Issuing a verified carbon credit isn’t simple. It requires precise measurement, strict compliance with evolving regulations, and third-party validation. InPlanet recently announced its development and delivery of certified carbon credits in Enhanced Rock Weathering (ERW) as the first in the world, a milestone for the entire Carbon Dioxide Removal (CDR) industry. As InPlanet’s Head of Carbon, Dr. Matthew Clarkson put it:

“To allow us to have the standard to issue that credit, we have to align with scientific best practices, follow strict protocols, and pass independent validation. It’s complex, but it’s what makes our credits truly credible.”

The journey of an InPlanet credit starts in the field. Our team spreads finely crushed basalt rock on farmland in Brazil, triggering a natural reaction that removes CO₂ from the air. But removing CO₂ is just the first step; proving it is what really matters.

How we verify our credits

In order to make this possible, InPlanet worked closely with Isometric, the independent credit issuer responsible for ensuring our carbon removal meets the highest standards. They oversee the entire verification process, ensuring our methodology follows the latest and most rigorous scientific research and regulatory requirements. Dr. Clarkson explained:

“Isometric is the organization that actually does the graduation. They are the ones who can release the credit.”

It doesn’t stop there. Once our data is collected and processed, an independent Validation & Verification Body (VVB), in our case, Eco Engineers, steps in to assess our work. They meticulously and independently review everything: soil and water samples, CO₂ removal calculations, and compliance with Isometric’s protocol. Only then do we receive the official stamp of approval. Dr. Clarkson emphasized:

“This is what gives us a verified credit, not just a delivered credit. While many companies claim to remove CO₂ we are among the first to be officially verified.

From InPlanet to the Buyer: The Path of a Verified Credit

Once verified, our carbon credits enter the market. Buyers, often large corporations, purchase credits to offset their emissions. Some work with intermediaries, which are market platforms that help match buyers with high-integrity credits like ours.

Dr. Clarkson went on to explain that:

“Intermediaries link us to those buyers, and they ensure our credits reach the right market. With growing concerns about greenwashing, verification has never been more important. Companies want to be sure their climate investments are real, measurable, and scientifically sound. At InPlanet, we’ve built a process that removes doubt, ensuring every credit we issue is backed by hard data and independent oversight.”

The future of verified carbon credits

Carbon markets are evolving, and so are the regulations that govern them. Organizations like the EU Commission and the Integrity Council for the Voluntary Carbon Market (ICVCM) are setting new standards to ensure that only genuine CO₂ removals make it into the market. Dr. Clarkson shared:

“This methodology has to adhere to the best available science, and that’s always changing. 

That’s why our team at InPlanet remains committed to continuous innovation, rigorous data collection, and absolute transparency. The world doesn’t need more carbon credit promises, it needs verified action. And that’s exactly what we deliver.
