We present our analysis of the molecular hydrogen in the circumstellar environment of a sample of Herbig Ae/Be stars observed with FUSE. The characteristics of H2 around Herbig Ae and Be stars gives evidence of two mechanisms of excitation. This suggests structural differences between Herbig Ae and Be stars' environments which could be explained by a faster evolution of the latter combined with stronger radiation fields.
