中文摘要	本計畫除依據IPCC 2006指南更新我國2020年及2021年環境部門(Waste Sector)溫室氣體排放量及精進清冊統計外；亦因應部門減量之需求，規劃減量路徑，透由行動方案落實以達成目標。本年度主要工作成果如下。更新2022年及2023年版環境部門清冊數據，2021年環境部門總排放量為2,679.2千公噸CO2e，已較基準年2005年下降63.4%，惟較2020年上升2.9%，主因焚化排放量增加。部門排放源以污(廢)水處理為大宗，占部門排放58.8%，排放氣體則以甲烷為主占67.5%。另，比較我國與國際廢棄物部門之排放趨勢及人均排碳量，彙整英國、瑞士、瑞典、日本及加拿大之2023年清冊報告(National Inventory Report, NIR)，結果顯示減少掩埋處理量為各國減排關鍵，而我國之人均碳排放量0.11噸CO2e/人相較各國低，僅高於瑞典。環境部門減量推動工作廣泛，部門清冊報告中列入之排放源無法涵蓋所有執行成果，為彰顯環境部門因應氣候變遷之減量工作成果，本計畫整合環境面向，針對生質能及廢棄物循環再利用推動進行減碳效益評估，2021年及2022年分別為571.6及639.0 ktCO2e，其中以塑膠回收與使用SRF再利用之減碳效益最大。另，本計畫針對我國24座大型焚化爐歷年之排放量及排碳強度進行分析，排放量主要受垃圾組成影響，且和塑膠比例呈現正相關，2022年因廢棄物塑膠平均比例達31.8%，使排碳強度達至1.14 kgCO2e/度，其中以內湖廠、嘉市廠及崁頂廠之排碳強度較高，主要係發電量較低所導致。除規劃部門減量路徑，為降低部門主要排放源之污(廢)水處理排放及配合環境部門第二期溫室氣體排放管制行動方案推動措施，辦理污(廢)水處理廠沼氣回收經驗交流會議，提高專責人員對厭氧處理操作效率之認知及增設相關設施意願。另，考量國內已有不少污(廢)水處理廠具沼氣回收系統或正在規劃中，蒐集沼氣回收相關數據可將其減量效益反映於國家清冊中，亦規劃沼氣回收申報平台並針對平台規劃進行跨部門協商，透過跨部會共同努力，以即時掌握排放及減量資訊。

摘要	The project was to compile and update the emissions of Waste Sector in 2020 and 2021 using the recommended methodologies in 2006 Intergovernmental Panel on Climate Change Guidelines for National Greenhouse Gas Inventories (IPCC 2006 Guidelines). In addition, planning the long-term roadmap of Waste Sector based on the demanding of carbon reduction. The main achievements of the project were as follows. Update the emissions of Waste Sector from 1990 to 2021. According to the result, the emissions of Waste Sector in 2021 was 2,679.2 ktCO2e, which had declined 63.1% compared to the baseline year, while increased by 2.9% compared to 2020 owing to incineration. The emissions of domestic and industrial wastewater treatment are the largest contributor from the Waste Sector, accounting for 55.8%. Gases from the Waste sector was mostly methane, accounting for 67.5%. In addition, to compare the emissions trend and per-capita carbon emissions of our country with other countries, analyzed five National Inventory Report (NIR). The results showed that decrease the waste amount in landfill is a major carbon reduction strategy for countries. The per-capita carbon emissions of Taiwan was 0.11 kt-CO2 eq, only higher than Swedan. The dimension of Waste sector’s carbon reduction strategy is board, to show the accomplishment complete, the project evaluated the carbon reduction from bioenergy and waste reuse. The results showed that 571.6 and 639.0 ktCO2e were reduced in 2021 and 2022, respectively. Among of all, recycling plastics and use SRF were major contributor. In addition, the project analyzed the carbon intensity of 24 incinerators in Taiwan. The results showed that the carbon intensity rise to 1.14 kgCO2e/kwh in 2022 due to the higher plastics ratio in treated waste. To reduce the emission of wastewater treatment and implement the reduction strategy in waste sector, seminar was hold, aiming to share the experience of biogas recovery in domestic and industry wastewater treatment plants. Besides, to investigate the information of biogas recovery in domestic and industry wastewater treatment plants, the project proposed the mechanism of biogas recovery data gathering. Also held a cross-department meeting to discuss the possibility of the mechanism.
