The leading hadronic effects in electroweak theory derive from vacuum polarization which are non-perturbative hadronic contributions to the running of the gauge couplings, the electromagnetic αem(s) and the SU(2)L coupling α2(s). I will report on my recent package alphaQED, which besides the effective fine structure constant αem(s) also allows for a fairly precise calculation of the SU(2)L gauge coupling α2(s). I will briefly review the role, future requirements and possibilities. Applied together with the Rhad package by Harlander and Steinhauser, the package allows to calculate all SM running couplings as well as running sin2 Θ versions with state-of-the-art accuracy.
