Position in the cycle

Where the Retirement Receipt fits.

Five contract families cover the path from the material to the attribution of the outcome, across four stages. Each record points back to the one before it.

  1. 01

    Record

    The batch of material is verified and enters the network as a permanent record.

  2. 02

    Certification

    The reduction or the recycling is certified under an active methodology, and the credit is issued.

  3. 03

    Purchase

    The credit purchase becomes a public record, tied to the certificates it came from.

  4. 04

    Registration

    The credit leaves circulation and the environmental outcome is attributed for good.
