RESERACH PAPERS
State-of-the-Art Membrane Solutions for Direct Air Carbon Capture (DACC): An Overview on the Current Status and Future Directions
Authors: Syed Awais Ali, Syed Nasir Shah, Malik Abdul Karim, et al.
Synopsis: A quarter of global CO₂ emissions come from small, diffuse sources that are hard to capture conventionally. Direct air carbon capture (DACC) offers a solution but is costly due to CO₂'s low atmospheric concentration. This review explores membrane-based DACC (m-DACC) as a promising alternative, highlighting recent advances in materials, performance, and cost-efficiency. It offers a roadmap for scaling m-DACC and guiding future research and industrial adoption.
Potential of Co-practicing Enhanced Rock Weathering and Geologic Carbon Storage
Authors: Hang Deng, Qi Li
Synopsis: Geologic carbon storage (GCS) is key for climate goals, but leakage risk remains. Enhanced rock weathering could help mitigate CO₂ seepage while offering co-benefits like carbon removal and groundwater protection. ERW may act as a buffer for low to moderate leaks and supports shared monitoring with GCS. Co-practicing GCS and ERW holds promise but faces challenges in regulation, coordination, and life cycle impacts—warranting further research and integrated assessments.
Modeling and Feasibility Assessment of Mineral Carbonation Based on Biological pH Swing for Atmospheric CO2 Removal
Authors: Yukun Zhang, Spencer Long, Manon T. Duret, Liam A. Bullock, Phyllis Lam, Aidong Yang
Synopsis: This study explores a novel biological pH swing method for CO₂ removal via mineral carbonation at ambient conditions. Using sulfur-reducing and -oxidizing microbes, pH cycles promote silicate dissolution and carbonate precipitation. Modeling shows CO₂ removal is feasible, with thiosulfate offering advantages over hydrogen sulfide. Key limits include gas–liquid transfer and mineral dissolution rates. The study highlights promising potential and areas for further investigation.
Influence of surface coal mining on carbon storage in semi-arid steppe
Authors: Zhenhua Wu & Qiao Yu
Synopsis: This study analyzes carbon storage changes in a semi-arid steppe coal mining area (2002–2023) using the InVEST model. Findings show a 187.15 kt total carbon loss, with mining alone causing 91.92 kt loss. Land conversion to lower carbon-density types weakened carbon sequestration. Most areas showed little change, but 23.63% saw decreases. Results offer insight for ecological restoration and support low-carbon goals in mining regions.
Harnessing Microbes to Weather Native Silicates in Agricultural Soils for Scalable Carbon Dioxide Removal
Authors: Tania Timmermann, Christopher Yip, Yun-Ya Yang, Kimberly A. Wemmer, et al.
Synopsis: This study demonstrates that Bacillus subtilis strain MP1 enhances silicate weathering, potentially aiding climate change mitigation. MP1 promotes silicate dissolution, pH increase, and calcium carbonate formation in culture experiments. In mesocosms, it boosted silicate weathering rates by over six times and increased soil inorganic carbon by 20%. Applied to soybean fields, MP1 resulted in an annual accrual of 2.02 tonnes of inorganic carbon per hectare. This highlights the potential of microorganisms to enhance soil carbon storage in agriculture.
Explosive volcanic eruptions can act as carbon sinks
Authors: Pierre Delmelle, Sébastien Biass, Mathilde Paque & Benjamin Lobet
Synopsis: Volcanic soils, though covering ~1% of land, hold over 5% of global soil organic carbon. This study shows that explosive eruptions bury large amounts of stable carbon via tephra fallout. Modeling suggests Ecuador’s volcanic soils alone have stored at least 1.1 Pg C during the Holocene—more than the CO₂ emitted by the eruptions. Thus, explosive volcanism can act as a long-term regional carbon sink, making such events net carbon-negative over time.
Spatio-temporal variations in carbon sources, sinks and footprints of cropland ecosystems in the Middle and Lower Yangtze River Plain of China, 2013–2022
Authors: Jing Kong & Yisong Li
Synopsis: This study analyzes carbon dynamics in cropland ecosystems of China’s Middle and Lower Yangtze River Plain (2013–2022). Results show rising carbon uptake (notably in paddy and wheat), declining emissions (mainly from fertilizer and irrigation), and a fluctuating but decreasing carbon footprint. Croplands acted as carbon sinks, though ecological surplus is weakening. Promoting green manure and precision agriculture is key to enhancing carbon efficiency and meeting climate goals.
