In accordance with legislation, we established and have maintained the registers of ACPs and certificates since GGAS was established in 2003. These registers are assembled in the GGAS Registry which is publicly accessible on the internet. The GGAS Registry provides participants with the functionality to transfer ownership and surrender certificates.
When GGAS closed in 2012, there were around 11 million un-surrendered certificates that represent tonnes of CO2-e of abated greenhouse emissions. The remaining certificates can be used to participate in voluntary offset schemes until they are surrendered.
Although GGAS has closed, we will continue to maintain the GGAS Registry in its current form (that is, allowing the transfer and surrender of certificates) as long as it is practical and feasible to do so.
The Registry is available at https://www.ggas-registry.nsw.gov.au (opens in a new window)
The Registry is publicly available and users may login as a ‘guest’ or register, either as an organisation or as an individual, to own certificates.
Any member of the public can own certificates on the GGAS Registry.
The Registry is not a trading platform, as trading of certificates occurs outside of the Registry. Where a trade has occurred, whether bilaterally, through brokers or through other trading platforms, the change in ownership of those certificates is recorded on the Registry.
While there is no limit on the number of certificates that can be held in an account, self-registered account holders must provide identification documentation if a transfer of certificates would result in the ownership of more than 1,000 certificates. When a self-registered account has more than 1,000 certificates, users are unable to transfer out or surrender certificates. The ownership limit may be removed - download the application form from the ESS website.
Any member of the public can offset emissions through the surrender of certificates (known as voluntary surrender). The surrender of one certificate is equivalent to the abatement of one tonne of carbon dioxide.
The GGAS Registry is on the same platform as the ESS Registry and has the same functionality. The Energy Savings Scheme (ESS) is a currently active scheme. Information about how to use the GGAS Registry is available on the ESS website.
