The Bridgestone Group set the focused target towards 2030: contributing to global CO2 emissions reduction across the lifecycle and value chain (Scope 3*1) of its products and services exceeding five times its operation’s (Scope 1 and 2*1) CO2 emissions*2. The Group seeks to differentiate itself and strengthen its competitiveness by providing solutions based on Dan-Totsu (the clear and absolute leader) products and services, helping its customers reduce their CO2 emissions and become carbon neutral.

  1. Scope 1 covers all direct CO2 emissions by a company (from boilers of manufacturing facilities, etc.). Scope 2 covers indirect energy-related CO2 emissions (from consumption of purchased electricity, etc.). Scope 3 covers CO2 emissions from raw material procurement, distribution, customers’ use, disposal, and recycling lifecycle stages.

Tire technologies

Expanding contribution to CO2 reduction

Looking at the entire lifecycle of a tire, CO2 emissions during product use account for the largest proportion, approximately 90% of the total*1. As a provider of products and services that contribute to the reduction of CO2 emissions from customer use, the Group is developing and expanding fuel-efficient tires equipped with ENLITEN, an innovative tire technology that combines environmental and driving performance, and mobility solutions that provide fleet management services.

In 2021, the Group continued to reduce the tire rolling resistance, and the contribution to CO2 reduction combined with the activities of the entire value chain is equivalent to approximately 1.6 million tons*2. This is 0.5 times the amount of CO2 emissions from its operations. The Group will continue to improve its monitoring of the amount of CO2 reduction contribution of each SBU and expand its contribution to CO2 reduction.

The Bridgestone Group develops and sells various environmental products that meet the diverse needs in its core business. The Group promotes lightweight, fuel-efficient tires with low rolling resistance and high wet grip performance led by the ECOPIA brand to mitigate climate change through greater vehicle fuel economy.

Entirely new tire technology: ologic

The Bridgestone Group's improved fuel economy tire technology “ologic” realizes superior performance through the following two features:

(1) The tire’s large diameter and high internal pressure (high inflated air pressure) significantly reduce tire deformation from contact with the road surface and lower rolling resistance.

(2) The tire’s narrow tread design lowers air resistance, an important factor linked to improved vehicle fuel efficiency.

Further, by optimizing the material, structure and pattern of the rubber and reinforcement layers, the Group was able to reduce the rolling resistance coefficients by approximately 30% compared to conventional standard tires. At the same time, safety is enhanced by improving vehicle handling on wet road surfaces by approximately 10%*1.

ECOPIA with ologic tires, which employ ologic technology, are standard equipment on the BMW i3 revolutionary electric vehicle. They are also used on solar cars participating in the Bridgestone World Solar Challenge, the world’s top solar-powered car race.

While reducing CO2 emissions during the production process, the Bridgestone Group also aims to reduce CO2 emissions during tire use, through technological development and global sales of more fuel-efficient tires to improve vehicle fuel economy.

Support of Bridgestone World Solar Challenge (BWSC)

The BWSC is the world's foremost solar car race, which travels 3,000 km (1,860 miles) from Darwin to Adelaide in Australia. It started in 1987 with the purpose of contributing to the development of solar cars, supporting young engineers, and contributing to the environment through the use of solar power. Participants are challenged to design, build and develop the world's most efficient vehicles. In addition to supporting the competition as a title sponsor, Bridgestone supplies “ECOPIA with ologic” tires to participating teams, contributing to the mobility of society and reducing environmental impact while supporting young engineers.

Technology that achieves both environmental benefits and driving performance: ENLITEN

To respond to this evolution in mobility and the need for sustainability, the Group has strengthened development of ENLITEN as the innovative tire technology optimized to fit electric vehicles and expanded from the fitment on tires for new vehicles in Europe. ENLITEN is a core element of the strategy to strengthen the Bridgestone Group’s Dan-Totsu Products. The considerable reduction in tire weight and rolling resistance, longer wear life per raw material and retreading help to conserve resources and lowers the environmental impact, while also extending an electric vehicle’s range with tire technology that achieves balance of various performances such as driving performance and durability. Up to now, this had been considered a trade-off.

Going forward, the Group will enhance value in its products and business model as part of the ENLITEN business strategy. The Group will establish a new premium strategy for the EV era by providing customized tire performance for individual customers. At the same time, it will create value by enhancing productivity throughout the value chain and optimizing costs. Key to this initiative is pursuing innovation in the development and production process as well as establishing links with commonality and modularity to enable simplification and differentiation. Doing so will reduce the Group’s environmental load and drive business growth.

Supporting the widespread adoption of EVs with ENLITEN

The Group is expanding the use of ENLITEN for tires on new electric vehicles in its Europe focus area. Approximately half of the ten most popular models of electric vehicle sold in Europe in 2021*1 were fitted with Bridgestone Group tires. The Group’s development facilities in Europe are accelerating innovation and expansion of ENLITEN, with more than 30% of resources devoted to tires for electric vehicles. The Group has set a target for ENLITEN equipment for 10% of the replacement tires on passenger cars in Europe by 2023, rising to 70% by 2024, and to more than 90% by 2030.

ENLITEN technology is applied on Turanza Eco tires specially engineered for Lightyear One, the world’s first long-ranged solar electric vehicle by Netherlands-based mobility innovator Lightyear*2. The Bridgestone Group developed the Turanza Eco tires by combining, for the first time, the revolutionary lightweight ENLITEN and ologic technology, which has larger diameters, high-inflation pressures and slim design. The technologies made it possible to further reduce rolling resistance and increase the driving range of electric vehicles. This co-creation between Lightyear and the Group is a direct result of a shared focus on sustainability and a relationship built upon the more than eight years of collaboration through the Bridgestone World Solar Challenge. The development of Turanza Eco tires is a step up to a new stage of this co-creation activity based on technological innovation.
