The
environmental zone was introduced in many German cities to protect air quality.
Munich introduced the environmental zone on 1st October 2008. To be
allowed to drive in the low emission zone, the vehicle must display an
environmental badge. Over the years, the rules have been tightened to determine
which sticker or badge is required to enter the zone. Since 2012 only vehicles
with a green sticker can enter the low emission zone. Excluded from this are
for example ambulances, vehicles belonging to doctors and diplomats and
vehicles with special permits. A vehicle without an environmental sticker can
be fined 80 euros in the low emission zone.
