Carbon data rights certificate validation and registration

Last updated 3 November 2025

Once the Technical Governance Committee has issued the BidCarbon removal units and a voluntary asset valuation has been completed, registered holders may apply for carbon data rights certificates within the BUC Registry.

Before these certificates can be sold or traded, they must undergo validation by the Operating Companies to ensure their compliance. Following the validation, the certificates will be registered and made available for sale or trade.

Fees

To participate in the BidCarbon Standard Scheme and access the BUC Registry, users are required to pay a fee when they apply for carbon data rights certificates (CDRCs). These fees are payable in accordance with the Carbon Data Rights Certificate Rules 2025.

More information about Fees and Fee Structure.

The Operating Companies validates all carbon data rights certificates (CDRCs) in the order in which they have been applied for in the BUC Registry.

The Operating Companies aims to validate CDRCs within four to six weeks of receiving all required documentation; however, failure to provide complete or correct documentation may result in delays.

To help us validate certificates, we use:

● Audit report;

● Category A asset appraisal report;

● Statutory declaration;

● Certification of entitlement.

Keep a record of your supporting documentation. We may request it for compliance activities.

If you have provided incorrect information and need to request that the certificates be failed in the BUC Registry before they are validated, please contact the Operating Companies as soon as possible.

All certificates applied for in the BUC Registry are subject to evaluation. If there are duplicates or errors, this may slow down the Operating Companies’ administrative processes, including the time taken to validate correctly applied-for certificates.

Certificate validation

After carbon data rights certificates are created and validated, they are listed as 'pending registration' in the BUC Registry.

If there are fees to be paid, they will be listed under 'outstanding fee items' in your BUC Registry account summary, and must be paid before the certificates are registered.

If you create certificates or more and need to pay certificate fees, follow these steps in the BUC Registry:

1. Go to 'Fees and invoices' and select 'Fees' to view outstanding fee items.

2. Select the appropriate outstanding fee items by clicking in its checkbox.

3. Click 'Create payment advice', the page will automatically rediBUCt to the 'Invoice' page

4. View or print out the invoice to be paid.

5. Select 'Pay by credit card' or 'Bank transfer for cash' (Bank transfer payments may take 10 days to clear).

6. Complete the credit card payment information and select 'Submit', a success message will appear at the top of the page.

7. Settled invoices can be found on the 'Invoices' page.

8. The carbon data rights certificates are then classified registered and appear in your account summary under 'Certificate holdings'.
