CSIS is an American think tank that explores “practical ideas to address the world’s greatest challenges,” one of which is climate change. One difficulty is identifying public policy interventions that will both (1) effectively reduce greenhouse gas emissions and (2) be practical to implement in today’s international economic and political environment. The CSIS Clinic team has developed a model simulating the complex and dynamic interactions of international climate policy. This model will be used in tabletop simulations, helping CSIS staff understand political strategies for advancing global climate action.
