Energy-Conservation Group Posts Greenest Vehicle List

The American Council for an Energy-Efficient Economy (ACEEE) released its 15th “Greenest” vehicles’ list. It was dominated by new models, with the Toyota Prius C securing the top spot with a Green Score of 58. Having made its debut on the American vehicle market in 2012, the Prius C is Toyota’s compact addition to the Prius family. The original Prius, the new plug-in Prius hybrid and the larger Prius V, all made the “Greenest” list this year as well.

Other top scorers are the Honda Fit electric vehicle, coming in second, and the Honda Civic Hybrid, in fifth. Three Ford vehicles made the list: the Focus EV and the Fusion and C-Max hybrids. European vehicles also placed, with the Volkswagen new Jetta hybrid and the Smart ForTwo placing seventh and eighth.

This year, conventional vehicles were largely driven off the “Greenest” list by hybrid-electric, plug-in hybrid-electric and all-electric vehicles. The Scion IQ and Smart ForTwo are the only non-hybrid, non-plug-in vehicles to remain on the list. Even the eight-time first-place Honda Civic Natural Gas vehicle was pushed out of the top twelve in 2013. provides the facts necessary to examine the eco-performance of any 2013 model. Vehicles are analyzed on the basis of a Green Score, a singular measure that incorporates unhealthy tailpipe emissions, fuel consumption, and emissions of gases that contribute to climate change. This year, a number of updates were made to the methodology to more accurately estimate vehicles’ environmental impacts. These include updates to emissions from the vehicle manufacturing process, changes to gasoline, diesel and natural gas upstream emissions, and updates to the forecasted mix of fuels used to generate the electricity used to power electric cars.
