ICVCM status

Methodology under ICVCM assessment.

  • AMS-I.C. - Thermal energy production with or without electricity - 1.0-22.0

The CCP label is applied to credits by the registry, issuance by issuance. An approved methodology means credits from projects using it can be eligible; it does not mean every credit carries the label.

What this means

CORSIA programme relevance

Whether the programmes this methodology is used on are approved by ICAO. Programme level only; unit eligibility depends on dates, authorisation and each programme's exclusions.
