Parsian Oil and Gas Petrochemical Holding is one of the major players in the country's petrochemical industry, which, with about 20 percent of Iran's production capacity and complexes such as Pardis and Zagros, has earned the title of the country's largest urea producer and one of the most important methanol producers in the Middle East.

Hossein Mirafazli, an energy expert, says: If only 10 percent of intracity trips are shared, about two million liters of gasoline will be saved daily, which is equivalent to more than $700 million in annual savings for the Iranian economy.

Petrofarhang Holding, the economic arm of the Farhangian Reserve Fund, has been able to consolidate its position as one of the main players in Iran's petrochemical industry in recent years, focusing on methanol production and developing petrochemical projects, and has emerged from losses with significant growth in production and profitability.
