ISO 50001 certification

ISO 50001 certificate of San Jose Plant

In May 2012, Bridgestone Europe Technology Center in Rome was the first to acquire ISO 50001 certification in Italy. Bridgestone Europe, Russia, Middle East, India, and Africa (BSEMIA) has been focusing on enhancing energy management, acquiring ISO 50001 certification for all of its tire plants in Europe by 2020. In addition, the certification was obtained by the plants in Izmit and Aksaray (Turkey). Other examples of certification acquisition include Thai Bridgestone Co., Ltd. in the Rangsit Plant and in the Nong Khae Plant in 2015, Bridgestone (China) Investment Co., Ltd. in the Wuxi Plant in 2021, and Bridgestone de Costa Rica S.A. in the San Jose Plant in 2018.

The Group is working to improve energy management by identifying the major causes of energy consumption, defining effective indicators, implementing continuous monitoring in real time (as per the “Smart Energy” project in Europe), setting targets, promoting awareness among employees, improving the skills of technicians involved with equipment and engaging in initiatives including forming specialized energy conservation teams.

Transition to renewable energy sources (electricity)

As part of its efforts towards carbon neutrality, the Group is expanding its use of renewable energy sources at manufacturing and other facilities including non-manufacturing sites. In 2021, the Group has transitioned all electricity purchased to renewable energy sources at all of BSEMIA’s Europe locations, four plants in Japan (Hikone, Shimonoseki, Tosu, and Kitakyushu) , two plants in China (Tianjin and Wuxi). In 2022, one plant in India (Pune), and two plants for diversified products in China (Shenyang and Changzhou) also switched to renewable energy sources for purchased electricity. In Japan, six tire and raw materials plants (Hofu, Tochigi, Nasu, Kurume, Amagi and Saga) transitioned all the electricity purchased to renewable energy sources and two chemical and industrial products plants (Seki and Kumamoto) have also began transitioning to renewable energy sources. The transitions are estimated to raise the renewable energy ratio (electricity) used at production bases in Japan to around 90%.*1

Chonburi Plant (Thailand)

The Chonburi plant in Thailand installed 2,160 photovoltaic panels on its roof and started supplying 1MW of solar power in 2021. Thai Bridgestone Co., Ltd. installed solar rooftop panels in the Nong Khae Plant in 2022. With the largest solar rooftop panel among the Group at a total capacity of 9.95 MWp, it is expected to generate a 97,500 tons reduction in total CO2 emissions over the next 15 years.*2 Also, a large 9.2MW solar power system is in operation at the Burgos plant in Spain in 2022. In addition, the Group is introducing renewable energy at its non-manufacturing sites and has switched all electricity to renewable energy at its research center in Thailand. At two tire plants in Japan, the Shimonoseki Plant and Kitakyushu Plant, solar power generation commenced based on a power purchase agreement. This is the first instance at a Bridgestone tire plant in Japan to engage in large-scale generation of solar power based on a power purchase agreement. With a combined generation capacity of 5.8 MW, the applicable solar power systems will supply the electricity used to produce tires at the two plants while contributing to an expected reduction in annual CO2 emissions of approximately 2,700 tons (in comparison to emissions from electricity supplied through the power grid*3).

Wuxi Plant (China)

Aiken Plant (United States)

Wuxi Plant (China) and Pune Plant (India) began using electricity generated by large-scale, solar power generators installed on the facilities’ roofs with electricity suppliers in 2018.

In addition, large-scale solar power generation (2MW) has begun operating at Aiken Plant (United States) in 2020.

In Japan, four Bridgestone Group tire manufacturing facilities (Tosu, Tochigi, Kitakyushu and Kurume), Chemical & Industrial Products Technology Center (Yokohama) and Global-Manufacturing Education Center, B-Innovation (Tokyo) have introduced solar photovoltaic power generation systems.

As a result of these initiatives, the renewable energy ratio (electricity) in the Group reached 26% in 2022. With the goal of expanding this ratio to more than 50% by 2023, it will continue to expand the introduction of renewable energy while considering the local characteristics of each SBU.

  3. Electricity handled through the power system used to generate electricity at power generators, transform this electricity, and transmit and distribute it to users.

Transition to renewable energy sources (fuel)

Energy efficient biomass boiler

Wood pellet biomass fuel

Bridgestone Costa Rica (BSCR) introduced a biomass boiler to produce heat for its San Jose Plant in 2014. The company successfully reduced CO2 emissions for the facility by approximately 50% by replacing oil with wood pellets as fuel for the boiler. This BSCR initiative is helping the Republic of Costa Rica achieve carbon neutrality.

In addition, Bridgestone India Private Limited Pune Plant installed and started to use Biomass boiler to cover 100% of the plant’s steam demand in 2021.

Group-wide energy survey to identify energy losses

Even as the manufacturing volumes grow in response to demand, the Group will continue to work to reduce its energy consumption to achieve the CO2 emissions reduction goals. Since 2009, Bridgestone’s Technology Center has proactively conducted energy surveys to identify energy losses and areas for improvement at plant facilities. The Group is also continuously developing the ability of the personnel to recognize and implement energy-saving opportunities. In Milestone 2030, the Group aims to improve our energy efficiency by 0.5% per year, and it will continue to promote these activities throughout the Group.

Reducing Scope 3 CO2 emissions from raw material, distribution and after-use

In Milestone 2030, the Group set a target to reduce CO2 emissions across the lifecycle and value chain (Scope 3) of its products and services exceeding five times its operation’s (Scope 1 and 2) CO2 emissions by 2030 (base year 2020). In 2022, the contribution to CO2 reduction combined with the activities of the entire value chain is equivalent to approximately 2.9 million tons*. This is 0.95 times the amount of CO2 emissions from its operations.

* Calculated using Bridgestone's proprietary calculation method based on the "Tyre LCCO2 Calculation Guidelines Ver. 3.0.1” (The Japan Automobile Tyre Manufacturers Association, Inc)Bridgestone’s CO2 emissions are verified by LRQA Limited, a third-party institution, to ensure the accuracy and transparency of this information.
