THIS WEEK’S TOP CDR HIGHLIGHTS

SWEDEN CUTS BECCS FUNDING: Sweden’s 2026 budget reduced subsidies for bioenergy with carbon capture and storage from 36 billion SEK to 30 billion SEK. With 20 billion SEK already allocated to Stockholm Exergi, only 10 billion SEK remains for other bidders.

MCDONALD’S BACKS REGENERATIVE AGRICULTURE: McDonald’s USA has pledged $200 million over seven years to support regenerative ranching across 38 states, aiming to restore grasslands, boost soil health, conserve water, and improve its beef supply chain sustainability.

CALCULATOR FOR AVIATION AND SHIPPING: Robert Höglund developed 4 interactive calculators that compare fuel costs and volumes and removals for aviation and shipping. Two focus on costs, when is which mitigation alternative cheapest. And two on volumes (how much CO₂ removals are needed for shipping and aviation under different shares of biofuels and electrofuels).

WRI DAC ROADMAP: The World Resources Institute released a roadmap outlining how U.S. states can expand direct air capture by advancing policies, infrastructure, and workforce development to achieve climate goals and drive local economic growth.

GOVERNMENT-LED CONTRACTS: UK government has signed contracts for its first commercial carbon capture & storage projects at Heidelberg Materials’ Padeswood cement plant and Encyclis’s Protos waste-to-energy facility. Together they’ll capture 1.2 million tonnes of CO₂ annually and create ~500 skilled jobs.

REPORT: Carbon credits could save the EU around €37 billion annually by 2040 - nearing the same budget as the Common Agricultural Policy - if the bloc allows a mix of high grade solutions to meet its target rather than just geological removals, such as direct air capture and bioenergy combined with carbon capture and storage, according to a new report by BeZero Carbon.

RESEARCH PAPERS

Biochar and its impact on the carbon cycle

Authors: David Chiaramonti, Franco Berruti, Johannes Lehmann, Ondrej Masek, Henrik Ingermann Petersen, Manuel Garcia Perez, Hamed Sanei, Francesco Primo Vaccari
Synopsis: This work corrects misconceptions about biochar-based CDR, showing it does more than shift carbon within the biosphere. Through pyrolysis, biomass carbon is converted into stable aromatic structures with residence times of centuries–millennia, functionally moving it into the geosphere. Biochar thus provides durable atmospheric CO2 removal while also supporting soil health. Its permanence depends on carbonization temperature, not short-term decay, making it a credible long-term mitigation tool.

Mitigation deterrence and unrealistic expectations: the future costs of forest carbon offsets

Authors: Camilla Moioli, Laurent Drouet, Dominik Roeser, Johannes Emmerling, Hisham Zerriffi
Synopsis: Forest Carbon Offsets (FCO) like afforestation, reforestation, and REDD can aid mitigation but face risks of impermanence, overestimation, and deterrence of other actions. Using the WITCH model, results show reliance on FCO cuts renewables (–8.6%) and CCS (–31%) while raising fossil fuels (+1%). Full forest carbon loss by 2045 raises global GDP loss by 0.5 pts, hitting non-OECD nations hardest (+1.7 pts vs OECD). The study calls for accurate MRV, equity-focused policies, and limits on offset use to avoid moral hazards.

Learning increases both acceptability and scrutiny of carbon dioxide removal methods: quasi-experimental evidence

Authors: Felix Dörpmund, David M Reiner, Julia Pongratz and Sabine Fuss
Synopsis: This quasi-experimental study tested how a six-week online CDR curriculum shaped perceptions among climate-engaged participants (n=366 pre, 83 post, 29 matched). Education significantly boosted self-reported CDR knowledge and improved risk-benefit assessments, especially for biochar and enhanced weathering. Rather than simple endorsement, participants developed more nuanced, critical evaluations and shifted from favoring single methods to supporting portfolio approaches. Findings highlight how structured engagement can foster sophisticated public dialogue on CDR.

