  Energy-growing electroweak corrections in the Standard Model are potentially
relevant for LHC physics, for Next generation of Linear Colliders (NLCs) and
for ultrahigh energy cosmic rays. I present here the results of recent work in
which electroweak evolution equations (the analogous of DGLAP equations in QCD)
have been derived. The main features of these effects, mainly related to the
fact that the electroweak sector is spontaneously broken, are pointed out.
