| 摘要: | 隨著科技的不斷進步，也讓我們的生活不斷的更加便利，但也同時加劇了環境汙染的問題。全球正面臨著氣候變遷以及環境暖化的嚴重挑戰，研究指出因人類活動而排放的溫室氣體是全球暖化、氣候變遷具有密切的關連性，進而凸顯環保問題的重要性。因應氣候暖化帶來的災害，許多國際組織開始制定管制碳排放相關規範，例如聯合國氣候變化綱要公約，並制定二氧化碳排放減量時程。歐盟法規的推波助瀾，讓產品碳排放的要求急遽上升，企業面臨著降低經營衝擊與永續經營的新挑戰。
因此，當企業開發新產品時，必須把低碳的條件列入產品設計因子中。目前，在個案研究公司的產品，新產品開發已經在遵循ISO 14044生命週期盤查和ISO 14064溫室氣體盤查標準，對產品或服務進行生命週期評估 (LCA)。後續依照ISO/TS 14067標準計算產品的碳足跡 (Carbon Footprint，CFP)，以符合台灣的相關法規和企業的永續經營策略。
本個案碳足跡計算研究是以搖籃到大門(Cradle-to-Gate，C2G)方式，研究背光模組內零組件導光板生命週期之碳排放量。研究成果指出，其中原料取得階段的排放量為 4.588 kgCO2e/公斤，占總排放量的 91.91%，而製造階段的排放量為 0.404 kgCO2e/公斤，占總排放量 8.09%。
藉由製程的數據揭露，評估在製程中可進行的減碳項目與對策施行。研究方法為以行動研究法去進行押出製程降溫減碳實驗。研究方向工廠生產為主，另涵概工廠的廠務端的節能評估則當下不影響產品良率下，直接做改善。
最終加熱器用電下降21.8%，黑點不良率下降70%，達到企業減碳目標以及生產成本下降，企業有續經營目的。;With the continuous advancement of science and technology, our lives have become increasingly convenient, but it has also exacerbated the problem of environmental pollution. The world is facing serious challenges of climate change and global warming. Studies have shown that human activities′ greenhouse gas emissions are closely related to global warming and climate change, highlighting the importance of environmental protection issues. In response to the disasters brought about by climate change, many international organizations have begun to formulate regulations related to the control of carbon emissions, such as the United Nations Framework Convention on Climate Change, and set a timetable for reducing carbon dioxide emissions. Due to EU regulations, the requirements for product carbon emissions have increased significantly, and enterprises are facing new challenges of reducing business impact and sustainable operation.
Therefore, when enterprises develop new products, they must consider low-carbon conditions as product design factors. In the current case study of the company′s products, new product development already follows the ISO 14044 life cycle inventory and ISO 14064 greenhouse gas inventory standards and conducts life cycle assessment (LCA) on products or services. Subsequently, the product′s carbon footprint (Carbon Footprint, CFP) is calculated in accordance with the ISO/TS 14067 standard to comply with Taiwan′s relevant regulations and the company′s sustainable management strategy.
The carbon footprint calculation study in this case is based on the cradle-to-gate (Cradle-to-Gate, C2G) method to study the carbon emissions in the life cycle of the light guide plate of the components in the backlight module. The research results indicate that the emission in the raw material acquisition stage is 4.588 kgCO2e/kg, accounting for 91.91% of the total emission, while the emission in the manufacturing stage is 0.404 kgCO2e/kg, accounting for 8.09% of the total emission.
By disclosing manufacturing process data, the carbon reduction projects and countermeasures that can be implemented in the manufacturing process are evaluated. The research method used the action research method to conduct temperature reduction and carbon reduction experiments on the extrusion process. The research direction is mainly on factory production, and energy-saving evaluations on the factory service side of the factory are also included in immediate improvements without affecting the product yield.
In the end, the power consumption of heaters decreased by 21.8%, and the defective rate of black spots decreased by 70%, achieving the company′s carbon reduction target, reducing production costs, and enabling the company to continue operations. |
