Automaker Rankings 2014

The numbers are in, the scores are tallied, and the winner is clear: Hyundai-Kia is the Greenest Automaker in our 2014 environmental rankings.

All eight of the best-selling automakers showed improvements in the rankings, which measure the pollution emissions of each automaker’s fleet. Thanks to strong federal and state emissions standards, the average new car has gotten 43 percent cleaner since 1998.

Despite this progress, the Detroit “Big Three”—Ford, General Motors, and Chrysler—still lag behind, with higher than average smog-forming and global warming pollution emissions. Continued investment in fuel-saving technologies will help these and other automakers offer consumers the cleanest, greenest vehicles possible.
