Bytedance practice energy saving and emission reduction

On March 25, Beijing ByteDance released the 2020 Corporate Social Responsibility Report (hereinafter referred to as the "Report"). The report shows that in the past year, the company has further expanded its scope to the field of environmental protection based on its social responsibility work such as information poverty alleviation, campaign assistance to farmers, job creation, and platform autonomy.

Bytedance practice energy saving and emission reduction

Compared with traditional industries, high-tech companies have a lower impact on the natural environment, but the energy consumption and carbon emissions of large-scale data centers on which their operations depend are increasing. According to the National Energy Administration, the power consumption of data centers in my country exceeded 200 billion kilowatt-hours last year, a record high, and the proportion of electricity consumption in the whole society rose to 2.7%. In addition, according to carbon management software provider carbon resistance calculations, data centers currently account for more than 90% of the total carbon emissions of Internet technology companies.

The report shows that Bytedance has achieved remarkable results in building a green data center. The company is deeply involved in the energy conservation and emission reduction work of all large-scale data centers that provide services for it. The report pointed out that ByteDance prioritizes environmental protection factors in the site selection, design and construction process of the data center. Among them, data centers are mostly located in clean energy-rich areas such as wind and solar energy, and the renewable energy utilization rate can reach up to 100%. At the same time, the data center construction adopts factory prefabricated design and steel frame to reduce construction pollution.

In 2020, ByteDance data center adopts leading "indirect evaporative natural cooling technology", which has reduced the power usage efficiency (PUE) of traditional data center to 1.14, exceeding the industry average. According to a report by the China Energy News in August 2020, "The average PUE of domestic data centers is between 1.8 and 2.0, and the PUE of small and medium-sized computer rooms is higher, mostly above 2.5." PUE is used to measure the energy efficiency of data centers. Its benchmark value is 2. The closer the value is to 1, the higher the energy efficiency.

This result is also better than the national standard. The Ministry of Industry and Information Technology, the National Agency Affairs Administration, and the National Energy Administration have previously announced that by 2022, "the average energy consumption of data centers will basically reach the international advanced level, and the PUE of newly built large and ultra-large data centers will reach 1.4 or less."

The above report also shows that ByteDance adheres to a low-carbon office approach: strictly follow the principles of environmental protection in the design, construction and daily use of the office area to minimize environmental pollution and waste of resources and energy. According to reports, the company's office buildings all use smart lighting systems, using LED low-power lamps, and automatically switch lighting through personnel induction to avoid energy loss caused by forgetting to turn off the lights after get off work. 60% of the shuttle buses in the Bytedance work area use new energy. Last year, this alone reduced carbon dioxide emissions by 65.08 tons. All employees of the company use paperless office. Last year, over 20 million documents were created on Feishu. If printed and stacked on A4 paper, it would be close to the altitude of Mount Everest.

In addition, ByteDance is trying to carry out green public welfare activities. In 2020, the company, together with the Ministry of Natural Resources and the National Forestry and Grass Administration, launched a number of environmental protection activities, including "Unconditional Writing Day? Love the Earth Special", "Living Treasure", "I speak for nature", etc., calling for care for nature. Ecological environment, protect wild animals and plants, and be the guardians of the earth together.
