我國陸上運輸節能分析與評估

環顧台灣各研究單位當中，對台灣交通運輸的整體耗能及節能統計的資料較為缺乏，故本研究首先蒐集來自交通部統計處及運研所的交通資料，進行應用研究，加入取自經濟部能源局及相關論文的能源消耗的因子，統計分析客運及貨運的總延人公里及延噸公里，進而估算現有交通運輸的能源消耗量。計算結果顯示在所有客運當中，以自用小客車的運輸量在台灣總交通運輸的占比最高，而且能源密集度亦是所有車種中最大者，故此部分的節能成效也最大。本研究最主要目的在於規劃與評估台灣陸上運輸節能政策，其中，牽涉到許多可推行的節能策略之運用，包括運具最佳可行技術的應用和公共運輸基礎建設的擴增，如果以2010年為基礎年，根據本研究針對2025年的我國陸上運輸節能情境分析，客運與貨運兩類共可節能2,931千公秉油當量，節能幅度高達27%，此一節能量占全國總耗能2.43%。相當於減少溫氣體排放為5.91百萬噸二氧化碳，此量占全國總排碳的2.40%，充分達到國家運輸部門的2025年減碳目標（5.2百萬公噸二氧化碳）。

Among the various research institutes in Taiwan, the overall transportation energy consumptions and energy saving statistics are quite in the lack. This study first of all collects the transportation data from Statistics Department and Institute of Transportation of the Ministry of Transportation and Communications to undergo the application research. Additionally, energy consumption factors are retrieved from the Bureau of Energy, Ministry of Economy and relevant papers; thereby, the energy consumptions of passenger and freight vehicles are analyzed statistically. Furthermore, the total energy consumption of current transportation is calculated. The calculation results show that the transportation capacity and energy intensity of passenger cars are the largest ones in the all land vehicles. Therefore, the passenger cars have the greatest potential for energy saving. Finally, this study sums up the implementation of energy-saving strategies, including the application of BAT (Best Available Technologies) and the augment of public transportation infrastructure. Through scenario analysis, the results of this study show that the national GHG abatement goal in 2025 (i.e., 5.2 Mt-CO2e) is fulfilled. Wherein, the energy-saving is 2,931 MKLOE with reduction rate of 27%, or 2.43% in national scale, while the GHG abatement is 5.91 Mt-CO2e or 2.40% in national scale.
