Spectators at the 2022 Winter Olympics will be encouraged to travel by public transport across the three competition zones - downtown Beijing, its suburban Yanqing district and co-host Zhangjiakou in Hebei province - which have been connected by an electric-powered high-speed railway that began operation in late 2019.

All passenger vehicles used for the Games' official transport service will be powered by renewable energy. New energy vehicle charging facilities have been built at the venues and along roads between Beijing and Zhangjiakou.
