The City of Calgary declared a climate emergency on November 15, 2021 and is now accelerating City-wide timelines to reduce greenhouse gas emissions (GHGs) and advance climate adaptation and mitigation priorities. In response, Calgary Transit is underway with a Fleet Electrification Planning Study, supported by WSP’s Transportation and Infrastructure Advisory Services. The Project would see the replacement of internal combustion engine buses with battery electric buses (BEBs) along with electrification planning and infrastructure upgrades at three garage facilities.
This CRRA has been completed to identify, assess, mitigate, and manage risks associated with climate change during the design, operation, and maintenance of the Project. Five system categories were assessed including built and charging infrastructure, fleet assets, the environment, and people. Risk scores were evaluated for all impacts and for each time period. The maximum risk score among the time periods determines if a resilience recommendation is provided. The assessment resulted in 16 impacts with a maximum risk score of medium, 85 impacts with a maximum risk score of high, and 6 impacts with a maximum risk score of extreme.
