摘要：	This National Research Council report assesses the potential for reducing petroleum consumption and greenhouse gas (GHG) emissions by the U.S. light-duty vehicle fleet by 80 percent by 2050. It examines the technologies that could contribute significantly to achieving these two goals and the barriers that might hinder their adoption. Four general pathways could contribute to attaining both goals, highly efficient internal combustion engine vehicles and vehicles operating on biofuels, electricity, or hydrogen. Natural gas vehicles could contribute to the additional goal of reducing petroleum consumption by 50 percent by 2030.
