CO2 emissions reduction in operations | Reduce CO2 emissions | Environment | Sustainability

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 2025, Bridgestone continued its efforts to improve energy efficiency and introduce renewable energy sources, achieving its 2026 interim target with a 63% reduction compared to 2011, which also exceeds its 2030 milestone. The significant decline was due to ongoing improvements in energy efficiency through energy conservation activities and steady progress in switching to electricity derived from renewable energy and low-carbon fuels. By moving ahead while considering the balance with our businesses, we also improved carbon productivity in 2025 to 2.7 times that of 2021.

The basic structure of the transition plan toward carbon neutrality is shown in the above image. First, the plan assumes the optimization of energy consumption through improved productivity and energy efficiency. Bridgestone will also move forward with the transition by drawing on its core value-creating technologies, such as ENLITEN technology, to differentiate products in conjunction with BCMA technology to simplify production. BCMA in particular supports module sharing across product lines, which helps lower production costs while also achieving reductions in energy consumption and CO₂ emissions associated with material changes. 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 four 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, the I-REC (International Renewable Energy Certificate) program, 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 Bridgestone (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.

Bridgestone is enhancing its Milestone 2030 and supplier engagement initiatives to realize carbon neutrality and a circular economy as well as to advance the Sustainability Business Framework, which ensures the link between sustainability activities and businesses across the value chain. Furthermore, Bridgestone is also advancing initiatives toward nature positive within its value chain, thereby evolving its business model into one that is more circular and regenerative.

To accelerate these initiatives, in January 2023 Bridgestone obtained approval from the Science Based Targets initiative (SBTi), which noted that its CO₂ reduction targets for 2030 are consistent with the level stipulated in the Paris Agreement (holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels).

The following near-term targets were approved by SBTi:

Bridgestone Corporation commits to reduce absolute Scope 1 and 2 GHG emissions 28% by 2030 from a 2019 base year.^*
Bridgestone Corporation commits that 92% of its suppliers by emissions (covering purchased goods and services) will have science-based targets by 2026.

* The target boundary includes land-related emissions and removals from bioenergy feedstocks.

ISO 50001 certificate of San Jose Plant

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’s Nong Khae Plant in 2015, Bridgestone (China) Investment’s Wuxi Plant in 2021, and Bridgestone de Costa Rica’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.

As part of its efforts to achieve carbon neutrality, Bridgestone is striving to expand the introduction of renewable energy in various regions. In Europe in particular, given the well-established renewable energy supply environment in the region, from early on, Bridgestone has pursued the switch to renewable energy and has expanded the use of renewable energy for purchased electricity. By the end of 2022, it had switched 100% of purchased electricity used at all Bridgestone Europe NV/SA (BSEMEA) production sites^*1 to renewable energy. Meanwhile, in its Japan, Asia, Pacific, India, China, and Americas businesses, because the liberalization of electricity markets and the diffusion of PPA schemes differ between countries and regions, Bridgestone is steadily raising its renewable energy ratio by combining easily procurable renewable energy certificates and other methods with on-site power generation^*2 at its plants. All Bridgestone Corporation plants in Japan had switched to renewable energy for purchased electricity by the end of 2024.

In addition to switching to renewable energy for purchased electricity, Bridgestone is focusing on the roll-out of on-site power generation from the perspective of strengthening sustainable renewable energy procurement and introducing electricity with high environmental value. When considering how to introduce on-site generation, Bridgestone seeks to capitalize fully on private power generation equipment and on-site power purchase agreements (PPAs), taking into account differences in regulations and the feasibility of installation in various regions.

Furthermore, Bridgestone is moving ahead with the introduction of renewable energy at non-manufacturing sites. At its technology centers in Italy and Thailand, Bridgestone has switched all purchased electricity to renewable energy, and in Japan, at the technology center in Tokyo, it has switched the majority of purchased electricity to renewable energy. Bridgestone has also installed solar power generation systems at its Chemical & Industrial Products Technology Center in Yokohama and at its B-Trinity building and B-Innovation sites in Tokyo to generate power on-site.

As a result of these initiatives, by the end of 2025, Bridgestone had completed the transition to 100% renewable energy-derived or low-carbon energy sources for purchased electricity at 63 manufacturing plants globally. Furthermore, Bridgestone exceeded its target of expanding the renewable energy (electricity) ratio^*3 to over 70% by 2026, with the ratio reaching 73.5% in 2025. On-site power generation accounts for 3.1% of this total, with annual on-site generation increasing 2.5 times compared to the end of 2023, prior to the start of the 24MBP Mid Term Business Plan. This has helped to reinforce business quality through the optimization of electricity costs. Moving forward, Bridgestone will continue to roll out and optimize renewable energy in each strategic business unit, taking regional characteristics into account.

Bridgestone utilizes steam in its tire manufacturing processes, using natural gas and other fossil fuel-based energy. There are generally three approaches to reducing CO₂ emissions (Scope 1) generated from the use of such fuels:

- Switching fuels (changing from fossil fuels to non-fossil fuel)
- Electrification (converting production processes that use steam to processes powered by electricity sourced from renewable or clean energy)
- CO₂ capture and reuse

The type and price of energy available for use vary by region, but Bridgestone to date has mainly pursued approaches based on fuel switching and electrification, aiming to achieve both reductions in Scope 1 CO₂ emissions and cost savings.

Installation of Biomass Boilers

As one of its initiatives for reducing Scope 1 CO₂ emissions in consideration of regional characteristics, Bridgestone is promoting the conversion of energy sources for heat.

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 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 in 2023. This transition is expected to reduce CO₂ emissions by approximately 92% compared to the emissions produced by the LPG boiler.

* Except during maintenance

To reduce Scope 1 CO₂ emissions, Bridgestone uses electric boilers in regions where the renewable energy ratio of grid electricity is relatively high and the CO₂ emissions factor of electricity is low.
At the Joliette Plant in Canada, early electrification (the introduction of an electric boiler since 2012), a solar wall, and a proactive utility partnership are turning incentives into impact—cutting on-site combustion and accelerating Scope 1 decarbonization.

The San Jose Plant in Costa Rica installed a similar boiler in 2023, powered by Costa Rica’s clean hydropower electricity. The electric boiler now works in tandem with the site’s biomass boiler to supply low-carbon steam for the manufacturing process at a cost benefit to the plant. The Bahia Plant in Brazil completely replaced its conventional fossil fuel boiler with an electric boiler in 2024, in addition to introducing on-site solar power generation.

Bridgestone has also installed electric boilers for the steam used at its technology center and pilot plant in Rome.

At the Burgos Plant in Spain, a heat pump recovers waste heat from the mixing and extruding cooling system and uses it to heat the plant. Since the electricity that powers the heat pump is supplied from renewable energy, this approach contributes to the reduction of Scope 1 emissions.

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, its 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. Under Milestone 2030, it aims to improve energy efficiency by 0.5% per year and will continue to promote these activities throughout the Group.

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 operations’ CO₂ emissions (Scope 1 and 2) by 2030 (base year 2020). In 2025, Bridgestone continued to reduce CO₂ emissions during vehicle operation and mobility solutions. As a result, the contribution to CO₂ emissions reduction was equivalent to approximately 5.5 million tons.^* This is 3.2 times the amount of CO₂ emissions from operations.

Bridgestone will continue to improve the monitoring of its CO₂ reduction contributions of each SBU to expand its overall CO₂ reduction activities.
