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.

MIT study finds significant economic and environmental benefits from designing US LDVs to use higher octane gasoline (98 RON)

Green Car Congress

In a companion study to an SAE paper presented in April ( earlier post ), researchers at MIT have quantified the net economic and CO 2 emissions benefit that could be obtained by utilizing 98 RON gasoline in light-duty vehicles, based on reasonable assumptions for possible refinery changes and the evolution of the LDV fleet.

Researchers find consumers compensate for fuel-efficient car by buying bigger second vehicle; losing 60% of fuel economy savings

Green Car Congress

An analysis by a team from the University of California, Davis, MIT and Yale suggests that households that buy a fuel-efficient vehicle tend to compensate for that purchase by buying a bigger, more powerful second vehicle. This unintended effect could erode goals of fuel economy standard policies by up to 60%.
