Audit Analysis

CSI-Hardin is a very early-stage Puro.earth biomass storage project (PDD July 2024, first verification October 2024) with a 5-month monitoring window. While DNV verified the project with no material findings or corrective actions, critical integrity elements—buffer pool, leakage treatment, and safeguards documentation—are entirely absent from the extracted record, leaving meaningful gaps for a project type with inherent reversal and diversion risk.

Red Flags

  • No buffer pool or permanence risk mitigation identified for a biomass storage project with inherent reversal risk (fire, pest, harvest)
  • Leakage deduction and justification are entirely absent from both the PDD and verification report
  • No safeguards documentation found: FPIC, grievance mechanism, and safeguards mentions are all unrecorded
  • Internal contradiction in the verification report: both 102.75 and 3,248.69 tCO₂e appear as verified ERR figures in the same document
