Huawei Song Xiaodi: Breaking five misconceptions to accelerate green development

Dr. Xiaodi Song, Chief Marketing Officer of Huawei Carrier BG, delivered a keynote speech on "5 Misconceptions of Green Development" at the Huawei Day0 Light Up the Future Keynote Summit held during MWC22 Barcelona. Dr. Song Xiaodi pointed out: "Green development is a hot topic of common concern, but just like from Newton to Einstein, classical mechanics to relativity, our perception of things is an upward spiral process. Green development currently has five cognitive misconceptions, and we need to break the misconceptions and reveal the truth as soon as possible in order to accelerate the green development of the ICT industry." Song Xiaodi, Chief Marketing Officer of Huawei Carrier BG, delivered a keynote speech Myth 1: Developing the ICT industry will generate a large amount of carbon emissions. The truth is that according to the GeSI report, the ICT industry will only account for 1.97% of global carbon emissions by 2030. By applying ICT technology, it is possible to enable a thousand industries to reduce their carbon emissions by 20%, 10 times more than the ICT industry's own carbon emissions. This enabling effect is known as the carbon handprint, and the value of the "carbon handprint" makes us more determined to develop ICT infrastructure. According to Huawei's forecast, in 2030, 1YB of global data volume will be in the cloud, and if all of them adopt greener all-optical transmission technology, they can save 150 million tons of carbon emissions per year, which is equivalent to planting 200 million trees and re-greening the whole Europe. Myth 2: Excessive focus on supply chain emissions, i.e., carbon emissions from the manufacturing process of network equipment. The truth is that in the whole life cycle of network equipment, the production phase generates only 2% of carbon emissions, while the carbon emissions during the use of the equipment reach 80%-95%. We should focus on the use process of network equipment and improve the energy efficiency of network equipment through innovative technology, which is the key to reduce carbon emission in ICT industry. Myth 3: Green development is only equal to green new energy. The truth is that the green development of the ICT industry should not only vigorously develop solar energy and wind power, but also systematically consider the energy efficiency improvement of the telecom network as a whole. At the summit, Huawei released a three-tier system of green solutions to help operators achieve "More Bits, Less Watts" by systematically improving network energy efficiency through "Green Site - Green Network - Green Operation". Myth 4: The sum of device energy efficiency is equal to network energy efficiency. The truth is that the energy efficiency evaluation of a single device box cannot support scenario-based, global planning and construction decisions. Huawei suggests establishing a unified standard index system NCI to accurately evaluate and formulate energy-saving strategies for the entire network by measuring energy-efficiency indicators of communication main equipment, site support, bearer networks, data centers, etc. Myth 5: Energy consumption savings cannot affect any network indicators. The truth is that we cannot burn a candle at both ends. Deploying energy-saving features will certainly affect some network indicators, but some indicators (such as peak rate at midnight) can be compromised because it does not affect the actual user experience. In Germany, for the midnight mall, by deploying an energy-saving solution with intelligent shutdown, the base station saves 10% energy and does not affect the user experience at all, although the peak rate is slightly reduced. So, is it possible for some scenarios to consider a balance between energy saving and some network indicators while safeguarding user experience? Finally, Dr. Song Xiaodi said that Huawei has five suggestions for the green development of the ICT industry: "First, vigorously develop the ICT industry to enable the green development of thousands of industries; second, pay more attention to carbon emissions in the use phase of ICT infrastructure, not only in the production phase; third, through the "green site - green network - green operation" system, Huawei will provide a green network and green operation system. Third, through the "Green Site - Green Network - Green Operation" systemic solution, we will help operators to continuously improve network capacity and reduce energy consumption per bit to achieve More Bits, Less Watts; Fourth, we will define a unified energy efficiency index system to identify the main problems of energy consumption; Fifth, we will let user experience determine the wattage." Mobile World Congress 2022 will be held in Barcelona, Spain, from February 28 to March 3. Huawei's exhibition area is located in Hall 1, Pavilion 1H50, Fira Gran Via. Huawei is leading the future of digital networks with global operators, industry elites, opinion leaders and others to discuss in-depth industry trends, GUIDE leading the future, green development and other hot topics.
