Long-term renewable energy procurement contract

By newly procuring renewable energy, the Company aims over the longer term to source all electricity required for its telecommunications business from carbon neutral power.
Through long term renewable energy procurement agreements and greater use of renewable energy, the Company will reduce greenhouse gas emissions and contribute to the Company's achievement of carbon neutrality and the realization of a decarbonized society. In addition, long-term procurement agreements will support a transition to a business structure that is less susceptible to rising electricity prices.

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's learning capabilities. Because those predictions enable various countermeasures, the use of cutting-edge technologies in addressing environmental issues is attracting global attention.
In 2026, the Company developed an AI driven system that dynamically manages sleep mode control for base stations to maximize power savings and began deploying it at some base stations. This system reduces power consumption by automatically shifting selected cells to sleep mode during low traffic periods while maintaining communication quality.
Going forward, the Company will further leverage cutting-edge technologies and synergies with group companies to improve power efficiency at the Company's facilities and equipment and implement measures to reduce the environmental impact.

Reducing the environmental load
through
the development
of next-generation batteries

The Company is working to reduce environmental impact through research and development aimed at the development and practical application of next-generation batteries. As devices evolve, 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 installed in devices can enhance the performance and efficiency of devices and equipment and reduce the impact on the environment.
In addition, the "SoftBank Next-generation Battery Lab" was established in June 2021. The lab evaluates and verifies various next-generation batteries from around the world. In October 2021, in collaboration with Enpower Greentech Inc. of the U.S., the Company 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 promoting research and development and early commercialization, the Company aims to serve as a platform to promote the development of next-generation batteries.

The Company's stance
on the use of carbon credits

In pursuit of a decarbonized society by 2050, the Company supports the Paris Agreement, an international framework, and positions climate change response as a key issue.
The Group has set a target of achieving net zero greenhouse gas emissions across the Group's entire value chain by 2050 and is actively pursuing it.
Referencing the SBTi (Science Based Targets initiative) guidance, the Group gives top priority to maximizing greenhouse gas emission reductions across Scope 1, 2, and 3.
Regarding residual emissions, the Group is both promoting insetting activities by investing in and supporting activities that absorb and remove carbon within and outside the supply chain, and evaluating the use of carbon credits for offsetting.
The Company recognizes that, depending on their type, insetting activities and carbon credits can be effective means of supporting environmental restoration and the sustainable development of local communities. The Company also considers these to be initiatives that can contribute to nature-positive outcomes, which the Company supports in its environmental vision alongside climate change measures.
The Group takes a multifaceted view of increasingly diverse and complex environmental and social challenges, and is dedicated not only to reducing emissions across the supply chain but also to contributing to the development of a decarbonized society on a global scale.

Approach to carbon credit utilization

General policy
Regarding the use of carbon credits, the Company emphasizes high quality in procurement and creation, and also considers impacts on biodiversity, local communities, and human rights, as well as co-benefits.

The Company recognizes the importance of ensuring that carbon credits do not cause negative social or environmental impacts and have high reliability, transparency, and sustainability.

The Company's perspective
on carbon credit deployment

• Project types: Consider the relevance of project types, such as carbon removal, absorption and storage, to the Company's business activities when selecting credits.
• Additionality: Credits must be generated through carbon removal, absorption, or storage activities that would not occur without the project.
• Permanence: Credits must include mechanisms ensuring that carbon removal, absorption and storage activities are preserved and maintained over the long term.
• Double-Counting Prevention: There must be a system in place to ensure the same emission reductions are not claimed by multiple entities.
• Transparency: Credits should be subject to proper disclosure or third-party monitoring.
• Reliability: Credits must be underpinned by valid and reliable data, calculation, and verification methods.
• Governance: Credits must be supported by appropriate risk management and an operational framework.

Initiatives related to
Scope 3 reduction

As part of the Company's efforts to reduce Scope 3 emissions, the Company is also considering measures such as neutralization credits, permanent carbon removal, forest carbon sequestration, and oceanic carbon uptake in cases where residual emissions remain after all feasible reductions have been made. The Company has endorsed the establishment objectives of the CO2 Separation, Capture, Utilization, and Storage Consortium, which was created by the National Institute of Advanced Industrial Science and Technology to conduct research and development on CO2 separation, capture, utilization, and storage technologies. The Company's participation aims to contribute to the overall improvement of industry-wide technologies.

Additionally, the Company has joined as an initial member of the Natural Capital Credit Consortium (NCCC) and aims to promote forest conservation by contributing to the creation of carbon credits through the utilization of IT.

As part of society-wide CO2 reduction efforts, the Company launched the "Future and Coral Project" in collaboration with Onna Village, Okinawa Prefecture, which actively promotes coral planting and environmental conservation, along with numerous companies and organizations. Through coral reef conservation activities, the Company contributes to promoting ocean CO2 absorption by restoring marine ecosystems.

Furthermore, SB Power Corporation, a group company of the Company, offers a household electricity plan called "Shizen Denki", which has zero CO2 emissions. For each contract, SB Power Corporation contributes 50 yen per month as an activity support fund, providing support for forest conservation activities.

Additionally, the Company has started calculating the carbon footprint for some of the Company's products, and the Company plans to expand this assessment to cover more products in the future.

Japan Forest Regeneration
Support Project

The Company is carrying out the "Forest Regeneration Support Project" to promote environmental conservation and contribute to achieving a decarbonized society by supporting forest conservation efforts in 47 prefectural and municipal governments across Japan.^*
Through this initiative, the Company plans to donate more than 4 billion yen via Japan's corporate hometown tax program and collaborate with local governments over a 15-year period from 2025 to 2040 to contribute to sustainable forest conservation activities through tree planting. If the full amount is used for tree planting, this is equivalent to approximately 1.8 million trees.

[Note]

• * Comprising 46 prefectures and Hachioji City, Tokyo.

NatureBank

"NatureBank" is a consumer-participation tree-planting contribution program that visualizes and encourages eco-friendly behavior. It covers all 16 eco-actions offered by the Company and its Group companies, creating a mechanism that enables people to see and feel how their daily eco actions contribute to the environment. In accordance with the amount of CO2 emissions avoided^*1 through these 16 eco-actions, SoftBank plants trees that absorb an equivalent amount of CO2. The more consumers engage in eco-friendly actions, the more trees are planted, increasing collective contributions to forest conservation.

[Note]

• * CO2 reduction contributions from the use of each service and the CO2 absorption amounts of trees are estimated by the Company based on publicly available data from the government and each company.
