The G-Kat sticker or ozone sticker was introduced in July 1995 as part of the Ozone Act. Vehicles with a regulated catalytic converter are affixed to the windshield with a sticker indicating the license plate number . The limit value for the ozone concentration was 240 μg / m³. Both the law and the sticker turned out to be superfluous because only once in Hessen was a driving ban due to summer smog due to ozone alarms . The regulations were also replaced by the “ environmental badges ” in 2007/2008 . The G-Kat sticker has become meaningless and can be removed since then.

The self-adhesive sticker was attached to the inside of the windshield . The handwritten entry of the license plate was made directly on the adhesive layer.
