The UN established the UN Intergovernmental Panel on Climate Change to persuade countries into signing Paris Agreement, regulating the use of energy and greenhouse gas emission by countries and enterprises all over the world. As an export-oriented economy with limited resources, Taiwan must immediately respond to the challenges caused by the potential requirements of importers that export products be produced with efficient or renewable energy. The industry should attach importance to the international trend of environmental protection and energy conservation by monitoring and reducing greenhouse gas emission, managing supply chain in a low-carbon manner and decarbonizing the supply chain, and building a complete energy system in line with international standard. Against this backdrop, this study uses the items of ISO 50001 to formulate survey questionnaires, and intends to verify whether the internal energy efficiency of enterprises imported by ISO 50001 can be improved, and whether the energy consumption and cost of enterprises can be reduced to live up fulfill the green commitment of energy conservation and carbon reduction. This study intends to adopt the indicators of the ISO 50001 management system to illustrate the importance and feasibility of the four major industries in Taiwan. Firstly, survey questionnaires reviewed by experts were formulated according to the indicators of the ISO 50001 management system, and a questionnaire survey was conducted through on four major industries: light industry, heavy industry, high-tech industry and service industry. A total of 740 questionnaires were sent out, 276 of which collected and 263 were valid ones, with a recovery rate of valid questionnaire up to 35.5% and the Cronbach α for 0.983. The main objectives of this study are as follows: (1) To understand the application of the indicators of the ISO 50001 management system to Taiwanese enterprises, including their importance and feasibility. (2) To understand the differences of the adaptability of the four industries to the ISO 50001. (3) To use IPA analysis method to understand what indicators of the energy management system should be prioritized and what should be suspended in different industries? The necessity of energy certification in light industry, heavy industry, high-tech industry and service industry is discussed, and the difficulty of imposing energy certification on enterprises is explored. Questionnaire survey method is adopted to understand and analyze the importance and feasibility of each dimension and item when ISO 50001 is imposed on enterprises for energy certification. The importance and feasibility of the major dimensions of ISO 50001 are summarized in a chart, and interview method is used to understand the results analysis of energy certification. According to the ISO 50001 evaluation, there are seven aspects for the analysis of importance and feasibility. It is found that "management responsibility" gets the highest score of 4.50 for the importance of overall evaluation, followed by "general requirements" for 4.28, "management review" for 4.21 and "implementation and operation" for 3.97, the dimension with the lowest score. Nearly all these dimensions go beyond the satisfaction degree. In the overall evaluation of feasibility, "energy policy" gets the highest score of 3.16, followed by "management review" of 3.04, "general requirements" of 3.01 and "implementation and operation" of 2.75, the dimension with the lowest score. These dimensions mostly fall around the normal degree. The feasibility of the dimension of ISO 50001 is still facing difficulty. According to IPA analysis, "general requirements", "management responsibility" and "management review" score the highest in terms of the feasibility of seven dimensions. They all fall in the first quadrant and are indicators that should be prioritized for implementation; the two indicators of "energy planning" and "implementation and operation" fall in the third quadrant, which should not be prioritized for implementation. If the items of dimensions of each industry are distributed in the first quadrant, enterprises can give priority to these items, including item 1 of “general requirements”, items 1 and 3 of “management responsibility”, items 2, 3 and 4 of “energy policy”, items 3, 4 and 6 of “energy planning”, items 2, 6 and 12 of “performance evaluation” and items 1, 2 and 3 of “management review”. If the items of dimensions of each industry are distributed in the third quadrant, enterprises can suspend the implementation of these items, including items 10, 11, 12, 14 of “energy planning”, 1, 3, 4, 5, 6, 7, 8, 9, 10, 11 of “implementation and operation”, and 3, 4 of “performance evaluation”.
