Long-Term Vision (For 2050 and beyond) Contribute to globally-agreed target (over 50% reduction of CO2emissions)

As a responsible corporate citizen, the Bridgestone Group is paying close attention to science-based CO2 emission reduction goals and ongoing and projected impacts of climate change. Based on the projections of IPCC*1 and other internationally recognized agencies, the Group has established a goal to reduce CO2 emissions in its business operations. The Group’s long-term (2050 and beyond) vision is to contribute to the globally agreed target to reduce CO2 emissions. In the shorter term, the Group is focusing on reducing its CO2 emissions from direct operations and, more impactfully, indirect emissions from our products in-use, which offers the greatest overall CO2 reduction potential—reducing fuel combustion emissions when vehicles are moving.

Mid-term environmental targets (by 2020)

Contribute to CO2 reduction at usage stage more than all other emissions in the product lifecycle by 2020

Difference in CO2 emissions from operations and products’ after-use and contribution to CO2 reduction at the usage stage

To move toward our 2050 vision, the Bridgestone Group has established a primary 2020 mid-term milestone and target: reduced emissions footprint from customers’ use of Bridgestone tires will exceed the Group’s emissions from raw material procurement, product manufacturing, distribution and our products’ after-use.

Combining the CO2 reductions from operations and products' in-use, the Group is 95 percent closer to our 100 percent reduction goal, in comparison with the 2005 baseline*1

To achieve the 2020 primary mid-term milestone, the Bridgestone Group established two CO2 reduction-related sub targets:

•By 2020, reduce CO2 emissions per net sales from operations and products’ after-use*2 by 35 percent (from a 2005 baseline). In 2018, the Group achieved a 33 percent reduction.

•Also by 2020, reduce tire rolling resistance by 25 percent (from a 2005 baseline). In 2018, the Group achieved a 21 percent reduction.

The Bridgestone Group has a number of Group-wide and region-specific initiatives underway to reduce CO2 emissions. For example, to reduce CO2 emissions through tires’ lifecycle, the Bridgestone Group utilizes CDP to engage suppliers on climate change. In 2018, the Group engaged suppliers that account for 87.6 percent based on CO2 emissions of procured tire raw materials through the CDP Supply Chain Program.
Approximately 71 percent of requested suppliers responded (CDP Climate questionnaire response rate was 53 percent) and 28 percent of responded suppliers received at least a B- rating (Management level) from CDP. The Bridgestone Group also encourages suppliers to reduce their CO2 emissions and self-report their environmental data through CDP.

The Group is continuing activities with the dual approach aimed at achieving our goal of reducing CO2 emissions generated by the customer’s use of a tire enough to outweigh all other emissions produced during raw materials procurement, manufacturing and the afterlife of the product by 2020.

CO2 reduction initiatives in our value chain

1. Raw materials and components procurement

While maintaining a firm focus on enhancing product safety, quality and performance, we intend to purchase materials with low carbon footprint and develop advanced materials that help reduce the resources used in our products.

2. Manufacturing

We 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 the impact on the environment and enhance product safety and quality. We also actively pursue obtaining clean energy from renewable sources.

3. Logistics

We will strive to increase transport efficiency by implementing better distribution strategies, including routing and delivery fleet performance.

4. After-use

We will continue focusing on extending the life of our tires and expanding retreading (reuse) of truck, bus, aircraft and off-road tires, as well as reducing per-tire weight, to help reduce waste generation rates. We continue to increase the amount of reduce, reuse and recycle materials to achieve resource savings at all stages of our operations.

5. Product development

During the lifecycle of a tire, we estimate about 90% of tire-related CO2 emissions originate from a tire’s use on a vehicle. To help drivers and vehicles reduce emissions, we intend to develop more sophisticated tires with improved/reduced rolling resistance for lower fuel use, while also expanding educational programs on tire and vehicle maintenance and eco-driving.

We will also continue developing other products to help save energy and reduce CO2 emissions, such as building materials with better properties.

Our focus on the environment and determination to achieve our CO2 emissions reduction targets will advance technologies across the lifecycle of our products, significantly reducing our environmental impact while also helping customers reduce theirs. Our efforts are designed to help address climate change and build a more sustainable society.

Additionally, all research and development operations at the Technical Center in Rome (Italy), including the Proving Ground where tires are tested, are certified according to the ISO 50001 Standard (Energy Management System).

Mitigating climate change

Bridgestone is a major member of the Japan Rubber Manufacturers Association and engages with the government on CO2 reduction through the Keidanren’s Commitment to a Low Carbon Society.

Adaptations to address climate change

While we seek to reduce our greenhouse gas emissions, we also recognize other potential issues relating to climate change and are taking steps to help address them. For example, the research and development on diversifying rubber materials, and studying how any climate related impacts might influence our 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 percent of the world’s natural rubber supply comes from rubber trees grown in tropical areas of Southeast Asia. We are actively researching ways to diversify world supply of this vital raw material for the tire and rubber industry. Specifically, we are researching methods for extracting and developing tire-grade natural rubber from guayule, a desert shrub native to the southwestern United States and northern Mexico, and Russian dandelion (Taraxacum kok-saghyz), a perennial temperate plant indigenous to Kazakhstan and Uzbekistan.
