Here, we explore polarized heavy quarkonium production using the color evaporation model at leading order. We present the polarized to total yield ratio as a function of center of mass energy and rapidity in p+p collisions. At energies far above the Q¯Q production threshold, we find charmonium and bottomonium production to be longitudinally polarized (J_z = 0). The quarkonium states are also longitudinally polarized at central rapidity, becoming transversely polarized (J_z = ±1) at the most forward rapidities.
