mCDR Foresight Scenarios: Policy Frameworks for Marine Carbon-Dioxide Removal in 2040

Miranda Böttcher, Working Paper Research Division EU/Europe 2023/No. 02, April 2023, 35 Pages

This report outlines processes and insights from a participatory foresight workshop held in Berlin (December 2022). This workshop aimed to switch the mode of thinking about the future of mCDR policy from predictive to anticipatory: a reorientation from »navigating ‘what will be’« to »thinking through alternative ‘what ifs?’« The workshop organisers aimed to encourage the participants to engage experimentally with conceptions of the future derived from a broad field of perspectives. Additionally, the workshop was designed to help the participants explore the capacities of various policy frameworks and instruments to deal with threats and opportunities across a range of plausible futures.

Prado & Dowell (2023): The cost of permanent carbon dioxide removal

Augustin Prado and Niall Mac Dowell IN: Joule 7, 700–712; https://doi.org/10.1016/j.joule.2023.03.006

In this contribution, the authors present a general analytical framework that quantifies the non-zero climate repair value (CRV) of a CDR pathway of arbitrary permanence. A non-linear relationship between store durability and CRV is observed. The authors then incorporate the CRV concept in a conventional levelized cost of removal analysis, extended to account for monitoring, reporting, and verification (MRV) of a given store.

Kerner et al. (2023): Carbon dioxide removal to combat climate change? An expert survey on perception and support

Christoph Kerner, Annina Thaller and Thomas Brudermann IN: Environmental Research Communications, DOI 10.1088/2515-7620/accc72 

This study provides insights into academic expert opinions about Bioenergy with Carbon Capture and Storage (BECCS) and Direct Air Carbon Capture and Storage (DACCS). An online survey was conducted to examine how academic experts (N = 172) perceive and to what extent they support BECCS and DACCS.

Call for Applications: Carbon Removal Justice Fellows Program

Deadline for applications: May 20, 2023

Two-week Fellows Program will run from July 10-24, 2023

The National Wildlife Federation and the Institute for Carbon Removal Law and Policy at American University invite applicants for the inaugural cohort of the Carbon Removal Justice Fellows Program („the Fellows Program“). It is designed to bring environmental justice voices and perspectives into the fast-developing field of carbon removal policy, research, and private sector activity. The Fellows Program will:

  • Provide participants with an introduction to the field of carbon removal, centering environmental justice considerations and concerns;
  • Include conversations with key figures in U.S. federal policymaking, the private sector, and civil society; and
  • Involve site visits to two U.S. locations grappling with decisions around carbon removal. 

They invite applications from people who work with or in environmental justice organizations, who represent frontline climate communities, or who have a strong background in environmental justice-oriented organizing and practice. The Fellows Program will provide up to ten participants with a two-week introduction to the field. In addition, one participant will take up a full-time 11-month position with the National Wildlife Federation and work closely with staff at the Institute for Carbon Removal Law and Policy. Applicants should identify whether they are applying for the two-week fellowship, the 11-month opportunity with the National Wildlife Federation, or both.

Ayuba & Oruonye (2023): Potentials of Nature-Based Solutions to Climate Change Mitigation in Nigeria

H.K. Ayuba, E.D. Oruonye IN: Social Science, Humanities and Sustainability Research, https://doi.org/10.22158/sshsr.v4n1p45

There is need to explore alternative strategy of climate change mitigation in Nigeria. Nature based climate solution offers opportunity of a more practicable, cheap, and implementable alternative to reducing GHG emissions. The study was carried out through desk review of existing literatures, complimented by interview of key stakeholders.

Running Tide: Framework Protocol for open ocean carbon removal

by Brad Rochlin on runningtide.com; 19.4.2023

Running Tide shares their initial Framework Protocol for open ocean carbon removal. The document details the high-level framework used to quantify the net carbon removed via our multi-pathway carbon removal system. This protocol is the culmination of many years of work across cross-functional team of scientists, engineers, maritime operators, and carbon market experts, and has garnered and integrated feedback from leading experts across more than 25 carbon removal, oceanographic, environmental, and climate organizations.

Wong et al.(2023): Short-term effects of increasing compost application rates on soil C and greenhouse gas (N2O and CO2) emissions in a California central coast vineyard

Connie T. F. Wong, Mia Falcone, Geovan Rich, Craig Stubler, Bwalya Malama, Cristina Lazcano, Charlotte Decock IN: Frontiers in Environmental Science, https://doi.org/10.3389/fenvs.2023.1123510

A 2-year field experiment in a Mediterranean vineyard on the California Central Coast was conducted to investigate the short-term effects of compost application at four different rates on soil C dynamics and greenhouse gas emissions. Two years of greenhouse gas sampling were performed using static chambers at vineyard management events in two functional locations (tractor row and under the vines). Soil samples were collected annually in spring at the same locations at 0–15, 15–30 and 30–60 cm depth, and during greenhouse gas sampling at 0–15 cm.

Shi et al. (2023): Review on Multidimensional Adsorbents for CO2 Capture from Ambient Air: Recent Advances and Future Perspectives

Yihan Shi, Ruiyan Ni, Yi Zhao IN: Energy & Fuels, https://doi.org/10.1021/acs.energyfuels.3c00381

Solid porous sorbents have drawn increasing attention for CO2 capture from the atmosphere with ultralow CO2 concentration (ca. 400 ppm). However, most related studies focus on nanoparticle-based adsorbents and their functionalized counterparts, which are more prone to lose weight in the atmosphere. In this context, the authors summarize nanoparticle composite adsorbents, including zero-dimensional powders, one-dimensional fibers, two-dimensional membranes, and three-dimensional aerogels, and assess the physicochemical properties and typical applications of major types of nanoporous adsorbents in the field of CO2 adsorption and separation with emphasis on DAC.

Buch: Warnsignal Klima – Hilft Technik gegen die Erderwärmung?

Hrsg. J.L.Lozán, H. Graßl, S.-W. Breckle, D. Kasang & M. Quante (2023), 332 Seiten

Es gibt zahlreiche Verfahren, mit denen CO2 aus der Atmosphäre entfernt werden kann, um neben der absolut vorrangigen Emissionsminderung Neto-Null-Emissionen zu erreichen. In diesem zusammenfassenden Buch wird der potenzielle Beitrag verschiedener Methoden vorgestellt. Neben CDR-Methoden und denen des Strahlungsmanagements (radiation management, RM) werden auch Methoden der CO2-Nutzung und sowie der Dekarbonisierung in der Industrie behandelt. Diese Informationen aus der Wissenschaft in rund 50 allgemeinverständlichen Artikeln stammen von rund 70 Fachleuten aus verschiedenen Instituten in Deutschland und benachbarten Ländern. Das Buch wendet sich nicht nur an Studierende, Lehrer, Schüler und interessierte Laien, sondern auch an Entscheidungsträger und Behörden.
