The sustainable development is a key issue in the field of economy, culture and society. The national environmental production system has been established to reduce environmental impact and to foster the environmental-friendly industry. Recently, life cycle assessment (LCA) has been applied to evaluate the environmental performance of a product through its life cycle from resource to disuse. The LCA method can be utilized effectively to improve environmental problems and to prevent contamination instead of end-of-pipe treatment. The railway is the most environmental-friendly transportation system compared to others. However, the effort to minimize the environmental impact of railway should be continued to keep its role as core public transportation. For electric motor units (EMUs), their demand will be increased continuously due to their speed and punctuality. In this research, life cycle inventory (LCI) database was established for main parts of EMU to assess and improve EMUs’ environmental performance. The main materials with each part of EMU were chosen and simplified LCA was performed to evaluate environmental impact quantitatively. All of results in this study were based on 1 car of T-car (bogie, car-body and interior panel). This research provides not only the result of LCA for each phase but several functions such as automatically computing of total weight, comparing environmental index and assessment results according to impact categories, figuring out some key issues and preparing a report the results.
