摘要:	世界各國對於溫室效應問題影響地球環境已關注許久，在2009年哥本哈根會議中延續京都議定書，列舉開發中與已開發國家短、中、長期溫室氣體排放減量目標。行政院公共工程委員會亦於民國97年所公告之政策白皮書中列出數項推行政策，其中一項重要項目為減少全國二氧化碳排放量，預定2016年至2020年間排放量回復到2008年的排放量。過去研究中，受限於評估範圍對於營建廢棄物最終處置無明確方法加以評估，營建再生產品減量效益生命週期也僅針中間製造與運輸部分加以考量，而由於再生產品碳排放量需要額外處理方式，因此與天然產品碳排放量差距不甚明顯，以致營建再生產品減碳效益無法凸顯。而目前世界各國對於各種不同產業將開始推行碳稅制度，對於高碳排放產業將提高賦稅金額。營建產業有許多項目皆屬於此範圍內，因此對於碳排放與盤查之需求與完備將會是未來必備的工作之一。本研究希望將此部份盤查更為完善，以利未來相關業者有推動減量意願，也減少推廣營建再生產品阻力。本研究參考2006年IPCC (the Intergovernmental Panel on Climate Change)研究報告之評估模式，提出製造營建產品中，對於前段天然資源開採與末端土地掩埋並量化碳排放與碳逸散之評估方式提出計算模型，使營建產品碳排放能完整評估，研究結果顯示每使用一立方再生骨材對於資源與土地節用之減碳效益為31.29（Kg-CO2/m3）。 The global warming raises potential environmental problems which people never focused in last 10 years. In The 2009 United Nations Climate Change Conference , commonly known as the Copenhagen Summit. According to the Kyoto Protocol, a framework for climate change mitigation beyond 2012 was to be agreed there. Public Construction Commission, Executive Yuan impetus several Policies in 2007,which can mitigate or reduce the climate change. One practice policy is limiting industry carbon dioxide emissions in Taiwan. It is an important goal to scheduled from 2016 to 2020 between the emissions back to 2008 emissions. Life cycle assessment studies of construction products limit by final disposal did not have a specific procedure to assess effectiveness of mining and landfill. Therefore, normal product’s carbon emission only consider transportation and manufacturing. In this situation, reusing products will have more carbon dioxide emissions than normal products. This result runs counter to general sense which reusing products can reduce carbon emission. This study is based on carbon footprint guidelines and IPCC (the Intergovernmental Panel on Climate Change)to assess carbon dioxide emissions in mining and landfill stages. After collecting related information, this study through research methods, and establish a translating model for soil carbon storage to carbon dioxide emissions.
