R., ... & Li, J. (2025). Degradation-Resistant biochar Improves soil organic carbon Storage: Promoting autotrophic metabolism & increasing refractory organic carbon. Bioresource Technology, 132452.
Synopsis: This study investigates biochar prepared from cellulase-treated lignocellulose (BC-SR) as a soil amendment for enhancing carbon sequestration. BC-SR increased soil carbon by 4.39 mg C/g (16.10 mg CO2/g), 28% higher than ordinary biochar. BC-SR promoted microbial autotrophic metabolism, protected organic carbon by forming soil macroaggregates, and increased refractory organic matter. These effects resulted in more persistent carbon storage, demonstrating BC-SR's superior performance over conventional biochar in enhancing soil carbon fixation.
Ocean alkalinity destruction by anthropogenic seafloor disturbances generates a hidden CO2 emission
van de Velde, S. J., Hylén, A., & Meysman, F. J. (2025). Ocean alkalinity destruction by anthropogenic seafloor disturbances generates a hidden CO2 emission. Science Advances, 11(13), eadp9112.
Synopsis: The seafloor contributes 40% of the ocean’s alkalinity input, enhancing its ability to sequester CO2. This stud finds that, disturbances from mobile bottom-contact fishing and dredging disrupt this natural carbon sink, reducing alkalinity generation by 60 to 220 gigaequivalent year−1, equivalent to a CO2 reduction of 2 to 8 teragrams per year. This alkalinity destruction causes hidden CO2 emissions, underscoring the need for carbon accounting to account for both organic and inorganic carbon cycles in marine systems.
Removing atmospheric CO2 through mass scaleup of crops with enhanced root systems
Faggiani Dias, D., Hanna, R., Sachnik, J., Xu, Y., Gilbert, J., Busch, W., & Victor, D. G. (2025). Removing atmospheric CO2 through mass scaleup of crops with enhanced root systems. Environmental Research Letters.
Synopsis: The IPCC estimates that 5–16 GtCO2 must be removed annually to achieve global net-zero emissions. This study introduces a new model for assessing the scalability of CDR strategies, using genetically enhanced crops that increase soil carbon through larger root systems as an example. Enhanced crops could remove 0.9–1.2 GtCO2 per year within 13 years of deployment, seven times the current global voluntary offset market. Scalability depends on policy, and early scaling could help meet IPCC targets, despite the less permanent nature of soil carbon storage.
Global distribution, quantification and valuation of the biological carbon pump
Berzaghi, F., Pinti, J., Aumont, O., Maury, O., Cosimano, T., & Wisz, M. S. (2025). Global distribution, quantification and valuation of the biological carbon pump. Nature Climate Change, 1-8.
Synopsis: The biological carbon pump (BCP) sequesters significant amounts of carbon in the ocean, but its value for conservation, climate finance, and policy has been underappreciated. This study estimates that the BCP adds 2.81 GtC annually to the ocean, with a storage time of at least 50 years. Valued at US$545 billion per year in areas beyond national jurisdiction, and US$383 billion within exclusive economic zones, the BCP's total discounted value for 2023–2030 is US$2.2 trillion. These findings highlight the BCP's climate and economic significance.

Ferella, F., Suichies, A., Abdelkader, B. A., Dabhi, N. K., Werber, J., & de Lannoy, C. F. (2025). Ocean Alkalinity Enhancement Using Bipolar Membrane Electrodialysis: Technical Analysis and Cost Breakdown of a Full-Scale Plant. Industrial & Engineering Chemistry Research.
Synopsis: A techno-economic analysis of a bipolar membrane electrodialysis (BMED) plant for ocean alkalinity enhancement (OAE) was conducted, focusing on the production of alkaline solutions from desalination brine. The plant was designed to produce 47,200 t/year of NaOH solution and 46,600 t/year of HCl solution as a byproduct. Three valorization scenarios for HCl were explored. The levelized cost of CO2 sequestration ranged from 848 to 1076 USD/t CO2, with costs potentially dropping to 394 USD/t CO2 with improvements.
