About

EcoIndex.fr is an online service initially designed by Frédéric Bordage (GreenIT.fr) and produced by Gwenael Chailleu and Thomas Samain (Nxtweb). After the first version, many volunteers contributed to the evolutions and improvements of this tool that became a collective project open to all.
