This guidance will help you access and navigate the Unit and Certificate Registry.

The registry allows you to manage, transfer and surrender your:

  • Australian carbon credit units (ACCUs)
  • Safeguard Mechanism credit units (SMCs).

We’ve also created a short YouTube video about the registry. This will help you learn how to:

  • access the registry
  • use key functions
  • confidently complete transactions to manage your ACCU and SMC holdings.

ACCUs are live in the Unit and Certificate Registry

The migration of ACCUs from the ANREU system to the Unit and Certificate Registry is now complete. Log in to your ANREU account via Online Services to view and manage your ACCUs in the registry.

The registry is foundational infrastructure that will support the ongoing growth of deep, liquid and transparent carbon markets.

To access ACCU and SMC holdings in the registry, you need an ANREU account. If you don’t have an existing account, find out how to open an ANREU account.

Only authorised representatives of an ANREU account can access the account and make transactions on behalf of the account holder.

Surrender units for safeguard obligations

Before an SMC or ACCU surrender can be actioned in an ANREU account, the responsible emitter for the safeguard facility must first submit a 'Safeguard Carbon Units Surrender Request' form in Online Services. You should allow up to 5 business days for this form to be approved.

Once we have approved the request form, a safeguard surrender obligation task will be viewable in the nominated ANREU account in the registry.

  1. Go to your ANREU account in the registry.

Confirm the details are correct before clicking ‘Begin surrender’.
