Recently, China Unicom issued the "Carbon Peak, Carbon neutral" 14th Five-Year Action Plan, with the goal of green and low-carbon cycle development, comprehensively, systematically and deeply promote energy conservation and carbon reduction work, constantly improve the level of green communication network infrastructure, and help the green, low-carbon and high-quality development of the industry to a new level.

The construction of ecological civilization has also entered the key period from quantity change to quality change. On this occasion, China Unicom issued the 14th Five-Year Action Plan for Achieving Peak Carbon and Achieving Carbon Neutrality, explicitly implementing the "3+5+1+1" action plan.

The "3+5+1+1" action plan is rich in content.

"3" refers to the establishment of three carbon management systems -- carbon data management system, carbon footprint management system, and energy trading management system -- centering on low-carbon cycle development. By establishing and improving the three systems, we will improve the energy indicators, draw the carbon footprint of key energy-using equipment, and participate in the carbon emission rights trading market in an orderly manner.

"5" means focusing on five green development directions. First, we will promote low-carbon operation of mobile base stations, promote technologies such as minimalist station construction and tidal energy conservation, and increase the share of clean energy in the market in an orderly manner. The second is to build green and low-carbon data centers to improve the energy efficiency of the system through simple distribution of power supply and the use of natural cold sources for air conditioning. Third, we will further promote the green and low-carbon reconstruction of various types of communication room. Fourth, we will accelerate the streamlining and optimization of the network and take old equipment off the network. Fifth, we will improve the management of smart energy.

"1" means to deepen and expand joint construction and sharing, further promote joint construction and sharing of industrial infrastructure resources, and expand the scope of cooperation objects through pilot projects.The last "1" is the application of the index word energy enabling industry to help thousands of industries save energy and reduce carbon. For example, China Unicom helps the highway video cloud networking project to realize centralized and unified storage of the video cloud. Relying on 5G, vehicle-road cooperation, precise positioning and other technologies, more than 10 ports including Qingdao Port, Ningbo Port and Huanghua Port have been helped to reduce costs and increase efficiency. For the scrap processing and distribution center and the major steel mills to provide intelligent grading of scrap and other applications, promote the reuse of iron and steel renewable resources......

As early as in the "13th Five-Year Plan" period, China Unicom has done a solid job in its own energy conservation and carbon reduction work, and actively used digital means to provide relevant services to customers, and achieved six positive results. China Unicom and China Telecom have jointly built and shared 380,000 5G base stations and 205,000 4G base stations by the end of 2020, saving more than 8.9 billion KWH of electricity every year. Actively lead the improvement of energy efficiency of base stations, adopt energy-saving strategies at different levels such as symbol, channel and carrier, and pilot energy-saving schemes for 5G networks. Build green and low-carbon data centers and promote evaporative cooling, fresh air and other technologies. For example, Ningxia Zhongwei data center adopts fresh air free cooling system with PUE as low as 1.28. This project won the "Best Energy Saving Design Award" of ICT Infrastructure Energy Saving Innovation by China Communication Enterprise Association in 2018. The PUE of the Belt and Road data Center in Xinjiang is as low as 1.3 after adopting energy-saving technologies such as indirect evaporative cooling and graphene precision heating. A total of 17 data centers of China Unicom were selected as the National Green data center, accounting for 16%. Tap the energy saving potential of existing resources, focus on the transformation of high-energy communication room and IDC room in batches, and continue to streamline and optimize the network. To encourage independent innovation, the intelligent dual-cycle (fluorine pump) multi-link modular room air conditioning system and 5G BBU vertical installation frame independently developed by China Unicom have obtained national utility model patents. Giving full play to the advantages of the industry, in the Internet industry, new energy technology, vehicle road collaborative, intelligent monitoring, intelligent life, etc., with digital and intelligent services, such as China unicom power "provincial boundary toll station" cancel highway project, for the country 29 provinces networking toll of 487 provincial boundary toll station to provide highly reliable network service, The cumulative energy saving efficiency of the project is estimated to exceed 5 billion yuan.

Under the requirements of national green transformation and new development pattern, China Unicom will always stand on the height of "the biggest player in the country" to understand and treat the work of carbon peak and carbon neutral, adhere to the increase of stock together, while giving full play to the advantages of the industry, actively use modern information technology, to help thousands of industries "carbon peaking and carbon.

近日，中国联通发布《“碳达峰、碳中和”十四五行动计划》，以绿色低碳循环发展为目标，全面、系统、深入推进节能降碳工作，不断提高通信网络基础设施绿色化水平，助力行业绿色低碳高质量发展迈上新台阶。
