Analysis

A long-running Dutch methane recovery project with VVB-confirmed additionality and a 0.5 conservativity factor, but undermined by five material findings that rely on estimation rather than direct measurement, a 0% leakage deduction that is difficult to justify for a biogas project, and eleven contradictions across its document set. The project delivered essentially 100% of its claimed reductions for the 2022 monitoring period, but the sharp drop from 58,034 tCO₂e in the prior period to 15,201 tCO₂e raises questions about the stability and reliability of the underlying data.

    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 credit type

    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.

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.
