Low environmental impact of alternatively supplied cars. Results of an investigation carried out in the North-East of Italy

The transport of both goods and passengers notably influences air quality. If strong decisions by the governments will not be taken, oil consumption for transport will be nearly doubled in 2030 if compared with 2000, thus considerably increasing the atmospheric presence of greenhouse gases. To boost the purchase of alternatively supplied cars would avoid serious, if not catastrophic, climatic changes. Our investigation shows what the situation is concerning new cars sold by SINA, an official concessionary firm of ten brands in the province of Pordenone, in the North East of Italy, covering about 40% of the local market. The supply types and the brands of the new cars sold in the branch offices of the firm from 2011 to August 2015 have been taken into consideration. The most sold cars are still petrol and diesel supplied, whereas alternatively supplied cars (liquefied oil gases, methane and electric) represent nowadays only 7.51% of the total in this territory. Processing of the data that have been put at our disposal by the firm allowed to compare the situation of the province of Pordenone with the Italian one, and to put in light the critical aspects still hindering the purchase of alternatively supplied cars.
