Iran: Air Pollution Abatement Programme

Tehran Municipality will convert 1,500 diesel-fuelled buses to Compressed Natural Gas (CNG). A mandatory emission inspection and control program was set up for motor vehicles permitted to enter the city’s Restricted Traffic Zone (RTZ). Lanes were specifically designated for buses. As a result, urban bus services, including ridership have increased in the last three years by thirty-five percent and average trip time has decreased. A Park and Ride facility with a capacity of 200 cars has also increased bus ridership.

Date Implemented: 1998

Status: In Force; Mandatory
