What is the Guarantee of Origin?

The Guarantee of Origin (GO) is an internationally aligned assurance scheme being designed to track and verify emissions associated with hydrogen and renewable electricity made in Australia.

Over time, it could expand to include a range of products such as metals, low emissions ​fuels and other products made in Australia.

GO will show where a product has come from, how it was made, and the emissions throughout its lifecycle.

This will help decarbonise the Australian economy by encouraging sellers to reduce carbon intensity. Increasing transparency for consumers will give participating sellers a competitive advantage in the Australian and international market.

We're designing the GO scheme in partnership with the Department of Climate Change, Energy, the Environment and Water.

Renewable Electricity Guarantee of Origin

The proposed REGO would allow participants to create renewable energy certificates for all types of renewable energy generation.

Designing the Guarantee of Origin

We ran workshops and held meetings in partnership with the Department of Climate Change, Energy, the Environment and Water to develop the GO Scheme.

How it works

GO is a voluntary scheme for producers in certain industries to verify the carbon intensity of their products.

Product GO scheme

When an eligible product like hydrogen is produced, a digital certificate will be issued that travels through the supply chain until it is sold and the certificate consumed. This will show:

  • where it was made
  • what it was made from
  • how it was transported.

At each stage, details of greenhouse gas emissions and other information are added to the certificate.

We will validate these details to ensure the integrity of each certificate.

Renewable Electricity GO (REGO) scheme

The proposed Renewable Energy Guarantee of Origin (REGO) certificate mechanism would build on the large-scale generation certificate (LGC) framework which ends in 2030.

The REGO certificate mechanism would provide certainty for renewable electricity investment and procurement, and support Australia’s energy transformation.

Who can participate

Once legislation is developed, the product GO scheme will initially be open to the hydrogen industry and its derivatives. The REGO scheme will be open to those in the renewable electricity sector.

The scheme is expected to expand to include new industries over time.

Guarantee of Origin Emissions Accounting Approach calculator

An excel spreadsheet that enables users to populate their own data to generate an estimated emissions intensity of hydrogen based on the proposed emissions accounting approach.

Go to the calculator on the department's website.

Designing GO

Our co-design process with the department has included hydrogen and ammonia producers and stakeholders.

The department and CER continue to consult with a broad range of stakeholders.

Learn more about the GO consultation process on our consultations page, or the department's consultation hub.

Our role

We are codesigning the GO scheme with the department and our stakeholders.

Once legislated, we will administer the GO scheme. This will include:

  • participant enrolment
  • GO certificate creation and transfer
  • compliance activities.
