2022-07-08
What will happen if the global temperature continues to rise by 1.5 degrees Celsius? 70% to 90% of coral reefs die, specific species disappear forever, seawater will inundate more land, floods and extreme weather occur frequently... The report of the United Nations Intergovernmental Panel on climate change (IPCC) shows that since the industrial revolution, the average temperature of the earth has risen by about 1.1 degrees Celsius, the highest level in about 125000 years. To slow down this process, the new generation of information technology has great potential. The new generation of information and communication technology represented by 5g plays an increasingly important role in accelerating the process of energy conservation and emission reduction and protecting the global natural ecology while enabling the digital transformation of the whole industry. 5g technology is deeply integrated with key carbon emission industries such as agriculture, manufacturing, energy industry and transportation industry, effectively improving energy and resource utilization, and achieving "double improvement" of high-quality production and carbon efficiency. 5g is a powerful tool to deal with climate change Global climate change and sustainable development are social, economic and environmental issues of great concern to everyone, every enterprise and every industry. Statistics show that nearly one-third of the Fortune Global 500 companies have committed to achieving major climate change goals by 2030, most of which are committed to achieving "carbon neutrality" or net zero emissions. In China, the "14th five year plan" clearly puts forward the goal of "double carbon", striving to achieve "carbon peak" by 2030 and "carbon neutralization" by 2060. The digital economy should first be a green economy, and the intelligent world should also be a green world. 5g technology plays an indispensable role in the process of exploring and building a more sustainable and greener future. According to the report "connectivity and 5g make industry decarbonization possible" released by MIT Technology Review insight and Ericsson, mobile infrastructure is the only and key driving factor for decarbonization. Connectivity, especially 5g, makes the expansion and rapid growth of digitalization possible. Broadband cellular connection through 5g network infrastructure is a powerful and direct driving factor for carbon emission reduction. Why can 5g become a technical tool to enable green and sustainable development? According to Angela Baker, chief sustainable development officer of Qualcomm, 5g is crucial to the world of intelligent interconnection between human beings and all things with its speed, ultra-low delay, ultra-large capacity and high reliability comparable to optical fiber. 5g has the characteristics of large bandwidth, low delay, wide connection and high reliability. With 5g, the terminal can be connected to the cloud in real time, helping to accelerate the digital transformation of many industries, bringing new services, new business models, new experiences and real-time information exchange. With the help of these capabilities, 5g has become a powerful tool to deal with global climate change. With the help of strong network capabilities, 5g can help enterprises, factories, logistics networks, power enterprises and other institutions to achieve more efficient, more conscious and more purposeful operations, ensuring that these enterprises meet the requirements of sustainable development. The forecast shows that through the further integration of 5g and advanced technologies in other industries, the carbon emissions of manufacturing and transportation are expected to be reduced by more than 50% by 2030, so that the energy industry can achieve the goal of energy conservation and emission reduction. 5g is not only a new generation of mobile technology, but also an open innovation platform, which will have a direct impact on many industries. From intelligent manufacturing and public transportation systems, to the smart grid supporting electric vehicles and the use of renewable energy, to more efficient logistics, 5g provides these industries with a more green and efficient connection capability. 5g technology is still evolving. In this process, 5g will play a more prominent role in enabling green sustainable development. The data shows that the energy efficiency of 4G network is 7 ~ 10 times that of 3G, and that of 5g network is 20 times that of 4G. In the future, with the continuous evolution of new technologies, the energy efficiency of 5g will be further doubled. Based on the growing trend of network traffic, it is necessary to drive the business to develop towards a high standard. If we can make full use of the energy-efficient advantages of 5g, we can reduce the energy consumption of the network. Data from Huawei shows that from 2019 to 2021, the diversion ratio of 5g traffic in Hangzhou reached about 20%, and the network energy efficiency increased by 3.5 times. In addition, if an enterprise can achieve cost reduction and efficiency increase while using 5g network to create a disruptive business path that can achieve low-carbon results, it can be described as a "win-win". For example, the intelligent system digital mobile network integrated with 5g technology has been used by more and more enterprises for real-time monitoring, management and reducing energy and resource consumption. If the smart solutions of these enterprises can be deeply promoted in the industry, the huge economic and social benefits brought by "decarbonization" will be reflected in the whole society. 