Analysis

The Oeste de Caucaia Landfill Project is a registered VCS biogas capture activity with VVB-confirmed additionality and a recently reassessed baseline, but it is undermined by a significant grid emission factor discrepancy (0.1363 vs 0.3231), 18 material findings including inconsistent ERRs and a missing double-counting justification, a thin 0% leakage rationale, and no stated buffer pool. The project's data quality and internal consistency raise meaningful concerns about the robustness of its claimed reductions.

Eligibility & market

What can you claim with this credit?

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

  • Airlines (CORSIA)

    Not checked yet

    This registry publishes CORSIA labels, but CarbonMeld has not read this project's credit records yet: we cannot say whether its credits carry one. Check on 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 · ICVCM table read on 4 Oct 2026

    Covers: the methodology (every project using it), not this project's credits

  • Removal or reduction

    Emission reduction or avoidance

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

    Source: project sector

    Covers: the project type, not a label on individual credits

  • 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.
