RESEARCH PAPERS
Fair carbon removal obligations under climate response uncertainty
Ganti, G., Pelz, S., Klönne, U., Gidden, M. J., Schleussner, C. F., & Nicholls, Z. (2025). Fair carbon removal obligations under climate response uncertainty. Climate Policy, 1-13.
Synopsis: Deploying Carbon Dioxide Removal is essential for meeting climate goals, yet Earth System uncertainty is often overlooked. This study estimates that an extra 323–787 Gt CO2 of CDR may be needed after net zero for a very likely chance of limiting warming to 1.5°C. Cutting residual emissions (CO2, CH4, N2O) reduces reliance on large-scale CDR. Equitable allocation suggests North America's removal responsibility could be halved with deeper emission cuts, highlighting the need for rapid action.
Targeted carbon dioxide removal measures are essential for the cost and energy transformation of the electricity sector by 2050
Afrane, S., Ampah, J. D., Adun, H., Chen, J. L., Zou, H., Mao, G., & Yang, P. (2025). Targeted carbon dioxide removal measures are essential for the cost and energy transformation of the electricity sector by 2050. Communications Earth & Environment, 6(1), 227.
Synopsis: Carbon dioxide removal can ease the power sector's transition, while electrification can lower CDR’s emissions. Using a multisector model, this study finds that high CDR pathways could consume up to 5% of electricity by 2050. Limited CDR may increase asset stranding costs by $165-225B in fossil-heavy nations and require 15% extra power sector mitigation. While high CDR can reduce disruption, it risks higher committed emissions, requiring careful planning to balance transformation and climate goals.
Recent gains in global terrestrial carbon stocks are mostly stored in nonliving pools
Bar-On, Y. M., Li, X., O’Sullivan, M., Wigneron, J. P., Sitch, S., Ciais, P., ... & Fischer, W. W. (2025). Recent gains in global terrestrial carbon stocks are mostly stored in nonliving pools. Science, 387(6740), 1291-1295.
Synopsis: Terrestrial carbon sequestration has offset ~30% of anthropogenic emissions, but its distribution across biomass, soil, and sediments remains uncertain. Analyzing global data from 1992–2019, researchers found that ~35 ± 14 GtC was stored on land, primarily as nonliving matter, while live biomass changed only slightly. This challenges global vegetation models, which emphasize live biomass. Human activities like damming, wood harvest, and landfills contribute significantly, highlighting overlooked but persistent carbon sinks.
Big Decisions from Small Experiments: Observational strategies for biomass-based marine carbon storage
Raven, M., Evans, N., Martinez, A. M., & Phillips, A. A. (2025). Big Decisions from Small Experiments: Observational strategies for biomass-based marine carbon storage. Environmental Research Letters.
Synopsis: Biomass-based CO2 removal with marine storage leverages photosynthesis to sequester carbon in long-lived ocean reservoirs. This study outlines five key phases of such projects—inputs, placement, short-term response, long-term response, and functional stability—each requiring targeted observations across spatial and temporal scales. Integrating diverse data into Earth System models is crucial for predicting impacts, guiding deployment, and ensuring regulatory compliance at climatically relevant scales.
Powering Direct Air Capture: Overview of Existing Concepts and the Overlooked Role of Concentrated Solar Thermal Technologies
Prats-Salvado, E., Monnerie, N., & Sattler, C. (2025). Powering Direct Air Capture: Overview of Existing Concepts and the Overlooked Role of Concentrated Solar Thermal Technologies. Current Sustainable/Renewable Energy Reports, 12(1), 1-7.
Synopsis: This review examines energy sources for DAC, highlighting scalable, low-carbon options. While nuclear and curtailable renewables show promise, concentrated solar thermal (CST) has been largely overlooked despite being a cost-effective source of dispatchable heat. Interest is also growing in power-to-heat and fully electric solutions. Addressing these energy challenges is crucial for the widespread deployment of DAC.
Riverine Photosynthesis Influences the Carbon Sequestration Potential of Enhanced Rock Weathering
Neumann, R. B., Kukla, T., Zhang, S., & Butman, D. E. Riverine Photosynthesis Influences the Carbon Sequestration Potential of Enhanced Rock Weathering. Frontiers in Climate, 7, 1582786.
