There is perhaps no greater challenge to the modern world than that of climate change. Greenhouse Gases (GHG) like carbon dioxide (CO2), are being emitted at higher than ever levels, becoming trapped in the atmosphere and affecting global temperatures—leading to what is known as climate change. In Canada, the burning of fossil fuels is one of the most significant sources of GHGs. According to Environment Canada, total national GHG emissions have risen 18 per cent, or 726 megatonnes of CO2 equivalent, above their 1990 levels. 1 This increase is largely attributed to the transportation industry, which contributes 23 per cent of Canada’s total GHG emissions annually.
