The Olympic solution to fight global warming is frozen

Jhe world is increasingly focused on sustainability and reducing greenhouse gas emissions, and the Beijing Olympics put sustainability front and center with the 2022 Winter Games. green technology is the carbon dioxide refrigeration system used at four of the venues where the Olympics and Paralympics are taking place, reflecting the focus on sustainability to which China is committed, reports the International Olympic Committee.

Ice rinks have traditionally used hydrofluorocarbons (HFCs), a chemical known for its harmful qualities to the ozone layer and its status as a contributor to climate change at 4,000 times the rate of carbon dioxide. The new CO2 refrigerants will help to significantly reduce the emissions produced by the Olympics, bringing carbon emissions to near zero; an equivalent reduction would be to plant 1.2 million trees.

“The Olympic Games are first and foremost a sporting event, but with their global visibility, they also provide an important platform to showcase sustainable solutions,” said Marie Sallois, IOC Director for Sustainability.

The ‘Ribbon of Ice’, the national speed skating ring and the only new venue built for the Beijing Olympics, will not only use carbon dioxide technology that runs on purified CO2 captured from waste gas but it will also capture the waste heat that the refrigeration process generates. It recycles heat created for ambient stadium heating, hot water for showers, to make and melt ice, and to control indoor temperature and humidity year-round.

The National Speed ​​Skating Oval, Capital Indoor Stadium, Capital Short Track Speed ​​Skating Training Hall and Wukesong Ice Hockey Training Hall will all use the new technology. Carbon dioxide cooling is 1.2 times more efficient than HFC refrigeration and can keep the temperature on the ice at a constant 0.5 degrees Celsius, creating an ice surface that is easier to skate on.
