I will discuss the various mechanisms potentially at work in hadroproduction of heavy quarkonia at RHIC, Tevatron and LHC energies in the light of computations of higher-order QCD corrections both in the colour-singlet (CS) and colour-octet (CO) channels. Besides, I will discuss new observables meant to better discriminate between these different mechanisms, including associated production and correlation measurements. On the other hand, I will show how the kinematics specific to the J/psi production matters for the extraction of Cold Nuclear Matter effects, e.g. the shadowing of the gluon distribution in nuclei.
