I will discuss the importance of the resummation of threshold logarithms (arising from soft gluon emissions) for Higgs production in gluon fusion at the LHC. I will show that threshold resummation is actually expected to be relevant, even if the process is very far from threshold. We will see that this is mainly due to the shape of the gluon PDF at small-x. I will therefore introduce the resummation of small-x logarithms (arising from hard gluon emissions). Finally, I will present a prediction for the NNNLO Higgs cross-section, based on the known small- and large-z behaviours.
