THIS WEEK’S TOP CDR HIGHLIGHTS
SWISS CLIMATE PROTECTION ORDINANCE CONSULTATION
Switzerland plans a gradual scale-up of carbon removal to help the federal administration reach net-zero emissions by 2040, alongside steep emission cuts. Removals will be sourced via certified credits under the Swiss CO₂ Act, with the environment office as sole buyer. A consultation on the rules runs until 12 Feb 2026, with implementation expected from Sept 2026.
Avnos has secured up to $17 million in project financing from Shell US Gas and Power, LLC (Shell) and Mitsubishi Corporation (Americas), announcing a finalized decision to construct a first-of-its-kind hybrid direct air capture (HDAC) facility called Project Cedar.
Carbon to Sea and the Prince Albert II of Monaco Foundation are seeking research proposals to assess how ocean alkalinity enhancement affects commercially and culturally important marine species. The partners plan to fund two 24-month projects of up to $300,000 each. Applications close 16 January 2026, supporting safer, informed OAE deployment as field trials expand.
Remove has selected 16 startups for Cohort 8 of its Europe CDR Accelerator Program after a three-month open call. The new cohort will receive training, coaching, networking and non-dilutive funding to scale carbon removal solutions. Selected companies include carbondrop™, Pure Hawa, reilo, Restord, BioBright, ReStore Carbon, Alpine X, fortyfour, Reaforma, Circular Carbon Pathways, Carbony, CO₂Zero, Carbonway, KORALL, Exothermite, and Lightnet Carbon Capture.
According to a new report by CDR.fyi, the durable CDR market reached 8.5 Mt contracted in Q3 2025, up 54% from Q2 and already surpassing 2024 totals. However, 93% of volume came from two Microsoft megadeals, with only 604 kt purchased by 67 other buyers. Biomass-based pathways dominated. Despite record contracts, delivery and buyer diversification remain weak signals for the sector’s strength.
The Science Based Targets initiative (SBTi) released a revised 97-page draft of its Corporate Net-Zero Standard V2.0, offering companies more flexibility on targets while tightening ongoing emissions rules. The draft allows feedback until Dec 8, with the final version published in 2026 and mandatory adoption of its rules starting in 2028.
CSIRO Futures and CarbonLock released the Australian Carbon Dioxide Removal Roadmap, finding Australia could remove up to 330 Mt CO₂/year by 2050. It highlights opportunities to scale CDR, support net zero, and engage in global carbon markets.

RESEARCH PAPERS
Cropland Enhanced Weathering in Low GDP Regions for Gigaton Scale Carbon Removal with Potential Economic Co-benefits
Authors: Bingzheng Wang and Fengqi You
Synopsis: Enhanced rock weathering on croplands can remove CO₂ and support equitable decarbonization. Low-GDP regions hold 55–89% of national ERW potential, and deploying ERW on 10% of cropland could remove ~22.9 Gt CO₂ by 2075. Carbon trading with wealthier regions could yield economic gains up to 4.5% of local GDP. This approach aligns with COP29 goals, enabling regions to contribute to climate mitigation according to their strengths.
Turning Biosolids into Carbon Storage: Scaling Subsurface Injection at the TIRE Facility to Meet Los Angeles’ 2050 Population-Driven Emission Demands
Authors: A. M. Hassan; I. Mohamed; O. Sameh; M. Fawzy; Y. Panchal; A. Amirlatifi; O. Abou-Sayed; A. Abou-Saye
Synopsis: This study evaluates using subsurface Biosolid Slurry Injection (BSI) at Los Angeles’s TIRE facility to offset CO₂ emissions from population growth. Population-driven biosolid generation strongly correlates with CDR potential (R² = 0.96). Current operations sequester ~0.3 Mt CO₂e/yr per well; scaling to seven wells could achieve ~154,000 Mt CO₂e/yr. The analysis provides a city-scale roadmap linking municipal biosolid management with scalable carbon removal, offering a transferable strategy for growing urban centers pursuing net-zero targets.
Alive and dead earthworms capture carbon during mineral weathering through different pathways
Authors: Tullia Calogiuri, Mathilde Hagens, Jan Willem Van Groenigen, Florian Wichern, et al.
Synopsis: Enhanced rock weathering captures atmospheric CO₂ and may stabilize soil organic carbon, with earthworms playing a key role. Using stable isotope tracing, the study shows that live earthworms promote organo-mineral associations via dejections, enhancing organic carbon persistence, while dead earthworms boost microbial activity, increasing inorganic carbon capture. Earthworms thus influence carbon cycling across their life cycle through distinct biological and physico-chemical pathways.
Natural carbon uptake by ocean biology will not deliver credible carbon credits - Comment
Authors: Lennart T. Bach, Phil Williamson, Joanna I. House & Philip W. Boyd
Synopsis: Claims that natural CO₂ removal constitutes anthropogenic climate mitigation are increasingly misleading. While this misrepresentation is common for forests and coastal ecosystems, similar errors may arise regarding open-ocean CO₂ uptake through the biological carbon pump, risking overestimation of human-driven mitigation efforts.
