RESEARCH PAPERS
Transforming US agriculture for carbon removal with enhanced weathering
Beerling, D. J., Kantzas, E. P., Lomas, M. R., Taylor, L. L., Zhang, S., Kanzaki, Y., ... & Val Martin, M. (2025). Transforming US agriculture for carbon removal with enhanced weathering. Nature, 1-10.
Synopsis: According to this study, enhanced weathering (EW) on U.S. farmlands could sequester 0.16–0.30 GtCO₂/year by 2050, rising to 0.25–0.49 GtCO₂/year by 2070. Geochemical assessments indicate long-term CDR potential, with added benefits of reducing ozone and aerosols. Costs are initially high but decline to $100–150/tCO₂ by mid-century. While not a substitute for emission reductions, EW is a promising tool for net-zero goals. Scaling an EW industry will require decades, alongside further study of public awareness and equity impacts.
How to govern carbon dioxide removal: an assessment framework for policy instruments
Holland-Cunz, A., & Baatz, C. (2025). How to govern carbon dioxide removal: an assessment framework for policy instruments. Climate Policy, 1-16.
Synopsis: Global climate governance requires Carbon Dioxide Removal to meet temperature targets, but voluntary corporate action is insufficient. Policy instruments—such as regulations, taxes, and subsidies—are crucial for incentivizing CDR. This paper presents a framework with 15 criteria across six dimensions to assess CDR policy feasibility and desirability. It aids policymakers and stakeholders in making transparent, well-justified decisions, fostering informed deliberation on effective CDR governance pathways.
Atmospheric CO2 Removal Efficiency through Enhanced Silicate Weathering in Croplands: A Review with Emphasis on the Contribution of Fungi
Li, Z. B., Li, G., Adams, J. M., Guan, D. X., Zhao, L., Bian, R., ... & Chen, J. (2025). Atmospheric CO2 Removal Efficiency through Enhanced Silicate Weathering in Croplands: A Review with Emphasis on the Contribution of Fungi. Journal of Earth Science, 36(1), 197-211.
Synopsis: Enhanced silicate weathering (ESW) is a geoengineering approach to carbon dioxide removal by accelerating silicate rock weathering. Field trials show CDR efficiencies comparable to or exceeding mesocosm experiments, especially with wollastonite. The role of fungi in enhancing weathering is highlighted, suggesting fungal introduction could boost ESW efficiency. However, key questions on fungal persistence, long-term CDR impact, and potential CO2 emissions must be addressed for sustainable implementation.
Biotechnology in direct air capture, enhanced weathering, and methane removal: emerging opportunities and gaps
Reginato, P. L. Biotechnology in direct air capture, enhanced weathering, and methane removal: emerging opportunities and gaps. Frontiers in Climate, 6, 1440833.
Synopsis: Biotechnology could play a pivotal yet underexplored role in scaling greenhouse gas removal (GHGR) to meet 2050 net emissions targets. Key opportunities include using carbonic anhydrase to enhance CO₂ capture in direct air capture, leveraging microbes to accelerate enhanced rock weathering, and deploying methanotrophic bacteria or enzymes for atmospheric methane removal. However, progress is hindered by knowledge gaps, limited interdisciplinary collaboration, and a lack of risk-tolerant funding. Addressing these challenges through clearer problem articulation and targeted research investment could accelerate innovation in biotechnological GHGR solutions.
Transitioning from emission source to sink: Economic and environmental trade-offs for CO2-enhanced coalbed methane recovery of Mannville coal Canada
Ma, H., Yang, Y., Xue, Z., Clarkson, C. R., & Chen, Z. (2025). Transitioning from emission source to sink: Economic and environmental trade-offs for CO2-enhanced coalbed methane recovery of Mannville coal Canada. Science of The Total Environment, 966, 178721.
Synopsis: CO₂-enhanced coalbed methane (CO₂-ECBM) recovery offers a dual benefit of energy production and geological carbon sequestration (GCS). Using Alberta’s Mannville coal as a case study, this study presents an engineering, economic, and environmental (3E) analysis. Findings show deep coal seams as viable CO₂ sinks, potential for carbon-neutral/negative CBM, and economic trade-offs requiring policy support. A $175/tCO₂ carbon tax and DAC cost reductions are needed to make CO₂-ECBM a viable CDR strategy.
