Audit Analysis

A Wisconsin forest carbon project under ACR with a 20-year crediting period, strong permanence safeguards (16% buffer pool, 40-year reversal-risk agreement, no reversal events), and a highly conservative 40% leakage deduction. The first monitoring period shows over-delivery relative to the pro-rata ex-ante expectation, but five material findings (calculation errors, documentation gaps) required corrective action, and the project-specific baseline and absence of FPIC temper the overall assessment.

Red Flags

  • Five material findings in the verification report (decay-class inconsistency, bark-ratio error, scale-slip discrepancies, buffer-reduction mismatch, silvicultural description errors) required corrective action before issuance
  • FPIC was not conducted and no grievance mechanism is documented, despite the project being on private forestland in Wisconsin
  • Baseline is project-specific rather than jurisdictional or standardised, increasing sensitivity to local management assumptions
