Guarantee of Origin Scheme, PGO and REGO certificates

The Guarantee of Origin Scheme is a national certification framework administered by the Clean Energy Regulator that tracks the emissions intensity and origin of products such as hydrogen and renewable electricity.[10] It issues Product Guarantee of Origin certificates for low‑emissions products and Renewable Electricity Guarantee of Origin certificates for renewable electricity generation, providing a standardised way for producers and consumers to evidence how and where energy products were made and their associated lifecycle emissions. The scheme underpins eligibility for the Hydrogen Production Tax Incentive by verifying both the emissions intensity of hydrogen and compliance with grid-matching rules for grid-sourced electricity.[7][10]
