Methodologies for carbon removal
The Puro Standard provides quantification methodologies for carbon removal. We have certified over 100 engineered carbon removal projects under the Puro Standard, resulting in the issuance of more than 1.5 million CO2 Removal Certificates (CORCs) in the Puro Registry as verified, traceable, investable assets.
We replace traditional certification bottlenecks with commercial pragmatism. Through high-frequency issuance and a digital-first workflow, we help you monetize your removals faster without compromising on scientific integrity.
Puro.earth’s digital suite transforms technical milestones into financial performance. By bridging the gap from early-stage bankability validation to a professionalized certification ecosystem – driven by automated data integration and high-frequency issuance – we accelerate revenue cycles and optimize liquidity. Our infrastructure is built for monetizable, industrial-scale carbon removal operations.
A premium service for on-demand issuance helps suppliers convert removed CO2 into revenue faster, supporting improved cash flow, planning certainty, and market responsiveness.
“The reason for us picking Puro, was that we saw a lot of quality in the platform, in the standard. We also saw that it was being kept updated by a very capable team and this team was very flexible in terms of engaging in dialogue and understanding where we were as a company.

Bridging the investment gap
Large-scale carbon removal requires more than just science. It requires the qualities to become a financeable asset class. We are the trusted global benchmark – we create paths from early assessment to certification and from certification to bankability. As a result, the removed CO2 is turned into financial credits.

Our fee structure: transparent, predictable, and scalable
Puro.earth service fee is transparent, predictable, and scalable. Our fees do not rely on the value of the credit. We reward high volumes and scalability and account for varying levels of audit complexity.
Our support extends beyond issuing certificates. We guide projects through the entire certification process and manage third-party verification. By covering verification costs, we move the cost of certification from an upfront expense to a shared success model.

The Puro Registry is used for tracking the entire lifecycle of the credit. As we discontinued the secondary trading fee which would incur costs for each transaction, but was not welcomed by some commodity traders, we decided to move to single fixed cost at the end of the lifecycle to cover some of the costs of maintaining the system.
The new fee model will be operational at the beginning of October 2024. This means that for any transactions happening after that date, the new service fee applies. For existing CO2 Removal suppliers, the fees will be based on the cumulative volume over the last 364 days from the date of issuance of their CORCs.
On February 2, 2025, Puro implemented a new minimum CORC fee structure to enhance the efficiency of our audit processes and scale the CDR industry better, faster, and stronger. We also implemented a waiver that is a significant advantage for our customers that meet certain requirements, as it eliminates the Retirement Fee, making long-term offtake trades more cost-effective and attractive.
Register your interest here. For a supplier to be issued CO2 Removal Certificates (CORCs) the product that sequesters carbon and the production facility must be verified.
Once initially qualified by the Puro Team, there are three steps to making a claim that your production is carbon net-negative:
You must have documented evidence of the carbon footprint of your production: an Environmental Product Declaration (EPD) or a Lifecycle Assessment (LCA) for the cradle-to-gate carbon footprint of your production. If you don’t have an LCA or EPD, we can put you in contact with companies who can do it for you.
Send the EPD or LCA document to your account manager.
When we have this information, we will start a verification process by contacting you within the coming days.
This is the output volume that a CO2 removal supplier reports to the issuing body when submitting their production output report.
