| Title | Applying IO Approaches for Estimating Environmental Impacts of Industry and Policy in a Life Cycle Perspective: A case study: GHGs emission of semiconductor industry and Two Trillion & Twin Star Policy in Taiwan |
| Summary | The indirect environmental impacts of industries or policies caused by the activities of a supply chain were sometimes to be neglected although the prevention of direct impacts from industries was addressed and several measures were taken. IO approach is a powerful tool to analyze the activities in a supply chain. Industrial interdependence analysis and EIO LCA, which are IO approaches, are applied in this study to evaluate semiconductor industry and estimate the overall GHGs emission of “Two Trillion and Twin Star” policy in Taiwan. By undertaking the calculation of IO table and sectoral GHGs emission data, the level of industrial interdependence could be determined, and the increment of overall GHGs emission under the policy could be also estimated. Results show that semiconductor industry exhibits above-average influence and sensitivity among 161 sectors. Its overall GHGs emission, 46 million ton CO2e in which chemical material manufacturing sector contributes the most, is much more than its direct emission, 8.9million ton CO2e. The increment of GHGs emission would be around 10 million tons CO2e if “Two Trillion and Twin Star” policy were adopted. We also found that IO approach can not exactly reflect the reality while it has a defective assumption of fixed input structure. EIO LCA might be an appropriate tool to analyze a macro system. However, too general categorization of sectors and geographic boundary might limit the application of EIO LCA. The outcome of this research is mainly targeted for policymakers of industrial policy. The knowledge gained from the research could hopefully be assisted to draw up the policy in the future. |
