自1970年以來，過去五十年間，台灣高速公路網路從最初的373公里擴展到超過1000公里，以應對日益增長的交通需求並支持國家經濟發展。這個高品質的高速公路系統已成為台灣交通基礎設施的骨幹，目前承擔約65%的城際交通量。 未來之展望，在高速公路局持續的努力下，秉持著服務品質提升、推動智慧交通管理、全面實施全生命周期維護及推動節能減碳策略，這些理念旨在支持國家的整體經濟成長。在高速公路維護方面，目前設有三個區域分局，包含14個工務段。年度維護預算超過2.16億美元，涵蓋橋梁、隧道、邊坡、路面以及機電系統等多種基礎設施組件。自從台灣制定2050淨零碳排政策以來，各行業積極發展新產品、施工方法和材料，以走向節能減碳之路。考量到各工務段的年度合約金額均超過1500萬美元，這些工務段勢必需要進行碳盤查工作。透過引入ISO 14064-1:2018組織碳盤查標準，可系統性地量化和追蹤維護過程中的溫室氣體排放，有助於工務段制定長期的節能與減碳政策並量化其成效。碳盤查過程涵蓋營運中的直接排放源、隧道機電設備及道路維護工程的間接排放，以及轄區內樹木的碳吸存資料。碳盤查結果不僅有助於明確碳減量優先項目，亦可量化節能減碳成效。本研究將分析此方法如何促進工程管理與永續發展目標的平衡，並提供實務建議，協助相關單位推動淨零碳排目標的達成。;Since 1970， over the past five decades， Taiwan’s freeway network has expanded from an initial 373 kilometers to over 1，000 kilometers to meet increasing transportation demands and support national economic development. This high-quality freeway system has become the backbone of Taiwan′s transportation infrastructure， currently handling approximately 65% of intercity traffic. Looking ahead， under the continuous efforts of the Freeway Bureau， the focus remains on enhancing service quality， implementing intelligent transportation management， promoting full life-cycle maintenance， and advancing energy-saving and carbon reduction strategies. These principles aim to support the nation’s overall economic growth. In terms of freeway maintenance， there are currently three regional branches comprising 14 maintenance offices. The annual maintenance budget exceeds USD 216 million， covering a wide range of infrastructure components including bridges， tunnels， slopes， pavements， electromechanical systems. Since， Taiwan established the 2050 net-zero carbon emission policy， various industries have been actively developing new products， construction methods， and materials to follow the path of energy-saving and carbon reduction. Considering that the annual total contract value of each engineering section of the Taiwan National Highway Bureau exceeds 15 million USD， it is essential for these sections to independently conduct carbon inventory work. By introducing the ISO 14064-2018 organizational carbon inventory standard， they can systematically quantify and track greenhouse gas emissions during maintenance processes. This will also help the engineering sections formulate long-term energy-saving and carbon reduction policies and quantify their efforts. Carbon inventory process includes direct emission sources from operations， indirect emissions from tunnel electromechanical equipment and road maintenance engineering， as well as the collection of carbon sequestration data from trees within the jurisdiction. The results of the carbon inventory not only help identify carbon reduction priorities but also quantify the effectiveness of energy-saving and carbon reduction efforts. This paper will analyze how this approach facilitates balancing engineering management and sustainable development goals， providing practical recommendations for relevant units， contributing to the achievement of net-zero carbon emission targets.
