In March 2022, the Danish Parliament decided that the five low emission zone municipalities could extend the particle filter requirement to apply to diesel passenger cars as well. The new stricter low emission zone requirements were adopted by the five municipalities and came into force on 1st October 2023.
Since 1st July 2020, stricter low emission zone requirements have applied to vans, lorries and buses in Denmark.
The Danish Environmental Protection Agency is responsible for enforcing the low emission zones.
The control of the low emission zones is based on the automatic reading of license plates with cameras and are crosschecked with available data from the respective country's vehicle register. Sund & Bælt collects vehicle data on behalf of the Danish Environmental Protection Agency for use in control and enforcement of the low emission zone requirements. The police also controls and enforces the low emission zones.
