Hainan Nanzhonghe IV Small-Scale Hydropower Project

Audit Analysis

A small-scale CDM hydropower project in Hainan, China, with a standard jurisdictional baseline and VVB-confirmed investment additionality, but significant data gaps including no monitoring reports, a seven-fold discrepancy in claimed emissions reductions between the PDD and validation report, and no buffer pool. The project's crediting period (2013–2019) has expired, and the low extraction confidence across seven documents limits the reliability of the available evidence.

Project Description

Red Flags

• ⚠Seven-fold discrepancy in total claimed emissions reductions: the PDD (Sep 2012) states 85,449 tCO₂e while the validation report (Oct 2012) states 12,207 tCO₂e — the ratio of exactly 7× matches the crediting period length, suggesting one figure is annual and the other is the period total, but both are labelled 'total' in their respective documents
• ⚠No buffer pool or permanence mechanism is documented, and no reversal events data is available to confirm the absence of reversals
• ⚠Twelve corrective actions and material findings were raised during validation, including inconsistent input values between the PDD and the Preliminary Design Report, and missing Letters of Approval from both the Chinese and UK DNAs
• ⚠No monitoring reports or verified emissions reduction figures are available in the extracted record, making it impossible to confirm actual delivery against the claimed baseline