Synopsis: As climate mitigation lags, reliance on CO2 removal grows, with enhanced rock weathering (ERW) gaining attention. ERW sequesters carbon by forming dissolved inorganic carbon (DIC) and alkalinity, which must reach the ocean for long-term storage. However, river transport losses, particularly from aquatic photosynthesis, impact efficacy. Photosynthesis can uptake 1%–30% of DIC, altering sequestration outcomes. Understanding these biological processes is crucial for accurately assessing ERW’s potential.
Machine learning-based identification of key biotic and abiotic drivers of mineral weathering rate in a complex enhanced weathering experiment—Preprint
Janssens, I., Servotte, T., Calogiuri, T., Mortier, S., Niron, H., Corbett, T., ... & Verdonck, T. (2025). Machine learning-based identification of key biotic and abiotic drivers of mineral weathering rate in a complex enhanced weathering experiment. Open Research Europe, 5, 71.
Synopsis: This study explores the key drivers of enhanced mineral weathering for carbon dioxide removal using an 8-week experiment testing 29 abiotic and biotic factors. Machine learning models identified steel slag addition and mixed mineral grain sizes as dominant CDR drivers, with earthworms and microbes also playing a role. The findings highlight the complex interactions in mineral weathering and the power of machine learning to optimize CDR processes.
Liability Considerations for Marine Carbon Dioxide Removal Projects in U.S. Waters
Silverman-Roati, K., Lockman, M., & Webb, R. M. (2025). Liability Considerations for Marine Carbon Dioxide Removal Projects in US Waters.
Synopsis: Marine carbon dioxide removal holds promise for carbon sequestration, but controlled ocean trials are needed to assess efficacy and impacts. Legal considerations will shape research and deployment, yet little focus has been given to potential liability for project proponents. This report examines statutory and tort liability under U.S. law, highlighting uncertainties. It also explores alternative environmental liability frameworks that could better balance risk and benefits for marine CDR projects.
Wastewater alkalinity enhancement for carbon emission reduction and marine CO2 removal
Li, M., Chen, Y., Doyle, R., Testa, J., Gagnon, A., Bott, C. B., & Cai, W. J. (2025). Wastewater alkalinity enhancement for carbon emission reduction and marine CO2 removal. Environmental Research Letters.
Synopsis: Wastewater alkalinity enhancement offers a promising pathway for Ocean Alkalinity Enhancement by leveraging wastewater treatment plants (WWTPs) to reduce CO2 emissions and enhance oceanic carbon uptake. Modeling shows that upstream alkalinity addition (UpAdd) significantly lowers WWTP emissions, while downstream addition (DnAdd) boosts oceanic CO2 uptake. UpAdd achieves 30% greater total CO2 removal, highlighting WWTPs' potential as a scalable tool for global carbon management.
Electrodeposition of Carbon-Trapping Minerals in Seawater for Variable Electrochemical Potentials and Carbon Dioxide Injections
Devi, N., Gong, X., Shoji, D., Wagner, A., Guerini, A., Zampini, D., ... & Rotta Loria, A. F. (2025). Electrodeposition of Carbon‐Trapping Minerals in Seawater for Variable Electrochemical Potentials and Carbon Dioxide Injections. Advanced Sustainable Systems, 2400943.
Synopsis: Electrochemical seawater splitting offers a dual solution for hydrogen production and CO2 sequestration, generating hydrogen at the cathode while precipitating valuable minerals like calcium carbonate and magnesium hydroxide. This study explores optimizing mineral yield and selectivity under varying conditions, revealing opportunities to repurpose these byproducts for construction and environmental applications. Findings highlight seawater electrolysis as a scalable tool for clean energy and carbon management.
Carbon cycling across ecosystem succession in a north temperate forest: Controls and management implications
Nave, L. E., Gough, C. M., Clay, C., Santos, F., Atkins, J. W., Benjamins‐Carey, S. E., ... & Tallant, J. M. (2025). Carbon cycling across ecosystem succession in a north temperate forest: Controls and management implications. Ecological Applications, 35(1), e70001.
Synopsis: This study synthesizes decades of data on carbon cycling in north temperate forests, examining how disturbances and ecosystem changes shape carbon dynamics over two centuries of succession. Findings reveal that both severe and partial disturbances influence soil nitrogen, fungal communities, and tree competition, affecting soil carbon stocks and emissions. Climate change increasingly overrides community composition effects on carbon uptake. The study highlights key ecological drivers and management implications.
