Important security guidelines

Please observe the following security guidelines when accessing and using the Swiss Emissions Trading Registry (EHR):

  • To access the EHR, please use only this URL:
    Note: A secure connection to the EHR is established in the background.
  • Use a specific password to access the EHR. Do not save the user name or password in the browser and close your EHR access after you have finished your activities.
  • The user name and password you use to access the EHR are personal and should not be disclosed in writing or verbally to third parties or registry administrators. Please ignore any requests to disclose this information and notify the EHR help desk if someone requests it from you.
  • As a user, you are solely responsible for updating your operating system, antivirus software, programs and firewalls to protect yourself against viruses, Trojan horses and other problems.
  • Never click on links or attachments in e-mails from unknown senders or with content that appears untrustworthy.
  • Do not use a USB key of unknown or uncertain origin.
  • Never allow different users to use the same computer to log in to the Swiss EHR. This lowers the risk of criminals being able to access and misuse the login information of several users by contaminating a computer with malware.
  • If you suspect that a third party knows your login information, immediately block access to your account. To do so, enter your correct user name and an incorrect password three times in the EHR login screen. Then call the EHR help desk.
  • All e-mails sent by the EHR and the EHR help desk are digitally signed. The sender is clearly identifiable as The official key of the digital signature is published at
    If you receive an e-mail from the EHR or the EHR help desk without this digital signature or with a different digital signature, contact the EHR help desk directly.
  • Never log in to the EHR from your mobile telephone. If your device is infected with malware, criminals would have access to all your login data.

In all cases of doubt, notify the EHR help desk immediately.
