Climate Change
SoftBank endorses the TCFD recommendations and strives to disclose information concerning climate change. We have set contributions through technology and business for climate change as one materiality (important issue) for us, promoting greater efficiency in power use via the IoT, and taking specific measures for climate change such as shifting to renewable energy and providing natural energy.
Support for the TCFD recommendations

In April 2020, SoftBank announced its support for the TCFD (Task Force on Climate-related Financial Disclosures)* recommendations. Based on the TCFD recommendations, we are enhancing governance and striving for active and complete information disclosure.

- *Task Force on Climate-related Financial Disclosures: an international initiative established by the Financial Stability Board in 2015 which recommends that companies disclose information about the financial impact of climate-related risks and opportunities on businesses.

Governance
The SDGs Promotion Committee was established in March 2020 as an advisory body to the Board of Directors. The President and Representative Director serves as the highest ranking person in charge of the SDGs and is responsible for all sustainability activities such as strategy with respect to climate change.
Strategy
Scenario analysis was conducted to consider strategies for adapting to projected future events due to climate change. Risks that are expected to occur by 2050, which have a particularly large financial impact on the business, including upstream and downstream of the value chain, were identified and two scenarios were considered.
The reference scenarios are as follows.
5th Assessment Report from the Intergovernmental Panel on Climate Change (IPCC) | RCP2.6 / RCP8.5, IEA(International Energy Agency) |
---|---|
Energy Technology Perspectives 2017 | B2DS, World Energy |
Outlook 2018 | SDS |
4℃ scenario
We assumed that the physical effects of climate change, such as intensification of extreme weather events, would occur while the risks of transition in technology, markets, reputation and other areas, as well as the strengthening of policies and regulations, such as climate change countermeasures, would not become apparent. For example, in the case of a disaster of the magnitude of the July 2020 torrential rains, we invested approximately 330 million yen in restoration costs. SoftBank operates approximately 230,000 cell phone base stations nationwide. Based on an analysis of the financial impacts such as restoration costs for disaster damageI, we secure a budget for disaster and are prepared to respond quickly.
Scenario | Increased frequency and severity of natural disasters | Increase in extremely hot days |
---|---|---|
Identified risks | Increase in recovery costs due to greater and more severe facility damage | Increase in air conditioning power costs |
Examined initiatives |
Strengthen initiatives to prevent and reduce disasters
|
Strengthen energy conservation initiatives
|
Period until the risks occur | Long-term | Long-term |
1.5 to 2℃ scenario
While there will be no acute or chronic physical risk due to climate change at a level that affects business, we estimated that if a carbon tax of about 6,000-14,000 yen per ton of CO2 equivalent were imposed from 2025, assuming that climate change policies and regulations are strengthened, there would be a cumulative impact of 17.5-40.7 billion yen until 2035.
Scenario | Strengthen decarbonization regulations | Increase in environmental awareness | |
---|---|---|---|
Identified risks | Increase in extremely hot days | Increase in power costs due to shift to renewable energy | Customer loss due to reputational risk if environmental initiatives are insufficient |
Examined initiatives |
|
Strengthen energy conservation initiatives

Initiative to reduce CO2 and information dissemination
