THIS WEEK’S TOP CDR HIGHLIGHTS

FIRST CDR DEAL UNDER PARIS AGREEMENT: Norway and Switzerland signed the first bilateral CDR deal under Article 6.2 of the Paris Agreement, enabling cross-border CO₂ transfers through CDR pilots. By 2028–29, they plan to trade 1K-10 Kt of BECCS CO₂ from Norway and 100-1 Kt of mineralized CO₂ from Switzerland.

JOB OPPORTUNITY: Apple is hiring a Carbon Program Manager to lead carbon removal efforts, manage vendor partnerships, and support its 2030 climate goals. Role based in Cupertino with annual pay ranging from $139K–$259K.

CALL FOR INPUT: CDRJobs has launched the 2025 CDR Salary Survey to track how the industry has evolved over the past year. Results will be published in a forthcoming report.

RESEARCH PAPER: A new study finds that the world’s trees, even working collectively, can’t absorb enough carbon to offset emissions from the fossil fuel reserves of the 200 largest oil, gas, and coal companies. Offsetting the 182 Gt CO₂ would require reforesting all of North and Central America, costing a whopping $10.8 trillion.

FIRST VERIFIED OAE CREDITS: Planetary issued the first-ever verified Ocean Alkalinity Enhancement carbon credits, certified by Isometric, removing 625.6 tCO₂ for Stripe, Shopify, and British Airways.

RESEARCH PAPERS

Potential of CO2 sequestration through accelerated weathering of limestone on ships

Authors: Sijia Dong, William M. Berelson, Pierre Forin, Melissa Gutierrez, Dustin Carroll, Dimitris Menemenlis, Albert Y. Kyi, and Jess F. Adkins

Synopsis: This study evaluated Accelerated Weathering of Limestone (AWL) on ships as a carbon removal method. Using updated calcite dissolution kinetics, simulations showed AWL could cut maritime CO₂ emissions by 50%, with <1.4% rise in surface alkalinity and DIC over 10 years, and minimal ocean pH impact.

Reviews and syntheses: Carbon vs. cation based MRV of Enhanced Rock Weathering and the issue of soil organic carbon

Authors: Jelle Bijma, Mathilde Hagens, Jens Hammes, Noah Planavsky, Philip A. E. Pogge von Strandmann, et al.

Synopsis: This paper critiques carbon-based MRV strategies for Enhanced Weathering (EW) in open systems like farmland, arguing they can't fully capture carbon fluxes. Instead, it proposes using total alkalinity (TA) as a core metric, with a systems-level focus on charge balance over time. Standard titration methods, suited for oceans, are shown to be inaccurate for soil porewaters. A cation-based MRV approach is introduced, translating carbon flux into "cation currency," and key research gaps are outlined.

Carbon offsetting of fossil fuel emissions through afforestation is limited by financial viability and spatial requirements

Authors: Alain Naef, Nina L. Friggens & Patrick Njeukam

Synopsis: This study analyzes the limits of offsetting emissions from the 200 largest fossil fuel companies, whose reserves could emit 673 GtCO₂—well above the 1.5 °C carbon budget. Using reserve and carbon capture data, the study shows that offsetting at >$150/tCO₂ could render these firms financially unviable. The external climate costs of these reserves surpass their market value. Afforestation, while cheaper, would require vast land—displacing ecosystems, communities, and farmland—raising major feasibility concerns.

Sea ice controls net ocean uptake of carbon dioxide by regulating wintertime stratification

Authors: Elise S. Droste, Dorothee C. E. Bakker, Hugh J. Venables, Elizabeth M. Jones, Michael P. Meredith, et al.

Synopsis: A decade of year-round data from the Rothera Time Series shows that winter sea ice duration and ocean stratification drive interannual CO₂ uptake variability in the Southern Ocean. Years with longer sea ice cover absorb ~20% more CO₂. Winter processes are key to accurately tracking CO₂ fluxes in ice-covered regions.

Carbon Removal, Climate Impacts, and Equity: Insights From Expert Elicitation

Authors: Derek Sylvan, Peter H. Howard

Synopsis: Expert surveys reveal key equity concerns around CDR. Climate economists expect climate damages to worsen inequality, while CDR experts flag moral hazard, use of CO₂ for oil recovery, and social/environmental risks. Targeted policies and stakeholder engagement are vital for making CDR more just and effective.

Slow but Sure: Expert Perspectives on Carbon Dioxide Removal Policy in the United Kingdom—Preprint

Authors: Harry Smith, Naomi Vaughan, Johanna Forster

Synopsis: This study explores expert perspectives on the UK’s emerging carbon dioxide removal policies through interviews with 25 stakeholders. Key findings include skepticism of the voluntary carbon market, a call for government-driven CDR demand, and the need for robust MRV standards. Experts also highlight the importance of building state capacity via a dedicated CDR body and recommend ‘net-negative ready’ policies to ensure lasting demand through the UK Emissions Trading Scheme in a likely overshoot scenario.

Updated framework and signal-to-noise analysis of soil mass balance approaches for quantifying enhanced weathering on managed lands-Preprint

Authors: Tim Jesper Suhrhoff, Tom Reershemius, Jacob S. Jordan, Shihan Li, Shuang Zhang, Ella Milliken, Boriana Kalderon-Asael, et al.

Synopsis: This study presents an improved soil-based mass balance framework for quantifying rock powder dissolution in Enhanced Weathering (EW) field deployments—crucial for verifying CO₂ removal for carbon markets. It corrects overestimates by accounting for immobile element enrichment in topsoil and recommends using population means over individual samples. A signal-to-noise analysis shows detection is feasible if application rates, dissolution, and sampling meet key thresholds, guiding more accurate and scalable EW monitoring.

