Sulphur in gasoline regulations

These regulations limit the sulphur content of gasoline to 12 mg/kg on January 1, 2020. Alternatively, gasoline producers and importers can elect to apply a pool average sulphur limit, in which case the pool average limit becomes 10 mg/kg, with a never-to-be-exceeded batch limit of 80 mg/kg.

A primary supplier who is complying on a pool average basis may also participate in a temporary sulphur compliance unit (SCU) trading system, which will be in place until the end of the 2025 compliance year.
