A European study indicates that the widespread adoption of new vehicle technologies and fuels, along with mode shifts, can help stabilize atmospheric concentrations of greenhouse gases (GHGs) within targeted ranges—but strong policy actions and a willingness to embrace change are needed. The study indicates that by 2050 cutting transport energy use and carbon dioxide emissions by nearly half should be technically possible through improvements in vehicle energy efficiency, and by nearly half again by substituting low carbon dioxide alternative fuels—mainly electricity, hydrogen, and biofuels. Shifting traffic to GHG-efficient modes should be helpful before the vehicle technologies and fuels are heavily deployed.
