Abstract
This paper presents a Well-to-Wheels (WTW) analysis of equivalent carbon dioxide
(CO2eq) emissions in different scenarios of replacement of a conventional taxi
fleet by electric vehicles. Two battery electric vehicles and one hybrid
electric vehicle were used in the comparison with the conventional vehicle
fleet. A numeric model was developed to evaluate CO2eq emissions in the fuel
production, electricity supply, and vehicle operation phases. Gasoline and
sugarcane ethanol were considered as fuels for the conventional and hybrid
electric vehicles. Six scenarios of conventional vehicles replacement by
electric vehicles in the taxi fleet were evaluated. The results showed that the
replacement of nearly 13% of the current taxi fleet of a major city by the three
electric vehicle models considered in the analysis could reduce CO2eq emissions
by about 6%. If the entire fleet was replaced in a 5 years period, CO2eq
emission could reach a reduction up to 82%.
