Abstract
In this paper, we carried out an analysis to estimate CO2 emissions discharged into the atmosphere by cars composing the car fleet that run on public roads in Romania. For this purpose, we have considered two types of cars, namely petrol engines, and diesel respectively. The calculation was performed for the total number of existing cars in Romania, in 2010, depending on the mileage and fuel consumption, having the total amount of CO2 discharged into the atmosphere by them as result. To reduce the amount of emissions was proposed as a solution, the electric car. It was calculated in this way, the amount of CO2 discharged into the environment in the process of electricity production required to power up this type of car. In the end, the CO2 emissions discharged both by cars fueled with petrol, diesel respectively and electric cars were compared.
