RESEARCH PAPERS
Towards negative carbon footprint: carbon sequestration enabled manufacturing of coral-inspired tough structural composites
Deng, H., Du, H., Li, K., Zhang, Y., Lee, K. H., Zheng, B., & Wang, Q. (2025). Towards negative carbon footprint: carbon sequestration enabled manufacturing of coral-inspired tough structural composites. npj Advanced Manufacturing, 2(1), 1.
Synopsis: Inspired by coral biomineralization, this study develops a method to convert CO2 into calcium carbonate minerals using electrochemical manufacturing around 3D-printed polymer scaffolds. The resulting composites exhibit exceptional strength, fracture toughness, fire resistance, and repairability. Scalable and sustainable, this approach enables large-scale, load-bearing structures with a negative carbon footprint, offering a path to eco-friendly engineering solutions.
Enhanced CO2 removal and improved carbon budget by enhanced rock weathering: A field experiment in Hokkaido, Japan
Yang, Y., Kosaka, G., Uchibayashi, H., Zhu, Y., Kuramochi, K., Shinano, T., ... & Toma, Y. (2024). Enhanced CO2 removal and improved carbon budget by enhanced rock weathering: A field experiment in Hokkaido, Japan.
Synopsis: This study evaluated the short-term effects of enhanced rock weathering (ERW) with basalt powder on CO₂ emissions and carbon balance in a soybean field in Japan. Basalt application (143 t ha⁻¹) increased soil pH and reduced water content, achieving a CO₂ removal rate of 0.81 ± 0.17 Mg C ha⁻¹, with 86.4% occurring in rhizosphere soil. While the carbon budget remained negative, basalt reduced soil carbon loss from 2.69 ± 0.41 to 1.90 ± 0.73 Mg C ha⁻¹. These findings highlight ERW’s potential to mitigate soil carbon loss, warranting further long-term studies.
Porous biochar for improving the CO2 uptake capacities and kinetics of concrete
Mesnage, M., Omnée, R., Colin, J., Ramezani, H., Jeong, J., & Raymundo-Piñero, E. (2025). Porous biochar for improving the CO2 uptake capacities and kinetics of concrete. Cement and Concrete Composites, 105932.
Synopsis: This study explores a sustainable method to enhance carbonation kinetics and CO2 capture in cement materials by incorporating highly porous biochar derived from seaweed pyrolysis. Biochar's surface area, micropores, mesopores, and oxygen-rich groups enable efficient CO2 adsorption and water retention. When embedded in the cement matrix, biochar reservoirs enhance hydration, carbonation, and CO2 diffusion. Experimental data and simulations show that biochar promotes deeper carbonation and calcium carbonate formation, significantly improving CO2 uptake and offering a promising approach to sustainable construction and carbon sequestration.
The Economics of Carbon Dioxide Removal: A Governance Perspective
Edenhofer, O., Franks, M., Gruner, F., Kalkuhl, M., & Lessmann, K. (2024). The Economics of Carbon Dioxide Removal: A Governance Perspective.
Synopsis: Carbon dioxide removal is gaining importance in climate policy. This review examines the emerging economic literature on CDR governance, policy design, and institutions. CDR can enhance climate policy by providing cost-saving flexibilities, aiding climate targets after overshooting, and addressing international cooperation challenges. However, governance complexities arise from non-permanence of carbon storage and firm risks. The review explores price instruments and emissions trading schemes as potential approaches to incentivize CDR.
Evaluating the two-pool decay model for biochar carbon permanence
Sanei, H., Petersen, H. I., Chiaramonti, D., & Masek, O. (2025). Evaluating the two-pool decay model for biochar carbon permanence. Biochar, 7(1), 1-7.
Synopsis: This study critiques the two-pool decay model for estimating biochar carbon permanence, highlighting two key issues: it assigns an overly low labile carbon fraction (C1), leading to overestimated biochar decay, and it misaligns with key carbonization factors like production temperature and H/C ratios. The authors recommend developing a revised multi-pool decay model with improved parameterization, supported by diverse empirical data, to better estimate biochar's carbon sequestration potential and enhance its role in carbon management.
Efficiency metrics for ocean alkalinity enhancements under responsive and prescribed atmospheric pCO2 conditions
Tyka, M. D. (2025). Efficiency metrics for ocean alkalinity enhancements under responsive and prescribed atmospheric p CO2 conditions. Biogeosciences, 22(1), 341-353.
