The analysis highlights ERW’s ability to sequester CO₂ while improving soil fertility and structure, but also identifies key barriers to scaling, including operational challenges, limited long-term field data, the need for standardized verification, and stronger economic assessments.
Authors: Johannes Meyer zu Drewer, Maria-Elena Vorrath, Thorben Amann, Jens Hartmann, Maria Ansari, Marcela Cárcamo Pérez, Nikolas HagemannSynopsis: Investigating the combination of ERW and pyrogenic carbon capture and storage (PyCCS), this study evaluates whether biochar and basalt-based amendments can enhance carbon dioxide removal. Controlled experiments show that co-deployment, particularly rock-enhanced biochar, produces more carbonate alkalinity than pure rock powder or separate applications. The findings suggest ERW–biochar combinations could improve carbon storage durability and provide additional soil benefits, although further field validation is needed.
Authors: Jeffrey Dankwa Ampah, Chao Jin, Haifeng Liu, Mingfa Yao, et al.Synopsis: Introducing a “Co-Scale” pathway, this study explores a climate strategy where CDR and rapid decarbonization advance in parallel rather than competing with each other. Model results suggest that this approach could achieve net zero earlier, increase cumulative carbon removal, reduce the duration of 1.5°C overshoot, and limit long-term warming more effectively than CDR-led or decarbonization-led pathways. The authors highlight geological storage capacity as a key constraint for scaling.
Authors: Uzoma E. K & Adeniyi M. OSynopsis: This study examines how CDR could affect the water balance across West Africa using climate model simulations. The results project slightly wetter conditions in parts of the Sahel by 2100 but reduced precipitation and surface runoff in several countries, including Burkina Faso, Ghana, Togo, Benin, and Nigeria. While spring and summer remain predominantly moist, the study also identifies an increased risk of flooding in forested regions during summer.
Authors: Viola Heinrich, Amelia Holcomb, Simon Besnard, Daniela Requena Suarez, et al.Synopsis: Synthesizing evidence from 146 studies, this analysis examines how partial disturbances affect aboveground carbon (AGC) stocks in tropical moist forests. The findings show that fires, selective logging, and edge effects cause major immediate carbon losses, with more frequent and intense disturbances amplifying declines. However, degraded forests that retain some structure demonstrate stronger recovery potential than forests regrowing after complete deforestation, providing valuable insights for carbon accounting and climate mitigation strategies.
Authors: Bonnie G. Waring, Colin Averill, Martin Bidartondo, et al.Synopsis: Reporting results from an 11.5-hectare field trial, this research explores combining ERW with soil microbiome modification to boost forest carbon capture. Monitoring 6,400 trees over four years showed that crushed silicate rock increased aboveground carbon stocks in broadleaf forests, while forest-soil inoculation produced variable growth benefits. The findings suggest integrated approaches could enhance reforestation carbon sequestration, though further research is needed on long-term ecological mechanisms.
Authors: Corey R Lawrence, Harun Niron, Tania Timmermann, Philip D Weyman, Yun-Ya Yang, Daniel Dores, Gonzalo A Fuenzalida-MerizSynopsis: Exploring microbially accelerated weathering (MAW) as a CDR approach, this study investigates whether soil microbes can enhance natural silicate weathering without adding externally sourced minerals. A 63-day soybean mesocosm experiment found that microbial treatment increased available base cations and promoted carbonate formation, achieving measurable CO₂ removal. The results support MAW as a potentially lower-footprint alternative to conventional enhanced weathering, though further validation is needed.
Authors: Candelaria Bergero, Jing Cheng, Qiang Zhang, Yang Ou, Haewon McJeon, Morgan R. Edwards, Destenie Nock, Inês Azevedo & Steven J. DavisSynopsis: Examining the air quality consequences of different net-zero pathways, this study evaluates how reliance on CDR influences community-level health outcomes across the United States. The modelling shows that all pathways reduce PM2.5-related deaths compared with continued emissions, but scenarios with lower residual emissions and less CDR dependence deliver greater health benefits, particularly for non-white and low-income communities. The findings highlight the importance of equitable climate transition planning.
Authors: Nimarta Kaur, Ahmad Al-Bodour, Santiago Aparicio, Mert AtilhanSynopsis: Reviewing the current landscape of DAC, this paper examines the key scientific and engineering challenges involved in removing CO₂ from the atmosphere. It explores advances in sorbent materials, contactor designs, and regeneration methods while highlighting the energy challenges of capturing carbon at very low atmospheric concentrations. The review outlines pathways for improving DAC efficiency and scaling the technology toward large-scale climate mitigation.