A critical analysis of marine carbon sequestration opportunities in South Korea
Authors: Peter I. Macreadie, Finnley W. R. Ross, Carlos M. Duarte, Ji Won Hong, Ho-Sung Yoon
Synopsis: This study revealed that South Korea aims to sequester 1.36 million tonnes of CO₂ in the ocean by 2050 as part of its climate strategy. The country is exploring various marine carbon sequestration methods, from blue carbon conservation/restoration of seagrass and tidal marshes to emerging strategies like seaweed farming and ocean alkalinity enhancement. While achievable, the target requires coordinated efforts and strong policy support. South Korea's expertise in seaweed sequestration positions it well for meeting this goal, aligning with broader environmental objectives.
Public Engagement and Carbon Dioxide Removal
Authors: Albert Lin
Synopsis: As CDR techniques like direct air capture and storage gain attention, public engagement remains inadequate. While DACS offers potential for large-scale carbon storage, its high costs and energy demands hinder widespread deployment, and local opposition often arises due to safety and environmental concerns. The article highlights the need for both policy-level public engagement to guide CDR efforts and project-level engagement to address community concerns and secure social acceptance for DACS projects.
Assessing the implications of EU Nature Restoration Law targets from carbon sequestration and biodiversity perspectives in a high-green urban environment
Authors: Antti Kinnunen, Ranja Hautamäki, Jaana B. Junnila, Joel Jalkanen, et al.
Synopsis: This study in Helsinki examined the European Union's Nature Restoration Law’s impact on carbon sequestration and biodiversity under various development scenarios. The findings suggest that while the law improves environmental outcomes, urban density challenges remain. The study advocates for integrating quantitative targets with locally tailored actions for effective implementation.
South Asia's Ecosystems Are a Net Carbon Sink, But the Region Is a Major Net GHG Source to the Atmosphere
Authors: Atul K. Jain, Seetharaman Seshadri, Jatin Anand, Naveen Chandra, et al.
Synopssi: The RECCAP-2 project estimates GHG budgets for South Asia from 2010-2019, analyzing emissions and sinks for CO2, CH4, and N2O. The study finds a 34%–43% rise in GHG emissions compared to the 2000s, driven by industrial activities. Despite this, terrestrial ecosystems acted as a CO2 sink, albeit smaller than emissions. SA’s total emissions accounted for 8% of global emissions, with India being the largest emitter (80% of regional emissions), followed by Pakistan (10%) and Bangladesh (7%).
A Dataset for Investigations of Amine-Impregnated Solid Adsorbent for Direct Air Capture
Authors: Eryu Wang, Liping Luo, Jiachuan Wang, Jiaxin Dai, Shuangyin Li, Lei Chen & Jia Li
Synopsis: This study analyzes 52 articles on amine-impregnated solid adsorbents for CO2 capture, including DAC, using a GPT-assisted screening method. The research compiles 1,336 data points with 28 features, resulting in 29,857 records. It addresses inconsistencies in units and terminology, ensuring dataset reliability and integrity. The study highlights the potential for innovation in amines and mesoporous solids, and encourages data sharing and uniform reporting in DAC research, with machine learning models promoting dataset reuse.
Direct measurement of carbon dioxide removal due to enhanced weathering - Preprint
Authors: Ella Milliken, Alex Woodley, Noah Planavsky
Synopsis: This study monitors a basalt-applied soybean plot in Southeast Virginia to measure CO2 flux reduction, using continuous in-soil CO2 monitors. The results show a CO2 removal rate of 1.04 t ha-1 yr-1, particularly during the growing season and after heavy rain. The findings demonstrate that enhanced weathering (EW) can be a scalable, durable carbon removal strategy. Continuous gas-phase measurements are crucial for advancing understanding of EW rates and their timescale for effective carbon removal.

PODCASTS
Beyond Offsets: How to Build a Carbon Removal Industry | Disruptors
"Carbon offsets aren’t enough. To truly tackle climate change, we need a global industry dedicated to pulling carbon out of the air and at massive scale. Join hosts John and Sonia inside the innovation race to scale carbon removal technologies, featuring insights from leading voices in the field.
