Analysis

This ACR coal-mine-methane capture project in West Virginia has a fundamental additionality concern: the verification record confirms that methane capture is legally required at the mine, yet no specific additionality test type or VVB confirmation of additionality is documented in the extracted data. While the verified emissions reductions (116,527 tCO₂e) exceed the claimed figure (107,916 tCO₂e) for the monitoring period—indicating no over-crediting—the absence of a stated baseline method, leakage treatment, and safeguards documentation, combined with low extraction confidence, leaves significant evidence gaps.

  • Removal or reduction

    Emission reduction or avoidance

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

  • Paris Agreement (Article 6)

    No Article 6 authorization

    No corresponding adjustment: the host country can also count this reduction towards its own target.
