Utilization of renewable energy
Replacing the power
used
by base stations
with renewable energy
The annual volume of greenhouse gas emissions due to our business activities is equivalent to approximately 680,000 tons of CO2 (actual results for FY 2019), which is comparable to roughly 250,000 average households. Within those emission figures, more than half of the electrical power used by the mobile communication business, which is our main line of business, is used by approximately 230,000 mobile telephone base stations (hereinafter, "base stations"). In order to reduce greenhouse gases, we are promoting a transition to electricity*1 sourced from virtual renewable energy provided by our subsidiary SB Energy Corp. and achieved a level of 30% virtual renewable energy in base station power consumption in FY 2020. We are gradually transitioning to a level of 50% or more in FY 2021 and 70% or more in FY 2022 for the use of virtual renewable energy in base station power consumption.
Moreover, we are also promoting a sequential transition to virtual renewable energy for power consumption by non-base station facilities and equipment to reduce greenhouse gases.
In addition, SB Energy Corp., a subsidiary of SoftBank Group Corp. that generates electricity from renewable sources, generates electric power at 45 locations including the "Tochigimotegi Solar Park." In order to further utilize renewable energy and reduce greenhouse gases, we are considering the direct procurement of electrical power generated by SB Energy Corp.

- *1 Electricity which is essentially 100% renewable energy utilizing non-fossil certificates that specify renewable energy.
Energy-saving measures utilizing cutting-edge technologies
Power efficiency utilizing
AI, IoT, etc.
It is said that the impact on the global environment can be predicted by utilizing AI, IoT, big data, and other cutting-edge technologies to analyze the massive amount of environmental data through AI learning features. In order to become able to implement various countermeasures based on those predictions, the world's attention is focused on the application of cutting-edge technologies to environmental problems.
We are striving to maximally utilize cutting-edge technologies and synergies between group companies to achieve power efficiency in our facilities and equipment and implement measures to reduce the environmental load.
Reducing the environmental load through the development of next-generation batteries
We are striving to reduce the environmental load through research and development aimed at the development and practical application of next-generation batteries. Power consumption is increasing through the evolution of devices, which is leading to an increase in CO2 emissions. Increasing the capacity and energy density of batteries equipped in devices can enhance the performance and efficiency of devices and equipment and reduce the load on the environment.
Moreover, the "SoftBank Next-generation Battery Lab" was established in June 2021. The lab evaluates and tests various next-generation batteries from around the world, and aims to become a platform for accelerating the development of next-generation batteries by driving research and development and practical application at an early stage.
Realizing a communications infrastructure
with a low environmental load
Our subsidiary HAPSMobile Inc. built the "HAPS (High Altitude Platform Station)" system, which provides a communications network from the sky, and developed an unmanned aircraft called the "Sunglider" that can continue to fly in the stratosphere. SoftBank aims to realize infrastructure with a low environmental load by providing stable flight and communication services through the development of solar power generation and storage technologies.

What does "carbon neutrality" mean?
"Carbon neutrality" means achieving net zero emissions of greenhouse gases emitted through human activity by absorbing or removing them through human activity. As climate change is becoming a worldwide issue, the Japanese government has declared that it will become carbon neutral by 2050. The greenhouse gas reduction is a topic that not only countries and local governments but also companies and individuals should pursue. Companies around the world are paying attention to carbon neutrality and starting to work on it.
Furthermore, the Carbon-neutral 2030 that we aim to achieve refers to an initiative to achieve net zero greenhouse gas emissions by 2030.
