Long-Term Vision (For 2050 and beyond) Contribute to Globally-Agreed Target (over 50% reduction of CO2 emissions)

Activity Concept

Greenhouse Gas Emissions by Tire Lifecycle Stage (Converted to CO2 Base)*1

As a company involved in the automotive industry, the Bridgestone Group is paying close attention to the impact of CO2 emissions. Based on the projections of IPCC*3 and other internationally recognized agencies, the Group has established a goal to reduce CO2 emissions in our business operations.

Our efforts to reduce CO2 emissions go beyond tire manufacturing. The tire lifecycle stage that accounts for the largest volume of CO2 emissions is “Use (Driving).” Tire contribution to automobile exhaust emissions can be lowered by reducing rolling resistance, thus improving vehicle fuel efficiency and contributing to the reduction of CO2 emissions from the vehicle. The Group will continue its efforts to reduce CO2 emissions throughout our products.

Along with striving to mitigate climate change by reducing the amount of CO2 emissions, the company recognizes the risk of climate change to Group activities and is implementing adaptation measures such as conducting research on sourcing natural rubber from areas other than tropical regions.

To reduce the volume of CO2 emissions over the entire lifecycle of a tire, the Bridgestone Group has set two CO2 reduction-related targets so that by 2020 the contribution from avoided emissions when the customer uses the tire exceeds the amount of its operations and products’ after-use.

  1. Greenhouse gas emissions throughout life cycle of 1 fuel-efficient passenger car tire (195/65R15): 243.9kgCO2e
  2. Greenhouse gas emissions from after-use stage: 13.1kgCO2e (emissions reductions: 12.5kgCO2e)

Mid-term Environmental Targets (by 2020)

Contribute to CO2 reduction at usage stage more than all other emissions in the product lifecycle by 2020
  • Reduce CO2 emissions per sales from operations and products’ after-use by 35%
  • Reduce rolling resistance of tires by 25% and thereby achieving CO2 reduction during use exceeds all other emissions in the product’s lifecycle

Difference in CO2 Emissions from Operations and Products’ After-use and Contribution to CO2 reduction at the Usage Stage

The Bridgestone Group is working to achieve its mid-term targets reduce the volume of CO2 emissions over the entire lifecycle of a tire. Considering the value when CO2 emissions from operations and products’ after-use are offset by contribution of CO2 reduction at usage stage*1, the reduction in 2016 was 67% (compared to 2005). We are continuing activities with a dual approach aimed at achieving that contribution to CO2 reduction during use exceeds CO2 emissions from our operations and products’ after-use by 2020.

CO2 Reduction initiatives involving business activity processes

1. Raw material and component procurement

While continuing its clear focus on enhancing product safety, quality and performance, Bridgestone will increase its focus on procuring more environment-friendly materials and developing advanced materials that help reduce resources used in its products.

2. Manufacturing

Bridgestone will improve manufacturing efficiency through equipment and process enhancements to further reduce the energy invested in each product, while further developing products to help minimize footprints on the environment, along with enhanced product safety and quality.

3. Logistics

Bridgestone will strive to increase transport efficiency through improved distribution strategy, including routing and delivery fleet performance.

4. After-use

Bridgestone will focus on prolonging the life of its tires and expanding retreading (reuse) of truck, bus, aircraft and offroad tires, as well as reducing per-tire weight, to help reduce waste generation rates. Bridgestone continues to pursue the 3R’s (Reduce, Reuse and Recycle) to enhance resource savings at all stages of its operations.

5. Product development

Regarding a tire’s lifecycle, Bridgestone estimates that about 90% of CO2 emissions related to a tire are generated by its use on a vehicle. To help drivers reduce emissions, the company will further enhance its development of tires with improved rolling efficiency to reduce fuel use, while also expanding educational programs on tire and vehicle maintenance and eco-driving.

Bridgestone will also continue developing other products to help save energy and reduce CO2 emissions, such as building products which insulate buildings and reflect energy in order to maintain temperatures.

Bridgestone’s environmental focus and these CO2 emissions reduction targets will advance technologies across the lifecycle of its products to significantly reduce their environmental footprints while also helping customers reduce theirs. These efforts are designed to help address climate change and build a more sustainable society.

Bridgestone’s initiatives for the climate change adaptation

In addition to efforts to reduce greenhouse gas emissions, the Bridgestone Group recognizes the potential issues surrounding climate change and has been taking steps to help address them, for example by addressing potential impacts to our supply chain.

Diversification of the world’s natural rubber supply:
Hevea brasiliensis, or natural rubber trees, are the major sources 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. The Bridgestone Group is actively conducting research to diversify the world’s supply of this vital raw material to the tire and rubber industry. Specifically, we are conducting research to extract and develop 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).
