摘要

隨著氣候變遷日益嚴重，教育民眾減少其碳足跡變得愈來愈重要。目前各國政府除了針對主要之排碳源進行管制外，亦希望藉由低碳社區的發展，進而提高減碳之效益，而其中碳足跡計算器扮演著讓民眾可以了解自身排碳量的重要角色，其計算結果可促使民眾改變高排碳量之行為，除了可進一步落實低碳生活，亦富有全民教育之意涵，朝低碳社會之目標邁進。碳足跡計算器主要發展於歐美國家，我國目前雖已開發出數個碳足跡計算器，然不論於計算功能或資料庫之完整性，相較於國外之碳足跡計算器皆略顯不足，因此本研究之目標在於開發出一個符合台灣生活型態、且兼具完整性之碳足跡計算器架構。但由於碳足跡計算器之計算層面廣泛且計算項目繁多，其中亦有可能有重覆計算之問題，因此本研究透過碳足跡計算器實例蒐集與彙整，初擬出碳足跡計算器評估架構，且為求該架構之完整性，故本研究採用廣泛應用於架構確認之評估方法-模糊德爾菲法，透過兩階段之專家問卷，整合各方專家之不同見解，完成我國碳足跡計算器之架構。研究結果包括發展出一個具完整性之碳足跡計算器架構，包含住、行、食、商品及服務與綠色行為五大構面與二十一項準則，可供未來建置我國碳足跡計算器作為參考之依據；另透過碳排放係數蒐集與分析，發現我國目前現有之碳排放係數資料庫之內容仍屬缺乏，未來應逐步擴充我國碳排放係數資料庫，使其更趨完整，進而建構出更符合我國生活型態之碳足跡計算器。

With the rising concern on the deterioration of climate change, how to educate general public to reduce their carbon footprints become more and more important. Currently, governments of every country focus not just on controlling the main emissions sources, but also try to enhance the efficiency of carbon reduction through the development of low carbon communities. Hence, a suitable carbon footprint calculator play a crucial role in educating general public to understand their own carbon emissions and to further change their living behaviors. In Taiwan, although several carbon footprint calculators have been developed, none of them is adequate in terms of functions and completeness of the database. Therefore, to develop a carbon footprint calculator framework conforming Taiwanese living style and with completeness becomes the goal of this study. After analyzing various carbon footprint calculators, an evaluating hierarchy for Taiwan’s carbon footprint calculator was proposed. In order to ensure the effectiveness of the hierarchy, this study applied the Fuzzy Delphi Method to collected experts’ opinions on the framework. After two rounds of FDM questionnaires, the framework of carbon footprint calculator to be used in Taiwan was finalized. The proposed carbon footprint calculator framework consists of 5 dimensions (including household, transportation, food, commercial goods/services and green behaviors) and 21 indicators. In addition, through collecting and analyzing the carbon emission coefficients, this study discovered that most of carbon emission coefficients for calculating carbon footprints are missing in Taiwan. It is suggested that in order to strive to the low carbon society, a database which consists of accurate and complete carbon emission coefficients should be established in the future.
