Further to the recent correspondence about Emission Zone stickers required in Germany, the easiest way to obtain one of these is to apply on-line at https://www.berlin.de/labo/kfz/dienstleistungen/feinstaubplakette.shop.en.php and they will send a green '4' sticker by return of post for just six Euros, payable by credit card online. All foreign cars registered later than 1996 qualify automatically for a green sticker, which is required for Berlin. Some other cities have less stringent requirements and may accept a yellow '3' sticker. The same emission zone sticker applies right across the country.

Umweltplackett stickers are also available before you go from from http://www.tuev-nord.de/en/traffic/Order_2897.htm for 12.5 Euros. That is the official site. Don't be tempted by the site www.umwelt-plakette.de - that will cost you 40 Euros. Stickers can be conveniently and legitimately bought via the internet from www.tolltickets.com, a German company for the Euro equivalent of about £7. PW tells us: emissions windscreen stickers required to transit some German cities can be obtained in advance for less than the cost of visiting a German TUV testing station, by going online to the Berlin regional administration office at: https://www.berlin.de/labo/kfz/dienstleistungen/feinstaubplakette.shop.en.php.

By providing a scanned copy of the V5 Vehicle registration Document and/or the Certificate of Conformity via this site, an emissions sticker will be sent to you (even to UK addresses) for the princely six Euros, postage included.
