ABSTRACT
This week’s Carbon Removal Updates captured significant movement across CDR funding, procurement, project deployment and research. Commercially, Google announced more than $6 million in 2026 R&D awards for CDR and superpollutant elimination; Carbon to Sea opened two OAE research calls worth up to $6 million; and VodafoneThree launched procurement for 24,000 tonnes of UK-based CDR.
New projects included Sequest’s 1,000-tonne Horizon facility in Saudi Arabia; CO2-Sync’s biochar facility in Utah targeting more than 2,000 tonnes of annual biochar output; Holcim and 44.01’s continuous cement-sector carbon capture and mineralization project in the UAE; and Valorify’s progress toward Asia-Pacific BECCS credits.
The week also brought contrasting commercial signals, with Chevron withdrawing from a proposed $500 million DAC project in California; Microsoft reportedly cutting carbon removal purchases by 80% amid its AI-driven capital and energy demands; and Indo-Danish CDR company MASH Makes filing for bankruptcy.
Research covered the environmental realism of ocean alkalinity enhancement experiments; Germany’s potential for approximately 110 MtCO₂ of annual bio-based CDR by 2050; delayed recovery of Arctic ocean acidification even under negative emissions; and a sharp weakening of the global land carbon sink during the 2023–24 El Niño.
Additional studies advanced electrochemical marine CO₂ removal, geological storage in mafic rocks, biochar-enhanced weathering, bioleaching for carbon mineralization, forest and soil carbon accounting, and strategies for addressing residual urban emissions.
The edition also highlights developments in CDR standards and market integrity, including approval of Isometric’s agroforestry protocol, alongside new funding opportunities, policy initiatives, events and 582+ job openings across the sector.

Lethal by Design? Resolving Differences Between Experimental and Real-World Alkalinity Perturbations in Ocean Alkalinity Enhancement
Authors: Lennart T. Bach, Michael D. Tyka, Bin Wang, Katja Fennel
Synopsis: Using dilution equations and regional and global ocean models, this study assesses the magnitude and duration of total alkalinity (ΔTA) changes that marine organisms could realistically experience under OAE. It finds that extreme perturbations above 1,000 μmol kg⁻¹, common in experiments, occur only briefly and across a very small fraction of affected seawater. In contrast, ΔTA of 1–100 μmol kg⁻¹ is widespread under realistic OAE conditions but is less studied. The findings highlight the need to better contextualize experimental ΔTA levels to avoid overstating environmental impacts.
Unleashing the combined potential of bio-based carbon dioxide removal in Germany’s path to net zero from the bioenergy system perspective
Authors: Mohammad Sadr, Danial Esmaeili Aliabadi, Matthias Jordan, Ronja Wollnik, Daniela Thrän
Synopsis: Using a comprehensive regional modeling approach, this study evaluates the cost-effective deployment of bio-based CDR across Germany to support its 2045 net-zero target and subsequent net-negative emissions. The analysis integrates techno-economic and regional conditions across energy and non-energy sectors, focusing on technical and natural carbon sinks within the BENOPTex model. Results show that co-deploying both sink types could increase overall CDR potential by at least 50% while reducing removal costs, reaching approximately 110 Mt CO₂ annually by 2050.
Persistence of Arctic Ocean acidification under negative emissions
Authors: Eike E. Köhn, Lester Kwiatkowski, Juliette Mignot, Guillaume Gastineau, Olivier Torres & James C. Orr
Synopsis: Examining how declining atmospheric CO₂ could affect ocean acidification, this study analyzes eight Earth system models under scenarios of rising and subsequently falling CO₂ concentrations. The Arctic emerges as a hotspot of delayed recovery, with surface waters remaining more acidic and aragonite-corrosive conditions persisting until atmospheric CO₂ falls about 120 ppm below the level at which acidification initially occurred. This hysteresis is linked to changes in dissolved inorganic carbon and sea-ice-mediated air–sea gas exchange, indicating that the Arctic may experience delayed benefits from negative emissions.
Assessing stand development controls on carbon sequestration and carbon credit value in tropical introduced teak plantation
Authors: John Oluwafemi Ayoola, Babatunde Oluseyi Ajiboye, Abraham Olanrewaju Opanike, Fahim Arshad, Shiekh Marifatul Haq, et al.
