How Long Remains the Environmental Badge Valid and how should it be Settled on the Vehicle?

As long as the motor of the vehicle does not get changed and as long as the environmental badge does not get damaged, it remains valid for the entire lifetime of the vehicle.
For the settling of the environmental badge on the vehicle, please note the following information: the badge must be stuck from the inside in the lower or upper right corner on the windscreen. Do not stick it in the green tinted area of your windscreen, otherwise will it harm the visibility of the badge.
It is also important to notice that the IG-Luft environmental badge authorization form must be constantly on-board. This document is delivered with the environmental badge and helps in case of controls to prove the authenticity of your environmental badge.
