Science – Stuart-Smith et al. (2023): Legal limits to the use of CO2 removal

Rupert F. Stuart-Smith , Lavanya Rajamani, Joeri Rogelj, Thom Wetzer IN: Science 382 (6672), pp. 772-774, DOI: 10.1126/science.adi9332

In the lead up to this year’s United Nations (UN) Climate Conference (COP28) in Dubai, the authors present scientific and legal bases for our argument that emission-reduction pathways that depend heavily on CDR may contravene norms and principles of international law.


Nemet et al. (2023): Near-term deployment of novel carbon removal to facilitate longer-term deployment

Gregory F. Nemet, Matthew J. Gidden, Jenna Greene, Cameron Roberts, William F. Lamb, Jan C. Minx, Stephen M. Smith, Oliver Geden, Keywan Riahi IN: Joule 2023,

This commentary shows that the deployment of novel CO2 removal (CDR) over the next decade, its formative phase, is likely to be consequential in determining whether CDR will be available at scale and in time to reach net-zero CO2 emissions consistent with the Paris Agreement’s temperature goal.


Webinar: MRV for Ocean-Based CDR: Spotlight on CDR Suppliers

Thursday, November 30, 7 – 8pm CET

Join Ocean Visions for the second webinar in their series on current innovations in measurement, reporting, and verification (MRV) for ocean-based carbon dioxide removal (CDR). They will spotlight leading startups doing electrochemical CDR to get a deeper understanding of the current state of MRV science, how it’s being applied, and the challenges and solutions advancing this important field. Talks by CDR scientists Erika La Plante, PhD (Equatic) and Sophie Chu, PhD (Captura) will be followed by a moderated audience Q&A.


Nature – Anderson et al. (2023): Controversies of carbon dioxide removal

Kevin Anderson, Holly Jean Buck, Lili Fuhr, Oliver Geden, Glen P. Peters, Eve Tamme IN: Nature Reviews Earth & Environment,

Various methods of carbon dioxide removal (CDR) are being pursued in response to the climate crisis, but they are mostly not proven at scale. Climate experts are divided over whether CDR is a necessary requirement or a dangerous distraction from limiting emissions. In this Viewpoint, six experts offer their views on the CDR debate.


Edenhofer et al. (2023): On the Governance of Carbon Dioxide Removal – A Public Economics Perspective

Ottmar Edenhofer, Max Franks, Matthias Kalkuhl, Artur Runge-Metzger; CESifo Working Paper No. 10370

This working paper highlights the importance of carbon dioxide removal (CDR) technologies for climate policy. The authors first describe their role in iconic transformation pathways and discuss removal costs and storage duration of different technologies. Based on economic principles, the authors characterize optimal removal flows and reservoirs for non-permanent removals. Furthermore, they discuss different pricing regimes that achieve an optimal allocation under different information and liability conditions.


White Paper: Digital Infrastructure for Carbon Removal, Nov 8

The Carbon Business Council and Climate Collective published a white paper about Digital Infrastructure for Carbon Removal. Developed by a working group of Carbon Business Council members and affiliates and published with generous support from the Climate Collective, the white paper outlines key challenges the carbon removal sector faces; identifies opportunities where digital infrastructure can offer solutions to help address these challenges; and puts forth a set of focused recommendations for the carbon removal sector on the adoption of digital technologies.


How Carbon Trading Can Unlock Carbon Dioxide Removals

by Malek Al-Chalabi & Hasan Muslemani; The Oxford Institute for Energy Studies (

In this Energy Comment, the importance of carbon trading and the challenges it faces are presented including how carbon trading can help countries achieve net zero. In particular, based on a combined academic and industry review, this article focuses on the importance of carbon dioxide removal (CDR) activities and examines the role that carbon trading can play in unlocking their potential and highlighting, as a top priority, the need for carbon removal projects to be internationally recognized and supported particularly within Article 6 of the Paris Agreement.


This Is CDR Ep.86: Communicating Carbon Removal with Dr. Rob Bellamy

on youtube, 1h

In this episode of „This Is CDR“, OpenAir welcomed Dr. Rob Bellamy to discuss his recent paper „Communicating Carbon Removal.“ Dr. Rob Bellamy is Lecturer in Climate and Society in the Department of Geography at the University of Manchester. His research focuses on the social science of climate, nature, and technology, exploring how climate change and responses to it are perceived, evaluated, and governed. He is currently Co-Investigator and Lead on Responsible Innovation for the UK’s national carbon dioxide removal directorate hub, CO2RE.


Nature – Nemet et al. (2023): Dataset on the adoption of historical technologies informs the scale-up of emerging carbon dioxide removal measures

Gregory Nemet, Jenna Greene, Finn Müller-Hansen, Jan C. Minx IN: Communications Earth & Environment 4,

Here the authors present the Historical Adoption of Technology dataset—a set of harmonized global annual time series from the early 20th century to present. They use three growth metrics to compare historical growth to that of carbon removal in emissions scenarios and future targets. The authors find heterogeneity in growth rates in the diffusion of historical technologies, ranging from 1.1 to 14.3% (median 6.2%) for their preferred growth metric based on a logistic function.


Equinor and Captura To Scale Innovative Ocean CO2 Removal

by Sasha Ranevska,, November 1

„The multinational energy company Equinor and the direct ocean capture (DOC) company Captura have announced a partnership to develop industrial-scale solutions to remove carbon dioxide from the ocean. The two companies hope that this collaboration could potentially be a starting point for building large-scale commercial plants in key regions globally.“
