Audit Analysis
The Hongwang biogas project in Fangcheng County has a VVB-confirmed additionality assessment and a reasonable pro-rata delivery rate (~94% of expectation), but the verification report identified five material findings on MR data quality (calibration errors, swapped meter numbers, missing QA/QC procedures) and required 21 corrective actions. The absence of a stated buffer pool, unquantified leakage percentage, and non-conducted FPIC leave meaningful gaps in permanence, leakage, and safeguards assurance.
Red Flags
- Five material findings in the verification report relate to calibration validity, swapped electricity meter numbers, missing QA/QC procedures, inconsistent calibration information, and unsupported data sources in the monitoring report
- 21 corrective actions were required, spanning data corrections, calculation errors (BEy, PEy, LEy), missing sensitivity analysis, and incomplete stakeholder consultation records
- No buffer pool percentage or permanence mechanism is stated in the available documents for a biogas project with inherent operational reversal risk
- FPIC was not conducted despite the project involving local farming communities in Fangcheng County
