Analysis

The Santa Marta LFG project is a long-running Gold Standard landfill gas-to-electricity project with VVB-verified additionality, but it is burdened by a serious contradiction over whether gas capture is legally required, an extensive list of calibration and data-quality findings, a 0% leakage deduction with no stated justification, and the absence of a buffer pool. The project delivered roughly 73% of its pro-rata ex-ante expectation for the elapsed monitoring period, which is conservative, yet the underlying data reliability is undermined by repeated metering and reporting errors across multiple verification cycles.

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 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.
