Long-Term Environmental Problems And Strategic Intergenerational Transfers, Timo Goeschl, Daniel Heyen, Juan B. Moreno-Cruz

The impacts of long-lived stock pollutants and the measures supposed to address them link current and future generations. Altruism towards successor generations is a prerequisite for resolving the resulting inter-generational equity issues. Preference asymmetry and imperfect altruism introduce strategic conflicts between generations. Here, a current generation decides on a combination of abatement and whether to provide an imperfect backstop. The future generation decides whether to use the backstop or not. We identify three outcomes: (1) Technology denial, in which the current generation deliberately rejects the imperfect backstop to avoid misuse by the future generation. (2) Under-abatement, in which the current …

We develop a simple measure of the potential effectiveness of solar radiation management (SRM) in compensating for anthropogenic climate change and test this measure using data from an ensemble of modeling experiments conducted with a general circulation model (GCM). Assuming a linear relationship between the amounts of SRM implemented globally and the regional temperature and precipitation responses to that change, we calculate the amount of SRM that minimizes impacts using three different social objectives: egalitarian, utilitarian and ecocentric. While inequalities in the effectiveness of SRM between regions are important, they may not be as severe as is often assumed. When …

Climate Policy Under Uncertainty: A Case For Solar Geoengineering, Juan B. Moreno-Cruz, David W. Keith

It appears to be technically feasible to engineer an increase in albedo, a planetary brightening, as a means to offset the warming caused by carbon dioxide (CO2) and other greenhouse gases through Solar Radiation Management (SRM). This option has two characteristics that make it attractive for managing climate risk: it is quick and cheap. However, SRM cannot exactly compensate for the CO2-driven climate change. Moreover, SRM introduces risks in the climate system that are unique to this type of intervention.We introduce SRM in a model of climate change economics and analyze the optimal policy under uncertainty. We find that the …
