Chongqing Fufeng Cement 9MW Waste Heat Recovery for Power Generation Project

Audit Analysis

A CDM waste-heat-recovery project at a cement plant with a VVB-confirmed investment additionality test and a standardised methodology (AMS-III.Q), but undermined by a grid emission factor frozen at a 2008 value, multiple material findings (meter calibration delays, unexplained project-owner change, an additional clinker line), and contradictory ERR and crediting-period figures across monitoring reports. The project is functional but carries moderate over-crediting and documentation-reliability risk.

Project Description

Red Flags

• ⚠Grid emission factor of 0.7707 tCO2/MWh is anchored to 2008 data while the monitoring period covers 2015–2017, risking systematic over-estimation of reductions as China's grid decarbonised over that interval.
• ⚠The 2017 monitoring report records a claimed ERR of 56,857 tCO2e versus 85,013 tCO2e in the 2015 monitoring report — a 33 % drop that is not explained by a change in methodology or baseline.
• ⚠Material findings flag meter-calibration gaps spanning roughly 14 months across two monitoring periods, a project-owner change, and an additional clinker line not reflected in the original PDD, all of which raise questions about the accuracy of the verified figures.
• ⚠The crediting period differs between the validation report (2013-02-01 to 2023-02-01) and the 2017 monitoring report (2012-11-19 to 2022-11-18), creating ambiguity about the true project lifetime.
