Analysis

This large-scale Gold Standard biogas PoA (240,000+ rural households in Sichuan) has verified additionality and a recently reassessed project-specific baseline, but is undermined by an extensive catalogue of MRV calculation errors, missing data, and contradictions across verification and monitoring reports. The volume of corrective actions—spanning incorrect baseline and project emission calculations, double application of uncertainty factors, and missing QA/QC documentation—raises serious concerns about the reliability of the verified emission reductions. Key parameters such as FNRB, buffer pool, CORSIA eligibility, and CCP status are absent from the available record.

Eligibility & market

What can you claim with this credit?

Four checks buyers ask about, from the registry and the Integrity Council (ICVCM).

  • Airlines (CORSIA)

  • Integrity label (ICVCM CCP)

    Methodology not approved by ICVCMAMS-I.I

    The Integrity Council assessed this methodology as not meeting the Core Carbon Principles.

  • Removal or reduction

    Emission reduction or avoidance

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

  • 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.
