Contact the Danish Emission Trading Registry outside normal business hours - only in critical cases

The Danish Emission Trading Registry has an emergency phone that account holders in critical cases can use outside of the normal business hours.

Critical cases are:

  • Suspending an account representative’s access to an account in the Danish Emission Trading Registry urgently.
  • A technical problem which prevents a transaction that is urgent. Be aware that transactions can only be carried out on weekdays between 10am and 4pm. Read more about transaction delays.
  • Suspecting that a transaction has been initiated on the basis of a criminal act. In this case, the account holder must also write an e-mail to co2register@erst.dk and immediately thereafter report the suspicion of fraud to the police.

Opening hours for the emergency phone

The emergency phone (+45) 3529 1862 is open Monday-Friday after normal business hours and until 9pm and on Saturday and Sunday from 10am to 6pm. On holidays you can call the emergency telephone between 10am and 6pm and on closing days (weekdays where the Danish Business Authority is closed) between 9.00am and 9pm.
