Audit Analysis
The Changtu biomass power plant has VVB-confirmed additionality via an investment test and delivered approximately 105% of its pro-rata ex-ante expectation for the 2019–2022 monitoring period, which is reasonable. However, the project is undermined by contradictory baseline and leakage characterisations across documents, a project-specific baseline with no recorded reassessment, six outstanding corrective actions, and the absence of a buffer pool, LCA, or feedstock sustainability documentation.
Red Flags
- Six corrective actions remain open, including inconsistent weight-meter calibration data and an incorrect Net Calorific Value for biomass type k reported in the monitoring report
- Leakage justification is contradictory: the verification report states it was 'quantified' while the monitoring report states it was 'deemed negligible', yet the deduction is 0% in both cases
- Baseline method is contradictory: the verification report classifies it as project-specific while the monitoring report calls it jurisdictional
- Crediting period end date is missing in the 2023 verification report (stated as open-ended), conflicting with the PDD's stated end date of 2022-04-03
