• Bridgestone has been recognized for leadership in corporate transparency and performance on climate change by global environmental non-profit CDP, securing a place on its annual ‘A List’.
• Being included in the ‘A List’ is a strong recognition of Bridgestone’s environmental actions and progress towards its long-term environmental vision of contributing toward carbon neutrality.
• These initiatives align with the “Bridgestone E8 Commitment” which accelerates the company’s transformation to a Sustainable Solutions Company.

Bridgestone strives to contribute to a realization of carbon neutrality across its value chain. The Group’s efforts include acquisition of SBT (Science Based Targets) certification and increasing use of renewable energy, which we believe have led to the selections of ‘A List’. In 2023, the Group has acquired SBT certification for its medium-term CO2 emissions reduction target for 2030 (Scope 1, 2 and Scope 3) ^*3. The Group also has been transitioning to renewable energy sources for purchased electricity globally^*4 and installing solar power generation system in its plants^*5. With a guiding framework “Bridgestone E8 Commitment” ^*6, Bridgestone commits to realizing sustainable society by co-creating value together with society, partners and customers while integrating sustainability and business^*7.

All the notes and stuff

1. CDP is a global non-profit that runs the world’s environmental disclosure system for companies, cities, states and regions. Founded in 2000 and working with more than 740 financial institutions with over $136 trillion in assets, CDP pioneered using capital markets and corporate procurement to motivate companies to disclose their environmental impacts, and to reduce greenhouse gas emissions, safeguard water resources and protect forests.
2. Over 24,000 organizations around the world disclosed data through CDP in 2023, with more than 23,000 companies – including listed companies worth two thirds global market capitalization – and over 1,100 cities, states and regions. Fully TCFD aligned, CDP holds the largest environmental database in the world, and CDP scores are widely used to drive investment and procurement decisions towards a zero carbon, sustainable and resilient economy. CDP is a founding member of the Science Based Targets initiative, We Mean Business Coalition, The Investor Agenda and the Net Zero Asset Managers initiative.

Bridgestone Group

7. The Bridgestone Group established its corporate commitment, the “Bridgestone E8 Commitment,” to help it realize its vision: “Toward 2050, Bridgestone continues to provide social value and customer value as a sustainable solutions company.” This commitment will serve as the Group’s axis to drive management while earning the trust of future generations. The “Bridgestone E8 Commitment” consists of eight uniquely Bridgestone values starting with the letter “E” (Energy, Ecology, Efficiency, Extension, Economy, Emotion, Ease, and Empowerment) that the Group will commit to creating through distinctly Bridgestone purposes and processes, together with employees, society, partners, and customers to help realize a sustainable society. https://www.bridgestone.com/corporate/news/pdf/2022030101.pdf

• Bridgestone has newly transitioned all the electricity purchased to renewable energy sources at six tire and raw materials plants in Japan.
• These initiatives since 2021 will achieve the renewable energy ratio (electricity) used at production bases in Japan to around 90%.
• These efforts toward Green & Smart factory support for a carbon neutral mobility society and align with a corporate commitment “Bridgestone E8 Commitment” which accelerates transformation to a sustainable solutions company.

Bridgestone Corporation today announced that it has successfully transitioned all the electricity purchased to renewable energy sources at six tire and raw materials plants in Japan. The Company has also began transitioning to renewable energy sources at two chemical and industrial products plants (Seki and Kumamoto Plant), and it plans to systematically expand use of renewable energy sources going forward. In addition to the initiative in 2021 when the Company transitioned to renewable energy sources for 100% of the electricity purchased at four tire plants,*1 the transitions this time will raise the renewable energy ratio (electricity) used at production bases in Japan to around 90%.*2

By promoting the use of renewable energy sources, Bridgestone seeks to fulfill the corporate commitment of “Energy: Committed to the realization of a carbon neutral mobility society” described in the “Bridgestone E8 Commitment.”*

Bridgestone has placed sustainability at the core of its management and business and strives to realize its vision of “Toward 2050, Bridgestone continues to provide social and customer value as a sustainable solutions company.” Bridgestone is accelerating initiatives for contributing to a realization of carbon neutrality and a circular economy across the entire value chain, in all of its “produce and sell,” “use,” and “renew” phases of its Dan-Totsu Products and evolving its unique Sustainability Business Model that ensures integration of sustainability into business model toward nature positive. *

Regarding the realization of carbon neutrality, Bridgestone aims to achieve its target of reducing absolute CO2 emissions (Scope 1 and 2) by 50% by 2030, compared to 2011, and achieving carbon neutrality by 2050. Bridgestone’s 2030 Long Term Strategic Aspiration* also describes its efforts to promote the Green & Smart factory. Specially, Bridgestone seeks to source more than 50% of its energy (electricity) from renewable energy by 2023 and challenge to achieve approx. 100% renewable energy (electricity) by 2030. Bridgestone has transitioned to renewable energy sources for all electricity purchased at all of Bridgestone EMIA’s locations in Europe and two plants in China (Tianjin and Wuxi) in addition to plants in Japan. Bridgestone has also begun using solar power at plants in Japan, * Thailand, the United States, and Europe.

Looking ahead, Bridgestone intends to transition to renewable energy sources for the electricity purchased at all of its bases while also accelerating CO2 emissions reductions through the expansion of solar power generation and the improvement of energy efficiency.

The following Bridgestone plants in Japan source renewable energy for 100% of purchased electricity.

Sumitomo Rubber Industries and Kansai University have developed a new technology to generate electric power from the rotation of a tyre.

The research, undertaken by Professor Hiroshi Tani of Kansai University, found that by installing an energy harvester inside a tyre, static electricity can be converted to clean energy.

This energy harvester takes advantage of a type of static electricity called frictional charging, which is formed each time a tyres footprint deforms as it rotates along the road. It is believed that this technology holds great potential for practical applications such as a power source for many automotive digital tools.

Sumitomo Rubber Industries (SRI) have been working to introduce new automotive solution services using tools that take advantage of a wide range of data. This follows the “Smart Tyre Concept” development from SRI that aims to respond to the sweeping changes in the automotive industry and demand for greater safety and environmental performance for consumers.

SRI are confident that the results of this latest research will lead to practical applications for this new technology as a power source for sensors used in TPMS (Tire Pressure Monitoring System) and other automotive devices, contributing to the creation of future services that make use of digital tools without the need for batteries.

In October 2018, this research theme was selected by the Japan Science and Technology as a Type FS Seed Project ^* under A-STEP (Adaptable and Seamless Technology Transfer Program through Target-Driven R&D). Moving forward, SRI will continue working to advance this research with support from the Japan Science and Technology Agency.

^*A program supporting research and development projects undertaken jointly by academia and enterprise in order to perform feasibility and application studies based on the results of academic research related to technological “seeds,” with the aim of producing new core technologies.
