Analysis

The Mamak Landfill Waste Management Project is a long-running Gold Standard landfill gas capture project with confirmed additionality and measured usage monitoring, but it carries significant operational and documentation concerns. Numerous material findings—including a non-operational gasifier, a digester feeding only two of six expected engines, calculation inconsistencies, and a 16.5% gap between claimed and verified emission reductions—undermine confidence in the integrity and accuracy of reported credits. The absence of a buffer pool, unaddressed reversal risk, and CORSIA eligibility without clear CCP status introduce additional claim-safety concerns.

Eligibility & market

What can you claim with this credit?

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

  • Airlines (CORSIA)

    Stated in the project documents

    The documents claim CORSIA eligibility, but no registry label confirms it: check vintage and authorization.

    Source: project documents (not confirmed by the registry)

  • Integrity label (ICVCM CCP)

    Methodology approved by ICVCMACM0001

    The methodology meets the Core Carbon Principles; this project's credits do not carry the CCP label yet.

    Source: ICVCM assessment

  • Removal or reduction

    Emission reduction or avoidance

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

    Source: registry label

  • Paris Agreement (Article 6)

    Not published

    This registry does not publish Article 6 authorizations.

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.

Being within an ICVCM-approved version range is information only: it does not mean these credits carry the CCP label, which the registry assigns to each issuance.

A version is shown only when the document's own text writes it next to the methodology code. Current versions, status and CCP ranges come from the official pages linked, checked on the date shown.
