Carbon Removal Credits:
‍how it works

We sell credits that represent a tonne of CO2e removed through our operations and partnerships.

This finances more enhanced rock weathering — and more carbon removal that benefits African farmers.

Measuring carbon removed through enhanced rock weathering is more precise than ever, thanks to scientists whose models have advanced the field in the past few years alone.

Precision is crucial. We need it to prove climate impact and also prove the integrity of carbon markets that depend on strict measurement, reporting, and verification (MRV) for public trust.

We are proud to be in an emerging ecosystem of high-integrity carbon removers following third-party protocols to prove their impact. Isometric, our verification partner, has the industry's most stringent standards for enhanced rock weathering.

We subscribe to the Core Carbon Principles of the Integrity Council for the Voluntary Carbon Markets, the Oxford Principles on Net Zero Aligned Carbon Offsetting, and others that have achieved consensus in the voluntary carbon markets. These include:

Additionality: every project is removing carbon that would not otherwise be removed, absent the project
Permanence: carbon is removed for at least 1,000+ and ideally 10,000+ years
Robust quantification: as many data points as possible are analysed to prove the carbon removal impact
Transparency: measurement methods are agreed through scientific peer review, and data are disclosed publicly
Sustainable development: Affected communities are brought into the decision-making, as well as the economic benefits, of the projects

Step 1:

A company commits to enhanced rock weathering to help meet its net zero goals — after reducing its emissions as much as possible.  The company orders a certain tonnage of carbon dioxide equivalent (CO2e) removed. The tonnage aligns with its carbon accounting.

Step 2:

Our operational team calculates how much rock powder is needed to remove the CO2.

Step 3:

We spread the rock powder in fields and accurately measure the carbon drawdown, taking into account any emissions generated by the process.

Step 4:

Isometric, our verification partner, generates the credits after they confirm that the process meets their Enhanced Rock Weathering Protocol.

Step 5:

Credits are transferred to the buying company. The company uses them to prove progress in sustainability. The credits remain trackable on the Isometric Registry, so they cannot be held by more than one buyer.
