This paper deals with the interpretation of the Hartwick rule in the particular Dasgupta-Heal-Solow model with one capital good and one non-renewable resource. It is argued that the rule is more a descriptive property of constant consumption paths than a sustainability indicator. It is shown that investing the rents from the resource use into man-made capital is a necessary condition for an efficient resource depletion but it is not a sufficient condition for sustainability. A sustainable consumption indicator is described to characterize the sustainability of constant consumption paths.
