Fabre, Adrien; Wagner, Gernot (2019): Risky Geoengineering Option Can Make An Ambitious Climate Mitigation Agreement More Likely

Fabre, Adrien; Wagner, Gernot (2019): Risky Geoengineering Option Can Make An Ambitious Climate Mitigation Agreement More Likely, NYU Wagner Research Paper Forthcoming, 12/9/2019.

"Some countries prefer high to low mitigation (H > L). Some prefer low to high (L > H). That fundamental disagreement is at the heart of the seeming intractability of negotiating a climate mitigation agreement. Enter geoengineering (G). Its risky and imperfect nature makes it arguably inferior to any country’s preferred mitigation outcome. However, absent a global high-mitigation agreement, countries facing disastrous climate damages might indeed wish to undertake it, effectively ranking H > G > L."

Khaleej Times: Climate kids have our attention, but change has to come through govts

"We owe today's young activists a huge debt for sounding the alarm. Now, we need to turn their enthusiasm into an institutionalised political force, and develop a blueprint for a productive economic agenda."

Greenbiz: Exploring the business case for carbon removal

"While it clearly will take substantial investments to put many of these natural and technological approaches into practice, the numbers associated with the markets they could open certainly are eye-catching."

Daniel, K.; et al. (2019): Declining CO2 price paths

Daniel, Kent D.; Litterman, Robert B.; Wagner, Gernot (2019): Declining CO2 price paths. In: PNAS, S. 201817444. DOI: 10.1073/pnas.1817444116.

"Risk and uncertainty are important in pricing climate damages. Despite a burgeoning literature, attempts to marry insights from asset pricing with climate economics have largely failed to supplement—let alone supplant—decades-old climate–economy models, largely due to their analytic and computational complexity. Here, we introduce a simple, modular framework that identifies core trade-offs, highlights the sensitivity of results to key inputs, and helps pinpoint areas for further work."

National Academy of Sciences, Engineering, and Medicine (2019): Gaseous Carbon Waste Streams Utilization

National Academy of Sciences, Engineering, and Medicine (2019): Gaseous Carbon Waste Streams Utilization. Washington, D.C.: National Academies Press.

"In the quest to mitigate the buildup of greenhouse gases in Earth’s atmosphere, researchers and policymakers have increasingly turned their attention to techniques for capturing greenhouse gases such as carbon dioxide and methane, either from the locations where they are emitted or directly from the atmosphere. Once captured, these gases can be stored or put to use. While both carbon storage and carbon utilization have costs, utilization offers the opportunity to recover some of the cost and even generate economic value."

Moreno-Cruz, Juan B.; et al. (2018): An Economic Anatomy of Optimal Climate Policy

Moreno-Cruz, Juan B.; Wagner, Gernot; Keith, David W. (2018): An Economic Anatomy of Optimal Climate Policy. Munich Society for the Promotion of Economic Research ‐ CESifo (CESifo Working Papers).

"This paper introduces geoengineering into an optimal control model of climate change economics. Together with mitigation and adaptation, carbon and solar geoengineering span the universe of possible climate policies. Their wildly different characteristics have important implications for climate policy."

Ott, Konrad (2018): On the Political Economy of Solar Radiation Management

Ott, Konrad (2018): On the Political Economy of Solar Radiation Management. In Front. Environ. Sci. 6, p. 29. DOI: 10.3389/fenvs.2018.00043.

"The paper concludes that the U.S. economic system has strong affinities to SRM supported by an emerging agency network that tries to establish a pro-SRM narrative and launch SAI research initiatives. There is recent evidence that SRM has found support from policy makers. To supporters of “green” variants of capitalism, the main claims of the article provide reasons against SAI-research. The article finishes with some remarks why SAI-research should be conditional."
