摘要

限制二氧化碳排放的「京都議定書」於2005年2月16日正式生效後，宣示碳排放管制與交易的時代已然來臨。我國雖非締約國，但無法規避此一國際趨勢，仍應及早面對以降低衝擊。溫室氣體排放量基線資料為評估減量、制訂因應策略的重要參據，因此排放量盤查應為現階段首要的基礎工作。
本文首先整合國際間溫室氣體盤查規範、程序及盤查工具，再以國內溫室氣體排放量較高的一貫作業煉鋼廠為例，探討其製程、溫室氣體排放源、盤查方法、實際盤查結果及節能減量措施，同時蒐集國際同業間的盤查數據參考比較。以中國鋼鐵公司2003、2004年盤查結果顯示，CO2排放強度為2.06及2.15（噸CO2/噸粗鋼），同時期國際各鋼鐵廠的排放強度則約為1.46∼2.45。
目前國際間計算溫室氣體排放量較常使用排放係數法，而選用適當的排放係數和輸入正確的活動強度數據則攸關盤查的準確度。本文除研析排放係數來源、種類及準確度外，並探討使用排放係數法可能產生的誤差及不確定性，以為策進參考。同時建議政府未來宜研提國家層級的本土化排放係數，以期獲得較精確的國內溫室氣體排放基線資料。

“Kyoto protocol” became formally effective on February 16, 2005 for the restriction of CO2 emission, which also declared the new era of carbon emission control and trade market. Although Taiwan is not one of the treaty-wise nations with Kyoto protocol; following the international trend is inevitable. The greenhouse gases (GHG) emission data is a substantial evidence for reduction estimation and strategy establishment. Therefore the emission inventory shall be the fundamental at this current stage.
This thesis arranges primarily the international GHG inventory standard, procedure and tool, which is based on a consistent operating steel company as a case study with higher emission; thus to discuss the GHG emission source, inventory method, practical inventory result, energy reduction measures and compare with other inventory data from same business meanwhile. The 2003 and 2004 GHG inventory result for China Steel Co., Ltd showed the CO2 emission is 2.06 and 2.15 (ton per CO2/ton per steel）and the emission range from other steel company worldwide was approximately 1.46∼2.45.
The most common approach for calculating GHG emissions is through the application of generic emission factors; the inventory accuracy is chosen by proper emission factors and accurate activity data. This thesis analyzes besides the source, the type and the accuracy of emission factors, but also discusses the error and uncertainty by utilizing this method for further reference. Meantime, the objective is to propose to the government for localized emission factors at premier level in order to obtain more accurate GHG emission data nationwide.
