Household biogas project in Xintian, Ningyuan, Jianghua and Lanshan counties of Yongzhou City, Hunan Province

Audit Analysis

A CDM household biogas project in Hunan Province with VVB-confirmed additionality (combined test by DNV), but undermined by a 10× discrepancy in the validated emission reduction figure between the PDD and validation report, two corrective action requests at validation, a project-specific modeled baseline with no buffer pool, and a 0% leakage deduction whose justification is inconsistent across documents. The project lacks any post-validation monitoring data, and the low extraction confidence further limits assurance.

Project Description

Red Flags

• ⚠10× discrepancy in total emission reductions: the PDD (2011-03-31) states 527,381 tCO₂e while the validation report (2011-04-04) states 52,738 tCO₂e — a factor-of-ten difference that cannot be reconciled without the underlying calculation sheets
• ⚠Two Corrective Action Requests at validation: the project participant failed to demonstrate compliance with AMS-III.R requirement 4(b) on methane destruction and with AMS-I.C Paragraph 27 on baseline emissions
• ⚠Leakage justification is contradictory: the validation report states leakage is 'deemed negligible' while an appendix describes it as 'quantified', yet the deduction is 0% in both cases
• ⚠No monitoring reports or post-validation verification data found in the extracted record
