Promoting "Net Zero"
throughout the supply chain
In addition to its existing "Carbon Neutral 2030" declaration, which aims to reduce GHG emissions (“Scope 1” and “Scope 2”) from business processes and energy consumption to virtually zero by 2030, SoftBank will work to remove supply chain emissions (“Scope 3”), which includes GHG emissions generated by business partners.
Efforts toward Net Zero
Utilization of renewable energy
Replacing the power
by base stations
with renewable energy
The annual greenhouse gas emissions from our business activities amount to approximately 680,000 tons of CO2 equivalent (fiscal year 2019 results), which is equivalent to the emissions of approximately 250,000 average households Within those, more than half of our electricity is used at mobile phone base stations (hereinafter “base stations”), where our core business is mobile telecommunications. In order to reduce greenhouse gas emissions, we are switching to electricity*1 from substantial renewable energy supplied by our subsidiary SB Energy Corp., and has achieved the goal of switching 30% of the electricity used by base stations to substantial renewable energy by fiscal year 2020 and more than 50% by fiscal year 2021.In fiscal year2022, more than 70% of the electricity used at base stations will be switched in stages to substantially renewable energy sources.
In addition, we are working to reduce greenhouse gas emissions by gradually switching to substantially renewable energy sources for power used by facilities and equipment other than base stations, and we are also working to reduce power consumption by further saving energy in network facilities through the replacement of energy-saving equipment and more efficient air conditioning systems.

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. In October 2021, in collaboration with Empower Greentech Inc. of the U.S., we succeeded in demonstrating a lightweight, high-capacity, high mass energy density lithium metal battery whose mass energy density is more than twice that of conventional batteries (520 Wh/kg class).
By encouraging research development and early commercialization, we aim to serve as a platform to promote the development of next-generation batteries.
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.
