Electric cars have taken over this year’s Greenest Vehicles List published by the American Council for an Energy-Efficient Economy (ACEEE). The 19th annual environmental rankings published on greencars.org featured nine electric vehicles (EV). The following vehicles comprise the Greenest List for 2016:

For the third year in a row, the Smart ForTwo Electric Drive tops the Greenest List. Toyota’s Prius line continues to perform well, with the new Prius Eco nabbing the 4th spot, while the Prius C and original Prius claim spots #8 and #9. For the first time ever, the Greenest list is completely populated by plug-in and hybrid vehicles; not a single vehicle with only an internal combustion engine appears.

“The 2016 scores are in, and plug-in electric vehicles are outpacing all other vehicle offerings in terms of environmental friendliness. Fortunately, the electricity sector is slated to become cleaner over the life of model year 2016 vehicles, thanks to the Clean Power Plan, and that has bumped up electric vehicles’ green scores this year. Nevertheless, it’s important to acknowledge that how green your electric vehicle truly is depends on the electricity it uses to charge,” said ACEEE Lead Vehicle Analyst Shruti Vaidyanathan.

The newest additions to the list are the Volkswagen eGolf and the Kia’s Soul electric vehicle, which claim the #5 and #7 spots respectively. This year marks the first time a Kia vehicle has earned a top spot since 2009. The improved 2016 Chevrolet Volt also nabs a spot this year (#11) thanks to significant increases in fuel economy and its new streamlined vehicle design.

Modern clean diesels have repeatedly placed well in ACEEE’s annual ranking. However, following the EPA announcement that Volkswagen had cheated federal emissions standards since 2009, greenercars.org suspended its Green Scores for all affected VW, Audi, and Porsche diesel models.

Greenercars.org also identifies practical options in each class among the top widely available, automatic transmission, petroleum-fueled models, since many of the vehicles on the Greenest list are not widely available. The Greener Choices list include the Chevrolet Trax and the GMC Canyon.
