Disclosure Type: Green tariff

Verification basis: Green tariff

This disclosure type refers to conventional energy supply agreement between an organisation and an energy supplier. These can be either project specific (i.e. the energy supplier delivers energy from one/more specific projects they operate), or retail. 

What disclosures are required for verification?

To make a verification claim based on green tariffs, a provider must share one or more of the following:

• Disclosures of the green tariff, including:
  • The timeframe for energy supply
  • The type of energy being supplied
  • The quantity of energy being supplied
• Disclosures from the energy supplier showing the fuel-mix of the energy delivered.

Third-party limited assurance

For providers unable to share disclosures in the aforementioned categories, we also accept third-party limited assurance report covering Scope 1 and Scope 2 GHG (greenhouse gas) emissions for that organisation. This means that an independent auditor has obtained sufficient and appropriate disclosures that the organisation has used one/more of the mechanisms listed above to support claims of using 100% fossil-free energy from their hosting infrastructure.

To make a verification claim based on limited assurance, the limited assurance must specify:

• The region/s it is applicable to
• The GHG Scope/s (Scope 1 or 2) which is being assessed
• The basis under which the limited assurance has been reached. Namely, use of:
  • Self generation
  • Direct procurement
  • Green tariffs
  • Unbundled certificates
  • Passive procurement 

Providers must also share the related sustainability report and/or other documents for which that limited assurance has been provided.
