A new approach to environmental-performance evaluation

This paper proposes a new approach to environmental-performance evaluation (EPE) with consideration for multiple types of environmental management systems (EMSs) for establishing a Plan-Do-Check-Act (PDCA) management cycle in the system. First, we summarize the background of the environmentally conscious society and manufacturing. Then, ISO14001 is explained as one of the useful approaches in realizing the environmental conscious management system. Finally, we suggest the new approach to EPE using data-envelop analysis (DEA). In this approach, we determine the input and output factors to obtain the performances of each EMS and compare the performances of the same type of companies using DEA. The result is used as information to maintain the continuous improvement in the system.
