Making Climate Policy Models More Decision-relevant

Abstract: Efforts to achieve decarbonization targets often fall short. Integrated assessment models (IAMs) have been used widely to assess current policies and quantify the additional efforts needed to close the gap. Yet, IAMs still lack adequate considerations of socio-political factors that are central to climate policy making. This makes them overly abstract and simplistic to inform concrete decisions by national and subnational policymakers. In this talk, I will discuss our research focused on three areas to make IAMs more decision-relevant: 1) enhancing policy realism by incorporating political economy insights on policy heterogeneity and instrument choice; 2) assessing winners and losers of climate policy by coupling IAMs with fine-scale impact assessment models; and 3) identifying equitable policy strategies by assessing multiple objectives under future uncertainties. I will demonstrate a range of modeling examples, from the cost of state-driven climate policy in the U.S. to the unintended health effects from a global carbon price.
