Climate change impacts and mitigation costs affect people of highly different socioeconomic circumstances. How can one compare, for instance, the costs of reducing emissions to wealthy developed regions of the world with the benefits of climate change policy in very poor regions of the world, in which individuals might live in utter poverty? This project will examine different ethical approaches to that question, use numerical integrated assessment models to quantify optimal policies for different ethical frameworks, and try to find common policies that are robust with respect to different ethical approaches.
