Master’s thesis: Social Marginal Abatement Cost of Negative Emissions: Incorporating Externalities into the Private Costs of Carbon Dioxide Removal

Anna Havukainen, University of Helsinki, http://urn.fi/URN:NBN:fi:hulib-202404091663

The objective of this thesis was to identify the Negative Emission Technologies and Practices (NETPs) that yield the lowest social costs, thereby providing insights into which NETPs should be prioritized for investments in CDR. This evaluation was conducted by developing a Social Marginal Abatement Cost Curve (SMACC) framework, to examine the potentials and social costs of various NETPs.

Mwaura et al. (2024): Do smallholders have a role to play in atmospheric greenhouse gas removal? Insights from western Kenya

Francis M. Mwaura, Margaret W. Ngigi, Gideon Obare IN: Scientific African 24, e02206, https://doi.org/10.1016/j.sciaf.2024.e02206

Despite consensus by the international community on the need for setting targets for reducing emissions or enhancing removal of greenhouse gases, comprehensive strategies for enumerating smallholders’ roles are yet to be designed and tested. Moreover, although smallholders’ role as net greenhouse gas removers has been speculated, evidence of this fact is necessary. A survey of 380 smallholders involved in maize-farming system in four sub-counties of western Kenya representing heterogeneity in agro-ecological zones and postulated biomass cooking energy access and demand was undertaken.

Otto & Matzner (2024): Let Us Get Regional: Exploring Prospects for Biomass-Based Carbon Dioxide Removal on the Ground

Danny Otto, Nils Matzner IN: C 10, 25, https://doi.org/10.3390/c10010025

Regional case studies investigating the dynamics that may facilitate or impede the broader adoption of CDR methods in spatially explicit settings are critically absent. Understanding implementation contexts on the ground is vital, and comparing them across different removal methods is essential for effectively scaling up CDR. This paper aims to address this research gap by comparatively examining the development of biomass-based CDR in three regions of Germany. Taking an exploratory approach, we conducted surveys in these regions to gain insight into stakeholder perceptions of six CDR methods.

Chapter: Markus & Schaller (2024): Land-Use Implications of Carbon Dioxide Removal: An Emerging Legal Issue?

Till Markus, Romina Schaller IN: Ginzky, H., et al. International Yearbook of Soil Law and Policy 2022. Springer, Cham. https://doi.org/10.1007/978-3-031-40609-6_5

Science has expressed concerns that CDR as a means to fight climate change could potentially increase competition for land and contribute to soil degradation. This paper aims to map out the potential land-use and soil implications of CDR to identify possible lines of political and legal conflicts.

Singh & De (2024): Carbon Dioxide Removal by Chemically and Thermally Reduced Graphene-Based Adsorbents

Sohan Bir Singh, Mahuya De IN: Korean Journal of Chemical Engineering 41, 783-796, https://doi.org/10.1007/s11814-024-00111-7

In this study, few layers (7–9) graphene adsorbents, prepared by chemical and thermal reduction techniques, were investigated for CO2 adsorption. The study showed the effect of graphene structures on CO2 removal at three different temperatures (0, 25, and 50 °C) and in pressure range of 0–5 bar.

Nature – Baum et al. (2024): Public perceptions and support of climate intervention technologies across the Global North and Global South

Chad M. Baum, Livia Fritz, Sean Low, Benjamin K. Sovacool IN: Nature Communications 15, 2060, https://doi.org/10.1038/s41467-024-46341-5

Novel, potentially radical climate intervention technologies like carbon dioxide removal and solar geoengineering are attracting attention as the adverse impacts of climate change are increasingly felt. The ability of publics, particularly in the Global South, to participate in discussions about research, policy, and deployment is restricted amidst a lack of familiarity and engagement. Drawing on a large-scale, cross-country exercise of nationally representative surveys in 30 countries and 19 languages, this article establishes the first global baseline of public perceptions of climate-intervention technologies.

Webinar: Scrubbing the Skies -Geologic Sequestration of Carbon Dioxide: The State of Responsible Primacy

March 25, 12-1 pm CST, hosted by the Institute for Responsible Carbon Removal

Industrial carbon capture and carbon dioxide removal are important strategies to reach global and national net zero CO2 emissions targets and to keep global temperatures at or below 1.5°C. The most common setting for permanently sequestering CO2 after it has been captured is underground, in very deep, impermeable rock formations. To regulate and monitor the sequestered CO2, the US Environmental Protection Agency (EPA) is charged with administering the Underground Injection Control (UIC) program, whereby it sets regulatory standards and processes applications for underground wells with the goal of preventing contamination of drinking water under the Safe Drinking Water Act. A new issue brief from the National Wildlife Federation – Geologic Sequestration of Carbon Dioxide: The State of Responsible Primacy – examines the question of who should have authority over carbon storage wells: states or the federal government, an issue known as “primacy.” It includes details on what it takes to successfully permit a carbon storage well, why the federal government has encouraged states to apply for primacy, and how states like North Dakota, Wyoming, and Louisiana came to acquire primacy. The panelists, Jake Ferrell and Dr. Simone H. Stewart, will discuss their recommendations for ensuring primacy is done responsibly, with an emphasis on environmental justice and community engagement.

Licentiate thesis: Modeling the Potential for Carbon Removal in Agriculture: Integrating Farmer Perspectives

Andreas Rehn, Chalmers Universtiy of Technology

The overarching aim of this thesis is to provide insights into the dynamic processes governing SOC stocks and to identify viable paths for agricultural systems to contribute to climate change mitigation. By integrating current scientific knowledge of carbon sequestration in agriculture with feasible agricultural applications, this work proposes local realistic strategies for enhancing soil organic carbon and presents a quantitative assessment of their potential for CO2 removal.

Removing carbon dioxide from the atmosphere

by Juliane El Zohbi and Diana Rechid on openaccessgovernment.org, January 9th, 2024

“The agricultural sector plays a decisive role in tackling climate change. GERICS explores what actors of the agricultural sector think of removing carbon dioxide and what support they need from science.”
