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.
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.
