Successful Conversion to Unleaded Gasoline in Thailand (World Bank Technical Papers)

The Government of Thailand within a five-year period (1991-95) introduced a series of initiatives that resulted in the elimination of leaded gasoline and reduction of ambient lead by a factor of 10. This report describes the strategies the government employed: educating about the dangers of airborne lead; setting a lower at-pump price for unleaded gasoline; helping the oil companies establish a system to distribute unleaded gasoline throughout the country; conducting monitoring and follow-up studies; and adjusting environmental regulations as necessary to support these policies.
