Analysis

The Aurá Landfill Gas Project is a CDM landfill gas capture project in Brazil with VVB-confirmed additionality and a measured project-specific baseline, but it is undermined by inconsistent leakage treatment across monitoring reports, a very short two-month monitoring window, contradictory ERR figures, and the absence of FPIC, a grievance mechanism, or any documented safeguards. The project's integrity is further weakened by an open corrective action on the monitoring plan and a baseline last reassessed in 2005.

  • Integrity label (ICVCM CCP)

    No ICVCM information

    No CCP label and no ICVCM decision found for this project's methodology.

  • Removal or reduction

    Emission reduction or avoidance

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

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.
