THIS WEEK’S TOP CDR HIGHLIGHTSTRILLION-DOLLAR CARBON REMOVAL NEEDED: Johan Rockström of the Potsdam Institute for Climate Impact Research, who is one of the chief scientific advisers to the UN and the COP30 presidency says roughly 600 billion tonnes of CO₂ must be removed by 2100 to keep a 5% annual emissions-cut pathway aligned with returning to 1.5 °C, and about 10 billion tonnes per year will be needed to avoid tipping points. Delivering this would require a trillion-dollar-a-year CDR industry, alongside a fossil phaseout, food-system shifts, major nature investments, and cuts in non-CO₂ gases. HIDDEN COST OF CAPITAL IN CDR: Noah McQueen highlights that carbon removal costs hinge not just on technology but on who pays. Private financing can make projects 2-3× more expensive than public funding, creating a major hidden hurdle “cost of money.” He notes that with public financing removal could cost about $171/tCO₂, but with first-of-a-kind private lending rates it can climb to ~$322/tCO₂. He argues that without cheaper capital, scaling carbon removal will remain prohibitively costly and slow deployment. CALL FOR EXPERTS: The UK government is calling for expert nominations to contribute to the 2027 IPCC Methodology Report on CO₂ Removal & CCUS. The report, set for completion in 2027, will update national greenhouse gas inventory methods to reflect new carbon‑removal and storage technologies. Deadline: 07 December 2025 CALL FOR PROPOSALS: The Carbon to Sea Initiative, MEOPAR, and Planetary Technologies have launched a new Joint Learning Opportunity to advance ocean alkalinity enhancement research in Halifax. The program will fund work on OAE knowledge gaps, improved monitoring, and social science on public perception. Proposals are due January 9, 2026. 2025 GLOBAL CARBON BUDGET REPORT: The 2025 Global Carbon Budget report, published alongside a new Nature paper, finds fossil CO2 emissions are projected to reach a record 38.1 Gt in 2025, up 1.1% from last year. With land-use emissions (e.g., deforestation) down to 4.1 Gt, total CO2 emissions are slightly below 2024 levels. The report also finds that climate change has weakened land and ocean sinks, contributing 8% to CO2 rise since 1960 and leaving the 1.5°C carbon budget nearly exhausted. Findings are summarized here and here. LARGEST DAC PILOT IN JAPAN: Japan’s Kawasaki Heavy Industries has launched its largest direct‐air capture pilot at its Kobe plant, capturing 100-200 t CO₂/year using a low‑heat (60 °C) sorbent powered by waste heat. It aims to scale to 0.5-1 Mt/year by 2030 - one of Asia’s biggest DAC systems.

G. Mason, Bahareh Bicharanloo, Matthias Salomon, Andrew Lowe, Feike A. Dijkstra & Timothy CavagnaroSynopsis: This study introduces the Hyphal Carbon Transfer Theory, showing that arbuscular mycorrhizal fungi (AMF) transport plant-derived carbon to stable soil pools. Using ¹³C labelling, the authors demonstrate that AMF enhance carbon retention in soil and biochar-associated microsites, shifting C away from the highly respired root zone. Findings reveal a key fungal-mediated pathway for long-term soil carbon stabilization, highlighting the combined roles of microbial transport and biochar in enhancing sequestration.
Authors: Sebastian Löbner, Ashour A. Ahmed, Majid Namayandeh Jorabchi, Alexander Wotzka, et al.Synopsis: This study presents a simple CO₂ direct air capture (DAC) method using ZSM-5 and ion-exchanged zeolites, achieving effective CO₂ concentration from humid air at 5 °C and recovery at 25 °C. Adsorption–desorption cycles demonstrate adsorbent stability, while Monte Carlo and molecular dynamics simulations reveal preferential CO₂ uptake via electrostatic interactions with minimal H₂O interference. Results offer experimental and theoretical insights for scalable, zeolite-based CO₂-DAC applications.
Authors: Yun-Ya Yang, Clifton P Bueno de Mesquita, Corey R Lawrence, Philip D Weyman, Daniel Dores, et al.Synopsis: This study tests combined enhanced weathering (basalt) and microbial CO₂ mineralization (Bacillus subtilis MP1) in slightly acidic soil over 91 days. Basalt strongly shaped soil bacterial communities, while MP1 persisted and modestly influenced composition. Co-application increased soil carbonate alkalinity and total carbon more than either treatment alone, mitigating basalt-induced organic carbon losses. Findings suggest pairing MP1 with basalt can enhance carbon dioxide removal efficiency through synergistic biogeochemical effects.
