Description

In this talk, we will discuss the studies presented in PRX ENERGY 2, 047001, where the carbon impact of the Cool Copper Collider (C$^3$), a proposed $e^{+}e^{-}$ linear collider operated at 250 and 550 GeV center-of-mass energies, is evaluated. We will introduce several strategies that could be utilized to reduce the power needs for C$^3$ without modifications in the ultimate physics reach. We will also propose a metric to evaluate the carbon costs of Higgs factories, balancing physics output, energy needs, and carbon footprint for both construction and operation, and we will present a comparison of C$^3$ with other Higgs factory proposals – ILC, CLIC, FCC-ee and CEPC – within this framework. We conclude that the compact 8 km footprint and the possibility for cut-and-cover construction make C$^3$ a compelling option for a sustainable Higgs factory. More broadly, the developed methodology serves as a starting point for evaluating and minimizing the environmental impact of future colliders without compromising their physics potential.
