Abstract

An efficient way to reduce CO2 emissions is the replacement of gasoline passenger cars (PC) with diesel ones. Most of the member countries of the European Union have high percentages of new diesel PC registrations, however this percentage is only 7% in Sweden. In the present work, the benefit of CO2 emitted from the new PC is studied in the case of an increased penetration of diesel PC in Sweden, for several scenarios using the current and estimated future PC sales and fuel consumption (FC). The results show that total future CO2 emissions will increase significantly and can be partially controlled by the introduction of diesel PC or the replacement of heavy PC by lighter ones.

The authorities and policy makers look for a stabilization of these emissions following, for example, the Kyoto protocol [3]. However, even if the CO2 emissions of each PC decrease, the total CO2 emissions of the transport sector increases, mainly due to the increase of passenger car fleet. As for the same driving distance, Diesel PC emit less CO2 than gasoline types, an efficient way of controlling the total CO2 emissions is the replacement of a number of gasoline PC by Diesel ones. The percentage of new Diesel PC sales is quite important in all European Union (EU) countries [4, 5], however, is less than 7% in Sweden [5, 6]. The
