German Environmental Zones (E-zones)

Following amendments to Road Traffic Licensing regulations in June 2007, many German cities are now creating E-zones. These E-Zones are designed to improve air quality and meet EU targets for particulate matter.

The first E-Zones started in January 2008, there will be 40 by the end of 2010. Vehicles are permitted or excluded on the basis of windscreen stickers which are required to show the vehicle's emissions class.

German E-zones Stickers

Older vehicles of Euro 1 or earlier are not eligible for a sticker.

Defined according to 35th amendment to the Federal Emission Control Act 35. BImSchV.

Initially the E-Zones' rules ban vehicles without a sticker (except vintage vehicles). By retrofitting an approved diesel particle filter, these vehicles can improve their emissions performance to make them eligible for a red or yellow sticker.

The Eminox CRT® (Continuously Regenerating Trap) particulate filter is a closed filter which virtually eliminates particulate matter, hydrocarbons and carbon monoxide. It has been tested and approved in accordance with the official retrofit filter approval method (as defined in Appendix 27) and is ideal for heavy duty vehicles such as buses and trucks.

Many cities will only allow vehicles with green stickers. Again retrofit improvements will be allowed, fitting an Eminox CRT® could upgrade these vehicles making them eligible for green stickers.

The CRT® has been used as part of air quality improvement schemes in cities across Europe, including 8000 buses in London and 3000 buses in Paris. This proven technology reduces particulate matter by more than 90% and therefore will not encounter the problems experienced with some car filters. Eminox filters are ABE Approved in accordance with Appendix 27 by KBA after tests carried out with TÜV.

From January 2009 vehicles fitted with an Eminox filter can save up to 8.4cents/km on MAUT tax, giving an average saving of €12,600 per year (based on 150,000km per year).
