In the air quality directive (2008/EC/50), the EU has set two limit values for nitrogen dioxide (NO2) for the protection of human health: the NO2 hourly mean value may not exceed 200 micrograms per cubic metre (µg/m3) more than 18 times in a year and the NO2 annual mean value may not exceed 40 micrograms per cubic metre (µg/m3). These limit values come into force for concentrations measured from 1.1.2010 so during 2009 a margin of tolerance equal to an annual mean value of 42 micrograms per cubic metre (μg/m3) is still in place

Get in shape and be friendly to the environment all at once!
Journeys of less than 3 km may take less time if you walk, use a bike or even take the bus. If taking your kids along, try using a skateboard, skipping rope, rollerblades or buggy boards! Remember how much fun it was when you were a kid.
