Environment | Reduce CO₂ emissions
Contributing to CO₂ reductions across the value chain

Given the emergence of climate change as a major global issue, Bridgestone perceives that interest in and demand for CO₂ reduction from society and customers will continue to grow. Aiming to achieve both business growth and CO₂ reduction (decoupling), Bridgestone has set carbon neutrality as its long-term environmental vision for 2050 and beyond. In line with this goal, Bridgestone is pursuing activities focused both on expanding its contribution to CO₂ reduction and on minimizing CO₂ emissions. With regard to CO₂ reduction in particular, Bridgestone aims to set itself apart and hone its competitive edge by providing solutions that draw on Dan-Totsu products and services, while also contributing to CO₂ reduction across the lifecycle, from raw materials procurement and distribution to customer use, reuse, and recycling.

Based on this approach, Bridgestone established its mid-term targets in 2020, known as Milestone 2030. It set a goal of contributing to CO₂ emissions reduction across the lifecycle and value chain (Scope 3^*1) of its products, services, and solutions at a level that exceeds five times the CO₂ emissions (Scope 1 and 2^*1) of its production activities by 2030^*2.

Bridgestone has established “CO₂ reduction contribution” as an indicator for measuring the extent of its contribution to CO₂ emissions reduction. In addition to reducing total Scope 1, 2, and 3 CO₂ emissions, the company evaluates the amount of CO₂ emissions avoided in society when older products and services are replaced with those that support CO₂ reduction. This assessment references the concepts in the WBCSD’s Guidance on Avoided Emissions v2.0 while reflecting the unique characteristics of Bridgestone’s businesses. The year 2020 serves as the benchmark for calculating the positive effect of CO₂ emissions reduction achieved through Bridgestone products, services, and solutions. Using this approach, Bridgestone quantifies its CO₂ reduction impact by combining improvements in environmental performance with the level of adoption of these offerings in society, and it uses these results to manage progress across various initiatives.

Bridgestone will continue to accelerate the development and broader adoption of its products, services, and solutions that support CO₂ reduction while also working to visualize its contribution to such reduction.

1. Emissions from production sites excluding discontinued operations. 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.
2. Base year: 2020

Bridgestone’s contribution to CO₂ reduction in 2025 increased to the equivalent of 3.2 times its own CO₂ emissions (Scope 1, 2). This progress reflects contributions from several areas, including “new premium” products equipped with ENLITEN, Bridgestone’s foundational product-design technology that reduces weight and improves wear resistance; lower rolling resistance in Dan-Totsu premium tires; expanded use of retreads; and the proposal of optimal routes through mobility solutions such as Webfleet and Azuga. To meet customer expectations for CO₂ reduction, Bridgestone supports lower emissions during driving by reducing rolling resistance at the product planning and design stage, which contributes to improved fuel economy and electricity consumption. In addition to expanding its contribution to CO₂ reduction, Bridgestone will contribute to such reduction across the entire lifecycle of its tires, including lowering CO₂ emissions during tire production to reduce the overall carbon footprint of its products.

Looking at the entire lifecycle of a tire, CO₂ emissions during product use account for the largest proportion, approximately 90% of the total emissions. As a provider of products and services that help reduce emissions during customer use, Bridgestone is developing and expanding fuel-efficient tires equipped with ENLITEN, an innovative tire technology that enhances both environmental and driving performance, along with mobility solutions that provide fleet management services.

In 2025, Bridgestone continued to reduce CO₂ emissions during vehicle operation through mobility solutions that lower tire rolling resistance. Combined with contributions across the entire value chain, these efforts resulted in an emissions-reduction impact equivalent to approximately 5.5 million tons^*2, which is 3.2 times the amount of CO₂ emissions generated by its production activities.

Bridgestone will continue to enhance the monitoring of its CO₂ reduction contributions from each SBU to further expand its overall emissions-reduction activities.

Bridgestone continues to expand its portfolio of mobility solutions, including fleet management services that leverage mobility and tire data from approximately 1.2 million contracted vehicles. This data is connected primarily through Webfleet Solutions in Europe and Azuga in North America and is used to generate business insights and create new value for fleet customers. In 2022, Webfleet Solutions partnered with the German startup Chargylize to support fleets in their transition to EVs. By analyzing vehicle data to recommend the EV models best suited to customer needs, and by supporting optimal operations in areas such as electric fleet management and EV charging solutions, Bridgestone aims to help advance a carbon-neutral mobility society from the ground up.

Webfleet Solutions contributes to CO₂ reduction through proposals for optimal operating routes for mobility. It enhanced its CO₂ reporting tool in 2024 to provide more comprehensive and actionable insights. Certified by TÜV Rheinland, this tool now allows fleets to report on both direct (Scope 1) and indirect (Scope 2) emissions using distance- and fuel-based calculations. This enables all Webfleet customers to consistently track emissions, regardless of vehicle type. The tool offers real-time and historical data, helping fleets comply with the EU's new Corporate Sustainability Reporting Directive (CSRD). It separates direct emissions from internal combustion vehicles and indirect emissions from electricity consumed by electric vehicles, automatically calculating carbon dioxide equivalents (CO₂-eq) in line with Greenhouse Gas (GHG) protocol guidelines.

In its tire-centric solutions business for trucks and buses, Bridgestone is working to establish a circular business model that maximizes tire value throughout its lifecycle. This model fully utilizes each tire through an integrated approach that combines Dan-Totsu products and retreads. A key element is expanding the lineup of products equipped with ENLITEN, which supports a high level of customization. With these durable, wear-resistant tires as a foundation, Bridgestone aims to increase the number of retreads per tire, contributing to improved resource productivity and reduced CO₂ emissions. In 2025, Bridgestone reduced CO₂ emissions at the raw materials stage by approximately 60 thousand tons through its retread business.

Tirematics, a digital tool for monitoring tire pressure and temperature, further supports safe driving and stable vehicle operation. Introduced in Europe in 2012 and now offered globally with enhanced service features, Tirematics help reduce environmental impact by preventing decreases in fuel efficiency caused by low tire pressure, thereby lowering CO₂ emissions during vehicle operation.

In 2025, the contribution to CO₂ emissions reduction from mobility solutions was equivalent to approximately 540 thousand tons.
