Exploring decarbonization pathways for USA passenger and freight mobility

C. Hoehne, M. Muratori, et al.

This research by Christopher Hoehne and colleagues investigates how passenger and freight travel significantly impact U.S. greenhouse gas emissions and explores strategies to achieve major reductions by 2050. The study highlights the importance of adopting zero-emission vehicles, enhancing electric grid sustainability, and utilizing more biofuels to meet these challenges effectively.

Abstract

Passenger and freight travel contribute significantly to U.S. greenhouse gas (GHG) emissions. This paper explores pathways to reduce these emissions using NREL’s TEMPO model, considering various assumptions about travel behavior, technology, and policies. Results indicate diverse routes to substantial GHG reductions by 2050, emphasizing the need for rapid zero-emission vehicle adoption, a clean electric grid, and increased sustainable biofuel use. Managing travel demand growth can also ease the transition.
