The Green IT Benchmark is a tool designed and developped by Club Green IT to enable its members (big companies such as Aperam, Engie, Pôle emploi, Renault, Solocal, etc.) compare their information system environmental footprint and their maturity level concerning Green IT. The benchmark is based on an LCA (screening) model and on a 65 Green IT best practices repository and an evaluation system. This tool has been used for years by dozens of national and international companies and in partnership with WWF France, Cigref, CDDD, etc.
