Analysis

The IdleAir truck-stop electrification project has VVB-confirmed additionality and a verified ERR of 282,053 tCO₂e, but the verification process surfaced multiple material calculation errors (incorrect weighted averages, misapplied eGRID subregions, credits claimed outside the crediting period) that required corrective action. The project-specific modeled baseline, thin leakage justification, and absence of several transparency data points (FNRB, usage rates, grid emission factor value) limit confidence in the credit quantity.

Evidence

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)

    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: methodology

  • 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.
