MRV (Measurement, Reporting and Verification) is the technical foundation of every carbon credit. Here is exactly how ours works, what it costs, and why it matters.
In 2023, investigative reporting by the Guardian and analysis by Sylvera found that a significant proportion of REDD+ (forest protection) credits issued by major registries did not represent real emissions reductions. The projects existed. The credits were issued. But the monitoring methodology relied on satellite imagery and statistical estimation — not ground-level verification. When rigorous methods were applied retrospectively, the actual sequestration was a fraction of what was claimed.
This was an MRV failure. Not a carbon market concept failure — an infrastructure failure. The market lacked the tools to know what was actually happening on the ground. Buyers who purchased those credits in good faith for their net-zero claims were left exposed.
The entire case for high-quality carbon credits rests on the answer to one question: did the carbon sequestration or emission reduction actually happen, and can you prove it? Machine-verified MRV — GPS chains, SCADA logs, EBC lab certificates, permanent sample plots — exists to make that answer verifiable by any auditor, any rating agency, any regulatory body. It is not optional infrastructure. It is the product.
Cula is the digital MRV platform we deploy on Biochar CDR projects. It provides a six-link GPS chain from biomass collection to soil application — creating a tamper-resistant audit trail that auto-pushes to the Puro.earth registry API without manual data entry.
Each link in the chain captures a GPS coordinate, a timestamp, a weight measurement, and a unique batch ID — meaning no credit can be issued for biomass that was never collected, or biochar that was never applied to soil.
Auto-push to Puro.earth API: When a batch completes all six chain links, the aggregated data record is automatically transmitted to the Puro.earth registry for credit issuance verification. No manual data entry. No spreadsheet. The data goes directly from the field device to the registry.
GPS field tag, NIR moisture meter reading, wet weight measurement, Aadhaar farmer ID verification, Cula mobile app capture. Every kilogram of rice husk or bagasse is attributed to a named, verified farmer.
Bridge scale weight, moisture retest, batch ID assignment, timestamp. Confirms the biomass volume received at the kiln matches the collection record.
SCADA continuous data log: temperature (target 500°C), residence time, input weight, output weight. Machine data — not operator entry. Cannot be retrospectively modified.
Quarterly CHNS analysis by EBC-accredited independent laboratory. H:Corg ratio, BET surface area, PAH content, heavy metals panel. Independent certificates issued directly to Puro.earth — not via Stasis Carbon.
GPS-tagged delivery vehicle, Aadhaar-linked farmer receipt, kilogram-per-bag logging. Confirms the biochar product reached the intended application site.
Agronomist GPS verification of application site, annual 10% soil sampling, soil organic carbon delta measurement. Confirms biochar was incorporated into soil — not stockpiled or diverted.
India's carbon credit infrastructure and marketplace platform. Machine-verified MRV, independent ratings, insurer-backed credits.
