| 摘要: | 近年來溫室氣體造成世界各地氣候異常已成為全球問題之首，降低二氧化碳排放已是全世界共同議題。雖然我國非締約國，目前也無溫室氣體減量責任，但考量我國產業發展主要係以出口為導向，為了減緩產業供應鏈於未來可能遭遇到國際溫室氣體減量壓力，身為兩兆雙星產業發展計畫之「影像顯示」製造業有責任研析如何提升能源使用效率及排放減量。雖然國內目前沒有相關法規要求PFCs氣體不可排放，但PFCs主要排放來源為光電半導體產業，而光電業已於2003年陸續於尾氣加裝Local Scrbber處理設備，降低PFCs排放量，針對光電業進行自願性碳標準PFCs廢氣破壞減量計畫可行性之研究，其減量效益相對於基線情境具有「外加性」，且減量計畫符合實質性、可量測性、永久性、額外性、經過獨立驗證、獨特性、公開透明及保守性等八大原則，故光電業進行自願性碳標準PFCs廢氣破壞減量計畫是可行的，並將光電業減量績效予以量化獲得國際間認可，作為未來參與國際碳市場之交易使用，提升產業競爭力且達到永續發展之目標。另現有之排放減量技術有化學品替代、偵測技術、製程最佳化、回收再利用及管末處理，評估成本投資、國際法規管制、產品生命週期分析及破壞減量的排放設置成本等因素，進行综合性的效益分析，雖然管末破壞處理並不是最佳選擇，但目前卻是處理PFCs排放最成熟且最經濟有效的方法。 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. |