Authors: Karthik Ramanna, Simon Roston, Lauren Holloway, Robert S. KaplanSynopsis: Introducing the E-ledgers method, this document proposes a framework for accounting and auditing carbon removals through verifiable, near real-time tracking of greenhouse gas emissions and removals embedded in products and services. The proto-standard aims to improve transparency and interoperability in carbon accounting systems, supporting emerging regulatory efforts and enabling consistent approaches for assessing carbon removal assets across jurisdictions and industries.
Authors: Seungyeol LeeSynopsis: Reviewing advances in calcium-based mineral carbonation, this paper explores how engineered limestone formation could provide a pathway for permanent CO₂ storage. It examines the distinction between true carbon dioxide removal using atmospheric or biogenic CO₂ and conventional carbon capture applications involving fossil emissions. The review covers feedstocks, carbonation processes, energy requirements, environmental impacts, and challenges for scaling mineralization technologies toward gigatonne-level deployment.
Authors: Boseong Kim, Hyung Woo Lee, Yeo Jin Yoon, Eun Ju Kang, Changsin Kim, Jin Woo Kang et al.Synopsis: Quantifying the carbon uptake potential of cultivated kelp, this study estimates the net primary production of seaweed aquaculture using field measurements and modelling of photosynthesis, light availability, and biomass changes. Results show strong seasonal variation, with intensive kelp cultivation achieving higher productivity than natural populations. The findings provide a foundation for evaluating seaweed-based marine carbon dioxide removal (mCDR), while highlighting the need to assess the long-term fate and durability of stored carbon.
Authors: L.A. Bullock, A. Cunningham, J. Matter, D. Hasson, E. Smith, M.T. Duret, E.M. Mervine, R.H. James, D.A.H. TeagleSynopsis: Assessing mining by-products as potential feedstocks for enhanced rock weathering, this study investigates whether platinum group metal (PGM) residues could support CDR. Laboratory experiments show that mine tailings and slags dissolve faster than several conventional silicate materials, suggesting significant theoretical potential. However, the authors caution that real-world deployment faces limitations from CO₂ availability, water flow, and field conditions, requiring process intensification or additional methods to achieve large-scale removal.
Authors: Wei Hou, Yingfeng Ran, Ziliang Liang, Zihao Peng, Xiangguo Lin, Junzhi LiuSynopsis: Developing a high-resolution approach for forest carbon monitoring, this study combines drone LiDAR, airborne LiDAR, satellite imagery, and ground data to improve carbon storage estimates. By separating forests according to structural complexity, the modelling framework achieves greater accuracy than conventional approaches. Applied in China’s Tongshan District, the method reveals significant carbon storage potential from restored mining areas and supports improved monitoring of nature-based climate solutions.
Authors: Jinge Zhou, Hua He, Han Chen, Jingfan Zhang, Zhe Lu et al.Synopsis: Investigating carbon sources within coastal blue carbon ecosystems, this study analyses organic carbon storage in two Chinese saltmarshes using molecular biomarkers and isotope techniques. The results show that plant-derived carbon dominates sediment carbon pools, contributing more than 75%, while microbial and external marine or terrestrial inputs play smaller roles. The findings improve understanding of carbon accounting methods needed to accurately quantify and manage blue carbon credits.
Authors: Zhenghao Yang, Yulong Chang, Hongguang Zhang, Dianhang Wei et al.Synopsis: Introducing a pilot-scale pyrolysis-separation dual fluidized bed system, this study explores improvements to biomass pyrolysis efficiency and carbon outcomes. The technology enables in-situ biochar recovery while using pyrolysis gas for energy regeneration, producing higher-quality bio-oil and reducing emissions from biochar combustion. Results indicate improved energy efficiency, lower production costs, and potential for achieving negative carbon emissions through optimized biochar utilization.
Authors: Cristian Mihai Enescu, Mircea Mihalache, Leonard Ilie, Lucian Dinca, Irina Sfeclă, Adrian Ioan Timofte and Gabriel MurariuSynopsis: Assessing the role of oak forests in climate mitigation, this review combines bibliometric analysis and literature synthesis to evaluate their carbon sequestration potential. Drawing on 656 publications, the study finds that oak ecosystems act as significant long-term carbon sinks through biomass, deadwood, litter, and soil carbon storage. The authors highlight oak forests as resilient nature-based climate solutions, while emphasizing the importance of species composition, site conditions, stand age, and management practices.