5g is applied on the ground in "large" carbon emission enterprises "Decarbonization" is an important part of coping with climate change. Energy, manufacturing and transportation are currently recognized as the "major carbon emitters" in the world. Data show that energy use accounts for about two-thirds of greenhouse gas emissions. The manufacturing industry produces about 17billion tons of carbon dioxide equivalent every year, accounting for 32% of the global total. The total annual emission of transportation is 8.6 billion tons of carbon dioxide equivalent, accounting for 16% of the global total. There is no doubt that if these industries with serious carbon emissions can achieve "decarbonization", it will greatly promote mankind to reach the goal process of limiting the temperature rise to less than 1.5 degrees Celsius in the Paris Agreement. 5g connection is crucial for these three industries to achieve "decarbonization". In the field of energy, 5g can help build a smarter power grid, so as to better enable renewable energy and distributed power generation, and achieve energy conservation and efficiency improvement. 5g has become a key tool to enhance the edge connection of the network, allowing the local network to work separately from the main network, and helping renewable energy devices to achieve more flexible and efficient operation. With its advantages of low time delay and high reliability, 5g connected cloud network allows enterprises to achieve intelligent control goals near energy equipment, such as photovoltaic power stations in the desert and offshore wind farms, and greatly shorten the round-trip transmission time of key data and instructions. In addition, 5g will also enable the next generation smart grid to operate more stably, respond more quickly, and have more sufficient capacity to effectively respond to the growing energy demand. Transportation is also a stage for 5g to give full play to its energy-saving advantages. The cellular Internet of vehicles (c-v2x) will realize the communication between vehicles, urban infrastructure, pedestrians and the cloud, so as to achieve enhanced autonomous driving ability. The application of cellular Internet of vehicles can control vehicle lane changing, speed, braking, acceleration and other parameters, help optimize traffic flow, improve fuel efficiency, reduce traffic accidents, and make travel more environmentally friendly, safer and more pleasant. Data show that the driveway and traffic management system enabled by the cellular car network can reduce fuel consumption by up to 20%. In addition, information and communication technology represented by 5g also fills the gap of lack of collaborative innovation between infrastructure and vehicles. 5g network allows vehicle manufacturers, travel service providers, drivers, public transport networks and other different elements to connect to coordinated and sustainable transportation planning, so that the industry has more ways to "decarbonize". In the manufacturing industry, 5g fully connected factory has become an important part of intelligent manufacturing. Material recycling and reuse have a great impact on the emission reduction of manufacturing industry, which is expected to account for nearly half of the emission reduction by 2030. 5g production management system and IOT tracking can play an important role. With the help of 5g connection, we can transform the manufacturing intranet, integrate big data, cloud computing, artificial intelligence and other information technologies with manufacturing technology, build an enterprise level industrial cloud platform, and realize the transparency of factory operation and the rational allocation of production resources. Through 5g + Ar, the manufacturing enterprise Ningde times has greatly reduced the number of people taking public transportation on business trips. The reduction of about 1000 trips per year can reduce carbon emissions by 2566 tons; 5g + mobile terminal platform can fully meet the needs of mobile office and completely eliminate the use of paper documents on site. It is estimated that the annual saving of paper consumption is equivalent to cutting 7516 adult trees. In addition to industries with large carbon emissions, other industries can also achieve green and sustainable development with the help of 5g. In the field of agriculture, 5g smart connected drones can monitor the use of pesticides, and then share information with drones specially responsible for precise spraying. This is expected to reduce the use of pesticides by 50%. Under the influence of the COVID-19, 5g provides enhanced connectivity so that people can work anywhere; 5g video conference can realize immersive virtual collaboration between employees and customers, reducing people's travel needs and carbon footprint Dealing with global climate change poses a difficult problem for all mankind, and 5g may provide an important technical way to solve this problem. As a new generation of information and communication technology, 5g will become the supporter and promoter of the industry's "decarbonization" and global ecological environment protection, and the goal of 1.5 degrees Celsius will also be achieved with the help of 5g.
