The purpose of this paper is to provide a comparative environmental life cycle assessment (LCA) of chosen internal combustion engine vehicles (ICEVs). It addresses an LCA of both petrol-fuelled and diesel-fuelled passenger cars. The analyses pertained to the carbon footprint and respiratory inorganics related to the cars in question, considered against the relevant system from cradle to grave. The comparative analysis has shown that the carbon footprint of a diesel-fuelled car is lower than that of a petrolfuelled car. However, the environmental indicators of respiratory inorganics induced by diesel-fuelled cars are higher than those attributable to petrol-fuelled cars. The main determinant of carbon footprint for the life cycle of these ICEVs is the direct atmospheric emission of carbon dioxide associated with their operation. The main determinants of respiratory inorganics for the diesel passenger cars’ life cycle are nitrogen oxide emission and car production. As for the life cycle of petrol-fuelled passenger cars, the largest share of the respiratory inorganics indicator is attributable to the car production and petrol production.
