Analysis

A CDM fuel-switching project (fuel oil to natural gas) at a Korean district heating plant with VVB-confirmed additionality and a quantified leakage treatment, but undermined by multiple calculation errors in the PDD, a project-specific baseline that appears to have over-estimated heat demand, and a significant under-delivery of roughly 12% of the pro-rata ex-ante expectation for the latest monitoring period. The project is conservative in its actual credit issuance relative to the ex-ante estimate, which limits over-crediting risk, but the baseline validity and data reliability are weakened by the contradictions and corrective actions identified across documents.
