Abstract:
Heavy-duty trucks dominate U.S. freight energy use and greenhouse gas (GHG) emissions. They account for approximately one-fifth of the GHGs emitted from the transportation sector and for 80% of the GHGs associated with the movement of all freight. In this article, the author reviews strategies and technologies to reduce total freight emissions from large trucks and their operations, including payload efficiency, shifting modes, energy efficiency, and low-carbon fuels.
