Understanding how star formation was turned off in galaxies over time and how these passive galaxies then evolve is a major focus of galaxy evolution studies. Equally important is uncovering what role environmental processes play. Here we discuss the evolution of the red sequence in galaxy clusters over the past 9.5 Gyr of cosmic time, as revealed by deep YJK imaging with HAWK-I/VLT of a confirmed massive cluster at z=1.62. We use these data to measure the luminosity function (LF) of red sequence galaxies and chart the growth of the passive sequence. We compare the shape of the LF and the total light on the red sequence in the z=1.62 cluster with clusters at 0.4
