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."

Phys.org: Researchers explore the use of decision pathways to inform climate engineering policies

Media response to Gregory, Robin; et al. (2016). "A collaborative of researchers from the U.S. and Canada propose a decision pathway approach that offers some of the benefits of traditional survey techniques, while also capturing the reasoning of deliberations within groups, and helping participants to deepen their knowledge of issues and solutions. The researchers have modeled this approach with a decision pathway design that addresses climate engineering technologies, and published their results in the Proceedings of the National Academy of Sciences."

Buckholtz, Michelle Carolina (2015): Decision analysis for climate engineering research

Buckholtz, Michelle Carolina (2015): Decision analysis for climate engineering research. University of Texas at Austin.

Masters thesis. "This report identifies the unique characteristics which make climate engineering an important tool in the portfolio of strategies for managing climate change risks. Next potential benefits and costs associated with the technology are explored. The largest ethical objections to research and use of the technology are discussed and presented in a more consistent framework than found in existing literature."

Manoussi, Vassiliki; Xepapadeas, Anastasios (2015): Cooperation and Competition in Climate Change Policies. Mitigation and Climate Engineering when Countries are Asymmetric

Manoussi, Vassiliki; Xepapadeas, Anastasios (2015): Cooperation and Competition in Climate Change Policies. Mitigation and Climate Engineering when Countries are Asymmetric. In Environ Resource Econ. DOI: 10.1007/s10640-015-9956-3

"We study a dynamic game of climate policy design in terms of emissions and solar radiation management (SRM) involving two heterogeneous countries or group of countries. Countries emit greenhouse gasses (GHGs), and can block incoming radiation by unilateral SRM activities, thus reducing global temperature. Heterogeneity is modelled in terms of the social cost of SRM, the environmental damages due to global warming, the productivity of emissions in terms of generating private benefits, the rate of impatience, and the private cost of geoengineering."

Manning, David A. C.; Renforth, Phil (2013): Passive Sequestration of Atmospheric CO 2 through Coupled Plant-Mineral Reactions in Urban soils

Manning, David A. C.; Renforth, Phil (2013): Passive Sequestration of Atmospheric CO 2 through Coupled Plant-Mineral Reactions in Urban soils. In: Environ. Sci. Technol. 47 (1), pp. 135–141.

"It offers a sustainable carbon dioxide removal mechanism analogous to the use of constructed wetlands for the passive remediation of contaminated waters, and is likely to achieve wide public acceptance."
