RESEARCH PAPERS

Land–energy nexus to assess the contribution of carbon dioxide removal in net-zero emission pathways
Authors: Sophie Chlela, Nicklas Forsell, Sandrine Selosse
Synopsis: A systems-level modelling approach is used to examine how land and energy systems interact in delivering climate mitigation through carbon dioxide removal, particularly via bioenergy. By coupling the TIAM-FR energy model with the GLOBIOM-G4M land-use model, the study explores how large-scale energy crop deployment could support deep decarbonisation pathways. Results indicate that achieving Paris-aligned targets may require 54–55 EJ/year of bioenergy and up to ~215 million hectares of dedicated land in net-zero scenarios, alongside substantial negative emissions (up to ~−4 GtCO₂/yr in a 1.5°C pathway). The analysis also highlights strong trade-offs between land use, energy demand, and technology costs across DACCS and BECCS routes.
Rock-enhanced biochar exhibits similar priming effect as pure biochar application while improving short-term carbon stabilization in agricultural soils
Authors: Maria Ansari, Annemarie Lübeck, Johannes Meyer zu Drewer, Nikolas Hagemann, Annette Eschenbach & Joscha N. Becker
Synopsis: This incubation study explores how combining biochar with silicate rock powder influences soil carbon dynamics and stabilization processes. Using ¹³C-labeled biochar across three soil types, the results show that pure rock powder has minimal short-term impact, while biochar largely drives observed effects in combined treatments. Soil texture and pH strongly control outcomes, with sandy soils showing positive priming of native SOC. Although priming responses are similar across biochar-based treatments, rock-enhanced biochar produced via co-pyrolysis leads to greater short-term gains in mineral-associated organic carbon, suggesting improved stabilization potential.
Is mCDR pollution? Rethinking pollution for the governance of marine carbon dioxide removal
Authors: Lina Röschel
Synopsis: Governance of mCDR remains fragmented, with the London Convention and Protocol serving as a key regulatory anchor by classifying certain marine interventions as potential pollution. This perspective argues that while this framing enables precautionary oversight, conventional technocratic definitions of pollution are too narrow to fully capture the implications of mCDR. Instead, it proposes a relational understanding of pollution as the reconfiguration of social-ecological systems, offering a broader conceptual lens for interpreting and improving governance without abandoning existing institutional structures.
Hidden carbon storage in the continental lithosphere revealed by Mg-Zn isotopes of adakite-like magmas
Authors: Jian Xu; Xiao-Ping Xia; Omar Bartoli; Qiang Wang
Synopsis: This study investigates the fate of carbon during subduction by analyzing Mg and Zn isotope signatures in Oligocene adakite-like granites derived from partially melted metasediments. The geochemical data indicate a clear contribution from recycled carbonate-bearing sediments, suggesting that subducted carbon can be stored efficiently in the deep continental crust through diapiric relamination. While this process helps explain discrepancies in global subduction carbon budgets, the authors also note that later partial melting of these carbon-rich reservoirs during post-collisional stages may release CO₂ back to the atmosphere, linking deep Earth carbon storage to long-term climate regulation.
How well do global ocean approaches constrain local fCO2?
Authors: Galen A McKinley, Amanda R. Fay, Thea Hatlen Heimdal, Lauren Moseley and Abby Shaum
Synopsis: Ocean carbon uptake is key to global climate regulation, but this study shows current models and observation-based products struggle to resolve local-scale CO₂ variability needed for marine carbon dioxide removal (mCDR) monitoring. Using independent data, it finds that while long-term trends are captured, regional errors in CO₂ fugacity are often 10× larger than expected mCDR signals (~1 µatm). Seasonal variability is a major source of uncertainty, with biases reaching up to 56 µatm in some models. These limitations make it difficult to reliably detect or verify mCDR impacts at local scales, highlighting the need to improve seasonality representation and reduce uncertainty in ocean carbon sink estimates.
Stability assessment of calcium carbonate dissolution as a marine carbon dioxide removal mechanism
Authors: Amanda B. Melendez-Perez, Kimberly Gilbert, Tyler Cyronak
Synopsis: OAE is examined here through its key chemical constraint: avoiding CaCO₃ precipitation that can undermine or reverse carbon removal efficiency. The experiments test seawater with varying alkalinity additions under different temperatures and mixing conditions. Results show clear stability thresholds—low additions (~3,000 µmol kg⁻¹) remain stable for over a month, while high additions (~14,000 µmol kg⁻¹) trigger rapid CaCO₃ precipitation within a day. Intermediate levels show temperature-dependent delays. No runaway alkalinity loss is observed, but stability improves significantly when mixed with natural estuarine waters. Overall, the study defines practical operating limits for CaCO₃-based OAE and highlights the importance of local environmental conditions in deployment design.