Synopsis: Evaluating the climate mitigation and economic potential of introduced teak plantations in Nigeria, this study examines changes in stand structure, biomass, carbon stocks, and carbon credit value across plantations aged 12 to 23 years. Older plantations showed larger tree dimensions, greater basal area and biomass, and higher aboveground carbon stocks, which increased from 30.21 to 47.47 Mg C ha⁻¹. Carbon sequestration potential rose from 158.90 to 236.42 Mg CO₂e ha⁻¹, while estimated carbon credit values increased from US$3,178 to US$4,752, highlighting the potential of teak plantations as carbon sinks.
A Compact Hollow Fiber Electrode Assembly Architecture for Continuous Electrochemical Marine Carbon Dioxide Removal
Authors: Inhwan Park, Young Hun Lee, Jung Hun Lee, Seung-Jeong Oh, T. Alan Hatton, Dong-Yeun Koh
Synopsis: Introducing a compact membrane-integrated hollow fiber electrode architecture, this study addresses key barriers to electrochemical direct ocean capture (e-DOC), including limited electrode interfaces, high Ohmic losses, complex reactor designs, and mineral fouling. The macroporous stainless-steel hollow fibers provide high electrochemically active surface area and mechanical durability, while the coaxial configuration reduces ionic transport distances and enables efficient hydroxide generation. The system achieves over 85% dissolved inorganic carbon removal and stable continuous operation for more than 100 hours, demonstrating potential for scalable ocean decarbonization.
Low latency global carbon budget reveals land sink decline during 2023 to 2024 El Niño
Authors: Piyu Ke, Philippe Ciais, Yitong Yao, Stephen Sitch, Wei Li, Yidi Xu, et al.
Synopsis: Highlighting the impact of El Niño droughts on the global carbon cycle, this study updates the low-latency global CO₂ budget through June 2024 using fossil-emission data, vegetation models, ocean carbon emulators, and atmospheric inversions. Atmospheric CO₂ growth reached 3.66 ± 0.09 ppm yr⁻¹, the highest July-to-July rate since 1979. The increase was primarily driven by a 2.24 GtC yr⁻¹ weakening of the land carbon sink, with 97.5% of the land anomaly occurring in the tropics.
Empirical insights into residual emissions in urban net-zero targets
Authors: Giulia Ulpiani, Quirina Rodriguez Mendez, Valeria Todeschi, Gema Hernandez Moral, Nadja Vetters, Marco Pittalis, Sabine Fuss, Christiaan Gevers Deynoot & Felix Creutzig
Synopsis: Assessing the residual emissions strategies of 103 European cities targeting net zero by 2030, this study finds that they collectively face 61.4 MtCO₂e of residual emissions, primarily from buildings and transport. All cities rely on temporary land-based carbon removal, while 40% use carbon credits and 32% permanent removals. A newly developed residual emissions strategy robustness index indicates medium-low maturity and significant geographic disparities. The study identifies gaps in land availability, urban carbon sinks, reversal safeguards, monitoring, timing, and emissions quantification, and proposes recommendations for improving city-level residual emissions strategies.
Electrochemically Driven Sorbent-Mediated Recovery of CO2 in Marine Inorganic Carbon Extraction Processes
Authors: Michael P. Nitzsche; Michael Massen-Hane; Annlin Su; Kripa K. Varanasi; T. Alan Hatton
Synopsis: Focusing on the energy- and capital-intensive CO₂ stripping stage of pH-swing marine carbon dioxide removal (mCDR), this study develops an alternative sorbent-mediated approach for concentrating CO₂ from seawater. The framework includes an electrochemically mediated implementation designed to avoid the indiscriminate removal of dissolved oxygen associated with vacuum stripping. Through experimental demonstration and comparative technoeconomic and energy assessments, the study finds that sorbent-mediated extraction could provide a viable alternative to existing vacuum-based processes.
Forest canopy decline under elevated CO2 during the Paleocene-Eocene Thermal Maximum
Authors: Regan E. Dunn, Marieke Dechesne, Brady Z. Foreman, Keifer Nace, Jenna M. West ll, and Ellen D. Currano
Synopsis: Using the Paleocene-Eocene Thermal Maximum (PETM) as an analog for rapid anthropogenic warming, this study reconstructs forest canopy density and vegetation composition in Wyoming approximately 56 million years ago. A new leaf area index proxy and palynomorph analysis reveal abrupt canopy opening, increased landscape erosion, and a shift from broad-leaved angiosperms toward fern- and palm-dominated ecosystems. Regional evidence suggests that large-scale vegetation changes can destabilize landscapes and potentially influence long-term hydrological and carbon-cycle feedbacks under rapid warming.
