Our policy

In 2021, we formulated our Global Environment Policy. We support international standards and adopt a precautionary approach in our efforts to help solve global climate change and other environmental challenges across the value chain. We take early action to address environmental issues through this precautionary approach such as risk assessments to support international norms, including the United Nations (UN) Rio Declaration on Environment and Development and Agenda 21 and 10 principles of the UN Global Compact, and fulfil our responsibilities.

Global Environmental Policy

  1. Fundamental Philosophy

The Toyo Tire Group aims to create a sustainable society, where we share all-encompassing affluence and joy with everyone involved in our business. To this end, we hereby pledge to fulfill our corporate responsibility to the global environment into the future, as we seek to achieve TOYO TIRE's SDGs for resolving social issues on a global scale.

  1. Action Guidelines

1）We comply with international rules and laws.

We will continue to support international rules for the protection of the global environment and work to comply with environment-related laws and regulations in the countries/regions where we operate.

2) We act to mitigate the impact of the climate crisis.

Climate change is causing various critical situations (climate crises) across the planet. We acknowledge that, for us to stay in business, it is of great importance to respond to this change and whatever changes the future may bring. While contributing to the achievement of internationally-committed goals, such as curbs on energy usage and reduction in CO₂ emissions, we will lay a foundation for our business continuity that minimizes the impact on our business in the wake of natural disasters.

3) We use water with the utmost care.

We are cognizant of the importance of ensuring access to safe water (fresh water) at our premises and their surrounding areas for business continuity. Accordingly, we will not only strive to reduce our water consumption but also minimize the impact that the intake and discharge of water that we utilize for our business activities may have on the areas surrounding our premises, with the aim of creating a social environment where it is perfectly safe to use water resources.

4) We do not waste resources.

We are also cognizant of how important it is, for the sake of business continuity, to use only the necessary amount of resources, conforming to a predetermined plan, on the premise that all resources on this planet are limited. We will also contribute to the development of an enriched social structure for utilizing resources with enhanced efficiency by using precious resources effectively and without waste.

5) We continue manufacturing with considerations given to the environment and people’s lives.

In each process of the value chain, we determine if precautions are taken to conserve the environment and ensure that chemical substances are used safely. We will adhere to these measures to continue to provide products, technologies, and services that enrich the environment and the lives of people.

6) We protect the rich natural environment and people's lifestyles in places where we source our raw materials.

Being fully aware of the fact that we consume large quantities of natural rubber as raw materials for our products, we will strive to protect bountiful forests in places of its origin, as well as the lifestyles of people living there in collaboration with all involved organizations.

7) We value communications with the public.

We are cognizant of the importance that, as a corporate citizen of society, we act with a full understanding of the enduring impact that our business activities may have. Therefore, we will strive to facilitate communications and build a better relationship with the public through a series of constructive and sound dialogues with them in order to ensure that we understand ourselves better and that the public develops an unobstructed understanding of our company.

Activities: Conserving water environments

Reducing water risk

The use of water is both indispensable for human life and welfare and a human right recognized by the UN. For that reason, the Toyo Tire Group considers water risks in corporate activities to be a key management issue.

Identifying water-related impacts on business activities (Manufacturing)

We are investigating the type of water security measures that companies should take with reference to the contents of the CDP water questionnaire. We at the Toyo Tire Group use the Aqueduct Water Risk Atlas released by the World Resources Institute’s Aqueduct program to identify water-related impacts on business activities around our manufacturing sites, and we strive to reduce our volume of water withdrawal and discharge by using water more efficiently in line with the magnitude of the impact. We confirmed that we have no operations in areas with a high risk of seasonal fluctuations in water supply, water shortages caused by drought, depletion of groundwater, or not being able to secure drinking water in surrounding locations.
We also confirmed* that, at this time, the Group does not take water from water resources that are considered high value from a biodiversity perspective, such as water areas that experts recognize as being particularly vulnerable or designated protected areas inside and outside Japan, or that are recognized as being of high value and importance to local communities and indigenous peoples. Furthermore, we have no business operations that discharge water into those water areas or water resources. For some influences where it is difficult for the Group to obtain sufficiently accurate information to formulate a report, we are prioritizing areas where water risks may increase going forward and working hard to grasp the current situation.

  • * Identification method: Use the following
    Ramsar Sites Information Service, UNESCO-World Heritage Center, Nature Conservation Areas (Japan’s Ministry of the Environment), natural monuments such as designated cultural properties (Japan’s Agency for Cultural Affairs)

Identifying water-related impacts on business activities (Manufacturing)

Identification method: Assessment by the Aqueduct Water Risk Atlas (World Resources Institute) as of the end of April 2023
Areas assessed: 12 regions where the Group has manufacturing bases
Evaluation results: At present, the areas around Zhucheng (China) and Chon Buri (Thailand) are regions under extremely high water stress. The areas around Perak (Malaysia) and Chon Buri (Thailand) are also currently at high risk of river flooding. The assessed forecast for 2030 is that, if stable economic development continues, water demand is likely to increase by 1.4 times the current level around Zhucheng (China) and Grad Beograd (Serbia), and 1.7 times the current level around Perak (Malaysia).

[ For current water-related impact assessment ]

Evaluation indicators: Baseline water stress, riverine flood risk

Scenario: Business-as-usual
Indicator: Water demand change from baseline

Long-term roadmap for nature targets

Countries, government agencies, and companies worldwide have come to realize the crucial importance of nature, initiating global initiatives that address natural capital. In 2023, the Taskforce on Nature-related Financial Disclosures (TNFD) published version 1.0 of its recommendations, while the Science Based Targets Network (SBTN) has launched the pilot implementation of its nature targets. At Toyo Tire Corporation, we developed a long-term roadmap in 2023 that recognizes nature and natural capital, which includes not only water resources but also sanitation and hygiene (WASH) and biodiversity. Going forward, we will work on actions at each phase in line with the roadmap.

