I was talking to a German guy i'm working with yesterday about our trip to Irmscher and he told me about this. I think we will need to get one of these sticker's as Stuttgart is in the list.
I got this information from the AA website.
Low Emissions Zones
From 1st January 2008, restrictions on the circulation of vehicles will be introduced in several German cities, in order to reduce the levels of emission of fine particulates in some areas. The areas where restrictions apply will be indicated by signs showing coloured vignettes ("Plakette") - green, yellow or red. To enter these areas, drivers will have to stick a vignette on their vehicle windscreen, this can be obtained from technical inspection centres or approved garages, fine for non-compliance €40.00. The owner of the vehicle (German or foreign) is required to present the registration certificate of the vehicle and pay a fee of 5 to 10 Euros. The colour of the vignette issued will depend on the type of engine and the Euro classification of the vehicle.
Owners of foreign-registered vehicles can obtain a sticker by sending an email to the Berlin vehicle registration authority at email@example.com attaching a copy of the vehicle registration certificate specifying the emission code or a manufacturer’s certificate (preferably pdf files). Upon verification of the documents, the registration authority will send a payment request by advance email including the bank details to the applicant. A €6 administration/handling fee will be charged per sticker. The sticker will be sent to the applicant by direct mail. As order processing may take two to
three weeks, stickers should be ordered well in advance. Alternatively you can now obtain a sticker from the Cologne vehicle registration office by sending an application including a copy of the vehicle documents and €5 (cash or crossed cheque) to Kfz-Zulassungsstelle, Max-Glomsda-Straße 4, D-51105 Köln.
