Abstract

The role of road transport emissions in air pollution phenomena is considered to be very important, not only as far as photochemical smog is concerned, but also for acidification. This has been demonstrated by the results obtained with two regional scale models. The emission scenarios used for this impact study have been based on the possible abatement strategies currently under discussion in Europe and include also recent European legislative actions (EU directives, Auto Oil Programme). The emission factors used in the scenarios are partially derived from on-the-road traffic emission measurements carried out for gasoline passenger cars with a closed-loop controlled three-way-catalyst (TWC) and for a carburetted non-catalyst car. The results of the scenario computations show that
