We show that the Planck mass scale can be generated from conformal gravity in
the Weyl conformal geometry via the Coleman-Weinberg mechanism of dimensional transmutation
where quantum corrections stemming from the gravitational field and the Weyl gauge field trigger the
symmetry breakdown of a local Weyl symmetry. It is also shown that the vacuum expectation value of a scalar field
is transmitted to a sector of the standard model through a potential involving the scale invariant
part and the contribution from the Coleman-Weinberg mechanism, thereby generating the electroweak
