Legal Framework of the Austrian Environmental Badge

The origin of the environmental zones in Austria is based on the IG-L emissions protection law for the air BGBl. I Nr. 115/1997 dated 30.09.1997, which regulates generally the protection of the environment and the fight against pollution. The § 14 refers especially on road vehicles (here a ling to PDF 1997_115).

Based on this, a recast IG-L emissions protection law for the air has been enforced in 2013, which strengthen some of the dispositions of the former law (here a link to the PDF document).
The Austrian environmental badge has been introduced on 06.04.2012 in the regulation for the classification of exhaust gases, which came into force on 01.09.2012 as BGBLA_2012_II . Am 31.10.2014 kam dann noch mit der 272. Verordnung des BGBLA einige wichtige Ergänzungen hinzu. (pdf-Datei 272)

Simultaneous, a legislative decree came into force, including detailed requirements about the environmental badge. The decree settles, among other things, the appearance, the composition of the badge, its settling on the vehicle and its assignment to the different emissions standards in the regulation for the classification of exhaust gases.

Prior to the legislative decree on emissions classification, a few circulation interdictions occurred in some parts of the low emission zones.  
Time and spatial restrictions had been already settled for Lorries.
