We have only one earth

In Europe, emissions of many pollutants have decreased significantly since 1990, so that the air quality has improved over the region. However, since 1997, concentrations of particulate matter and ozone in the atmosphere have not improved significantly despite lower emissions. A significant proportion of Europe’s urban population still lives in cities, where limits on air quality (set for the protection of human health) are exceeded. A number of countries are also likely to miss one or more legally binding emission ceilings for 2010 for four major air pollutants. The need to reduce exposure to air pollution remains an important point.
