McQueen, Noah; et al. 2020: “Cost Analysis of Direct Air Capture and Sequestration Coupled to Low-Carbon Thermal Energy in the United States."

McQueen, Noah, Peter Psarras, Hélène Pilorgé, Simona Liguori, Jiajun He, Mengyao Yuan, Caleb M. Woodall, Kourosh Kian, Lara Pierpoint, Jacob Jurewicz, J. Matthew Lucas, Rory Jacobson, Noah Deich, and Jennifer Wilcox. 2020: “Cost Analysis of Direct Air Capture and Sequestration Coupled to Low-Carbon Thermal Energy in the United States." Environmental Science & Technology. https://pubs.acs.org/doi/10.1021/acs.est.0c00476?ref=pdf.

‌"This study outlines a roadmap for DAC cost reductions through the exploitation of low-temperature heat, recent U.S. policy drivers, and logical, regional end-use opportunities in the United States. Specifically, two scenarios are identified that allow for the production of compressed high-purity CO2 for costs ≤$300/tCO2, net delivered with an opportunity to scale to 19 MtCO2/yr."

Bloomberg Green: Why Oil Giants Figured Out Carbon Costs First: Gernot Wagner

"In 1991, an Exxon subsidiary calculated the need for a price of $75 per ton of carbon dioxide to stabilize Canada's carbon emissions—a steep price much higher than even today’s consensus views."

Call for Abstracts: Ocean-based negative emission technologies: Feasibility, costs and side-effects (EGU)

Deadline: 10. January 2019

"In this session we want to bring together experts on ONETs to assess and discuss their feasibilities, costs, and side-effects. We explicitly also welcome experts working on interactions between, as well as mutual benefits of, ocean- and land-based NETs."

news.com.au: Extreme measures the world may have to consider if it doesn’t act on climate change

"THE world seems incapable of taking decisive action on climate change but we may soon have to consider some bizarre options to stop global warming if we fail to act. The Paris Agreement sets a target of well under 2 degrees celsius warming and researchers decided to look at how much it would cost to achieve this target, and the more ambitious target of 1.5C, as well as what the potential benefits were."

Science News: Big increase in economic costs if cuts in greenhouse gas emissions are delayed

"A comprehensive new analysis involving researchers from UEA warns that the target of limiting global warming to 1.5ºC could soon become too economically expensive to justify, despite the benefits it could provide."

NextBigFuture: Point of no return for climate action is point when Geoengineering will start

"So-called solar geoengineering aims to cool the planet by deflecting some of the Sun’s incoming rays. Ideas for accomplishing this include the dispersion of light-scattering particles in the upper atmosphere, which would mimic the cooling effect of major volcanic eruptions."

Roshan, Elnaz; et al. (2018): Cost-Risk Trade-Off of Mitigation and Solar Geoengineering. Considering Regional Disparities Under Probabilistic Climate Sensitivity

Roshan, Elnaz; M. Khabbazan, Mohammad; Held, Hermann (2018): Cost-Risk Trade-Off of Mitigation and Solar Geoengineering. Considering Regional Disparities Under Probabilistic Climate Sensitivity. In Environ Resource Econ 113 (9), p. 5886. DOI: 10.1007/s10640-018-0261-9.

"Here, we investigate to what extent a proponent of the 2 °C-temperature target would apply SGE in conjunction with mitigation in view of regional disparities in temperature and precipitation. We apply cost-risk analysis (CRA), which is a decision analytic framework that trades-off expected welfare-loss from climate policy costs and climate risks from transgressing a climate target. Here, in ‘Giorgi’-regional-scale analyses, we evaluate the optimal mix of SGE and mitigation under probabilistic information about climate sensitivity and generalize CRA in order to include regional temperature and precipitation risks."

Benson, Sally M. (2014): Negative-emissions insurance

Benson, Sally M. (2014): Negative-emissions insurance. In Science 344 (6191), p. 1431. DOI: 10.1126/science.1257423.

"Among the most promising CDR methods are reforestation, afforestation (planting new forests), and bioenergy with carbon capture and storage (BECCS). However, for BECCS strategies to succeed, major hurdles must be overcome."

Power: Geoengineering: A Practical Climate Climate Work-Around or Just Plain Crazy?
