However, there is still limited information on the emission quantities of the pollutant and the usage of energy resource for new industries such as the TFT-LCD industry. In this research, the Environmental Performance Indicators (EPIs) was established according to the ISO14031 Environmental Performance Evaluation for TFT-LCD industry. A total of six EPIs were selected and their values were calculated by generation so that the trend of each EPI can be applied for effectively control the usage of utilities and resources and the emission of pollutants for new generation plant. The six EPIs include water consumption, electricity and energy consumption, waste production, CO2 equivalent emission, waste acid gas emission and raw materials usage indicators. The results showed that water, electricity, energy consumption, CO2 equivalent emission and waste production are decreased as the TFT-LCD fabs step into a newer generation. For the same generation fab, its utility consumption and waste production is also decreased by year. This means that the TFT-LCD industry is toward a better environmental performance. However, the inorganic acid gas emission and raw materials index have no clear trend so far and they require more data to be clarified in the future.
