Long-term environmental vision (2050 and beyond): Towards 100% sustainable materials

An increase in the population and the number of automobiles will likely further boost tire demand in the future. Bridgestone is working toward its goal to minimize resource depletion by implementing sustainable resource use through promoting technological innovation and business innovation. Bridgestone has set the goal of using “100% sustainable materials” in its products as its long-term environmental vision for 2050 and beyond.

Bridgestone defines sustainable materials as those that:

(1) come from resources with a continual supply;
(2) can be used as part of Bridgestone's business over the long term; and
(3) have a low environmental and social impact over their lifecycle from procurement to disposal.

Bridgestone has established three main actions throughout its value chain to reduce, circulate (reuse and recycle) resources and widen and diversify renewable resources.

1. Reduce raw material consumption
   (Examples)
   ・Weight-saving technologies
   ・Durability improving technologies
   ・Reduction of manufacturing process losses
2. Recycle and effectively use resources
   (Examples)
   ・Retread technologies and solutions
   ・Recycled rubber and recovered carbon black
3. Expand and diversify renewable resources
   (Examples)
   ・Natural rubber productivity improvement technologies
   ・Diversified natural rubber supply sources (guayule)
   ・Development of bio-derived raw materials

Economic growth is expected to increase resource consumption and demand, thereby restricting resource supply and deepening issues of natural resource depletion and soaring resource prices. The smarter, more sustainable use of resources is important not only for addressing environmental issues, but also for society and Bridgestone’s businesses. A circular economy^*1 not only helps mitigate pressures on the environment, but it also provides an opportunity to transform Bridgestone’s business model to increase the business value of its tires and gain a competitive advantage by using resources more wisely and sustainably. To this end, Bridgestone is integrating circular economy concepts into its Sustainability Business Model. It is also making comprehensive efforts to contribute to the attainment of four important social and customer values: safety, environment, economy, and productivity.

Bridgestone contributes to the creation of a circular economy by designing and developing products and business models with high resource efficiency, using recycled and renewable resources (material circularity^*2) and accelerating comprehensive initiatives in the effective use of used tires (product circularity^*3).

To promote its contribution to a circular economy, Bridgestone has set a target to increase its ratio of recycled and renewable materials to 40% by 2030. It is accelerating various initiatives throughout the entire product lifecycle, such as long-life design, expansion and diversification of renewable resources, retreading, recycling, repairing, sharing, etc. Bridgestone achieved a 40.0% use of recycled and renewable resources in 2025, surpassing its target of 39% for 2026 ahead of schedule and reached the 2030 target level. The improvement indicates our transformation towards a business structure that can create business value with fewer resources. We will continue to move forward while balancing sustainability and the strengthening of our competitiveness.

Bridgestone's approach to the circular economy

In order to achieve “100% sustainable materials” in its products, Bridgestone is accelerating its efforts to use more recycled and renewable materials in specific products. Bridgestone is actively pursuing ISCC PLUS certification^*1. As of the end of April 2026, Bridgestone has obtained certification at 19 tire plants, four raw material plants, and one other site.

*1 ISCC PLUS certification is a certification system developed by ISCC (Sustainability and Carbon Certification). The certification applies to products that are linked to raw materials derived from renewable resources such as biomass, or recycled. And it also validates the sustainability characteristics of alternative feedstocks throughout the entire supply chain, from origin to end consumer. For more details about ISCC, please go to: https://iscc-system.org.

In May 2023, Bridgestone launched Turanza EV in North America, a tire for electric vehicles that uses 50% renewable and recycled materials. The 50% consists of 20% natural rubber, 18% recycled (circular) synthetic rubber, and the rest recycled (circular) carbon black. ISCC-certified circular butadiene rubber, styrene butadiene rubber, and carbon black are allocated using the ISCC mass balance approach.

In 2024, Bridgestone EMEA announced Potenza Sport A tire incorporating 55%^*1 ISCC PLUS certified recycled and renewable materials for use on the new Audi e-tron GT, Audi’s new EV. 35% ISCC PLUS certified renewable materials are sourced to produce the tire, including natural rubber and bio-attributed polymers, as well as 20% ISCC PLUS certified recycled materials^*. These include ground rubber linked to End-of-Life Tire, certified carbon black linked to circular oils, rice husk ash silica, lignin, zinc oxide, and recovered carbon black linked to End-of-Life Tire.

In Japan, Bridgestone launched REGNO GR-XIII in February 2024, which partially allocated synthetic rubber using the ISCC mass balance approach. In February 2026, Bridgestone launched ALENZA LX200^*2 (synthetic rubber, PET), POTENZA RE-71RZ^*2 (PET), and FINESSA HB01 (synthetic rubber), each partially allocated with the raw materials listed in parentheses the ISCC mass balance approach, contributing to the realization of a circular economy.

2. For the Japanese market

In motorsports, Bridgestone supplied tires with a higher ratio of renewable and recycled materials for the 107th Indianapolis 500 (held in May 2023) and the 2025 Bridgestone World Solar Challenge (BWSC, held in August 2025), the world's most prestigious solar car race.

At the Indianapolis 500, all race tires were produced using ISCC PLUS certified recycled butadiene, which is made from hard-to-recycle used plastic shopping bags, film, stretch wrap and other flexible polymer packaging.

At the 2025 BWSC, Bridgestone for the first time applied recovered carbon black and steel, recycled materials developed and produced through co-creation efforts focused on advanced recycling technology that ”renews” tires to raw materials. By utilizing other recycled and renewable materials as well, Bridgestone was able to supply ENLITEN technology tires with a recycled and renewable material ratio (MCN - Material Circularity Number) of over 65%, an increase of approximately 35% over the tires supplied for the 2019 BWSC event.