Challenges and opportunities in scaling enhanced weathering for carbon dioxide removal

Authors: David J. Beerling, Christopher T. Reinhard, Rachael H. James, Anu Khan, Nick Pidgeon & Noah J. Planavsky
Synopsis: This review evaluates the scalability of terrestrial enhanced weathering as a CDR strategy for agricultural lands. With $250M+ raised by start-ups, EW could deliver 0.5–2 Gt CO₂/yr removal by 2050. Key requirements include robust cradle-to-grave carbon tracking, accounting for lag times, and developing rigorous MRV frameworks. Major challenges are high costs, inconsistent carbon crediting methods, and lifecycle emissions. Policy support, farmer acceptance, and long-term (>10 years) field trials are essential to improve CDR efficiency, quantify co-benefits, and ensure sustainable, responsible EW deployment.

The Sequestration Efficiency of the Deep Ocean

Authors: Benoît Pasquier, Richard J. Matear, Matthew A. Chamberlain, Tilo Ziehn, David K. Hutchinson, François W. Primeau, Yi Liu, Ann Bardin
Synopsis: This study presents a computationally efficient offline framework to estimate transit-time distributions (TTDs) of carbon released at the seafloor, overcoming the prohibitive cost of multi-millennial simulations. Applied to an Earth System Model, results show that abyssal plains, particularly in isolated basins like the North Pacific, offer the highest sequestration efficiency, with <10% of water resurfacing after 1,000 years. Climate warming–driven circulation slowdown in the 2090s further extends return times by ~30%, surpassing internal variability (~20%) and enhancing long-term storage potential for CCS and CDR in the deep ocean.

Regional ocean biogeochemical modeling challenges for predicting the effectiveness of marine carbon dioxide removal

Authors: Nicholas David Ward, Nicholas, Kyle Hinson, Rémi Pagès, Jessica Cross, Marjorie A. M. Friedrichs, et al.
Synopsis: This perspective highlights the need to improve ocean biogeochemical models to support the scaling of mCDR. Since direct observations cannot capture counterfactuals or the vast variability of the ocean carbon pool, models are essential for quantifying sequestration, durability, and uncertainty. Current models, built for general ocean dynamics, lack process representations tailored to mCDR. Refining these models to simulate system perturbations across scales is critical for evaluating deployment impacts, guiding monitoring, and verifying long-term carbon storage.

Earth system responses under a global 2 °C-target scenario aligned with China’s carbon neutrality pledge

Authors: Yixiong Lu, Lei Jin, Junting Zhong, Xiaoye Zhang, Yanwu Zhang, Fanghua Wu, et al.
Synopsis: This study introduces a new SSP2-com scenario integrating China’s 2060 net-zero pledge with global CDR deployment to evaluate a 2 °C-consistent pathway. Using an Earth system model, SSP2-com limits end-of-century warming to 1.87 °C—0.51 °C cooler than SSP2-4.5 and 1.47 °C cooler than SSP3-7.0. Accelerated Chinese decarbonization contributes to 0.08–0.29 °C of avoided warming despite weaker carbon sinks. Results show that ambitious national pledges, combined with large-scale CDR, are essential to stabilize below 2 °C, while highlighting risks from uneven regional cooling and ecosystem feedbacks.

Bridging time lags in durable carbon removal on working lands

Authors: Noah J Planavsky, Beck J Woollen, Ella Milliken, Mojtaba Fakhraee, David J Beerling, Christopher T Reinhard
Synopsis: This study argues that while enhanced weathering and biochar can deliver durable carbon dioxide removal, their climate benefits are delayed due to time lags between deployment and realized removal. The authors propose coupling these methods with point-source methane reductions to create a robust crediting framework. Such integration would enable immediate and continuous offsets of anthropogenic emissions, strengthening the effectiveness and credibility of carbon credit systems.

