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.

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.
