Abstract
The indirect environmental impacts of industries or policies caused by the activities of
a supply chain were sometimes 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 the 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... (More)
The indirect environmental impacts of industries or policies caused by the activities of
a supply chain were sometimes 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 the 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 the semiconductor industry exhibits above-average influence and
sensitivity among its 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 the Two Trillion and Twin Star
policy were adopted. We also found that the
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 assist policy in the future. (Less)
