The study focuses on evaluating the sustainability of Cross-Silo Federated Learning (FL) throughout the entire AI product lifecycle.Cross-Silo FL is a decentralized approach that allows clients to share model updates rather than raw data, enhancing privacy.The energy consumption and costs of model training are comparable between Cross-Silo FL and Centralized Learning.Centralized Learning can result in significant CO2 emissions due to additional data transfer and storage requirements.
