Analysis

The Two Fiets Digester is a California livestock biogas project with VVB-confirmed additionality, but the 2025 verification report issued a Modified Opinion due to extensive QA/QC failures including methane analyzer calibration gaps, uncorrected data gaps (Feb–Jul 2023), and a missing project-specific monitoring plan. The identical claimed and verified ERR of 14,335 tCO₂e, combined with CORSIA eligibility and an unquantified 'negligible' leakage claim, raises meaningful over-crediting and double-claiming concerns.
