How much are cars polluting

Emissions of pollutants such as nitrogen oxides, hydrocarbons, carbon monoxide, dust, causes or exacerbates a number of health problems. The impact over health because of traffic has consequences: higher incidence of cancer and heart disease, respiratory problems and their severity. Technological improvements that have reduced emissions have been offset by an increase in traffic, so that emissions are still rising.

Vehicles, especially cars, are the main source of air pollution in urban areas in Europe. The transport sector is responsible for 63% of NOx emissions, 47% of emissions of volatile organic compounds such as benzene, 10-25% of powders and 6.5% of SO2 emissions in rural areas - values are higher in urban areas. Pregnant women and children, youth, elderly and those with respiratory problems are under the greatest health risks.

In EU, about 28% emissions of greenhouse gases are from transport, 84% of these emissions from road transport. More than 10% of carbon dioxide emissions in the EU come from road traffic in urban areas.

Noise pollution
About 65% of EU population is exposed to unacceptable high levels of noise.The most part produced by urban traffic. Although noise affects individuals in different ways, it's causing both: discomfort and health problems. Physical and psychological effects include a higher heart rate (and therefore higher risk of cardio-vascular diseases), mental disorders and higher levels of stress, sleep disorders, cognitive problems, of understanding and focus for children and very high noise levels, hearing problems.

Technological development led in the last decades to reducing of 85% the level of noise generated by vehicles, but the problem persists due the vehicles and traffic number increasing.
