Analysis

A long-running Thai wastewater-to-biogas project (operating since 2007, current crediting period 2017–2027) with VVB-confirmed additionality and no reversal events, but constrained by a project-specific modeled baseline, no stated buffer pool, and material findings including a full year of missing data (2022) and equipment deviations. The 2025 verification confirms 34,000 tCO₂e for the 2021–2023 period, matching the project's claim exactly, though the absence of a lifetime ex-ante estimate limits over-crediting assessment.

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.