Synopsis: Ocean alkalinity enhancement and direct ocean removal (DOR) offer potential for negative emissions, but their effectiveness is hard to measure due to long equilibration times, subduction, and alkalinity dilution. Measurement, reporting, and verification (MRV) rely on general circulation models constrained by experiments. This study highlights significant differences in CO₂ inventory changes between prescribed pCO₂ models and fully coupled Earth system models due to atmospheric feedbacks, such as CO₂ off-gassing. Metrics like efficiency η(t) are explored, emphasizing their implications for negative emissions credits versus temperature effects.
Carbon burial in sediments below seaweed farms matches that of Blue Carbon habitats
Duarte, C. M., Delgado-Huertas, A., Marti, E., Gasser, B., Martin, I. S., Cousteau, A., ... & Masque, P. (2025). Carbon burial in sediments below seaweed farms matches that of Blue Carbon habitats. Nature Climate Change, 1-8.
Synopsis: Seaweed farming shows promise as a Blue Carbon strategy. A study of 20 global farms (1–15,000 ha, 2–300 years old) found sediment carbon stocks below farms increased with age, reaching 140 tC ha⁻¹ in the oldest farm. Farms buried organic carbon at 1.87 ± 0.73 tCO₂e ha⁻¹ yr⁻¹, double the rate of reference sediments, with an excess burial rate of 1.06 ± 0.74 tCO₂e ha⁻¹ yr⁻¹. This confirms seaweed farms in depositional environments contribute to carbon sequestration, with rates improving over time.
Translating lab success to the field: Evaluating coffee biochar-enhanced concrete in real-world construction
Roychand, R., Kilmartin-Lynch, S., Saberian, M., Li, J., & Li, C. Q. (2025). Translating Lab Success to the Field: Evaluating Coffee Biochar-Enhanced Concrete in Real-World Construction. Case Studies in Construction Materials, e04233.
Synopsis: Building on prior lab research, this study presents the first field trial using coffee biochar in concrete, demonstrating its potential in real-world construction. Previous work showed that biochar from spent coffee grounds (SCGs) pyrolyzed at 350°C could enhance concrete strength by up to 30%. In this field study, biochar-enhanced concrete was tested under actual environmental conditions, with independent tests for slump, compressive and flexural strength, and shrinkage. Despite production challenges at a commercial scale, the study highlights coffee biochar’s promise as a sustainable material, while addressing supply chain constraints for mainstream use.
Navigating stakeholder heterogeneity in carbon dioxide removal governance
Malakar, Y., Brent, K., Bester, A., Gardner, J., Howard, W., & Lenton, A. (2025). Navigating stakeholder heterogeneity in carbon dioxide removal governance. Nature Reviews Clean Technology, 1(1), 95-105.
Synopsis: Governments are turning to Carbon Dioxide Removal to meet net-zero goals, but effective governance requires navigating diverse stakeholders with varying agendas and influence. This Perspective introduces a framework combining multi-level perspective and stakeholder theory to classify stakeholders across the CDR socio-technical system, from niche innovators to regime actors. Understanding relationships and agendas is key to targeted engagement strategies that support responsible and inclusive CDR governance.
Increased but not pristine soil organic carbon stocks in restored ecosystems
Ascenzi, I., Hilbers, J. P., van Katwijk, M. M., Huijbregts, M. A., & Hanssen, S. V. (2025). Increased but not pristine soil organic carbon stocks in restored ecosystems. Nature Communications, 16(1), 637.
Synopsis: Ecosystem restoration enhances climate mitigation by increasing soil organic carbon stocks. A second-order meta-analysis of 41 studies shows significant SOC gains in 12 of 16 ecosystem-land use combinations, with increases ranging from 25% in grasslands to 79% in shrublands. However, restored ecosystems still exhibit SOC deficits compared to pristine sites (14%–50%). While restoration boosts SOC sequestration, conserving natural ecosystems remains essential for fully offsetting carbon losses.
Soil moisture controls over carbon sequestration and greenhouse gas emissions: a review
Hao, Y., Mao, J., Bachmann, C. M., Hoffman, F. M., Koren, G., Chen, H., ... & Dai, Y. (2025). Soil moisture controls over carbon sequestration and greenhouse gas emissions: a review. npj Climate and Atmospheric Science, 8(1), 16.
