  A intriguing feature shared by many quantum gravity programs is the dynamical
decrease of the spectral dimension from $D_s = 4$ at macroscopic to $D_s
\approx 2$ at microscopic scales. In this note, we study the impact of this
transition on the energy loss of static, spherically symmetric black holes due
to Hawking radiation. We demonstrate that the decrease in the spectral
dimension renders the luminosity of a black hole finite. While this slightly
increases the life-time of light black holes, we find that this mechanism is
insufficient to generate long-lived black hole remnants. We briefly comment on
the relation of our findings to previous work on this topic.
