Audit Analysis
The Middlesex Forest Carbon Offsets project is a 40-year urban tree preservation initiative under the City Forest Credits standard with a VVB-confirmed combined additionality test, a 10% reversal buffer, and no reported reversal events. The project-specific baseline and a ~10% discrepancy between the PDD and verification report ERR figures introduce moderate claim-safety concerns, while several transparency indicators (FNRB, usage monitoring, CORSIA/CCP status) remain unstated in the available documents.
Red Flags
- PDD (Feb 2024) reports a lifetime ERR of 3,907 tCO₂e while the verification report (Apr 2024) reports 3,516 tCO₂e — a ~10% discrepancy resolved in favour of the lower, more conservative verification figure
- Leakage is described as 'quantified' in the verification report but the specific deduction percentage is not stated in any available document
- Baseline is project-specific with no documented reassessment date; the CFC standard's reassessment cadence is not confirmed in the extracted record
