  At high energy the standard model possesses conformal symmetry at the
classical level. This is reflected at the quantum level by relations between
the different beta functions of the model. These relations are known as the
Weyl consistency conditions. We show that it is possible to satisfy them order
by order in perturbation theory, provided that a suitable coupling constant
counting scheme is used. As a direct phenomenological application, we study the
stability of the standard model vacuum at high energies and compare with
previous computations violating the Weyl consistency conditions.
