## Summary

The e-footprint tool, developed by Publicis Sapient and released as open source in 2023, is increasingly used to assess the digital footprint of IT architectures, notably AI workloads. Schneider Electric applied it this year to compare energy management architectures, with one configuration reducing CO2 emissions by more than 40% compared with the initial design. Since June 2026, the tool has been integrated into the GenAI footprint Alliance, used by AXA, Engie, La Poste, La Banque Postale, Accor, FDJ United, Orange, L'Oréal and Renault Group to estimate the environmental impact of AI-generated content. The tool is hosted by Boavizta, a French collective of more than 200 members dedicated to measuring the environmental impact of digital technology.
