The average EPA fuel economy rating of new vehicles fell 0.1 mpg to 25.3 mpg in June, according to the University of Michigan's Transportation Research Institute (UMTRI).

The decline was attributed to increased sales of pickups, which drove sales of new vehicles during the month, according to according to UMTRI researchers Michael Sivak and Brandon Schoettle.

Fuel economy is down 0.5 mpg from the peak reached in August of 2014, but still up 5.2 mpg since October 2007 when UMTRI began its monitoring.

The University of Michigan Eco-Driving Index (EDI) — an index that estimates the average monthly emissions of greenhouse gases generated by an individual U.S. driver — reached 0.85 in April, an improvement of 0.01 from March. Tthe lower the value the better. This value indicates that the average new-vehicle driver produced 15% lower emissions in April than in October 2007, but 7% higher emissions than the record low reached in both August 2014 and August 2015.

The EDI takes into account both vehicle fuel economy and distance driven.
