Abstract	The Extreme Energy Events (EEE) experiment, a joint project of the Centro Fermi and INFN Italian national research institutes, has a dual purpose: a scientific research program for measurements of the cosmic rays flux at ground level and an intense outreach and educational program with an active contribution of students and teachers in the construction and operation of the detectors in High Schools. The network counts 60 tracking detectors, each made by three Multigap Resistive Plate Chambers (MRPC), operated so far with a gas mixture composed by 98% C$_2$H$_2$F$_4$ and 2% SF$_6$. Given its high Global Warming Potential (GWP), the collaboration, since few years, started a R&D; on alternative mixtures environmentally sustainable. Latest results on a C$_3$H$_2$F$_4$ + He eco-friendly mixture are here presented.