Life Cycle Assessment in the Monitoring, Reporting, and Verification of Land-Based Carbon Dioxide Removal: Gaps and Opportunities
Yao, Y., & Zhang, B. (2025). Life Cycle Assessment in the Monitoring, Reporting, and Verification of Land-Based Carbon Dioxide Removal: Gaps and Opportunities. Environmental Science & Technology.
Synopsis: This perspective examines life cycle assessment (LCA) studies and monitoring, reporting, and verification (MRV) protocols for land-based CDR methods. It compares carbon accounting and environmental impact methods for bioenergy with carbon capture, biochar, enhanced rock weathering, and afforestation. The analysis highlights LCA's role in supporting MRV by addressing baselines, uncertainty, and carbon pools. Recommendations include prioritizing timing, permanence, and dynamic modeling, with stronger LCA-CDR collaboration for effective carbon markets and policy.
Enhanced Basalt Weathering for CO2 Sequestration: Phase Dissolution Rates, Carbon Sequestration Mechanisms and Practical Application
Tang, X., Liu, H., & Liao, L. (2025). Enhanced Basalt Weathering for CO2 Sequestration: Phase Dissolution Rates, Carbon Sequestration Mechanisms and Practical Application. Environmental Research, 121492.
Synopsis: Enhanced basalt weathering is a promising method for CO2 reduction, but challenges in isolating basalt phases from soil hinder accurate dissolution rate measurements. This study combines magnetic separation and XRD-Rietveld fitting to quantify dissolution rates of various basalt phases, with a carbon sequestration rate of 9.728 t ha-1 a-1. It identifies early-stage decomposition of certain phases and the formation of secondary products like carbonates, zeolite, and serpentine. A feasibility assessment for China emphasizes key considerations for successful implementation in climate change mitigation.
Evolution of silicate weathering in the Yangtze River Basin since 3.5 Ma as archived in the East China Seas: Controlling factors and global significance
Zhang, J., Wan, S., Clift, P. D., Jin, H., Song, Z., Tang, Y., ... & Li, A. (2025). Evolution of silicate weathering in the Yangtze River Basin since 3.5 Ma as archived in the East China Seas: Controlling factors and global significance. Global and Planetary Change, 104807.
Synopsis: Silicate weathering is a crucial carbon sink over geological timescales, but its role in climate regulation—whether as a positive driver or negative feedback to climate change—remains unclear due to a lack of reliable flux estimates. This study reconstructs silicate weathering intensity and flux in the Yangtze River Basin over the past 3.5 million years, revealing a decreasing weathering intensity linked to global cooling. Silicate weathering flux is primarily controlled by erosion flux, with climate change and tectonic activity influencing CO2 consumption and global cooling.
Dynamic Accounting of Carbon Uptake in the Built Environment
Van Roijen, E., Kane, S., Fan, J., Olsson, J. A., Bose, B., Hendrickson, T. P., ... & Miller, S. A. (2025). Dynamic Accounting of Carbon Uptake in the Built Environment. Environmental Science & Technology.
Synopsis: This study introduces a framework for analyzing cradle-to-grave CO2e balance in building materials, using a time-dependent global warming potential calculation. Applying the D-CUBE tool to concrete and cross-laminated timber (CLT), it finds CLT's long carbon storage reduces warming, while concrete's slow carbonation uptake has limited effect. D-CUBE allows consistent comparisons of materials and mitigation strategies, helping identify pathways to net-carbon-sequestering building materials across life-cycle stages.
Potential conflicts between fishing and oceanic carbon sequestration in 15% of the ocean
Mariani, G., Guiet, J., Bianchi, D., DeVries, T., Durfort, A., Barrier, N., ... & Mouillot, D. (2025). Potential conflicts between fishing and oceanic carbon sequestration in 15% of the ocean. One Earth.