Land Models Likely Underestimate the Impact of Future Atmospheric Dryness on European Tree Growth
Authors: Brendan Clark, Daniele Visioni, Shan Kothari, Manuel Lerdau
Synopsis: This study finds that current Earth System Models may overestimate future land carbon uptake because they assume tree growth is primarily limited by photosynthesis. Using dendrometer observations, the authors show that rising vapor pressure deficit (VPD) suppresses tree growth through physiological constraints more strongly than models predict. Incorporating these growth limitations into land models could improve projections of terrestrial carbon storage and future atmospheric CO₂ concentrations.
Amine-loaded sepiolite/carbon aerogels engineered with conductive frameworks for efficient direct air capture and solar/electric-thermal desorption
Authors: Jie Wang, Shuai Wang, Fanshu Ding, Sijin Dong, Changrui Shi et al.
Synopsis: Rather than relying on conventional fossil-fuel-driven regeneration systems, this study presents a low-cost DAC material built from a sepiolite–chitosan–nanocarbon aerogel impregnated with polyethyleneimine. The composite enables efficient CO₂ capture from ambient air (up to 2.86 mmol/g at 400 ppm) and supports dual renewable-energy regeneration via photothermal and electrothermal heating. Rapid desorption is achieved through strong conductive and heat-transfer networks, allowing over 70% CO₂ release in 20 minutes. The design highlights a scalable pathway for energy-flexible, low-cost DAC sorbents.
A Modeling Perspective of Global Carbon Cycle Science: From a Missing Sink to Net Zero
Authors: Pierre Friedlingstein
Synopsis: This overview traces the evolution of global carbon cycle science since continuous atmospheric CO₂ monitoring began in the late 1950s. Early observations confirmed rising anthropogenic CO₂ and revealed the need to understand ocean and land carbon sinks. This drove the development of carbon cycle models, later integrated into Earth System Models (ESMs), which identified a positive climate–carbon feedback in which warming weakens natural sinks and amplifies atmospheric CO₂ accumulation. These insights also established key concepts such as cumulative emissions, the remaining carbon budget, and the near-linear CO₂–warming relationship, forming a scientific foundation for the Paris Agreement and net-zero emissions targets.
Bayesian optimal experiment design for enhanced mineral weathering with gradient boosted decision trees
Authors: Thomas Servotte, Iris Janssens, Jakob Raymaekers, Tim Verdonck
Synopsis: This paper develops new Bayesian Optimization approaches for optimizing complex environmental experiments, particularly in carbon dioxide removal via enhanced mineral weathering. It introduces two Gradient Boosting–based methods: an XGBoost model using Output Configuration scores for uncertainty estimation, and a CatBoost Ensemble that derives uncertainty from prediction variance. Designed for high-dimensional, mixed-variable spaces, these approaches improve scalability over traditional Gaussian Process methods. Benchmark tests across standard optimization functions and a real-world mineral weathering case show the CatBoost Ensemble consistently performs best, outperforming expert-designed experiments and accelerating the identification of optimal carbon sequestration conditions.
Geoengineering: Infrastructures for a Global Climate?
Authors: Simon Dalby
Synopsis: Climate intervention is increasingly shifting from theory toward potential real-world infrastructure as climate risks escalate. This piece examines emerging interest in carbon dioxide removal and solar radiation management as large-scale technical responses to warming. It argues that while these approaches could form the backbone of future climate governance systems, weak institutional frameworks raise uncertainty over whether they will enable global coordination or intensify geopolitical conflict over climate control.
Cation trapping by biochar reduces carbon removal efficiency - Preprint
Authors: Ayesha Ahmed, Tim Jesper Suhrhoff, Chris Reinhard, Noah Planavsky
Synopsis: A closer look at biochar-based carbon removal reveals an often-overlooked source of inefficiency linked to nutrient cycling. This study finds that biochar can immobilize cations and nitrogen that would otherwise cycle through soils and waters, indirectly affecting carbon fluxes and reducing overall carbon dioxide removal effectiveness. Depending on environmental conditions, this mechanism could introduce 0–40% inefficiency in claimed carbon removal. The authors argue that such biogeochemical side effects must be incorporated into monitoring, reporting, and verification (MRV) frameworks to ensure accurate accounting of biochar’s climate mitigation value.
