Coalition for Negative Emissions: World will miss climate targets without introduction of large-scale negative emissions solutions by 2025

"Study shows negative emissions solutions including BECCS, DACS and NCS are all proven and can each provide at least 1Gt of sustainable negative emissions."

McKinsey Sustainability: How negative emissions can help organizations meet their climate goals

"Substantial negative emissions (carbon removals) are needed with emission reductions to avert catastrophic climate change. Analysis shows that negative emissions can be deployed at the required scale."

Zickfeld, Kirsten; et al. (2021): Asymmetry in the climate–carbon cycle response to positive and negative CO2 emissions

Zickfeld, Kirsten; Azevedo, Deven; Mathesius, Sabine; Matthews, H. Damon (2021): Asymmetry in the climate–carbon cycle response to positive and negative CO2 emissions. In Nat. Clim. Chang., pp. 1–5. DOI: 10.1038/s41558-021-01061-2.

" It is commonly assumed that the climate–carbon cycle response to a negative CO2 emission is equal in magnitude and opposite in sign to the response to an equivalent positive CO2 emission. Here we test the hypothesis that this response is symmetric by forcing an Earth system model with positive and negative CO2 emission pulses of varying magnitude and applied from different climate states."

Belmonte, Beatriz A.; et al. (2021): A fuzzy optimization model for planning integrated terrestrial carbon management networks

Belmonte, Beatriz A.; Aviso, Kathleen B.; Benjamin, Michael Francis D.; Tan, Raymond R. (2021): A fuzzy optimization model for planning integrated terrestrial carbon management networks. In Clean Techn Environ Policy, pp. 1–13. DOI: 10.1007/s10098-021-02119-7.

"Although recent papers have reported the development of process integration models for optimizing carbon management networks based on either biochar application or enhanced weathering, none have reported models integrating these two NETs in the same system. To address this gap, a fuzzy mixed-integer linear programming model is developed that integrates biochar application and enhanced weathering for large-scale carbon sequestration."

Tan, Raymond R.; et al. (2021): Pinch-based planning of terrestrial carbon management networks

Tan, Raymond R.; Aviso, Kathleen B.; Bandyopadhyay, Santanu (2021): Pinch-based planning of terrestrial carbon management networks. In Cleaner Engineering and Technology 4, p. 100141. DOI: 10.1016/j.clet.2021.100141.

"In this work, a pinch analysis approach for the planning of CMNs based on either enhanced weathering or biochar application is developed."

Fuhrman, Jay; et al. (2021): The role of negative emissions in meeting China’s 2060 carbon neutrality goal

Fuhrman, Jay; Clarens, Andres F.; McJeon, Haewon; Patel, Pralit; Ou, Yang; Doney, Scott C. et al. (2021): The role of negative emissions in meeting China’s 2060 carbon neutrality goal. In Oxford Open Climate Change 1 (1). DOI: 10.1093/oxfclm/kgab004.

"We use the Global Change Analysis Model to simulate how negative emissions technologies, in general, and direct air capture (DAC) in particular, could contribute to China’s meeting this target."

Palmer, James; Carton, Wim (2021): Carbon Removal as Carbon Revival? Bioenergy, Negative Emissions, and the Politics of Alternative Energy Futures

Palmer, James; Carton, Wim (2021): Carbon Removal as Carbon Revival? Bioenergy, Negative Emissions, and the Politics of Alternative Energy Futures. In Front. Clim. 3, p. 60. DOI: 10.3389/fclim.2021.678031.

"This Perspective therefore calls for governance frameworks for carbon dioxide removal to adjudicate between conflicting approaches to achieving negative emissions not only on the basis of technical efficiency, or even ‘on-the-ground’ social and environmental impacts, but also according to compatibility with socially legitimate visions and understandings of what energy – and more specifically energy use – should ultimately be for in the post-fossil fuel era."

Job: Postdoctoral Associate (Stony Brook University)

Deadline: 19. June 2021

"Seeking a postdoc familiar with the marine carbonate system for an interdisciplinary project in the emerging field of ocean carbon dioxide removal (ocean CDR) and negative emissions technologies (NETs) that aims to mitigate ocean acidification while decreasing the atmospheric carbon dioxide concentration. The postdoc will help evaluate an electrochemical process that enables local adjustment and control of seawater carbonate chemistry."

Lenzi, Dominic (2021): On the Permissibility (Or Otherwise) of Negative Emissions

Lenzi, Dominic (2021): On the Permissibility (Or Otherwise) of Negative Emissions. In Ethics, Policy & Environment, pp. 1–14. DOI: 10.1080/21550085.2021.1885249.

"While NETs are not risk-free, I argue that they could be part of minimally just responses to climate change. In doing so, I identify a dilemma between limiting warming to 1.5 ° C, which promises lower climate impacts but implies greater NETs risks, and 2°C, which requires less NETs but promises greater climate impacts. Finally, I consider what the case of NETs reveals about permissibility in the face of non-compliance with principles of climate justice."
