CBG Plant at Sainsons

Audit Analysis

The CBG Plant at Sainsons is a VCS-registered biogas project with a solid additionality case (investment test confirmed by the VVB) and a quantified 1.25% leakage deduction, but it is undermined by significant data gaps: no life-cycle assessment, no feedstock sustainability evidence, no carbon-content testing, and no monitoring-period data despite the project having been operational since April 2022. Five contradictions between the PDD and the validation report—covering FPIC, baseline characterisation, leakage, benefit-sharing, and leakage justification—raise concerns about the reliability of the underlying documentation.

Project Description

Red Flags

• ⚠Five contradictions between the PDD (Nov 2023 / Sep 2024) and the validation report (Oct 2024) on FPIC, baseline type, leakage deduction, benefit-sharing, and leakage justification indicate inconsistent project documentation
• ⚠No life-cycle assessment, feedstock sustainability data, or carbon-content testing found in any available document—critical gaps for a biogas project
• ⚠No monitoring-period data or usage-rate verification despite the project having been operational since April 2022
• ⚠Nine clarification requests and four corrective-action requests were raised during validation, suggesting material documentation deficiencies that had to be remediated
• ⚠Minimum extraction confidence is rated low, meaning at least one key document was poorly readable
