Henan Yinge Industrial Investment Corporation Wastewater Treatment and Methane Recovery Project

Audit Analysis

A CDM methane-recovery project from wastewater treatment with a VVB-verified investment additionality test and a measured baseline, but undermined by an unaddressed leakage deduction, a baseline methodology contradiction between the PDD and validation report, and a substantial list of PDD corrections. The project delivered approximately 99% of its pro-rata expected reductions for the monitored period, but key transparency data (verified ERR, FNRB, usage monitoring) are absent from the extracted record.

Project Description

Red Flags

• ⚠Leakage deduction of 0% with the later monitoring report (Aug 2013) stating leakage was 'not addressed,' contradicting the earlier monitoring report (Jun 2012) which indicated it was quantified
• ⚠Baseline methodology contradiction: the validation report (Nov 2010) describes a measured baseline, while the PDD (Mar 2013) describes a modeled baseline
• ⚠No buffer pool or reversal-risk mitigation documented for a 10-year crediting period
• ⚠17 material findings and 13 corrective actions identified during validation, including incorrect installed capacity, missing component parameters, and expired methodology versions
• ⚠Total verified ERR figure is not present in the extracted record, preventing independent cross-check of claimed reductions
