Nature – Qiu et al. (2022): Environmental trade-offs of direct air capture technologies in climate change mitigation toward 2100

Yang Qiu, Patrick Lamers, Vassilis Daioglou, Noah McQueen, Harmen-Sytze de Boer, Mathijs Harmsen, Jennifer Wilcox, André Bardow & Sangwon Suh IN: Nat Commun 13, 3635 (2022). https://doi.org/10.1038/s41467-022-31146-1

Direct air capture (DAC) is critical for achieving stringent climate targets, yet the environmental implications of its large-scale deployment have not been evaluated in this context. Performing a prospective life cycle assessment for two promising technologies in a series of climate change mitigation scenarios, the authors find that electricity sector decarbonization and DAC technology improvements are both indispensable to avoid environmental problem-shifting.

Ocean Carbon Conference

Thu, 14 July 2022; 10:00 – 16:00 BST by Centre for Climate Repair at Cambridge

A one day hybrid conference on ocean carbon sequestration: Marine Biomass Regeneration (MBR) is a project to regenerate biomass in the oceans and not only thereby support marine ecosystems but also enhance the drawdown CO2 from the atmosphere. The objective of the project is to emulate the role of whales which feed in the benthic waters and return to the surface to defecate. The natural biological pumping and recycling of nutrients to the surface ocean is therefore diminished.

Damartzis et al. (2022): Solvents for Membrane-Based Post-Combustion CO2 Capture for Potential Application in the Marine Environment

Theodoros Damartzis, Akrivi Asimakopoulou, Dimitrios Koutsonikolas, George Skevis, Chara Georgopoulou, George Dimopoulos, Lampros Nikolopoulos, Konstantinos Bougiouris , Hannes Richter ,Udo Lubenau, Solon Economopoulos, Cristina Perinu, David Hopkinson, Grigorios Panagakos IN: Appl. Sci. 12(12), 6100; https://doi.org/10.3390/app12126100

In this paper, the authors present an comprehensive review of the different solvents that can be used for post-combustion CO2 capture on-board ships. Furthermore, they investigated the solvents’ performance as determined by their inherent characteristics, properties, and behavior for a range of operating conditions against the strict shipping requirements.

Silva et al. (2022): A generalizable framework for enhanced natural climate solutions

Lucas C. R. Silva, Mary C. Wood, Bart R. Johnson, Michael R. Coughlan, Heather Brinton, Krista McGuire, Scott D. Bridgham IN: Plant Soil (2022). https://doi.org/10.1007/s11104-022-05472-8

Different land-use sectors compete for resources and incentives within and across geopolitical regions, resulting in divergent goals and inefficient prioritization of CO2 removal efforts. The authors propose a generalizable framework for Enhanced Natural Climate Solutions (NCS +), which they define as activities that can be coordinated to increase carbon drawdown and permanence on land while improving livelihoods and the provision of natural resources in vulnerable communities and ecosystems.

Christianson et al. (2022): The Promise of Blue Carbon Climate Solutions: Where the Science Supports Ocean-Climate Policy

Anne B. Christianson, Anna Cabré, Blanca Bernal, Stacy K. Baez, Shirley Leung, Alicia Pérez-Porro and Elvira Poloczanska IN: Front. Mar. Sci., https://doi.org/10.3389/fmars.2022.851448

This paper gives context to numerous blue carbon sequestration pathways, quantifying their potential to sequester carbon from the atmosphere, and comparing these sequestration pathways to point-source emissions reductions. The applicability of blue carbon is then discussed in terms of multiple international policy frameworks, to help individuals and institutions utilize the appropriate framework to reach ocean conservation and climate mitigation goals.

GESAMP and C2G’s virtual joint side event: ‚Marine Cloud Brightening, a governance dilemma‘ 

Friday 1 July at 11:00-12:15 WEST (10:00-11:15 UTC) (UN Ocean Conference)

The Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection (GESAMP) and the Carnegie Climate Governance Initiative (C2G) will co-organize a virtual side event on „Marine Cloud Brightening- a governance dilemma“. The event will feature a panel of global speakers with diverse expertise on the ocean, climate change, environmental and ocean law and governance, to engage in discussions on the governance of Marine Cloud Brightening.