Authors: Tian Gao, Jiaojun Zhu, Xiao Zheng, Lining Song, Yirong Sun, Dexiong Teng, and Xinhua ZhouSynopsis: Challenging claims that afforestation could transform the hyperarid Taklamakan Desert into a major carbon sink, this commentary highlights key ecohydrological limitations. The authors argue that extremely low rainfall, high evaporation, groundwater depletion, and climate risks make large-scale vegetation expansion difficult to sustain. While afforestation can contribute to carbon removal, they caution that projected carbon gains in desert environments require careful assessment of water availability, costs, and long-term ecosystem stability.
Authors: Halime Joloro, Ghasem Ali Dianati Tilaki, Hadi Memarian & Yahya KoochSynopsis: Evaluating the economic value of ecosystem carbon sequestration, this study examines how land-use transitions affect long-term carbon benefits in Iran’s Kojur watershed. Using InVEST modelling and carbon price forecasting, the analysis finds that converting agricultural and rangeland areas to forests provides the greatest economic gains, while expansion of rainfed croplands causes significant losses. The results emphasize the importance of forest conservation and land-use planning for climate mitigation.
Authors: Ji-Hyun Park, Mu Yeol Lee, So-Jeong Kim, Chan-Mi Choi & Young-Soo HanSynopsis: Investigating basalt application in agricultural soils, this study examines how enhanced rock weathering influences microbial activity and greenhouse gas emissions from paddy fields. Laboratory experiments show that increasing basalt concentrations reduced CO₂ and methane emissions, partly through mineral-driven carbon trapping and changes in microbial communities. The findings suggest basalt amendments could provide a dual benefit by supporting carbon removal while reducing agricultural greenhouse gas emissions.
Authors: Youzhi An, Mengyi He, Huili Bao, Peng Zhao, Jin Sun, and Fengtai ZhangSynopsis: Using the Chengdu–Chongqing urban agglomeration as a case study, this research models how future land-use changes could influence carbon storage under different climate scenarios. The analysis shows that urban expansion into cropland has contributed to carbon losses, while forest restoration increases carbon storage. Future SSP126 projections achieve the highest carbon storage through greater forest expansion, highlighting ecological restoration as an important nature-based climate solution.

There are 592 jobs available *right now*: check them all out at: CDRjobs Board PODCASTS“Most net zero policies and major scientific models rely on carbon dioxide removal (CDR) to limit global heating to 2℃. The most commonly known methods include afforestation, bioenergy with carbon capture, and direct air capture - but various proposals are emerging for ocean-based CDR technologies.Could marine CDR offset emissions from sectors that cannot easily decarbonise, or are the costs and risks too great? Bertie sat down with oceanographer David Ho to discuss these questions, shortly after he returned from the 4th International Conference on Carbon Dioxide Removal in Milan.David Ho is a professor at University of Hawaiʻi at Mānoa, and a lead author on the upcoming IPCC methodology report on carbon dioxide removal and carbon capture, utilisation and storage. His 2023 article for Nature criticising overreliance on CDR has been downloaded more than 100,000 times.”

“Tune in to the latest episode of our EUnpacked podcast series, where we unpack the forthcoming revision of the EU Emissions Trading System (EU ETS) – the EU’s flagship climate policy and one of its most consequential regulatory frameworks for business. With the European Commission’s legislative proposal which has just been postponed for publication on 17 July. The debate is intensifying around key issues including the future pace of emissions reductions, reforms to free allocation, the role of carbon removals and international credits, and the possible extension of the system to new sectors. In this episode, Freshfields’ EU Regulatory & Public Affairs Senior Consultant Karl Thies is joined by James Chapman, Partner in the firm’s Energy and Infrastructure practice, and Stefan Schröder, Partner in the firm’s Energy Regulatory practice, to discuss what the revision could mean for companies’ investment decisions, competitiveness, and decarbonisation strategies in the years ahead.”
“What happens when you care about climate and also want to explore space? What if you love technology but worry we’ve deeply misunderstood how to relate to it appropriately? What happens when we take the religious claims of others seriously, even when they aren’t seen as legitimate as the major faiths? How can philosophy, literary criticism, film, and media studies help solve some of the biggest questions in climate, and maybe even give us all a little bit of extra solace in a time when we sure could use it?Today’s a biggie. We talk about some huge concepts, but don’t be scared. They’re simple enough. You’ll get the hang of it while walking your dog and listening to this and soon you’ll be able to wow your friends and family with some fancy new $5 words.In all seriousness though, I think these concepts are genuinely useful, and have helped me make sense of my own feelings, how my brain works, and how to understand what it means as a little person to relate to ideality, materiality, and the Antropocene.”
