Analysis

The Nueva Aldea biomass power plant is a technology-based CDM project with a barrier additionality test and a project-specific baseline, but the verification record is undermined by two material findings (missing monitoring parameters and ER calculation errors) and multiple contradictions across documents, particularly a 2.76× discrepancy in the ex-ante lifetime ERR. The 0% leakage deduction is supported by a quantified justification in the monitoring report, and the project carries no carbon-stock reversal risk given its biomass-energy nature.

    This registry does not publish CORSIA eligibility per project.

  • Integrity label (ICVCM CCP)

    No ICVCM information

    No CCP label and no ICVCM decision found for this project's methodology.

  • Removal or reduction

    Emission reduction or avoidance

    Prevents or reduces emissions — fits contribution claims, not SBTi neutralisation.
