What is a SmartWay Vehicle?

EPA's SmartWay program certifies the top 20% lowest-emitting cars and trucks for each model year. This provides car buyers with an easy way to identify the cleanest, most efficient vehicles. The very best of these vehicles earn the SmartWay Elite certification.

How does a vehicle get SmartWay certified?

EPA rates vehicles for GHG and smog-forming emissions on scales of 1 (worst) to 10 (best). To earn a SmartWay designation, a vehicle must receive a combined score (GHG rating + smog rating) that is significantly better than that of the average vehicle. SmartWay Elite is given to those vehicles that attain the highest scores on both scales. EPA updates the GHG and smog rating thresholds for each model year.
