Sep 17, 2012 at 15:18 comment added Zhaoting Wei @Alexander Thank you for your comment! Yes I think Chern character map may be the answer and there are a lot of interesting theory on it (for example the paper by J. Block and E. Getzler "Equivariant cyclic homology and equivariant differential forms"). I will think more carefully about this.
Sep 11, 2012 at 17:55 comment added Alexander Woo I'm still hoping someone who understands this better than me answers this, but... Yes - there is (at least in some cases) a "Chern map" taking (equivariant) vector bundles to their (equivariant) Chern classes, and this should be the relation you are looking for.
Sep 11, 2012 at 5:46 comment added Zhaoting Wei Thank you for your comments Damian! Yes, as far as I know the localization theorem is true essentially for compact abelian Lie groups.
Sep 11, 2012 at 5:11 comment added Damian Rössler The localization theorem for equivariant K-theory is valid even when $G$ is a finite group. On the other hand, I think (correct me if I am wrong) that the localisation theorem for equivariant cohomology needs $G$ to have positive dimension to have a non-trivial content. This suggests that there is a conceptual difference between them.
