Analysis

Marshall County Flare II is a coal mine methane capture project verified by TÜV SÜD America with a recent 2024 monitoring period, but the extracted record contains significant evidence gaps: no additionality test, baseline method, or leakage treatment was found in the available documents. Two material findings regarding methane analyzer calibration raise moderate measurement-accuracy concerns, though no corrective actions were mandated. The claimed-to-verified ERR ratio of 98.5% is reassuring, but the absence of ex-ante lifetime estimates prevents a full pro-rata over-crediting check.

  • Removal or reduction

    Emission reduction or avoidance

    Prevents or reduces emissions — fits contribution claims, not SBTi neutralisation.
