Abstract

The objective of this research was to map out the greenhouse gas (GHG) footprint of Ontario transit agencies. A system-by-system GHG emissions model was developed to determine which transit agencies are low, medium, or high emitters based on the metric tonnes of carbon dioxide equivalent (CO₂e) emitted from mobile sources. A score card was created based on four preliminary indicators: (1) CO₂e per passenger, per revenue vehicle kilometer; (2) CO₂e per passenger, per service area density; (3) CO₂e per vehicle, per revenue vehicle kilometer; and (4) CO₂e per vehicle, per service area density. This score card provides a relative metric to compare the GHG emissions of different transit agencies which can be used as an audit standard for quantifying comparative CO₂e reductions. The results indicated that one-third of transit agencies operate in the “A” grade range, while the remaining agencies received grades of “B” to “E”; thus, demonstrating the potential for utilizing Green Funds in different jurisdictions to advance technology and ridership solutions aimed at GHG emissions reduction to achieve climate change objectives.

摘要

这项研究的目的是绘制安大略省交通机构的温室气体 (GHG) 足迹。开发了一个系统的温室气体排放模型，以根据移动源排放的公吨二氧化碳当量 (CO ₂ e) 确定哪些交通机构是低、中或高排放者。计分卡是根据四个初步指标创建的： (1)每名乘客每公里收费车辆的CO _{2 e；}(2)每名乘客、每服务区密度的CO _{2 e；}(3)每辆汽车每公里收入的CO _{2 e；}(4) CO ₂e 每辆车，每服务区密度。该记分卡提供了一个比较不同交通机构的温室气体排放量的相对指标，可用作量化比较 CO ₂ e 减少量的审计标准。结果表明，三分之一的公交机构在“A”等级范围内运营，而其余机构的等级为“B”到“E”；因此，展示了在不同司法管辖区利用绿色基金来推进旨在减少温室气体排放以实现气候变化目标的技术和乘客解决方案的潜力。