Activation and Fixation of Atmospheric CO2 through a 1,2,3-Triazole-based Mesoionic Carbene-Borane Adduct
Neubrand, M., Stubbe, J., Rudolf, R., Walter, R. R., Nößler, M., & Sarkar, B. (2024). Activation and Fixation of Atmospheric CO2 through a 1, 2, 3‐Triazole‐based Mesoionic Carbene‐Borane Adduct. Chemistry–A European Journal, e202403942.
Synopsis: This study introduces a simple, transition metal-free triazolylidene-borane adduct that captures atmospheric CO2 and converts it to formate. Key reaction intermediates were identified using NMR, IR spectroscopy, and X-ray diffraction. Notably, the research demonstrates the first closed-cycle conversion of CO2 to formic acid with this compound, highlighting a promising approach for sustainable carbon utilization.
Grazing decreases carbon storage in the Qinghai-Tibet Plateau grasslands
Huang, X., Liu, X., Liao, L., Li, J., Luo, G., Li, B., ... & Wang, Z. (2025). Grazing decreases carbon storage in the Qinghai-Tibet Plateau grasslands. Communications Earth & Environment, 6(1), 198.
Synopsis: A study using advanced modeling assessed carbon storage and grazing impacts on Qinghai-Tibet Plateau grasslands from 1979 to 2018. Results show significant carbon loss due to grazing, with vegetation carbon declining by 21.63 Tg and soil organic carbon by 108.83 Tg in 2018. Grazing reduced carbon density across most grasslands, emphasizing the need for sustainable management to mitigate carbon loss and maintain ecosystem stability.
Revisiting the soil carbon saturation concept to inform a risk index in European agricultural soils
Breure, T. S., De Rosa, D., Panagos, P., Cotrufo, M. F., Jones, A., & Lugato, E. (2025). Revisiting the soil carbon saturation concept to inform a risk index in European agricultural soils. Nature Communications, 16(1), 2538.
Synopsis: This study analyzing soil organic carbon (SOC) fractions across EU and UK pedo-climatic zones found that effective mineral-associated organic carbon (MAOC) capacity, rather than a universal maximum, governs SOC storage. Researchers developed an SOC risk index combining SOC changes and MAOC capacity, identifying 43–83 Mha of high-risk agricultural soils, mainly in cool, humid regions. The index offers a tool for policymakers to enhance SOC stability and preservation.
A greening Earth has reversed the trend of decreasing carbonate weathering under a warming climate
Zeng, S., Liu, Z., Jiang, Y., Goldscheider, N., Yang, Y., Zhao, M., ... & Shi, L. (2025). A greening Earth has reversed the trend of decreasing carbonate weathering under a warming climate. Nature Communications, 16(1), 2583.
Synopsis: This study on global vegetation greening and mineral weathering found a strong positive correlation between vegetation growth and carbonate weathering intensity [HCO3−]. Between 1982 and 2018, vegetation-driven weathering increased WSatm-CO2 by 6.1% in Southwest China and 2.4% globally. Without vegetation, warming alone reduced weathering by 1.3%. Estimates suggest global vegetation restoration could enhance carbonate weathering by 43.8%, underscoring its role in carbon sequestration.

SBTi - Step Forward or Missed Opportunity for CDR? | The CDR Policy Scoop
"8,000 companies have emission reduction targets validated by the Science Based Targets initiative. Only around 50 of them have so far purchased durable carbon removal.
Imagine if all of them purchased CDR? The impact could be >50Mt of demand. Per year. Starting from 2030.
On March 18th, the SBTi released the draft net-zero standard 2.0 which marks a potential inflection point. Will it:
Drive companies to begin CDR purchases immediately?
Keep CDR voluntary until the 2040s?
Inadvertently push companies away from SBTi due to concerns about mandatory CDR costs?
To make sense of this wide spectrum of possibilities, the CDR Policy Scoop is delighted to have Robert Höglund back on the show. He has been a member of the external SBTi Technical Advisory Group and understands the process and its implications for CDR like no other."

