ECHO2 Holla-Fresh

Audit Analysis

The ECHO2 Holla-Fresh biochar removal project (Puro.earth, Australia) presents a standard 1,000-year permanence claim with a 2.5% buffer pool and no reported reversal events, but the extracted record lacks documented additionality testing, baseline methodology, and leakage treatment. The verified ERR of 492 tCO2e is consistent between claimed and verified figures in the most recent verification report, though an earlier 2020 report cited 672 tCO2e, suggesting a ~25% downward revision. Multiple critical integrity elements are absent from the available documentation, limiting confidence in the project's additionality and baseline robustness.

Project Description

Red Flags

• ⚠No additionality test type or VVB confirmation of additionality found in the extracted record
• ⚠Baseline method and last reassessment date not stated in any available document
• ⚠Leakage deduction and justification entirely absent from the extracted record
• ⚠ERR discrepancy between the 2020 verification report (672 tCO2e) and the 2023 verification report (492 tCO2e) — a 25% reduction that warrants explanation
• ⚠No safeguards, FPIC, or grievance mechanism documentation found