Pyrogenic carbon contribution to tropical savanna soil carbon storage
Authors: Yong Zhou, A. Tyler Karp, Abigail Schmidt & Corli Coetsee
Synopsis: In Kruger National Park savannas, fire-derived pyrogenic carbon (PyC) contributes ~14% of surface soil organic carbon, reaching up to 40%. PyC accumulation is influenced by fire frequency, grass biomass, clay content, and low rainfall, which favor preservation. These findings highlight PyC’s significant role in savanna carbon storage and provide insight into environmental factors controlling fire-driven contributions to the soil carbon cycle.
Spaces of anthropogenic CO2 emissions compatible with climate boundaries
Authors: Thomas Bossy, Philippe Ciais, Katsumasa Tanaka, Franck Lecocq, Philippe Bousquet & Thomas Gasser
Synopsis: Climate boundaries define safe limits for global warming, ocean acidification, sea-level rise, and Arctic ice loss. In this study, a reduced-form model maps CO₂ emissions, removal, and solar radiation management (SRM) pathways to remain within these limits. With emissions peaking in 2030, net-zero by 2050, and 10 PgC yr⁻¹ removal, the chance of staying below 2 °C is 80%, but drops to 35% when all four boundaries are combined. Results underscore trade-offs and the need for holistic climate strategies.
Empirical analysis of project–purchaser dynamics in Japan’s blue carbon dioxide removal credit scheme - Preprint
Authors: Tomohiro Kuwae, Yuka Suzuki, Masanori Furuya
Synopsis: Analysis of 61 blue carbon projects and 471 J-Blue Credit transactions in Japan shows that projects averaged 3.2 co-creators, with small-volume but high-value credits (~400 USD/tCO₂). About 40% of trades were local, with hard-to-abate sectors and companies with decarbonization policies driving demand. Project co-benefits influenced purchaser numbers and prices, while sector and location preferences shaped market outcomes. Results highlight the role of collaboration, project appeal, and sector-specific demand in scaling carbon credit markets and nature-based CDR.
Global Collaboration in Carbon Dioxide Removal: Navigating a Fragmented Landscape
Authors: Romain Presty, Olivier Massol & Pascal Da Costa
Synopsis: A bibliometric review of 9,280 CDR publications (2015–2024) from 151 countries reveals a fragmented research landscape dominated by the EU27, US, and China. Collaborations are often nationally or thematically clustered, with few institutions bridging regions. This structural fragmentation may limit shared methodologies and coordinated policy support. Strengthening international partnerships, harmonizing standards, and aligning science with policy are key to advancing global CDR research.
Machine learning–enabled optimization of a direct air capture system integrated with enhanced oil recovery
Authors: Farzin Hosseinifard, Shahabeddin Ghasemzadeh, Mohsen Salimi, Majid Amidpour
Synopsis: This study presents a novel DAC system integrated with enhanced oil recovery (EOR), modeled via Aspen Plus using a hydroxide-to-carbonate CO₂ absorption pathway. Machine learning, including XGBoost, Random Forest, and Decision Trees, assessed DAC’s impact on EOR in Abadan. The Decision Tree model performed best (R² = 0.87), predicting an increase in EOR efficiency from 19 % to 21.3 %, demonstrating DAC’s potential to enhance carbon management and oil recovery simultaneously.
Artificial intelligence for carbon sequestration: A multi-scale review of nature-based and engineered pathways
Authors: Jianhua Ma, Yongzhang Zhou, Luhao He, Palate Kenjiebo, Yijun Zheng, Xian Liu
Synopsis: Achieving carbon neutrality drives both nature-based (forests, soils, oceans) and engineered (CCUS, DAC, enhanced weathering) sequestration, but modeling challenges persist due to system complexity and heterogeneity. This review introduces a “task-data-algorithm” framework for model selection and benchmarking. AI methods like CNNs and RFs enhance mapping, prediction, and optimization. The framework aids intelligent carbon system design and informs policy for deploying effective low-carbon strategies.
Aboveground biomass in Australian tropical forests now a net carbon source
Authors: Hannah Carle, David Bauman, Michael N. Evans, Ingrid Coughlin, et al.
Synopsis: Long-term data from Australian moist tropical forests reveal a shift in aboveground woody biomass from a carbon sink (0.62 Mg C ha⁻¹ yr⁻¹, 1971–2000) to a carbon source (−0.93 Mg C ha⁻¹ yr⁻¹, 2010–2019). Rising temperatures and climate anomalies increased tree mortality, with no detectable CO₂ fertilization effect. Cyclones further punctuated biomass losses. These results suggest that global moist tropical forests may face a long-term transition from carbon sinks to sources under climate change.
Comparative Analysis of Carbon Sequestration Potential of Agroforestry Systems in Habro District, Eastern Ethiopia
Authors: Yosef Fantaye
Synopsis: In Habro District, Ethiopia, coffee-based agroforestry systems outperform parkland systems in carbon sequestration. Coffee-based systems store 33.94 Mg C ha⁻¹ in biomass and 158.1 Mg C ha⁻¹ in soil, totaling 192.64 Mg C ha⁻¹ versus 124.72 Mg C ha⁻¹ in parkland. Enhanced tree cover, litter input, and low soil disturbance drive these gains. The study highlights agroforestry as a nature-based solution supporting climate mitigation, livelihoods, and integration into carbon finance and national strategies like Ethiopia’s NDCs, REDD+, and AFR100.