Regulation of Nitrogen Site Distribution and Amine Content in IL@ZIF-8 for Direct Air Capture of CO2

Authors: Xin Yan, Pengtao Guo, Youbin Zhou, Ting Wang, Xianren Zhang, Yunpan Ying, Qingyuan Yang, Dahuan Liu

Synopsis: A dual-functionalized IL@ZIF-8 composite using [TEPA][Py] was developed in this study for efficient low-concentration CO₂ capture. By tuning nitrogen site distribution and amine content, the material shows strong, reversible CO₂ adsorption due to low viscosity and high electron density. This approach offers a promising route for direct air capture technologies.

Psychological and socio-economic drivers of public acceptance for direct air capture and utilization technology

Authors: Alexander R. Keeley, Kyomyoung Koo, Andrew Chapman, Shunsuke Managi

Synopsis: A nationwide survey in Japan (n=3,139) reveals that public support for Direct Air Capture and Utilization (DAC-U) is driven by both technology acceptance and environmental awareness. Older adults show higher tech acceptance but lower environmental concern. Demographics like age, education, and energy costs also shape preferences. The study urges tailored policies—subsidies, demos, and age-specific outreach—to boost DAC-U adoption and support Japan’s 2050 carbon neutrality goal.

Harnessing nature for next-generation CO2 removal

Authors: Hegang Zhi, Songtao Yang, Jiushi Ma, Julian Ignacio Lopez & Jing Tang

Synopsis: This review highlights the need for sustainable CO₂ capture by shifting from costly synthetic materials to nature-inspired and bio-derived alternatives. It explores the structures, mechanisms, and performance of these materials, comparing them to conventional options like MOFs and amines. The goal is to develop next-gen CO₂ sorbents—solid, liquid, or hybrid—with fast kinetics, high efficiency, and long-term stability, advancing carbon neutrality through more accessible, eco-friendly technologies.

The State of the Science for Marine Carbon Dioxide Removal (mCDR) – A Scientific Summary for Policy-Makers

Authors: Vivian, Chris, Boettcher, Miranda, Elliot, Mike, Mengis, Nadine , Merk, Christine, Oschlies, Andreas , Boyd, Phillip, et al.

Synopsis: This document summarizes the current state of marine carbon dioxide removal (mCDR) science, focusing on leading research areas. It covers biologically driven methods like ocean fertilization, biomass sinking, and artificial upwelling, as well as chemically driven approaches such as ocean alkalinity enhancement and direct ocean removal (also called direct ocean capture). These mCDR techniques are seen as essential complements to emissions cuts for achieving net-zero climate goals.

Performance prediction for Stommel’s perpetual salt fountain in the context of artificial ocean upwelling

Authors: Jost Kemper, Jan Mense, Jörn Kröger, Thomas Slawig, Kai Graf, Ulf Riebesell

Synopsis:This study introduces two new methods—RANS-based and 1D pipe flow models—for predicting the performance of Stommel Upwelling Pipe (SUP) systems, which are being explored for artificial ocean upwelling in marine CDR. These models address past limitations, are validated through verification and comparison, and offer a reliable basis for assessing SUP potential in bringing nutrient-rich deep water to the surface to support carbon dioxide removal.

Potential impacts of marine carbon dioxide removal on ocean oxygen

Authors: Andreas Oschlies, Caroline P Slomp, Andrew H Altieri, Natalya D Gallo, Marilaure Gregoire, Kirsten Isensee, et al.

Synopsis: This review assesses how marine carbon dioxide removal (mCDR) methods impact ocean oxygen levels. Model results show that biotic approaches—like ocean fertilization and biomass sinking—can cause oxygen loss 4–40 times greater than the gains from reduced warming. These methods may also intensify daily oxygen fluctuations, affecting marine life. In contrast, geochemical mCDR methods or biotic approaches that avoid in-ocean remineralization have minimal oxygen impacts. Oxygen monitoring is essential for all mCDR assessments.

Mechanistic Insights into CO2 Adsorption on Cementitious Surfaces: Coverage and Pre-Hydration Effects from First-Principles Calculations

Authors: Zirou Liu, Xinhang Xu, Danial Jahed Armaghani, Dino Spagnoli, Chongchong Qi

Synopsis: This study used first-principles calculations to explore CO₂ adsorption on β-C₂S(100) and M3-C₃S(001) cement surfaces. Adsorption strength rose with CO₂ coverage, though trends varied by surface. M3-C₃S(001) showed stronger, more stable binding due to surface oxygen ions. Site saturation and electrostatic effects influenced behavior at high coverage. Pre-hydration reduced CO₂ uptake. Findings offer atomic-level insights to improve CO₂ capture in the cement industry.

THESIS

Evaluating the techno-economic potential of combined geothermal, bioenergy and CO₂ removal cycles for power production and net-negative emissions for Aotearoa and beyond

Authors: Titus, K. A.

Synopsis: This study proposes geothermal-BECCS as a novel, co-located solution for renewable energy and CDR, overcoming key limitations of conventional BECCS. By combining geothermal power with bioenergy and CO₂ injection via aqueous dissolution, the system enhances electricity output (62–589 kWe per kg/s flow) and achieves strong negative emissions (-131 to -922 gCO₂/kWh). Techno-economic analysis shows geothermal-BECCS can be cost-competitive, especially in New Zealand, with potential for up to 4 MtCO₂/year removal—exceeding the country’s current carbon budget overshoot. Results support pilot deployment in mature geothermal economies.
