RESEARCH PAPERS
Wolf reintroduction to Scotland could support substantial native woodland expansion and associated carbon sequestration
Spracklen, D. V., Chapman, P. J., Fletcher, T., Lane, J. V., Nilsen, E. B., Perks, M., ... & Scott, C. E. (2025). Wolf reintroduction to Scotland could support substantial native woodland expansion and associated carbon sequestration. Ecological Solutions and Evidence, 6(1), e70016.
Synopsis: This study suggested that reintroducing grey wolves to the Scottish Highlands could help control red deer populations, reducing browsing pressure and enabling natural woodland regeneration. This expansion of native woodlands could sequester around 1.0 Mt CO₂ annually, with each wolf contributing 6,080 t CO₂ per year. Beyond climate benefits, wolf-driven ecosystem restoration could offer economic opportunities through carbon finance.
Economic feasibility of biochar for carbon stock enhancement in Finnish agricultural soils
Jokubė, M., Hyyrynen, M., Pihlainen, S., & Hyytiäinen, K. (2025). Economic feasibility of biochar for carbon stock enhancement in Finnish agricultural soils. Carbon Management, 16(1), 2465328.
Synopsis: Biochar can sequester atmospheric CO₂ in soil for years, offering climate benefits. This study assesses its economic feasibility for Finnish agricultural soils under warming conditions. Monte Carlo simulations show that at the EU ETS carbon price (€88/t CO₂eq), biochar costs must drop to one-third of current levels or subsidies must increase 2–9 times. Alternatively, feasibility is possible with doubled carbon prices and halved biochar costs. A more developed biochar market is needed for competitiveness.
Direct effects of ocean alkalinity enhancement in the Baltic Sea -results from in-silico experiments
Anschütz, A. A., Marquez Lencina Avila, J., Rehder, G., Cahill, B., Neumann, T., & Radtke, H. Direct effects of ocean alkalinity enhancement in the Baltic Sea-results from in-silico experiments. Frontiers in Climate, 7, 1450468.
Synopsis: Ocean alkalinity enhancement (OAE) using calcite is being explored for carbon dioxide removal in the Baltic Sea, where undersaturation at shallow depths may enhance dissolution. This study simulates calcite release near sediments, showing that enhanced solubility significantly boosts dissolution rates in coastal sites but not in deep basins. Results highlight site-specific CO₂ uptake potential and environmental considerations, emphasizing the need for further research on dissolution rates and ecological impacts.
Thermal Ca2+/Mg2+ exchange reactions to synthesize CO2 removal materials
Chen, Y., & Kanan, M. W. (2025). Thermal Ca2+/Mg2+ exchange reactions to synthesize CO2 removal materials. Nature, 1-8.
Synopsis: Mg-rich silicate minerals offer a vast potential for carbon dioxide removal, but their slow reaction rates limit practical use. This study demonstrates that reacting CaCO₃ and CaSO₄ with Mg-rich silicates accelerates carbonation, forming Ca₂SiO₄ and MgO, which rapidly absorb CO₂ under ambient conditions. This process, requiring less than 1 MWh per tonne of CO₂ removed, is about twice as efficient as leading direct air capture methods, unlocking Mg-rich silicates for large-scale, permanent CDR.
Applicability of Adsorbents in Direct Air Capture (DAC): Recent Progress and Future Perspectives
Chuah, C. Y., Ho, Y. L., Syed, A. M. H., Thivyalakshmi, K. G. K., Yang, E., Johari, K., ... & Poon, W. C. (2025). Applicability of Adsorbents in Direct Air Capture (DAC): Recent Progress and Future Perspectives. Industrial & Engineering Chemistry Research.
Synopsis: Carbon capture, utilization, and storage (CCUS) helps mitigate CO₂ emissions, but over 50% of global emissions come from distributed sources, requiring negative emission technologies (NETs). Direct air capture (DAC) using solid sorbents is a promising approach due to lower energy use and high CO₂/N₂ selectivity. Amine-appended adsorbents show strong CO₂ affinity at low pressure. This review explores DAC sorbent performance, emphasizing adsorption/desorption cycling and future feasibility.
Tropospheric methane remediation by enhancing chlorine sinks
Yuan, Q., Xiao, B., de Richter, R., Li, W., Quesada-Cabrera, R., & Ming, T. (2025). Tropospheric methane remediation by enhancing chlorine sinks. RSC Sustainability.
Synopsis: The Paris Agreement aims for net-zero GHG emissions by 2050, but methane remains a major challenge despite the Global Methane Pledge’s 30% reduction goal by 2030. Studies suggest methane emissions will continue rising, necessitating removal technologies. This work explores enhancing the chlorine atom sink to accelerate methane oxidation, integrating it with industrial chlor-alkali processes. Feasibility, costs, risks, and potential benefits for atmospheric methane remediation by 2050 are assessed.