Integrating vision transformers with multi-criteria analysis for direct air capture and CO2 storage (DACCS) siting
Authors: Yifan Xu, Mrityunjay Singh, Cornelia Schmidt-Hattenberger, Marton Pal Farkas, Tomas Fernandez-Steeger
Synopsis: DACCS deployment is framed here as a complex spatial planning problem shaped by energy access, CO₂ transport and storage, regulatory constraints, and social-environmental trade-offs. To address the limitations of region-specific and data-scarce siting studies, the authors propose a hybrid framework combining PESTLE-based GIS multi-criteria decision analysis with a machine-learning surrogate trained on satellite imagery. Applied to the North German Basin and adjacent offshore regions, the system generates high-resolution suitability maps and uses a self-supervised vision transformer (DINOv3) to predict siting potential from Sentinel-2 data, achieving strong agreement with reference outputs (R² ≈ 0.89). The approach enables scalable, transferable early-stage screening of DACCS locations while maintaining interpretability through explicit decision criteria.
Principal Current and Future Methods for Carbon Removal: Applications of Metal Oxides in Environmental Remediation
Authors: Farhad Ali, Asadullah Dawood, Muhammad Ramzan & Zeenat Jabeen
Synopsis: Framed against record-high global CO₂ emissions, this chapter positions metal oxides as a foundational material class across a range of CDR and mitigation technologies. It reviews how different oxide families—alkaline earth, transition metal, and perovskite structures—enable CO₂ capture, mineralization, photocatalysis, and environmental remediation through distinct chemical and electronic properties. While highlighting their versatility, the analysis also underscores key barriers including energy-intensive regeneration, material degradation, toxicity concerns, and supply constraints. The chapter argues that advances in nanostructuring, doping strategies, AI-guided materials discovery, and circular manufacturing could be critical to scaling metal oxide-based solutions toward gigaton-level carbon removal.
Atmospheric methane removal as a third climate intervention: termination risks and air pollutant effects
Authors: Katsumasa Tanaka, Weiwei Xiong, Didier A. Hauglustaine, et al.
Synopsis: AMR is examined as a distinct climate intervention category alongside carbon dioxide removal and solar radiation management. The analysis finds that, because methane has a relatively short atmospheric lifetime, the cooling benefit from AMR is inherently non-durable compared with CO₂ removal. However, its termination effect is less abrupt than that associated with SRM. The study also highlights that AMR influences tropospheric ozone formation, with outcomes strongly dependent on existing background pollution levels, adding complexity to its climate and air-quality impacts.
Comparative environmental assessment of wet and dry carbonation for construction materials using an LCA approach integrating CO2 sequestration kinetics
Authors: Zhenghao Wang, Zoe Li, Pengxiao Zhou
Synopsis: This life cycle assessment evaluates wet and dry carbonation of steel slag as a carbon utilization and storage pathway. The results show that wet carbonation can deliver net-negative emissions (−94.4 kg CO₂-eq per tonne of carbonated slag), while also reducing the carbon footprint of downstream cement applications. However, overall climate benefits vary significantly with regional electricity mixes and end-use pathways, with construction applications like slag-blended bricks offering the largest reductions. The study also links carbonation kinetics to environmental performance, identifying an optimal reaction time (~105 minutes) for minimizing global warming potential and highlighting the importance of process optimization and regional context in scaling slag carbonation.
Direct ocean capture via a pH-swing integrated hollow fiber membrane contactor
Authors: Chihyuk Ahn, Sang Moon Shin, Tae-Hyun Bae
Synopsis: This work presents a DOC system that removes CO₂ from seawater using a pH-swing process coupled with a hollow fiber membrane contactor. By acidifying seawater, dissolved inorganic carbon is converted to CO₂ and extracted across a gas-permeable membrane under ambient conditions, enabling continuous operation without fouling. Transport modeling clarifies mass transfer limitations and supports scale-up design. Techno-economic analysis estimates a baseline cost of $703/tCO₂, largely driven by acid and membrane demands, but suggests potential reductions to ~$127/tCO₂ with improved efficiency and renewable energy integration, and even lower costs in industrial coastal co-location scenarios.
European citizens’ perceptions of responsibility, capacity, and fairness of implementing negative emission technologies and practices
Authors: Chieh-Yu Lee, Goda Perlaviciute & Linda Steg
Synopsis: A large-scale survey of over 5,000 European citizens examines how people judge the fairness of deploying negative emission technologies (NETs) across countries. Using an experimental design, respondents evaluated scenarios based on national emissions (responsibility) and economic capacity. The results show that perceived fairness is strongly driven by a country’s responsibility for emissions, with high-emitting and resource-rich countries seen as more appropriate locations for NET deployment. Respondents also extend these judgments to their own countries based on similar factors. The findings highlight that perceptions of historical responsibility and capacity are central to public acceptance, suggesting fairness considerations should be integrated into NET governance and policy design.

Does Managed MRV imply the existence of Unmanaged MRV?!—w/ Varsha Ramesh Walsh, Offstream | Reversing Climate Change
“What even is MRV, let alone dMRV?! Or Managed MRV?! Doesn’t that imply the existence of Unmanaged MRV? If everything is pretty much digital now, do we still need that pesky ‘d’ letter?! Are there still dudes with clipboards hanging around?
