Audit Analysis
The Lake Charlotte Nature Preserve tree preservation project under the City Forest Credits standard has a VVB-verified combined additionality test and a quantified 18.3% leakage deduction, but carries a material permanence risk from emerald ash borer mortality and a project-specific baseline with no stated reassessment cadence. The verified ERR equals the full lifetime ex-ante estimate for a 3-year monitoring window, which is structurally consistent with one-time tree-preservation issuance but warrants scrutiny. Documentation is adequate in breadth (six documents) but medium in extraction confidence, with several key MRV parameters left unstated.
Red Flags
- Emerald ash borer causing elevated mortality in scattered ash trees, with corrective treatment still pending (verification report, 2023-04-04)
- Reversal events described as 'not addressed' in the verification report, contradicting the validation report's 'none reported' — the more cautious reading is privileged
- Project-specific baseline with no stated last-reassessment date; reassessment cadence under CFC rules not confirmed in available documents
- Verified ERR (36,265 tCO₂e) equals the full 40-year lifetime ex-ante estimate for a 3-year monitoring period, representing 13.3× the pro-rata expectation
