Seventy percent of the air pollution in the city of Tehran stems from mobile sources, and in comparison with other major cities of the world, Iran`s capital experiences one of the most polluted metropolitan areas. There exists a surplus of liquid petroleum gas (LPG) in the Persian Gulf and Iranian market, in addition, Iran possesses the second largest reservoir of natural gas in the world. These alternative energy resources create a favorable potential fuel for city of Tehran. Experiments carried out in Tehran indicate that in converting the taxis from gasoline to a dual fuel (LPG/gasoline) car or to a dual fuel natural gas vehicle (NGV) reduce all major pollutants (CO, HC, NOX, Pb) substantially. Following the author`s recommendation, the number of LPG dispensing units in gas stations are increasing and the number of dual fuel taxis amount to several thousands in the metropolitan area. The conversion of diesel buses in the Tehran Public Transportation Corporation to natural gas (NGV) has been recommended by the author and vast experimental works are underway at the present time.
