  Resistive Plate Chamber detectors are largely used in current High Energy
Physics experiments, typically operated in avalanche mode with large fractions
of Tetrafluoroethane (C2H2F4), a gas recently banned by the European Union due
to its high Global Warming Potential (GWP). An intense R&D activity is ongoing
to improve RPC technology in view of future HEP applications. In the last few
years the RPC EcoGas@GIF++ Collaboration has been putting in place a joint
effort between the ALICE, ATLAS, CMS, LHCb/SHiP and EP-DT Communities to
investigate the performance of present and future RPC generations with
eco-friendly gas mixtures. Detectors with different layout and electronics have
been operated with ecological gas mixtures, with and without irradiation at the
CERN Gamma Irradiation Facility (GIF++). Results of these performance studies
together with plans for an aging test campaign are discussed in this article.
