RESEARCH PAPERS
A blueprint for national assessments of the blue carbon capacity of kelp forests applied to Canada’s coastline
Authors: Jennifer McHenry, Daniel K. Okamoto, Karen Filbee-Dexter, Kira A. Krumhansl, Kathleen A. MacGregor, et al.
Synopsis: This study presents a blueprint for estimating kelp forests' carbon sequestration potential using data synthesis and Bayesian modeling. Applied to Canada, kelps store 0.6–2.8 Tg C and export up to 0.4 Tg C/year to the deep ocean. Though modest, kelp sinks rival wetlands and merit inclusion in national climate inventories.
Separating CO2 emission from removal targets comes with limited cost impacts
Authors: Anne Merfort, Jessica Strefler, Gabriel Abrahão, Nico Bauer, Tabea Dorndorf, Elmar Kriegler, et al.
Synopsis: This study explores setting separate targets for emissions and novel CDR in net-zero pathways using the REMIND model. While this reduces efficiency slightly, it offers key benefits: lower cumulative emissions, reduced public CDR costs, and less reliance on geologic storage—though biomass demand remains high. Clear targets are still needed to ensure enough CDR for net-negative emissions later this century.
Scaling carbon removal without delaying emission reductions
Authors: Jeffrey Dankwa Ampah, Chao Jin, Haifeng Liu, Felix Schenuit, Sandylove Afrane, Humphrey Adun, David T. Ho, et al.
Synopsis: Depending on policy design, carbon dioxide removal could either perpetuate fossil fuel consumption and slow emission reductions or, if paired with rapid emission reductions, accelerate net-zero attainment and minimize overshoot periods. Policies that simultaneously and separately mandate emission reductions and near-term carbon dioxide removals could help to prevent mitigation deterrence, while supporting the upscaling of carbon dioxide removal.
Exploring global climate intervention experiments: sociotechnical promises, innovation dynamics, and perceived co-impacts across 20 projects and pilots
Authors: Benjamin K. Sovacool, Chad M. Baum, Livia Fritz & Sean Low
Synopsis: This study uses participatory action research and ethnographic methods to analyze 20 real-world experiments across carbon removal and solar radiation modification techniques—from engineered solutions like DAC and SAI to nature-based approaches like afforestation and coral reef restoration. Drawing on 118 interviews and site observations, the research investigates actor coalitions, their promises, innovation dynamics, and perceived co-impacts. Findings illuminate how these influential, well-funded experiments are shaping the future of climate intervention policy and practice.
Effects of Long-Term CO2 Storage on Carbonate Rock Stability
Authors: Hani Almukainah, Abdulameer Almalichy, Mohamed Mahmoud, Murtada Saleh Aljawad, et al.
Synopsis: This study evaluates limestone’s integrity under CO₂ sequestration conditions. Limestone cores were exposed to CO₂-rich brine at 60 °C and 2000 psi for 60 days. Results showed increased porosity and tortuosity, minimal wormhole formation, and no loss of structural stability—supporting limestone’s suitability for long-term carbon geostorage.
Considering durability in carbon dioxide removal strategies for climate change mitigation
Authors: Charlotte Streck, Sara Minoli, Stephanie Roe, Christian Barry, Matthew Brander, Solene Chiquier, et al.
Synopsis: This Perspective examines the concept of CDR durability—defined by storage duration and reversal risk—and its role in policymaking. Engineered CDR methods offer longer-term stability, while nature-based methods are vital for near-term balance. The authors advocate for policies that recognize varied durability profiles and recommend mixed CDR portfolios combining both types to optimize durability, feasibility, and sustainability across timeframes.
Co-existence strategies and carbon sequestration contributions of bacterial generalists and specialists in natural wetlands under land use and land cover change
Authors: Jiayuan Liu, Ning Zhang, Sen Zhang, Hailong Wu, Fude Liu
Synopsis: This global study analyzes how land use and cover change (LULCC) affects bacterial communities in natural wetlands (NWs) and their role in carbon cycling. Using 1,124 samples, it finds that generalists, more than specialists, show higher community turnover after LULCC. LULCC shifts species interactions from competition to cooperation and reduces generalists' metabolic function—weakening carbon sequestration. These insights help improve carbon cycle models by incorporating microbial roles.
