Abstract

In this study, we analyze truck’s environmental costs per unit vehicle based on emissions of air pollutants and green house gases(GHGs) by its size and model year, and based on the costs we propose strategies for the expansion of the number of zero-emission trucks. In this study air pollutants and GHGs emissions are considered as air pollution by trucks. As methodology air pollutant emission coefficient equation by model type and model year distributed by the National Institute of Environmental Research, and GHGs emission equation (Tier 1) by emission activity specified in GHGs emission trading system are utilized to calculate the amount of emission reduction from tank to wheel. As results, its is analyzed that the truck of 12 tons or more are emit the largest amount of air pollutant and GHGs among different sizes of trucks. It is also analyzed that in general the larger the size and the older the model year it is, the more reduction it has when the diesel truck is replaced by zero-emission truck. and especially the increase of reduction amount is significant between Euro 4 and Euro 3 for large size trucks and Euro 5 and Euro 4 for small and medium size trucks. The environmental cost reductions per unit vehicle is analyzed as an average of KRW 1.3 million to KRW 20.3 million by vehicle type. Based on results, we proposed that a differentiated support strategy by truck size and model year is needed to effectively promote the zero-emission trucks replacing traditional diesel trucks.
