Guangxi Guigang Food Waste Recycling Project

Audit Analysis

The Guangxi Guigang Food Waste Recycling Project is a VCS-registered anaerobic digestion project (ACM0022 v3.0) with VVB-confirmed additionality and a reasonable non-permanence position for a non-AFOLU biogas facility. However, four contradictions between the PDD and the validation report — spanning the grid emission factor, lifetime ERR, benefit-sharing description, and leakage treatment — introduce meaningful uncertainty into the credit quantity and baseline assumptions. The absence of any monitoring report, FNRB data, and CORSIA/CCP status limits the ability to verify delivery and market-channel integrity.

Project Description

Red Flags

• ⚠Grid emission factor differs by 61% between the PDD (0.7722) and the validation report (0.4801), directly affecting the baseline displacement calculation
• ⚠Lifetime ERR differs by ~23% between the PDD (146,708 tCO₂e) and the validation report (180,772 tCO₂e)
• ⚠Leakage treatment is described as 'quantified' in the PDD but 'deemed negligible' (0% deduction) in the validation report, with no quantified figure in either document
• ⚠No monitoring report, FNRB value, or usage-monitoring method found in the extracted record
• ⚠Benefit-sharing is described in the PDD but the validation report records it as not described
