"The most of the most"-study on a new LCA method

LCA (life cycle assessment) is a quantitative method to evaluate the environmental impacts involved with a certain product over its whole life cycle by calculating the inputs and outputs of the system. However, it has some limitations: unavoidable hypothesis, incomplete data, weak adaptability and high cost etc. Consequently, several simple LCA methods came into being. In order to make the LCA method more practical, a new evaluation method named "the most of the most" is introduced in this paper, and the feasibility of it is demonstrated through case studies comparing with the traditional method.
