Analysis

The Perennial CMM CMB8-6 Flare Project is a coal mine methane capture project under the ACR standard with a specific CMM methodology, a named VVB, and a clean verification record (no material findings, no corrective actions). However, several foundational elements — baseline method, leakage treatment, and explicit additionality testing — are not documented in the available records, creating meaningful uncertainty about the robustness of the credit claims. The verified ERR matches the claimed figure exactly, and the project is recent with high extraction confidence, but the gaps in baseline and leakage documentation limit confidence in the integrity of the underlying claims.

What can you claim with this credit?

Four checks buyers ask about, from the registry and the Integrity Council (ICVCM).

    Not usable for airlines' CORSIA obligations.

  • Integrity label (ICVCM CCP)

    The Integrity Council has not decided on this methodology yet.

  • 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.