Synopsis: This review explores soil moisture's critical role in carbon sequestration and greenhouse gas (CS-GHG) regulation. Optimal soil moisture boosts carbon storage, while extremes disrupt processes like photosynthesis and microbial activity. CO₂ emissions peak at 40% water-filled pore space (WFPS), with CH₄ and N₂O peaking at 60–80% and ~80% WFPS, respectively. Sustainable practices like agroforestry and optimized water management enhance CS-GHG outcomes. Advanced modeling and policy shifts toward long-term carbon goals are vital for effective climate mitigation.
Assessing and Optimizing the Potential for Climate Change Mitigation and Carbon Sequestration in Urban Residential Green Spaces: Energizing Sustainable Cities
Liu, H., Zhang, J., & Wang, Z. Assessing and Optimizing the Potential for Climate Change Mitigation and Carbon Sequestration in Urban Residential Green Spaces: Energizing Sustainable Cities. Frontiers in Environmental Science, 13, 1519297.
Synopsis: This study assessed the carbon sequestration potential of 20 plant species in urban green spaces across Nanjing, China. Results revealed significant differences in sequestration capacities: evergreen trees excelled in both daily and total carbon sequestration, followed by deciduous trees, evergreen shrubs, and deciduous shrubs. Seasonal variations showed higher sequestration in summer and autumn. Optimization strategies, such as prioritizing evergreen trees and diverse plant integration, can enhance year-round sequestration, supporting sustainable urban planning and climate mitigation.
Assessing the effect of forest management on above-ground carbon stock by remote sensing
Van Winckel, S., Simons, J., Lhermitte, S., & Muys, B. (2025). Assessing the effect of forest management on above-ground carbon stock by remote sensing. EGUsphere, 2025, 1-22.
Synopsis: This study utilized Sentinel-2, Sentinel-1, and GEDI-derived canopy height data to enhance forest carbon stock estimation through a generalized additive model (GAM). Combining these remote sensing sources improved model accuracy (R²=0.68, RMSE=56.35) over Sentinel-2 alone. Field assessments revealed higher carbon stocks in unmanaged forests, but this difference was undetectable in the remote sensing model, likely due to signal saturation and limited training data. Findings underscore the potential and challenges of integrating multi-sensor data for sustainable forest management.
Investigating CO₂ sequestration via enhanced rock weathering: Effects of temperature and citric acid on dolomite and basalt
Xu, Q., Zhang, F., Song, F., Guo, H., Wang, X., Bi, F., & Xu, M. (2024). Investigating CO₂ sequestration via enhanced rock weathering: Effects of temperature and citric acid on dolomite and basalt. Journal of Cleaner Production, 485, 144414.
Synopsis: This study evaluated CO₂ sequestration via enhanced rock weathering (ERW) using dolomite and basalt under elevated temperature and citric acid influence in a 90-day leaching experiment. Dolomite achieved higher Mg-based CO₂ sequestration rates (10.15–14.91 kg CO₂ t⁻¹ yr⁻¹) than basalt (2.88–11.85 kg CO₂ t⁻¹ yr⁻¹). Citric acid boosted basalt sequestration by 224.
Integrated direct air CO2 capture and utilization via in-situ catalytic conversion to fuels and chemicals using dual functional materials: Recent progresses and perspectives
Zhang, Y., Feng, J., Li, L., Zhao, S., Wu, C., Huang, Z., & Lin, H. (2025). Integrated direct air CO2 capture and utilization via in-situ catalytic conversion to fuels and chemicals using dual functional materials: Recent progresses and perspectives. Frontiers in Energy, 1-13.
Synopsis: This review explores the potential of integrated direct air capture and utilization (IDACU) technologies, which combine CO₂ capture with in-situ catalytic conversion to fuels and chemicals. It covers various technical approaches, including solid-based dual-functional materials (DFMs) via thermo-catalysis, liquid sorbent-based IDACU, and non-thermal conversion methods. The review highlights advancements in solid-based DFMs, differences in materials for flue gas and DAC capture, and challenges in material design. Despite promising potential, IDACU still faces significant hurdles in development.
