The classification of cars depends on the emission of exhaust fumes of carbon monoxide, carbon hydrogen, nitrogen monoxids and particles .The sales of environmentally classified cars has increased from 11% in 1992 to 60% in 1996.

The environment classification system has been introduced to reduce the negative effect of automobiles on the environment.This is a way to encourage lower exhaust pollution long before it becomes obligatory.

Class 1 & 2 cars have lower emission then class 3 cars.Class 3 cars must be under the legal level of emission. Cars with a higher emission canīt be sold. Environmental classifications will change in time.The voluntary demand for classes 1 & 2 creates pressure to reduce the legal level of class 3.
