Analysis

The Dubuque Metropolitan Sanitary Landfill project (CAR-785) is a well-structured landfill gas capture project with VVB-confirmed additionality and a measured baseline, but is undermined by two material findings on instrument calibration, an unquantified leakage treatment, and a notable internal contradiction in the verified ERR figures within the same verification report. The project delivers slightly more than claimed for the monitoring period, reducing over-crediting risk, but data reliability concerns temper confidence.

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 approved for some versionsCAR U.S. Landfill Protocol

    The Integrity Council approved some versions of this protocol and not others: check which version the project uses before claiming CCP quality.

    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.
