Aimed at identifying solutions for the reuse rock excavated during tunnelling for future CERN colliders, this competition shortlisted four promising proposals.

A recent analysis, comparing the environmental impact of different proposed Higgs factories per physics output, concluded that the FCC-ee is the most sustainable design.

Optimised system designs for power efficiency, high efficiency klystrons, permanent magnets, renewable power… The linear collider projects are working to address power efficiency and reduce the environmental impact of the facilities.

The first test to use a particle accelerator to clean the exhaust gases of a ship took place in Riga in July 2019. The first results are encouraging.
