In this talk, I present the brand new results from the H1 and ZEUS Collaborations on the combination of all previously published inclusive deep inelastic cross sections at HERA for neutral and charged current e^± p scattering for zero beam polarisation and the corresponding parton distributions functions, HERAPDF 2.0, at up to next-to-next-to-leading order (NNLO). The results also include a new precise determination at next-to-leading order (NLO) of the strong coupling constant αs(M2Z)=0.1184± 0.0016 (excluding scale uncertainties) based on a simultaneous fit to the combined inclusive cross section data and jet production data.
