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.