Expert projections on the development and application of bioenergy with carbon capture and storage technologies
Heimann, T., Wähling, L. S., Honkomp, T., Delzeit, R., Pirrone, A., Schier, F., & Weimar, H. (2025). Expert projections on the development and application of bioenergy with carbon capture and storage technologies. Environmental Research Letters, 20(2), 024059.
Synopsis: Bioenergy with carbon capture and storage (BECCS) is key to IPCC emission pathways but faces uncertainties in cost and scalability. A global expert survey found BECCS most promising in Europe and North America, with strong potential in biofuels and thermal power. Costs range from $100–200/tCO₂, with capture potential of 50–200 MtCO₂/yr by 2030. Including Global South perspectives is crucial. Findings help refine interdisciplinary models assessing BECCS trade-offs and long-term sustainability.
The Role of Marine CO2 Removal in Combating Climate Change
Vican, S., Gavin, M., Burns, W., Edwards, D., & Webb, R. M. (2025). The Role of Marine CO2 Removal in Combating Climate Change. Env't L. Rep., 55, 10005.
Synopsis: Marine carbon dioxide removal is gaining attention for its potential role in combating climate change, but its governance remains fragmented. In U.S. waters, mCDR is regulated by a patchwork of laws, while international treaties lack clear guidelines for open-ocean deployment. A panel hosted by the Environmental Law Institute on September 30, 2024, discussed the challenges and opportunities of scaling mCDR. This transcript captures key insights from the discussion, edited for clarity and conciseness.
Do oversimplified durability metrics undervalue biochar carbon dioxide removal?
Ringsby, A. J., & Maher, K. (2025). Do oversimplified durability metrics undervalue biochar carbon dioxide removal?. Environmental Research Letters.
Synopsis: Biochar soil amendment is a viable carbon dioxide removal (CDR) strategy, but assessing its durability remains complex. Current methodologies rely on H/C ratio-based models, which may oversimplify project outcomes and undervalue biochar’s removal potential. Re-analysis of incubation data suggests biases toward certain feedstocks and exclusion of key environmental factors. To improve CDR crediting, the study recommends developing a comprehensive database, refining durability assessments, and integrating in-field measurement protocols.
Effects of forest age and stand density on the growth, soil moisture content, and soil carbon content of Populus simoni plantations in the sandy area of western Liaoning, Northeast China
Chen, H., Zhang, Z., Yang, X., Ai, X., Wang, Y., & Liu, P. (2025). Effects of forest age and stand density on the growth, soil moisture content, and soil carbon content of Populus simoni plantations in the sandy area of western Liaoning, Northeast China. Scientific Reports, 15(1), 2499.
Synopsis: Poplar plantations in western Liaoning play a vital role in wind protection, sand stabilization, and carbon sequestration. A study of 75 plots in Fuxin City revealed that tree growth dynamics and soil properties vary with stand density and age. Younger forests benefit from higher stand density, while mature plantations see reduced growth at high densities. Soil carbon content increases with age, peaking in surface layers. With a total soil carbon stock of ~3.0 million tons, optimizing stand density and forest age distribution is key to maximizing ecological and sequestration benefits.
Bargaining powers in cooperative Carbon Dioxide Removal deployment
Jagu, E., Chiquier, S., Lowing, D., Massol, O., & Mac Dowell, N. (2024). Bargaining powers in cooperative Carbon Dioxide Removal deployment. Climate Policy.
Synopsis: International cooperation can significantly lower Carbon Dioxide Removal costs, with reductions ranging from 11% to 43%, according to a study using cooperative game theory and the MONET framework. The analysis of US, EU, Brazil, and China highlights two key regional bargaining power types: (1) resource-rich but low historical emitters (e.g., Brazil) and (2) high-demand regions with limited domestic resources (e.g., US, China). These findings suggest that Global South nations with strong CDR potential could play a pivotal role in shaping equitable climate agreements under Article 6 of the Paris Agreement.
No-tillage practice enhances soil total carbon content in a sandy Cyperus esculentus L. field
Wang, C., Hu, Y., Wu, H., Wang, Z., Cai, J., Liu, H., ... & Li, H. (2025). No-tillage practice enhances soil total carbon content in a sandy Cyperus esculentus L. field. Ecological Processes, 14(1), 9.