Novel field trial for ocean alkalinity enhancement using electrochemically derived aqueous alkalinity

Authors: Allison M. Savoie, Mallory Ringham, Carolina Torres Sanchez, Brendan R. Carter, Sean Dougherty, et al.
Synopsis: This study reports the first field trial of electrochemically generated alkalinity-enhanced seawater released via a wastewater treatment plant (WWTP) in Sequim Bay, WA, as part of an Ebb Carbon–PNNL collaboration. Alkalinity dosing raised WWTP mixing tank pH to 9.0 (the regulatory maximum), with elevated pH signals detected only within ~2.5 m of the outfall, peaking at 8.1–8.3 during February 2025 releases. No measurable effects on temperature, salinity, turbidity, or oxygen were observed. Results demonstrate proof-of-concept for safe, small-scale ocean alkalinity enhancement deployment via existing coastal infrastructure.

Enhanced Rock Weathering Promotes Soil Organic Carbon Accumulation: A Global Meta-Analysis Based on Experimental Evidence

Authors: Tongtong Xu et al.
Synopsis: This global meta-analysis of 74 studies evaluates the effect of ERW on soil carbon dynamics. Field data show that crushed rock amendments increase SOC by up to 3.8%, with even larger gains in mineral-associated (6.1%) and particulate organic carbon (7.5%), driven by higher exchangeable Ca, microbial biomass, and improved soil structure. Machine-learning simulations reveal strong site dependency: SOC gains in warm, humid low-latitudes but losses in cold, dry high-latitudes. Optimal application rates (50–500 g m⁻²) maximize SOC sequestration, while higher doses reduce effectiveness. Findings confirm ERW’s potential for durable CDR, but stress the need for site-specific management tailored to climate, soil, and application strategy.

Carbon dioxide supply and scaling constraints on direct air capture using calcium oxide powder

Authors: Lance Dostie, Ian M. Power, Kwon Rausis
Synopsis: Calcium oxide (CaO) looping shows promise for CO₂ removal but is strongly limited by CO₂ supply, even at high flow rates. Tests with CaO and Ca(OH)₂ powders reveal carbonation efficiency rises with CO₂ concentration, with rates halved at 100 ppm vs ambient. Column trials show diffusion limits in CaO layers ≥0.5 cm, achieving 64 wt% CaCO₃ and ~32 kg CO₂/m²/yr removal. Scaling requires matching CO₂ supply with mass and thickness, underscoring supply as the key bottleneck for large-scale deployment.

Quantifying asynchrony between microbial necromass and soil organic carbon for sustainable soil carbon management

Authors: Xuefeng Zhu, Joshua Schimel, Chao Liang
Synopsis: Microbial products and residues, key to soil organic carbon (SOC) storage, are central to the soil Microbial Carbon Pump (MCP). This review outlines MCP’s role in SOC transformation, introduces the △MCP efficacy metric (tracking microbial necromass-to-SOC ratio changes), and provides a framework linking necromass dynamics with SOC storage. It highlights synchronous and asynchronous responses, urging research to assess dynamic shifts in necromass–SOC interactions for sustainable soil carbon management.

Aggregated monitoring of enhanced weathering on agricultural lands - Preprint

Authors: Tim Jesper Suhrhoff, Anu Khan, Shuang Zhang, Beck J Woollen, Tom Reershemius, Mark A. Bradford, Alexander Polussa, Ella Milliken, Peter A. Raymond, Chris Reinhard, Noah Planavsky
Synopsis: Terrestrial enhanced weathering (EW) on farmland offers scalable CDR with agronomic co-benefits but relies on VCM-driven MRV. This study shows aggregated monitoring across fields improves detection and reduces uncertainty: river chemistry at larger catchments reveals clear weathering signals, soil and gas flux errors shrink when pooled, and pre-defined aggregation avoids bias. Aggregated MRV strengthens quantification, lowers costs, and enables policy integration, supporting EW’s path to climate-relevant scale.

