Audit Analysis

A Gold Standard household biogas project in Assam with VVB-confirmed additionality and no reversal events, but undermined by a project-specific baseline with a non-conformant fNRB calculation, a 239% over-delivery against the pro-rata ex-ante expectation, and extensive documentation errors including contradictory ERR and fNRB values across reports. The project is at the end of its 5-year crediting period with numerous unresolved corrective actions.

Red Flags

  • Verified ERR of 16,539 tCO2e for a 5-month monitoring period represents 239% of the pro-rata ex-ante expectation (6,905 tCO2e), raising over-crediting or calculation-error concerns
  • fNRB value contradicts between the verification report (91) and the monitoring report (0.909), and the calculation was found non-conformant to TOOL30 version 3, requiring reassessment at crediting-period renewal
  • 30+ corrective actions remain open, including removal of 3 damaged non-repairable plants, PDD errors (wrong GS ID, missing location map, inconsistent plant count of 5,000 vs 5,300), and missing grievance mechanism description
