Buy and sell carbon data rights certificates (CDRCs)

Last updated 20 May 2025

Once carbon data rights certificates (CDRCs) have been created, traders and businesses can buy and sell them through the secondary market or BidCarbon marketplace.

Any individual with a registered person account can trade in CDRCs. However, most CDRCs are purchased by compliance or voluntary demand entities to meet their offsetting requirements.

Before you buy or sell CDRCs

Before you trade CDRCs, there are some important things you should know.

There is no set price for CDRCs. Pricing is dependent on trading within the open market or through the BidCarbon marketplace.

The seller should only transfer certificate ownership after receiving payment from the buyer.

The BidCarbon Foundation have no role in the sale/trade of certificates.

Non-payment issues are a contractual matter between you and the other parties involved.

Learn more about the supply and demand of CDRCs on the BidCarbon marketplace.

Pricing in the open and secondary markets

We don't set the prices for certificates in the open and secondary markets. We also can't interfere in negotiations or payments of certificates. All negotiations and payments are made outside of the BUC Registry.

Selling CDRCs

You can sell CDRCs on the BidCarbon Marketplace to socially responsible entities, CDRC traders and individuals.

To sell CDRCs:

1. Contact the BidCarbon Carbon Trading Company and negotiate the quantity, price and payment method.

2. Enter into a supplier agreement with them.

3. Make payment arrangements and receive payment.

4. Transfer CDRCs to the buyer in the BUC Registry.

Buyers must accept the transfer in the BUC Registry.

CDRCs sales

The sale of CDRCs is a commercial contract for the sale of goods. The sale should be accompanied by complete and accurate paperwork.

Make sure you receive payment before you transfer CDRCs in the BUC Registry.

You can withdraw an CDRC transfer in the BUC Registry under 'certificate transfers'.

You cannot withdraw if the buyer has already accepted the transfer.

Buy directly from the BidCarbon marketplace

To buy directly, you must have a CDRCs purchase agreement with that BidCarbon Standard Scheme project.

A CDRC purchase agreement is a contract between an entity and a BidCarbon Standard Scheme project developer. It allows the entity to purchase CDRCs created by the BidCarbon Standard Scheme project developer.

You can make the agreement before building the BidCarbon Standard Scheme project or at a later stage. Signing before building is the best way to secure financial backing for the project.

Contracted CDRC prices may be lower than the current market price.