The impact of regional resources and technology availability on carbon dioxide removal potential in the United States
Javadi, P., O’Rourke, P., Fuhrman, J., McJeon, H., Doney, S. C., Shobe, W., & Clarens, A. F. (2024). The impact of regional resources and technology availability on carbon dioxide removal potential in the United States. Environmental Research: Energy, 1(4), 045007.
Synopsis: To achieve net zero carbon emissions by mid-century, the U.S. may need to rely on Carbon Dioxide Removal to offset emissions from hard-to-decarbonize sectors. Using the GCAM-USA model, six CDR approaches were explored under four scenarios. The Full Portfolio scenario predicts the U.S. could remove 1-1.9 GtCO₂/yr, with Direct Air Carbon Capture and Storage (DACCS) contributing 50%, bioenergy with CCS 25%, and Enhanced Rock Weathering (ERW) 11.5%. CDR deployment impacts energy, land, and materials supply chains, with regional disparities in deployment.
Emissions trading systems: Trading removals?
La Hoz Theuer, S., Doda, B., Acworth, W., & Kellner, K. (2024). Emissions trading systems: Trading removals?. Climate Policy, 1-16.
Synopsis: This study examines how emissions trading systems (ETSs) could interact with carbon dioxide removal strategies. Four interaction options are identified: 'disconnected markets', 'connected through government', 'connected with restrictions', and 'integrated markets'. These differ in government control, cap-setting flexibility, price discovery, market expectations, and fiscal burden. The study highlights key design considerations, including fungibility of emissions and removals, allocation of credits, limits on removal units, and timing for inclusion, suggesting that different approaches may work in varied contexts.

JOB OPPORTUNITIES
PhD Studentship: Direct Air Capture - Process modelling and scaling up material production & PhD Studentship: Direct Air Capture - Carbon sponge development at University of Cambridge | Deadline: 16 May 2025
"The Forse Group in the Yusuf Hamied Department of Chemistry are working on “direct air capture”, an approach where sponge-like materials are used to capture carbon dioxide directly from the atmosphere. The traditional sponge materials for this process have issues including poor long-term stability and/or the need for very high temperatures (up to 900 ºC) to regenerate the sponges for reuse.
To tackle these issues, the Forse Group recently pioneered a new approach to make carbon sponges. Starting with cheap and readily available activated charcoal, the team developed a “charging” method similar to the charging of a battery. This process charges alkaline hydroxide molecules into the porosity of the charcoal to enhance its carbon capture ability. These materials show promising direct air capture performance, and they are stable, cheap, and can be regenerated at low temperatures (~100ºC). The group’s breakthrough study was recently published in Nature in 2024 and was highlighted in over 100 news stories, including in the BBC, The Independent, and CNN."

The GigaTen Ep. 2 January 2025 | Tree Media
"Sebastian Manhart updates us on the CDR (carbon dioxide removal) industry in conversation with Leila Conners. The GigaTen is a newsletter that Sebastian posts monthly and Leila thought it would be an interesting conversation to update monthly as well. We think that CDR is important and a unifying pathway as it creates jobs, proposes new ways to manufacture materials and can remove CO2 as needed."
Misconception: Microalgae and Anoxic Zones | Ocean Iron Fertilization | Liquid Trees
"Victor and Daniel address misconceptions about ocean iron fertilization, explaining the role of iron in marine ecosystems, the impact of whale population decline, and the complex interactions between various forms of marine life. They clarify the science behind nutrient cycles, discuss the causes and effects of anoxic zones in the Baltic Sea, Gulf of Mexico and Florida, as well as the potential benefits of restoring iron levels in the ocean."
Iron Restoration: Profits, Politics & The Planet | Ocean Iron Fertilization | Liquid Trees
"Victor and Daniel discuss the benefits and opposition of ocean iron fertilization, arguing it can restore marine ecosystems. They propose legal frameworks to mandate iron replenishment by fishing vessels, especially in the Southern Ocean, and critique the motivations driving the debate."
Science Comedy: Tyler Rohr - Oceans & carbon | Future Science Talks
"In this Future Science Talks: Comedy Edition show at the 2024 Australian Antarctic Research Conference in Hobart, Tyler Rohr from Institute of Marine and Antarctic Studies discusses his efforts in trying to figure out how the ocean keeps carbon out of the atmosphere."