Unlocking the Potential of Bioenergy with Carbon Capture and Sequestrations in Africa
Authors: Chidiebele EJ Uzoagba, Azikiwe Peter Onwualu
Synopsis: This review explores the potential for developing a BECCS (Bioenergy with Carbon Capture and Storage) market in Africa, despite the continent’s vast untapped bioenergy resources. It examines BECCS technology, its climate and development benefits, and the technical, economic, and policy challenges to implementation. The study offers strategies and policy recommendations to build a sustainable BECCS market aligned with Africa’s development and bioenergy goals.
TimberTracer: a comprehensive framework for the evaluation of carbon sequestration by forest management and substitution of harvested wood products
Authors: I. Boukhris, A. Collalti, S. Lahssini, D. Dalmonech, F. Nakhle, R. Testolin, M. V. Chiriacò, M. Santini & R. Valentini
Synopsis: This study uses the TimberTracer framework with the 3D-CMCC-FEM model to assess harvested wood products' (HWPs) climate mitigation role. In Italy's Bonis watershed, selective thinning and a 10% rise in both recycling and product lifespan offered the best carbon outcomes. Ignoring landfill methane and using static substitution factors can overstate mitigation potential, highlighting the need for comprehensive accounting in HWP-based climate strategies.
Techno-economic assessment of high temperature heat pumps integrated in MEA-based post-combustion CO2 capture for cement plant
Authors: Riccardo Cremona, Edoardo De Lena, Antonio Conversano, Maurizio Spinelli, Matteo C. Romano, Manuele Gatti
Synopsis: This study assesses solvent-based CO₂ capture in cement production using either natural gas boilers or high-temperature heat pumps (HTHPs). The best NG boiler setup yields a CO₂ avoidance cost of €149.6/t. HTHPs, especially MVR-based systems with lean vapor compression, reduce this to €125.9/t with better energy efficiency. Simulations show HTHPs can cut thermal demand by using waste heat, aiding cement decarbonization despite increased electricity use and Scope 2 emissions.
Soil carbon formation is promoted by saturation deficit and existing mineral-associated carbon, not by microbial carbon-use efficiency
Authors: Alison E. King and Noah W. Sokol
Synopsis: This study challenges the view that existing mineral-associated organic carbon (MAOC) limits new carbon storage. Using soils from 15 U.S. agricultural sites, researchers found that both existing MAOC and its saturation deficit actually promote further MAOC formation, regardless of soil properties. Contrary to theory, microbial carbon-use efficiency had little effect. These findings highlight MAOC levels and saturation deficit—not CUE—as key drivers of new MAOC buildup in soils.
Critical Review on Feasibility and Challenges of Coupling Direct Air Capture with Renewable Energy
Authors: Yihe Miao, Roman Selyanchyn, Yuhang Liu, Zixin Zhang, Shigenori Fujikawa, Lijun Yu
Synopsis: This review explores how DAC can be effectively integrated with renewable energy to support global net-zero goals by 2050. It examines three key DAC pathways and assesses their compatibility with renewables. While DAC’s sustainability depends on clean energy, few studies address how to manage renewable supply fluctuations. This review highlights that bridging this gap is essential for viable, large-scale DAC deployment and outlines key challenges and future research needs.
Parameter optimization of the direct air capture (DAC) process to achieve net zero emission targets
Authors: Udara Pahalagama Ranathunga Arachchige
Synopsis: This study uses Aspen Plus simulations to optimize DAC systems for cost-effective CO₂ removal. Key findings show a 75% capture rate at 760 t/h Ca(OH)₂ flow and 1.1 atm air pressure. Structured packing (BX) boosts efficiency over Mellapak types. Sensitivity analysis highlights how variables like solvent concentration, temperature, and moisture affect performance. Results guide more efficient, economical DAC designs to support net zero goals.
Efficacy of seaweed-based carbon dioxide removal reduced by iron limitation and nutrient competition with phytoplankton—Preprint
Authors: Manon Berger, Lester Kwiatkowski, Laurent Bopp, David T. Ho
Synopsis: Ocean afforestation using seaweed is a promising carbon removal strategy, but most models overlook iron limitation, a key constraint. Using a biogeochemical model, researchers show that iron scarcity can cut CDR potential by threefold, even after factoring in nitrogen and phosphorus. Competition with phytoplankton may even lower ocean carbon uptake. CDR efficiency varies widely (-43% to +78%), highlighting the need to include iron dynamics in future seaweed-based mitigation assessments.

