Description
The energy consumption of an ${\rm e^+e^-}$ Higgs factory in operation will be everything but negligible. Future Higgs boson studies may therefore have a significant environmental impact. We propose ways to estimate the environmental footprint during the operation of all the Higgs factory projects that can credibly operate immediately after the end of LHC, namely the projects for three linear colliders (CLIC, operating at $\sqrt{s} = 380$\,GeV; and ILC and $\rm C^3$, operating at $\sqrt{s} =250$\,GeV) and two circular colliders (CEPC and FCC-ee, operating at $\sqrt{s} =240$\,GeV). The projected carbon footprint varies from single to a hundredfold depending on the Higgs factory considered.
