In the aftermath of Dieselgate, diesel car sales shares are falling in Europe. But diesel's decline does not put EU CO2 targets out of reach. Other technologies offer more compelling and cost-effective pathways to reducing CO2 emissions from passenger cars.
Summarizes and analyzes preliminary data for 2016 recently released by the European Environment Agency (EEA) on CO2 emissions from new passenger cars in the EU. New cars sold in the EU in 2015 had average CO2 emissions of 118 g CO2/km, which was 1.2% lower than in 2015.
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).
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.
