Prairie et al. (2023): Restoring particulate and mineral-associated organic carbon through regenerative agriculture

Aaron M. Prairie, Alison E. King, M. Francesca Cotrufo IN: PNAS, https://doi.org/10.1073/pnas.2217481120

To better understand soil organic carbon (SOC ) formation and persistence, the authors separate it into two distinct forms, particulate organic carbon (POC) and mineral associated (MAOC). This study presents results from a global meta-analysis on the response of SOC, POC, and MAOC, to regenerative agricultural practices including no-till, cropping system intensification, and integrated crop–livestock (ICL). The authors found that regenerative practices increased both POC and MAOC, thus improving soil health and promoting long-term carbon storage.

Carbon Capture Summit 2023

26 – 27 June, 2023, Holiday Inn Arena Towers, Amsterdam, Netherlands

Industry leaders will meet to explore next-generation technologies for carbon capture, utilisation, storage, and transportation. The key focus for this year’s Carbon Capture Summit 2023 will be “Working in collaboration with the industry” by sharing expertise, building capacity, and providing advice and support so CCUS can play an integral role in reducing carbon emissions. Government agencies, global corporations, research bodies, and non-government organisations committed to learning and adopting CCUS technologies will participate in this event.

Rickels et al. (2023): Potential efficiency gains from the introduction of an emissions trading system for the buildings and road transport sectors in the European union

Wilfried Rickels, Christian Rischer, Felix Schenuit, Sonja Peterson IN: Kiel Working Paper, No. 2249, Kiel Institute for the World Economy
ISSN 1862–1155

In the European Union (EU), a second emissions trading system (EU ETS2) covering buildings, road transport and small energy and industrial installations is expected to be introduced from 2027. The authors study the EU ETS2 for the year 2030 using the general equilibrium model DART. In the analysis, the introduction of an EU ETS2 generates about a quarter of the efficiency gains of a comprehensive emissions trading system, assuming that nation states use the flexibility mechanisms of the ESR and compensate for regional abatement leakage through interstate emissions trading.

Can ‘enhanced rock weathering’ help combat climate change?

by Jonah Fisher, BBCNews, 21.05.2023

„In a quarry surrounded by the din of heavy machinery Jim Mann crouches down and picks up a handful of tiny black rocks. „This is my magic dust,“[…] UNDO has plans to rapidly scale up over the next few years and has attracted some serious supporters. Microsoft has agreed to pay for 25,000 tonnes of basalt to be scattered on UK fields. As part of the deal Microsoft will also help audit the project and verify that it is working as intended.[…]This year UNDO is planning to spread 185,000 tonnes of basalt and hopes by 2025 to have removed a million tonnes of CO2.“

Ein Endlager für Treibhausgas

Verena Tang, Spektrum der Wissenschaft, detektor.fm, podcast: 16 min

„CO₂ unter der Erde speichern: Das ist technisch möglich und nach Ansicht vieler Fachleute notwendig, um die Klimaziele zu erreichen. In Deutschland ist das Verfahren aber bislang verboten. Nun wagt die Bundesregierung einen neuen Anlauf. Ein Überblick über die Technologie, ihre Chancen, Grenzen und Risiken.“

Denny et al. (2023): Carbon Farming: Nature-Based Solutions in Brazil

Danielle Mendes Thame Denny, Carlos Eduardo Pellegrino Cerri, Maurício Roberto Cherubin, Heloisa Lee Burnquist IN: Green and Low-Carbon Economy, https://doi.org/10.47852/bonviewGLCE3202887

The Research Centre for Greenhouse Gas Innovation, which was created in 2016, in its last renewal in 2021, established the first nationwide nature-based solutions empirical data collection from the seven Brazilian biomes, on forestry, pasture, and agriculture, more specifically researching the role of agriculture for carbon sequestration and the possibilities to implement low emissions pastures.

Issue Brief: Defining Carbon Removal for Policy

Carbon Business Council, May 2023

Definitions of CDR in some policies to date have been incomplete and narrowly focused on specific CDR approaches. The Carbon Business Council strongly favors a clear and consistent definition of CDR for policy that is method neutral, criteria-based, and IPCC-aligned, to support the portfolio of CDR approaches that the world will need to meet our climate goals.

Sanchez et al. (2023): The Role of Direct Air Capture in EU’s Decarbonisation and Associated Carbon Intensity for Synthetic Fuels Production

Rocio Gonzalez Sanchez, Anatoli Chatzipanagi, Rocio Gonzalez Sanchez, Anatoli Chatzipanagi IN: Econ Papers, https://EconPapers.repec.org/RePEc:gam:jeners:v:16:y:2023:i:9:p:3881-:d:1138804

Given the high expectations placed on DAC for future decarbonisation, this study presents an extensive review of DAC technologies, exploring a number of techno-economic aspects, including an updated collection of the current and planned DAC projects around the world. A dedicated analysis focused on the production of synthetic methane, methanol, and diesel from DAC and electrolytic hydrogen in the European Union (EU) is also performed, where the carbon footprint is analysed for different scenarios and energy sources.