Synopsis: The ocean offers both socioeconomic and climate benefits, but fishing activities can disrupt carbon sequestration by marine macrofauna and sediments. Understanding the spatial overlap between fishing and key carbon sequestration areas is crucial for effective fisheries management. This study identifies conflicting oceanic carbon areas for pelagic (COCA-P) and bottom-trawling fisheries (COCA-BT), revealing minimal overlap (1%) and suggesting targeted fishing adjustments could mitigate conflicts, balancing food security, economic interests, and carbon sequestration.
Comparative analysis of industrialization potentials of direct air capture technologies
Koch, R., & Dittmeyer, R. Comparative analysis of industrialization potentials of direct air capture technologies. Frontiers in Climate, 7, 1558396.
Synopsis: This study examines direct air capture technologies with the highest potential for achieving gigaton-scale capture capacity, including Alkaline Gas Washing, Temperature Vacuum Swing Adsorption, Electro Swing Adsorption, and Accelerated Weathering Carbon Capture. Using a multi-criteria decision-making model, the study finds that Electro Swing Adsorption has the highest potential but requires further research on costs and adsorbent supply. Accelerated Weathering Carbon Capture follows, offering low energy demand and no fresh water needs. Temperature Vacuum Swing Adsorption shows promise due to cost reduction potential, while Alkaline Gas Washing, though lower in potential, could still be viable at a gigaton scale with improvements.
Microbial photosynthesis mitigates carbon loss from northern peatlands under warming
Hamard, S., Planchenault, S., Walcker, R., Sytiuk, A., Le Geay, M., Küttim, M., ... & Jassey, V. E. (2025). Microbial photosynthesis mitigates carbon loss from northern peatlands under warming. Nature Climate Change, 1-8.
Synopsis: A study on northern peatlands reveals that warming increases microbial photosynthesis, with a 3.4 mgC m−2 h−1 rise per 1°C increase. By 2100, this could lead to a gain of 51.1 Tg of carbon per year, offsetting ~14% of projected CO2 emissions in northern peatlands under the SSP 5-8.5 scenario. Enhanced microbial photosynthesis accelerates peatland CO2 uptake by stimulating nutrient mineralization, highlighting the role of photosynthetic microbes in mitigating emissions and supporting long-term carbon storage.
Refined weathering CO2 budget of the Tibetan Plateau strongly modulated by sulphide oxidation
Liu, W., Xu, Z., Sun, H., Zhao, M., Xu, Y., & Guo, Z. (2025). Refined weathering CO2 budget of the Tibetan Plateau strongly modulated by sulphide oxidation. Nature Communications, 16(1), 2741.
Synopsis: This study examines CO2 consumption and release processes in the Tibetan Plateau, focusing on the role of sulfuric acid (H2SO4) in weathering. The research finds that silicate weathering is typical, but carbonate weathering flux accounts for 2.09% of the global total, with 80% of H2SO4 from pyrite oxidation consumed by carbonate weathering. This process counteracts ~58% of the CO2 consumption from silicate weathering. The findings provide evidence that pyrite weathering in orogens acts as a negative feedback on atmospheric CO2 levels.
Investigating Cropland's Soil Carbon Sequestration Potential to Reduce Climate Change with the Cool Farm Tool
Das, S. K. (2025). Investigating Cropland's Soil Carbon Sequestration Potential to Reduce Climate Change with the Cool Farm Tool. Water, Air, & Soil Pollution, 236(4), 251.
Synopsis: Organic farming significantly increased the soil organic carbon (SOC) pool, with saprotrophic fungus dominance and a shift in bacterial life-history strategy from K- to R-strategy driving these changes. Among various cropping systems, rice-vegetable pea had the highest active carbon pools (11.14 Mg ha−1) and carbon management index (197.29), making it the most effective system for carbon sequestration in the Sikkim Himalaya. Soybean-buckwheat and rice-buckwheat ranked second and third. The study suggests promoting rice-vegetable pea cropping for effective land management in the region.

