RESEARCH PAPERS
Global Carbon Budget 2025
Authors: Pierre Friedlingstein, Michael O’Sullivan, Matthew W. Jones, Robbie M. Andrew, et al.
Synopsis: This paper synthesizes methods and datasets used to quantify the global carbon budget, including fossil emissions, land-use change emissions, atmospheric CO₂ growth, and ocean and land carbon sinks. It shows that in 2024, total anthropogenic CO₂ emissions rose to about 11.6 ± 0.9 GtC yr⁻¹, with atmospheric CO₂ reaching 422.8 ppm, while land and ocean sinks absorbed a large fraction of emissions but left a remaining budget imbalance. The study highlights persistent uncertainties—especially in land-use change emissions, northern land fluxes, and ocean uptake—while confirming a near-consistent long-term carbon budget with remaining discrepancies at annual to decadal scales.
Decarbonizing desert greenhouse crop production with direct air capture–based CO2 enrichment
Authors: Zulma Lopez-Reyes, Wesley Hopwood, Jonathan Jones, Rod Wing, Raffaella Sordella, Carlos Grande & Rebekah Waller
Synopsis: High-tech greenhouses in hot-desert regions rely on carbon dioxide enrichment to boost crop yields, but current liquid CO₂ supply chains are costly and emissions-intensive. This study evaluates adsorption-based DAC systems—temperature-vacuum-swing (TVSA) and moisture-swing (MSA)—as on-site alternatives for CO₂ supply. Integrated techno-economic and life-cycle analysis shows that DAC-based enrichment can match conventional costs while reducing lifecycle emissions by eliminating transport-related CO₂. Performance is most sensitive to electricity price, carbon intensity, and sorbent efficiency. When powered by low-carbon solar electricity, DAC-enabled greenhouses offer a lower-emission and potentially cost-competitive pathway for sustainable high-yield agriculture in arid environments.
Impact on oysters in first-of-its-kind field trial of marine Enhanced Rock Weathering (mERW) with olivine as Carbon Dioxide Removal (CDR) strategy
Authors: Emilia Jankowska, Matthew Sclafani, Bonnie X. Chang et al.
Synopsis: Marine enhanced rock weathering (mERW) using minerals like olivine is being explored as a carbon dioxide removal strategy that could also reduce ocean acidification, benefiting calcifying organisms such as oysters. This study presents results from the first field trial of mERW, examining oyster growth and trace metal accumulation over short and long timeframes. Oysters exposed to olivine showed no significant differences in biomass compared to controls, and metal concentrations remained low and within safe natural ranges. Overall, the findings suggest that olivine-based mERW has limited biological impacts on oysters while posing no detectable human health risks under the conditions tested.
Biogenic carbon dioxide storage and mineral carbonation uptake in EU buildings
Authors: Dominik Steinberger-Maierhofer, Nicolas Alaux, Delphine Ramon, Semjon Popek et al.
Synopsis: This study quantifies CO₂ storage and uptake in EU buildings across material, building, and building-stock scales, comparing bio-based materials and mineral carbonation against sector emissions. Results show that bio-based materials provide the largest net carbon storage at the building level, while mineral carbonation effects are partly offset by production-stage emissions, leading to net-positive emissions overall. At the EU-27 stock level, biogenic materials contribute only modest net storage (about 1.27% of embodied emissions), while mineral processes increase emissions by around 10.16%, indicating limited net removal potential in current construction systems.
Short-term action is key for gigaton-scale Direct Air Capture by 2050
Authors: Tatjana Zurbriggen, Nicoletta Brazzola, Adrian Odenweller, Falko Ueckerdt & Joeri Rogelj
Synopsis: DAC is increasingly viewed as essential for net-zero pathways, but its ability to scale to climate-relevant levels depends strongly on early deployment dynamics rather than long-term demand alone. This study uses probabilistic diffusion modelling based on historical analogs such as ammonia synthesis and LNG to project DAC growth to 2050. Results show that without rapid early expansion, DAC is likely to remain at megaton scale, while gigaton-scale removal is only achievable under strong policy support and accelerated growth. The findings emphasize that near-term capacity building is the key determinant of long-term DAC impact.
Removing carbon, governing deployment: public perceptions of industry and community roles in U.S. carbon dioxide removal policy
Authors: Celina Scott-Buechler
Synopsis: Public attitudes toward CDR governance in the United States strongly favor democratic oversight, community involvement, and public accountability. A nationally representative survey shows that most respondents support mandatory local consultation, with many also favoring community ownership or voting stakes in CDR projects, and public ownership being preferred over private control by a 2:1 margin. Support for CDR is influenced by who endorses it, increasing with environmental NGO backing and decreasing with fossil fuel company involvement. While concerns include cost, effectiveness, and industry motives, many respondents also associate CDR with job creation and improved air quality, highlighting the importance of governance design in shaping public acceptance.
