The Danish Parliament passed new legislation regarding low emission zones in Denmark in June 2020. The new legislation assigned the main responsibility for enforcing low emission zone regulations to the Danish Environmental Protection Agency with effect from 1 July 2020. At the same time, automatic digital control has been introduced in the low emission zones. The control procedure are based on ANPR (Automatic Number Plate Recognition) cameras using number plate recognition technology. The same technology is used at the Storebælt Bridge and at parking facilities.

Automatic Number Plate Recognition
A number of control points have been set up in the four low emission zones. The automatic number plate recognition technology control that vehicles in low emission zones comply with the requirements. This is done by comparing number plate information with the data contained in vehicle registers in Denmark and abroad. 

If a vehicle not permitted to drive in a low emission zone is spotted at a control point, the Danish Environmental Protection Agency will issue a penalty charge notice. Danish vehicle owners will receive the penalty charge notice via their E-boks while foreign vehicle owners will be contacted by post. Under the new legislation, Sund & Bælt collects the vehicle data for the purpose of deciding whether a penalty charge notice should be issued.

CCTV in operation signs are located at the control points.

Mobile control units
Checks on vehicles in low emission zones are also carried out by ANPR-equipped vehicles.

Low emission zones are marked with the following signs:
