Analyzes impacts of emerging vehicle efficiency technologies on consumer fuel savings, benefit-to-cost ratio, and payback period in the 2025–2030 time frame.
Summarizes the status of electric vehicle market in California through 2016, quantifying electric vehicle market growth across California cities and metropolitan areas.
Evaluates the trajectory of GHG emissions from international aviation in the U.S. and Canada as well as the possible GHG reductions that could be made from deployment of alternative jet fuels (AJFs) within the framework of the International Civil Aviation Organization’s (ICAO) Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA).
Reviews the political science, regulatory, and economics literature to illuminate the international competitiveness impacts of motor vehicle emission standards.
Evaluates the effect of Euro VI-equivalent emissions standards on bus system costs in Brazil.
Highlights important innovations and trends in vehicle design technology and lightweighting, many of which were not considered when the 2025 CAFE standards were finalized, but promise to be quite cost-effective.
Reviews the structure of EPA’s emission recall program for light-duty vehicles and trucks (LDV and LDT) and its effectiveness over time and also explains the recall authority, procedures, and coordination among offices.
Identifies key differences in the regulations governing certification of NOx emissions from diesel cars (Euro 6) and trucks (Euro VI) that help explain differences in their real-world emissions performance. Ultimately, an examination of the HDV regulation reveals insights that could be used to improve the LDV regulation.
This technical brief highlights important innovations and trends in downsized and turbocharged gasoline engines, several of which were not considered when the 2025 CAFE standards were finalized, but promise to be quite cost-effective.
A concise overview of the EU's vehicle CO2 emission reduction requirements, targets for 2025–2030 that are coming under consideration, and current best projections of vehicle-specific CO2 reduction technology potential and costs in that time frame.
