The analysis of the correlation between the thermal pressure and the isochoric thermal conductivity of solid CO$_2$ has been carried out. The temperature dependences of the thermal pressure and the isochoric thermal conductivity for samples with various molar volumes have been obtained. The isothermal pressure dependences of the thermal conductivity of solid CO$_2$ have been calculated. The form of the temperature dependence of the isochoric thermal conductivity taking the thermal pressure into account has been revealed. Behaviour of the isochoric thermal conductivity is explained by phonon-phonon interaction and additional influenc of the thermal pressure.
