Enhanced Weathering 
at Isometric

Scientific rigor simplified

Make verification painless with Isometric

Isometric’s Enhanced Weathering Protocol is the highest quality protocol on the market.

When combined with Isometric’s digital MRV (dMRV) platform, you can quickly and easily submit data for verification—saving your team time and money.

Used By

A rigorous protocol that works for you

Working with the Enhanced Weathering protocol ensures credits are only issued when carbon dioxide has been durably removed from the atmosphere—creating confidence for buyers and suppliers.

What’s in the protocol

Sampling

Sampling is critical to issuing Enhanced Weathering credits because measurements from soil and porewater are needed to verify carbon removal. Isometric works with suppliers to ensure their sampling program meets the protocol. The amount of samples needed is flexible and varies by project.

For sampling to be compliant under the protocol:

  • Measurements taken in control and treatment plots should accurately represent a project
  • Chemical analysis should be used in control and treatment plots

No other protocols give clear guidance like this on the type of sampling needed to verify carbon removal via enhanced weathering.

Measurements

Direct measurements are needed to ensure Enhanced Weathering removes carbon because existing models are not yet robust enough.

Measurements required under the protocol include:

  • Direct measurements over the full project area
  • Allocating 2.5% of the project area for both treatment and control plots

Other protocols allow crediting with fewer measurements and rely more heavily on models.

Uncertainty

Soil chemistry is extremely complex, meaning it can be difficult to confirm that Enhanced Weathering removed carbon dioxide from the atmosphere.

To verify removal, the protocol requires:

  • A statistically significant signal that demonstrates the weathering process took place, with a minimum 95% confidence threshold
  • Cross validation of weathering signal (from soil and aqueous measurements)

Statistical significance ensures robust quantification and avoids over-crediting. Other protocols do not specify statistical significance thresholds.

Mining Science

Easy to use verification tools

Enhanced Weathering data is complex. Calculating total carbon removals per project can be daunting.

Isometric’s digital MRV (dMRV) platform takes the guesswork out of calculating net removals and makes verification quick and painless.

Submit easily

Any supplier or software provider can submit data via the dMRV platform, saving your team time and increasing the accuracy of your reporting.

Verify quickly

The platform helps verifiers complete robust audits, quickly—meaning suppliers can get credits issued within a month of data submission.

Automated scale

Whether you have a pilot deployment or large scale sites, the platform scales with you. Adding more sites is straightforward and doesn’t create extra manual work.
