Heishan LN1 Household Biogas Project in Jinzhou, Liaoning Province

Audit Analysis

A CDM household biogas project (13,104 households) with VVB-confirmed additionality but significant documentation gaps: no monitoring reports are available, the leakage treatment is contradictory across documents, and the validation report recorded ten material findings requiring corrective action. The project's methane-avoidance nature limits permanence risk, but the absence of verified emission data and the low extraction confidence prevent a confident assessment of actual delivery.

Project Description

Red Flags

• ⚠Ten material findings at validation (insufficient household evidence, missing digger/stove specs, unverified baseline coal use, flawed additionality citation, missing Annex I approval letter) indicate a weak initial submission that required substantial remediation
• ⚠Leakage justification is contradictory: the validation report states 'deemed negligible' while an appendix references a 'quantified' assessment, and the final deduction is 0% with no supporting survey data
• ⚠No monitoring reports or verified ERR figures are available in the extracted record, making it impossible to confirm whether the 362,980 tCO₂e lifetime claim was actually delivered
• ⚠Low extraction confidence across the document set means key data may be missing or misread
