Highland Park Forest Carbon Offsets

Audit Analysis

The Highland Park urban forest project demonstrates solid additionality (combined test, VVB-confirmed) and a jurisdictional baseline, with a 5% buffer pool and no reversal events over the first monitoring period. However, the complete absence of any leakage quantification or justification is a notable gap for a tree-planting project, and contradictory ERR figures across the validation and verification reports introduce data-reliability concerns. Overall, the project is reasonably structured but carries moderate risk from the leakage omission and documentation inconsistencies.

Project Description

Red Flags

• ⚠Leakage deduction and justification are entirely absent from all extracted documents — a significant gap for an urban tree-planting project where displaced trees or shifted planting elsewhere could generate leakage
• ⚠Contradictory ERR figures: the validation report (2022-10-26) reports 160 tCO₂e while the verification report (2022-10-25) reports 1,604 tCO₂e for both claimed and verified values, creating ambiguity about the actual credit volume
• ⚠Crediting period start dates differ between documents: the verification report states 2019-06-01 to 2045-06-01, while the validation report states 2022-06-23 to 2048-06-23, both spanning 26 years but anchored to different dates
