Stance and target

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

Yokohama Rubber Group’s use of water consists of two forms: the use of water such as cooling water for boilers and production facilities at production bases (direct use) and the use of water at suppliers such as raw equipment (indirect use).
For direct use, the risks (physical, regulatory, reputation risk, etc.) vary depending on the region of each business location. For this reason, we believe that it is important to effectively use precious water resources in line with the characteristics of each production base.
In addition, for the indirect use of water in the production process for raw materials such as natural rubber as well, we believe that it is necessary to confirm the situation and take the appropriate responses as necessary. This is based on our stance that if it is not possible to procure raw materials due to water-related risks at suppliers, it could directly result in serious problems that affect our operations.

Water use policy

Our domestic bases have rich water resources and while we use these resources effectively as a recycled resource*, there are areas with water use constraints among overseas business locations. For this reason, it is necessary to conduct water risk assessments in these areas and work to ensure that water is properly managed. We also believe that it is necessary to confirm that state of water use at suppliers and work together to adopt countermeasures in the event of water risks arising.
For this reason, we will conduct the following measures in the three years from 2015. Furthermore, we will broadly release the progress of these measures through means such as external questionnaires (CDP’s water, etc.).

* We use water based on formal procedures such as agreements with regions (governments).

FY 2015 FY 2016 FY 2017
Visualization of information
  • Understanding the situation in Japan and overseas
  • Formulation of water management standards
Establishment of mid-term target (FY 2020)
  • Deployment of water management standards
  • Establishment of an activity flow system
  • Consideration of supply chain initiatives
Commencement of implementation of mid-term target
  • Implementation of water management standards (strengthening risk management)
  • Creation of long-term roadmap (FY 2030 and 2050)

Water risk assessments

For many production base areas that use a lot of water, we use existing water risk assessment tools such as WRI’s Aqueduct to confirm potential water risks. As there are cases of gaps with realistic water risks with only existing tools, we also incorporate local information to make judgments on comprehensive water risks.
Based on these results, we identify the highest risks among representative water risks for each business location (physical, regulatory, reputation risk, etc.), and consider measures from the highest priority risks.

Vision (attainment goal) / target

  • Strengthen measures to reduce the amount of water used in locations with high physical (water shortage) risks
  • Ensure thorough wastewater quality management in locations with high regulatory risks
  • Strengthen local communication in locations with high regulatory risks

Through measures such as the ones described above, we will strengthen initiatives for these water risks and promote optimal water use.

Measures for vision achievement

At domestic and overseas production bases, we conduct initiatives aimed at reducing water intake per unit of output by 1% year-on-year.
During FY 2015 we will proceed with the visualization of information and during FY 2016 we will establish a mid-term target.

Review of FY 2014 activities

  • We have conducted water risk assessments at production bases that started operations prior to FY 2013.
  • We collected a questionnaire on CDP supply chain water in 2014 and reported to suppliers.
  • We have implemented the effective use of water at all business locations through continuous leakage prevention and improvements to equipment using recycled water.
    In particular, water closed systems have been introduced at many overseas production bases in response to physical (water shortage) risks.

Case introduction

We have made capital investments at domestic production bases in leakage protection for facility pipes and recycled water use facilities at business locations in Mie and Onomichi.
At overseas production bases, a closed system was introduced at the time of plant construction in India.
In addition, biodiversity conservation activities are conducted at Mie, Shinshiro, Mishima, and Ibaraki to investigate the impact on rivers that are water discharge sites.

Issues and future improvement measures

A framework will be established for the assessment of global data on water use, and the following initiatives will be implemented.

  • Yokohama Rubber Group standards (guidelines) for the proper management of water
  • Improve internal awareness of the water initiatives and the need for these initiatives
  • Jointly implement water initiatives throughout the supply chain