Authors: Laurie Waller, Emily Cox, Amy Binner, Tatiana Cantillo Garcia, Rosie Everett, Karen Henwood, et al.Synopsis: This perspective examines responsible research and innovation (RRI) in UK field trials of carbon removal methods. Unlike novel geoengineering, many land-based approaches are long-deployed and well-governed, making traditional RRI frameworks only partially suitable. The authors argue that field trials serve not just to gather evidence but also as strategic sites to implement and critically test RRI approaches, shaping the emerging innovation regime for carbon removal technologies.
Authors: Smith, HarrySynopsis: This thesis examines how national climate strategies address CDR in achieving net zero, focusing on Long-Term Low Emission Development Strategies (LT-LEDS). Analysis of 41–71 strategies shows reliance on nature-based CDR, concerns over reversal risks, and significant residual hard-to-abate emissions, especially in agriculture. A UK case study highlights demand for stronger government oversight, market stimulation, and standards governance. Overall, CDR is now central to climate policy, raising governance challenges and highlighting the need for targeted research on residual emissions, sectoral mitigation, and scaling CDR effectively.
Authors: Kyung-Min Noh, Xiao Liu, Charles Stock, Dennis McGillicuddy Jr. et al.Synopsis: Large-scale ocean iron fertilization (OIF) offers only a limited contribution to CDR. Century-scale fertilization in the Southern Ocean adds ~30 PgC (~0.3 PgC/yr), but effects elsewhere are largely offset by nutrient redistribution. After 30 years, ~50% of carbon remains locally; global retention is much lower. OIF-induced CDR is constrained by nutrient limitations, carbon-phosphorus ratios, and biogeochemical feedbacks, making actual global CDR 2–7× lower than idealized estimates. Standardized multi-model analyses are needed to better quantify its potential.
Authors: Teresa Maria Morganti, Wanxuan Yao, Nadine Mengis, Andreas Oschlies and Gregor RehderSynopsis: mCDR could remove 1–15 Gt CO₂ yr⁻¹—enough to meet mid-century climate targets—but currently contributes minimally to global CDR. A systematic review of mCDR monitoring methods reveals major challenges: linking observed chemical and biological changes to actual CO₂ removal, and accounting for heterogeneous marine processes and signal propagation. There is a critical need for standardized, reliable indicators and baselines to quantify carbon removal and environmental impacts. Without them, verification and integration into carbon markets remain limited, constraining mCDR’s long-term growth.
Authors: Elena Tajuelo Rodriguez, Lawrence M. Anovitz, Sai Adapa, Ke Yuan, Dale Hensley, et al.Synopsis: MgO shows promise as a sorbent for direct air capture of CO₂ under ambient conditions. Experiments with nano-scale MgO powders demonstrate that carbonation efficiency is higher for larger surface areas and does not decrease over repeated cycles. Instead, cycling can increase surface area due to hydration-induced particle fracturing forming brucite (Mg(OH)₂). Both amorphous and crystalline hydrated carbonates (nesquehonite, MgCO₃·3H₂O) form during carbonation. These results indicate MgO is durable and effective for CO₂ capture in humid, ambient conditions, making it a strong candidate for DAC applications.
Authors: Hans-Peter Schmidt, Samuel Abiven, Annette Cowie, Bruno Glaser, Stephen Joseph, et al.Synopsis: Biochar is a durable nature-based CDR strategy, with soil residence times typically exceeding 1,000 years and co-benefits for soil health. Its persistence depends on material properties (e.g., polyaromatic structure) and environmental factors (soil minerals, biology, climate). Biochar undergoes aging via decomposition and stabilization, including mineral interactions and soil aggregation. Unlike inertinite coal, biochar is not fully inert—small but measurable mineralization occurs over time. Policy frameworks should define biochar CDR over climate-relevant timescales (centuries), using traceable material data, conservative modeling, and ongoing field validation.