長期ロードマップ

Reducing volume of water withdrawal and managing discharge appropriately

As a result of our efforts over a five-year period (2019–2023), we were able to achieve our goal of reducing water withdrawal at our Japanese manufacturing bases by 10% compared to 2018 levels in 2023.
Moving ahead, we will follow the long-term roadmap and continue working on our target to reduce water withdrawals at high-risk sites as well as minimize wastewater impacts.

Goal:

  •  • Reduce water withdrawal by 10% compared to 2023 levels by 2030 at our manufacturing bases located in areas of China, where had been assessed as extremely high risk for water depletion by Aqueduct.
  •  • Manage factors affecting water withdrawal variations and continue risk assessments.
  •  • Enhance data collection on water discharge volume and quality and continue risk assessments.

The Group mainly uses municipal or other public and private water supply facilities as well as groundwater for our boiler equipment and parts processing facilities, the cooling of production parts, cooling towers and welfare facilitates at our manufacturing bases. For water withdrawal and discharge, we are working on proper water-resource management throughout the Group using efforts such as improving equipment to reuse water as much as possible in each production process. In 2022, we reduced water withdrawal across all sites in Japan by 15.4% compared to 2018. Of our 23 main Group sites in Japan, 16 sites (70%) have established and are carrying out water management plans appropriately to reduce their environmental impact.

Activities: Contributing to the circular economy

Resource recycling

We believe it is the social responsibility of global manufacturers to make it their mission to help transition our society from one that consumes resources to one that recycles resources.
The Toyo Tire Group is using an increasing amount of raw materials as the scale of our production expands. We strive to secure a stable and sustainable supply of natural rubber, our prime raw material, and other materials at the procurement stage. At the same time, we are also working hard to promote research and development of new materials and improve product design and production processes to ensure more efficient material use. We are also evaluating materials that will help facilitate resource recycling.
We are also trying to extend the life of our products by manufacturing products with excellent durability during use and turning old tires into retread tires.

Resource recycling initiatives

  • Heat recovery from waste incineration
  • Switch from wooden to heavy duty resin pallets
  • Exploring alternatives to specified chemical substances
  • External initiatives for risk assessments of chemical substances, initiatives for addressing tire wear particles and used tires

High-quality Toyo Tires brand even for retread tires

The collection and recycling of used tires is an important issue for resource recycling in the tire industry. The Toyo Tire Group is striving to expand the use of retread tires as a way to address this issue.
A retread tire is a recycled used tire whose tread rubber (the rubber section that comes into contact with the road surface) has been replaced. With the exception of the tread rubber, the other parts of the tire are reused, which not only saves resources compared to new tires but also reduces CO₂ emissions at the production stage.* The energy-saving qualities can be further enhanced by using and managing them in conjunction with fuel-efficient tires. Thanks to these environmental performance features, retread tires are recognized as designated procurement items under Japan’s Green Purchasing Law.
The Group manufactures and supplies durable, high-quality tires, and users also rate our retread tires highly.
The usage history for the base tire of a retread tire is different for each tire. We supply tires that customers can use with peace of mind by building a detailed inspection system that spans the selection through to the pre-shipment of base tires and includes such checks as high-voltage inspections of damage conditions, inspections of the interior of the tires that cannot be detected from the outside, and durability checks of finished products.
We are helping promote resource recycling in the transportation industry by encouraging the spread of high-quality retread tires.

  •  * Assuming CO₂ emissions from the manufacturing of new tires of 100%, CO₂ emissions from retread tires are much lower at 41%. (Source: Japan Retreaders’ Association)

How We Produce Retread Tires

There are two ways of processing retread tires: (1) a remold method in which tread rubber with no pattern is attached to a base tire, which is then placed in a mold, vulcanized and imprinted with a pattern, and (2) a pre-cure method in which patterned tread rubber is attached to a base tire, which is then vulcanized in a vulcanizer. We use high-grade technology to produce tires using both methods.

Activities: Preventing chemical pollution

For necessary raw materials for continuous operations within the Group, we manage chemical substances in accordance with the laws and regulations of each market in which we operate and our business partner’s guidelines.
For instance, we have strictly managed the use, storage and disposal of specified chemical substances in Japan based on the Chemical Substances Control Law (CSCL). In accordance with the Pollutant Release and Transfer Register (PRTR) system, we assess the amount of targeted chemical substances emitted or moved and register with the relevant authorities. When transferring or providing other organizations with targeted chemical substances, we provide those organizations with a safety data sheet (SDS) in accordance with the SDS system stipulated by the CSCL. We also implement any necessary responses to European Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulations, the Global Automotive Declarable Substance List (GADSL), or revisions in business partner’s lists of managed chemical substances.
We are working to maintain a 50% or higher reduction in VOC emissions compared to 2000 levels and continue to reduce them in accordance with the Japan Rubber Manufacturers Association’s voluntary action plan on reducing VOC emissions. The plan covers 17 typical substances used in the rubber industry, with rubber solvents constituting over 60% of the Group’s emissions. We have currently reduced VOC emissions by roughly 80%, far exceeding our goal, but will formulate specific plans for improving manufacturing methods and processes in efforts to reduce emissions even further.
We manage fluorocarbons, which greatly impact ozone layer depletion and global warming, in accordance with Japan’s Fluorocarbon Emission Control Law, and control leakage at less than 1,000tCO₂.
