Carbon removal buyers face a hard problem: how do you know a claimed tonne of CO₂ removal actually happened? For Enhanced Rock Weathering, the answer depends entirely on the rigor of the measurement, reporting, and verification (MRV) protocol behind it.
Why we chose Isometric EW v1.2
Isometric's Enhanced Weathering Protocol v1.2 is widely regarded as the most conservative and scientifically rigorous ERW methodology available today. It requires:
- Primary data collection across soil, water, and crop samples — not modelled estimates alone
- Conservative uncertainty deductions that err against overclaiming
- Third-party laboratory verification, in our case through partners at IARI-PUSA and JNU
- Full traceability from rock source to field application to sampling
What this means for buyers
When you purchase a Terrasols carbon removal credit, it has been verified against a protocol designed to withstand scrutiny — not just from auditors, but from the scientific community. This matters more every year, as buyers face growing pressure to prove additionality and permanence in their climate claims.
Where we're headed
We're building DHARA, our primary-data dMRV platform, to make this process faster and more transparent as we scale from 500 tonnes toward 50,000 tonnes of annual supply. Rigor doesn't have to mean slow — it has to mean trustworthy.
