I will discuss the computation of the homology Hirzebruch
characteristic classes of (possibly singular) toric varieties. I will
present two different perspectives for the computation of these
characteristic classes. First, by taking advantage of the torus-orbit
decomposition and the motivic properties of the homology Hirzebruch
classes, we express the latter in terms of the (dual) Todd classes of
closures of orbits. The obtained formula is then applied to weighted
lattice point counting in lattice polytopes. Secondly, in the case of
