Analysis

The Alcoa Landfill Gas Destruction Project is a CAR-registered methane capture and combustion project in Tennessee with VVB-confirmed additionality and a reputable verifier (SCS Global Services). However, the project exhibits notable gaps: no leakage treatment is documented, the baseline is project-specific and modeled without a stated reassessment date, and safeguards (FPIC, grievance mechanism, benefit sharing) are entirely absent. Material misstatements were identified during verification but corrected before final review, and two sets of ERR figures across verification reports present unresolved discrepancies.

Eligibility & market

What can you claim with this credit?

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

  • Airlines (CORSIA)

    No CORSIA label on the registry

    Not usable for airlines' CORSIA obligations.

    Source: registry label

  • Integrity label (ICVCM CCP)

    Methodology approved for some versionsCAR U.S. Landfill Protocol

    The Integrity Council approved some versions of this protocol and not others: check which version the project uses before claiming CCP quality.

    Source: ICVCM assessment

  • Removal or reduction

    Emission reduction or avoidance

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

    Source: project sector

  • Paris Agreement (Article 6)

    No Article 6 authorization

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

    Source: registry label

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.
