Disponible en CD en formato PDF Transcripción del abstract original del autor: This report considers the example of energy-use systems for urban business space conditioning, and describes the method we developed to comprehensively assess environmental impact based on the concept of life cycle assessment (LCA). Using a distance-to-target weighting method, which is one integrated assessment method for multifaceted impact, we clarified the structure of broad-ranging environmental impacts of business space conditioning systems and demonstrated an appropriate assessment method for environmental impact and the application of this method. As for the effectiveness of environmental protection efforts conducted by Osaka Gas through its business activities, we have assessed the performance of CO2 emissions reduction using the LCA method. As a result, we have found the following facts: non-excavation technique reduces CO2 emissions by about 50%; a comprehensive road waste recycling system could cut approximately 33% of CO2 emissions; gas equipment recovery and recycling activities conducted by Osaka Gas reduced CO2 emissions by approximately 64%.
