Carbon Data Rights Certificates

Last updated 3 May 2026

What is the Carbon Data Rights Certificates?

Carbon Data Rights Certificates (CDRCs) are tradable certificates issued in accordance with the Carbon Data Rights Certificate Standard 2025 (the “CDRC Standard”). CDRCs represent structured data products derived from eligible BidCarbon Removal Units (BRUs), and are used for the management, transfer, and application of carbon-related data outputs.

A nominated registered agent, acting on behalf of a registered holder (as defined in subsection 6.(1) of the CDRC Standard), may apply for the issuance of CDRCs corresponding to eligible BRUs. Applications must be submitted through the BidCarbon Unit and Certificate Registry (BUC Registry).

Upon receipt of an application, BidCarbon Big Data Chengdu Limited (the “Operating Company”) conducts an eligibility assessment of the underlying BRUs. This assessment process, referred to as the “validation” process, determines whether the submitted BRUs satisfy the requirements for CDRC issuance under the applicable standard.

Where the application is validated, the corresponding CDRCs are issued and recorded in the BUC Registry under the account of the registered holder.

Once issued, a CDRC may be:

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 equivalent.

The tax definition of a digital asset generally refers to a digital representation of value recorded on a cryptographically secured distributed ledger (blockchain) or similar technology.

For tax purposes, the classification of BidCarbon Removal Units (BRUs) varies across jurisdictions and depends on their legal characteristics, technological implementation, and functional use.

Country/region

BRUs are considered to be

Chinese mainland

BidCarbon Removal Units may be recognised as data resources, and classified as intangible assets or inventories, depending on their intended use and applicable accounting framework.

United States

For U.S. tax purposes, BRUs are not explicitly defined under current tax law. Depending on their characteristics, they may be treated as intangible property, inventory, or other forms of value representation, rather than automatically classified as digital assets.

United Kingdom

For UK tax purposes, BRUs are not specifically classified as digital assets. Their treatment depends on their economic function and may fall within intangible property or trading assets, subject to HMRC interpretation.

BRUs are, in principle, considered data resources or digital assets in other countries and regions. Your local accountant is the best person to ask about how you are taxed in your home country.

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.

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.