Direct evidence for enhanced mineral weathering in cropland verified by quantitative X-ray powder diffraction
Authors: Kohei Kurokawa, Atsushi Nakao, Kazuki Azuma, Hodaka Tomita, Katashi Kubo, Kazuki Nomura, Junta Yanai
Synopsis: ERW removes atmospheric CO₂ by applying crushed silicate rocks to soils, but direct evidence of in-soil mineral dissolution has been limited. This study uses quantitative X-ray powder diffraction to track basalt mineral changes in cropland over a 2.5-month buckwheat cultivation period with basalt application. Results show significant depletion of key minerals—especially pyroxene and bytownite—in plant root zones, confirming active weathering. Estimated CO₂ removal reached up to 7.2 tCO₂ per hectare over the study period. The findings provide direct mineral-level evidence of ERW and demonstrate a method for improved monitoring, reporting, and verification of soil-based carbon removal.
Not one shoe fits all: Applicability of hydrodynamic models for the simulation of ocean alkalinity enhancement in the Baltic Sea
Authors: Anna-Adriana Anschütz, Thomas Neumann, Peter Holtermann, Hagen Radtke
Synopsis: This study tests hydrodynamic model reliability using passive tracer simulations in the Baltic Sea Gotland Deep across different model configurations and resolutions. Results show large variability in predicted vertical transport, which significantly affects estimates of how quickly alkalinity reaches the surface and enables CO₂ uptake. The findings highlight that even well-calibrated ocean models can produce divergent outcomes, underscoring the need for dedicated validation of transport processes when modelling OAE and similar marine applications.
Strategic research priorities for marine climate interventions in Australia
Authors: Kerryn Brent, Lennart Bach, Andrew Lenton, et al.
Synopsis: Marine climate interventions (mCIs) include ocean-based carbon dioxide removal strategies and solar radiation management approaches aimed at supporting climate mitigation and protecting marine ecosystems. This paper assesses how research into these technologies should advance over the coming decade in Australia, emphasizing the technical, social, and governance barriers that must be addressed. It identifies three key priorities: expanding mCI research, strengthening monitoring, reporting and verification systems, and developing inclusive governance frameworks that engage affected communities and First Nations groups. These steps are framed as essential for informing future decisions on whether and how mCIs could be deployed in national climate policy.
Climate and ecological constraints of cultivating bioenergy crops for climate mitigation in tropical regions
Authors: Robert Fofrich Navarro, Alcen Chiu, Elsa M Ordway
Synopsis: This study shows that large shares of major bioenergy crops such as oil palm, sugarcane, and soybean will be exposed to climate conditions beyond their historical safe climate space by 2060, particularly in tropical regions. Such exposure could significantly reduce bioenergy yield and carbon sequestration potential, with possible declines of up to 67% for oil palm under limited adaptation. The results also highlight a trade-off: expanding cultivation to offset losses could lead to major carbon and biodiversity losses from land-use change, potentially undermining overall climate benefits.
Abrupt alkalinization alters microbial diversity and promotes the proliferation of marine parasites in coastal microcosm experiments
Authors: James A Gately, Sylvia M Kim, Zoe S Welch, et al.
Synopsis: OAE is a carbon dioxide removal approach that increases seawater alkalinity to enhance natural carbon uptake, but its ecological effects remain uncertain. This study tests large, abrupt alkalinity additions in outdoor microcosms using limestone-inspired and NaOH inputs. Results show shifts in microbial communities, reduced diversity, and increased parasitic organisms under low nutrients. Findings suggest potential ecosystem disruption near deployment sites and highlight the need for careful risk assessment before scaling OAE.
Integration of Direct Air Capture with the Chlor–Alkali Process for CO2 Mineralization: Techno-Economic and Life Cycle Assessment
Authors: Minseok Im, Konan Alain Cedric Nzisso, Inhye Kim, Cheol Hun Park, Sunghyun Cho
Synopsis: This paper proposes a novel DAC system integrated with a chlor–alkali (CA) process, called CADAC, which supplies Ca(OH)₂ directly to the DAC unit and removes the need for an energy-intensive calciner–slaker loop. Technoeconomic and life cycle analysis show improved profitability, with net gains of 18.0–35.1 million USD per year and a substantially lower levelized cost of carbon capture, even becoming revenue-generating in many scenarios. Environmental results indicate up to 72.7% reduction in global warming potential compared to standalone CA operations, with potential carbon-negative performance when renewable electricity exceeds 44.3%.
