If you’re a tree-hugger, these cars aren’t for you. The American Council for an Energy-Efficient Economy (ACEEE) has put out its 2020 “meanest” list that details the worst cars for the environment, according to ACEEE’s criteria. It’s not just about gas mileage; the Council considers the entire environmental impact of a vehicle, including how it’s made, the materials used in it and how easy it is to be recycled.
Ten of the 12 are SUVs, all of which are either enormous, excessively quick — or both. Only one car and one full-size truck made the list. Check out all 12 of the offending — and, admittedly, awesome — vehicles below, starting with the worst.
Jeep Grand Cherokee Trackhawk (Green Score: 26/100)

The Trackhawk is a 707 horsepower monster. It earns just 11 mpg in the city and 17 mpg on the highway.