This is CDR: Open Carbon Protocol - Collaborative CDR Protocol Development | OpenAir
"Accurate Monitoring, Reporting, and Verification (MRV) is one of the biggest challenges in scaling high-quality carbon removal. How can we ensure that carbon removal projects are verifiable, transparent, and tradable at scale? In this episode of This is CDR, we sit down with Thomas Annicq (CEO) and Rio Richardson (CPO) from Open Carbon Protocol (OCP) ( a project of Oneshot.earth) to explore how their open-source, decentralized infrastructure is solving key MRV bottlenecks and enabling a more effective carbon market.
OCP is building a universal, blockchain-based standard for real-time MRV data integration, allowing carbon removal projects to seamlessly verify and issue high-integrity credits."
Equitable Pathways for Post-Net-Zero CDR Obligations: Insights from IAM | 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.
Carbon dioxide removal (CDR) plays two critical roles in climate mitigation: first, compensating for residual emissions to achieve net-zero, and second, reducing atmospheric CO₂ concentrations in the post-net-zero period to bring global temperatures back to safer levels. While most countries have pledged to reach net-zero at different timelines, there remains no clear consensus on how to equitably share the burden of CDR beyond net-zero, particularly for reversing temperature overshoot.
This webinar argues that while the first role of CDR—offsetting residual emissions—can ideally be minimized through rapid sectoral decarbonization, the second role—achieving net-negative emissions—remains unavoidable. Removing excess CO₂ from the atmosphere is essential for long-term climate stability. Although post-net-zero may seem distant, expectations around CDR deployment for that period have immediate implications, influencing contemporary policy decisions and shaping long-term planning. In this session, we will explore these concepts and present findings from our recent study, which employs integrated assessment modeling to examine the role of various CDR methods—including direct air capture, bioenergy with carbon capture and storage, and enhanced weathering—for Canada under different national carbon budgets derived from burden-sharing principles. The projected CDR growth rates are compared to the historical adoption rates of technologies in Canada, and the insights gained from these comparisons will also be presented."
Global Climate Emotions and Support for Climate Intervention Technologies | Remove and Reflect Podcast
"In this episode, our hosts Mr. Sun (AI-character) & Ms. Remove (AI-character) deep dived into a new research article that investigates the relationship between climate emotions and public support for climate intervention technologies across 30 countries, surveying over 30,000 individuals. The study mapped global incidences of fear, hope, anger, sadness, and worry related to climate change, revealing differences based on a country's level of development, with advanced economies reporting weaker climate emotions. Furthermore, it analyzed how these emotions correlate with support for and perceptions of carbon dioxide removal (CDR) and solar radiation modification (SRM), finding hope and worry to be consistently positive predictors of support. Finally, the research explored whether reading about different climate intervention categories influenced reported climate emotions, noting that information on ecosystems-based CDR increased hope compared to SRM.

Bye Bye 1.5, What's Next? | Climate Emergency Forum
"Join us for a critical discussion on the state of global warming and the implications of surpassing the 1.5°C target. The panel delves into the urgent realities of climate change exploring how feedback loops, such as wetlands emitting more methane and the Arctic switching from a carbon sink to a source, are accelerating climate disruption beyond human control. The conversation highlights the need for immediate action to mitigate these effects and prevent catastrophic outcomes.
The experts emphasize that the world is not just at 1.5°C but committed to far exceed this threshold due to lag effects and weakening carbon sinks. Peter Carter stresses the importance of understanding that even with drastic emission cuts, the planet will continue to warm due to existing commitments. Paul Beckwith discusses the challenges of restoring natural carbon sinks and the potential for geoengineering as a means to cool the planet quickly. Both speakers underscore the critical need for a multifaceted approach, including emission reductions, CO2 removal, and climate intervention methods."
Novel Field Experiment on Alkalinity Enhancement in Intertidal Environments | Remove and Reflect Podcast
"This episode hosted by Mr. Sun (AI-character) and Ms. Remove (AI-character) discuss a new paper that conducted a novel field experiment in a Portuguese salt marsh to assess marine alkalinity enhancement as a natural climate solution for reducing atmospheric CO2. The study involved deploying different sizes of olivine and basalt in contained plots and monitoring water properties over six months, comparing them to a control site. Initial findings indicate that the addition of these minerals increased total alkalinity in the porewater, suggesting a potential for enhanced CO2 uptake. The paper details the experimental design, methodology, and preliminary results, highlighting the strengths and limitations of this in situ approach for evaluating and scaling up alkalinity enhancement strategies.
