  In the literature one often finds the claim that there is no such thing as an
energy-momentum tensor for the gravitational field, and consequently, that the
total energy-momentum conservation can only be defined in terms of a
gravitational energy-momentum pseudo-tensor. Nevertheless, by relaxing the
assumption that gravitational energy-momentum tensor should only depend on
first derivatives of the metric, the Einstein equation leads to a trivial
result that gravitational energy-momentum tensor is essentially the Einstein
tensor. We discuss various peculiarities of such a definition of
energy-momentum are argue that all these peculiarities have a sensible physical
interpretation.
