Abstract The alternative fuels (as bio-fuel, natural gas, hydrogen) have been integrated in the European policy for transports and energy because they constitute one of the few available alternative choices in which the petrol and the oil for engines can be replaced as fuels for the transports. In the present study, we have been calculated the levels of air pollution in the city of Heraklion and how these levels are influenced by the use of bio-fuels. For this, data of the main transport vehicles in Crete: type, use and seat of vehicle, the usage characteristics and energy consumption, such as covered kilometers, nominal or real consumption of fuel, weight, usage percentage in the city or highways etc, have been employed. Based on these elements the gas emissions in the city of Heraklion from the traffic were calculated and how these are changing with the use of bio-fuels and specifically the gas emissions VOCs, NOx, CO2, CO (based on the specifications of the manufactures of each vehicle). Then, by the mean of chemical model of -0- dimensions the levels of pollution in the city of Heraklion were calculated and how they are influenced by the circulation of vehicles of each type with the use of conventional fuels as well as the way that levels change with the use of bio-fuels. The present work was aiming the estimate of the effect of use of bio-fuels and specifically biodiesel with contents 20%v/v (B20) and 100%v/v (B100) improvement of quality of the air. The ideal case of full absence of traffic was also studied. We have shown that the use of bio-fuels and mainly the B100 leads to lower levels of ozone than the conventional fuels of cars.
