EPA Trends on EVs and PHEVs; beginning of a “measurable and meaningful impact” on new vehicle fuel economy and emissions

Green Car Congress

The agency’s reasoning was that since alternative fuel vehicle production has generally been less than 0.1% of total vehicle production until very recently, the impact of excluding alternative fuel vehicles was negligible. Fuel economy average for the US fleet, per the Trends report, is 24.1

MIT study finds fuel economy standards are 6-14 times less cost effective than fuel tax for reducing gasoline use

Green Car Congress

In a study published in the journal Energy Economics , MIT researchers have found that a fuel economy standard is at least six to fourteen times less cost effective than a fuel tax when targeting an identical reduction in cumulative gasoline use (20% by 2050). —Karplus et al.

EPA trends report sees record levels of average new vehicle fuel economy and CO2 emissions for MY 2012; role of new gasoline vehicle technologies

Green Car Congress

EPA projects advanced transmissions (6+ speeds and CVTs), gasoline direct injection (GDI) systems, and turbocharged engines will be installed on at least 15% of all MY 2013 vehicles. The majority of the emissions and fuel savings from current vehicles, EPA noted, is due to new gasoline vehicle technologies. Click to enlarge.

EIA projects decline in transportation sector energy consumption through 2037 despite increase in VMT, followed by increase

Green Car Congress

For the Transportation sector, EIA projects that energy consumption will decline between 2019 and 2037 (in the Reference case) because increases in fuel economy more than offset growth in vehicle miles traveled (VMT). This growth arises from increases in air transportation outpacing increases in aircraft fuel efficiency.