Feasible geological carbon dioxide storage projections require updated cost and geological potential assumptions
Authors: Iain de Jonge-Anderson, Gareth Johnson, Anne Merfort, Jessica Strefler, Catrin Harris & Jennifer J. Roberts
Synopsis: Assessing the feasibility of carbon dioxide geological storage in climate mitigation pathways, this study examines how six leading detailed-process Integrated Assessment Models (IAMs) represent deployment constraints. The models primarily rely on datasets covering annual storage rates, costs, and geological storage potential, with recent updates largely improving assumptions about annual deployment rates. However, cost and storage potential estimates remain based on outdated literature. The study calls for updated, IAM-ready datasets to strengthen confidence in geological storage projections and improve transparency around model assumptions.
Aboveground Carbon Stocks and Soil Carbon Pools in Sub-Mediterranean Ecosystems of the Black Sea Coast of Russia: A Descriptive Case Study of Two Contrasting Plots
Authors: Sergey N. Gorbov, Nikita V. Shevchenko, et al.
Synopsis: Providing an exploratory assessment of ecosystem carbon stocks on Russia’s northeastern Black Sea coast, this study compares aboveground biomass carbon in a terraced pine–oak plantation and a natural pubescent-oak shiblyak. The plantation stored substantially more aboveground carbon (64.1 t C ha⁻¹) than the natural community (16.1 t C ha⁻¹), with woody biomass dominating the plantation and litter and herbaceous vegetation contributing more in the shiblyak. Combined with previously reported soil carbon data, the findings establish a baseline for future spatially replicated studies of sub-Mediterranean ecosystem carbon dynamics.
Carbon dioxide storage in mafic reservoir rocks in Sweden: Controls on dissolution and carbonation during early water-rock interaction
Authors: Emelie Crafoord, Ayanne de Oliveira Maciel, Christina Wanhainen, Paul Christakopoulos, Ulrika Rova, Glenn Bark, Io Antonopoulou
Synopsis: Focusing on mafic rocks from potential Swedish subsurface CO₂ storage reservoirs, this study evaluates their early-stage dissolution and carbon mineralization potential. Batch experiments show that dolerite releases the most elements, followed by gabbro and metabasalt, with dissolution controlled by different reactive mineral phases. Carbonation experiments confirm the formation of secondary carbon-bearing phases, including Mg-, Fe-, and Ca-carbonates. The findings indicate favorable mineralization potential, while emphasizing that mineral reactivity, alteration, fracture networks, permeability, and subsurface conditions will determine successful CO₂ storage.
The hydrogen puzzle in rock-enhanced biochar: Pyrogenic coating, mineral redox and pore accessibility
Authors: Johannes Meyer zu Drewer, Tobias Bromm, Thomas D. Bucheli, Pellegrino Conte, José María de la Rosa, Harald Fitzek, et al.
Synopsis: Investigating rock-enhanced biochars as a combined carbon dioxide removal approach, this study examines how co-pyrolyzing basanite rock powder with wood affects biochar properties and mineral chemistry. Six RE-biochars with varying rock contents were produced at 450°C and 750°C and analyzed using multiple techniques. Results show that co-pyrolysis generally has limited effects on carbon yield and aromaticity but alters mineral speciation and elemental distribution. High rock content also affects hydrogen content, thermal stability, and analytical measurements, offering insights for designing functionalized biochars for enhanced rock weathering.
Fifteen-year stability of soil organic carbon in Pampas agroecosystems: evidence from georeferenced paired-site resampling using equivalent soil mass
Authors: Gonzalo Berhongaray & Roberto Alvarez
Synopsis: Reassessing soil organic carbon (SOC) trends in Argentina’s Pampas Region, this study compares georeferenced soil samples from 40 agricultural sites surveyed in 2007 and resampled in 2023. Using consistent sampling and analytical methods, the researchers find no significant change in SOC stocks over the approximately 15-year period. The results suggest that historical SOC depletion has slowed or stabilized, potentially reflecting the adoption of no-till farming, higher productivity, and diversified crop–pasture rotations. Continued monitoring is needed to determine whether this stabilization will lead to sustained carbon gains.
