摘要

全球暖化與氣候變遷導致近年來各地環境變化與災害，成為現今最具探討的議題。為了遏止全球暖化與氣候變遷，溫室氣體管理之議題已在世界各地廣泛受到重視，並已逐漸成為世界各國政府施政之重點。行政院於2008年6月發布「永續能源政策綱領」，提出永續能源政策的推動綱領，推動全民節能減碳運動，宣導全民朝「一人一天減少1公斤碳足跡」努力。因此，各大學也將「節能減碳」列為大學永續經營的一項重要議題，並從上而下積極投入相關工作。為瞭解大學內教學、研究、活動等過程中排碳的比重，從2008年貣教育部開始推動大學校園溫室氣體盤調查。本研究藉由朝陽科技大學2010年之溫室氣體盤查經驗，依據營運邊界及京都議定書所規範的CO2、CH4、N2O、PFCS、SF6及HFCS等6大類進行盤查、登錄及分析，探討溫室氣體盤查之作業程序。結果顯示，該校溫室氣體排放屬範疇一的排放量為661.71 CO2e公噸/年、範疇二的排放量為8,341.00CO2e公噸/年、範疇三則為4,234.42CO2e公噸/年。由盤查結果發現，大學校園中溫室氣體的最大排放源為電力使用，占整體排放的63.01%；教職員生通勤工具與外包場所排放的溫室氣體次之，所占的比較也高達31.99%；其他（包括燃油冷媒交通用油及化糞池等）傴占整體排放量的5.00%。為研究以校內綠化植樹進行碳中和（carbon neutral）的可能性，本研究也進行校區樹木的碳吸收量，結果顯示，廣達55公頃的全校綠地每年的二氧化碳吸收量為524.41公噸，傴能中和校園（範疇一及範疇二）5.8%的溫室氣體量；若同時將範疇三列入，亦傴能中和掉3.9%的溫室氣體。由此可知，要有效達成校園節能減碳的目標，頇從提昇設備使用效率、擴大再生能源運用以及改變師生對能源的使用習慣等面向，同時多面向著手，始可達成目標。

Global warming and Climate Change make environmental changes and disasters over recent years, these had become the most discussed issues today. In order to curb global warming and climate change, greenhouse gas management issues have been taken widely around the world, also has gradually become the focus of government policies around the world. In June 2008, Executive Yuan released "Sustainable Energy Policy Framework ", to promote the national carbon reduction campaign, and advocating all the people, "one day reduced 1 kg of carbon ". Therefore, universities will list "carbon reduction" as an important issue in sustainable management of the university, and the relevant departments will start to investigate the related work from head to toe. To understand the proportion of carbon emissions during the university teaching, research, activities etc., the Ministry of Education began to promote the campus greenhouse gas (GHG) investigation in 2008. In this study, by the greenhouse gas inventory experience in 2010, according to the operational boundary of Chaoyang University of Technology and six categories of GHG regulated by the Kyoto Protocol including CO2, CH4, N2O, PFCS, SF6
III
and HFCS, GHG emissions inventory was conducted and investigated. The results show that the emission of GHG in scope I is 661.71 CO2e tonnes/year, scope II are 8,341.00 CO2e tonnes/year, scope III was 4,234.42 CO2e tonnes/year. The results show the largest source of GHG in the inventory is electricity (about 63.01% of total emissions).
Commuting emission by employees, teachers and students plus emission from operation of outsourced places is the second largest source of GHG (about 31.99% of total emissions). Others sources including fuel oil, refrigerant, transport and septic tanks, etc. accounted for only 5.00% of total emissions. The study also investigated campus greening and tree planting for carbon neutral and the possibility of campus trees for carbon uptake. The results showed that the carbon dioxide absorption capacity in wide green space of 55 hectares of the school is 524.41 metric tons per year, can only neutralize 5.8% of GHG (Category I and Category II). If Category Ⅲ included in the same time, it can only neutralize 3.9% of GHG. By adopting the strategies of improving equipment efficiency, expanding renewable energy applications, and changing the energy use habits of teachers and students, the campus can get effective carbon reduction.
