TABLE OF CONTENTSNote: Click on the headings listed in the table of contents above to easily navigate to the sections you're interested in. THIS WEEK’S TOP CDR HIGHLIGHTSCDR FUNDING BOOST: Germany’s 2026 draft budget allocated nearly €500 million for carbon dioxide removal (CDR), including €111 million in 2026 and €320 million planned through 2033, starting with €90 million in 2027. €45 million is earmarked for soil carbon in 2026. The Environment Ministry has also created a dedicated department for negative emissions within its National Climate Policy division. RESEARCH PAPER: Forests cover 40% of the EU land and have helped absorb about 10% of its carbon emissions since 1990 to 2022. But a new Nature study warns their sink capacity is falling fast, down 27% in a decade. Annual absorption dropped from 457 MtCO₂e (2010–14) to 332 MtCO₂e (2020–22), putting the EU’s 2050 climate-neutral target and 2030 sink goals at serious risk. JAPAN CDR COUNCIL: Mitsubishi Research Institute and Mitsubishi Corporation have announced plans to launch the Japan CDR Council. The initiative aims to unite diverse stakeholders to accelerate CDR development and build a robust carbon removal ecosystem in Japan. AIRMINERS BUYERS CLUB: AirMiners has opened its 2025 Buyers Club supplier application, seeking carbon removal credits of 100–10,000 t with 12–18 month delivery timelines. Biochar, BECCS, biomass burial, BiCRS and nature‑based methods preferred. Deadline: 08 August 2025 DOCUMENTARY: A recent documentary by NZZ Format showcases Swiss organizations like Climeworks and Neustark, along with innovators such as Carbfix and a local biochar producer in the Swiss Alps. It explores whether carbon removal technologies can realistically support climate goals. With global capacity at just 1 Mt, the film questions whether scaling, funding, and policy efforts are sufficient to reach the billions of tons needed by 2050. FUNDING OPPORTUNITY: Pinwheel opened a new funding round for nature-based and durable CDR projects. Apply by 05 September 2025 Read on to unpack more updates: COMMERCIAL NEWS Share Carbon Removal Updates RESEARCH PAPERSAuthors: Lucilla Boito, Laura Steinwidder, Jet Rijnders, Jesse Berwouts, Sarah Janse, Harun Niron, et al.Synopsis: This 15-month mesocosm study on enhanced weathering (EW) with basalt reveals complex effects on soil CO₂ efflux (SCE), influenced by plants, earthworms, and soil moisture. Basalt increased rhizosphere respiration initially but later reduced SCE in unplanted soils. Results highlight the need to consider both biotic and abiotic factors in EW assessments and to account for soil organic carbon dynamics when evaluating EW’s climate mitigation potential.
Authors: William F. Lamb, Sean Low, Leo-Michael Gordon, Maisa MattilaSynopsis: This analysis of 2024 reports from OGCI oil and gas firms questions their commitment to scaling CDR. While firms cite net-zero goals, CDR plans are vague, anecdotal, and tied to ESG narratives. Nature-based solutions dominate, with limited focus on scalable options like DACCS. CDR may be used more as a hedge against policy than a decarbonization strategy. The study maps firm strategies and outlines possible future trajectories.
Authors: Csaba Tölgyesi, Nándor Csikós, Vicky M. Temperton, Elise Buisson, Fernando A. O. Silveira, et al.Synopsis: This study estimates global carbon sequestration from restoring forests, shrublands, grasslands, and wetlands by 2100 at up to 96.9 Gt, just 3.7–12% of projected emissions. Accounting for climate-driven ecosystem changes, mitigation potential nears zero. Thus, ecosystem restoration should prioritize biodiversity, livelihoods, and resilience, with limited reliance on it as a climate solution.
Authors: Navneet Goswami, Shraavya Rao, Sergio Diaz Abad, Andrew Ruba, Harshul Thakkar, et al.Synopsis: This study presents a multiscale modeling framework for DAC using carbon nanofiber (CNF) sorbents. By combining pore-scale LBM and macroscale modeling, it shows that a balanced micropore–mesopore structure enhances CO₂ adsorption. Hierarchical porosity improves site use and reduces transport losses. These findings offer design insights for more efficient, durable, and low-energy DAC systems.
Authors: Farzin Hosseinifard, Mohsen Salimi, Majid AmidpourSynopsis: This study evaluates four solar-assisted DAC system designs using techno-economic and exergoeconomic analysis. The PV + Single Solar Tower setup offers the lowest cost ($276.21/ton) and best cost-effectiveness, while PV + PTC shows highest exergy efficiency. Results suggest solar-integrated DAC, especially tower-based systems, can lower costs and improve performance, making them promising for large-scale CO₂ removal.
Authors: Fugo Nakamura, Hkaung Htut San, Hajime Iwaki, Monthicha Rawangphai, Naomi Kitagawa, et al.Synopsis: This study explores Enhanced Rock Weathering using basalt in acid mine drainage (AMD) sites. Modeling shows ERW can deliver net carbon removal and enable passive AMD treatment. Basalt boosts mineral weathering and schwertmannite formation, which adsorbs arsenic while maintaining acidity. Life cycle and economic analyses confirm feasibility, suggesting ERW could offset costly, carbon-intensive limestone treatment at arsenic-contaminated AMD sites.
