Abstract:

For the past several years, we have calculated (on a monthly basis) the average, sales-weighted fuel economy of all light-duty vehicles (cars, pickup trucks, vans, and SUVs) sold in ; the U.S. The results indicate that, from October 2007 to September 2014, the average fuel ; economy has improved from 20.1 mpg to 25.3 mpg. This brief note quantifies the ; consequences of this improvement on overall fuel consumption and vehicle emissions. ; Because of their improved fuel economy, the vehicles sold since October 2007 saved a ; cumulative total of about 15.1 billion gallons of fuel—equivalent to the current total ; consumption of all vehicles in the U.S. for about 33 days. This reduction in the amount of fuel ; translates to a reduction of about 297 billion pounds of carbon-dioxide emissions. ; In terms of the current savings, for the most recent month—September 2014—the savings ; amount to 614 million gallons of fuel, or about 12 billion pounds of carbon dioxide. These ; savings are equivalent to about 6% of both the average monthly fuel consumption and carbon-dioxide emissions from all light-duty vehicles on the road.