Efficient Integration of Direct Air Capture With HVAC System
Authors: Yasser Mohamed Mohamed Taher Abdellatif
Synopsis: This thesis investigates integrating DAC with HVAC systems to reduce costs and energy use while improving CO₂ removal and indoor air quality. Modeling and experiments show DAC efficiency can rise from 5.3% to 27.2%, and energy use drops with advanced sorbents like S-PEI-L. Integrating DAC with HVAC cuts the levelized cost of CO₂ capture from $349–$429 to as low as $184/ton and reduces building cooling energy use by ~30%, advancing DAC as a viable, infrastructure-ready solution.
Bridging the Commercialization Gap for the Direct Air Capture of Atmospheric CO2
Author: Wenger, Samuel Ryan
Synopsis: This thesis systematically investigates challenges and innovations in scaling DAC. Chapter 2 argues that DAC’s higher cost per tonne of CO₂ should be weighed against its value in long-duration storage—unlike nature-based CDR. Chapters 3–4 explore solid-state DAC materials, including a novel MOF (UiO-66-NH₂) and its functionalization for electrochemical CO₂ capture. Chapters 5–6 shift to solution-phase DAC, developing redox-active organic systems and an efficient, green electrochemical process with promising energy and cost metrics.

How Cities Will Lead on Carbon Removal: Embedding CDR in Sub-National Political Units—w/ Christiaan Gevers Deynoot, Founder of City CDR Initiative | Reversing Climate Change
"Everyone thinks of national and international governments leading or failing on climate change. But what about cities and smaller political entities? How can they lead on climate and carbon removal when larger entities may be focused elsewhere? Since carbon removal infrastructure is likely to end up at least partially within urban or periurban environments, how can we prepare ourselves and our policies for such a near-term future?
To answer these and so many more questions, Christiaan Gevers Deynoot, the Founder and Program Lead of the City CDR Initiative joins host Ross Kenyon (who also serves as a Strategic Advisor, Communications for the City CDR Initiative.)
This becomes a discussion about the big questions of political order, whether we prefer bottom-up experimentation and ferment or top-down legibility and scale, and to what degree the agony and the ecstasy of central planning may be present for CDR at the municipal level."

The Enduring Challenge of Carbon Dioxide Removal Durability | Remove and Reflect Podcast
"This episode covers a document, titled "Considering durability in carbon dioxide removal strategies for climate change mitigation," published in Climate Policy, that examines the crucial concept of durability in Carbon Dioxide Removal (CDR) methods. It highlights that durability involves both the duration of CO2 storage and the risk of its reversal, which vary significantly between nature-based and engineered CDR approaches. The paper argues for a complementary portfolio of CDR strategies, emphasizing that while engineered methods often offer greater stability, nature-based solutions are more immediately deployable and offer co-benefits. Ultimately, the authors advocate for policies that consider the diverse risk profiles and timings of different CDR methods to achieve long-term climate goals effectively."

"Enhanced Rock Weathering (ERW) is emerging as one of the most promising carbon removal solutions on the planet—and Brazil is uniquely positioned to lead its global breakthrough. The country’s vast reserves of basalt and other mafic rocks are already being mined and used as soil amendments to reduce acidity and improve fertility. These rock powders are exceptionally well-suited to Brazil’s acidic, nutrient-depleted tropical soils, where they not only boost crop yields but also accelerate the natural process of carbon dioxide removal."
Workshop: Implementing A Low Carbon Concrete Building Code in your City. | OpenAir
"Concrete is the most widely used building material on earth—foundational to roads, bridges, buildings, and virtually all modern infrastructure. Yet, it is also a major contributor to greenhouse gas emissions, primarily due to the production of cement, its key binding ingredient. Fortunately, there are proven materials and methods that can significantly reduce the embodied carbon of concrete with minimal or no added cost. Local governments play a critical role in enabling this shift by adopting low-carbon concrete standards into their building codes."