Synopsis: No-tillage (NT) enhances soil carbon (C) sequestration in semi-arid sandy soils by increasing plant biomass, microbial C use efficiency, and stable soil organic carbon. Field experiments in China's Horqin sandy land showed NT outperformed conventional tillage (CT) in boosting total soil C. NT promoted oligotrophic bacterial dominance, reinforcing carbon stability. These findings improve understanding of NT’s role in soil health and inform sustainable tillage practices for both yield and C sequestration.
Half of land use carbon emissions in Southeast Asia can be mitigated through peat swamp forest and mangrove conservation and restoration
Sasmito, S. D., Taillardat, P., Adinugroho, W. C., Krisnawati, H., Novita, N., Fatoyinbo, L., ... & Lupascu, M. (2025). Half of land use carbon emissions in Southeast Asia can be mitigated through peat swamp forest and mangrove conservation and restoration. Nature Communications, 16(1), 740.
Synopsis: Peat swamp forests (PSFs) and mangroves in Southeast Asia contribute nearly half of the region’s land-use change emissions, yet they also present significant mitigation opportunities. Between 2001–2022, land-use changes in these ecosystems generated approximately 691.8 ± 97.2 TgCO₂e annually, with Indonesia, Malaysia, Myanmar, and Vietnam accounting for over 90% of emissions. However, conservation and restoration efforts could reduce emissions and sequester an additional 94.4 ± 7.4 TgCO₂e per year. Despite covering only 5.4% of SEA’s land area, these carbon-rich ecosystems are critical for climate mitigation, biodiversity, and local livelihoods.
Tidal-driven N2O emission is a stronger resister than CH4 to offset annual carbon sequestration in mangrove ecosystems
Fu, C., Shen, Z., Tang, S., Li, F., Quan, X., Wang, Y., ... & Tan, E. (2025). Tidal-driven N2O emission is a stronger resister than CH4 to offset annual carbon sequestration in mangrove ecosystems. Science of The Total Environment, 964, 178568.
Synopsis: Mangrove ecosystems play a dual role in climate mitigation by storing significant "blue carbon" while also emitting methane (CH₄) and nitrous oxide (N₂O), which can offset sequestration benefits. A study in Dongzhaigang Bay, China, found that CH₄ and N₂O emissions reduce the net carbon sequestration capacity of mangroves by 8.7%, with N₂O contributing the majority (7.4%). Tidal-driven processes, such as porewater outwelling and sediment resuspension, drive the lateral export of dissolved GHGs. These findings emphasize the need for comprehensive assessments of non-CO₂ GHG fluxes to accurately quantify mangrove carbon dynamics.
A Capabilities Approach to Carbon Dioxide Removal
Paiusco, E. (2025). A Capabilities Approach to Carbon Dioxide Removal. Ethics, Policy & Environment, 1-21.
Synopsis: The ethical debate around carbon dioxide removal has expanded to consider its role within broader climate mitigation efforts and sustainable development. This article examines the perspectives of Darrel Moellendorf, who advocates for CDR as a means to support poverty-alleviating sustainable development, and Henry Shue, who warns against overreliance on CDR at the expense of immediate emissions reductions. Moving beyond this debate, the article argues that a capabilities approach—focusing on human well-being—can provide a more comprehensive ethical framework for evaluating CDR's role in climate policy.
Biochar and Atmospheric Carbon Dioxide Removal
Burns, W. (2025). Biochar and Atmospheric Carbon Dioxide Removal. In The Palgrave Encyclopedia of Sustainable Resources and Ecosystem Resilience (pp. 1-11). Cham: Springer Nature Switzerland.
Synopsis: This chapter examines biochar as a carbon dioxide removal strategy, highlighting its technological readiness and potential contributions to climate mitigation. Biochar, produced through the pyrolysis of biomass, offers durable carbon sequestration while providing co-benefits such as soil fertility enhancement and improved water retention. The chapter explores biochar production methods, its role in meeting carbon removal targets, potential risks, and pathways for large-scale adoption.

