Gardiner, S.; et al. (2019): Geoengineering, Political Legitimacy and Justice

Gardiner, S.; Fragnière, A. (2019): Geoengineering, Political Legitimacy and Justice. In: Ethics, Policy & Environment 21 (3), S. 265–269. DOI: 10.1080/21550085.2018.1562524.

"Technologies which might be deployed to attempt geoengineering are either speculative or only in the very early stages of development. [...] Despite their speculative nature, discussion of geoengineering technologies is growing rapidly in science and policy circles. Having for decades largely been dismissed as irrelevant or counterproductive to serious discussion, some now advocate for geoengineering techniques as possible ‘tools in the toolkit’ for future climate action.

Heyen, D.; et al. (2019): Strategic implications of counter-geoengineering: Clash or cooperation?

Heyen, D.; Horton, J.; Moreno-Cruz, J. (2019): Strategic implications of counter-geoengineering. Clash or cooperation? In: Journal of Environmental Economics and Management. DOI: 10.1016/j.jeem.2019.03.005.

"Solar geoengineering has received increasing attention as an option to temporarily stabilize global temperatures. A key concern is that heterogeneous preferences over the optimal amount of cooling combined with low deployment costs may allow the country with the strongest incentive for cooling, the so-called free-driver, to impose a substantial externality on the rest of the world. We analyze whether the threat of counter-geoengineering technologies capable of negating the climatic effects of solar geoengineering can overcome the free-driver problem and tilt the game in favor of international cooperation."

Renforth, P. (2019): The negative emission potential of alkaline materials

Renforth, P. (2019): The negative emission potential of alkaline materials. In: Nat Comms 10 (1), S. 1401. DOI: 10.1038/s41467-019-09475-5.

"7 billion tonnes of alkaline materials are produced globally each year as a product or by-product of industrial activity. [...] Here we show that these materials have a carbon dioxide storage potential of 2.9–8.5 billion tonnes per year by 2100, and may contribute a substantial proportion of the negative emissions required to limit global temperature change to <2 °C."

Viglizzo, E. F.; et al. (2019): Reassessing the role of grazing lands in carbon-balance estimations. Meta-analysis and review

Viglizzo, E. F.; Ricard, M. F.; Taboada, M. A.; Vázquez-Amábile, G. (2019): Reassessing the role of grazing lands in carbon-balance estimations. Meta-analysis and review. In: The Science of the Total Environment 661, S. 531–542. DOI: 10.1016/j.scitotenv.2019.01.130.

"Assuming a steady state between carbon (C) gains and losses, greenhouse gases (GHG) inventories that follow a widely used simplified procedure (IPCC Tier 1) tend to underestimate the capacity of soils in grazing-land to sequester C. In this study we compared the C balance reported by (i) national inventories that followed the simplified method (Tier 1) of IPCC (1996/2006), with (ii) an alternative estimation derived from the meta-analysis of science-based, peer-reviewed data."

Fasihi, M.; et al. (2019): Techno-economic assessment of CO2 direct air capture plants

Fasihi, M.; Efimova, O.; Breyer, C. (2019): Techno-economic assessment of CO2 direct air capture plants. In: Journal of Cleaner Production. DOI: 10.1016/j.jclepro.2019.03.086.

"CO2 direct air capture (DAC) has been increasingly discussed as a climate change mitigation option. Despite technical advances in the past decade, there are still misconceptions about DAC's current and long-term costs as well as energy, water and area demands. This could undermine DAC's anticipated role in a neutral or negative greenhouse gas emission energy system, and influence policy makers. In this study, a literature review and techno-economic analyses of state-of-the-art DAC technologies are performed, wherein, DAC technologies are categorised as high temperature aqueous solutions (HT DAC) and low temperature solid sorbent (LT DAC) systems, from an energy system perspective."

Reith, F.; et al. (2019): Meeting climate targets by direct CO2 injections. What price would the ocean have to pay?

Reith, F.; Koeve, W.; Keller, D.; Getzlaff, J.; Oschlies, A. (2019): Meeting climate targets by direct CO2 injections. What price would the ocean have to pay? In: Earth Syst. Dynam. Discuss., S. 1–29. DOI: 10.5194/esd-2018-87.

"We investigate the climate mitigation potential and collateral effects of direct injections of captured CO2 into the deep ocean as a possible means to close the gap between an intermediate CO2 emissions scenario and a specific temperature target, such as the 1.5 °C target aimed for by the Paris Agreement. For that purpose, a suite of approaches for controlling the amount of direct CO2 injections at 3000 m water depth are implemented in an Earth System Model of intermediate complexity."

Blocka, M.; et al. (2019): A new chapterShifting Poland towards net-zero economy

Blocka, M.; Sniegocki, A.; Porebna, K.; Wetmanska, Z.; Bukowski, M. (ed.) (2019): A new chapterShifting Poland towards net-zero economy. Online: http://wise-europa.eu/wp-content/uploads/2019/03/New_chapter_Poland_net-zero-1.pdf.

"This report aims to demonstrate that without a bold new vision of changes in all key sectors of the economy, Poland will spend the decades to come among Euope's climate laggards, incurring the associated costs and losing subsequent development opportunities in the emerging low-carbon goods and services markets."

Haikola, S.; et al. (2019): From polarization to reluctant acceptance–bioenergy with carbon capture and storage (BECCS) and the post-normalization of the climate debate

Haikola, S.; Hansson, A.; Anshelm, J. (2019): From polarization to reluctant acceptance–bioenergy with carbon capture and storage (BECCS) and the post-normalization of the climate debate. In: Journal of Integrative Environmental Sciences 74, S. 1–25. DOI: 10.1080/1943815X.2019.1579740.

"The paper covers the public debate on BECCS (bioenergy with carbon capture and storage) between 2008 and 2018. Through a qualitative analysis of around 800 feature articles, editorials, and opinion pieces published in English, German, Swedish, Danish, and Norwegian in news media and debates sections of scientific media, we highlight conspicuous aspects of the debate and relate them to the theoretical concept of post-normal science. We find that the debate is characterized by an emphasis on values, scientific uncertainty and the integrity of science, premised on a pervading sense of urgency."

Kaya, Y.; et al. (2019): Towards net zero CO2 emissions without relying on massive carbon dioxide removal

Kaya, Y.; Yamaguchi, M.; Geden, O. (2019): Towards net zero CO2 emissions without relying on massive carbon dioxide removal. In: Sustain Sci 354 (5), S. 182. DOI: 10.1007/s11625-019-00680-1.

"Current emission scenarios that allow keeping the global temperature increase below 2 °C or even 1.5 °C—as foreseen by the Paris Agreement—are based on very optimistic assumptions, including enormous volumes of carbon dioxide removal (CDR). A closer look at the globally most important emission sectors—power, transport and industry—shows manifold barriers for very ambitious mitigation."

Erans, M.; et al. (2019): Pilot-scale calcination of limestone in steam-rich gas for direct air capture

Erans, M.; Nabavi, S.; Manović, V. (2019): Pilot-scale calcination of limestone in steam-rich gas for direct air capture. In: Energy Conversion and Management: X, S. 100007. DOI: 10.1016/j.ecmx.2019.100007.

"A novel polygeneration concept, which has been proposed recently, comprises a fuel-cell calciner integrated system in order to produce electricity and lime which can be used for direct air capture (DAC) to remove CO2 from the atmosphere. [...] Moreover, increasing steam concentration during calcination affected the material performance and DAC capacity at ambient conditions positively. Therefore, these findings demonstrate that limestone calcined under typical SOFC afterburner exhaust conditions is suitable as a DAC sorbent."
