We present an update about our program for the non perturbative renormalization of the energy momentum tensor. Our strategy is based on probing suitable lattice Ward identities with observables computed along the gradient flow. This set of identities exhibits many interesting qualities, resulting from the UV finiteness of flowed composite operators, and can be used to measure the renormalization constants of the energy momentum tensor. We apply this method for a SU(3) Yang-Mills theory on the lattice, and report our numerical results.
