Providence Forest Carbon Offsets

Audit Analysis

The Providence urban tree-planting project has a verified combined additionality test, a jurisdictional baseline, and a 5% buffer pool, with no reversal events reported. However, the extracted record contains a material discrepancy between the validation report (777 tCO₂e) and the verification report (311 tCO₂e) for the same ERR fields, and several key parameters—leakage treatment, crediting period, and permanence claim—are absent from the available documents. The project is modest in scale (1,120 trees, ~777 tCO₂e lifetime) and the overall risk profile is moderate but hampered by data gaps.

Project Description

Red Flags

• ⚠ERR figure contradiction: the validation report (2025-09-24) records 777 tCO₂e while the verification report (2025-09-23) records 311 tCO₂e for both total_err_verified and total_err_claimed; the merged record carries 777, which may conflate the ex-ante lifetime estimate with the period-specific verified figure.
• ⚠Leakage deduction and justification are entirely absent from the extracted record, leaving no documented treatment of displacement or substitution effects for an urban forestry project.
• ⚠Crediting period and permanence claim duration are not stated in any available document, making it impossible to assess the temporal scope of the carbon claim.