Vegetation-Mediated Soil Organic Carbon Differentiation and Carbon Sequestration Strategies in a Typical Wetland of the North China Plain
Authors: Zonglin Shi, Yan Wang, Xiaoshuang Li, Na Zhang, Sisi Li, Yue Wang, et al.
Synopsis: Wetland vegetation type strongly controls how soil organic carbon (SOC) is stored, transformed, and stabilized in surface soils. This study across Hengshui Lake wetland shows that reed marshes store the most carbon due to anaerobic conditions and strong aggregate protection, while woodlands enhance dissolved and microbial carbon through active microbial processing. In contrast, farmland and wasteland accelerate carbon breakdown and loss due to rapid labile carbon turnover. Differences in bacterial and fungal communities are primarily driven by soil moisture and bulk density, highlighting how vegetation shifts shape distinct carbon sequestration pathways and wetland carbon sink potential.
Larger forest patches have greater per-area productivity
Authors: Yibiao Zou, Gabriel Reuben Smith, Thomas Lauber, Joe Wan, Haozhi Ma, Noel Gorelick, Constantin M. Zohner & Thomas W. Crowther
Synopsis: An analysis of 17 million forest patches in the conterminous USA shows that larger, contiguous forests are substantially more productive per unit area, with a hectare in very large forests being about 38% more productive than in isolated patches. This fragmentation effect has already reduced national forest carbon uptake by an estimated 0.16 GtC per year (14%). Patch size emerges as a stronger predictor of productivity than soil or topography, and global data show similar trends, emphasizing fragmentation as a critical but often overlooked factor in climate mitigation planning.
Committed and irreversible humid heat stress risk in China despite carbon dioxide removal
Authors: Qianrong Ma, Jiayi Mu, Yingxiao Sun, Zhiwei Zhu, Siyan Dong, Leibin Wang, et al.
Synopsis: CDR may not fully reverse humid heat stress, even under net-negative emissions scenarios. This study of China finds that humid heat responds asymmetrically during warming and cooling, with only partial recovery as temperatures decline. The persistence of heat stress is driven by uneven changes in temperature and humidity, along with atmospheric circulation patterns that continue to transport moisture and sustain high heat conditions. As a result, more than 0.2 billion people could remain exposed to severe humid heat, with most of the impact arising from hysteresis effects, highlighting limits to reversibility and the need for adaptation alongside mitigation.
Quantifying capital-energy trade-offs in bipolar membrane electrodialysis for atmospheric and oceanic carbon removal
Authors: Hussain M. Almajed, Bri-Mathias Hodge, Wilson A. Smith
Synopsis: Bipolar membrane electrodialysis (BPMED) combined with DAC and direct ocean capture (DOC) is evaluated as a carbon removal pathway under variable power conditions. The study finds a key trade-off between system size and energy intensity: DAC-BPMED requires smaller membrane area but operates at much higher current densities than DOC-BPMED. As a result, DAC systems are more sensitive to operating costs, while DOC systems are more capital-intensive. Estimated costs range from US$304–1,281/tCO₂ for DAC-BPMED and US$535–2,220/tCO₂ for DOC-BPMED, with potential cost reductions from by-product sales and feedstock concentration.
Fixing carbon credits requires a new financing model
Authors: Benedict S Probst , Florian Egli
Synopsis: Carbon-crediting systems are increasingly central to net-zero strategies, but concerns over low environmental integrity and weak market signals are limiting the scale-up of durable CDR. This paper argues that improving standards and monitoring alone is insufficient, and that a new financing architecture is needed to unlock investment in permanent CDR. It proposes a tiered auction framework that sets explicit removal targets, enforces minimum quality criteria, and uses reverse auctions alongside first-of-a-kind funding to stabilize prices and reduce investment risk. The approach is designed to accelerate deployment of high-integrity carbon removal technologies by improving market certainty and financial viability.
Are mangrove carbon stocks climate-secure? Linking climate risk to blue carbon permanence
Authors: Pradeep Marula Siddappanavara and Jayashree P
Synopsis: Mangrove ecosystems are increasingly used as Blue Carbon assets in climate mitigation strategies, but current carbon accounting frameworks often assume long-term carbon permanence without adequately accounting for climate-driven risks. This review highlights how acute disturbances, chronic sea-level rise, and combined coastal stressors can destabilize stored carbon in mangroves. It identifies a gap between scientific understanding of ecosystem vulnerability and market-based crediting standards, which often overlook future climate hazards. To address this, the paper proposes shifting from static carbon stock accounting to a climate-secure framework that incorporates site-specific risk assessments and stability scoring to improve the integrity of Blue Carbon credits.
