Development of Eco-Efficiency Index by Emergy Analysis

The increment of quality of life as well as the concern to the environment makes the consumers request the product which is friendly to the environment. Company puts a lot of effort to shift its operation structure and technology more efficiently, therefore high efficient, improved, alternative products have been developed. Studies on eco-efficiency have been done by others using financial value of product which can not show the real value of the product. In this study, Eco-Efficiency Index based on emergy analysis, defined as Eco-Efficiency Index(EEI) = (Efficient Use of Resource(EUR) x Service Intensity Ratio(SIR) x Durability(DUR) x Recyclability(REC) has been developed to evaluate eco-efficiency based on eco-efficiency concepts and conditions declared by WBCSD. This study also applies Eco-Efficiency Index on different types of vehicle, electrical power plants and manufacturing industry and assessment of Eco-Efficiency Index by comparing with other eco-efficiency index. As a result object with more services and less goods came out to be the most eco-efficient object. This study also propose the use of Eco-Efficiency Index to help consumers to make green purchasing decisions and to help policy maker to make green policy decisions.
