# Green Proofs for Electrical Vehicles (GP4EV)

The Green Proofs for EVs (GP4EV) system plays a crucial role in ensuring that electric vehicle (EV) charging is green by managing and verifying green certificates for each charging session. All the data sent to workers in this process originates from the Green Proofs application, which transforms this data into operations like issuing, transferring, or retiring certificates.
