AB  - Entropy production plays a fundamental role in the study of non-equilibriumsystems by offering a quantitative handle on the degree of time-reversalsymmetry breaking. It depends crucially on the degree of freedom considered aswell as on the scale of description. It was hitherto unknown how the entropyproduction at one resolution of the degrees of freedom is related to theentropy production at another resolution. This relationship is of particularrelevance to coarse grained and continuum descriptions of a given phenomenon.In this work, we derive the scaling of the entropy production under iterativecoarse graining on the basis of the correlations of the underlying microscopictransition rates. Our approach unveils a natural criterion to distinguishequilibrium-like and genuinely non-equilibrium macroscopic phenomena based onthe sign of the scaling exponent of the entropy production per mesostate.
