Enhanced rock weathering through adding silicate rock powder to soil has been increasingly considered as an effective means of removing CO2 from the atmosphere. However, the potential impact of silicate rock powder addition on the stability of soil organic carbon remains largely unknown, which adds an uncertainty to its effectiveness in mitigating atmospheric CO2. In this study, the response of soil CO2 efflux to wollastonite addition was evaluated for 12 land-use types in a subtropical region of China through an incubation experiment.


Meeressauger fürs Klima

Wolfgang Kempkens, Frankfurter Allgemeine, 28.02.23, Paywall

“Die Ozeane binden enorme Mengen Kohlendioxid. Forscher des MIT (Massachusetts Institute of Technology) wollen sich das mit einem neuen technischen Verfahren zunutze machen und das Klimagas abscheiden, wo es hoch konzentriert und gebunden ist: im Meerwasser.”


HSWT eröffnet Zentrum für Moorforschung

Petra Schnirch, Sü, 27.2.2023, 21:51 Uhr

“Am Freitag, 17. März, eröffnet das Peatland Science Centre (PSC) , in Freising ein Wissenszentrum für Moorforschung. Das neue Zentrum soll die wissenschaftliche Basis für die Moorentwicklung nicht nur in Süddeutschland verbessern und regionale Lösungen anbieten, mit Blick auch auf Biodiversität, Wasserhaushalt und Produktivität. Die Leitung übernimmt Matthias Drösler, Professor für Vegetationsökologie an der HSWT, der seit vielen Jahren zum Thema Klimawandel und Moore forscht.”


Governance of Ocean-Based Carbon Dioxide Removal Research under the United Nations Convention on the Law of the Sea

Wil Burns IN: University of Maine Law Review 75(1)  (2023), 38-70

This article seeks to establish the contours for regulation of ocean-based CDR under the United Nations Convention on the Law of the Sea (UNCLOS). It discusses the potential risks and benefits of the most prominently discussed ocean CDR options and suggests how UNCLOS’s provisions on marine scientific research might be applied to ensure effective global governance of such research.


Call: Recent advances and outlook in carbon capture, utilisation, storage, and atmospheric removal

Abstract submission Deadline: March 1st at 23:59 CET

for Goldschmidt Conference; Lyon, 9.-14. July

This session will focus on a wide range of geochemical, biogeochemical, and mineralogical aspects of carbon dioxide removal and storage in a range of reservoirs and environments. The coveners invite contributions from all aspects of carbon dioxide removal research, including lessons from natural systems, assessment of storage potential, reservoir permeabilities and possible migration pathways, geochemical and numerical modelling, fluid-rock interaction studies, using CO2 for enhanced oil recovery, fundamental mineralogy, laboratory experiments, biogeochemical approaches, carbonation of diverse wastes, and utilisation of carbonated products.


Report: Development of Novel Materials for Direct Air Capture of CO2: MIL-101 (Cr)-Amine Sorbents Evaluation Under Realistic Direct Air Capture Conditions 

Christopher W Jones, Ryan P Lively, Matthew J Realff; Final Report, United States, 2023; doi:10.2172/1907464

The overarching goal of this project is to evaluate the CO2 adsorption properties of a small family of metal-organic framework (MOFs) materials functionalized with amines at sub-ambient conditions. The authors use the sub-ambient lab instrumentation designed or adapted to study the behavior of the pristine metal organic framework (MOF) MIL-101(Cr) and the MOF in the presence of amines ranging from small molecules (e.g. TREN, tris(2-aminoethylamine)) to oligomers (e.g. PEI, poly(ethyleneimine)).


Silveira et al. (2023): Bioenergy with Carbon Capture and Storage (BECCS) in Brazil: A Review

Brenda H. M. Silveira, Hirdan K. M. Costa, Edmilson M. Santos IN: Energies 16(4);

This research aims to provide a systematic literature review of the effective potential of and barriers to implementing bioenergy with carbon capture and storage in Brazil. The platforms chosen for this study are Science Direct and Integrated Search Portal, which is a search portal administered by the University of São Paulo. The search initially identified 667 articles, of which 24 were analyzed after selection and screening.


Nature – Gvein et al. (2023): Potential of land-based climate change mitigation strategies on abandoned cropland

Maren H. Gvein, Xiangping Hu, Jan S. Næss, Marcos D. B. Watanabe, Otávio Cavalett, Maxime Malbranque, Georg Kindermann, Francesco Cherubini IN: Commun Earth Environ 4, 39 (2023).

The authors compare alternative land-based mitigation options by integrating historical and future (up to 2050) abandoned cropland with site-specific biomass yields and life-cycle emissions. Considering natural revegetation in biodiversity priority areas and different measures in the remaining land can achieve a mitigation potential of 0.8–4.0 GtCO2-equivalents yr−1 (2–11% of 2021 global CO2 emissions).


Canatoy et al. (2023): Importance of biochar as a key amendment to convert rice paddy into carbon negative

Ronley C. Canatoy, Seung Tak Jeong, Song Rae Cho, Snowie Jane C. Galgo, Pil Joo Kim IN: Science of The Total Environment 873,

To evaluate the net impact of biochar application on the net global warming potential (GWP) in rice paddy, no organic amendment (control), fresh manure, compost, and biochar treatments were selected during the whole investigation period. Compared to compost, biochar application decreased annual CH4 and N2O emissions by 55 and 31 %, respectively. Biochar application converted rice paddy into a C sink having a net GWP of −0.104 to −0.191 Mg CO2-eq ha−1.


Climate Negotiations in Times of Multiple Crises – Credibility and trust in international climate politics after COP 27

Marian Feist & Oliver Geden IN: SWP Comment 2023/C 10, 17.02.2023, 6 Pages; doi:10.18449/2023C10

With regard to emission reductions, there is a credibility crisis that threatens to worsen, not only because political priorities have shifted following Russia’s attack on Ukraine. In order to strengthen international climate cooperation in the coming years, it will be crucial to honour existing commitments, adhere to agreed processes, and show diplomatic tact in dealing with partner countries.