Authors: Muri, Helene, Sulpis, Olivier. Argüello, Gabriela. Baker, Chelsey, Böttcher, Miranda6, García-Ibáñez, Maribel et al.Synopsis: The European Marine Board Future Science Brief No. 13 outlines the challenges of monitoring, reporting, and verification (MRV) for marine carbon dioxide removal. Current mCDR methods lack robust, comprehensive MRV needed for credible large-scale deployment. The brief reviews existing observing systems, models, protocols, and governance, and provides recommendations for policymakers, funders, and practitioners to close knowledge gaps and develop standardized MRV frameworks before scaling up mCDR projects.
Authors: Md Basit Raza, Saheed Garnaik, Amit Kumar Dash, Arkaprava Roy, Priyanka Meena, Soura Shuvra Gupta, Tanmaya Kumar Bhoi & Debasis GoluiSynopsis: This chapter examines strategies for managing agricultural waste to reduce greenhouse gas emissions and enhance soil carbon sequestration. Approaches include composting, anaerobic digestion, biochar application, agroforestry, and improved agronomic practices. By integrating these methods into a circular bioeconomy, agriculture can improve soil health, sequester carbon, mitigate pollution, and generate carbon credits. Sustainable practices, technology, and supportive policies are key to transforming Indian agriculture into a net-negative carbon sink.
Authors: Namrata Kashyap, Vivek Yadav, Lalita Kumar Mohanty, Narinder Panotra, et al.Synopsis: This review examines soil carbon sequestration as a climate mitigation strategy, highlighting practices like conservation agriculture, cover cropping, biochar, agroforestry, and enhanced weathering. Optimized practices can sequester 0.4–1.2 Mg C ha⁻¹ yr⁻¹, but permanence, measurement, and socioeconomic challenges persist. Advances in monitoring, carbon markets, and policy incentives support adoption. The study underscores integrated landscape management, precision agriculture, and nature-based solutions as key for realizing soils’ full carbon sink potential.
Authors: Shambhunath Ghosh, Vikas Patidar, Anusmita Saha, Hemant Kumar Mina & Sandeep KumarSynopsis: Accurate measurement and verification of agricultural carbon credits are vital for credible carbon markets. While diverse soils, climates, and practices complicate accounting, technologies like remote sensing, machine learning, and blockchain improve accuracy, scalability, and transparency. Equitable frameworks, technical support, and policy guidance are needed to include smallholders and uphold integrity. Combining innovation with inclusive engagement ensures effective carbon markets that advance climate action and sustainable development.
Authors: Xing Zhou, Annalisa Bracco, Takamitsu Ito, Chris ReinhardSynopsis: This study uses a high-resolution coupled model to assess river-based carbon dioxide removal via alkalinity enhancement (AE) and enhanced weathering (EW) in the northern Gulf of Mexico. AE achieved 58–85% oceanic CO₂ uptake, higher with modest summer additions, while EW saw 12–15% re-emitted to the atmosphere, relatively stable across scenarios. Results indicate that long-term carbon removal efficiency depends on the ratio of alkalinity to dissolved inorganic carbon delivered to the coastal ocean.
Authors: Ruoqing Wang, Wei HeSynopsis: This study presents a synergy mapping framework for bipolar membrane electrodialysis (BMED) carbon dioxide removal, identifying where it can co-learn and co-scale with mature electrochemical systems versus areas needing bespoke innovation. Combining top-down cost targets and bottom-up technical estimates, the analysis shows BMED could achieve commercial readiness by 2050 at 25–100 % market share, but early-stage bottlenecks exist. Leveraging shared manufacturing and targeted research is critical to reduce costs and advance technical maturity.
Authors: Micheli D.P. Costa, I. Noyan Yilmaz, Pawel Waryszak, Rory Crofts, et al.Synopsis: This co-designed study of the Bidakarra estuary mangroves in Queensland demonstrates how Indigenous leadership, science, and local partnerships can advance ecological and cultural outcomes. The forest stores ~120,000 t C to 1 m depth, mainly in sediments, accumulating 1.84 t C ha⁻¹ yr⁻¹. Integrating Traditional Knowledge into blue carbon assessment highlights governance models that align climate, biodiversity, and cultural priorities, offering a replicable framework for equitable, community-led coastal management.