Sustained Neutralization of the Warming Response to Emissions through a Portfolio of GHG Mitigation Strategies - Preprint
Authors: Ella Hughes, Zeke Hausfather, Randall Spock, Christopher Van Arsdale
Synopsis: This paper argues that achieving net-zero requires combining emissions abatement with carbon dioxide removal strategies that operate over different time horizons. Because mitigation options affect climate warming on distinct timescales, the authors propose an accounting framework called “sustained warming neutralization,” which converts emissions and mitigation impacts into a unified metric based on continuous global mean surface temperature change. This approach aims to ensure that emissions are fully compensated in both the near and long term, supporting more robust and time-consistent net-zero claims and guiding the design of mitigation portfolios aligned with global temperature stabilization goals.
Distinct Impacts of Carbon Dioxide Removal and Radiation Management on Regional Monsoons
Authors: Qi Zuo, Jian Cao, Mengying Zhao
Synopsis: Climate mitigation strategies such as CDR and radiation management (RM) can reduce global temperatures, but they produce uneven regional impacts on monsoon rainfall. Using a climate model, this study compares how different approaches affect monsoon systems across Asia, North America, and North Africa. Results show that global cooling generally weakens monsoon rainfall in Asia and the Southern Hemisphere, while increasing rainfall in the North American monsoon region. In North Africa, outcomes depend strongly on the specific mitigation method, with CDR reducing rainfall and RM approaches increasing it. These contrasting responses are driven by changes in atmospheric circulation and temperature gradients, highlighting that temperature mitigation may redistribute rather than uniformly improve water availability.

PODCASTS
Viridas Pressurised DAC, El-Sayed | Reviewer 2 does geoengineering
“In this episode, @geoengineering1 speaks with Ahmed El-Sayed of Viridas Technologies, a company aiming to revolutionize Direct Air Capture (DAC) by redesigning the process from the ground up, including the fan system itself.
The conversation explores why DAC remains expensive, largely due to the extremely low concentration of CO2 in ambient air. While most research focuses on developing new solvents and materials to reduce energy use, Ahmed argues that the thermodynamic limits of capture efficiency may already have been reached. Instead, Viridas is pursuing a different strategy i.e. increasing the volume of air processed.
Their proposed high-pressure system reduces contactor size by 70x while delivering more than 3100x better performance through major gains in absorption capacity and absorption rate. Ahmed also discusses the use of scalable, oxygen-resistant solvents derived from widely produced industrial chemicals, and why the future of DAC may depend on breakthroughs in turbomachinery and membrane technologies to drive costs down to ultra-low levels and enable gigaton-scale deployment.
Paper Discussed: Elsayed, A., & Alawadh, T. (2026). Scaling Carbon Removal to Gigaton Capacity using Pressurized Direct Air Capture. https://doi.org/10.26434/chemrxiv.15002130/v1
“Carbon Removal Is a Boots-on-the-Ground Business,” Diego Justiniano, Exomad Green CEO | Carbonsations
“Joining us in today’s episode is Diego Justiniano, CEO and founder of carbon removal company and the world’s largest biochar supplier Exomad Green. Diego shared the company’s journey to its latest milestone of 2.3 million tonnes of CDR credits sold and over 300,000 tonnes delivered, and stressed the importance of understanding that carbon removal requires a hands-on approach to achieve industrial scale.”
How to Pitch Terraset (and other carbon removal buyers)—w/ Taylor Insley, Terraset | Reversing Climate Change
“What do you think of a developer who pitches a carbon dioxide removal buyer as they are coming out of the restroom? Or can’t even enjoy some friendly scones while we all get caffeinated? Or interrupt conversations with business cards?! Forgetting that buyers are people with names and feelings and limited social energy is a tough look to beat.
At a recent Carbon Unbound in Vancouver, today’s guest—Taylor Insley, the Director of Strategic Planning for Terraset—was on a panel that made a splash: she was telling developers, basically, that the way many of them approach buyers is counterproductive.
I wanted to talk to Taylor because she sits in an unusual position. She spent most of her career as a fundraiser, soliciting donors for causes she cares about. Now at Terraset, the turntables have turned. She’s the recipient of pitches for tax-deductible and highly catalytic CDR and other climate interventions. And that perspective shift has taught her something about what works and what doesn’t that I think is genuinely useful for anyone trying to raise money in this space.
