Exploring Decarbonization Pathways for USA Passenger and Freight Mobility
10/30/2023
Passenger and freight travel account for 28% of U.S. greenhouse gas (GHG) emissions today. This report explores pathways to reduce transportation emissions under bounding assumptions on future travel behavior, technology advancement, and policies. Results show diverse routes to 80% or more well-to-wheel GHG reductions by 2050. Rapid adoption of zero-emission vehicles coupled with a clean electric grid is essential for deep decarbonization. Increased sustainable biofuel usage is also essential for decarbonizing aviation and to support legacy vehicles during the transition. Managing travel demand growth can ease this transition by reducing the need for clean electricity and sustainable fuels.
