低碳都市評估指標系統之建構與分析

Research on Low-Carbon City Indicator System

都市為人類活動高度集聚之處，不僅是人口、建築、交通、工業、物流的集中地，同時也是高耗能、高碳排放之處（Kennedy et al., 2011），都市過量的CO_2排放是造成全球暖化與氣候變遷的主因。面對此等威脅，全球多數的政府，雖相繼以低碳都市作為發展訴求，但不少卻缺乏相對應適合該國或該都市特性之評估指標系統。因此，故本文以低碳都市為主題，根據低碳都市的內涵、理念與目標，研撰適宜之評估指標系統，透過因子分析定權法進行評估指標的擇取，藉此評估台灣各縣市的低碳發展狀態，並將台灣各縣市劃分群落，以提供作為未來都市規劃之參考。根據實證結果顯示，低碳都市評估指標系統，包括「經濟及財政狀態」、「資源消耗」、「環境保育及健康發展」、「地區發展」、「社會狀態」等5構面，共25個指標。而台灣各縣市在低碳發展的綜合表現上，以台北市的狀態最佳，而以彰化縣表現最差。 Cities are not only the high concentration sites for human activity, but also the place for high carbon emissions. In addition, the excessive CO_2 emission from city is one of the main causes of global warming and climate change. Facing the situation, most city governments in the world have set up low-carbon urban development as goal, but lacked the corresponding evaluation indicator system to measure it. Therefore, this paper is to establish the appropriate indicator system of low-carbon and intelligent city by factor analysis rating method, and evaluate the status of low-carbon and intelligent cities within the Taiwan domain. According to the results, there are five aspects for low-carbon cities: 1) economical and fiscal status, 2) and resource consumption, 3) environmental conservation and healthy status, 4) local development and 5) social status. Based on the comprehensive performance of the low-carbon city indicator system, Taipei City shows the best performance, whereas Changhua County shows the worst performance.
