IPCC (2024): Report of the Expert Meeting on Carbon Dioxide Removal Technologies and Carbon Capture, Utilization and Storage

IPCC, Eds: Enoki, T., Hayat, M, Pub. IGES, 2024

With the emergence of new carbon dioxide removal technologies and the generation of new empirical data on relevant sources and sinks, it may be valuable to consider new methods in the IPCC Guidelines. If adopted, these new methods will broaden the base of sinks and sources that inventory compilers should routinely monitor and facilitate their estimation and reporting in future national inventories. With this context in mind, the IPCC tasked the Task Force on National Greenhouse Gas Inventories (TFI), in January 2024, to develop a Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture Utilisation and Storage activities (Decision IPCC-LX- 9). An Expert Meeting on this topic was also mandated by the IPCC and held in Vienna on 1-3 July 2024. This was the first step along the journey to prepare the Methodology Report and this document is a Report of that Meeting.

Kreuzburg et al. (2024): Unified Assessment framework for proposed methods of MarineCDR and interim knowledge Synthesis

Kreuzburg, M., Baatz, C., Bednarz, L., Böttcher, M., Merk, C., Morganti, T., Tank, L., Yao, W. B., Wehnert, H., Rehder, G. IN: ASMASYS, DOI 10.3289/CDRmare.37

In ASMASYS, one of the main goals is to establish a comprehensive assessment framework for marine carbon dioxide removal (mCDR) and marine carbon storage (mCS) options, serving as a foundational tool for evaluating various methods uniformly.
A standardized assessment process promotes transparency, accountability and public trust in mCDR/mCS initiatives and facilitates informed dialogue and stakeholder engagement. Overall, the creation of an assessment framework is critical to the responsible development and implementation of
mCDR and storage methods, balancing the potential benefits with the need to minimize environmental and social risks.

Europe and Germany’s Role in Catalyzing aTrillion-Euro Industry

Patrick Herhold, Johanna Pütz, Karan Mistry, Robin Bierganz, Phillip Spiekermann, Louisa Maier, German Association for Negative Emissions (DVNE) & Boston Consulting Group (BCG), June 2024

This report has three objectives:

  • The primary objective is to explore and demonstrate the economic potential of carbon dioxide removal (CDR), specifically for Europe and Germany.
  • Additionally, the report aims to provide a comprehensive overview of the quickly evolving CDR landscape while distinguishing CDR from other related concepts.
  • Lastly, the report emphasizes the need for swift and decisive action by providing a specific, stakeholder-oriented action plan to realize the economic potential outlined.

El Zohbi et al. (2024): Engaging Stakeholders in Your Carbon Dioxide Removal Research. Reflection Paper with Learnings & Recommendations from the CDRterra research programme

Juliane El Zohbi, Lukas Fehr, Samuel Eberenz, Danny Otto, Diana Rechid, Marcos Jiménez Martínez, Fernando-Esteban Montero-de-Oliveira, Felix Gulde, Lara Bartels, Maximilian Witting, Nils Matzner, Sabine Reinecke, Samuel Fischer, Veronika Strauss, June 10, 2024

Carbon Dioxide Removal (CDR) is a growing field that is getting more and more attention from a variety of stakeholders across science, economy, politics, Non-Governmental Organizations (NGOs) etc. We understand stakeholders as persons, groups and organizations that are affected by or influence a (research) topic. This interest often brings together different stakeholders to acquire basic knowledge, build networks or advocate for shared interests. Here, we do not go deeper into the “why” of stakeholder engagement in research – this is sufficiently presented in literature and frameworks for transdisciplinary and responsible research and innovation (e.g., Stilgoe et al., 2013; Bammer, 2013). Instead, we reflect on the multitudes of “whats” and “hows” of CDR-related stakeholder engagement we encountered in the research programme CDRterra. The 10 consortia within CDRterra engaged with stakeholders in many different ways. Here, we share our experiences and reflections as well as synthesize learnings on how best to proceed – for researchers already engaging with stakeholders or planning to involve stakeholders in upcoming CDR-related projects.

