CO2 emission class

What is a CO2 emission class?

A CO2 emission class reflects the extent to which your truck impacts the climate.

It refers to your truck's energy consumption, excluding the CO2 emission from producing diesel, gas, electricity, or hydrogen, that powers the truck.

Five CO2 emission classes

It is a requirement from the EU that trucks are categorized into one of five CO2 emission classes. This is stipulated in an EU directive from 2022.

Your truck's CO2 emission class is determined based on the truck's specific CO2 emissions and a predetermined CO2 reference value for your vehicle subgroup.

CO2 emission class

Description

1

Truck with date of first registration before 1 January 2019 and which does not comply with the other CO2 emission classes

2

Truck emitting 5% less than the CO2 reference value

3

Truck emitting 8% less than the CO2 reference value

4

Low emission truck emitting 50% less than the CO2 reference value

5

Zero emission truck determined by the vehicle's power source, e.g. electricity or hydrogen

Where can I see the CO2 emission class for my truck?

If your truck is registered in Denmark, you will be able to see the truck's CO2 emission class in the Danish Motor Register (DMR) during the course of 2024.

If your truck is registered abroad, you must provide information about your CO2 emission class when purchasing a Kilometer Toll Ticket. If you pay road toll through a provider, the EETS provider can guide you on how to obtain the CO2 emission class for your truck. The CO2 emission class is based on information about your truck in the registration certificate and the customer information file.

The tool is not affiliated with Sund & Bælt Holding A/S, and your usage will be at your own risk.

How does my truck's CO2 emission class get registered in the Danish Motor Register?

New trucks are registered with a CO2 emission class based on information from importers and vehicle inspection stations.

If your truck was registered before 1 January 2019, it will automatically be placed in CO2 emission class 1.

If your Danish truck was registered after 1 January 2019, the Danish Motor Vehicle Agency and the Danish Road Traffic Authority collaborate with DBI IT to register the relevant information in the Danish Motor Register to determine the CO2 emission class.

For a small number of trucks, the information is not available, and the owners will receive a letter requesting them to submit the relevant information to determine the CO2 emission class.

Can my truck's CO2 emission class change?

Your truck's placement in a CO2 emission class is reassessed every six years from the date of the first registration of the truck.

Check the Danish Motor Registry under the field 'Date for reclassification' for further information on when your truck's emission class will be reassessed.

How is the CO2 emission class calculated?

The calculation is based on information about your truck in the registration certificate and the customer information file. More specifically, these data are used:

  • Fuel source.
  • The first registration.
  • The vehicle's specific CO2 emission.
  • Vehicle group and subcategory (if the subcategory is not listed in the customer information file, the subcategory is determined based on vehicle group, cab type, and the engine's nominal power).
  • Cab type.
  • The engine's nominal power.

Example of a truck in CO2 emission class 3

  • 3-axle truck (6x2) - use: traction for semi-trailer.
  • Fuel source: Diesel (combustion engine).
  • Date of the first registration: December 2023.
  • Vehicle subgroup: 10-LH.
  • The vehicle's specific CO2 emission: 48.1 grams per ton kilometer.
  • Vehicle group: 10.
  • Cab type: Sleeper cab.
  • The engine's nominal power: 368 kW.

Do you believe your truck is not registered correctly?

Please contact the Danish Motor Vehicle Agency with the relevant documentation if information on your truck needs to be amended in the Danish Motor Registry.
