Major initiatives
Climate change mitigation
Initiatives to achieve Net Zero
We are working to achieve “Net zero” to reduce GHG emissions (Scope 1, 2, and 3) from the entire supply chain to virtually zero by 2050.
Renewable energy for base station
SoftBank's primary business is in mobile communications, and about half of the electricity it consumes is used to power its base stations.
More than 50% of the base station power was converted to real reenergy by FY2021. The plan is to increase the ratio to 70% by FY2022, and we will promote the phased conversion to renewable energy to reduce greenhouse gas emissions.
Group company initiatives
Z Holdings has announced the “2030 Carbon Neutral Declaration” to reduce greenhouse gas (GHG) emissions from the business activities of all ZHD Group companies, including its subsidiaries Yahoo, LINE, ASKUL, and ZOZO, to virtually zero by fiscal year 2030 In June 2022, we joined “RE100,” an international initiative to declare that 100% of the electricity used in our business activities will come from renewable energy sources.
Tree planting activities by employees
With the cooperation of the “NPO CCC Furano Nature School” led by Mr. Satoshi Kuramoto, we hold an original program “Summer Holiday Nature School for Parents and Children” for our employees with the themes of “building healthy relationships between parents and children” and “thinking about the environment and nature”.
Since its inception in 2007, a total of more than 250 parents and children have participated in activities such as planting trees on former golf course sites and returning them to their original forests for the future.
Smart forestry R&D

Through technical support provided by e-kakashi, we will contribute to the realization of sustainable agriculture not only in Japan but also in the world.
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.
