Lifecycle analysis studies of electric vehicles (EVs), such as electric school buses (ESBs), indicate that the greater impacts during the manufacture of EVs are minimal compared with those avoided by petrol and diesel, which are not produced or burnt.
In the case of ESBs, several factors help to reduce the environmental impact of their manufacturing. Firstly, the majority of ESBs circulating across the country are manufactured in Canada, which reduces the GHG emissions associated with transporting the vehicles.
Secondly, when ESBs reach the end of their life and since there is a strong demand for batteries, those ESB batteries can be put to other uses or recycled, which reduces the demand for new batteries.
Finally, although this is not yet a well-developed sector in Canada, there are companies that specialize in converting diesel buses into electric models, which reduces the manufacturing footprint of ESBs (excluding the battery).
