Audit Analysis

A VCS-registered biogas project from swine manure with VVB-confirmed additionality and a quantified leakage treatment, but significant gaps in permanence safeguards (no buffer pool stated), a project-specific modeled baseline, and a notable discrepancy between the PDD's ex-ante estimate and the verified ERR that raises over-crediting concerns. The project is functional but carries moderate data-reliability risk.

Red Flags

  • The PDD (2022-09-20) states a claimed ERR of 201,850 while the verification report (2022-12-12) reports 336,417 for the same monitoring period — a 67% discrepancy that undermines confidence in the baseline calibration
  • Buffer pool percentage is not stated in any available document, leaving permanence risk unquantified for a project where digester failure could reverse credits
  • Six material findings in the verification report (including missing ER calculation spreadsheets and missing ex-ante/ex-post comparison) were resolved as clarifications only, with no corrective actions required — the underlying data gaps may persist
