Methane Recovery Project Princepeel Wilbertoord, North Brabant, The Netherlands

Audit Analysis

A VCS-registered methane recovery project in the Netherlands with a confirmed barrier additionality test and an avoidance-based design that eliminates reversal risk. However, the verification report (December 2024) lists ten material findings and nineteen corrective actions, including calculation errors in thermal energy and transportation emissions, an unmeasured biogas production pathway, and an increase in manure quantities beyond the PDD baseline. The 0.5 conservativity factor partially offsets these concerns, but the project-specific modeled baseline and a 0% leakage deduction with only a 'deemed negligible' justification leave moderate over-crediting risk.

Project Description

Red Flags

• ⚠Nineteen corrective actions required by the VVB, including incorrect thermal energy calculation for heat meter 6 and use of average rather than weighted-average transportation distance for manure haulage (2019–2021)
• ⚠Biogas production is calculated from electricity output rather than measured directly, and the 2010 calibration report for the gas analyzer is missing
• ⚠Manure quantities in the monitoring period exceed those stated in the PDD, raising the question of whether the baseline still accurately represents the project's operational envelope
• ⚠Leakage deduction is 0% with only a 'deemed negligible' justification, which is thin for a methane-recovery project where displaced gas could migrate to other sinks
• ⚠Additionality test type differs between the PDD (regulatory surplus, 2021) and the VVB verification report (barrier, 2024), creating ambiguity about which test was actually applied