This insightful talk will help you discover who these investors are, what motivates them, and the crucial elements they seek in a successful biochar initiative. Other key topics include the themes of "better, faster, cheaper," specific factors investors consider when funding biochar projects, and inspiring tales of biochar initiatives that have attracted significant capital and made a real impact.As Tom Steyer wisely said, "Innovation blooms where imagination is nurtured," highlighting the importance of creativity and visionary thinking in driving progress."
Can Enhanced Rock Weathering Supercharge Regenerative Farming + Fix the Climate? Prof David Beerling | Nick Breeze ClimateGenn
"Carbon dioxide removal (CDR) is a controversial topic and yet it is also embedded within many national plans for carbon reduction. David Beerling is the leading researcher in this field of Enhanced Rock Weathering, and here he shares a wide range of insights about the potential for deployment, effectiveness and scaling to meet our global challenges.
Obviously no one is suggesting that this can replace carbon emissions reductions. The transition to renewables is the critical societal evolution of our times. Even this obvious statement sounds controversial at a time when powerful state-backed corporations are doubling down on fossil fuel production and profiteering. These are tough times for anyone who understands the science of climate change and rate of ecological destruction, as we see the rise of corruption and actions of psychopaths that have long-term impacts on all our lives. With Europe having no choice but to propose hundreds of billions of euros be invested in a new arms race for defence in human conflict, we collectively appear blind to the threat posed by mother nature, a far mightier enemy of our own creation."

Inside the Race to Remove CO2 from Our Ocean | Meet the Finalists | XPRIZE Carbon Removal | XPRIZE
"Does the ocean hold the key to reversing climate change? Dive into Episode 1 of the XPRIZE Carbon Removal docuseries as it examines groundbreaking innovations that are supercharging the ocean's capacity to remove and store atmospheric carbon dioxide.
Meet the teams leading this ocean carbon removal revolution:
Kelp Blue, a finalist team from the Netherlands, is harnessing the power of photosynthesis by cultivating vast kelp forests. These marine plants absorb CO2 and sequester it in the surrounding sediments and deep ocean. Their model aims to boost marine biodiversity while sequestering carbon.
Planetary, a Canadian finalist team, leverages ocean chemistry to increase seawater's alkalinity, enhancing its ability to absorb CO2 from the air. Their process neutralizes CO2, storing carbon safely in the ocean.
Ebb Carbon employs an electrochemical process, electrodialysis, to remove acid from the ocean, enhancing CO2 capture and converting it into bicarbonate. This U.S.-based finalist team is working to scale its solution by partnering with existing coastal infrastructure.Captura, another U.S.-based finalist team, utilizes direct ocean capture technology, extracting CO2 from ocean water via an electrodialysis process for sequestration or utilization. Their process uses only ocean water and renewable electricity."

Evaluating the Role of Wood Products as Carbon Offsets | Resources for the Future
"After trees are harvested, their carbon storage capacities continue through wood products, contributing to US carbon sinks alongside living forests. Strong markets for wood products can encourage reforestation and prolong the duration of carbon storage, but challenges to the viability of these markets and calculating carbon credits, especially in the face of increased wildfire intensity and frequency, remain. On Wednesday, March 26, Resources for the Future (RFF) hosted a webinar convening researchers and forest sector analysts. Together, these experts addressed critiques; examined the role of wood products in carbon accounting and offset markets; identified opportunities for crediting protocols; and clarified the role of wood products in reducing net emissions."
Keep Calm and Remove On: CDR.fyi's 2024 Year in Review | 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.
The durable carbon removal (CDR) market has experienced significant growth, with purchases increasing 78% in 2024 to nearly 8 million tonnes. However, this growth is tempered by a plateauing of unique purchasers and a decline in first-time buyers. Additionally, investment activity has decreased, raising concerns about the market's future expansion.
While proactive purchaser leaders drove the initial sales, the market now risks stalling unless a new wave of purchasers enters to scale the market. This webinar will explore these trends and discuss the critical role of purchaser engagement in unlocking the market's full potential."
