Analysis

The Büyükdüz hydroelectric project has a solid additionality case (investment test confirmed by the VVB) and a well-documented monitoring protocol using TEIAS meter data, but is undermined by twelve unresolved assessment findings, a project-specific baseline, and a leakage treatment that the most recent verification report describes as 'not addressed.' The project delivered roughly 79% of its pro-rata ex-ante expectation for the elapsed monitoring period, which is conservative but the documentation gaps and contradictions between the 2021 and 2023 verification reports reduce confidence in the overall credit quality.

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)

    Methodology not approved by ICVCMACM0002

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

    Source: ICVCM assessment

  • 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.
