“All-In” Pathway to 2030: Transportation Sector Emissions Reduction Potential" demonstrates how an All-In pathway can deliver reductions in the transportation sector, representing nearly 20%—or one-fifth—of the emissions needed to achieve the U.S. NDC of 50-52% reductions by 2030 from 2005 levels. This pathway builds on reductions already underway—driven by years of consistent and robust action from non-federal actors—combined with actions on vehicle efficiency and new investment in charging stations and other areas authorized by Congress in IIJA. Additional measures from federal agencies and Congress can accelerate the deployment of electric vehicles (EVs), enhance electricity decarbonization, and extend reductions beyond 2030.
