Audit Analysis

Alden Forest (Crowley Oaks) is a 40-year urban tree preservation project under the CFC standard with a VVB-confirmed combined additionality test, a substantial 18.3% quantified leakage deduction, and a 10% buffer pool. The primary concerns are the project-specific baseline, the full lifetime credit (7,709 tCO₂e) verified in the first 3-year monitoring period, and several MRV details (FNRB method, usage monitoring) not stated in the available documents. Material findings regarding a project-area discrepancy were identified and corrected by the operator.

Red Flags

  • Full lifetime credit of 7,709 tCO₂e was verified in the first 3-year monitoring period out of a 40-year crediting period, meaning 100% of the ex-ante lifetime estimate was issued in the first period (13.3× the pro-rata expectation of ~578 tCO₂e for 3/40 of the period).
  • Project-specific baseline with no stated reassessment date; the verification report does not confirm when the baseline was last validated.
  • Material finding: 8.64 acres and 17 plots of excess area in the operator's project boundary versus the DRG sampling design, requiring updates to six project documents.