They speak with Dr. David Keith, a pioneering climate scientist and founder of Carbon Engineering, who unpacks the technological, policy, and economic hurdles to direct air capture and other approaches. You’ll also hear from two recent XPRIZE Carbon Removal winners, Mike Kelland of Planetary Technologies and Jim Mann of UNDO about how their startups are using ocean alkalinity and enhanced rock weathering to permanently sequester CO₂, while also delivering benefits to farmers and marine ecosystems.
Together, they explore whether the world can build a scalable, measurable, and credible carbon removal industry – one capable of drawing down billions of tons of CO₂ annually."
CDR Policy Deep Dive - Part 1: From Kyoto to Carbon Removal | The Carbon Removal Show
"In this episode:
-Policy 101: What do we mean when we talk about carbon removal policy? Tom, Emily and their guests unpack the layers - from global frameworks to national targets, and the many policies themselves that can (hopefully) keep this show on the road.
-A Brief History of Climate Governance: We rewind all the way to the UNFCCC, the Kyoto Protocol, and the Paris Agreement, to understand the context in which CDR policy is emerging. Turns out, carbon removal has technically been part of the discussion for some time - but it took a while to step out of the LULUCF shadows and into the limelight.
-The Goals of CDR Policy: Whether it’s support for scaling the industry or regulation for doing it right, we explore the many roles that policy can play in ensuring CDR does what it’s supposed to. Who should pay for it? How can we avoid unintended consequences? And is it too late to bribe policymakers with Emily’s banana bread?
-It’s All Connected: We learn that CDR doesn’t happen in a vacuum – and that means CDR policy can’t either. It's entangled with everything from energy to land use to ocean governance. And yes, ocean-based CDR is complicated when 40% of the sea has no nation.
-The Bony Meat Pie Metaphor™: How do NDCs, interim targets and policies work together to meet(/meat?) our climate goals? It’s all very clever, but not especially appetising.
-Avoiding Déjà Vu: We ask what we can learn from previous climate and environmental policies – so we don’t spend the next decade reinventing the wheel, crashing it into a forest, and accidentally calling it carbon neutral."
Technology vs Transition?: What Tony Blair gets right - and wrong - about net zero | Outrage + Optimism
"Former UK Prime Minister Tony Blair says that net zero is politically unachievable without radical rethinking: a shift away from reducing consumption and toward technologies that can remove carbon both at the source and from the atmosphere. So, are carbon capture and carbon removal really viable - and more palatable - alternatives to a rapid fossil fuel phaseout? And is our net zero strategy failing, or simply failing to be explained?
Hosts Christiana Figueres, Tom Rivett-Carnac, and Paul Dickinson dive into the heart of these questions and explore what Blair’s comments mean for the wider net zero debate. At a time when climate action is becoming increasingly politicised and weaponised, they consider how we might frame net zero as something that improves people’s lives, rather than threatening them. And how we can ensure that every credible climate solution stays on the table."

Genetically Enhanced Crops for Carbon Removal | Remove and Reflect Podcast
"This episode delves into a recent paper that introduces a novel approach to assessing the scalability of carbon dioxide removal (CDR) strategies by integrating technological change theories with historical analogs. The authors focus on genetically enhanced crops designed to increase root mass and depth, thus enhancing soil carbon storage. They argue that because agricultural innovations like genetically modified (GM) crops have scaled rapidly through existing infrastructure, carbon-enhanced crops could achieve significant CO2 removal quickly, potentially peaking within 13 years of initial deployment. However, the major uncertainty lies in political acceptance, particularly the willingness of countries and regions currently resistant to GM crops to adopt these new cultivars, which significantly impacts the total land area available for deployment and thus the overall CO2 removal potential. While technological factors also play a role, the analysis highlights political decisions as the dominant influence on the scale of impact."
Community Views on Marine Carbon Dioxide Removal | Remove and Reflect Podcast
"This episode covers a research article that explores community perspectives on ocean alkalinity enhancement (OAE), a marine-based approach to carbon dioxide removal (CDR). The study conducted workshops with coastal community members in the Olympic Peninsula, Washington State, a region of interest for OAE research and deployment. Through scenario-based activities, researchers found that views on OAE extended beyond ecological concerns to encompass political, economic, and environmental justice dimensions. Participants expressed preferences for OAE configurations involving existing infrastructure, integration with established sectors, and community or Tribal ownership, while also highlighting tensions related to climate urgency, deployment scale, and impact location. The study emphasizes the importance of engaging communities to understand diverse perspectives and inform responsible OAE governance."
