We analyze the kinematics of disk planetary nebulae (PNe) to derive the formal Galactic center distance, R0, for the catalogues of PNe distances by Acker (1978), Cahn et al. (1992), Phillips (2004), and Stanghellini et al. (2008). These distance scales are renormalized to obtain the correct value of R0 =7.9 kpc evaluated from many original estimates (Nikiforov 2004). A new catalogue of distances for PNe was created by averaging all individual renormalized distances.