Authors: Pierre Friedlingstein, Corinne Le Quéré, Michael O’SullivanSynopsis: Despite the Paris Agreement, CO₂ emissions continue to rise, reaching 423 ppm in 2024 and 1.36 °C warming. Updated carbon budget analyses show the natural land sink is smaller than thought, anthropogenic land-use emissions are higher, and the ocean sink is 15 % larger than the land sink. Climate change reduces sink efficiency, turning parts of Southeast Asian and South American forests from sinks to sources. Accurate source–sink assessments are essential for effective climate policy and halting deforestation.
Authors: Pierre Friedlingstein, Michael O’Sullivan, Matthew W. Jones, et al.Synopsis: This update presents the 2024 global carbon budget, detailing fossil CO₂ emissions (10.3 ± 0.5 GtC), land-use emissions (1.3 ± 0.7 GtC), and total anthropogenic emissions (11.6 ± 0.9 GtC). Atmospheric CO₂ grew by 7.9 ± 0.2 GtC, reaching 422.8 ppm. Ocean and land sinks absorbed 3.4 ± 0.4 GtC and 1.9 ± 1.1 GtC, leaving a budget imbalance of −1.7 GtC. Preliminary 2025 data indicate continued emission growth and CO₂ rise to 425.7 ppm. Persistent uncertainties remain in land-use fluxes, northern land sinks, and mean ocean uptake, highlighting the need for continued monitoring and methodological refinement.
Authors: Michaela Sten, Kana Yamamoto, Timothy DeVries, Sebastian Krause, David A SiegelSynopsis: This study models seaweed-based marine carbon dioxide removal, showing that rapid sinking of seaweed biomass to deep waters (≥2,000 m at ≥1,000 m d⁻¹) can sequester CO₂ efficiently and durably (>100 years), comparable to direct air capture. Efficiency and longevity decline at slower sinking speeds or shallower sites. Outcomes depend on local vertical mixing, global circulation, and air-sea CO₂ exchange, highlighting the importance of site selection, conveyance strategy, and biomass fate for effective seaweed mCDR.
Authors: Redgwell, CSynopsis: This article examines how UNCLOS addresses emerging marine technologies, focusing on marine geoengineering. It highlights regulation under the global dumping regime and its Protocol, showing that responding to technological and environmental challenges is integral to UNCLOS. The study underscores UNCLOS’s continued role as the foundational framework for governing and managing new maritime technologies in the context of climate intervention and ocean stewardship.

“The PhD student will work on a project funded by the Swedish Research Council (VR) designed to quantify the net carbon sequestration capacity of seagrasses. Protecting and restoring seagrasses can enhance atmospheric CO2 uptake and thus mitigate climate change. Previous research has mainly focused on carbon stored in biomass and sediments, but much less is known about the export and long-term fate of dissolved organic and inorganic carbon produced by these ecosystems. Seagrasses generate carbonate alkalinity, a form of inorganic carbon, which remains permanently dissolved in seawater and buffers coastal waters against acidification.”
“This project will focus around a multi-year field trial of ERW at Newcastle University’s Cockle Park Farm, a working commercial farm that is used for a wide range of research into agricultural systems and has extensive state-of-the-art facilities including laboratory spaces and an integrated network of sensors for gathering environmental and climate data (see https://www.ncl.ac.uk/farms/virtual-tours/). Th PhD will take advantage of 9 replicated Hydrologically Isolated Plots (HIPs) with drainage that allows infiltrated water and surface run-off water to flow out separately through pipes that can be automatically sampled in response to discharge. This allows detailed measurements of solution chemistry to be made at regular intervals across rainfall events, and compared between plots that have had different treatments applied to them. In addition to water sampling, the HIPs ERW project is equipped with static chambers that can be deployed to measure fluxes of CO2, CH4, N2O and other significant gases from soil.”

Cracking the Code on Permanent Carbon Removal | Leaders on a Mission | Cracking the Code on Permanent Carbon Removal Leaders on a Mission 44:34 |
“What if we could remove CO₂ from the atmosphere today—and keep it gone for 1,000 years? In this episode, I’m joined by Barclay Rogers, founder and CEO of Graphyte, who is pioneering a breakthrough method called Carbon Casting that uses biomass by-products and low-energy engineering to lock away carbon at a fraction of the typical cost. We explore why many emissions cannot be abated, how durable removals differ from nature-based fixes, and what it takes to make carbon removal bankable and scalable. Remarkably, Graphyte went from founding to full-scale operation in just 18 months—proving that durable carbon removal can be delivered today, not decades from now.”
