"TEHRAN -- Iran's ambitious plan to flood the market with synthetic petrol has been marred by ecological concerns. Tehran says it is becoming self-sufficient in petrol, in the hope of warding off the pain of further economic sanctions. But the effort has many detractors inside Iran, who say the method chosen - making petrol out of chemicals rather than crude oil - is uneconomic and environmentally unfriendly.
For the last five months, Iranian government officials have been saying the country is no longer reliant on petrol imports thanks to a development program launched two years ago to increase production and thereby cushion the country against a possible international ban on fuel sales."
