Henan Zhumadian Youran Xiping Dairy Farm Biogas Utilization Project

Audit Analysis

A VCS biogas avoidance project with VVB-verified additionality and smart-meter monitoring, but undermined by a significant grid emission factor contradiction (1.3 vs 0.5734 kgCO₂/kWh), a 0% leakage deduction with internally inconsistent justification, and nine material findings that required sixteen corrective actions. The project delivered roughly 106% of its pro-rata ex-ante expectation for the elapsed monitoring period, which is within a reasonable range, but the data reliability issues cast doubt on the precision of the credit quantity.

Project Description

Red Flags

• ⚠Grid emission factor contradiction: the verification report uses 1.3 while the PDD uses 0.5734 (kgCO₂/kWh); if the higher value was applied, electricity-displacement credits could be inflated by more than 100%
• ⚠Leakage deduction of 0% is justified as 'quantified' in one part of the verification report but as 'deemed negligible' in another, creating an internal inconsistency in the same document
• ⚠Nine material findings and sixteen corrective action requests were raised during verification, including insufficient quantification of emission reduction calculations, missing IPCC default justifications, and an inconsistency in the reported GHG reduction value (94,155 vs 91,275 tCO₂e)
• ⚠FNRB value and method are not stated in any available document, leaving a key parameter unverifiable
• ⚠CORSIA eligibility and CCP status are both not stated, leaving dual-channel risk unassessed