Bioleaching of olivine and enstatite with formation of Mg-oxalate mediated by engineered Gluconobacter oxydans
Authors: Jacob D. Klug, Luke Plante, James L. Adair, Alia Almansoori, Joseph J. Lee, Stephanie Murillo Maikut, Buz Barstow & Esteban Gazel
Synopsis: Investigating bioleaching as a pathway for carbon mineralization, this study tests a genetically engineered Gluconobacter oxydans strain for simultaneously removing CO₂ and recovering critical elements from ultramafic rocks. The bacterium enhances mineral dissolution and promotes magnesium oxalate formation, which has greater carbon storage capacity than magnesite. Experiments show that up to 75% of magnesium can be leached, although only 11% contributes to carbon sequestration after 15 days. The findings highlight the potential of combining carbon storage with critical-element recovery to improve economic viability.
Moving fast without breaking things: The benefits of preprinting for CDR research - Preprint
Authors: Tyler Kukla , Chris Allen
Synopsis: Rather than focusing primarily on individual benefits such as increased feedback, citations, and visibility, this perspective highlights preprinting as a tool for strengthening scientific coordination. It argues that improved coordination is particularly valuable for the carbon dioxide removal field, which must advance rapidly while maintaining scientific rigor.
Beyond biomass: rethinking forest carbon credits for credible climate finance in India
Authors: Rajendra Kumar Joshi, Satish Chandra Garkoti
Synopsis: Assessing forest carbon accounting and crediting practices in India, this study highlights the underrepresentation of soil organic carbon and microbial processes, which account for an estimated 30–50% of total forest carbon. Their exclusion can undervalue more durable carbon stocks and contribute to over-crediting transient biomass. Spatial analysis shows that tropical wet evergreen, montane temperate, and alpine forests have particularly high carbon finance potential. The study proposes integrating belowground carbon, permanence-weighted valuation, and ecosystem-based approaches to improve the integrity of forest carbon markets.
Cadmium enhances biochar-based carbon sequestration in soils via cation bridging and microbial toxicity
Authors: Huayue Nie, Chang Shen, Xuliang Han, Zikai Lai, Mingwei Chen, Chenxiao Hu, Lanfang Han
Synopsis: Using a 60-day incubation experiment with δ¹³C isotopic tracing, this study investigates how cadmium (Cd) contamination influences carbon sequestration in biochar-amended soils. Cd was found to enhance carbon retention by suppressing the mineralization of both biochar and native soil organic carbon. The mechanisms involved increased macroaggregate formation, stronger adsorption of dissolved organic carbon through cation bridging, and reduced microbial biomass due to Cd toxicity. These interacting effects suggest that Cd contamination can unexpectedly increase biochar-based carbon sequestration in polluted soils.

Postdoctoral Fellowship: Particle Dynamics in the Ocean with Applications to Marine Carbon Dioxide Removal at Hourglass Climate, in partnership with Dalhousie University and Carbon to Sea Initiative
“Mineral-based marine carbon dioxide removal approaches involve releasing reactive olivine mineral particles or particle slurries into the ocean. The effectiveness of these approaches depends strongly on what happens immediately after release. The research will focus primarily on understanding the initial dynamics of particle slurry releases, particularly how release conditions such as slurry concentration, discharge rate, particle properties, and release configuration affect particle transport through the water column. A central goal is to quantify how rapidly released particles travel from the ocean surface toward deeper water or the seafloor, how turbulent mixing influences their trajectories and residence time, and how much dissolution occurs during this transport.”

Biological Carbon Pump Storage in Oceans: Huge Importance of Marine Snow Rates and Water Pressure | Paul Beckwith
“Biological Carbon Pump Storage in Oceans: Huge Importance of Marine Snow Rates and Water Pressure
The oceans of the world sequester around 25 to 26% of yearly anthropogenic emissions of CO2 into the atmosphere.
The primary mechanism for absorption of carbon is the so called Biological Carbon Pump, whereby phytoplankton and small plant life like diatoms capture the carbon in the water for their growth.
Much of this carbon then falls as so-called “marine snow” from the near surface regions into the deep ocean. If it makes it to the deep ocean floor, the carbon can be stored for thousands to hundreds of thousand years.
However, the two new studies I chat about find out that somewhere from 50 to 60% of the carbon in the marine snow is re-released into the water column when the marine snow reaches depths of between 2 and 6 km due to the massive hydrostatic water pressure.”
