What are REGO-backed tariffs, and how can companies obtain evidence that REGOs have been retired on their behalf?

A REGO-backed tariff means your electricity supplier claims your energy use is matched with renewable electricity, and they use Renewable Energy Guarantees of Origin (REGOs) to prove it.

To ensure this claim is credible, the supplier must:

Retire REGOs in your name or on your behalf
Provide evidence of REGOs, including volume, generation period, and retirement date

You can request this proof directly from your supplier. It usually comes as a certificate or declaration confirming that the REGOs match your actual electricity usage over a defined period (typically a calendar year).

If the supplier cannot or will not provide this evidence, then you may not be able to claim renewable electricity use in your Scope 2 market-based reporting. In that case, you can buy REGOs separately through a trusted provider like ACT to ensure you have the proper documentation.
