Abstract:	因應京都議定書將於2012到期後的新規範，各會員國於丹麥首都哥本哈根的貝拉會議中心舉行第十五次聯合國氣候變化締約國大會（COP15），以制訂因應後京都時代的「哥本哈根議定書」，明確提出2020年前的溫室氣體減量目標與相關作法。行政院確立國家節能減碳總計畫，並拍板確定未來短期減碳目標訂為2020年回歸2005年排放目標，推動「節能減碳年」；中長期以2025年回歸2000年為排放目標。振興經濟擴大公共建設投資計畫落實節能減碳執行方案要求預算必須含有至少一成的綠色內涵經費。公共工程再生材料有再生級配粒料、再生水泥混凝土與再生瀝青混凝土，取代之再生原料有廢棄混凝土、轉爐石、水淬爐石粉、飛灰與挖(刨)除料等，本研究希望藉由國內外文獻、以往相關之研究及廠商之資料建立公共工程CO2排放量資料庫，用以評估上述再生原料再利用為再生材料是否具有節能減碳效益。結果顯示除轉爐石因生產與處理據點少，在運輸上耗能相對於天然粒料高出很多，目前應用於公共工程尚不具節能減碳效益;其餘再生原料以水淬爐石粉因產量多、可大量取代水泥，最具節能減碳效益;最後以國內每年再生原料生產量與再利用率(不包含國外進口)推估公共工程使用再生材料約可減少3,490,500,000kg-eCO2(減碳)，相當於省下1,337,356,322 L柴油(節能)。 In response to the Kyoto Protocol will expire after 2012, new regulations, the Member States in the Danish capital Copenhagen at the Bella Center at the Fifteenth United Nations Climate Change Conference of the Parties (COP15), to formulate a response to post-Kyoto era, "Copenhagen Protocol" , clearly by 2020 greenhouse gas reduction targets and related practices. Executive Yuan to establish national carbon reduction total picture, and the green light to determine the future short-term carbon reduction targets set for 2020 return to 2005 emissions targets, to promote "energy saving and carbon years" long to return to 2025 emission targets in 2000. Revitalizing the economy to expand public construction investment plan to implement carbon reduction program requires the implementation of the budget must contain at least one percent of funding for green content. Public Works gradation of recycled materials have recycled aggregate, recycled concrete and recycled asphalt concrete, instead of renewable raw materials are concrete, BOF slag, slag, fly ash and dig (dig) In addition to materials of this study hope literatures from the past, related research and information on the establishment of public works Firms CO2 volume data bank to assess the regeneration Yuan Liao Zailiyongwei recycled materials with energy-saving Jian Shi Fou carbon benefits. The results show that apart from BOF slag production and processing base for less energy consumption in transportation is much higher compared to natural aggregate, currently used in public works was not a carbon reduction benefits; other renewable raw material for production of slag and more can be a lot of replacement of cement, the most carbon reduction benefits; Finally, the annual domestic production of renewable raw materials and re-utilization rate (excluding imported) to use recycled materials for public works estimated to reduce approximately 3,490,500,000 kg-eCO2 (carbon reduction), save 1,337,356,322 L of diesel equivalent (energy).
