Dekang AWMS GHG Mitigation Project in Guizhou Province

Audit Analysis

The Dekang AWMS project in Guizhou is a registered VCS anaerobic digestion project (ACM0010) with VVB-confirmed additionality via an investment test, but suffers from significant documentation contradictions across six fields, an unquantified leakage deduction, and an unaddressed permanence risk. The discrepancy between the PDD's ex-ante estimate (427,200 tCO2e) and the monitoring report's verified figure (537,393 tCO2e) raises over-crediting concerns that cannot be fully resolved from the available data. Overall, the project meets minimum VCS registration requirements but exhibits moderate-to-high data reliability risks.

Project Description

Red Flags

• ⚠Six contradictions between documents, including FPIC (verification report says not conducted; monitoring report says conducted), grievance mechanism, safeguards, and benefit sharing — all resolved in favor of the later verification report (2022-09-01) indicating these were NOT in place
• ⚠PDD ex-ante estimate of 427,200 tCO2e is 20% lower than the 537,393 tCO2e reported in the monitoring report; the basis (lifetime vs. period) is ambiguous, creating over-crediting uncertainty
• ⚠Permanence risk is listed in the verification report table of contents but the specific content was not extractable; no buffer pool percentage is stated and reversal events are marked as not addressed
• ⚠Leakage is described as 'quantified' in the justification field, yet no specific deduction percentage appears in any extracted document