The State of Carbon Dioxide Removal: A global independent scientific assessment of Carbon Dioxide Removal, 2nd edition

Stephen M. Smith, Oliver Geden, Matthew J. Gidden, William F. Lamb, Gregory F. Nemet, Jan C. Minx, Holly Buck, Josh Burkev, Emily Cox, Morgan R. Edwards, Sabine Fuss, Injy Johnstone, Finn Müller-Hansen, Julia Pongratz, Benedict S. Probst, Stephanie Roe, Felix Schenuit, Ingrid Schulte, Naomi E. Vaughan, University of Oxford’s Smith School of Enterprise, June 4, 2024

Although the Paris Agreement states that climate change mitigation must be done “in the context of sustainable development”, most scenarios do not explicitly consider social and environmental sustainability. The authors therefore identified a subset of scenarios that can be considered “more sustainable”. Across this group of scenarios, the central range of CDR deployment is 7 to 9 GtCO2 per year in 2050. The lowest scenarios reach 4 GtCO2 per year in 2050. While this range is similar in 2050 to that for all below 2°C scenarios, the more sustainable scenarios cumulatively remove 170 GtCO2 between 2020 and the time of net zero CO2, compared with 260 GtCO2 cumulatively in all below 2°C scenarios.

Global Climate: Chemistry of CO2 Removal

Lauren J. Barrett, Samantha Rush, Penny Vlahos, ACS Publications, June 2024

The reader is introduced to the underlying physics of Earth’s energy systems, an outline of the global carbon cycle and its effects on climate over various timescales, and the theory of CDR. Understanding the natural relationship between carbon cycles and global climate is essential to CDR, as most technologies strive to accelerate the long-term carbon storage mechanisms provided in nature. To that end, a bottom-up understanding of atmospheric energy budgets from greenhouse gases to millennial-scale carbon cycling is provided.

Ashes to ashes, carbon to soil: A cost-benefit analysis of abatement measures to increase soil carbon-sequestration capacity

Markus Zimmer, Arne Holzhausen, Francesco Iezzi, Haki Pamuk, Marcia Arredondo Rivera, Jurrian Nannes, Maria Naranjo Barrantes, Nico Polman, Willem-Jan van Zeist, Allianz, April 30, 2024

This study examines five soil improvement measures — three crop management practices (cover cropping, no tillage and use of green manure) and two broader land restoration techniques (agroforestry and sustainable forest management) — that can enhance soil quality, in six countries: Germany, France, the Netherlands, Italy, Spain and the UK. All these measures contribute to preventing soil erosion, enhancing carbon sequestration, and improving biodiversity.

Carbon Dioxide Removal (CDR) 2024-2044: Technologies, Players, Carbon Credit Markets, and Forecasts

Eve Pope, ITTechEx Research, April 2024

This report provides a comprehensive outlook of the emerging CDR industry and carbon credit markets, with an in-depth analysis of the technological, economic, regulatory, and environmental aspects that are shaping this market. In it, IDTechEx focuses on technologies that actively draw CO₂ from the atmosphere and sequester it into carbon sinks, namely: Direct air carbon capture and storage (DACCS), Biomass with carbon removal and storage (BiCRS) including approaches such as BECCS (bioenergy with carbon capture and storage), biochar, biomass burial, and bio-oil underground injection, Land-based CDR methods, i.e. afforestation and reforestation and soil carbon sequestration techniques, Mineralization NETs that enhance natural mineral processes and Ocean-based CDR methods.

The Landscape of Carbon Dioxide Removal and US Policies to Scale Solutions

Whitney Jones, Galen Bower, Nathan Pastorek, Ben King, John Larsen, Trevor Houser, Naveen Dasari, Kelly McCusker, Rhodium Group, April 20, 2024

In this report, the authors survey the current and vast landscape of different CDR approaches in the US, informed by the latest peer-reviewed literature, dozens of expert interviews, and new analysis. They also assess the current state of policy support and additional policy options to help CDR scale to the level required for mid-century decarbonization in the US.
