Guohua Chenbaerhu Qi Phase I 49.5MW Wind Farm Project

Audit Analysis

A 49.5 MW CDM wind farm in China with VVB-confirmed additionality and a standard grid-emission-factor baseline, but the project delivered only about 17% of its pro-rata expected emissions reductions in the first monitoring period, raising significant over-crediting concerns. Four inter-document contradictions (leakage justification, ERR figures, baseline method, crediting period) and 14 material findings—including missing DNA approval letters—undermine confidence in the project's data integrity.

Project Description

Red Flags

• ⚠Verified ERR of 45,270 tCO₂e for the first monitoring period is only ~17% of the pro-rata expectation (~262,000 tCO₂e) derived from the PDD's lifetime claim of 831,454 tCO₂e over 7 years, indicating a major under-delivery or over-crediting risk.
• ⚠Four contradictions between the PDD, validation report, and monitoring report (leakage justification, ERR figures, baseline method, crediting period) suggest document management or data reliability issues.
• ⚠14 material findings in the verification report, including missing Letters of Approval from both China's and Sweden's DNAs, and the requirement to remove CDM projects from the common-practice analysis, indicate unresolved compliance gaps.
• ⚠Grid emission factor of 1.1461 tCO₂/MWh is based on 2006 data, which is dated and may overstate the baseline if the grid has decarbonised since then.