In this episode of Reversing Climate Change, host Ross Kenyon sits down with the cofounder and CEO of Offstream, Varsha Ramesh Walsh, to untangle the complicated web of carbon credit data collection.
Offstream has evolved significantly after realizing that carbon project developers don’t just want another software tool to manage... they want someone to simply get the job done for them. Varsha introduces us to the concept of “Managed MRV,” explaining why handing off the heavy lifting of Monitoring, Reporting, and Verification can sometimes be cheaper and far more effective than trying to handle it all in-house.
But this show also gets big. Varsha argues that practically every piece of modern infrastructure has the potential to become a carbon dioxide removal or environmental asset. For that to be true, we would likely enter a world where we are all much more persistently observed and quantified, and with rewards and punishments to match. Is the future of carbon crediting one of surveillance capitalism with the social contracts of data sharing to match? Would that solve more problems than it creates? How are we even meant to live?!
Varsha also shares her incredibly disciplined approach to information consumption as a founder, offering a highly focused counter-narrative to being “well-informed”.”

Fire-Forged Innovations | Wood Innovation Series | #forestproud
“Our latest film in the Wood Innovation series, Fire-Forged Innovations, takes us to the West Coast to explore how wildfire mitigation and post-fire recovery efforts can create innovative wood products that benefit both forests and communities.
At the center of the story is biochar, a material created from low-value wood and forest byproducts that would otherwise go to waste. In this film, the American Biochar Institute and Executive Director Myles Gray help break down the science of biochar in plain language, showing how it supports forest health, soil productivity, and real-world applications across landscapes.
We then head into the field with Earth Foundries, where founders Roger Smullen and Dede Smullen demonstrate how mobile pyrolysis systems are being used on active wildfire mitigation projects to convert woody debris into biochar. Their work in the Mendocino National Forest highlights how small-scale, on-the-ground efforts can reduce wildfire risk while creating value from materials generated during fuels reduction.
From there, we travel to Burney, California, to see how Pacific Biochar and West BioFuels is scaling this work through large-scale production at the Hat Creek Bioenergy facility, where Josiah Hunt, Matt Summers, and MacKenzie Castruita, share how biochar is produced at scale and applied in real-world settings. The story comes full circle on agricultural land, where biochar is applied to soils - connecting forest management to benefits that extend beyond the woods.
Supported by the U.S. Forest Service Wood Innovations Program, Fire-Forged Innovations shows how partnerships and practical solutions are turning today’s forest management challenges into opportunities for healthier forests and more resilient communities.”

From Farmland to Carbon Markets: Evaluating Enhanced Rock Weathering Across Australia & Southeast Asia | TESS Centre
“Durable carbon dioxide removal (CDR) technologies are increasingly recognized as essential for meeting long-term climate targets, yet their deployment remains limited by economic, technical, and policy uncertainties. Drawing on a detailed case study, we apply Life Cycle Assessment (LCA) and Techno-Economic Analysis (TEA) to evaluate the full Enhanced Rock Weathering (ERW) supply chain, from feedstock processing and transport to field application and post-deployment monitoring. In North Queensland, spatially optimised cradle-to-farm LCA of basalt and mill ash on farmlands shows basalt delivers substantially higher and more robust net CDR, while mill ash becomes viable only under targeted, low-transport deployment. In Southeast Asia, cradle-to-credit modelling of ERW in agricultural supply chains indicates strong carbon-insetting potential, where logistics dominate emissions and MRV dominates costs. Stakeholder perspectives from both regions further highlight governance, market readiness, and supply-chain coordination as deployment priorities.”
How Ocean Alkalinity Enhancement Removes Carbon from our Oceans with Planetary Technologies | Earthlings 2.0 The Podcast
“In this episode of Earthlings 2.0, we speak with Michael Kelland, CEO and Co-Founder of Planetary Technologies, about whether the ocean could play a much larger role in helping remove carbon dioxide from the atmosphere. For decades, the ocean has served as one of Earth’s largest carbon sinks, absorbing roughly a quarter of human-generated CO2 emissions. But that service comes at a cost: ocean acidification, which threatens coral reefs, shellfish, and marine ecosystems worldwide. Michael explains how Planetary Technologies is using a climate solution known as coastal seawater restoration, also called ocean alkalinity enhancement, to restore ocean chemistry, increase the ocean’s natural ability to absorb carbon dioxide, and provide long-term carbon removal. The conversation explores how ocean carbon removal works, the science behind ocean alkalinity enhancement, the challenges of measuring and verifying carbon removal, and what it will take to scale climate technologies that can help the world reach net-zero emissions.”
