Reducing CO2 emissions (Scope 1 and 2) in manufacturing and Transition Plan
To achieve its goal of realizing carbon neutrality by 2050, Bridgestone has set a target for Milestone 2030 to reduce its absolute CO2 emissions (Scope 1 and 2*) by 50%, compared to 2011. Bridgestone has also set an interim goal of reducing Scope 1 and 2 emissions by 50% or more by 2026 compared to 2011 ahead of Milestone 2030.
In 2024, Bridgestone continued efforts to improve energy efficiency and introduce renewable energy sources, achieving its 2026 interim target with a 62% reduction compared to 2011, which also exceeds its 2030 milestone.
In 2024, Bridgestone set a new interim target for 2026 of over 50% reduction compared to 2011, while expanding its production and sales volume. For more information on the Mid Term Business Plan, please refer to the Investor Relations page: "Mid-Long Term Business Strategy.”
In 2023, Bridgestone’s Pune plant in India was verified as its first carbon neutral (scope 1 and 2) tire manufacturing site. The Pune manufacturing facility produces more than 4 million tires per year. Over the years, the site has reduced its total carbon footprint by 94% through a number of measures. These include solar panels at the plant, I-REC (International Renewable Energy Certificate) and a carbon neutral biomass-based boiler which uses carbon neutral biomass briquettes made from agricultural waste. As part of its PAS 2060 verification, the site has committed to a further CO2 reduction plan for the next three years.
* The target covers emissions from production sites excluding discontinued operations. Scope 1 covers all direct CO2 emissions by the 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.
In May 2012, Bridgestone Europe Technology Center in Rome achieved the first ISO 50001 certification (energy management system certification) in Italy. Bridgestone Europe, Middle East and Africa (BSEMEA) has been focusing on enhancing energy management. With the ISO 50001 certification of the Britz plant in South Africa in 2024, certification is now complete at all tire manufacturing plants in BSEMEA, and the Technology Center and Proving Ground in Italy. In addition, certification was obtained by the plants in Izmit and Aksaray (Turkey) and the Pune and Indore plants in India. Other certifications include Thai Bridgestone Co., Ltd.’s Nong Khae plant in 2015, Bridgestone (China) Investment Co., Ltd.’s Wuxi plant in 2021, and Bridgestone de Costa Rica S.A.’s San Jose plant in 2018.
Bridgestone is working to improve energy management by identifying the major causes of excess 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 toward carbon neutrality, Bridgestone is expanding its use of renewable energy sources at manufacturing and other facilities, including non-manufacturing sites. As of 2021, Bridgestone had transitioned all electricity purchased to renewable energy sources at all of BSEMEA’s Europe locations, four plants in Japan (Hikone, Shimonoseki, Tosu, and Kitakyushu), and two plants in China (Tianjin and Wuxi). In EMEA, sites have been 100% covered with renewable electricity since 2023. 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 the Americas, at the beginning of 2023, two plants (Monterrey and Cuernavaca) transitioned to carbon-free energy, while 70% of the electricity consumed at the Buenos Aires plant is now from renewable energy. By 2024, 14 tire plants in Japan and 11 plants of group companies in Japan had completed the transition to purchasing renewable energy.
Chonburi plant (Thailand)
Wuxi plant (China)
Aiken plant (United States)
In addition to switching to renewable energy sources for purchased electricity, Bridgestone is also focusing on introducing solar power generation equipment from the perspective of reducing costs and introducing electricity with high environmental value. In 2018, the Wuxi Plant (China) and in 2019 Pune Plant (India) began using electricity generated by large-scale solar power panels installed on the facilities’ roofs by electricity suppliers. In 2019, Bridgestone commissioned a 1.725 MWp solar installation at the Indore (India) plant. This resulted in a reduction of 1,601 MT of CO2 emissions along with an annual cost saving of approximately Rs. 6.874 million (approx. US$83,000). The Chonburi plant in Thailand installed 2,160 solar panels on its roof and started supplying 1MW of solar power in 2021. Solar rooftop panels were installed at the Nong Khae plant in 2022. With the largest solar rooftop panel capacity among Group sites, at a total of 9.95 MWp, this site is expected to create a 97,500-ton reduction in total CO2 emissions over the next 15 years.*1 Also, in 2020, a 2MW solar power system was installed at the Aiken Passenger/Light Truck Tire plant in the United States and, in 2022, a large 9.2 MW solar power system began operation at the Burgos plant in Spain. In addition, Bridgestone is introducing renewable energy at its non-manufacturing sites and has switched all electricity to renewable energy at its research center in Thailand. In Japan, the Chemical & Industrial Products Technology Center (Yokohama), and the Global-Manufacturing Education Center and B-Innovation (Tokyo) have each introduced solar power generation systems.
