The committee adopted a report by Mr Noël MAMERE (Greenns, F) on the quality of petrol and diesel fuels, amending Council Directive 93/12/EEC. Calling for minimum environmental fuel specifications for petrol and diesel, the report said that Member States needed the right of differential taxation in order to promote the adoption of more advanced fuels. Low-quality diesel should no longer be sold after 1 January 2005. Special specifications were needed for the fuels (diesel, LPG and NGV) of fleets of buses, taxis and commercial vehicles, which are particularly responsible for urban pollution. �
