Environmental management

The Bridgestone Group’s Total Environmental Advanced Management System (TEAMS) serves as the foundation for Bridgestone’s environmental activities. To acquire and maintain ISO 14001 certification at its manufacturing sites, Bridgestone has implemented an Environmental Management System (EMS) framework across the Group. TEAMS was developed by adding the following two concepts to EMS:

Total: the participation of all business units, facility functions and employees throughout the Group
Advanced: the commitment to active disclosure and advanced, world-class activities

Under the TEAMS concept, each Group strategic business unit (SBU) and facility prepares and adopts an EMS using ISO 14001 methodologies. Environmental activities are then improved through the use of the plan-do-check-act (PDCA) cycle at three levels: individual facilities, SBUs, and globally.

To support TEAMS activities, Bridgestone is also working to provide and consolidate shared global information systems for use in improvements across the Group’s PDCA cycle based on analysis of each SBU’s environmental activities and data. It reinforces various infrastructure and human resource developments to ensure environmental management at SBUs and business locations.

For example, all non-manufacturing sites, including distribution centers and retail shops, conduct environmental self-assessments, grading each location’s environmental management against one of three levels (I, II, or III), using the information for further improvement by means of the PDCA cycle.

In addition, the Group holds conferences for environmental managers to enhance environmental education and cooperation across the entire Group. The training includes on-site lectures and group discussions aimed at enhancing the capabilities of environmental managers and strengthening regional cooperation.

TEAMS serves to enhance the environmental audit system of Bridgestone’s manufacturing facilities by regularly conducting system audits (mainly organizational audits) and performance audits (mainly based on performance data). Bridgestone also conducts internal audits based on the ISO 14001 standard and undergoes external audits, as well as carrying out regular training for internal environmental auditors.

Bridgestone requires all manufacturing sites with 50 employees or more to acquire ISO 14001: 2015 environmental management certification. Achieving this certification indicates that operations are continuously working to minimize their impact and comply with applicable environmental laws and regulations. At the end of 2024, all 96 required sites had obtained ISO 14001 certification.

Bridgestone’s ratio of sites with ISO 14001 certification is verified by LRQA Limited, a third-party institution promoting information transparency.

Bridgestone’s global environmental management structure comprises three meeting bodies: the Global Sustainability Committee (GSC), the Global Environment Working Group (WG), and strategic business units (SBUs). These coordinate with each other to enhance TEAMS activities in line with the mid-term plan. Bridgestone’s overall environmental strategies and policies related to the mid-term strategy on sustainability, including climate change, the circular economy, and nature-related issues are discussed at GSC meetings. The progress of activities and other issues are summarized and reviewed by the Global Environment WG, the GSC, etc., and reported to the Global Executive Committee (Global EXCO) under the management of Global CAO (Chief Administration Officer)・Global CSO (Chief Strategy Officer), which is held four times a year. The results of discussions at Global EXCO meetings are also presented to the Board of Directors, and approved strategies and policies are implemented by each SBU through the EMS.

Bridgestone established the Global Environment WG, which consists of members representing the environmental departments from each region, to strengthen coordination of its global and regional environmental activities.

Global Management Structure (As of January 2025)

Bridgestone has adopted a proprietary factory production qualification system based on the ISO 14001 standard to rapidly identify and minimize environmental risks at new factories and production lines.

When launching a new factory, Bridgestone uses this system to audit and certify the environmental management system stage by stage for formulating environmental plans, performing a preliminary environmental review when building a new factory or production lines, preparing environmental policies, ensuring legal compliance, and conducting environmental training programs.

Each of Bridgestone’s manufacturing facilities carries out environmental activities based on the ISO 14001 standard using a PDCA cycle under the leadership of senior management. Bridgestone also works to reduce the environmental footprint of each facility by reducing and controlling pollutants emitted into the water and air. This is achieved by designing processes to minimize waste generation and properly managing the waste that is generated. To do so, it secures the necessary number of personnel tasked with reducing these environmental risks and properly managing the relevant facilities. As one of its measures, Bridgestone has established Global Environmental Standards outlining the necessary requirements for facilities to minimize environmental impacts.

In addition, Bridgestone has prepared emergency response procedures based on the ISO 14001 standard and conducts scheduled drills to verify their effectiveness. It regularly reviews these procedures to make sure that plant production can be stopped and restarted without causing environmental problems in the event of disasters, such as a major earthquake.

Bridgestone has established a Global Environmental Standard for EMS that stipulates the minimum EMS elements that should be followed to achieve the intended outcome. Bridgestone will apply this standard to all Bridgestone Group sites that have not obtained ISO 14001 certification.

Bridgestone developed a Global Sustainable Procurement Policy to promote environmentally responsible business throughout the supply chain.

Bridgestone is monitoring and rating the environmental and social performance and governance (ESG) of its suppliers using third-party assessments as a tool to encourage suppliers to enhance their ESG commitment. ESG issues^*, which are assessed and linked to the Sustainable Procurement Policy, include environmental aspects such as energy consumption, water, biodiversity, pollution, and waste. Bridgestone holds sustainable procurement seminars and provides on-site support based on the assessment results and works together with suppliers in their environmental activities.

Bridgestone is an active member of the Japan Business Initiative for Biodiversity, which promotes environmental conservation. As a member of this organization’s working group (consisting of various businesses), Bridgestone is involved in researching effective ways to implement business-led policy measures to conserve biodiversity by reducing the impacts of the supply chain, and to visualize environmental impacts.

For more information on Bridgestone’s commitment to sustainable supply chain procurement, see “Procurement.”

* The ESG issues evaluated by Bridgestone include energy consumption, water, biodiversity, pollution, waste, customer safety, labor safety, labor practices, human rights, corruption, bribery, fraud, money laundering, and sustainable procurement.

Bridgestone requires all of its raw materials and component suppliers to comply with their respective national and regional regulations on the use of hazardous substances and materials. It also requires suppliers to eliminate the use of chemical products from the early stages if any hazardous substances are suspected in such products.

Prior to purchasing major components from suppliers, Bridgestone conducts an environmental management review of suppliers based on its outsourcing authorization system. In this review, it examines suppliers’ overall environmental management and programs. In addition to checking suppliers’ management systems for chemical products, Bridgestone also checks their systems for managing air, water, noise, vibration, odor, and industrial waste. If any item requiring improvement is identified, it notifies the supplier of the issue and asks them to make the needed improvements. Additionally, prior to purchasing new production equipment, Bridgestone requests suppliers to include information on the use of any hazardous substances in the equipment in their quotation.
