| dc.description.abstract | In recent years, global climate anomalies caused by greenhouse gases have become the leading issue in the world, in which the reduction of carbon dioxide emissions has become the common issue worldwide. Taiwan is a non-agreement country and currently has no responsibility in greenhouse gas reduction. However, considering that the industry development in Taiwan is mainly export-oriented, it is necessary to apply measures in order to reduce the pressure from the international greenhouse gas reduction (GHG) towards the industrial supply chain in the future; The responsibility lies in the manufacturing industry in “Thin film transistor liquid crystal display” (TFT-LCD), one of the projects in the Two Trillion and Twin Star Development Program, which is to study and analyze how to increase energy efficiency and reduce emission. Although there are currently no relevant domestic regulations of prohibiting perfluorocarbons (PFCs) emissions, the main source of PFCs comes from the optoelectronic semiconductor industry, where the industry had continually installed local scrubber treatment at the emission end since 2003, to control PFCs emissions. In the feasibility study of the optoelectronic industry with the Voluntary Carbon Standard (VCS) reduction project for PFCs waste gases, the beneficial reduction effect in relative to the baseline scenario has an “additional” effect, and the reduction plan also meets with the eight principles in substantial, measurable, permanent, additional, having independent verification, unique, open and transparent, and conservative. It is therefore possible for the optoelectronic industry to carry out the VCS PFCs reduction project, in which the reduction achievements in the optoelectronic industry are to be quantified to receive international recognition. This can be used to participate in the future international trading in carbon market businesses, and to enhance industrial competitiveness and achieve sustainable development as goal. In addition, the current emission reduction technologies include chemical alternatives, detecting technologies, process optimization, recycling and pipe end treatment, evaluation in cost of investment, international law control, product life-cycle analysis, damage reduction of emission set-up costs and other factors to conduct a comprehensive beneficiary analysis. Although pipe end damage treatment is not the best choice, it is currently the most established and cost-effective method of dealing with PFCs emissions.
