ABSTRACT:

More than 100 countries have proposed or are considering a net zero emissions target for mid-century. But how can we get there? To assess future decarbonization pathways, integrated assessment modeling methods (IAMs) have been used to model the coupled human-natural system and evaluate the cost and environmental implications of different mitigation strategies. While most IAMs still focus on optimal, idealized policies, real-world decisions need to balance competing objectives, manage future uncertainties, and ensure political feasibility. In this talk, I will discuss recent efforts from my group to advance IAMs by: a) adding decision science methods to identify robust strategies under future uncertainties, and b) adding social science insights to identify realistic strategies under social and political constraints. I will demonstrate a range of modeling examples, from the surprisingly inexpensive cost of state-driven climate policy in the United States to the unequal regional distribution of air pollution and health effects from a global carbon price.
