  Resistive Plate Chambers (RPCs) are gaseous detectors widely used in high
energy physics experiments, operating with a gas mixture primarily containing
Tetrafluoroethane (C$_{2}$H$_{2}$F$_{4}$), commonly known as R-134a, which has
a global warming potential (GWP) of 1430. To comply with European regulations
and explore environmentally friendly alternatives, the RPC EcoGas@GIF++
collaboration, involving ALICE, ATLAS, CMS, LHCb/SHiP, and EP-DT communities,
has undertaken intensive R\&D efforts to explore new gas mixtures for RPC
technology.
  A leading alternative under investigation is HFO1234ze, boasting a low GWP of
6 and demonstrating reasonable performance compared to R-134a. Over the past
few years, RPC detectors with slightly different characteristics and
electronics have been studied using HFO and CO$_{2}$-based gas mixtures at the
CERN Gamma Irradiation Facility. An aging test campaign was launched in August
2022, and during the latest test beam in July 2023, all detector systems
underwent evaluation. This contribution will report the results of the aging
studies and the performance evaluations of the detectors with and without
irradiation.
