[Beijing Winter Olympics] From venues to transportation, the Beijing Winter Olympics Organizing Committee takes multiple measures to promote the construction of low-carbon Winter Olympics
[Explanation] On May 26, the Beijing Winter Olympics Organizing Committee held a low-carbon Winter Olympics theme press conference to introduce the construction of low-carbon venues, low-carbon energy applications, and clean energy vehicle applications for the Beijing Winter Olympics.
Venue construction and energy supply are important foundations and guarantees for the successful hosting of the Olympic Games, as well as key areas of carbon emission control.
Liu Yumin, Director of the Planning and Construction Department of the Beijing Winter Olympics Organizing Committee, introduced that in order to achieve the goal of low-carbon venues, the Beijing Winter Olympics Organizing Committee made full use of the existing venues to host the games, which not only reduced the carbon emissions of the games, but also laid a foundation for the wide application of multi-projects after the games.了基。 The foundation.

The Beijing Winter Olympics makes full use of the National Aquatics Center, National Stadium, Wukesong Sports Center, Capital Gymnasium and other summer Olympic venues, and applies the latest technological achievements, adapts measures to local conditions, and innovatively proposes "water-to-ice conversion" through transformation. Land ice conversion" to convert these summer Olympic venues into ice venues for the Beijing Winter Olympics.
[Explanation] At the same time, four ice stadiums, including the National Speed Skating Stadium and the Capital Gymnasium, used the carbon dioxide transcritical direct cooling ice-making technology for the first time in the history of the Winter Olympics.
This not only reduces the damage of traditional refrigerants to the ozone layer, but also greatly reduces the energy consumption of the refrigeration system.
[Concurrent] Liu Yumin, Director of the Planning and Construction Department of the Beijing Winter Olympics Organizing Committee
Taking the National Speed Skating Stadium as an example, the use of carbon dioxide refrigerant not only makes the stadium’s carbon emissions close to zero, but also controls the temperature difference of the stadium’s ice surface to within 0.5 degrees Celsius, providing athletes with a better competition venue. Compared with traditional cooling technology, Can effectively increase the effectiveness of 20%.
[Explanation] In order to implement the concept of green Olympics, the Beijing Winter Olympics Organizing Committee will also build a low-carbon transportation system during the game.
On December 30, 2019, the Beijing-Zhangjiakou High-speed Railway was officially opened to traffic. As an important part of China's "eight vertical and eight horizontal" high-speed railway network, it will provide transportation and operation service guarantee for the three sections of the Beijing Winter Olympics.
[Concurrent] Li Sen, Director of the General Planning Department of the Beijing Winter Olympics Organizing Committee
Actively formulate policies for traffic operation during the game, encourage spectators to prefer high-speed rail, subway, and public transportation to travel; promote the use of electric vehicles and hydrogen energy vehicles in each competition area to ensure that the passenger vehicles (basic) used for the competition in the competition area use clean energy.
[Explanation] Li Sen introduced that Beijing and Zhangjiakou have also carried out afforestation projects respectively. The carbon sinks generated by the projects will neutralize the carbon emissions of the Beijing Winter Olympics, which will contribute to the improvement of the ecological environment and the protection of biodiversity in both Beijing and Zhangjiakou. Good benefits leave a green Winter Olympic heritage for future generations.
