Baku, Azerbaijan, June 30
By Fatih Karimov - Trend: Distributing gasoline with higher octane in the Iranian capital, Tehran, has lowered air pollution in the city.
Managing director of National Iranian Oil Refining and Distribution Company, Abbas Kazemi, said distributing 91-octane gasoline instead of 87-octane gasoline has helped improve the performance of cars, Iran's IRNA news agency reported on June 30.
Supplying imported premium gasoline in recent months to gas stations in Tehran has led to a decline in air pollution, he added.
Kazemi said on April 13 that Iran plans to daily import 10 million liters of gasoline to compensate for stopping production of gasoline in petrochemical complexes.
"The Iranian government has ordered the petrochemical complexes to stop producing gasoline," he said, adding that the country's gasoline imports were around 3.5 million liters per day in the previous calendar year, which ended on March 20.
Speaking of pollution, Iran's Tehran is considered to be among the most polluted cities in the world. Last year, according to PSI (Pollutant Standards Index), Iran had 147 days during which air quality was substandard. Two years ago, this number stood at 217 days.