Diego Justiniano on Scaling Carbon Removal from the Heart of Bolivia | The Earthshot Podcast | Diego Justiniano on Scaling Carbon Removal from the Heart of Bolivia The Earthshot Podcast 35:02 |
“In this episode, Troy Carter speaks with Diego Justiniano, CEO of Exomad Green, about how Bolivia is building one of the most ambitious climate operations on the planet — and what it means for a nation to lead from its forests, not its factories.Exomad Green transforms what was once forest waste into biochar — a stable form of carbon that locks CO₂ away for centuries while restoring soil health. But this conversation isn’t just about biochar. It’s about the rise of a new kind of industry — one that’s circular, restorative, and deeply local.Troy and Diego discuss:- How Exomad Green built one of the world’s largest carbon removal operations- Why Bolivia’s forests can anchor a new era of regenerative industry- The challenges of scaling climate infrastructure in the Global South- What partnership and trust really mean in high-integrity carbon markets- How climate action can create jobs, dignity, and resilience — not just offsetsThis is a story about transformation - where industrial power meets ecological wisdom.From the heart of South America, Diego offers a vision of what a truly regenerative economy could look like when it begins with community, courage, and the forest itself.”
Unlocking the Ocean Sink: Permitting and Deployment of Marine Carbon Dioxide Removal Technologies | SPRingBoard Environmental Law Podcast | Unlocking the Ocean Sink: Permitting and Deployment of Marine Carbon Dioxide Removal Technologies SPRingBoard Environmental Law Podcast 58:34 |
“In the latest episode of the SPRingBoard Environmental Law Podcast, host Michael Hannaman explores one of the most promising and complex frontiers in climate innovation: Marine Carbon Dioxide Removal (mCDR).As global emissions continue to rise and the path to limiting warming to 1.5°C narrows, mCDR technologies are emerging as a key mitigation tool. These technologies leverage the ocean’s natural carbon cycle to capture and store CO₂, but questions remain about paths forward to large-scale deployment.To unpack this topic, Michael is joined by Garrett Boudinot (founder and CEO of Vycarb) and Meg Holden (principal at SPR). Together, they examine the science, economics, and legal frameworks underpinning the mCDR field and discuss the social and environmental considerations that guide deployment. What are the key factors for evaluating whether mCDR technologies can truly deliver durable climate benefits? What do early pilot projects reveal about technical feasibility and regulatory hurdles? And as the field matures, how can innovators and policymakers work together to streamline permitting, build public trust, and maximize impact?”

Unexpected Outgassing of C02 in Southern Ocean means Carbon Sink is LESS than we Thought | Paul Beckwith “The Southern Ocean carbon sink is massive. About half of human caused CO2 emissions are absorbed into the oceans, the majority in the very cold Southern Oceans near Antarctica.Southern Oceans and Antarctica are very desolate, especially in the 24/7 darkness of the southern hemisphere winter. Thus, data on absorption of CO2 into the water is very sparse and incomplete.In this new peer-reviewed paper, the new techniques using satellite based LIDAR (like radar, but with light) allows accurate measurements of the carbon sink in the Southern Oceans, even in winter.Data collected over the last few decades comes to the inescapable and surprising conclusion that CO2 outgassing in some regions is actually 40% higher than we thought, meaning that the southern ocean sink is not as powerful as we previously thought.”

SoilC4C – SoilCarbon4Climate Conference DAY 1 | 4p1000 Initiative “Increasing the soil organic carbon content has a large impact on climate change mitigation. Therefore, many countries count on soil organic carbon (SOC) sequestration as a land based solution, which will help them fulfil their climate targets, while increasing soil fertility and water retention. By fostering SOC sequestration and storage, agriculture can play an important role for climate change mitigation and adaptation, while ensuring food security. The last decade has seen vibrant dynamics in the field, including further scientific insights on SOC enhancing agricultural practices, improved monitoring, reporting and verification (MRV) tools, farmer movements for regenerative agriculture, new legislation around soil health, as well as the integration of carbon farming in carbon markets, just to name a few. During this time, the international “4 per 1000” Initiative has been a major advocate for healthy and carbon rich soils, aiming to foster multi-stakeholder collaboration and knowledge sharing.”
