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

The Yokohama Rubber Group, which conducts production activities in 13 countries (Japan, United States, the Philippines, China, Thailand, Russia, Vietnam, India, Taiwan, Indonesia, Italy, Mexico and Israel) 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 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. To this end, we take steps to realize sustainable, appropriate energy use and reduction of energy consumption throughout the value chain, starting from the design and manufacturing stage, by developing and adopting environmentally friendly technologies and working closely with everyone involved in the provision of related products and services.
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 line with 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 total CO2 emissions in the base year (fiscal 2005).
  • Mid-term target:
    • At our domestic group companies, we will work towards reducing the ratio of greenhouse gas emissions by 25% compared to the base year (fiscal 1990) by fiscal 2020.
    • By 2030, reduce manufacturing-related CO2 emissions per unit of net sales, including both Scope 1 and Scope 2 emissions within the Group and (through collaboration with our partner companies) manufacturing-related CO2 emissions throughout the value chain, by at least 30% compared to the base year (2013).

Measures for vision achievement

We will implement the following measures aimed at promoting 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 will promote energy reduction activities.
  4. We will promote the development and sales of eco-products in order to reduce the amount of energy use when products are used.
Domestic GHG emissions were reduced by 15% compared to fiscal year 2005 as a result of system improvements (the development of energy-efficient vulcanization systems, and utilization of cogeneration), 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).

Reduction of energy usage and CO2

  • Target: Reduce CO2 emission by 25% by 2020 compared to the base year of 2006.
  • Results: While there was overland transport due to natural disasters, a 2.0% reduction in CO2 emissions to 19,592 tons was achieved over the previous fiscal year during fiscal year 2018 by reviewing transportation routes, reducing warehouse transportation volume and improving loading efficiency. On the other hand, emissions per unit improved by 1.5% at 40.7 KL per million ton-kilometers.

Energy management

  1. Use of in-house power generation
  2. Control of peak demand through demand control equipment
  3. Building and roof heat retention and insulation
  4. Production equipment investment (improving the efficiency of air conditioners, motors and pumps, and decreasing compressed air pressure)
Energy consumption per unit was reduced through the efforts noted above.

Full Operation of Co-generation Systems

At tire plants that use a large volume of energy and steam, it is possible to achieve a significant reduction in CO2 emissions through the adoption of co-generation systems that supply energy and steam at the same time. As of 2018, co-generation system had begun operation at three domestic plants. As a result of continuous 24-hour operations, 72% of the energy and nearly all of the steam used by these plants are now supplied by the co-generation systems, contributing to a reduction in CO2 emissions and a reduction in peak electric power consumption and in the overall amount of power purchased from the electric company. This was also adopted at the Thai Plant.

Improving the efficiency of production equipment motors and pumps

We have upgraded production equipment motors and pumps that consume large volumes of energy to high-efficiency models, and also reviewed capacity to achieve major energy savings compared to previous equipment.

Improving the efficiency of production equipment cooling-water pumps

We have upgraded the cooling-water pumps which play a vital role in supplying cooling-water for tire production facilities 24 hours a day with new, highly-efficient models, thereby reduced electric power consumption.

Adoption of LED lights

We have replaced the overhead lighting (mercury lamps and fluorescent lamps) for our buildings in Japan and overseas with LED lights and high-efficiency ones, resulting in significant power reduction for lighting.

Solar power generation

We are proceeding with the installation of environmentally friendly, renewable solar power generation facilities.
The facilities were adopted also in plants in India and China (Suzhou) in fiscal year 2017, and in the Philippines in fiscal year 2019.
Solar power generation (Suzhou, China) installed capacity: 3,000 kw
Solar power generation (Hangzhou, China) installed capacity: 80 kw
Solar power generation (India) installed capacity: 200 kw
Solar power generation (Mie) installed capacity: 500 kw
Solar power generation (Philippines) installed capacity: 4,000 kw

Energy Saving Month activities

Based on the vision of “Connect everyone’s wisdom and ingenuity, start winter energy saving on your own,” we shared awareness of the significance energy saving to “strengthen corporate competitiveness through cost reductions, respond to fossil fuel depletion, reduce the burden on the global environment, and have corporate social responsibility,” and made preparations for the practice; thereby during the energy-saving month of February, significant results were achieved through the accumulation of multiple small efforts, thanks to effective coordination between the production department, equipment maintenance department, and administration department at plants.
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 (switching equipment on and off), representing the adoption of a just-in-time system for energy.
Consultants provide guidance every year at business locations in Japan and overseas.
Provision of guidance by consultants
We will have reductions in total energy use as we plan to continue expanding the introduction of cogeneration systems.
With the aim of increasing the renewable energy usage ratio, we plan to expand the introduction of solar power generation, etc. in order to increase the percentage of our business locations that use renewable energy.
