A mobile source carbon dioxide (CO2) emissions inventory for the University of Central Florida (UCF) has been completed. Fora large urban university, more than 50% of the CO2 emissions can come from mobile sources, and the vast majority of mobile source emissions come from on-road sources: personal vehicles and campus shuttles carrying students, faculty, staff and administrators to and from the university as well as on university business trips. In addition to emissions from on-road vehicles, emissions from airplane-based business travel are significant, along with emissions from nonroad equipment such as lawnmowers, leaf blowers, and small maintenance vehicles utilized on campus. UCF has recently become one of the largest universities in the nation (with over 58,000 students enrolled in the fall 2011 semester) and emits a substantial amount of CO2 in the Central Florida area. For this inventory, students, faculty, staff and administrators were first surveyed to determine their commuting distances and frequencies. Information was also gathered on vehicle type and age distribution of the personal vehicles of students, faculty, administrators, and staff as well as their bus, car-pool, and alternate transportation usage. The latest US. Environmental Protection Agency (EPA)-approved mobile source emissions model, Motor Vehicle Emissions Simulator (MOVES2010a), was used to calculate the emissions from on-road vehicles, and UCF fleet gasoline consumption records were used to calculate the emissions from nonroad equipment and from on-campus UCF fleet vehicles. The results of this UCF mobile source emissions inventory were compared with those for another large U.S. university.
With the growing awareness of global climate change, a number of colleges/universities and other organizations are completing greenhouse gas emission inventories. Assumptions often are made in order to calculate mobile source emissions, but without field data or valid reasoning, the accuracy of those assumptions may be questioned. This paper presents a method that involves a survey, the use of the MOVES model, and emission factors to produce a mobile source emissions inventory. The results show that UCF mobile source CO2 emissions are larger than most other universities, and make up about 2% of all the mobile source emissions in Orange County, Florida.
已完成中佛罗里达大学(UCF)的移动源二氧化碳(CO2)排放清单编制工作。对于一个大型城市大学来说,超过 50%的 CO2 排放可能来自移动源,而绝大多数移动源排放来自道路源:个人车辆和校园穿梭巴士,接送学生、教职员工和管理人员往返大学,以及进行大学差旅。除了道路车辆排放外,基于飞机的公务旅行排放以及校园内使用的非道路设备(如割草机、吹叶机和小型维修车辆)排放也很显著。UCF 最近成为全美最大的大学之一(2011 年秋季学期有超过 58000 名学生注册),在佛罗里达州中部地区排放大量 CO2。对于本清单,学生、教职员工、管理人员首先接受调查,以确定其通勤距离和频率。还收集了学生、教职员工和管理人员个人车辆的车辆类型和年龄分布信息,以及他们的公共汽车、拼车和替代交通方式的使用情况。最新的美国环境保护署(EPA)批准的移动源排放模型——机动车排放模拟器(MOVES2010a),用于计算道路车辆的排放,UCF 车队的汽油消耗记录用于计算非道路设备和校园内 UCF 车队车辆的排放。本 UCF 移动源排放清单的结果与另一所美国大型大学的结果进行了比较。
随着对全球气候变化的认识不断提高,许多学院/大学和其他组织正在完成温室气体排放清单编制工作。为了计算移动源排放,通常会做出假设,但如果没有实地数据或合理的推理,这些假设的准确性可能会受到质疑。本文提出了一种方法,涉及调查、使用 MOVES 模型和排放因子来生成移动源排放清单。结果表明,UCF 的移动源 CO2 排放大于大多数其他大学,占佛罗里达州奥兰治县所有移动源排放的约 2%。
