  The Noether charge associated to diffeomorphism invariance in teleparallel
gravity is derived. It is shown that the latter yields the ADM mass of an
asymptotically flat spacetime. The black hole entropy is then investigated
based on Wald's prescription that relies on the Noether charge. It is shown
that, like in general relativity, the surface gravity can be factored out from
such a charge. Consequently, the similarity with the first law of
thermodynamics implied by such an approach in general relativity does show up
also in teleparallel gravity. It is found that, based on the expression of the
first law of black hole mechanics, which is preserved in teleparallel gravity,
entropy can thus be extracted from such a Noether charge. The resulting entropy
can very naturally be expressed as a {\it volume integral}, though. As such, it
is shown that the conformal issue that plagues the entropy-area law within
general relativity does not arise in teleparallel gravity based on Wald's
approach. The physics behind these features is discussed.
