Analysis

The Perennial CN9-2 AMM Flare Project is a coal mine methane capture project under ACR's Compliance Offset Protocol, but the available documents contain almost no verifiable detail on additionality, baseline, leakage, or MRV. No material findings or corrective actions were reported, and the standardized compliance methodology provides structural guardrails, yet the near-total absence of quantified data makes a robust quality assessment impossible.

  • Integrity label (ICVCM CCP)

    Methodology under ICVCM assessmentACR Capturing and Destroying Methane from Coal

    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)

    Not checked yet

    This registry publishes Article 6 authorizations, but CarbonMeld has not read this project's credit records yet: we cannot say whether any credits are authorized. Check on the registry.

Information only, from public sources. Claim rules (CORSIA, SBTi, EU rules on green claims) change: check them before making a public claim. Since 27 September 2026, EU consumer rules do not allow “climate neutral” product claims based on offsets.
