论文摘要
$ \ rm e^+e^ - $ higgs工厂项目的能源消耗，可以在LHC结束后立即可靠地运行，即三个线性乘客（Clic，在$ \ sqrt {s} = 380 $ gev; and $ \ ilc and $ \ \ rm c^3 $，$ \ rm c^3 $，$ \ rm c^3 $} = 2250 Colliders（CEPC和FCC-EE，以$ \ sqrt {s} = 240 $ GEV运行），这是可以忽略的。因此，未来的希格斯玻色子研究可能会产生重大的环境影响。本说明建议将给定物理性能的碳足迹作为设计优化的顶级量规，并最终选择未来的设施。根据所考虑的Higgs工厂项目，发现了使用2021碳排放量产生的预计的占地面积，并使用2021碳排放进行了评估。
The energy consumption of any of the $\rm e^+e^-$ Higgs factory projects that can credibly operate immediately after the end of LHC, namely 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), will be everything but negligible. Future Higgs boson studies may therefore have a significant environmental impact. This note proposes to include the carbon footprint for a given physics performance as a top-level gauge for the design optimization and, eventually, the choice of the future facility. The projected footprints per Higgs boson produced, evaluated using the 2021 carbon emission of available electricity, are found to vary by a factor 100 depending on the considered Higgs factory project.
