Tiivistelmä
The purpose of the thesis was to compare the environmental impact of mid-range cars; Toyota corolla as a conventional car, Nissan leaf 40kWh as an electric car and a Toyota corolla modified as a Flexible Fuel Vehicle (FFV). Petrol, electricity and ethanol were the fuel types considered for these cars respectively. The environmental impact was analyzed based on greenhouse gases (GHGs) emitted during their whole life cycle. The emissions during the production phase of fuel, vehicle manufacturing, battery manufacturing and usage phase were considered. The research was conducted through literature review. Likewise, the data of emission was analyzed from the LIPASTO Traffic Emission, JEC Well to Tank report v5 and from the company’s sustainability reports.
The results were presented in the form of bar diagrams to compare the overall emissions of each vehicle and their emissions at different stages. The alternative fuel-based cars seemed to have less emissions than a conventional car. The overall emissions of both Nissan leaf and FFV were around 15 thousand kilograms of CO2eq, whereas the overall emission from Toyota corolla was around 35 thousand kilograms of CO2eq. The emissions from the Toyota corolla were about twice the emissions from Nissan leaf and FFV.
Thus, it can be concluded that the electrification of fleets and use of the biofuel cars should be promoted to meet the EU and national targets. Purchasing of electric passenger cars and conversion of conventional cars into flexible fuel vehicles can be effective measures for a significant reduction of overall emissions from passenger cars.
