Stance and target

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

The Yokohama Rubber Group that conducts production activities in ten countries around the world uses a large volume of energy in each business process. Because the reduction of energy consumption will lead to a response to the issue of climate change that is a problem on a global scale, the effective use of resources that are becoming depleted, and cost reductions, we have selected energy as a critical issue to be addressed.

Policies and stance relating to energy

The Yokohama Rubber Group has embodied our stance towards the environment in the Environmental GD100 and Yokohama Rubber Environmental Policy and will work to minimize the burden on the environment by the provision of products and services in accordance with the Yokohama Rubber Group Action Guidelines.
We will conduct activities in an aim for the appropriate use and reduction of energy in accordance with international agreements concerning the proper use of energy, the regulations of countries where we conduct business (such as Japan’s Act on the Rational Use of Energy and Act on Promotion of Global Warming Countermeasures), and the policies of related organizations.

Vision (attainment goal) / target

In aim of our shared global goal of reducing greenhouse gases by half by 2050, the Group is working to reduce total greenhouse gas (GHG) emissions as an energy use reduction target.

  • Long-term target:
    By 2050 reduce total CO2 emissions throughout the entire value chain of the Group by at least 50% of that in the base year (2005).
  • Mid-term target:
    • By 2030 reduce total CO2 emissions per unit of net salesthroughout the entire value chain of the Group by at least 40% of that in the base year (2005).
    • At our domestic group companies, we are working towards reducing the ratio of greenhouse gas emissions by 25% compared to base year (1990) by FY 2020.

Measures for vision achievement

We will implement the following measures in an aim for the appropriate use and reduction of energy throughout overall business activities.

  1. Promotion of a modal shift in logistics
  2. Management of energy in production
    We will promote the effective use of energy through system improvements, savings improvements, process improvements, the development of management systems, the introduction of production systems, and the introduction of new energy (renewable energy) in the production process.
  3. The Yokohama Group will establish seven energy-saving subcommittees under the supervision of the Global Warming Countermeasures Committee and promote energy reduction activities at suppliers.
  4. We will promote the development and sales of eco-products in order to reduce the amount of energy use when products are used.

Review of FY 2014 activities

GHG emissions were reduced by 15% compare to FY 2005 as a result of system improvements (the development of energy-efficient vulcanization systems, utilization of cogeneration systems), savings improvements (expanded use of LED, improvements in capacity utilization), process improvements (optimization of the rubber kneading process), and the introduction of new energy (introduction of solar cell power generation systems).

Case introduction

Reduction of energy usage and CO2

  • Target: Reduce CO2 emission by 25% by 2020 compared to the base year of 2006.
  • Results: A 0.8% improvement in emissions per unit was achieved over the previous fiscal year during FY 2014 through modal shift expansions that resulted in CO2 emissions of 23,297 tons.

Energy management

  1. Use of in-house power generation
  2. Control of peak demand through demand control equipment
  3. Building heat retentions and insulation
  4. Production equipment investment (improve efficiency of motor and pump)

Emissions per unit were reduced through the efforts above.

Full Operation of Co-generation Systems

At tire plants that use a large volume of energy and steam, it is possible to make a significant reduction in CO2 emissions through the adoption of co-generation systems that supply energy and steam at the same time. As of FY 2014, co-generation systems has worked at three domestic plants. As a result of continuous 24-hour operations, 60% of the energy and nearly all of the steam used by plants has been supplied, enabling us to achieve a CO2 reduction.

Improve efficiency of production equipment motors and pumps (reduction of fixed power for 24-hour operations)

We will update production equipment motors and pumps that consume large volumes of energy to high-efficiency models and also review capacity to achieve major energy savings compared to previous equipment.

Adoption of LED lights

We will renew the overhead lighting (mercury lamps and fluorescent lamps) for our buildings in Japan and overseas with LED lights and high-efficiency lighting. We are achieving significant results in power reduction for lighting.

Energy Saving Month activities

Based on the slogan of "building up team efforts aimed at a goal by aggressively taking on energy saving challenges," during the energy-saving month of February, energy costs were reduced by 2% YoY thanks to the accumulation of small efforts were achieved thanks to the integrated efforts that were made by the production department, equipment maintenance department, and administration department at plants.

Education activities during the energy - saving month

Education activities during the energy - saving month

Activities to strengthen energy management based on guidance from consultants.

We are strengthening energy guidance through means such as reductions in energy loss in line with production variation consisting of facility operation and stops (adoption of a just-in-time system for energy).
Consultants provide guidance every year at business locations in Japan and overseas.

Issues and future improvement measures

We expect to achieve targets for reductions in total energy use as we will continue to expand the introduction of cogeneration systems.
In an aim to increase the use ratio of renewable energy, we plan to adopt solar power generation, etc. at locations such as Europe and North America in order to increase the percentage of our business locations that use renewable energy.
