Hebei Handan Damingchang Biogas Recovery and Utilization Project

Audit Analysis
A VCS-registered biogas recovery project in China using the well-established AMS-III.D methodology, with VVB-confirmed additionality and a grievance mechanism in place. However, the project-specific modeled baseline, absence of a stated buffer pool, two inter-document contradictions, and several missing monitoring parameters (carbon content, usage rate, end-use tracking) limit confidence in the credit's robustness. The material findings are minor documentation issues, but the overall evidence base is incomplete.
Red Flags
- Contradiction between the validation report (regulatory additionality test) and the PDD (barrier test) — the two documents describe different additionality pathways
- Carbon content of biogas, usage rate (assumed and verified), and end-use tracking are all absent from the extracted record
- Original survey questionnaires from local residents were not included in the evidence documentation (material finding)
Credit Vintages
No issuances recorded on the registry.
Risk Indicators
VVB-confirmed regulatory test
biogas reversal risk low but unquantified
0% deduction, deemed negligible; justification thin
Project-specific modeled baseline; no reassessment date
FPIC conducted, grievance mechanism present
CORSIA and CCP status not stated in available documents
