According to the CO2 regulation, vehicles must pay the CO2 tax if they have not been registered abroad for more than 6 months. Older passenger cars can be taken directly to the motor vehicle inspection for testing without processing.

Each time the CO2 tax is processed via the CO2 Exchange, a CO2 Assignment Form is required. This form makes it possible to assign the CO2 tax of a passenger car to CO2 Börse AG. Each vehicle can only be assigned once by the importer to another company after importation.

The federal government’s charge for the CO2 sanction will only be due after Swiss approval. For this reason, vehicles ceded to CO2 Börse AG must be registered in the same calendar year.


If a vehicle has been imported into Switzerland and is registered with the Road Traffic Office without a type certificate, a document dossier must be sent to the Federal Roads Office (FEDRO).


Companies from the car trade (small importers and large importers) can register free of charge on the CO2 Börse AG dealer platform. The vehicle is electronically registered on the platform and automatically generates a CO2 cession form. The form is delivered as an e-mail within a few seconds.

The following records must then be sent to FEDRO:

  1. Form 13.20 A (Swiss customs)
  2. COC (Certificate of Conformity)
  3. CO2 Assignment Form
  4. Foreign registration certificate, if applicable

Processing via FEDRO usually takes between 2 and 3 working days.


Private individualscan calculate the CO2 taxand then send the original documents for CO2 processing to the headquarters of CO2 Börse AG in Winterthur:

  1. 13.20 A (customs document)
  2. COC (Certificate of Conformity)
  3. Foreign registration certificate, if applicable

CO2 Börse AG then checks the documents and sends the dossier including the CO2 transfer form to FEDRO in Bern. After successful receipt of payment, the original documents will be returned to you. Processing usually takes 3 and 5 working days.
