Audit Analysis

The Gaïago soil revitalization project is a French cropland carbon removal project verified by DNV Business Assurance France under ISO 14064-2:2019, with a 20% buffer pool and no reported reversal events. The project delivered only about 35% of its pro-rata ex-ante expectation for the elapsed monitoring period, which is conservative but raises questions about the accuracy of the original estimate. Key gaps include unconfirmed VVB verification of additionality, a project-specific baseline without a stated reassessment date, and a contradiction in how leakage is characterised across documents.

Red Flags

  • Leakage justification is contradictory: the PDD (Dec 2025) describes it as 'quantified' while the methodology (Nov 2023) describes it as 'deemed negligible', yet the actual deduction is 0% in both cases
  • Additionality test type is listed as 'combined' but the verification report does not explicitly confirm that the VVB (DNV Business Assurance France) validated the additionality assessment
  • The project delivered only ~35% of the pro-rata ex-ante expectation (4,797 tCO2e verified vs ~13,766 tCO2e expected for the elapsed period), suggesting the lifetime estimate of 17,080 tCO2e may have been overly optimistic
  • CORSIA eligibility and CCP status are not stated in any available document, leaving dual-channel risk unassessed
