Indonesia will expand the use of high-octane fuel during the upcoming Asian Games (Asiad), to address the air quality issues in cities hosting the sports event. The official order was issued by Indonesia’s Environment and Forestry Ministry, after it sent an official notification letter to the president requiring this type of fuel to be used for public transportation vehicles, during the event, according to PT Pertamina Spokesperson Adiatma Sarjito. Pertamina is Indonesia’s state-owned oil and gas company.

The order would apply to three cities, Bandung, Jakarta and Palembang, from August 18 to September 2.

“The international requirement to host the sports event is that sulfur particles in the air must be no higher than 25 micrograms per meter square,” Adiatma said.

To address the order, Pertamina will prioritize the distribution of this higher octane gasoline.

Due to the limited storage tanks in service stations in these cities, Adiatman said that the move would consequently reduce the distribution of other types of fuel. Pertamax Turbo, which is a Euro 4-compliant fuel, is the only type of fuel that complies with the ministry’s order.

The ministry’s order will also apply during the International Monetary Fund-World Bank annual meeting slated for October this year in Bali.
