The Bridgestone Group offers revolutionary solutions that contribute to CO2 reductions by customers and partners across society. To accelerate its contributions, the Group sets 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.

  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, and after-use of lifecycle stages.

Tire technologies

Improving tire rolling resistance

Tire-rolling resistance coefficient

When a vehicle is in motion, a variety of factors are working against it, including air resistance and tire rolling resistance, all of which increase fuel consumption. Minimizing these resistance factors enables the vehicle to use less energy and leads to improved fuel efficiency.

The Group achieved a 24% reduction in tire rolling resistance compared to 2005 in 2020 (equal to a contribution of approximately 12.0 million tonnes CO2 reduction*1). The Group will continue to expand our contribution to CO2 reduction by reducing rolling resistance. Improving rolling resistance and maintaining safety at the same time is a difficult task that requires innovative technologies. Bridgestone developed NanoPro-Tech™*2 technology and promotes sales of fuel-efficient tires utilizing this technology around the world to help reduce CO2 emitted during use.

Development of fuel efficient tires

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 as a way 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 3,000km (1,860miles) 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 impacts while supporting young engineers.

Technology that achieves both environmental benefits and driving performance: ENLITEN

ENLITEN technology makes it possible to reduce the weight of tires by approximately 20% and rolling resistance by approximately 30%*1 compared to conventional passenger car tires. It achieves these benefits by reducing the number of components used in tires, while maintaining driving performance and tire life. This makes it possible to reduce CO2 emissions caused by tires by about 30% when driving gasoline-powered vehicles. It also contributes to reducing environmental impact and the achievement of sustainable mobility by extending the driving range of electric vehicles (EVs) on a single charge. It further contributes to improved resource productivity by reducing total material weight.

This cutting-edge technology has been driven by the EMIA Region (Europe, Middle East, India and Africa) and in order to enhance and continuously improve the product stewardship, the R&D located in Rome, Italy, and having in its scope the design and development of products for the EMIA Region obtained since 2002 the ISO14001 certification for such crucial phase in the value chain.

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 reduce further rolling resistance and increase the driving range of electric vehicles. This co-creation between Lightyear and Bridgestone 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.

Fleet Solution: the WEB-FLEET service

The WEBFLEET service from the Group's Webfleet Solutions business supports transportation operation and contributes to improved safety, efficiency and productivity of drivers and operators by managing various data related to vehicle operations. The Group also contributes to improved fuel efficiency and reduced CO2 emissions by streamlining operations. To date, 900,000 vehicles have used WEBFLEET.

By combining vehicle operations data with the Bridgestone Group’s knowledge of tire wear and durability, it can provide a wider range of solutions, including products and services based on customers’ unique operating conditions and needs. Additionally, data on vehicle operating and tire usage conditions is being deployed by R&D teams to more rapidly develop high-quality tires that meet customers’ evolving needs.

Diversified products with high green performance

Vortech® rubber tracks for low fuel consumption

Vortech® rubber tracks are a new generation of low fuel consumption rubber tracks that help reduce the carbon emissions of Vortech®-equipped construction machineries.

Developed by Bridgestone, Vortech® rubber tracks have been designed to provide the same or higher levels of durability and other standard performance as similar products in its class using an optimized internal structure and tread pattern. This dramatically lowers the bending resistance that occurs when rubber tracks rotate, leading to less drive loss and contributing to improved fuel consumption, more fluid vehicle movement and better work efficiency.*1

Flame-retardant, energy-efficient conveyor belt

Using rubber material technology cultivated through the development of the ECOPIA fuel-efficient tires, Bridgestone Group offers flame-resistant conveyor belts that add further capacity to save energy worldwide.*1

The most significant source of energy loss from belt conveyor operation is produced by resistance when the belt travels across rollers (roller crossing resistance). By focusing on this roller crossing resistance and using newly developed rubber materials from the tire business, the Group succeeded in developing a conveyor belt designed to save energy while maintaining flame resistance. It offers this innovative product as a cost-saving solution at mines, ports, power plants and other facilities. The Group plans to develop this product to meet the needs of an even broader base of customers.
