True Fee Structure

This new service fee structure is designed to be transparent, predictable, and scalable. It decouples the cost from the number of issued CORCs and no longer relies on the value of the credit.  
It rewards for high volumes and scalability and accounts for varying levels of audit complexity, and simplifies the fee model by removing the secondary trading fee and introducing a fixed per-unit retirement fee.

Starting October 1st, we are transitioning to a new fee model. To help you prepare, we have provided a link to the current fee model which will remain in effect until September 30th.

Every account holder will automatically receive a new Platform Agreement on August 30th, effective October 1st. No action will be needed on the account holder's part, unless they choose to terminate their agreement within 30 days.

Transparent and Simple Cost Structure

1. Annual Fee

After signing the Platform Agreement, the organization is created into our registry and the users get access to their main account. Is is possible to create the necessary number of subaccounts to manage credits. The Annual Fee is 1400€ per 12 month period, starting from the date of signing.

2. The Service Fee

The service fee is paid by the supplier when the CORC or credit is traded for the first time. There is a fixed fee per CORC which is based on the reported cumulative volume of CORCs for the past 12 months. There is a steep discount per CORC as the annual output volume grows.  We do not charge extra for opening, closing, or reactivating accounts.

Overview of the New Service Fee Structure

1. Fixed Fee Per CORC

  • The service fee is a fixed amount per CORC = CO2 Removal Credit
  • The fee is determined by the volume of CORCs reported in the Output Report, which is submitted by the CO2 Removal Supplier to the Issuing Body. 

2. Volume-Based Pricing

  • The cost per CORC decreases as the reported output volume increases. 

  • The volume step is determined by the reported output volume over the last 364 days.

  • There are 37 discount steps that reduce the cost by a factor of 30 as volume grows, providing a more granular and scalable model.

3. Discounts and Fees

  • Issuance Payment Discount: Suppliers paying the service fee at the time of issuance receive a 5% discount. 
  • Retirement Fee: A new retirement fee of €0.25 per retired CORC is charged to the account holder performing the retirement. 

All long-term offtake trades that have been agreed and announced to by the end of September will be exempt from the Retirement Fee. 

The Secondary Trading Fee has been removed from the new model.

4. Verification Complexity Level Premium

A premium is added for methodologies that are more complex to quantify and verify.

5. Pooling Admin Fee

A fee of €2,000 per facility per year is charged for pooling volumes, invoiced when the pooling request is made.

Calculation example

1. One facility, one batch reported

How to calculate?

  • Determine Base Cost: Use the reported output volume to find the base cost per CORC from the table above.

  • Apply Complexity Premiums: Adjust the base cost based on the methodology used and any additional SDG claims to get the fee per CORC. 

  • Calculate Total Cost: Multiply the fee per CORC with the number of CORCs reported.  

Example Calculation: 

  • Suppose a supplier reports 10,000 CORCs. Base cost is €7.50 per CORC (from the Service Fee Table)

  • If using Enhanced Rock Weathering methodology, add 12% premium: €7.50 * 1.12 = €8.40 per CORC. 

  • Auditor verifies 9,900 CORCs: Total cost remains €84,000. 

  • Per CORC cost adjusts to €84,000 / 9,900 = €8,48 per CORC. 

2. One facility, three batches reported in the first year

Second calculation example examines the situation where the supplier wishes to make an early issuance to make sure the process is auditable and / or needs to make the first delivery of CORCs early. For the sake of simplicity, we assume each reported volume matches the verified volume.  

In terms of absolute cost, it makes sense to report credits in larger volumes in the first year, but the difference is not great if the supplier needs to get some cash flow earlier or wants to demonstrate the delivery capability to investors or other stakeholders.  

3. Three facilities

Third example examines the situation where a project developer has three projects, each from different methodologies.
