Cloud computing achieves green waters and green mountains - in the next four years, it can help reduce more than 1 billion tons of carbon dioxide

Beijing. The development of logistics industry in 2021 must be supported by perfect infrastructure. On April 23, global environmental problems are receiving extensive attention, and China has also promoted environmental protection to a key strategy. In the 14th five year plan and the long-term goal of 2035, accelerating the promotion of green and low-carbon development has become one of the planning priorities. The plan clearly proposes to support green technology innovation, promote cleaner production and promote clean, low-carbon, safe and efficient utilization of energy. Reduce the intensity of carbon emissions, support qualified places to take the lead in reaching the peak of carbon emissions, and formulate an action plan for reaching the peak of carbon emissions by 2030. In the context of increasing global attention to environmental protection (especially carbon neutralization and carbon peaking), how to optimize the design of data center, as a major energy consumer, and contribute to overall environmental protection and clean and low-carbon has increasingly become an important topic in the IT field

to this end, IDC released the global cloud computing carbon dioxide emission reduction forecast report. This is the first time in the industry to quantitatively analyze and predict the carbon dioxide emission reduction of cloud computing. The report estimates the annual carbon dioxide emissions of the data center, and calculates the annual reduction of carbon emissions in the next few years based on the number of 100000 practitioners in 2020. The results show that from 2021 to 2024, the continuous use of cloud computing can reduce more than 1 billion tons of carbon dioxide emissions

IDC has established a set of models to track the carbon emission of the data center by 98.07. The model uses the historical accumulation of IDC's long-term tracking of IT market data, including server data, cloud computing data, software deployment data, and some third-party data, such as data center power use and carbon dioxide emissions per kWh, so as to obtain the comparative information of carbon emissions between cloud data center and traditional data center

research shows that one of the key factors to reduce carbon dioxide emissions in data centers is to improve the density of computing resources, so as to achieve higher efficiency. By gathering the computing resources of discrete enterprise data centers into larger data centers, we can more effectively manage power capacity, optimize cooling facilities, and improve server utilization, so as to maximize the energy efficiency ratio of IT resources and achieve the goal of reducing emissions

at the same time, the extent of data center emission reduction varies according to the degree of carbon dioxide produced per kilowatt hour, and varies greatly among different regions and countries. Therefore, the biggest opportunity to reduce carbon emissions through cloud computing appears in areas with high carbon dioxide emissions per kilowatt hour. In contrast, in Europe and the Middle East, the carbon emissions that can be reduced by cloud computing in the next four years will be about 10%. For countries such as China that mainly generate electricity from coal, the effect of emission reduction will be more obvious. Using cloud computing technology, it is expected that China's data centers can reduce carbon dioxide emissions by nearly 50% in the next four years

by using cloud computing, users can also transfer the IT workload to be run to the remote data center without necessarily deploying the data center at the place of use to provide IT services. This is another feature of cloud computing that can reduce carbon emissions. By shifting the workload, we can make better use of clean resources such as wind and solar energy

Zhou Zhengang, assistant vice president of IDC China enterprise research department, said: the concept of green data center has existed for many years. However, with the attention of national policies to environmental protection, more and more users and investors will begin to pay attention to the direct impact of large-scale computing on carbon emissions. In order to achieve the overall goal of reducing energy consumption per unit of GDP by 13.5% and carbon dioxide emission per unit of GDP by 18% proposed in the 14th five year plan, cloud computing and data center technology of sustainable design are very important. For advanced cloud service providers, matching the workload with the availability of renewable energy will further accelerate their sustainable development goals
