Carbon data rights certificates

Last updated 3 November 2025

What is the carbon data rights certificates？

Carbon data rights certificates (CDRCs) are tradable certificates issued under the Carbon Data Rights Certificate Standard 2025 (CDRC Standard).

The nominated registered agent for a registered holder (see subsection 6.(1) of the CDRC Standard for definitions) may apply for CDRCs for eligible BidCarbon removal units.

A nominated registered agent can apply for CDRCs by submitting an application for CDRCs in the BUC Registry.

Once an application for CDRCs has been received, the Operating Companies will determine the eligibility of CDRCs applied for - this process is called the 'validation' process - and will register eligible CDRCs in the BUC Registry.

Once a carbon data rights certificate (CDRC) is issued in the BidCarbon Unit and Certificate Registry, the holder may:

● deposit the CDRC with a Banking Corporation; or

● sell the CDRC through the CDRC markets.

A BidCarbon removal unit (BRU) is a standardized data result object derived from multi-source activity data, monitoring data and approved calculation methodologies, representing a verified quantity of carbon dioxide removal.

The tax definition of a digital asset is any digital representation of value recorded on a cryptographically secured, distributed ledger (blockchain) or similar technology.

For tax purposes, BidCarbon removal units (BRUs) are in different countries: 

For tax purposes

All applications for carbon data rights certificate must be made through the BidCarbon Unit and Certificate Registry (BUC Registry) which facilitates the creation, registration, transfer of CDRCs.

The nominated registered agent for a registered holder may apply for CDRCs for eligible BidCarbon removal unit.

All CDRC applications must be within the validity period of the certification of entitlement.

Requirement to change BUC Registry account permissions

If you would like other users to begin applying for CDRCs in an account, the account administrator will need to log into the BUC Registry and update the permissions for all relevant users.

Users without relevant permissions will be unable to enter carbon data and will not be able to apply for CDRCs.

The steps below set out what is involved in making and processing an CDRC application. Visit the links in each step for detailed guidance.

Step 1: before submitting a application for CDRCs

● Review before submitting a application for CDRCs

● Select an appropriate asset appraisal methodology

● Answer the standard validation questions and have them ready to submit along with your first claim

5 steps for applying and registering CDRCs

Once they have been issued by the BidCarbon removal unit, nominated persons may apply for carbon data rights certificates (CDRCs) for eligible BidCarbon removal unit. Before CDRCs can be sold or traded, they are assessed by the Operating Companies to ensure they are eligible for registration once an CDRC application fee is paid.

The Operating Companies uses a risk-based approach for the assessment of CDRC applications and uses a range of third-party information sources and supporting data analytics to determine that a CDRC application made by a nominated person is eligible for registration.

The Operating Companies may take up to 28 days to validate a application for CDRCs. You can track our CDRCs in the BUC Registry, including the ability to see how many CDRCs have been passed, failed, are pending or under assessment, or pending validation.

Failure of carbon data rights certificates

Nominated persons are responsible for ensuring they apply for the correct number of CDRCs in respect of CDRCs.

During the assessment process, the Operating Companies may require the submission of additional information to support your CDRC application and enable us to be satisfied certificates are eligible for registration. We may also determine that certificates are ineligible for registration, and therefore will be failed in the BUC Registry.

See failure of carbon data rights certificates for more information.

Communication made by the Operating Companies regarding CDRC applications is conducted through the carbon data of CDRCs page in the BUC Registry for each month.

This generates an automated email to the BidCarbon removal unit owner's nominated person account users providing notification of a request for further information.

Account administrators should monitor their email inbox for these messages.

Carbon data rights Certificate validation process

Ongoing compliance reviews

After the registration of a CDRC, and through the Category A asset appraisal report, the Operating Companies shall conduct ongoing reviews of BidCarbon removal units and previous applications made by nominated persons.

As a result of these reviews, the Operating Companies may request nominated persons to provide additional information relating to the application for a CDRC.

The Operating Companies may take action in response to any identified over-application of CDRCs that have been registered.

The Operating Company shall notify the designated personnel of any instances in which over-crediting or under-crediting by any unit has resulted in the over-issuance or under-issuance of carbon data rights certificates (CDRCs).

The Operating Companies shall also advise nominated persons of any identified over or under-application of certificates.
