EMF 22: Climate Change Control Scenarios

Main content start



John Weyant 


This study focuses on comprehensive analyses of long-run climate stabilization policies as well as intermediate-term transition scenarios (derived either by working backwards from stabilization targets or forward via policies that seem more rather than less likely to actually be adopted).

The goal of EMF 22 was to construct a high quality, coordinated set of policy scenarios using state of the art models to inform ongoing and upcoming climate policy discussions.  In particular, EMF 22 focused on moving away from idealized policy scenarios, which have been the primary focus of international modeling, toward scenarios that are more representative of real policy discussions today.  

EMF 22 was constructed with three distinct subgroups: an international subgroup, a U.S. subgroup, and an E.U. subgroup and each of them summarized the study design and provided an overview and key results across the models.  For the Special issue by Energy Economics, follow the link below.
