Abstract The search for sub-GeV dark matter via scattering on electrons has ramped up in the last few years. Like in the case of dark matter scattering on nuclei, electron-recoil-based searches also face an ultimate background in the form of neutrinos. The so-called “neutrino fog” refers to the range of open dark matter parameter space where the background of neutrinos can potentially prevent a conclusive discovery claim of a dark matter signal from being made.
