If not the clean air, then the threatening fine should for sure be a good motivation for the drivers – the penalty for driving in the zone without the green, yellow or red sticker is €40 plus one “black” point into the directory of traffic offenders. The local authority plans to check the stickers during the regular traffic controls and does not want to hire any extra staff. In two years, clean air programme will reach its second phase when the vehicles with red stickers will not be allowed to enter the zone any more and the same will go for the yellow sticker owners in the third phase in 2012. From this year on only vehicles with green stickers will be allowed in the city. Although the strategy is often criticized by ADAC (General German Automobile Association) as disproportional and unnecessary, the city representatives believe it to be the only way to keep the city air breathable and stop the pollution. About 16.000 vehicles registered in Frankfurt do not meet the pollution criteria and will thus not be issued a sticker. People commuting to the city for work or school will also be affected by the law. Estimations suppose that there may be about 10.000 owners of unfitting vehicles among them. The certificate of exemption will only be given to the smallest workshops and businesses, that cannot afford to upgrade or innovate their vehicle fleet. There are still a few exceptions from the sticker rule, e.g. the firemen, police and ambulance, the vehicles of the physically disabled or the vintage cars. The Low-Emission Zones can already be found in 13 German cities - Munich, Augsburg, Oberhausen, Duisburg, Herne, Gelsenkirchen, Essen, Bottrop, Bochum, Mülheim/Ruhr, Recklinghausen und Wuppertal. A sticker bought in one of these cities is valid in any of them. The reason for these drastic measures is the EU Directive which states that the limit value of
50 Micrograms of fine dust in one cubic meter of air can only be exceeded on 35 days each year. The city council supposes the car access restriction to cause up to 11% reduction of the fine dust contents in the air. Frankfurt is the city with the worst air pollution in the German state Hessen. The fine dust limits have already been exceeded on 17 days in 2008 and the numbers from the previous years are not very comforting either – 33 days in 2007, 55 days in 2006 and 48 in 2005.
