Determine the correct CO2 class for your vehicle - with the DKV Mobility CO2 Class Check

DKV Mobility supports you in determining the CO2 class for your vehicle. The CO2 Class Check determines the correct CO2 class based on your vehicle data (you can find this in the certificate of conformity and the vehicle registration document) .

What happens after the CO2 check?

If the result is between CO2 class 2 and 5, please upload your certificate of conformity and your vehicle registration document in the corresponding upload area in the customer portal. DKV Mobility will check your data using the submitted documents and forward the result to the toll operator to ensure correct billing for your vehicle.
