Stance and target

Why is "Supplier Environmental Assessment" a critical issue to be addressed?
Explanation of the reason and background

The raw materials used in the major products of the Yokohama Rubber Group contain many petrochemical products (chemicals) including various types of synthetic rubber that can cause environmental pollution and have a negative impact on the lives of local residents during the manufacturing process. Because the worst case can lead to suspension of operations at suppliers, we have selected environmental impact assessments of suppliers as a critical issue to be addressed from both the perspective of the stable procurement of raw materials and the perspective of ethics.

Environmental impact assessment at the start of new business relationships

When adopting new raw materials, it is confirmed whether the materials comply with various regulations, and suppliers are asked to submit documents to serve as evidence of compliance.

  1. Quality control survey form
  2. Raw materials standards
  3. Shipped materials inspection report
  4. Safety data sheet (SDS*) (the applicable raw materials are chemicals that include rubber compounding agents that SDS is applied to)
  5. Specific toxic chemical substances survey form
  6. Pledge of non-inclusion of substances prohibited by the European ELV Directive*
  7. Data proving non-inclusion of substances prohibited by the European ELV Directive
  8. Four heavy metal substances survey form

In addition, we have issued the Green Procurement Guidelines that indicates the Green Procurement Policy of the Yokohama Rubber Group and our requests to suppliers in order to gain an understanding of these matters.

* SDS: Safety data sheets are international standard-forms to provide information on the characteristics and handling of chemicals when transferring or providing chemical substances or products (chemicals) that contain them.

* EU ELV Directive: An EU directive aimed at reducing the impact of end of life vehicles (ELV) on the environment.

Assessment of environmental impact in the supply chain

We ask suppliers to conduct a CSR self-check that includes a self-evaluation to report on matters including environmental management systems, substances of concern, and greenhouse gases.

Countermeasures in response to suppliers found to have a significant impact on the environment

While there have not been any such cases up until now, in such a case we will hold direct discussions with supplier plants on improvement points, causes, and improvement measures, and then implement these measures. We will suspend transactions in cases when improvements are not seen or malicious cases such as false reports.

Vision (attainment goal) / target

Have self-checks completed by all primary suppliers and conduct visiting audits to major suppliers by FY 2017. We believe that checks from third-party perspective may also be necessary in some cases in the future.

Measures for vision achievement

Study meeting have nearly been completed for procurement representatives at domestic and overseas business locations of the Yokohama Rubber Group. For the procurement representatives of overseas business locations we also conduct education and ensure awareness of the purchasing code of conduct through global procurement meetings, and we develop audit personnel for the self-checks requested of suppliers.
In addition, by holding study meetings for domestic suppliers, we communicate the policies of the Yokohama Rubber Group towards requests to suppliers including those related to the environment and make an appeal for understanding of self-checks and visiting audits. We will work to further expand the scope of such meetings going forward.

Review of FY 2014 activities

  • Among all 74 new suppliers in Japan, there were no suppliers that caused an environmental impact.
  • A CSR study meeting was held that was participated in of 299 of 342 suppliers.
  • All members of procurement departments received compliance training.

Green procurement

Yokohama Rubber has been working on the development and usage of raw materials to contribute to the environment under the cooperation of our business partners with preservation of forest resources, control global warming, usage of recycled raw materials, and expansion of non-petroleum raw materials as the main themes.
Furthermore, we manage parts procurement based on the Yokohama Green Procurement Guidelines. We ask that all suppliers confirm whether products contain SOCs (substances of concern) and ask that they submit a statement of non-use.

Reductions in CO2 emissions from shipment (promotion of local procurement adoption)

Significant advances were made in the adoption of local procurement in at plants in China. In addition, we were able to switch from raw materials important from Japan to local procured goods at plants in North America as well.
In addition, we are also advancing with the adoption of Russian raw materials at plants in Russia (26% in FY 2013, 48% in FY 2014).

Yokohama Green Procurement Guidelines

With the management of chemical substances contained in products as a form of entrance control, we ask that suppliers work towards environmental preservation and manage procurement items in accordance with our Green Procurement Guidelines.
Furthermore, based on our Green Procurement Policy, we purchase raw materials, outsourced items, subsidiary materials, and equipment in accordance with environmental footprint standards.
A revised English version will be prepared for distribution to business locations overseas.

Green Procurement Policy

We procure raw materials, parts, packaging, etc. that are environmentally friendly, clean, and safe.

  1. We make decisions on procurement and purchasing based on the status of environmental management system adoption by each supplier.
  2. We work to thoroughly prevent the inclusion of substances of concern (SOCs).
  3. We promote the purchase of environmentally-friendly products (green procurement).
  4. We reduce waste.

Specifically, we confirm (1) the status of environmental management system acquisition, (2) the status of environmental preservation initiatives, and (3) the status of substances of concern (SOC) management systems. As a requirement for products to be procured, we request the submission of documents such as (1) a substances of concern (SOC) survey form and (2) a pledge of non-inclusion. An image of substances of concern (SOC) survey form is displayed for reference.

Issues and future improvement measures

Because the number of suppliers is also on the rise as our business expands, creating a database of supplier information including environmental impact is an urgent task.
In addition, we recognize keeping self-checks by suppliers uniform at a high level as an important issue, and accordingly we will increase the number of study meetings and implementation locations accordingly. In order to promptly implement the above, we recognize the need to aim for further improvements in the level of procurement representatives at the domestic and overseas business locations of the Yokohama Rubber Group.
