摘要


本研究以網通產品為實例,進行網通產業之產品生命週期評估及碳足跡計算。主要之研究對象為網通產品之數據機,藉由產品類別規則(PCR, Product Category Rules)的制訂,展開產品生命週期盤查,將產品進行物理性拆解,分析產品元件清單(BOM, Bill of Materials),並引用生命週期評估軟體(SimaPro)次級資料庫的物質流資料,模擬問卷調查各供應鏈廠商之能資源投入、污染物排放、生產製造、配銷、使用及廢棄物處理等數據,進行產品生命週期評估及碳足跡計算之研究。最終闡釋分析網通產品,在生命週期過程中之投入與產出,對環境所造成的全球暖化與能源耗損的衝擊,並製作產品碳足跡宣告。 本研究運用SimaPro及Eco-Report為生命週期評估應用軟體,並採用Eco-Indicator 95、IPCC GWP 100a為環境衝擊評估方法將環境衝擊予以量化,並以ISO 14040的架構以及ISO 14067的原則要求分析產品碳足跡與能耗的結果,並加以闡釋研析,探討產品在能資源使用、原物料投入、研發設計、組裝生產等不同職掌層面,可以開發出有效降低產品碳足跡的企業流程解決方案。 分析結果顯示,早期網通產業生產的數據機,因設計採用的電子元件種類多為手動插件的製程,使得產品碳足跡在供應鏈階段,佔生命週期中最高的比例;而消費者使用階段,也因設計採用的變壓器能源轉換效率較差、缺少電源自動管理功能與消費者使用習慣等因素,使得碳足跡亦佔了很高的比例。而目前網通產業在實際生產上的製程,已大幅自動化,且產品設計上多已開發出節能方案,但在產品碳足跡的量化分析技術上,仍礙於資料庫與數據盤查的門檻過高,較無法順利推展至整個產業;因此,網通綠色產品的未來重要工程,設計上應以對環境友善為首要原則,以生命週期評估結合碳足跡量化分析的方法,提升產品能源使用效率及生態效率。

In this study, Life Cycle Assessment and Carbon footprint method was used to evaluate the case of Network & Communication Industry. The main research subject was modem product which used in network. Through the Product Category Rules(PCR) of formation to inventory modem product. Dismantling the product and analysis product components according to bill of materials(BOM). The inventory result and secondary data were calculated by SimaPro, software of Life Cycle Assessment, to evaluate the environmental impact of modem product. In the end of interpretation of broadband equipment, the result shows the impact of global warming and non-renewable energy consuming. SimaPro and Eco-Report software was used in this study, Eco-indicator 95 and IPCC GWP 100a was the Life Cycle Impact Assessment method to quantify the environmental impact of broadband equipment product. This study also take ISO 14040 framework and ISO 14067 principle to calculate carbon footprint and energy consuming. The interpretation of this result to explore the use of products in energy resources, raw material inputs, R & D, assembly production etc. in different area, which developed the process by enterprise to cut down the carbon footprint of products. The result shows that the earlier network & communication product take Dual Inline Package(DIP) process to assembly electronic component would let the CFP higher than other LCA stage. In use stage, the transformer of low energy conversion efficiency, lack of power auto-management and bad custom also make CFP been higher than other stage. Network & Communication Industry have been introduced atuo-production lines, which developed varies of solution in energy saving. However, the access of database and inventory was remaining the gap to promote carbon footprint analysis in whole industry. Therefore, most important of green products should base on environmental friendly in the future. Which need to Integrated Life Cycle Assessment and carbon footprint quantification analysis result to improve product energy using and eco-efficiency.
