2.5.2 Product Management Life Cycle Assessment (LCA) LCA is a tool to improve products and manufacturing process and reduce pollution. It helps decision makers to become involved with more environmental aspects. The steps to conduct LCA includes: Scope Definition, Inventory Analysis, Impact Assessment, and Result Interpretation. In 2005, UMC authorized the Industrial Technology Research Institute (ITRI) to implement a Life Cycle Assessment in each fab. The results of such an assessment would help UMC to meet the Ecological Design Directive (ErP Directive) vis-à-vis its products, understand the impact on the environment caused by customer products manufactured at UMC, and develop improvement plans. From raw silicon to chips, investigations were conducted targeting energy consumption, materials, and pollutants of each customer product. Through the evaluation of environmental impact on the entire supply chain and manufacturing processes, the impact on the environment resulting from products is clarified and the result of evaluations is used as a reference for the environmental management system. The assessment results are open to the public and can be provided for reference upon customer request. According to inventory results, environmental impact is greater from manufacturing rather than from suppliers. As a result, UMC continues to improve its processes, reduce resource consumption and bulk materials, with the goal of minimizing environmental impact over time. Life Cycle Assessment Process 46
