Carbon data rights certificates

Last updated 2 May 2025

What is the carbon data rights certificates？

BidCarbon removal units (BRUs) are carbon credits earned within the BidCarbon Standard Scheme.

Carbon data rights certificates (CDRCs) are tradable certificates issued under the BidCarbon Standard Scheme.

The nominated person for an BidCarbon removal unit owner may create carbon data rights certificatess (CDRCs) for eligible BidCarbon removal unit.

A nominated person can create CDRCs by submitting a 'claim' for CDRCs in the BUC Registry. Once a claim for CDRCs has been received, the Operating Companies determines the eligibility of CDRCs created - this process is called the 'validation' process - and will register eligible CDRCs in the BUC Registry.

Registered CDRCs can be sold through the CDRC market.

A digital asset is stored electronically and can be bought, sold, owned, transferred or traded. 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 claims for CDRCs must be made through the BUC Registry which facilitates the creation, registration, transfer of CDRCs.

The nominated person for an BidCarbon removal unit owner may create carbon data rights certificates (CDRCs) for eligible BidCarbon removal unit.

All CDRCs must be created within 12 months of the date of issuance of the asset valuation report.

Requirement to change BUC Registry account permissions

If you would like other users to begin creating CDRCs in an account, the account administrator will need to log into the BUC Registry and update the permissions for all relevant users. Please ensure that 'enter carbon data' and 'create CDRCs' are selected (ticked) for all relevant users.

Users without relevant permissions will be unable to enter carbon data and will not be able to complete CDRC claims.

Most nominated persons submit claims monthly, quarterly or annually.

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

Step 1: before submitting a claim for CDRCs

● Review before submitting a claim for CDRCs.

● General formula for valuing carbon data assets.

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

5 steps for creating and registering CDRCs

Once they have been issued by the BidCarbon removal unit, nominated persons may create 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 creation fee is paid.

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

The Operating Companies may take up to 28 days to validate a claim 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 create the correct number BRUs of CDRCs.

During the assessment process, the Operating Companies may require the submission of additional information to support your CDRC claim 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 claims 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 an CDRC, and through the asset valuation reports (AVRs), the Operating Companies conducts ongoing reviews of BidCarbon removal unit and previous claims made by nominated persons. As a result of these reviews, the Operating Companies may request nominated persons to provide further information regarding the creation of an CDRC.

The Operating Companies may act in response to the over-creation of CDRCs that have been registered.

The Operating Companies advises nominated persons regarding any identified under-creation of certificates.

See the Operating Companies approach to dealing with over and under-crediting of certificates or units in the BidCarbon Standard Scheme.
