Due to socioeconomic shifts and the need to achieve deep cuts in greenhouse gas emissions, Canada will experience an unprecedented transformation in its transportation sector. This transformation need not only mitigate climate change, but also enable community air quality benefits in an equitable manner. It is crucial that efforts to decarbonize the transportation sector be informed by the co-benefits of greenhouse gas reduction. Indeed, in Canada, 14,600 deaths per year are attributed to air pollution and the annual economic value of air pollution related health outcomes is approximately $114 billion. The recent World Health Organization announcement (October 2021) on tightening air quality guidelines further strengthens the importance of climate mitigation that improves air quality and public health. Alternative fuels, transport electrification, ride hailing, e-commerce, all carry promise for achieving climate benefits. However, the implications of these new transportation technologies and services on air quality and environmental justice are not well characterized, hindering our ability to identify win-win solutions. The proposed research program is aimed at helping Canadian industry, government, and communities, prioritise transportation innovations that will achieve low to zero emissions, while bearing positive societal impacts. To anticipate the effects of transportation innovations on climate, air quality, and environmental justice in Canadian cities and inform the transformation currently occurring in the transportation sector, the proposed research program will address knowledge gaps in 1) emission characteristics of new transportation technologies, 2) impacts of new vehicle technologies, active transportation, and altered human behavior on climate, air quality, and environmental equity, and 3) ability to monitor and track this transformation over time. Specifically, this research program has three objectives: Objective 1: Improve transportation emission inventories for greenhouse gases and air pollutants Objective 2: Enhance capability to model community-level air pollution and environmental justice under a set of long-term transport decarbonization pathways Objective 3: Measure human behavior, emissions, and air quality impacts of selected interventions and develop best practices for community engagement and participatory data collection This research program will combine generalizable long-term modelling with local intervention studies, leveraging participatory data collection methods and community engagement, to obtain place-based perspectives that enable broader learning. This program will advance understanding of transportation challenges and opportunities and promote the development of community-level data, through campus-community-government partnerships.

由于社会经济的转变以及在温室气体排放中进行深度削减的需求，加拿大将在其运输部门经历前所未有的转变。这种转变不仅需要减轻气候变化，而且还需要以公平的方式使社区空气质量益处。至关重要的是，要通过减少温室气体的共同利益来告知运输部门的努力。实际上，在加拿大，每年14,600人死亡归因于空气污染，与空气污染相关的健康成果的年度经济价值约为1,140亿加元。最近关于加强空气质量指南的世界卫生组织宣布（2021年10月）进一步增强了缓解气候的重要性，从而改善了空气质量和公共卫生。替代燃料，运输电气化，乘车，电子商务，都承诺实现气候利益。但是，这些新的运输技术和服务对空气质量和环境正义的含义尚未得到很好的特征，从而阻碍了我们识别双赢解决方案的能力。拟议的研究计划旨在帮助加拿大的工业，政府和社区，优先考虑运输创新，而运输创新将达到低至零排放，同时产生积极的社会影响。 为了预测加拿大城市的运输创新对气候，空气质量和环境正义的影响，并告知交通运输部门目前发生的转变，拟议的研究计划将解决1）新运输技术的排放差距，2）2）新车辆技术，积极的运输，积极的运输，对气候质量和环境平等和环境平等和3个环境的影响以及3.的影响和3个影响。具体而言，该研究计划具有三个目标：目标1：改善用于温室气体和空气污染物目标的运输发射清单目标2：在一系列长期运输脱碳途径中，增强了建模社区水平的空气污染和环境正义的能力。利用参与式数据收集方法和社区参与，以获得能够更广泛学习的基于地点的观点。该计划将通过校园社区政府合作伙伴关系提高对运输挑战和机遇的了解，并促进社区级数据的发展。
