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

Eat meat in moderation!
If you're a meat eater, consider reducing your meat consumption and going for quality rather than quantity. Production of meat consumes enormous amounts of energy, not only for the growth and transport of animal feed, but also for the heating, air conditioning, and lighting of the immense animal farms. Changing to a diet with less meat helps the environment, but is also good for your health. It is best to buy meat from local producers and buy organic too.
