We investigate the classical and semiclassical features of generic 2D,
matter-coupled, dilaton gravity theories. In particular, we show that the mass,
the temperature and the flux of Hawking radiation associated with 2D black
holes are invariant under dilaton-dependent Weyl rescalings of the metric. The
relationship between quantum anomalies and Hawking radiation is discussed.
