Lattice QCD offers the possibility of computing parton
distributions from first principles, although not in the usual MSbar
factorization scheme. I will present the evolution of non-singlet
parton distribution functions (PDFs) in the short-distance
factorization scheme which notably arises in lattice calculations in
the pseudo-distribution approach. I will provide an assessment of
non-perturbative evolution of PDFs from already published lattice
matrix elements and show how this evolution can be used to reduce the
fluctuation of the lattice data. By highlighting the limitations of
the current computations, I will advocate for the possibility to use
lattice calculations in small volumes.
