  Electric dipole moments are extremely sensitive probes for additional sources
of CP violation in new physics models. The multi-scale problem of relating the
high-precision measurements with neutrons, atoms and molecules to fundamental
parameters can be approached model-independently to a large extent; however,
care must be taken to include the uncertainties from especially nuclear and QCD
calculations properly. The resulting bounds on fundamental parameters are
illustrated in the context of Two-Higgs-Doublet models.
