The new Unit and Certificate Registry

The Unit and Certificate Registry is a modern, easy-to-use system that will allow account holders to manage and trade the units and certificates we administer. This will facilitate greater investor access and trading in carbon and environmental markets.        

The registry will make it easier for account holders to: 

• view and trade units and certificates
• meet their regulatory obligations
• engage in voluntary emissions reduction by consolidating multiple unit and certificate types in a single location. 

Transition to the new registry

We’re transitioning from the current ANREU system to the Unit and Certificate Registry. If you already have an ANREU account in the current ANREU system, your account will automatically be mirrored in the new registry. If you open an ANREU account, it will be created in the current ANREU system and the Unit and Certificate Registry.

The first unit type available in the registry will be Safeguard Mechanism credit units (SMCs) in early 2025. Australian carbon credit units (ACCUs) will follow later in the year. ACCUs will continue to be managed in the existing ANREU system until we transfer them to the new registry.

Other units and certificates will be progressively added to the registry over 2025, including:

• Renewable Energy Guarantee of Origin certificates (REGOs)
• biodiversity certificates (for the new Nature Repair Market).

Large-scale generation certificates and small-scale technology certificates will remain in the REC Registry.

Benefits

The registry will provide a modern, secure, single place to hold and transfer multiple unit and certificate types.  

It will improve the:

• user experience for the management and transfer of holdings
• accessibility and visibility of unit and certificate attribute data
• account creation and management experience 
• ability of users to download, share and manage their registry data
• integration of the registry with our other online systems, giving users a more seamless user experience.

The registry will also have the capability to integrate with external digital trading platforms, including the potential for exchange-trading of units and certificates.
