The Paris Olympics is going underground to find a way to keep athletes cool at the 2024 Games without air conditioners. Organizers are planning to install a water-cooling system under the Athletes Village like the one that has helped the Louvre Museum cope with the sweltering heat that broke records last year. The plan is in line with the Paris mayor’s resolve to drastically reduce the French capital’s greenhouse gas emissions and make the City of Lights carbon neutral by 2050. Two-time Olympic champion and marathon world record holder Eliud Kipchoge endorsed the Paris sustainability plan. He says “we all need to reduce our carbon.”
