Analysis

A Thai biogas/wastewater treatment project (VCS-2261) with VVB-confirmed additionality and a recent monitoring period, but undermined by an extensive list of material findings (30+), a significant baseline overestimation (COD inlet 57% lower than ex-ante), GWP compliance errors, and numerous calibration and data-quality issues. The verified emissions reductions (49,663 tCO₂e) represent only about 41% of the pro-rata expectation for the elapsed monitoring period, suggesting the baseline was overly optimistic. Documentation quality is further weakened by low extraction confidence and a large number of corrective actions.
