Melara, A. Jasmin; et al. (2020): Is aquatic bioenergy with carbon capture and storage a sustainable negative emission technology? Insights from a spatially explicit environmental life-cycle assessment.

Melara, A. Jasmin; Singh, Udayan; Colosi, Lisa M. (2020): Is aquatic bioenergy with carbon capture and storage a sustainable negative emission technology? Insights from a spatially explicit environmental life-cycle assessment. In Energy Conversion and Management 224, p. 113300. DOI: 10.1016/j.enconman.2020.113300.

"[T]his study applies life-cycle assessment (LCA) incorporating a geographic information system (GIS) framework to estimate the environmental impacts of A-BECCS over all stages of its life-cycle."

Morton, Evvan V. (2020): Reframing the Climate Change Problem: Evaluating the Political, Technological, and Ethical Management of Carbon Dioxide Emissions in the United States

Morton, Evvan V. (2020): Reframing the Climate Change Problem: Evaluating the Political, Technological, and Ethical Management of Carbon Dioxide Emissions in the United States. Doctoral Dissertation. Arizona State University. Available online at https://repository.asu.edu/items/57290.

"Although research also confirms that negative emission technologies (NETs) are necessary to stay within 1.5-2°C of global warming, this dissertation proposes that the climate change problem has been ineffectively communicated to suggest that CO2 emissions reduction is the only solution to climate change."

Brack, Duncan; King, Richard (2020): Managing Land‐based CDR: BECCS, Forests and Carbon Sequestration

Brack, Duncan; King, Richard (2020): Managing Land‐based CDR: BECCS, Forests and Carbon Sequestration. In Global Policy. DOI: 10.1111/1758-5899.12827.

"To date there has been little focus on the optimum strategies for integrating land‐based CDR approaches – under which circumstances forest areas are best left undisturbed, managed for conservation, and/or managed for harvested wood products, and how these options affect the availability of residual feedstocks for BECCS. This paper reviews this debate and suggests appropriate policy measures."

Rickels, Wilfried; et al. (2020): The Future of (Negative) Emissions Trading in the European Union

Rickels, Wilfried; Proelss, Alexander; Geden, Oliver; Burhenne, Julian; Fridahl, Mathias (2020): The Future of (Negative) Emissions Trading in the European Union. In Kiel Working Paper (2164).

"This conceptual paper explores various design options for integrating negative emissions technologies (NETs) into the EU ETS. We discuss their potential implications for emissions trading at large and address the specificity of bioenergy with carbon capture and storage (BECCS); repealing the provision that installations exclusively using biomass are not covered by the ETS Directive, BE(CCS) installations could in principle fall within the scope of the ETS Directive."

Digdaya, Ibadillah A.; et al. (2020): A direct coupled electrochemical system for capture and conversion of CO2 from oceanwater

Digdaya, Ibadillah A.; Sullivan, Ian; Lin, Meng; Han, Lihao; Cheng, Wen-Hui; Atwater, Harry A.; Xiang, Chengxiang (2020): A direct coupled electrochemical system for capture and conversion of CO2 from oceanwater. In Nat Comms 11 (1), p. 4412. DOI: 10.1038/s41467-020-18232-y.

"Capture and conversion of CO2 from oceanwater can lead to net-negative emissions and can provide carbon source for synthetic fuels and chemical feedstocks at the gigaton per year scale. Here, we report a direct coupled, proof-of-concept electrochemical system that uses a bipolar membrane electrodialysis (BPMED) cell and a vapor-fed CO2 reduction (CO2R) cell to capture and convert CO2 from oceanwater."

Puno, Railla Veronica D. (2020): A Rights-Based Approach to Governance of Climate Geoengineering

Puno, Railla Veronica D. (2020): A Rights-Based Approach to Governance of Climate Geoengineering. In ELR 10744.

"This Article explores a rights-based approach for the governance of geoengineering in international law, including the impetus, rationale, and options for implementation. The approach would take into account the need for participation, accountability, nondiscrimination, and equality in its development and deployment, while addressing the potential of such technologies in mitigating the impacts that climate change would have to the full enjoyment of human rights, including the right to a healthy environment."

Visioni, Daniele; et al. (2020): Reduced Poleward Transport Due to Stratospheric Heating Under Stratospheric Aerosols Geoengineering

Visioni, Daniele; MacMartin, Douglas G.; Kravitz, Ben; Lee, Walker; Simpson, Isla R.; Richter, Jadwiga H. (2020): Reduced Poleward Transport Due to Stratospheric Heating Under Stratospheric Aerosols Geoengineering. In Geophysical Research Letters 47 (17). DOI: 10.1029/2020GL089470.

"We show how the heating results in a feedback where increasing injection rates lead to stronger high‐latitudinal transport barriers. This implies a potential limitation in the high‐latitude aerosol burden and subsequent cooling."

Kravitz, Ben; et al. (2020): Comparing different generations of idealized solar geoengineering simulations in the Geoengineering Model Intercomparison Project (GeoMIP)

Kravitz, Ben; MacMartin, Douglas G.; Visioni, Daniele; Boucher, Olivier; Cole, Jason N. S.; Haywood, Jim et al. (2020): Comparing different generations of idealized solar geoengineering simulations in the Geoengineering Model Intercomparison Project (GeoMIP). In Atmospheric Chemistry and Physics (under review). DOI: 10.5194/acp-2020-732.

"Two generations of models in the Geoengineering Model Intercomparison Project (GeoMIP) have now simulated offsetting a quadrupling of the CO2 concentration with solar reduction. This simulation is artificial and designed to elicit large responses in the models. Here we show that energetics, temperature, and hydrological cycle changes in this experiment are statistically indistinguishable between the two ensembles."

"Forecasts by economists of the economic damage from climate change have been notably sanguine, compared to warnings by scientists about damage to the biosphere."

Dooley, Kate; et al. (2020): Carbon‐dioxide Removal and Biodiversity: A Threat Identification Framework

Dooley, Kate; Harrould‐Kolieb, Ellycia; Talberg, Anita (2020): Carbon‐dioxide Removal and Biodiversity: A Threat Identification Framework. In Global Policy. DOI: 10.1111/1758-5899.12828.

"We present a framework for assessing the impacts (positive or negative) on biodiversity and ecosystems from a spectrum of CDR interventions, so as to prioritize research to those CDR options that present minimal threats to biodiversity. Application of the framework indicates that while many CDR interventions present threats to biodiversity, certain options, such as regenerative CDR, may have positive impacts."
