本研究主要目的為針對台灣地區公路運輸部門,探討公路運輸部門自民國79年至93年間能源消費及CO2排放量的變動趨勢,利用因素分解迪氏指標法探討影響其排放變動之關鍵因素,並利用OECD與Tapio兩種脫鉤指標法,觀察公路運輸部門在經濟發展、能源消費、CO2 排放、車輛數、油價之間的發展與變化關係,以作為未來運輸部門研擬邁向永續發展與CO2減量策略之參考。
因素分解結果顯示,在整體公路運輸部門方面,經濟成長為主要增量因素,其次為每千人擁有車輛數;而人力密集度為主要減量因素,其次分別為車輛能耗度與CO2排放係數。在汽油車方面,經濟成長為主要增量因素,其次為每千人擁有車輛數;而人力密集度為主要減量因素,其次為車輛能耗度。在柴油車方面,經濟成長為主要增量因素,其次分別為每千人擁有車輛數與車輛能耗度;而人力密集度為唯一減量因素。
OECD脫鉤指標分析結果顯示,在整體公路運輸部門方面,CO2排放係數、能源密集度、CO2污染密集度及車輛能耗度,脫鉤因子整體呈現上升的趨勢,顯示有改善的現象;每千人擁有車輛數整體脫鉤因子為逐年下降的趨勢,顯示環境壓力惡化。在汽油脫鉤結果方面,汽油車能耗度各年度皆為無脫鉤狀態,脫鉤因子整體呈現上升的趨勢,顯示車輛能耗度有所改善;每千人擁有汽油車輛數各年度皆為無脫鉤狀態,脫鉤因子呈現持續下降趨勢,顯示環境壓力惡化。在柴油脫鉤結果方面,柴油車能耗度脫鉤因子整體為下降趨勢,顯示柴油車能耗度惡化;每千人擁有柴油車輛數各年度皆為無脫鉤狀態,脫鉤因子呈現持續下降趨勢,顯示環境壓力惡化。
Tapio脫鉤指標分析結果顯示,在整體公路運輸部門方面,CO2 與能源消費量、能源消費量與全國GDP、CO2 排放量與全國GDP及能源消費量與全國車輛數皆為擴張連結狀態,顯示CO2排放係數、能源密集度、CO2密集度及車輛能耗度有改善的現象;全國車輛數與全國人口呈現擴張負脫鉤狀態,顯示CO2排放量增加。在汽油車方面,汽油消費輛與汽油車輛數為擴張連結狀態,顯示車輛能耗度有所改善;汽油車輛數與全國人口數呈現擴張負脫鉤狀態,顯示車輛數成長大於人口數成長。在柴油車方面,柴油能源消費與柴油車輛為擴張負脫鉤狀態,顯示柴油車能耗度惡化;柴油車輛數與全國人口數呈現擴張負脫鉤狀態,顯示每千人擁有車輛數增加。
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.
