Analysis

The Spartanburg County Landfill Gas Combustion Project has a fundamentally sound design with VVB-confirmed additionality, inherent permanence (methane destruction), and a reasonable zero-leakage position. However, the project is burdened by an extensive catalogue of data-quality findings, calibration lapses, and calculation errors spanning multiple monitoring periods, and the low extraction confidence in the underlying documents limits assurance. The project-specific baseline and ambiguous ERR reporting basis introduce moderate over-crediting risk.

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.

  • Removal or reduction

    Emission reduction or avoidance

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

    Source: project sector

  • Paris Agreement (Article 6)

    No Article 6 authorization

    No corresponding adjustment: the host country can also count this reduction towards its own target.

    Source: registry label

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.
