Car limit values for pollutant emissions: Table
In order to reduce exhaust gas pollutants, the limits for car emissions are set by the EU and regulated by uniform directives and regulations throughout Europe.
The following tables show excerpts from the development of the standards for petrol and diesel vehicles.