Terrestrial Storage of Biomass (Biomass Burial): A Natural, Carbon-Efficient, and Low-Cost Method for Removing CO2 from Air
Amelse, J. (2024). Terrestrial Storage of Biomass (Biomass Burial): A natural, carbon-efficient, and low-cost method for removing CO2 from air. Carbon-efficient, and Low-cost Method for Removing CO2 From Air (January 27, 2024).
Synopsis: Terrestrial Storage of Biomass (TSB) is a cost-effective Negative Emission Technology (NET) that sequesters CO₂ by burying biomass in pits designed to minimize decomposition. Unlike concerns about methane emissions, modeling shows that methane formation from buried biomass is slow, while atmospheric removal is rapid, preventing significant accumulation. TSB offers a natural, scalable carbon removal method, with growing recognition through carbon credits and recent US DOE funding for development.
Optimizing afforestation pathways through economic cost mitigates China’s financial challenge of carbon neutrality
Zhang, X., Fleskens, L., Zhang, N., Zhang, L., & Huang, Y. (2025). Optimizing afforestation pathways through economic cost mitigates China’s financial challenge of carbon neutrality. Communications Earth & Environment, 6(1), 119.
Synopsis: Afforestation plays a crucial role in China's carbon neutrality strategy, complementing emissions reductions. This study assesses cost-optimal afforestation pathways up to 2060, integrating spatial decomposition and dynamic modeling. Findings suggest afforestation's role should expand over time, while emissions reduction efforts gradually decrease. Coordinating afforestation with emissions cuts can optimize costs and mitigate financial risks, with spatiotemporal targeting of afforestation further enhancing economic efficiency.
Warming-induced retreat of West Antarctic glaciers weakened carbon sequestration ability but increased mercury enrichment
Zhou, C., Liu, M., Mason, R. P., Assavapanuvat, P., Zhang, N. H., Bianchi, T. S., ... & Raymond, P. A. (2025). Warming-induced retreat of West Antarctic glaciers weakened carbon sequestration ability but increased mercury enrichment. Nature Communications, 16(1), 1831.
Synopsis: The Southern Ocean is a key sink for atmospheric carbon and mercury, but climate warming may disrupt these processes. This study analyzes 20 sediment cores from the Ross Sea, showing stable organic carbon (OC) burial over 12,000 years, while mercury burial increased significantly. Warming has boosted glacial and terrestrial OC inputs, but greater remineralization offshore accelerates OC degradation into CO₂. This feedback loop could amplify mercury accumulation and CO₂ release, impacting marine ecosystems.
Impacts of land use change on carbon storage in the Guangxi Beibu Gulf Economic Zone based on the PLUS-InVEST model
Jiang, H., Cui, Z., Fan, T. et al. (2025). Impacts of land use change on carbon storage in the Guangxi Beibu Gulf Economic Zone based on the PLUS-InVEST model. Sci Rep 15, 6468.
Synopsis: This study examines land-use changes and carbon stock dynamics in Guangxi’s Beibu Gulf Economic Zone under China's dual-carbon goal. From 1980 to 2020, construction land expanded at the expense of other land types, reducing carbon storage. Forests hold the most carbon, followed by cultivated land. By 2030, only the ecological protection scenario increases carbon storage, reaching 12.69 × 10⁸ t. Urban and coastal areas show the lowest carbon storage, highlighting spatial disparities in carbon distribution.
Greenhouse gas removal in agricultural peatland via raised water levels and soil amendment
Jeewani, P. H., Brown, R. W., Rhymes, J. M., McNamara, N. P., Chadwick, D. R., Jones, D. L., & Evans, C. D. (2025). Greenhouse gas removal in agricultural peatland via raised water levels and soil amendment. Biochar, 7(1), 1-15.
Synopsis: Peatland drainage for agriculture turns carbon stores into major GHG emitters. This study explores strategies for net greenhouse gas removal (GGR) using organic amendments, water table management, and electron acceptors. Biochar showed the strongest carbon gain, reducing peat decomposition and CH₄ emissions, especially when combined with FeSO₄. Other amendments had weaker effects due to higher decomposition. Results suggest biochar addition to re-wetted peatlands could be a viable climate mitigation strategy.
Contrasting CO2 Dynamics in Seagrass Meadows Between Organic Carbon (OC)‐Rich Reef and OC‐Poor Terrestrial Sediments: Implications for Enhanced Alkalinity Production
Chou, W. C., Fan, L. F., Natividad, M. B., Chen, J. J., Tang, Z. W., Chen, H. F., ... & Hung, C. C. (2025). Contrasting CO2 dynamics in seagrass meadows between organic carbon (OC)‐rich reef and OC‐poor terrestrial sediments: Implications for enhanced alkalinity production. Geophysical Research Letters, 52(4), e2024GL112373.
