BidCarbon removal units

The BidCarbon Foundation offers incentives in the form of BidCarbon removal units (BRUs) to promote carbon abatement activities. BRUs can be earned by eligible BidCarbon Standard Scheme projects that reduce or avoid emissions.

Last updated 2 May 2024

BidCarbon removal units (BRUs) are an improvement on traditional carbon credit units (CCUs). 

Technical Governance Committee (TGC) Under the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol, BRUs are issued within or outside the UK to reward emissions that are emissions stored or avoided through eligible BidCarbon Standard Scheme project activities. Each BRU issued represents one tonne of carbon dioxide equivalent (tCO2-e) greenhouse gases stored or avoided by an eligible project under the BidCarbon Standard Scheme.

All carbon data from BidCarbon Standard Scheme projects is acquired using metrological or measuring equipment. It is digitally monitored, reported, and validated. A digital representation of a BRUs includes a digital image of a carbon credit created using blockchain technology.

Some countries permit the inclusion of BRUs as data resources or digital assets on corporate balance sheets. This represents the most transparent and verifiable method of presenting carbon data, ensuring excellence in environmental accountability and financial integration.

Read our statement setting out a concise description of the characteristics of BidCarbon removal units (BRUs).

About BidCarbon data units

BRUs are issued to individuals or businesses that run eligible projects under the BidCarbon Standard Scheme. Participants can earn BRUs for every tCO2-e their project avoids emitting or stores.

To register a project, the eligibility criteria must be met. Ongoing monitoring, reporting, and auditing requirements are also necessary.

To learn more about participating in the BidCarbon Standard Scheme, please refer to the provided resources.

Earning BRUs

Participants may choose to sell balance sheet BRUs on the secondary market, or they may choose to sell BRUs to the BidCarbon Climate Trading Company, which can provide financial incentives for businesses and individuals to participate in BidCarbon Standard Programme projects.

Secondary market 

Any issuance, transfer or sale of BidCarbon data units (BRUs) is neither considered a supply of goods nor a supply of services, i.e. it is considered an excluded transaction. However, the sale of Carbon Data Rights Certificates (CDRCs) is considered a commercial contract for the sale of goods.

If you wish to sell BRUs in the Secondary Market or BidCarbon Marketplace, you must provide the necessary documentation to create carbon data rights certificates for your BRUs.

Private buyers, purchase CDRCs to voluntarily offset their carbon footprint or meet emissions reduction obligations.

The value of BRUs is subject to market forces of supply and demand.

Carbon removal contracts

BidCarbon Standard Scheme participants can also sell BRUs from their project to the BidCarbon Climate Trading Company through a carbon removal contract.

Under a carbon removal contract:

participants agree to deliver BRUs to the BidCarbon Climate Trading Company

the BidCarbon Climate Trading Company agrees to buy their BRUs at a fixed price (Primary producers).

Find out more about carbon removal contracts.

Sourcing CDRCs

To source CDRCs, you can:

search the CDR exchange to find CDRCs for sale

search the Carbon data rights certificates reports to find parties that may have CDRCs for sale

establish an BidCarbon Standard Scheme project to generate CDRCs.

Buying and selling balance sheet assets

Participants running BidCarbon Standard Scheme projects may need to surrender BRUs if they were issued:

based on false or misleading information, or

for a sequestration offsets project that has had its registration revoked, or 

for a sequestration offsets project with a complete or partial reversal of sequestration.

Moreover, participants can voluntarily relinquish BRUs to:

terminate a sequestration offsets project

In order to terminate a carbon maintenance obligation for a project area.

A court may require the surrender of BRUs and CDRCs that were fraudulently obtained.

If a person is required to relinquish BRUs, the number of BRUs to be relinquished can be deducted from any BRUs that are to be issued to them. This way, the person will be considered to have relinquished the necessary number of BRUs without any additional action required.

Once a BRU in a registered CDRC has been relinquished, that CDRC is invalidated and you must surrender the certificate.

Relinquishing BRUs
