A methodology for weighting the environmental factors of ISO 14001-a case study on the port of Shanghai, China

This paper illustrates the environmental factors critical to the successful implementation of ISO 14001. The analytic hierarchy process (AHP) methodology was applied to find out the relative weights and priorities of these environmental factors. With the combination of the methodology of the AHP and the environmental factors listed in ISO 14001, a case study has been carried out on the port of Shanghai. The results of the study indicate the order of importance of the critical environmental factors of Shanghai Port.
