Analysis

The Guangxi Longan Biomass Power Project is a VCS-registered biomass displacement project with a VVB-confirmed combined additionality test and no material findings. However, the project-specific baseline, absence of a stated buffer pool, 0% leakage deduction with a shifting justification, and lack of feedstock sustainability assessment introduce moderate over-crediting and permanence risks. Multiple contradictions between the 2020 and 2023 verification reports reduce confidence in data consistency.

Eligibility & market

What can you claim with this credit?

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

  • Airlines (CORSIA)

    Pilot phase only (2021–2023)

    Eligible only for the pilot phase: not usable for the current 2024–2026 phase.

    Source: registry label · read on 1 Nov 2026

    Covers: credits of this project that carry the label on the registry — not every unit or lot

  • Integrity label (ICVCM CCP)

    Methodology not approved by ICVCMACM0006

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

    Source: ICVCM assessment · ICVCM table read on 4 Oct 2026

    Covers: the methodology (every project using it), not this project's credits

  • Removal or reduction

    Emission reduction or avoidance

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

    Source: project sector

    Covers: the project type, not a label on individual credits

  • Paris Agreement (Article 6)

    No Article 6 authorization

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

    Covers: this project's credit records as read on the registry

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.
