Closing the gasoline system – control of gasoline emissions from the distribution system and vehicles

Apr 13, 1990

Report no. 3/90: This report shows that a series of measures effectively closing up the gasoline system of distribution and use in motor vehicles is the preferred strategy to control gasoline emissions. These emissions contribute about 40% to the volatile organic...

Nov 13, 1989

Report no. 10/89: This study examines the consequences to refineries of making step-wise reductions in the sulphur content of diesel fuel from 0.26 to 0.05% wt. The EC-12’s 95 refineries have been grouped into four categories for the purposes of representing...

Economic consequences of limiting benzene/aromatics in gasoline

Jul 21, 1989

This report records the economic consequences to four different types of refineries in Europe if the benzene content of gasoline is required to be limited to 3% v01 or 1% vol. The consequences of also setting limits on aromatics content are also investigated. The...
