The aim of this paper is to show how LCA(Life Cycle Assessment) is used as a tool to evaluate the environmental burdens associated with EMU(Electronic Motor Unit), especially one of main components, an interior panel. Thus, the LCA results are polished into the general environmental product declaration format to communicate with the industrial and institutional customers. The format includes the product information and environmental information. In the list of environmental information, profile is consisted of two major results from the LCA study. One is the inventory analysis and the other is the characterized impact results. The format shown in this paper can be the one of option to choose environmentally preferable product and suggestion aimed at the institutional consumer such as government procurement office and corporation"s purchasing department.

Industry faces a considerable challenge to meet the high demand for reduced impacts and improved environmental performance. With this current stream, railway industry launched a systematic scheme for environmental friendly EMU and its system. An assessment tool which evaluate the environmental impacts of the product through its entire life cycle has been developed. The next step to environmentally sound and sustainable product design, shortly ECODESIGN has come to be essential and necessary as well. Ecodesign requires to identify possible stakeholder requirements first. The paper illustrates way how to define stakeholder requirements in terms of environment and shows approach linking stakeholder requirements to environmental parameters.

As Kyoto protocol has been effective in 2005, the reduction of CO₂ emission is a global urgent problem. In Korea, the CO₂ emission of transportation increases continuously, which can be solved partially by the use of railroad. Therefore, it is necessary to calculate exactly the CO₂ emission of railroad through life cycle approach. In this study, the CO₂ emission of electric motor unit (EMU) was evaluated with its carboy material using life cycle inventory analysis (LCIA). Among the life cycles of EMU, CO₂ emission was the highest in the running phase. As the total weight of EMU was lowered, CO₂ emission was reduced. In conclusion, the light-weighting of EMU can reduce CO₂ emission efficiently.

Recently, the railway has been growing as the eco-friendly transport which is excellent for reducing carbon dioxide. However, the level of using tools to quantitatively and objectively evaluate the environmental performance is still low in the rail industry. Therefore, it is necessary to introduce Environmental Product Declaration(EPD) which describes the environmental performance by using Life Cycle Assessment(LCA) for evaluating the environmental impacts through entire life cycle of a product. The EPD enables stakeholders including policy makers, operation body, vehicle manufacturers and drivers and consumers to be informed about the superior environmental performance of rail vehicles.

To assess the environmental aspects of Electric Motor Unit(EMU) or services and ultimately, improve the environmental performance of EMU, a robust analytical tool is essential. Life Cycle Assessment(LCA) is a suitable evaluation method and application of LCA results for improvement is general in the various fields of industry. LCA is a systematic tool that enables to analyze environmental loads of a product and services over its entire life cycle. LCA procedures are divided into four phases, goal and scope definition, inventory analysis, impact assessment and interpretation(ISO 14040, 1997). The goal and scope definition deals with questions like why perform LCA, who are the target audiences, and what is the application of the LCA results. Life Cycle Inventory Analysis(LCIA) involves data collection and processing the collected data to generate the inventory analysis results. Impact assessment phase is to convert inventory results into the impacts on the environment. Finally, Life Cycle Interpretation is to interpret overall results of LCA and to identify environmentally significant issues. However, no cases to obtain Life Cycle Inventory(LCI)data on any components of EMU is available to data and information on such production processes is scarce. For this reason, the aim of this article is to show how LCI data is collected and built, thus it is highly recomme-nded to implement in current LCA software dealing with data collection and database.

World Business Council for Sustainable Development(WBCSD) is effort to achieve sustainable development in economic growth, environmental preservation and social development. Being this way, it is essential for developing evaluation tool which quantify to fulfill sustainable development. Eco-efficiency is one of the quantitative tools to evaluate environmental impact and economic aspect. Eco-efficiency, in general term, means creating more value of product or services with less impact to environment. It indicates as environmental impact in denominator and value of product or services in numerator. Eco-efficiency shows how much economic value reveals to unit environmental impact caused by product or service as an indicator. This study aims at developing eco-efficiency indicator of railway industry considering use stage among the entire life cycle stage of KTX and Saemaul train and also, figure out eco-efficiency value through indicator. Therethrough, it is enables to evaluate created value per environmental aspects. Since rail vehicles demands a lot of energy to transport people during use stage, the environmental impact is more significant than other lkfe cycle stages. Therefore, it quantified environmental indicator as CO2 emission and economic indicator as transportation record per a year with an annual income. This study contributes to be used as a tool for quantifying indicator of comparison evaluation in respect of rail vehicle in use stage.

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.
