The climate change is viewed as the important issue in the world, and many researchers discussed effective ways of the reduction of green-house gas and the impacts of climate change. In Korea we need to reduce transportation energy consumption accounting for about 16.5 percent of domestic greenhouse gas emissions. The purpose of this study is to analyze CO2 emissions according to transportation energy consumption. The spatial unit in this study is the city-region which is designated by the travel pattern of passenger cars, since travel patterns are becoming wide beyond the administrative district. Korea was set to 23 city-regions as integrating commuting trips. Average VKT (Vehicle Kilometer Travelled) is much higher in small and medium city-regions than large city-regions. VKT per person is also much longer in cities and counties located nearby metropolitan areas. This study constructed city-regional profile and classified 5 types of characters by the transportation energy consumption factors. The result of this research gives some implications for establishing and promoting policies according to the different characteristics of large and small city-regions to reduce the transportation energy consumption and effective CO2 emission reduction.