“In this episode of The CDR Policy Scoop, Sebastian Manhart and Eve Tamme are joined by Kaya Axelsson, Research and Policy Fellow at Oxford Net Zero, just days after what she describes as the most anticipated Monday of her year: June 22, when both the ISO Net Zero Standard and the SBTi Corporate Net Zero Standard launched at London Climate Action Week. Kaya spent three years inside both standard-setting processes, and the conversation captures what this convergence moment actually means for companies, for carbon markets, and for carbon removal.The episode opens on what Kaya calls the single global playbook. Her case: the two standards don’t fundamentally contradict each other. ISO is wider in scope, internationally governed via WTO-compatible processes, and a natural tool for trade policy, green public procurement, and claims legislation, particularly in markets across Africa and Asia that SBTi has yet to reach. SBTi brings detailed near-term implementation guidance and the momentum of eleven thousand companies already signed up. Kaya explains how she sees companies using them together and what each does better than the other.But she is not without concerns. The episode surfaces a significant one: a potential communication error in the SBTi standard that risks allowing companies to claim net zero alignment without ever setting a long-term net zero target. For CDR, the implications are direct. SBTi’s decision not to require removals purchases before 2035 is, in Kaya’s view, a cost-based rather than science-based call, and a missed opportunity to start scaling the supply of what companies will eventually need. ISO, by contrast, requires five-year removal milestones from the outset.The conversation closes on what comes next: the governance of commodity certificates such as green steel, SAF, cement, which both standards now actively encourage companies to purchase. Kaya predicts this will be the defining debate at the next London Climate Action Week, and explains why getting the governance architecture right matters as much as the demand signal itself.”
“In this episode of The CDR Policy Scoop, Sebastian Manhart and Eve Tamme sit down for their second quarterly, unscripted catch-up of the year, working through what is actually moving in CDR policy right now with no guest in the mix, just two co-hosts comparing notes.The conversation opens on the member state CDR targets expected by the end of the year and why a patchwork of twenty seven national targets could be a net positive for the sector, forcing a wider range of technologies and approaches into play rather than funneling everyone toward the EU ETS. From there they turn to the ETS integration itself, unpacking a Potsdam Institute modeling exercise on how CDR volumes between forty and eighty megatons a year by twenty forty could stabilize carbon prices, and Sebastian previews a new peer reviewed paper on using ETS revenue to front load investment into removals through European Investment Bank bonds.They then dig into aviation, a sector Sebastian and Eve agree the CDR community has been too quiet on. The ReFuelEU Aviation review looks unlikely to open the door to removals, and the two make the case for a coordinated push before the window closes. That leads into CORSIA, where enforcement turns out to be far weaker and far more geographically uneven than either expected, and where Sebastian argues the real opportunity may lie with nature based removals rather than durable ones.The episode closes on Article 6.4 as the presumed foundation for future international credit quality criteria despite still-undefined removal methodologies, and on Norway’s new NOACCS auction scheme, a sizable but narrowly targeted funding mechanism that raises questions about how well governments are learning from each other’s programs.”

Can Rocks Remove CO₂? UNDO CTO Explains Enhanced Rock Weathering | RAW GREEN “Can crushed rock really remove CO₂ from the atmosphere?In this episode of RAW GREEN, Francesco De Lieto and Emma Mee speak with Mat Meredith, Chief Technology Officer at UNDO (https://un-do.com/), about enhanced rock weathering (or ERW) one of the most promising carbon dioxide removal technologies with potential to scale to gigatonnes.The idea sounds simple: take silicate rocks such as basalt or wollastonite, crush them finely, spread them on agricultural land, and let rain, soil chemistry and natural weathering remove CO₂ from the atmosphere.But the real challenge is not only spreading the rock. It is proving the carbon removal actually happened.Mat explains enhanced rock weathering in plain English, how different rocks behave, what happens to the captured carbon, and why measurement, reporting and verification (or MRV) is the biggest challenge for ERW.We also discuss UNDO’s work with farmers and landowners, the soil-health benefits of rock spreading, the carbon footprint of quarrying and processing, the role of carbon credits, the instability of voluntary carbon markets, and what needs to happen for enhanced rock weathering to become bankable and scalable.This is a conversation about rocks, rain, soil, carbon removal, climate finance, MRV, farmers, carbon credits and whether ERW can become one of the major tools in the fight against climate change.”
