Exemption from particle filter requirements

An exemption from the particle filter requirements in low emission zones may be granted, provided that certain exceptional circumstances apply. Exemptions are only granted for limited periods.

In special cases, your vehicle can be granted temporary exemption from the Danish low emission zone regulations. Few visits are not reason for exemption.

Requirements for exemption

Exemption may be granted, if:

  • the installation of a particle filter will pose a safety risk, e.g. where the installation could cause considerable damage to the engine and/or possibly result in fire,
  • your vehicle is a unique special-purpose vehicle, which is only used few times every year in the low emission zones and the installation of a particle filter involves a cost that lies significantly above the average price level (approx. DKK 50,000) or
  • it is technically impossible to install a particle filter or make it work properly, due to special fitting or use of vehicle.


Exemption must be granted, if:

  • it is documented that the applicant is unreasonable, harshly affected financially by the particle filter requirement and therefore cannot afford to install filters. Documentation, in the form of the company's accounts for the past five years, must be presented.
