Information on emissions

The biggest problems with traffic now and in the future are traffic accidents and environmental hazards. The main and at the same time most commonly known negative effect of motoring on the environment and on human health is the pollution of the air. The biggest problem from the environmental point of view is considered the increasing carbon dioxide emissions that cause the so-called greenhouse effect, that is to say the gradual warming of the climate.

The carbon dioxide emissions of the traffic increase with the increase in traffic, as catalytic converters do not remove carbon dioxide. Acquiring a new car, on the other hand, will help in this matter as the fuel consumption of new cars decrease as technology develops.

The quality of the outside air affects many things

The impurities in the air affect human health, nature and materials. Many release sources, such as traffic, industry, energy production, heating of houses affect the quality of the air. A lot of pollution is also transferred across the borders from other countries. The impurities affect the quality of the air we breathe and cause many illnesses of the respiratory tract.

The quality of the air in the cities is mainly affected by different particles, nitrogen oxides, carbon monoxide, sulphur dioxide and hydrocarbons. Outside urban areas the air quality is affected by acid rain and high levels of ozone. The impurities in the outside air also affect the quality of the indoor air. Especially in the towns, large amounts of exhaust gases can enter the indoor air. Read more about the emissions on the web pages of the Pulmonary Association Heli: www.hengitysliitto.fi/english/

VTT Community Development has developed the LIISA calculation system that calculates the quantity of exhaust gas emissions in the municipalities, provinces and in the whole country. LIISA 1999 is today a part of the calculation system on the exhaust gas emissions from all of the traffic forms, LIPASTO 1999.
