Gearing up for greener, cleaner Winter Olympics

International experts say ice-making system represents giant step forward

Citing the use of eco-friendly and high-efficient refrigerants at multiple venues, international experts have hailed the ice-making system adopted by Beijing 2022 organizers as a game changer for a sustainable future.

A week out from the first sporting action at the Games, Beijing 2022's ice sports program has already secured a place in history as Chinese organizers, guided by international experts, have implemented carbon dioxide as a green, safe and efficient refrigerant in the cooling systems at five competition and training rinks.

It is the first time a CO2-based refrigerant has been used on this scale at the Winter Olympics.
