Electric dipole moments are extremely sensitive probes for additional sources of CP violation in new physics models. We discuss their model-independent extraction from experimental data with the electron EDM as an example, taking the recent measurement with ThO molecules into account. Since recently models including new CP-violating phases have been discussed widely, we revisit the available constraints in the presence of mechanisms which are typically invoked to evade flavour-changing neutral currents. Again carefully assessing the necessary calculations on the hadronic, nuclear and atomic/molecular level, we discuss the resulting bounds in the context of two-Higgs-doublet models, highlighting the interplay with flavour physics.
