Abstract

One of the major interests of governments in the area of environmental protection is to reduce greenhouse gas (GHG) emissions and air pollutants’ emissions (HC, CO, NOx, PM, and SOx) from vehicles. This paper aims at evaluating the efficiency of green and diesel vehicles. Two hundred fifty vehicles were selected for comparison study. The results show that the efficiency of each type of vehicle hardly differed in 2008 and 2009, but the gap between green and diesel vehicles became significant in 2010–2012. The results also indicate that larger automotive companies and smaller green vehicles show higher efficiency in recent years, whereas the type of green vehicles and the origin of automotive companies are not significantly related to the efficiency score of green vehicles. These findings provide more information for understanding differences in green vehicles.
