Maximum sulphur limits for diesel fuel

The regulations set maximum limits for sulphur in diesel fuel for use on-road, off-road, in rail (locomotive), marine vessels, and stationary engines. The current maximum sulphur limits and effective dates for production, import and sales of diesel fuel in Canada are available in the compliance promotion information package for the federal fuels regulations. The goals of the regulations are to reduce air pollutant emissions and to ensure that the level of sulphur in diesel fuel used in Canada will not impede the effective operation of advanced emission control technologies installed on vehicles and engines.
