Climate-Friendly Ice Rinks Made Big Debut at Winter Olympics
In addition to what happens on the rink, the ice itself is making history at the 2022 Beijing Winter OlympicsA big change has been set into motion at the 2022 Winter Olympics in Beijing. This year was the first time the Winter Olympics used climate-friendly ice.
Engineers implemented carbon dioxide technology at the ice rink venues, rather than using hydrofluorocarbons, harmful chemicals currently used in the majority of the world's rinks to keep them cold. Hydrofluorocarbons, or HFCs, are used to keep long stretches of ice, like the ones in arenas and skating rinks, cold for long periods of time. HFCs are human-made greenhouse gasses that absorb heat and are used to do things such as keep your refrigerator cold.
But these refrigerants pose environmental problems. In recent years, HFCs have been proven to cause ozone depletion. A single kilogram of an HFC is equal to running a car for six months.,"HFCs are potent greenhouse gasses that can be hundreds to thousands of times more potent than carbon dioxide in contributing to climate change per unit of mass. A recent study concluded that replacing high-GWP HFCs with low-GWP alternatives could avoid 0.1°C of warming by 2050.
