Environmental impact data

To manage the risks and opportunities that climate change represents for SoftBank, we monitor data on environmental impacts.
The main target is set as Carbon Neutral 2030, to reach zero greenhouse gas emissions in real terms from the energy used in our business activities and so forth by 2030, aiming to achieve the SDGs. Also, we have set the target of “net-zero” which is to reduce “supply chain emissions” (Scope 1, 2, and 3), including greenhouse gas (Scope 3) emissions from suppliers and other sources, to virtually zero by 2050. In fiscal year 2021, we will achieve 50% of the electricity used at our base stations to be substantially renewable, and by fiscal year 2022 we will gradually increase this to 70%, and will also reduce greenhouse gas emissions from the electricity used at all of our facilities and equipment other than our base stations.
Please refer to the “ESG Data Book” for details of environmental impact data disclosure, including energy consumption and greenhouse gas emissions.
In principle, coverage in fiscal year 2021 will be 93% of consolidated sales.

Improving energy efficiency at data centers

Improving energy efficiency at data centers

IDC Frontier Inc. works to raise energy efficiency at data centers. Its Kitakyushu Data Center (Kitakyushu City, Fukuoka) is the first large commercial data center in Japan to adopt air conditioning using outside air. The data center has realized energy conservation through the optimization of high-density server operations and air conditioning efficiency, and as a result, has won a number of awards.

In addition, at the Shirakawa Data Center in Shirakawa City, Fukushima Prefecture, IDC Frontier - using the area's cooler climate and the high-level expertise acquired from its experience in operating the Kitakyushu Data Center - has developed an in-building external air conditioner system that combines architecture capable of drawing external air directly into the building with air conditioner functions in order to process exhaust heat from servers. This system enables the data center to use cool external air for over 90% of its air conditioning needs.

Completed in 2018, Shirakawa Data Center's building no. 5 employs a hybrid air conditioning system that combines external air and water cooling with air cooling functions. It is expected to achieve a high cooling efficiency of approximately PUE*1 of 1.2.

In addition, the data center analyzes and verifies energy conservation effects to continuously promote further energy conservation.
