Environmental management system (EMS) has proven to be very effective in providing railways with solutions to environmental problems. After the investigation and analysis of the EMSs in about 20 organizations, including those in the railway industry, it was found that one of the most important factors in establishing them are the methods of environmental impact estimation. This paper discusses methods used in a wide range of organizations. On the basis of the results, we have been able to propose a new environmental impact estimation equation that is applicable to a number of industries, including railways.
