Abstract Results from studies on transverse polarization in LEP over the past two years are presented. A single beam transverse polarization level of 57{percent} at 45 GeV was reached adopting strategies to compensate depolarizing effects originating in the four experimental solenoids and from orbit perturbations. Beam Energy Calibration was performed by Resonant Depolarization during the 1993 LEP Run for Physics at three different energies centered around the {ital Z} peak. The uncertainty on the beam energy was reduced to about 1 MeV, thus improving the accuracy on the {ital Z}-resonance mass and width with respect to previous results. Successful results obtained at the end of the 1994 LEP Run on polarization with colliding beams are reported and future plans outlined. {copyright} {ital 1995 American Institute of Physics.}