Experimental Optimization for Macrocystis Pyrifera Degradation at Different Temperature Regimes to Inform Carbon Dioxide Removal Strategies
Matsumura, S. (2024). Experimental Optimization for Macrocystis Pyrifera Degradation at Different Temperature Regimes to Inform Carbon Dioxide Removal Strategies (Doctoral dissertation, UC Santa Barbara).
Synopsis: Upscaled carbon dioxide removal is needed to meet climate targets, with macroalgae sequestration being a potential strategy. This study examined the degradation rates of Macrocystis pyrifera under different temperatures and conditions. Results show intact kelp in colder waters degrades more slowly, enhancing sequestration potential, but increases dissolved organic carbon (DOC) release. Warmer waters accelerate degradation and inorganic carbon accumulation, highlighting key factors for optimizing ocean-based CDR strategies.
Harnessing seaweed farming for climate mitigation in South Korea: evaluating carbon dioxide removal potential and future research directions
Kim, K. Y. (2024). Harnessing seaweed farming for climate mitigation in South Korea: evaluating carbon dioxide removal potential and future research directions. Algae, 39(4).
Synopsis: Seaweed farming is a scalable carbon dioxide removal strategy with direct sequestration and indirect climate benefits. In South Korea, its advanced aquaculture infrastructure and coastal resources support expansion, though challenges remain, including ecological trade-offs and the need for robust monitoring. Scaling offshore farming, improving MRV systems, and enhancing product innovation can maximize climate impact. Addressing key research gaps will help position seaweed farming as a vital component of South Korea’s climate strategy.
Evaluating Enhanced Rock Weathering as a Tool for Soil GHG Reduction and Carbon Sequestration in Croplands
Geoghegan, E. K. (2024). Evaluating Enhanced Rock Weathering as a Tool for Soil GHG Reduction and Carbon Sequestration in Croplands (Doctoral dissertation, Cornell University).
Synopsis: Enhanced Rock Weathering is a promising carbon sequestration strategy, but field-scale research reveals mixed results. A multi-year study across diverse U.S. agricultural sites found that while ERW can alter soil alkalinity, its effects on greenhouse gas emissions (CO₂, CH₄, N₂O) were inconsistent. Site-specific factors and organic amendments influenced outcomes, underscoring the need for further research to optimize ERW for climate mitigation in agriculture.

PODCASTS
Like-For-Like - the policy silver bullet? | The CDR Policy Scoop
"In carbon removal policy circles, three simple words - like-for-like - seem to come up more and more. It is a simple and obvious concept that is actually incredibly complex and misunderstood.
Robert Höglund joins Eve Tamme and Sebastian Manhart in exploring like-for-like as a concept, why it is becoming a core pillar of CDR policy design and what net-zero targets should actually look like."
What's the deal with enhanced rock weathering to store CO2? | Volts
"In this episode, I talk with climate scientist Zeke Hausfather about how enhanced rock weathering (ERW) turbocharges a natural process to permanently store CO₂. We dig into how it profits from existing infrastructure, and the big questions around measuring and verifying the carbon captured. Zeke also explains why farmers might actually benefit from spreading all those rocks — and why ERW could become a key, if limited, piece of the broader climate puzzle."
What we learned from the world's largest EW greenhouse experiment | Carbon Drawdown Initiative
"When we set out to run the world’s largest greenhouse Enhanced Weathering (EW) experiment, we expected to measure carbon dioxide removal (CDR) by tracking alkalinity in soil leachate. What we didn’t expect was to uncover a “cation-eating monster soil” that trapped essential weathering products—or a “procrastinating basalt” that refused to release cations quickly enough. These surprises, along with thousands of chemical and physical soil measurements, forced us to rethink how one can effectively assess CDR through EW - How do we do MRV for EW properly?"
Marine Carbon Dioxide Removal: The Newest Climate Mitigation Technique | NOC Into the Blue Podcast
"The ocean acts as the planet's largest carbon reservoir and it's fundamentally important in regulating climate systems and atmospheric carbon dioxide. Dr Chris Pearce joins Dr Zoe Jacobs to learn more about the process, implementation and importance of marine carbon dioxide removal and how it's vital in the ongoing protection of our oceans, including some exciting projects currently underway."
