BBMG Cement WHR for 10.5 MW power generation project in Beijing

Audit Analysis

A CDM waste-heat-recovery cement project in Beijing with VVB-confirmed additionality, but undermined by multiple material findings at validation (outdated grid emission factor, excluded captive power plant, unclear barrier analysis) and a ~50% discrepancy in claimed emission reductions between two monitoring reports. The project's integrity is further weakened by contradictory baseline and leakage characterisations across documents, leaving meaningful over-crediting risk unresolved.

Project Description

Red Flags

• ⚠Claimed emission reductions differ by roughly 50% between the 2011 and 2012 monitoring reports (50,431 vs 75,730 tCO2e), with no clear explanation in the extracted record
• ⚠Grid emission factor sourced from 2006 data was flagged by the VVB as not calculated conservatively, and a corrective action required recalculation with the latest data
• ⚠A captive power plant was initially excluded from the project boundary and baseline, requiring a corrective action to include it
• ⚠Leakage justification is contradictory: the 2011 monitoring report states leakage was 'not addressed' while the 2012 report claims it was 'quantified', yet the deduction remains 0%
