On August 1, 2021, Professor Wei Yiming, director of Center for Energy and Environmental Policy Research, led teachers and students of the center to conduct an in-depth survey on the carbon emission management and carbon neutralization scheme of the Beijing 2022 Olympic and Paralympic Winter Games in the National Speed Skating Oval. They made a field visit to the National Speed Skating Oval to understand the venue design concept, architectural structure, carbon dioxide ice making technology and sustainable development plan. They also had a discussion with Wu Xiaonan, chairman and Party secretary of Beijing National Speed Skating Company, Zhu Jingming, deputy general manager, Wang Huijun, executive deputy general manager of Beijing Green Exchange and other responsible comrades. The two sides had in-depth discussions on key issues such as the collection and accounting of carbon emission data of event activities, demonstration and application of zero-carbon buildings, carbon inclusion and carbon neutral scheme formulation of events, exchanged views and put forward relevant suggestions on further promoting the sustainable development of National Speed Skating Oval after the competition and building carbon neutral demonstration district.

   The National Speed Skating Oval is the only newly built ice competition venue for the Beijing 2022 Olympic and Paralympic Winter Games. It will undertake the speed skating competitions and training during the Olympics Winter Games. The construction area of the speed skating hall is about 126,000 square meters. The green and sustainable concept has been practiced during the whole process of design, construction and operation, and it has been awarded the three-star green building rating. The roof adopts 198 meters ×124 meters of the world's largest span orthogonal bidirectional single-layer saddle-shaped roof cable net, and the amount of steel used is one fourth of the traditional steel structure. Equipped with intelligent energy management system, the building is the world's first winter Olympics speed skating stadium with carbon dioxide transcritical direct cooling. After the Beijing 2022 Olympic and Paralympic Winter Games, the National Speed Skating Oval will become a comprehensive Stadium integrating ‘sports events, mass fitness, cultural leisure, exhibition and social welfare’.
