Abstract

Reducing the United States’ greenhouse gas emissions by at least 80% from 1990 levels by 2050 will require multiple legal pathways for changing its transportation fuel sources. The Deep Decarbonization Pathways Project (DDPP) authors characterize transforming the transportation system as part of a third pillar of fundamental changes required in the U.S. energy system: “fuel switching of end uses to electricity and other low-carbon supplies.” The goal is to shift 80%-95% of the miles driven from gasoline to energy sources like electricity and hydrogen. Relying upon the DDPP analysis, this Article, excerpted from Michael B. Gerrard & John C. Dernbach, eds., Legal Pathways to Deep Decarbonization in the United States (forthcoming in 2018 from ELI Press), addresses that challenge as applied to light-duty vehicles such as cars and SUVs.
