A Biochar Project at Satyapura

Audit Analysis

A newly validated biochar carbon-removal project on the Isometric registry with a verified combined additionality test and no reversal events, but hampered by a project-specific baseline, a 0% leakage deduction justified only as 'deemed negligible,' an aggressive 200-year permanence claim, and 22 material findings with 20 outstanding corrective actions at the time of validation. The extremely short 13-day monitoring window and the very early stage of the project limit the evidentiary base for scoring.

Project Description

Red Flags

• ⚠200-year permanence claim with only a 2% buffer pool is aggressive for a biochar project in its first monitoring period
• ⚠0% leakage deduction justified solely as 'deemed negligible' without a quantified assessment, despite feedstock (biomass) having alternative uses
• ⚠22 material findings and 20 corrective actions were open at validation, including an initial mercury exceedance (2 g t⁻¹ DM) that required re-testing by three additional labs
• ⚠Contradiction between the PDD (27,890 tCO₂) and the validation report (34,931 tCO₂) for the lifetime ex-ante estimate, a ~25% gap
• ⚠H₂ was not tested in flue-gas emissions; compliance is deferred to a future protocol transition (v1.2)
