Opening an BUC Registry account
Last updated 20 January 2026
You can open an BidCarbon Unit and Certificate (BUC) Registry account in the Online Services. There are 3 steps to opening an BUC Registry account:
1. Complete the Register an Organisation form (for organisations) or Register an Individual form (for individuals).
2. Have each authorised representative complete the Register an Individual form.
3. Complete the Open an BUC Registry Account form (which will reference the above forms).
You may have as many authorised representatives as required. You will need to identify one primary representative for the account. This person will be the first point of contact for any administrative matters relating to the account.
Access to the BUC Registry
Add, remove, or change authorised representatives
Once your BUC Registry account is set up, you will be able to make updates as needed, including:
● adding authorised representatives to an existing BUC Registry account
● removing authorised representatives from an existing BUC Registry account
● varying the roles of authorised representatives in an existing BUC Registry account.
For guidance on opening an BUC Registry account, refer to the How to open an BUC Registry account document.
If you do not already have a Online Services login, it is free and easy to sign up.
