The problem of the comological constant appears in a new light in Unimodular
Gravity. In particular, the zero momentum piece of the potential (that is, the constant piece
independent of the matter fields) does not automatically produce a cosmological constant
proportional to it. The aim of this paper is to give some details on a calculation showing
that quantum corrections do not renormalize the classical value of this observable
