Heilongjiang Bayan Biomass Cogeneration Project

Audit Analysis

A CDM biomass cogeneration project in China with VVB-confirmed additionality but a troubling record of 14 material findings involving fundamental calculation errors (dry vs. wet basis, missing data, non-conservative grid EF). The verified ERR of 172,097 represents only about 13% of the 1,305,842 claimed in the monitoring report, raising serious over-crediting concerns. The project-specific baseline, 2008 grid emission factor, and weak leakage justification further erode confidence in the credit quality.

Project Description

Red Flags

• ⚠Verified ERR (172,097) is only ~13% of the claimed ERR (1,305,842) in the monitoring report, indicating a massive over-claim or significant VVB reduction
• ⚠14 material findings in the validation report, including fundamental dry-vs-wet-basis calculation errors for biomass, missing fossil fuel consumption data, and a non-conservative grid emission factor
• ⚠Grid emission factor of 0.90973 tCO2/MWh is from 2008, over a decade before the monitoring period began in 2013
• ⚠Leakage deduction of 0% justified only as 'deemed negligible' with a contradictory appendix suggesting quantification was attempted
• ⚠PDD (Dec 2012) post-dates the validation report (Jul 2012) and shows additionality_verified_by_vvb as false, contradicting the VVB's own assessment