Illuminate underground phenology to aid carbon sequestration - Comment
Authors: Tengteng Li, Nico Eisenhauer & Zhanfeng Liu
Synopsis: Climate change is altering the seasonal rhythms of soil organisms that regulate plant carbon transformation and storage. Maintaining temporal coordination between above- and belowground biota is essential for sustaining resilient soil carbon sinks under warming conditions.
Biochar-driven soil carbon sequestration: priming effects and emission reduction
Authors : Wei Han,a Yujian Laia and Hongbing Ji
Synopsis: Biochar, a carbon-rich product of biomass pyrolysis, can enhance soil carbon sequestration and reduce CO₂ emissions, but its effects on soil carbon cycling are complex. Priming effects may promote or inhibit mineralization, and laboratory studies may underestimate oxidation risks in natural conditions. Key stabilization mechanisms include physical protection, chemical stability, and microbial transformations. Future research should clarify molecular carbon dynamics and tailor biochar application to field and soil conditions for optimized carbon removal.
The Spatial Distribution of Soil Inorganic Carbon in the Contiguous United States - Preprint
Authors: Zahra Ghahremani, David P Huber, Arash Modaresi Rad, Michael J Johnson, Jennifer Pierce
Synopsis: This study presents a high-resolution (30 m) soil inorganic carbon (SIC) map of CONUS using machine learning and Google Earth Engine. CONUS soils store ~77 ± 1.8 Pg SIC in the top 1 m, exceeding prior estimates. SIC occurs as lithogenic carbonates in humid regions and pedogenic carbonates in arid soils. Soil pH strongly predicts calcareous formation, while precipitation above 1700 mm/year limits pedogenic carbonate accumulation. The map improves predictions and reduces uncertainty in unsampled areas.
Understanding soil carbon sequestration: mechanistic insights, management approaches, and future challenges
Authors: Vivek Ghimirey, Jay Chaurasia & Nobel Acharya
Synopsis: Soil carbon sequestration (SCS) captures atmospheric CO₂ in soils as organic or mineral carbon, offering climate mitigation and co-benefits like improved fertility, water retention, and biodiversity. From 2000–2025, SCS methods—including reduced tillage, cover crops, agroforestry, biochar, and wetland restoration—have shown promise but face challenges in quantification, climate variability, costs, and policy support. Standardized monitoring, carbon markets, and research on microbial and long-term stabilization mechanisms are needed to scale SCS globally.
Is soil sampling appropriate for quantitative carbon accounting for biochar? An experimental investigation to assess soil carbon accumulation
Authors: David Chiaramonti, Giulia Lotti, Francesca Tozzi, David Casini, Francesco Primo Vaccari, Hamed Sanei, Michaela Luconi, Marco Buffi
Synopsis: Biochar is a key CDR method with agricultural co-benefits, yet conventional soil sampling protocols inadequately quantify its carbon savings. Experiments show that spatial heterogeneity, limited sample size, and blending challenges cause SOC measurements to misrepresent actual carbon added. These limitations raise concerns for other carbon farming approaches. Robust GHG accounting requires combining careful experimental design with validated modeling frameworks to ensure defensible carbon credits and mitigation claims.
Nutrient-Rich Mineral-Associated Organic Matter Limits Carbon Storage Under Elevated Carbon Dioxide in a Low Phosphorus Eucalyptus Woodland Soil
Authors: Anna Favaro, Yolima Carrillo, Balwant Singh, Charles Warren, Feike A Dijkstra
Synopsis: Twelve years of elevated CO₂ (eCO₂) in a low-phosphorus Eucalyptus woodland reduced mineral-associated organic matter (MAOM) C, N, and P by 15–16%, while particulate organic matter (POM) remained unaffected. The decline in MAOM is linked to rhizosphere priming, where microbes mined nutrient-rich MAOM to meet phosphorus demand, limiting soil carbon accumulation under eCO₂. These findings highlight the vulnerability of MAOM in low-P soils and its role in constraining carbon sequestration.
Alkalinity enhancement with sodium hydroxide in coastal ocean waters - Preprint
Authors: Cathryn A. Wynn-Edwards, Wayne Dillon, John Akl Uhril, Craig Neill, et al.
Synopsis: The first Australian field trial of Ocean Alkalinity Enhancement (OAE) used continuous NaOH addition to coastal Tasmanian waters. At the release point, pCO₂ dropped by ~370 µatm and alkalinity increased by ~545 µmol kg⁻¹, with downstream pCO₂ decreases of 22–77 µatm (<1–5% signal). The trial showed rapid plume dispersion measurable in situ, demonstrating that shore-based OAE combined with local infrastructure and modeling holds potential as a scalable marine carbon dioxide removal strategy.
