  • AMS-I.D. - Grid connected renewable electricity generation - 1.0-18.0: does not meet the Core Carbon Principles

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