Lefebvre, David; et al. (2020): Modelling the potential for soil carbon sequestration using biochar from sugarcane residues in Brazil

Lefebvre, David; Williams, Adrian; Meersmans, Jeroen; Kirk, Guy J. D.; Sohi, Saran; Goglio, Pietro; Smith, Pete (2020): Modelling the potential for soil carbon sequestration using biochar from sugarcane residues in Brazil. In Sci Rep 10 (1), p. 19479. DOI: 10.1038/s41598-020-76470-y.

"Sugarcane (Saccharum officinarum L.) cultivation leaves behind around 20 t ha−1 of biomass residue after harvest and processing. We investigated the potential for sequestering carbon (C) in soil with these residues by partially converting them into biochar (recalcitrant carbon-rich material)."

Guo, Rui; et al. (2020): Global CO2 uptake of cement in 1930–2019

Guo, Rui; Wang, Jiaoyue; Bing, Longfei; Tong, Dan; Ciais, Philippe; Davis, Steven J. et al. (2020): Global CO2 uptake of cement in 1930–2019. In Earth System Science Data. DOI: 10.5194/essd-2020-275.

"We adopted a comprehensive analytical model to estimate the amount of CO2 that had been absorbed from 1930 to 2019 in four types of cement materials including concrete, mortar, construction waste and cement kiln dust (CKD). Besides, the process CO2 emission during the same period based on the same datasets was also estimated."

Sekera, June; Lichtenberger, Andreas (2020): Assessing Carbon Capture: Public Policy, Science, and Societal Need

Sekera, June; Lichtenberger, Andreas (2020): Assessing Carbon Capture: Public Policy, Science, and Societal Need. In Biophys Econ Sust 5 (3), pp. 1–28. DOI: 10.1007/s41247-020-00080-5.

"Given the strong, if often unremarked, momentum of demands for public subsidy of these commercial methods, on what cogent bases can elected leaders make decisions that, first and foremost, meet societal needs? To address this question, we reviewed the scientific and technical literature on CDR, focusing on two methods that have gained most legislative traction: point-source capture and direct air capture–which together we term “industrial carbon removal” (ICR), in contrast to biological methods."

Honegger, Matthias; et al. (2020): Potential implications of carbon dioxide removal for the sustainable development goals

Honegger, Matthias; Michaelowa, Axel; Roy, Joyashree (2020): Potential implications of carbon dioxide removal for the sustainable development goals. In Climate Policy, pp. 1–21. DOI: 10.1080/14693062.2020.1843388.

"This review synthesizes the best available understandings of potential implications of CDR options aiming to complement emissions reductions. It seeks to identify effects on and interctions between specific social, environmental, and policy environments, in which various CDR options could be pursued. "

Bellamy, Rob; et al. (2021): Incentivising bioenergy with carbon capture and storage (BECCS) responsibly: Comparing stakeholder policy preferences in the United Kingdom and Sweden

Bellamy, Rob; Fridahl, Mathias; Lezaun, Javier; Palmer, James; Rodriguez, Emily; Lefvert, Adrian et al. (2021): Incentivising bioenergy with carbon capture and storage (BECCS) responsibly: Comparing stakeholder policy preferences in the United Kingdom and Sweden. In Environmental Science & Policy 116, pp. 47–55. DOI: 10.1016/j.envsci.2020.09.022.

"In this paper, we contend that BECCS must be incentivised responsibly, through policy-making processes which account for diverse and geographically varying societal values and interests. More specifically, we make the case for responsible incentivisation by undertaking a comparative analysis of stakeholder attitudes to four idealised policy scenarios for BECCS, including representatives of government, business, nongovernmental and academic communities, in the UK and Sweden."

Thoni, Terese; et al. (2020): Deployment of Negative Emissions Technologies at the National Level: A Need for Holistic Feasibility Assessments

Thoni, Terese; Beck, Silke; Borchers, Malgorzata; Förster, Johannes; Görl, Knut; Hahn, Alena et al. (2020): Deployment of Negative Emissions Technologies at the National Level: A Need for Holistic Feasibility Assessments. In Front. Clim. 2. DOI: 10.3389/fclim.2020.590305.

"We examine 17 Long-Term Low Greenhouse Gas Emission Development Strategies (LT-LEDS), and discuss them in the context of available NETs feasibility assessments. Our mapping shows that most countries include NETs in their long-term strategies, and that enhancement of natural sinks is the most dominating type of NET in these strategies."

Lockley, Andrew (2020): State commissioning of Solar Radiation Management geoengineering

Lockley, Andrew (2020): State commissioning of Solar Radiation Management geoengineering. In Ethics, Policy & Environment. DOI: 10.1080/21550085.2020.1848176.

"Notwithstanding concerns about privatisation, we assume state commissioning of SRM - proposing and analysing plausible governance, by adapting extant proposals. We consider two regulatory functions: legal/corporate; and scientific/technical. We briefly discuss mandatory, emissions-linked SRM funding."

Odoulami, Romaric C.; et al. (2020): Stratospheric Aerosol Geoengineering could lower future risk of ‘Day Zero’ level droughts in Cape Town

Odoulami, Romaric C.; New, Mark; Wolski, Piotr; Guillemet, Gregory; Pinto, Izidine; Lennard, Christopher et al. (2020): Stratospheric Aerosol Geoengineering could lower future risk of ‘Day Zero’ level droughts in Cape Town. In Environ. Res. Lett. 15 (12), p. 124007. DOI: 10.1088/1748-9326/abbf13.

"Here, we assess the potential for geoengineering using stratospheric aerosols injection (SAI) to offset the risk of 'Day Zero' level droughts in a high emission future climate using climate model simulations from the Stratospheric Aerosol Geoengineering Large Ensemble Project. Our findings suggest that keeping the global mean temperature at 2020 levels through SAI would offset the projected end century risk of 'Day Zero' level droughts by approximately 90%, keeping the risk of such droughts similar to today's level."

Schneider, Tapio; et al. (2020): Solar geoengineering may not prevent strong warming from direct effects of CO2 on stratocumulus cloud cover

Schneider, Tapio; Kaul, Colleen M.; Pressel, Kyle G. (2020): Solar geoengineering may not prevent strong warming from direct effects of CO2 on stratocumulus cloud cover. In Proceedings of the National Academy of Sciences of the United States of America. DOI: 10.1073/pnas.2003730117.

"Solar geoengineering that manipulates the amount of sunlight Earth absorbs is increasingly discussed as an option to counter global warming. However, we demonstrate that solar geoengineering is not a fail-safe option to prevent global warming because it does not mitigate risks to the climate system that arise from direct effects of greenhouse gases on cloud cover"
