This talk discusses Generalized Parton Distributions (GPDs), which encode various types of non-perturbative information relevant to the QCD description of exclusive processes. Results on their Next-to-Leading Order (NLO) QCD evolution are presented. We find that models for the input GPDs based on double distributions require some modification in order to reproduce the available data on deeply virtual Compton scattering.
