  The paper presents a general geometric approach to energy-momentum tensors in
Lagrangian field theories, based on a Hilbert-type definition. The approach is
consistent with the ones defining energy-momentum tensors in terms of
hypermomentum maps given by the diffeomorphism invariance of the Lagrangian -
and, in a sense, complementary to these, with the advantage of an increased
simplicity of proofs and also, opening up new insights into the topic. A
special attention is paid to the particular cases of metric and metric-affine
theories.
