Analysis

The Zinguizapa small hydro project (a CPA within the Guacamaya PoA) presents serious integrity and eligibility concerns: the VVB did not confirm additionality at the verification stage, the verification report records an expired crediting period and a rejected UNFCCC renewal rendering the project ineligible for GS certification, and multiple data inconsistencies (faulty meters, swapped CPA labels, generation-figure errors) undermine confidence in the MRV chain. While the project over-delivered relative to its pro-rata ex-ante expectation and leakage treatment is reasonable for small hydro, the cumulative effect of unverified additionality, contradictory baseline and safeguards reporting, and the eligibility finding makes the credit claims unreliable.

    This registry publishes CORSIA labels, but CarbonMeld has not read this project's credit records yet: we cannot say whether its credits carry one. Check on the registry.

  • Integrity label (ICVCM CCP)

    Methodology not approved by ICVCMAMS-I.D

    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.

    Source: project sector

  • 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.
