Summary

The aims of the European Auto-Oil II Programme were to make an assessment of the future trends in emissions and air quality and establish a consistent framework within which different policy options to reduce emissions could be assessed using the principles of cost-effectiveness, sound science and transparency. The scope of AOPII included all the main conventional pollutants: SOx, CO, NOx, Bz, O3 and PM.

The results of the modelling of air quality in 2010 suggested that of the targeted pollutants, neither CO nor Bz would pose challenges in any of the modelled 10 cities. Exceedences of the objective for NO2 were predicted only for two cities. Exceedences of the PM10 objective would be more widespread, affecting possibly half of the cities.

A detailed assessment was made of the full range of potential road transport measures, including "non-technical" measures, comparison with other sources than road transport; and an evaluation of the benefits of reducing emissions.

The programme ran from spring 1997 to year 2000 and is reported in a series of working group and consultants reports and in an overview report from the services of the European Commission. Reports and further detail is available from the Commission’s Auto Oil II web site.

Auto Oil II Fuels technology Working Group (WG3)

Regarding automotive fuels, input scenarios were developed for complementing 2005 gasoline and diesel specifications by assessing the effects of incremental changes, based on EPEFE equations, and estimating their costs using a European linear programming model on oil refining. The study concluded that gasoline parameter changes show trade-offs between pollutants; changing diesel specification could provide reductions in particle emissions, especially in passenger cars and light duty vehicles; introduction of alternative fuels could potentially provide effective solutions to improve air quality, particularly at the local level and city fuel scenarios are also relevant in view of their potential for reducing PM emissions.

Sulphur was not among the parameters studied in the Auto Oil II programme. Regarding sulphur the European Commission has launched a Review of Sulphur in Petrol and Diesel.
