The thermal conductivity of a trapped Bose condensed gas is calculated by using the Kubo formula approach. By evaluating the appropriate self-energies of the system the thermal relaxation time is calculated. Below the Bose-Einstein condensation temperature in addition to the relaxation time due to c
