Henan Nanyang Fangcheng Wind Farm Project

Audit Analysis

A CDM wind farm project (CDM-2829) in Henan, China, displacing grid electricity under ACM0002 v7. Additionality was confirmed by TÜV Rheinland via a combined test, and the project type carries inherently low permanence risk. However, 13 corrective actions were raised at validation, multiple inter-document contradictions exist (baseline method, additionality test type, crediting period dates), and the verified ERR for a 3-month window appears disproportionately high relative to the lifetime estimate, warranting caution.

Project Description

Red Flags

• ⚠13 corrective actions (CAR01–CAR13) were raised during validation, including missing Letters of Approval, inconsistent site distances, outdated emission factors, and an unjustified renewable-energy alternative — all resolved but indicating weak initial documentation quality
• ⚠Verified ERR of 10,656 tCO2 for a 3-month monitoring period is approximately 7.4× the pro-rata expectation derived from the 40,152 tCO2 lifetime estimate over 84 months, raising questions about the accuracy of the ex-ante estimate or the monitoring calculation
• ⚠Baseline method is described as 'project-specific' in the 2012 monitoring report but 'jurisdictional' in the 2009 validation report, creating ambiguity about the baseline construction
• ⚠Grid emission factor of 1.1377 tCO2/MWh is from 2008 and was flagged in CAR06 for needing update with more recent data
