  The free scalar field is only conformally invariant when non-minimally
coupled to gravity. In flat space this amounts to amending, or improving, the
energy momentum tensor. A no-go theorem prohibits the improvement for Goldstone
bosons, originating from global internal spontaneous symmetry breaking. It is
shown that the no-go theorem can be circumvented in the presence of a dilaton.
The latter is a (pseudo) Goldstone boson originating from spontaneous conformal
symmetry breaking in a theory with an infrared fixed point. Specifically, the
tracelessness of the energy momentum tensor is demonstrated for a generic
$d$-dimensional curved space. Additionally, the Goldstone gravitational form
factors are shown to obey conformality constraints in the soft limit. The
crucial point is that the remainder term of the soft theorem is non-zero due to
the presence of the dilaton pole. For Goldstone systems with a trivial infrared
fixed point the leading order analysis of this paper ought to be sufficient.
Loop effects govern the improvement term outside the fixed point and are
scheme-dependent as briefly discussed towards the end of the paper.
