Online support and helpdesk
In the right hand corner of most pages of the Registry is a help icon that accesses online help to assist with the use of the Registry or download the User Guide.
The Registry Helpdesk is available on 1800 006 797 (8:30am – 5:30pm Monday to Friday, excluding NSW public holidays) or registry@greenhousegas.nsw.gov.au. The helpdesk can help with queries regarding the queries or problems with the use of the Registry and forgotten passwords.
Registry charges
There is currently no charge for the transfer of certificates on the Registry. There is, however, a $0.70 charge imposed on the registration of ESCs at the time of creation. Certificates remain on hold until payment for registration has been received by the Scheme Administrator. Payments for certificate creation must be received within 60 days of creation of certificates.
Certificate trading
The Registry is not a trading platform as trading of certificates occurs outside of the Registry. When such a trade occurs, whether bilaterally, through brokers or through other trading platforms, the change in ownership of those certificates is recorded on the Registry.
Ownership limits
There is no limit on the number of certificates that can be held in an account, however self registered accounts are initially limited to 1,000 certificates. This limit can be removed at the request of the account owner. Click here for the application form for certificate limit removal.
Creating a Registry account
Any member of the public can create their own Registry account. To create your own Registry account, logon via the ‘Guest’ login and select ‘Become Registered’.
Creating certificates
All accredited organisations may create certificates within the limits of their accreditation. To create certificates select ‘Create Certificates’ from the home page and follow the prompts. As mentioned above, there are charges for the creation of certificates.
Transferring certificates
The Registry tracks and records ownership history of all certificates. To transfer certificates select ‘Transfer Certificates’ from the home page and follow the prompts. The transfer process for certificates must be completed within 60 days of initiating the transfer of certificates.
Surrendering certificates
All owners of certificates may surrender certificates to meet targets or voluntary offset programmes. To surrender certificates select ‘Surrender Certificates’ from the home page. Note that there are certain times of the year when the surrender window is closed. Information regarding voluntary surrenders can be found on the voluntary surrender factsheet.
Managing user accounts
Each Registry account can have multiple user accounts and at least one of these user accounts should be a Key User. The Key User is able to add, disable and manage levels of access for all user accounts within their organisation for other staff. To manage user accounts select ‘User Maintenance’ from the bottom right of the home page.