Enhancing soil organic carbon sequestration through slope-to-terrace conversion and mixed planting: Insights from carbon pool composition and biomarker dynamics

Authors: Guan Wang, Sheng Zhang, Zihe Zhou, Jinhua Cheng
Synopsis: This study assessed SOC dynamics in hilly farmlands of SW China under slope-to-terrace conversion and mixed planting. Terracing boosted SOC and mineral-associated carbon by 105–204% and 116–338%, enhancing retention. Mixed planting raised labile carbon, microbial biomass, and necromass >10%, with bacterial inputs dominant in maize and fungal in citrus. Yet, microbial residue and lignin contributions to SOC remained constant, indicating no major gains in long-term SOC stability despite larger pools.

Substantial forest soil carbon accrual from absorptive fine roots over decadal timescales

Authors: Ning Ma, Shenggong Li, M. Luke McCormack, Grégoire T. Freschet, Philippe Ciais, Huimin Wang, et al.
Synopsis: This study shows that fine absorptive roots of mycorrhizal trees are major but underrecognized contributors to forest soil carbon. Across Northern Hemisphere forests, root turnover and slow decay add ~2.4 ± 0.1 MgC ha⁻¹ over 20 years—65% more than leaves. Arbuscular mycorrhizal roots contribute 43% more SOC than ectomycorrhizal roots, despite the latter dominating global stocks. Specific root length emerges as a useful proxy for modeling root-driven carbon accrual in Earth system models.

Holocene to anthropocene burial of organic carbon in the Yangtze delta

Authors: Jianfeng Su, Yijing Wu, Daidu Fan
Synopsis: Using borehole and surface sediment data, this study reconstructs Holocene–Anthropocene organic carbon (OC) burial in the Yangtze Delta. From 8–2 ka, weaker monsoons reduced terrestrial OC input, yet stable burial (~0.79 Mt/yr) persisted. After 2 ka, human activities drove a 78% rise in burial (~1.40–1.44 Mt/yr). Post–Three Gorges Dam, erosion cut burial rates by 59%, shifting the delta from a net OC sink to a net source (~0.81 Mt/yr exported). Results highlight how human-driven sediment dynamics can reverse deltaic carbon sequestration, with global relevance for mega-deltas.

Amine free direct air capture integrated with buildings’ cooling systems in humid environments

Authors: Yasser M. Abdellatif, Riham Surkatti, Raeesh Muhammad, Ahmed Sodiq, Nashaat Nassar, Tareq Al-Ansari, Abdulkarem I. Amhamed
Synopsis: This study introduces an integrated DAC system that couples adsorption-based CO₂ removal with air handling units using a silica gel wheel for dehumidification. By reducing water–CO₂ co-adsorption, the system boosts sorbent efficiency (NbOFFIVE, Zeolite-13X, functionalized SBA-15, Lewatit) and cuts regeneration energy demand—by 82% for NbOFFIVE and 39% for amine-functionalized SBA-15. The integrated setup lowers total thermal energy use by 57.8% compared to standalone DAC + HVAC operation, and by 13.8% versus HVAC alone, demonstrating strong potential for efficient DAC deployment in humid environments.

Electrochemical Carbon Removal Mechanisms in Solid Oxide Fuel Cells: An Optical and Electrochemical OperandoStudy

Authors: William Maza, Elias D. Pomeroy, Daniel A. Steinhurst, Cameron M. Priest, Stanislav Tsoi, Jeffrey C. Owrutsky and Robert A. Walker
Synopsis: This study investigates mechanisms of electrochemical carbon removal from Ni-YSZ cermet anodes in solid oxide fuel cells (SOFCs) at 800 °C using complementary optical and electrochemical methods. Near infrared thermal imaging revealed symmetrical thermal patterns during carbon oxidation, while FTIR spectroscopy detected rapid CO and CO₂ evolution. Chronoamperometry confirmed heterogeneous oxidation, with carbon near the current collector removed at high currents and distal carbon oxidized at lower currents. Findings indicate that electrochemical oxidation dominates at higher currents, while catalytic gasification by electrochemical products governs at lower currents.