But this episode also goes somewhere uncomfortable. We talk about fairness. About whether it should matter that you’re charming and diplomatic, or whether the science and economics should be all that counts. About status and in-groups and the fundamental hypocrisy of caring about relationships when you’re on one side of the table and resenting them when you’re on the other. I brought in the Chinese Imperial Exam, The Godfather, Love on the Spectrum, whether dogs are communists or private property lovers depending upon who has food... It was a lot, but I think we successfully got to the core of this topic.”
The World’s First International CDR Transfers: Lessons from the Inside - with Veronika Elgart and Ane Gjengedal | The CDR Policy Scoop
“Recorded on May 6th at Zurich’s first-ever Climate Week, this is a different kind of episode. Sebastian Manhart and Eve Tamme spent the day inside a series of Swiss government-hosted events on international CDR pilot transfers and brought the microphones with them.
The Switzerland-Norway and Switzerland-Sweden pilots are quietly doing something that almost no one else is: actually testing the full Article 6 machinery for durable CDR transfers, end to end, with real private sector partners at the table. The question is what that process is revealing: about what works, what doesn’t, and how far the rest of the world is from being able to follow.
Eve and Sebastian got to sit down with two people instrumental in making these pilots happen: Veronika Elgart, Deputy Head of International Climate Policy at Switzerland’s Federal Office for the Environment, and Ane Gjengedal, Senior Adviser at the Norwegian Ministry of Climate and Environment. The surprises are real and so are the unresolved tensions around: use cases, corresponding adjustments, and the gap between having regulation on paper and having markets that function.
The honest answer from everyone in the room: this is harder than it looks, it’s taking longer than expected, and starting sooner is the only advice that holds across every jurisdiction.”
CBAM and International Credits: What’s Just Changed? - with Dan Maleski | The CDR Policy Scoop
“The European Commission just published a draft implementing act on CBAM and it quietly opens the door to international carbon credits counting toward carbon border liabilities. The rules are still being written, but the direction of travel is clear.
Co-hosts Sebastian Manhart and Eve Tamme pulled our favourite CBAM expert, Dan Maleski back in for a rapid-fire debrief the day after publication. They wanted to get the Scoop on what’s actually in the act, what’s still missing, and what does it mean in practice for companies, governments, and CDR?
The conversation unpacks the 10% cap on Article 6 credits, why domestic credits face no equivalent limit, and why that asymmetry should raise eyebrows. Dan also flags a real risk: with prices in voluntary carbon markets anything but standardised, the room for manipulation is not hypothetical. And with “independent persons” as the main safeguard, the jury is still out on how watertight this will be.
One thread runs through it all: CBAM is pushing trading partners toward compliance regimes that look more like the EU ETS and for CDR project developers who can align with that compliance demand, the long-term signal is significant.
The consultation closes in early June. While still unresolved, this one is worth watching closely.”
Dr. Christian Komor on Carbon Removal as Infrastructure: Dr. Christian Komor on Climate Urgency, Policy, and the Limits of Incremental Action | Net Zero Compare Podcast
“In this episode: Dr. Christian Komor, climate author and Earth systems strategist, joins Net Zero Compare to discuss why carbon removal should be treated as climate infrastructure rather than a peripheral technology.
The conversation explores one of the central debates in long-term net-zero strategy: whether emissions reduction alone is enough to manage climate risk. Dr. Komor argues that accumulated atmospheric carbon, climate feedback loops, and slow policy response make large-scale carbon removal increasingly urgent. He explains direct air carbon removal, carbon utilization, and the importance of pairing removal facilities with clean energy. A key focus is his SkyCarbon Blueprint, a proposed state-led model for scaling direct atmospheric carbon removal in Colorado through public-private financing, co-located renewable energy, industrial carbon use, and interstate coordination. The episode also examines cost, policy, resilience, public will, and the role of companies while regulation remains uncertain. Ultimately, the discussion highlights that a credible climate strategy may need to combine emissions reduction, carbon removal, adaptation, better data, and systems-level planning.”

The Role of Indigenous Leadership in Carbon Removal | Carbon Removal Canada
“Indigenous communities aren’t just stakeholders in carbon removal. They’re leaders, knowledge holders, and decision-makers shaping what this sector looks like and who it works for.
In this episode, we sit down with Indigenous leaders working at the intersection of land, climate, and carbon removal to hear directly from them: what’s working, what needs to change, and what responsible carbon removal looks like when Indigenous peoples are in the driver’s seat.”
