Participation in Japan Climate Initiative (SoftBank Group Corp. and SB Energy Corp.)

Japan Climate Initiative

SoftBank Group Corp. and SB Energy Corp. are inaugural members of the Japan Climate Initiative, a network created in 2018 to strengthen the dissemination of information and the exchange of opinions and views by companies, local authorities and NGOs that proactively tackle climate changes. The objective of the Japan Climate Initiative, which was formed by CDP Japan, WWF Japan and the Renewable Energy Institute, is to joining the front line of the global push for decarbonization from Japan. SoftBank Group is committed to promoting the initiatives of decarbonization through its own business activities while proactively addressing climate change in collaboration with various actors.

Improving energy efficiency at data centers (Yahoo Japan Corp. and IDC Frontier Inc.)

Yahoo Japan Corp. and IDC Frontier Inc. work to raise energy efficiency at the Kitakyushu Data Center (Kitakyushu City, Fukuoka). It 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, winning a number of awards as a result. 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* of 1.2. In addition, the data center analyzes and verifies energy conservation effects to continuously promote further energy conservation.

  • Power Usage Effectiveness: An indicator of data center energy efficiency, the PUE is calculated by dividing the overall power consumption of the data center by the power consumption of its IT equipment. In general, data centers in Japan commonly have a PUE value of 2.0 or less.

Reducing energy and paper consumption through “White Work Style” (SoftBank Corp.)

SoftBank corp. is engaged in reducing environmental impact through the application of information and communications technology (ICT). Through the implementation and proposal of a new way of working called “White Work Style,” work efficiency is improved while the volume of paper and energy consumed in day-to-day business is reduced.

“White Work Style” is a service that allows employees to access internal work systems and software simply by connecting to the network. Home PCs or personal iPhones and iPads can also be connected to an environment equivalent to the office PC, allowing flexibility in working time and location, such as teleworking from home, when on the move or from outside of the office.

Furthermore, with computer processing carried out on network servers rather than individual computers, computer power consumption can be reduced. By centralizing these servers at a large-scale data center, operational efficiency can be improved and overall power consumption will be reduced.
