1、 低碳环保绿色冬奥 北京冬奥与环保话题扩展阅读材料 Olympic venues deliver on environmental protectionEnvironmental protection has been made a priority for venues（场馆）in the Zhangjiakou competition zone at the upcoming 2022 Beijing Winter Olympics.The location of the National Ski Jumping Center was carefully selected to avoid
2、 the use of underground water for snowmaking, said Wang Jingxian, venue and infrastructure（基础设施）manager of the center in the Games co-host city of Zhangjiakou, Hebei province.Before constructing the venue halfway up the mountains in the Guyangshu area, we calculated the volume of surface water that
3、can be collected from the mountains in summer, through means such as rainfall and natural springs. Scientific research data has shown that such water is enough for snowmaking and supporting the operations of the venues, Wang said.A reservoir（蓄水池）with a capacity of 200,000 cubic meters was built to c
4、ollect water for the venues in Guyangshu, including the National Ski Jumping Center and the nearby National Cross-Country Skiing Center.Li Zhenlong, venue and infrastructure manager of the skiing center, said the venue also has five smaller water storage facilities eradicating（根除）the need to use und
5、erground water and harm the environment during snowmaking.Also, we have planted many trees while constructing the courses. Furthermore, the venue is 100 percent powered by wind and solar energy. We have made great efforts to achieve sustainable development, Li said.To minimize carbon dioxide emissio
6、ns, about 700 hydrogen-powered vehicles will be used in the Zhangjiakou competition zone, said Wang Hewu, executive (主管) director of the Zhangjiakou Hydrogen and Renewable Energy Research Institute.The vehicles will be used for transportation and logistics (物流) operations during the Games, which wil
7、l run from Feb 4 to 20.The emission of hydrogen-powered vehicles is just pure water so it wont cause any pollution. Furthermore, the hydrogen fueling the vehicles is produced with wind power so the whole process is green, Wang said.A hydrogen-powered bus can reduce carbon dioxide emissions by 11.8 m
8、etric tons over 10,000 kilometers. Such buses can run smoothly at -20 C, and their safety and reliability have been tested, Wang said.Currently, there are more than 444 hydrogen-powered buses in operation in Zhangjiakou, covering nine bus routes in the city. They have run about 20 million km and car
9、ried more than 62 million passengers, according to the local government.Zhangjiakou has two hydrogen production plants and eight hydrogen refueling stations, which help guarantee the operation of the hydrogen-powered vehicles, Wang said.Delivering a sustainable futureThe concepts of green Games and
10、sustainability have been embedded (嵌入) in the entire process of preparing for and delivering the Beijing Winter Olympics, an official from the organizing committee stressed on Wednesday.We can summarize this practice and outcome with the key words low-carbon management and ecological conservation, L
11、i Sen, director-general of the general planning department of the Beijing 2022 organizing committee, said at a daily briefing (情况介绍会).China plans to peak its carbon emissions before 2030 and achieve carbon neutrality（碳中和）before 2060. At Beijing 2022, the country is translating those pledges（诺言）into
12、concrete actions.Beijing made staging carbon-neutral Games a key component（组成部分）of its bid（努力）for the 2022 Winter Olympics, Li said, adding that it has fulfilled this promise in terms of venues, energy, transportation and even administrative（经营）work.Six venues used for the 2008 Summer Olympics have
13、been transformed for use at the 2022 Winter Games, including the National Aquatics Centredubbed the Ice Cube for the duration of Beijing 2022the Capital Indoor Stadium and Wukesong Arena.Reusing the old venues has reduced carbon emissions compared to the alternative of building new ones, Li added.As
14、 for ecological conservation, he said organizers have prioritized（优先考虑）resource saving and environmental friendliness.We have implemented（实现）integrated（综合的）plans for ecological conservation to protect the mountains and rivers, Li said.Citing the Yanqing competition zone, Li said that organizers carr
15、ied out environmental impact assessment work before the Games and integrated sustainability into the planning and construction of the venues, including the protections of plants.We relocated those plants in the construction area to nearby spots or other conservation areas that were specifically buil
16、t for them. Although they were relocated, they are carefully tended to and are growing well, Li said.Beijing 2022s sustainability plans have garnered（获得）praise from the International Olympic Committee.In the time of Beijing 2008 and Beijing 2022, the commitment（承诺）to sustainability has evolved treme
17、ndously, both in sport and in China and in Beijing in particular, said Marie Sallois, IOC director of corporate and sustainable development.And as the world is racing to avoid the dramatic effects of climate change, we have put sustainability and climate action at the very center of this strategy fo
18、r the future of the Olympic Movement.On one hand, we would like the Games to be at the forefront（第一线）of sustainability, and on the other hand, we would like the Games to act as a catalyst（诱导者）for sustainable development in the host territory（东道国）. This means the approach has evolved, and the Games have to adapt to the local context and adapt to the needs of the host and not the other way around. 4 / 4
