The tensions between the values of Hubble constant obtained from the early and the late Universe could be eliminated if we use the ΛWDM cosmological model with dark energy, baryonic matter and warm dark matter (WDM) with characteristic velocities about 16 % of the speed of light. A pressure of WDM is equal to its energy density multiplied by factor 0.009.

Key words
Dark matter, Hubble constant
