摘要

由於人類文明的發展對於地球的環境改變造成許多不可逆的問題，在這些問題中，全球暖化是目前最關注的問題。為了降低溫室氣體排放量，國際團體積極推動企業要設法開發低碳產品，及低碳供應鏈網路。因此許多企業紛紛主動盤查產品的碳排放量，申請並驗證碳足跡標籤，一方面希望揭露溫室氣體排放量，設計低碳產品，減少環境衝擊；另一方面希望提升企業形象，增加銷售通路，提高產品銷售量。在台灣，許多企業主動申請碳標籤，以生命週期的範疇計算碳排放量，希望能夠找出產品設計的減碳機會，重新設計產品，降低產品之碳排放量。然而，由於產品的減碳範疇較廣(涵蓋供應鏈的眾多供應商)，且設計的改變也會造成產品成本的改變，因此許多企業雖然揭露其產品的碳資訊，卻因為缺乏一套有效的供應鏈低碳網路評估系統，而無法進行下一步的減碳分析，失去企業揭露碳足跡資訊的目的。
本研究為了協助企業設計低碳產品，希望開發一套供應鏈低碳網絡評估系統，分析供應鏈網路的減碳機會。研究中，將蒐集與分析供應商的零組件與運輸方式的碳排放量與成本資料，利用多目標決策法與正規化約束法，從眾多的減碳機會中，找出可行最佳的減碳方法。企業將可利用此研究結果，與供應商共同評估與討論，在產品設計階段時找出成本較低且環境衝擊較低減碳方法，並提供給企業參考，達成企業之減碳目的。

Global warming is the most concerned issue for recent years. The development of human civilization caused many irreversible influences to the environment. In order to reduce greenhouse gas emissions, international organizations actively promoting the development of low-carbon products and low-carbon emission supply chain network. Therefore, many companies have active inventoried carbon emissions, applied and verified the carbon footprint label of products. On the one hand, they want to reduce environmental impact by exposing greenhouse gas emissions and low-carbon products designing; on the other hand, they want to promote the corporate image so that their sales volume of products could be rising up. In Taiwan, many companies take the initiative to apply carbon label. They want to find out some opportunity on products design stage, to make lower carbon emissions by carbon emissions calculation of the scope of life cycle. And so that they could by means of redesign the products to reduce carbon emissions of products. However, because the carbon reduction of products has a wider scope and it could cover many suppliers in the supply chain. In addition, the change of products design could also make changes to products costs. Due to above reasons, although many companies expose carbon information of their products, but because of the lack of an effective low-carbon supply chain network evaluation system, which can not execute further analysis of carbon reduction. Obviously, it loses the purposes that companies expose the carbon emissions information.
In this study, in order to help companies design low-carbon products, we hope to develop a low-carbon supply chain network evaluation system to analyze the carbon reduction opportunities of supply chain network. We collect and analyze the components, the transport carbon emissions, and the cost data from suppliers. Using multiple objective decision making analysis method and normalized normal constraint method, to find the optimal solution from numerous carbon reduction opportunities. After the joint assessment and discussion with suppliers, companies will be able to use this study result to identify the carbon reduction methods which is lower environmental impact and lower cost in the product design stage, in order to achieve the purpose of carbon reducing.
