Guarantee of Origin (GO)
- March 17, 2026
- Northmore Gordon
A Guarantee of Origin (GO) is a European energy certificate that verifies electricity has been generated from a specific renewable source. GOs are used to track and substantiate renewable electricity claims and are the European equivalent of Renewable Energy Certificates (RECs). They can be traded independently of electricity and are widely used by RE100 companies to meet renewable energy targets.

What is a Guarantee of Origin (GO)?
A Guarantee of Origin (GO) is a European energy certificate that verifies electricity has been generated from a specific renewable source. GOs are used to track and substantiate renewable electricity claims.
How does a Guarantee of Origin (GO) relate to Renewable Energy Certificates (RECs)?
A Guarantee of Origin (GO) is the European equivalent of Renewable Energy Certificates (RECs), serving the same function of tracking and substantiating renewable electricity claims.
Can Guarantees of Origin be traded separately from the underlying electricity?
Yes, according to Northmore Gordon's glossary, Guarantees of Origin (GOs) can be traded independently of the electricity they represent.
Who uses Guarantees of Origin to meet renewable energy targets?
Guarantees of Origin (GOs) are widely used by RE100 companies to meet their renewable energy targets.
Is a Guarantee of Origin (GO) the same as a Renewable Electricity Guarantee of Origin (REGO)?
The page defines GO as a European renewable electricity certificate; the related REGO (Renewable Electricity Guarantee of Origin) scheme, per knowledge-base context, is an Australian certificate scheme administered by the Clean Energy Regulator that similarly records renewable electricity attributes, though it operates separately from Australia's Renewable Energy Target.
Can a facility create both a REGO and a Large-scale Generation Certificate (LGC) for the same electricity generation?
No. Per the knowledge-base context, a facility cannot create both REGOs and Large-scale Generation Certificates (LGCs) for the same electricity generation, and this restriction also applies to International Renewable Energy Certificates (I-RECs) for that same generation, to avoid double-counting renewable attributes.
Does the REGO scheme continue after Australia's Renewable Energy Target ends in 2030?
Yes, per the knowledge-base context, while Australia's Renewable Energy Target ends in 2030, the REGO scheme continues beyond that date, providing ongoing mechanisms for documenting and trading renewable electricity attributes.
Where can I find information about buying and selling global RECs mentioned alongside the GO glossary entry?
The Northmore Gordon page links to a 'Buy and Sell Global RECs' service page (northmoregordon.com/services/trade-with-us/) alongside the Guarantee of Origin (GO) glossary entry.
