| 中文摘要 | 全球氣候變遷下,極端氣候情形加劇,各國針對溫室氣體的排放已加強制約,目前我國 農業部提出將於2040年提前達成淨零排放之目標,其中農田水利設施改善工程屬於減量範疇 之一。本研究以四張犁分線改善工程為例,應用 PCCES 系統,分別以設計階段及竣工階段時 之工項數量採用排放係數法計算其碳排放量,並針對碳排放量較高之工項提出減碳策略。研 究結果顯示本工程碳排放量最高之工項為210kgf/cm2預拌混凝土,若以飛灰與爐石粉替代10%, 將可使工程碳排量減少6.5%。此外,本研究認為農田水利工程部分工項無法對應於 PCCES 資 料庫中既有工項,僅能使用經費碳排係數進行碳排量計算,此狀況將造成碳排量的計算結果 產生誤差,日後若能改善此部分,將有助於提升碳排放量計算的準確性。 |
| 英文摘要 | Global climate change intensified extreme weather events, leading to stricter international regulations on greenhouse gas emissions. Taiwan’s Ministry of Agriculture set a goal to achieve net-zero emissions by 2040, with the improvement of agricultural water conservancy facilities identified as one of the key mitigation policies. The study used the Sizhangli Irrigation Canal Improvement Project as a case study and applied the PCCES system to estimate carbon emissions at both the design and completion stages using the emission coefficient method based on the quantities of construction items. Carbon reduction strategies were proposed for items with higher emission levels. The results show that the construction item with the highest carbon emissions is the 210 kgf/cm² ready-mixed concrete. A 10% substitution with fly ash and slag powder is estimated to reduce the project’s total carbon emissions by 6.5%. Moreover, the study found that certain construction items in irrigation and drainage engineering cannot be matched with existing items in the PCCES database, and the calculation must rely on the expenditure-based carbon emission factor, which potentially causes estimation errors. Addressing this issue in the future would greatly improve the accuracy of carbon emission assessments in similar projects. |
