因應近年來氣候異常所引發的種種環保議題，各國企業為能達到永續經營，紛紛將碳排放量（碳足跡）的因素納入產品整體生命週期循環過程中。然而產品的碳足跡計算必須動員生命週期中的各個合作廠商，且台灣企業多屬中小型的經營規模，面對不同業主的多變需求增加了合作廠商的作業負擔，本研究提出依服務導向架構來建構雲端碳足跡運算系統，以支援碳足跡盤查作業中各項繁瑣的資料彙整與表單作業。依據服務導向架構的服務確認步驟，找出各階段使用者所需的服務，並將其佈署於雲端運算環境，透過雲端運算環境的高可用性、高彈性與擴充性，供應鏈夥伴可使用不同的裝置來整合異質環境中的碳足跡資料，發展降低碳排放量的方案，以達成節能減碳的目標。

Recently, greenhouse effect has made the global climate change and seriously threatens to human survival; therefore, global warming and “Energy Conservation and Carbon Reduction” have become global major issues. Many countries have asked companies to provide carbon footprint information of products. This research first identified services for the carbon footprint information system by utilizing the concept of service oriented architecture (SOA), and then designed the system to meet supply chain requirements for small-median sized business. This system could analyze and evaluate carbon footprint of products for the supply chain companies. The services with flexibility in the system could cope with environment changes and help enterprise to rapidly response to the changes. Google cloud environment was used in this research as the services development and deployment platform. A carbon footprint service App can be downloaded in the Google cloud; therefore supply chain partners could input carbon footprint data by the services and share information with each other in the cloud. With high availability, flexibility, and scalability of the system, this system helps supply chain partners to decrease data processing time and communication time. Supply chain partners could develop carbon reduction alternatives together more smoothly.
