 Mobile phone to global warming? Experts: exaggerated, mobile phones will increase carbon emissions.


Lutfi Belhill, a researcher at McMaster University in the country, believes that information and communication technology products such as smart phones are one of the drivers of global warming. Does the use of mobile phones really lead to global warming? Science and Technology Daily reporter interviewed experts with questions. Discarded mobile phones. Data map The meaning of the study was misinterpreted This report is not accurate enough to misinterpret the meaning of the report. Recently, He Liangnian, a professor of chemistry at the Nankai University, said in an interview with a Science Daily reporter that as soon as the report came out, he downloaded the Canadian colleagues Research Report. This research is not dedicated to smartphones. The report tracks the carbon footprint and trends of global information and communications technology by 2040, and smart phones are only part of it. He Liangnian said the report showed that in the global information and communications technology carbon emissions, smartphones accounted for 4% in 2010, or 11% in 2020, and the carbon emissions of the data center were expected to increase from 33% to 45%. In his view, the news was somewhat exaggerated. He Liangnian said that climate change is a complex problem, and whether it has a direct relationship with carbon emissions remains to be further verified, and an application research report is difficult to make it clear. The use of mobile phones will increase carbon emissions Although it does not fully agree with the idea that smartphones are global warming pushes, He Liangnian believes that using smartphones does objectively increase carbon emissions. Like icebergs floating on the sea, what is visible is only a small part, and most of them are hidden under water. So is the carbon emissions of smartphones. He Liangnian said whether the use of smartphones to increase carbon emissions should be calculated in its life cycle, from cell phone production, use to scrap dismantling. Simply calling or playing online, there is no increase in carbon emissions on the surface, but the amount of carbon emissions is actually increased if all the necessary conditions for the completion of these two behaviors are calculated. He Liangnian took the call as an example, for example, the normal voice calls need to be realized by means of base station connection and data center data exchange. In this process, the call itself does not produce carbon emissions, but the base stations and data centers that support the call need to consume a large amount of energy, such as electricity, which increase the energy consumption of the infrastructure. As early as 5 years ago, the Daily Mail reported a study on the use of smartphones. Scientists found that 3G data traffic on a cell phone or tablet is the biggest energy consumption, and its carbon emissions are 8 times as much as that of a WiFi, equivalent to the energy consumed by a car for 10 miles. The need to pay attention to the waste mobile carbon emission The problem of carbon emissions caused by the use of smart phones can be alleviated by clean energy such as wind energy and solar energy in the future. Compared to the use of links, He Liangnian believes that the carbon emissions of mobile phones in the process of production and scrap need more attention. The discarded mobile phone is a big carbon footprint. He Liangnian said, nowadays the life expectancy of mobile phones is getting shorter and shorter, averaging two or three years. The replacement frequency of mobile phones is getting higher and higher, but the old mobile phones that are eliminated are lack of professional recycling. This will not only cause heavy metal and other environmental pollution, but also the plastic shell and plastic products in the process of degradation, will produce a large amount of carbon dioxide, invisible and carbon emissions. He Liangnians fears are not unreasonable. According to the data from the Ministry of industry and information, China has accumulated about 1 billion 830 million mobile phone stocks since 2014. The Ministry forecasts that the number of mobile phones will reach 461 million units and 499 million units in 2018 and 2019 respectively. After the 5G business, the number of used mobile phones will increase to 524 million. At the same time, the domestic waste mobile phone recycling industry is short of specialized and large-scale leading enterprises, and the scattered small enterprises are fighting each other, which not only increases the cost and energy consumption, but also increases the carbon emissions indirectly. The reporter learned that China had formally implemented the regulations for the management of waste electrical and electronic products recovery and management as early as January 2011, but the recycling of mobile phones has not been included in the regulations. The old mobile phone recycling policy has become a blind spot for the recycling of waste electronic products. A large number of old plastic parts of mobile phones are scattered and discarded, letting the wind and sun shine and naturally degrade. This process is very slow and produces a lot of carbon emissions. In He Liangnians view, to reduce the carbon emissions from smart phone use, we need to be multi pronged. On the one hand, we should vigorously advocate environmental protection and saving awareness, encourage users to take the initiative to reduce the frequency of mobile phone replacement and reduce the frequency of use. More importantly, it is necessary to strengthen the binding force in the production recovery process, encourage enterprises to innovate boldly, and use more recycling materials and environmental protection components that do not affect the appearance and performance.
