Beijing Taiyanggong CCGT Trigeneration Project

Audit Analysis

A CDM CCGT trigeneration fuel-switch project with VVB-confirmed additionality and a jurisdictional grid-emission-factor baseline, but undermined by four cross-document contradictions (notably a 7× discrepancy in claimed ERR), six material findings, and the absence of a verification report or verified ERR figure. The project type carries low inherent reversal risk, yet the documentation gaps and data inconsistencies limit confidence in the credit quantity.

Project Description

Red Flags

• ⚠Claimed ERR differs by a factor of ~7 between the validation report (551,468 tCO₂e) and the monitoring report (3,860,276 tCO₂e); the basis for each figure is unexplained in the extracted record
• ⚠Baseline method is described as 'jurisdictional' in the monitoring report but 'project-specific' in the PDD, creating ambiguity about which baseline actually underpins the credit calculation
• ⚠No verification report appears in the evidence document list; only a validation report, PDD, and monitoring report are available, leaving the verified ERR figure entirely absent
• ⚠Six material findings were raised during validation, including missing data sources for coal NCV, incomplete baseline validity presentation, and a methodology reference inconsistency (AM0029 vs ACM0002)
