Difference in CO2 emissions from operations and products’ after-use and contribution to CO2 reduction at the usage stage
To move toward the 2050 vision, the Bridgestone Group has established a primary 2020 mid-term target (Milestone 2020): reduced emissions footprint from customers’ use of Bridgestone tires will exceed the Group’s emissions from raw material procurement, product manufacturing, distribution and its products’ after-use. Combining the CO2 reductions from operations and products' in-use, the Group achieved the 100% reduction goal in 2019, in comparison with the 2005 baseline*1.

Milestone 2030: Reduce emissions across the product lifecycle and entire value chain
With decoupling in mind, the Bridgestone Group has set a goal to reduce its absolute volume of CO2 emissions from its own immediate production activities. In addition, the Group will accelerate its contribution to the reduction of CO2 emissions through products and solutions. In this way, the Bridgestone Group will pursue CO2 reductions throughout its product lifecycle and entire value chain.
Furthermore, previous environmental goals were based on intensity, or emissions reductions as a ratio of net sales. However, focusing solely on intensity could lead to CO2 emissions increasing in step with business growth in absolute terms, counteracting the work to battle climate change. Therefore, under Milestone 2030, the Group has set targets for absolute results, aiming to reduce CO2 steadily even as the businesses continue to grow.
The Bridgestone Group will contribute to the reduction of CO2 emissions during customers’ use, raw material/procurement, distribution and reuse/recycle phases of the product life cycle by providing customer value through Dan-Totsu (the clear and absolute leader) products/services. It also will reduce CO2 emissions from manufacturing. This allows the Group to reduce CO2 emissions across the product lifecycle and entire value chain.

CO2 reduction initiatives in the value chain
1. Raw materials and components procurement
While maintaining a firm focus on enhancing product safety, quality and performance, the Group intends to purchase materials with low carbon footprint and develop advanced materials that help reduce the resources used in the products.
The Group will improve manufacturing efficiency through equipment and process improvements to further reduce the energy invested in each product, while further developing products to help minimize impact on the environment and enhance product safety and quality. It will also actively pursue clean energy from renewable sources.
The Group will strive to increase transport efficiency by implementing better distribution strategies, including routing and delivery fleet performance, optimizing vehicle loading, selecting fleets/fuels with low CO2 emissions, and implementing solutions that leads to saving fuel and consequently CO2.
The Group will continue to focus on extending the life of its tires and expanding retreading (reuse) of truck, bus, aircraft and off-road tires, as well as reducing per-tire weight, to help reduce product waste generation. It will also continue to increase the amount of reduced, reused and recycled materials to achieve resource savings at all stages of the operations.
5. Product development
During the lifecycle of a tire, the Group estimates that 90% of tire-related CO2 emissions originate from a tire’s use on a vehicle. To help drivers and vehicles reduce emissions, it intends to develop more sophisticated tires with improved/reduced rolling resistance to lower fuel use, while also expanding educational programs on tire and vehicle maintenance and eco-driving.
The Group will also continue to develop other products to help save energy and reduce CO2 emissions, such as building materials with better properties.
The Group's focus on the environment and determination to achieve the CO2 emissions reduction targets will advance technologies across the lifecycle of its products, significantly reducing the environmental footprint while also helping customers reduce theirs. The Group's efforts are designed to help address climate change and build a more sustainable society.
Engaging with suppliers on climate change
To reduce CO2 emissions through tires’ lifecycle, the Bridgestone Group has engaged with its suppliers in various ways.
In 2018, Bridgestone Group introduced a new Global Sustainable Procurement Policy that includes minimum requirements and preferred practices to suppliers on Sustainable Procurement Practices incorporating environmentally responsible procurement including measures for climate change, reduction of GHG emission as well as the use of energy as one of four major areas. For next steps, the Bridgestone Group worked with EcoVadis to conduct enhanced environmental, social and governance (ESG) risk assessments to the suppliers for monitoring and evaluating their ESG status.
In early 2021, Bridgestone received the highest rating in CDP’s*1 Supplier Engagement Rating for the second consecutive year as a result of the company's reduction of CO2 emissions throughout all areas of its products' lifecycles-from raw material procurement to manufacturing, distribution, use, and disposal or recycling.
- The CDP, formerly the Carbon Disclosure Project, is a charitable organization that runs a global disclosure system for cities and companies to measure and manage their environmental impact.
Carbon neutral initiatives with wider stakeholders
The Bridgestone Group is promoting co-creation with stakeholders by encouraging open innovation in technology, business models and design, and combining technologies in various fields. For climate change action, the Group is also working with other organizations and businesses to accelerate carbon neutral initiatives. In Japan, Bridgestone is working as a member of the Japan Climate Initiative (JCI) and the Tokyo Zero-emission Innovation Bay council. In April 2021, Bridgestone endorsed a message by JCI calling for the government of Japan to set ambitious greenhouse gas emission reduction targets to realize the goal of Paris Agreement. The message, which calls for a 2030 reduction target of "going beyond 45% - aiming for a 50% emission reduction", was delivered as an open letter to Japan’s prime minister, foreign minister, minister of economy, trade and industry, and minister of the environment, and published by various media outlets.
Moreover, the Group is a major member of the Japan Rubber Manufacturers Association, which has been working to achieve 2020 and 2030 mid-term targets to reduce CO2 emissions during manufacturing as part of the Japanese Business Federation’s Commitment to a Low Carbon Society, which plays a central role for the industrial sector’s commitment.
Furthermore, the Group has pledged its support for the Challenge Zero initiative launched by the Japan Business Federation in collaboration with the Japanese government, which aims to realize a "decarbonized society" for Japan as a long-term goal in line with the international framework of the Paris Agreement.
Adaptations to address climate change
The Group is aware of the physical risks associated with climate change and has established BCPs and other risk management measures at our production sites. The Group also recognizes other potential issues related to climate change and is taking steps to help address them, such as by research and development on diversifying rubber materials and by studying how climate-related impacts might influence the supply chain.
Diversifying the world’s natural rubber supply
Natural rubber trees (Hevea brasiliensis) are the primary source of natural rubber today. Currently, more than 90% of the world’s natural rubber supply comes from rubber trees grown in tropical areas of Southeast Asia. The Group is actively researching ways to diversify the world supply of this vital raw material for the tire and rubber industry.
Specifically, the Group is researching methods for extracting and developing tire-grade natural rubber from guayule, a desert shrub native to the southwestern United States and northern Mexico.
For the details of Bridgestone’s research projects involving guayule, see “Action3: Expand and diversify renewable resources.”
Disclosures aligned to the TCFD recommendations
The Bridgestone Group supports the Task Force on Climate-related Financial Disclosure (TCFD) and its recommendations. Under a climate-related governance framework, the Group formulated a medium- to long-term strategy towards carbon neutral in light of the climate-related risks and opportunities. For strategy, the Group is working to reduce transition risks through climate change mitigation actions, such as reducing greenhouse gas emissions, while at the same time working to reduce physical risks through adaptive measures, such as diversifying natural rubber supply sources.
Going forward, the Group intends to expand its disclosure of climate-related actions in line with the TCFD recommendations.
