Issaquah Forest Carbon Offsets
#150of 345 in United States#51of 59 in City Forest Credits (CFC)
Audit Analysis
The Issaquah urban forest preservation project has a VVB-confirmed additionality assessment and a 10% buffer pool, but is undermined by a reported windstorm reversal event affecting 5% of the project area, a missing quantitative leakage deduction, and the absence of FPIC, a grievance mechanism, and independently verified storage. The project-specific baseline and several unaddressed MRV elements (FNRB, usage monitoring) limit confidence in the credit claims.
Red Flags
- Windstorm event (Nov 2024) caused tree failure on 5% of project area, losing stored carbon stock — a material reversal risk in a 40-year permanence claim
- Leakage justification is labelled 'quantified' in the verification report but no deduction percentage is stated in any available document
- No FPIC conducted and no grievance mechanism in place, despite the project affecting a public park area
- Three contradictions across documents (benefit sharing, safeguards, reversal events) reduce confidence in the documentation record
