Puro.earth business model and fee structure

When Puro.earth was founded in 2019, there was no crediting program for engineered carbon removal. This gave us a blank slate to define a value proposition that is designed to enable the growth of the nascent carbon removal market while emphasizing simplicity, cost-efficiency, and transparency. Under the Puro Standard, we issue CO2 Removal Certificates, CORCs, that are sold in the carbon markets through third-party marketplaces or directly by our suppliers.

Important Notice: Fee Model Update

This fee model will soon be replaced. Starting October 1st, we will be implementing a new fee structure.

Transparent and simple cost structure

Puro earth has 2 sources of revenue:

1. Annual platform membership fee​

Puro.earth charges a €1400 annual membership fee that includes a Puro Registry Account where account holders can manage and retire CORCs. Users also need to sign the Platform Agreement. 

We do not charge extra for opening, closing, or reactivating accounts. 

2. The Puro.earth service fee​

The service fee is applied to the supplier when the CORC or credit is traded for the first time. It is based on the volume of estimated annual Output of CORCs AND the price level of CORCs. The service fee is then taken from the total trade value.

Annual output Price level 1 Price level 2 Price level 3 Price level 4 Price level 5
Min Max 0.0-50.0€ 51.0-100.0€ 101.0-300.0€ 301.0-600.0€ 601.0-0.0€
Volume level 1 0 2000 20% 12% 10% 10% 7%
Volume level 2 2001 20000 10% 8% 6% 5.5% 5%
Volume level 3 20001 50000 7.5% 7% 5.5% 5% 3%
Volume level 4 50001 100000 7% 6% 5% 4% 2%
Volume level 5 100001 300000 6% 5% 4% 2% 1%
Volume level 6 300001 500000 5% 3% 2% 1% 0.4%
Volume level 7 500001 1000000 4% 2.5% 1.5% 0.8% 0.3%
Volume level 8 1000001 5000000 3% 2% 1% 0.6% 0.25%
Volume level 9 5000001 0 2% 1.5% 0.7% 0.35% 0.2%

In the case of pre-payment of the CORCs or credits, 50% of the estimated Service Fee will be invoiced when the pre-payment occurs. The remaining balance will be invoiced once the final volume and price are known and the ownership of the CORCs or credit is changed.

The service fee covers the comprehensive process of the certification journey, including but not limited to registration, audit preparation, verification, validation, output audit, issuance, and transfer of ownership. Additionally, it accounts for methodology development and oversight by the Advisory Board.

It's important to note that costs incurred due to factors beyond the Service Provider's control, such as the inability to provide sufficient evidence for the audit package, will be the responsibility of the supplier. Any charges will only be applied with the explicit approval of the supplier. Refusal to bear such costs may result in the discontinuation of the certification journey

By design, our service fee is simple, transparent and - based on estimates produced by a top tier consulting firm - one of the most cost-efficient means of issuing credits.

The service fee is independent from the sales channel that was used for the transaction. In other words, the service fee is the same regardless of whether the supplier had negotiated a bilateral deal between with the buyer or used a third-party broker or marketplace. Puro.earth does not derive any revenue from brokerage services. Puro.earth is not a party or a beneficiary in the market transaction. Puro.earth holds no equity in any members of the platform, and we have not established any revenue sharing arrangements with the account holders. 

The listing price on third-party marketplaces already includes the Puro.earth service fee.

Secondary trades

When a secondary trade occurs, Puro.earth charges a fee to the CORC holder to register the change of ownership in the Puro Registry. This fee is dependent on the volume of the CORCs that are traded.

If the CORC or credit has been traded at least once and it is retired by the owner so that the Beneficiary is another legal entity, no Secondary Trading Service Fee is charged.