Synopsis: Seagrass meadows play a crucial role in carbon dioxide removal through alkalinity-driven processes, with their impact varying by sediment type. This study finds that OC-rich reef sediments generate benthic alkalinity fluxes nearly two orders of magnitude higher than OC-poor terrestrial sediments, significantly enhancing CO₂ uptake. Seagrass meadows in high-OC reef sediments act as alkalinity hotspots, highlighting their potential to amplify the effectiveness of seagrass restoration for climate mitigation.
Mismatch Between Global Importance of Peatlands and the Extent of Their Protection
Austin, K. G., Elsen, P. R., Coronado, E. N. H., DeGemmis, A., Gallego‐Sala, A. V., Harris, L., ... & Zarin, D. (2025). Mismatch Between Global Importance of Peatlands and the Extent of Their Protection. Conservation Letters, 18(1), e13080.
Synopsis: This study revealed that peatlands store more carbon than all forest biomass combined, yet only 17% are protected globally, putting climate and biodiversity goals at risk. Boreal peatlands have just 11% protection, while temperate and tropical peatlands fare slightly better at 27%. Indigenous lands cover about a quarter of peatlands, offering lower human pressure, but nearly half of protected temperate and tropical peatlands still face threats. Global climate and biodiversity policies could drive greater conservation efforts and Indigenous stewardship support.
Blue carbon potential from rehabilitating urban mangrove forests in coastal city
Austin, K. G., Elsen, P. R., Coronado, E. N. H., DeGemmis, A., Gallego‐Sala, A. V., Harris, L., ... & Zarin, D. (2025). Mismatch Between Global Importance of Peatlands and the Extent of Their Protection. Conservation Letters, 18(1), e13080.
Synopsis: Mangrove forests are vital for blue carbon storage and climate mitigation, yet their carbon dioxide removal potential is often underassessed. A study in Xiamen, China, quantifies mangrove carbon stocks and restoration impacts, estimating an increase from 89.27 MgC ha⁻¹ in 2022 to 173.26 MgC ha⁻¹ by 2060. Findings underscore mangrove restoration’s role in carbon neutrality and highlight the need to account for non-CO₂ greenhouse gases in carbon budgeting.
The Role of Graphene in Bioenergy with Carbon Capture and Storage
Oluremi, D. (2025). The Role of Graphene in Bioenergy with Carbon Capture and Storage.
Synopsis: Graphene’s exceptional properties could revolutionize Bioenergy with Carbon Capture and Storage (BECCS) by enhancing biomass conversion, CO₂ separation, and carbon capture efficiency. Its superior adsorption capacity and stability improve bioenergy production while reducing costs and energy penalties. Scaling up graphene applications could boost BECCS feasibility, making it a more viable negative emissions technology.

Nuclear Explosions for Carbon Sequestration | Remove and Reflect Podcast
"In this episode, Mr. Sun (AI character) and Ms. Remove (AI character) discuss a recent paper by Andy Haverly proposing the use of a buried nuclear explosion in a remote seabed to pulverize basalt. The goal is to accelerate carbon sequestration through Enhanced Rock Weathering (ERW). Calculations suggest an 81-gigaton yield would be required to sequester 30 years of global carbon emissions. The proposal outlines logistical considerations for detonating the device deep underwater to contain the explosion and radiation. Analysis evaluates the safety, environmental impact, political feasibility, and financial viability of this radical approach compared to the impacts of ongoing climate change. The study ultimately concludes that this method could potentially be a viable and effective solution for addressing climate change.

Then the farmer makes several more passes spreading other material in different combinations: bone-white limestone dust, rich black biochar and chicken litter compost that reeks of ammonia. Each of these materials can boost both crop yields and the amount of carbon stored in soil. And Wilbourne Farm will help reveal whether these different ways of removing carbon from the atmosphere can be even more more effective in combination."
CDR.fyi: 2024 Carbon Dioxide Removal (CDR) Year in Review | Remove and Reflect Podcast
"In this episode, Mr. Sun (AI character) & Ms. Remove (AI character) discuss CDR.fyi's 2024 Year in Review, analyzing the durable carbon dioxide removal (CDR) market—its growth, challenges, and key trends. The market grew significantly in purchased volume, largely driven by repeat purchases from a concentrated number of North American tech companies buying from European suppliers. Investment in durable CDR saw a decline compared to the previous year, while the number of suppliers increased, creating potential consolidation if demand doesn't expand. The report points out concerns regarding a decline in first-time buyers and a need for cost reduction among suppliers. Furthermore, it explores pricing, deliveries, and leaderboards of purchasers and suppliers, and the geographical distribution of activity. The review emphasizes the need for more diverse buyers, supportive policies, and innovation to ensure the long-term success of the durable CDR sector.
