Analysis

The Combio biomass energy project has a VVB-confirmed additionality assessment and a reasonable monitoring record, but suffers from significant baseline calculation deviations, a 0% leakage deduction, and no stated buffer pool. Multiple corrective actions in the latest verification report reveal that baseline emissions were not calculated in accordance with the applied methodology and that the efficiency factor deviated from the registered PDD, raising over-crediting concerns. The project is not CORSIA-eligible, which limits dual-channel risk, but the overall methodological robustness is moderate.
