Beijing Institute of Technology calculations: Beijing Winter Olympics to reduce carbon emissions of 950,000 to 1.03 million tons
The 2022 Beijing Winter Olympics is the first major international event to be held in China after the country proposed a dual carbon target.Beijing Winter Olympics has reduced carbon dioxide emissions by 950,000 to 1.03 million tons by implementing more than 30 low-carbon measures, according to the energy and Environmental Policy Research Center of Beijing Institute of Technology.It is estimated that the remaining carbon dioxide emissions after the implementation of emission reduction measures will be 1.13 to 1.35 million tons, and the remaining carbon emissions can be further offset by carbon compensation mechanisms such as forestry carbon sinks, carbon quotas independently donated by enterprises, and carbon inclusion.Responsible for measuring the Beijing Olympics the low-carbon technologies of emission reductions and events of the overall carbon emissions is the Beijing institute of technology related project team, they designed its carbon emissions “measurement – calculate – control -” key technology system for the Beijing Olympics carbon use abacus, emissions of carbon dioxide account is clear.Experts point out that the carbon emission of the Winter Olympics involves three stages before, during and after the games, as well as the discrete dynamic changes of activities such as personnel, buildings, equipment, materials and environment.Whole life cycle of carbon emissions come from where, how many, how to reduce, effect how, become the core of green do the assessment tasks, there are unknown to man – machine – – ring based data, carbon emissions calculates boundary is differ, national technical applicability and feasibility of difference is bigger, reduction effect evaluation standard key problems such as missing,There is an urgent need for a measurable, assessable, adjustable and portable technical system to scientifically quantify and evaluate the actions and results of the Beijing Winter Olympics in terms of carbon neutrality.According to the introduction, starting from September 2021, the Low-carbon technology management team of Beijing Institute of Technology will take the lead,United Nations oval, tsinghua university, Beijing university of aeronautics and astronautics, hefei institute of material science, Chinese Academy of Sciences, shandong shun create carbon for green building technology co., LTD., Beijing science and technology co., LTD., Beijing green exchange co., LTD., Beijing OTT beauty, science and technology co., LTD., and other eight units around the task and the key problem,To jointly undertake the project of “Key technologies and Demonstration application of Low-carbon Winter Olympics Monitoring and Carbon neutral Regulation” of the National Key RESEARCH and Development Program for The Winter Olympics.Beijing institute of technology of project team independently designed and developed carbon emissions – calculate – control – “test for” technical system, the successful development of the games are carbon measuring platform, man – machine – are relevant to its carbon emissions – ring data monitoring, carbon accounting, evaluation and control function of integrated into an organic whole, to carry out the “carbon inventory”, the scientific quantitative emission reduction contribution of various technique,The assessment of carbon emission reduction for the Beijing Winter Olympics is based on evidence, verifiable and verifiable. The equipment developed by the project has been applied in the “Ice Ribbon” and the “Ice Cube” of the National Aquatics Center.North polytechnic project team members, Beijing institute of technology in energy and environmental policy research center, deputy director of the Yu Biying told the media, “we are in the region of the venue, energy dissipation device, the audience entrance dozens of points installed intelligent monitoring equipment, such as real time collecting carbon dioxide concentrations, traffic, electric power, venues such as temperature and humidity man-machine ring data, that is” test “.The data is fed back to the Winter Olympics carbon measurement platform, which automatically calculates the carbon emissions of each area of the venue. This is called ‘calculate’.”At the same time, the “measure-calculation-control-plan” technology system will generate a database of carbon emission control schemes for the Winter Olympics according to the data, quantify the emission reduction effects of different types and carbon control measures, and put forward carbon neutral control schemes.On the west side of the “Ice Ribbon” at the National Speed Skating Stadium, you can see two sets of red, blue and green wind strips standing on the top of a gray and White House, 6 meters by 2.5 meters high.This is the “zero carbon house” developed by Beijing Institute of Technology.Take this as an example, Yu biying said, “Rooftop fans and solar photovoltaic panels are used to supply clean energy to meet the needs of indoor air conditioning, office equipment, external walls and other large screens. It is equipped with a heat recovery system and electric energy storage system to achieve energy self-sufficiency and intelligent regulation to achieve zero carbon emissions.”The building itself is made of environmentally friendly and recyclable steel, and the cabin can be removed, moved and recycled.”Delta Beijing Olympics derivative effect of beijing-tianjin-hebei region development in order to further evaluate the Beijing Olympics to the impact of the development of the beijing-tianjin-hebei region, north polytechnic project team from “economy – society – environment – ecological” four dimensions to identify key factors, comprehensive impact assessment model build events, create synergy development index,Comprehensively evaluate the multi-dimensional derivative effects of preparations for the Winter Olympics on the coordinated development of Beijing, Tianjin and Hebei.It can be predicted that the Beijing Winter Olympics will effectively promote the coordinated development of The Beijing-Tianjin-Hebei region and the sustainable development of the region.The emission reduction principles of various low-carbon measures implemented in Beijing Winter Olympics can be divided into four categories: energy saving, clean energy use, material saving and low-carbon material replacement.(1) Energy conservation, which means to improve efficiency and reduce energy consumption through technological upgrading or the construction of intelligent energy management and control system, so as to reduce carbon emissions generated by thermal power generation or direct combustion of fossil energy such as coal, oil and gas.(2) Clean energy use, that is, reduce the use or no use of fossil fuels for power generation and heating, and try to use renewable energy to avoid carbon emissions from fossil energy consumption.(3) Hosting the Winter Olympics not only requires energy supply, but also consumes a lot of materials, such as steel, cement, glass and paint, in terms of infrastructure construction and material consumption.From the perspective of life cycle, these materials require energy input in the production and transportation process, which will produce carbon emissions. Material saving means to reduce such carbon emissions by reducing the use of materials.(4) Low-carbon material substitution, that is, to reduce life cycle carbon emissions caused by material consumption by using materials that are more energy-efficient and low-carbon in the production and transportation process.(All charts and photos in this article are from the Center for Energy and Environmental Policy, Beijing Institute of Technology.