Authors: Johannes Meyer zu Drewer, Maria-Elena Vorrath, Thorben Amann, Jens Hartmann, Jose Maria De la Rosa, et al.Synopsis: This study explores PyMiCCS, a combined CDR approach using co-pyrolyzed biomass and silicate rock powder to create rock-enhanced biochars. These composite materials offer higher nutrient content, liming effects, and C-sink potential. Co-pyrolysis boosts thermal stability but reduces porosity, with unclear impacts on weathering. The method shows promise for multifunctional CDR, though further research is needed on environmental persistence and weathering dynamics.
Authors: Katrina Kloesel, Vittoria Bolongaro, Paolo Gabrielli, Viola Becattini, Marco MazzottiSynopsis: This study introduces a simplified Earth system model to explore CO₂ management pathways to net-zero, focusing on CCS, BECCS, and direct air capture. It finds CO₂ reduction and removal equally impactful in today's net-positive world, but removal is essential for net-zero. Success hinges on sufficient CO₂ storage and full fossil fuel phase-out. The framework aims to guide better policy design, resource use, and public trust in climate solutions.
Authors: Ella Milliken, Alex Woodley, Noah J. PlanavskySynopsis: This study demonstrates continuous in-soil CO₂ monitoring in a basalt-amended soybean plot in Virginia, marking a first in agricultural enhanced weathering trials. Results show clear CO₂ flux reduction, equal to 1.04 tCO₂/ha/year, mostly during the growing season after rain. This validates EW as a scalable, durable carbon removal method and highlights the value of continuous gas-phase measurements for understanding EW dynamics.
Authors: Flore Verbist, Emma Jagu Schippers, Injy Johnstone, Coline Seralta, Romain Presty, Antigoni TheocharidouSynopsis: This review explores how CDR is being integrated into voluntary, quasi-compliance, and compliance carbon markets. While voluntary markets drive CDR innovation, lasting impact requires robust compliance frameworks. Emerging mechanisms like Article 6 and ETS are starting to include CDR, though permanent removals remain costly and underused. Hybrid policy models and stronger certification systems may enhance CDR’s role in carbon market systems.
Authors: Felix Dörpmund, Christoph Brändle, Antonia Holland-Cunz and Lukas TankSynopsis: This study examines how private actors—tech suppliers, buyers, and financiers, shape CDR governance. Based on 79 interviews, it reveals diverse views on regulation, transparency, funding, and climate justice. Key tensions include oil sector involvement and the trade-off between scaling fast and ensuring inclusive processes. The findings highlight the complex, influential role of private organizations in CDR's ethical and market frameworks.
Authors: Hanna FiegenbaumSynopsis: This paper critiques how timber use in construction is classified in carbon markets, warning that conflating storage with carbon removal may undermine market integrity. It evaluates classification methods and urges treating timber within broader building-level mitigation strategies. It also stresses robust attribution methods and the need to address biodiversity and land-use trade-offs in timber-based climate policies.
Authors: Sophie Chlela & Sandrine SelosseSynopsis: This review identifies key challenges in applying Life Cycle Assessment (LCA) to CDR, including inconsistent system boundaries and limited focus on permanence. It calls for broader use of consequential approaches, integration with system modeling, and standardized metrics like permanent CO₂ removed. Addressing these gaps is vital for assessing environmental trade-offs and guiding responsible large-scale CDR deployment.

Transforming Minerals with Biology: Rare Earth Extraction and Carbon Storage with Buz Barstow and Esteban Gazel | The Climate Biotech Podcast | Transforming Minerals with Biology: Rare Earth Extraction and Carbon Storage with Buz Barstow and Esteban Gazel The Climate Biotech Podcast 1:00:22 |
"Mining has essentially been the same for 5,000 years, just now with bigger shovels. Imagine if we could drastically increase mining efficiency and output for both the environment and national security. That's exactly what Dr. Esteban Gazel, a Costa Rican-born geochemist, and Dr. Buz Barstow, a physicist-turned-synthetic biologist, are working on at Cornell University.When these brilliant minds connected over rare earth elements and carbon storage, they realized that existing microorganisms could be engineered and optimized to transform how we extract critical minerals from the earth. Their groundbreaking research has already improved the microbe Gluconobacter's ability to extract rare earth elements by an astounding 1,200% compared to its natural capabilities. This biological approach operates at room temperature with minimal environmental impact, potentially transforming mining from a destructive industry into a sustainable process.The stakes couldn't be higher. Each wind turbine requires five tons of copper and one ton of rare earth elements, materials that currently demand processing hundreds or thousands of tons of rock through energy-intensive methods. As we transition to clean energy, these demands will only increase, creating an urgent need for sustainable extraction approaches.Their Microbe Mineral Atlas project aims to catalog how microorganisms interact with minerals, identifying biological systems that can dissolve rocks, generate acids, create chelators, and precipitate specific elements. Beyond metal extraction, they're exploring how microbes might accelerate natural carbon sequestration processes in minerals like olivine.What makes their work so powerful is their complementary expertise – Gozel's deep knowledge of mineral thermodynamics paired with Barstow's synthetic biology innovations. Their vision goes beyond incremental improvements; they're reimagining mining entirely with processes that can efficiently extract multiple elements simultaneously, utilize low-grade deposits, and operate with minimal environmental impact."
