German Emissions Trading Authority

Virtual Post Office

We make comprehensive use of digital communication. Allocation applications, monitoring plans, emission reports and other documents have to be submitted to DEHSt via digital communication. For secure communication, DEHSt has established what is known as Virtual Post Office (VPS). All parties involved in emissions trading can carry out secure and legally binding digital communication.

All users must have their own mailbox at our Virtual Post Office (VPS). For information on how to install VPSMail on your local computer, please refer to the Virtual Post Office Installation Guide.

When you have successfully installed your mailbox, it must be activated by us after which it is then possible to send and receive messages. The following steps apply:

  • Send us a screenshot of your business card in an email to
  • We will then activate your mailbox.
  • You will receive an email confirmation from our customer service.
  • Mailboxes created with the ID card’s eID function will be activated automatically.

Please note: We recommend securing your local mailbox locally.