In Japan, Bridgestone has commenced solar power generation under power purchase agreement (PPA) at eight of its tire manufacturing plants (Shimonoseki, Kitakyushu, Kurume, Amagi, Hikone, Tosu, Nasu, and Saga). The total generation capacity is 12.8 MW, supplying electricity to these eight plants and contributing to an annual reduction of approximately 7,400 tons of CO2 emissions (Compared to grid electricity*2).
In 2023, wind power generation commenced at the Bridgestone Aircraft Tire (EUROPE) plant in Belgium based on a power purchase agreement.
As a result of these initiatives, as of the end of 2024, 64 Bridgestone sites have switched to electricity derived from 100% renewable energy or low- CO2 power sources. The renewable energy ratio (electricity) in Bridgestone reached 75% in 2024*3, which exceeded the 2026 target of expanding the use of such energy by more than 70%. Bridgestone will continue to promote the introduction of renewable energy , while considering the local characteristics of each SBU (Strategic Business Unit).

Transition to renewable energy sources (fuel)
Installation of Biomass Boilers
As one of the initiatives for Scope 1 CO2 emissions reduction in consideration of regional characteristics, Bridgestone is promoting the energy source conversion of heat.
Energy efficient biomass boiler
Wood pellet biomass fuel
Hai Phong plant (Vietnam)
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 its goal of carbon neutrality.
In addition, the Bridgestone India Private Limited Pune plant installed a biomass boiler in 2021 to cover 100% of the plant’s steam demand. Bridgestone Tire Manufacturing Vietnam in Hai Phong shifted to 100% renewable energy from biomass for steam used in production. This transition is expected to reduce CO2 emissions by approximately 92% compared to the emissions produced by the LPG Boiler.
Electric boilers are also used in regions where the renewable energy ratio of grid electricity is relatively high and CO2 emissions factor of the electricity is low, in order to reduce Scope 1 CO2 emissions. The San Jose plant (Costa Rica) installed such a boiler in 2023, and the Bahia plant (Brazil) also installed one in 2024.
Group-wide survey to identify energy losses

Even as manufacturing volumes grow in response to demand, Bridgestone will continue to work to reduce its energy consumption to achieve its 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. Bridgestone is also continuously developing the ability of its employees to recognize and implement energy-saving opportunities. In Milestone 2030, it aims to improve energy efficiency by 0.5% per year, and will continue to promote these activities throughout the Group.
Reducing Scope 3 CO2 emissions from raw materials, distribution and after-use
In Milestone 2030, Bridgestone set a target to reduce CO2 emissions throughout 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 2024, the contribution to CO2 emissions reduction, combined with the activities of the entire value chain, was equivalent to approximately 4.8 million tons.* This is 2.9 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.
CO2 emissions reduction at logistics facilities in Japan
Promoting modal shift between the Kanto and Kyushu areas
As a large shipper, Bridgestone Corporation is working with logistics companies, including its affiliated company Bridgestone Logistics, to reduce annual CO2 emissions per energy intensity by 1% on average. For trucks and cars, the Company adopted hybrid and other low-emission vehicles, introduced eco-driving guidance, and increased the size of vehicles to enhance transportation efficiency. It also expanded the round-trip use of containers and vehicles by reducing the return of empty containers and using a comprehensive vehicle allocation system to shorten shipping distances by improving logistics routes. The Company is also working to reduce CO2 emissions associated with shipping from plants to distribution centers through modal shifts, such as switching to rail and ship transportation.
