This guidance will help you access and navigate the Unit and Certificate Registry.
The registry allows you to manage, transfer and surrender your Safeguard Mechanism credit units (SMCs).
SMCs are the only units currently available in the registry. We will update this guidance as more features, units and certificates are added.
You will continue to manage Australian carbon credit units (ACCUs) in the current Australian National Registry of Emissions Units (ANREU) system until we transition them into the new registry. For information about ACCU transactions, read our ANREU account guidance.

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 Unit Surrender' form in Online Services. You should allow up to 5 business days for this form to be approved.
Once we have approved the form, a surrender obligation notification will be viewable in the nominated ANREU account:
