Analysis

A long-running Thai biogas project (operating since 2009) with a VVB-verified investment additionality test and no reversal events, but undermined by an unaddressed leakage assessment in the most recent verification, multiple instrument calibration gaps, and a significant discrepancy between claimed and verified emission reductions within the same monitoring report. The project's safeguards and grievance mechanisms are well documented, and CORSIA ineligibility eliminates dual-channel risk, but the absence of a stated buffer pool and usage monitoring details leaves meaningful gaps in the MRV chain.

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)

    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.

    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.
