碩士 / 國立成功大學 / 環境工程學系碩博士班 / 94 / This study aims to identify the trends and changes of energy consumption and CO2 emission of road transportation sector in Taiwan from 1999 to 2004.The Divisia index decomposition analysis was applied to identify main factors which affect CO2 emission changes in road transportation sector. In addition, OECD and Tapio decoupling methods were utilized to analysis the variations and relationships of the road transportation sector among economic development, energy-consuming, CO2 emission, vehicles counting and oil price.
Results of decomposition analysis in whole road transportation sector indicated that economic growth was the main factor for the increase of CO2 emission, vehicles for every thousand people was the second increasing factor, while the human intensity was the main factor for the decrease of CO2 emission, the vehicle energy consumption intensity and CO2 emission coefficient were the 2nd and 3rd decrement factors respectively. Results for gasoline cars and diesel cars have shown similar results as the whole road transportation sector. While diesel vehicle energy consumption intensity was the factor for the increase of CO2 emission.
OECD decoupling analysis for the whole road transportation sector demonstrated that the decoupling factors of CO2 emission coefficient、energy intensity、CO2 pollution intensity and vehicle energy consumption intensity appeared to be rising, which indicated that the decoupling phenomena has been improved. The decoupling factor of vehicles for every thousand people has shown a decreasing trend indicated that the environmental pressure has been worsen. Results in the gasoline cars showed that the decoupling phenomena of gasoline cars energy consumption intensity have been improved. The decoupling factor of gasoline vehicles for every thousand people has a declined trend which indicated that the environmental pressure was worsen. The results in diesel car has shown that the decoupling factors of diesel vehicle energy consumption intensity and diesel vehicles for every thousand people appeared to be decreasing, which indicated that environmental pressure from the diesel vehicles have been worsen.
Tapio decoupling analysis for the whole road transportation sector demonstrated that the CO2 emission coefficient、energy intensity、CO2 pollution intensity and the vehicle energy consumption intensity were in expansive coupling states, which indicated that they have improved phenomena. The vehicles for every thousand people was the expansive negative decoupling state, which indicated that CO2 emission increases. The results in gasoline cars showed that the gasoline vehicle energy consumption intensity and gasoline vehicles for every thousand people have shown similar results as the whole road transportation sector. On the other hand, diesel vehicles showed that the diesel vehicle energy consumption intensity and diesel vehicles for every thousand people were both in expansive negative decoupling states, which indicated that environmental pressure from the diesel vehicles has become worsen.