Incorporating enhanced rock weathering into sustainable forest management

Authors: Minger Guo, Ian M. Power, Shaun A. Watmough, Adam S. Gorgolewski, Larissa M.M. Wallisch, Jonathan Spence, Sasha Wilson
Synopsis: This field trial tested the integration of ERW into forest management by spreading wollastonite-rich rock powder via trail networks in Haliburton Forest, Ontario. At a target rate of 5 t/ha, ERW could offset historical Ca losses and sequester 1120–1270 t CO₂/yr across ~700 ha, with a broader potential of 4.5–5.1 Mt CO₂/yr for US and Canadian selection-harvest forests. The trial confirmed technical feasibility but revealed strong spatial variability in application (0.8–6.7 t/ha) due to trail geometry, tree obstructions, and overlaps, complicating accurate carbon crediting. The study recommends targeted site monitoring and dosage verification to ensure reliable CDR estimates and credit validation in future forest ERW deployment.

Enhanced carbon dioxide mineralization of industrial alkaline wastes through date palm waste-derived activated biochar

Authors: Maisa El Gamal, Ameera F. Mohammad, Basim Abu-Jdayil, Suhaib Hameedi, Imen Ben Salem
Synopsis: This study develops a low-cost carbon capture material by combining activated biochar (BC) from date palm waste with industrial alkaline waste (ladle furnace slag, AW-LF). Pyrolysis (450–750 °C) with K₂CO₃ or H₂O₂ activation enhanced porosity and reactivity, boosting CO₂ uptake. The best-performing blend (10% BC + AW-LF) captured 0.94 mmol/g, while K₂CO₃-activated BC increased cumulative uptake by ~380% over unmodified slag. Characterization (XRD, FTIR, SEM, TGA) confirmed stable CaCO₃ formation and durable binding, with ~8% weight loss attributable to carbonation. The process is scalable, circular-economy aligned, and cost-effective (∼$1.80 per 100 g H₂O₂-BC), offering a promising pathway for sustainable CO₂ removal.

CDR Credits from the Global South: Problem or Solution? - with Fiona Mugambi | The CDR Policy Scoop

CDR Credits from the Global South: Problem or Solution? - with Fiona Mugambi

The CDR Policy Scoop

26:47

“The EU’s 2040 Climate Target debate is heating up. At stake: whether to allow international carbon credits at all - and if so, how many and what kind.
The European Union is split: some push to ban credits outright, while others want to allow plenty and as early as 2031. The current 3% proposal would mean up to 400 Mt of international credits by 2040.
Such a volume could literally ignite whole industries across numerous countries, with all the benefits that can bring to local communities. But the concerns centre around whether it would water down the EU’s own climate action.
Should the EU be allowing international credits, especially from the Global South, to achieve its climate targets? If so, should it focus on durable removals and be limited only for hard to hard-to-abate emissions?
Co-hosts Eve Tamme and Sebastian Manhart are delighted to be joined by Fiona Mugambi, Head of Growth & Partnerships at Octavia Carbon and Policy Lead at The Global South CDR Coalition. Fiona brings first-hand insights from Africa’s leading DAC initiative and a coalition that can shape debates in Brussels.”

Climate Week NYC 2025 at SOM: “Carbon Sink Cities” | Skidmore, Owings & Merrill

“As the climate crisis intensifies, the moment to introduce radical ideas for carbon removal feels more urgent than ever. This Climate Week NYC, we hosted a mobilization event in our New York studio in partnership with City CDR Initiative, XPRIZE, Conservation International, Carbon Neutral Cities Alliance, and Climate High-Level Champions.
The afternoon of panel discussions and more featured SOM Partners Adam Semel, Chris Cooper FAIA, LEED AP, and Carrie Moore, who joined leading voices—city officials, Indigenous leaders, urban designers, planners, and carbon removal experts—to explore “Carbon Sink Cities: How to Catalyze Carbon Removal for Sustainable, Resilient, and Inclusive Cities.”
Inspired by our Urban Sequoia research, the radical concept of a Carbon Sink City introduces the idea of an entire city being designed in a way that it can absorb carbon. It offers a powerful framework for climate action, transforming the urban environment into a more resilient, sustainable, and inclusive form of human settlement.”
