Winter Olympics: China showcases low-carbon tech for 'green' Games

The Beijing Winter Olympics Committee said in a pre-Games report in January that about 158,300 tonnes of emissions have been saved via deployment of low-carbon energy and venues

From natural carbon dioxide refrigeration at ice rinks to 100% renewables-powered venues, China is striving to run a "green" Olympics to showcase its leadership in climate-friendly tech and counter concerns about the lack of natural snow at its venues.

President Xi Jinping has pledged China, the world's biggest polluter, will reduce its total carbon emissions from 2030 and be a global leader in fighting climate change.

"(The Chinese) want sustainability to be the heart of how they prepare and host the Games," Marie Sallois, Director of Corporate and Sustainable Development at the International Olympics Committee, told Reuters.
