Hennepin Forest Carbon Offsets

Audit Analysis

The Hennepin County urban tree planting project presents a well-structured additionality case with a VVB-verified combined test and a jurisdictional baseline, supported by a 26-year legal permanence obligation and no reported reversals. However, the absence of a quantified leakage deduction, the use of an individual rather than an institutional VVB, and a crediting-period discrepancy between the validation and verification reports introduce moderate uncertainty. The project delivered roughly 88–106% of its pro-rata ex-ante expectation for the first monitoring period, indicating reasonable claim calibration.

Project Description

Red Flags

• ⚠Leakage deduction is not quantified and no justification is provided in any available document, despite the project type (urban tree planting) where displacement of existing canopy or alternative land use could theoretically occur.
• ⚠The crediting period start date differs between the validation report (2022-11-03) and the verification report (2020-05-04), creating ambiguity about the true project start and the length of the crediting window.
• ⚠The VVB is an individual (Matthew Lee) rather than an accredited verification body, which raises questions about institutional independence and capacity for a 26-year crediting period.
