We are a transportation manufacturer focusing on automobiles. Automobiles, a convenient and comfortable form of transportation, are now indispensable for living in a modern society. On the other hand, automobiles draw on limited global resources as materials and fuels. Consequently, they emit CO2, which causes global warming, as well as other air pollutants. We have to work very hard to realize an affluent automobile society but fully understand that automobiles also have disadvantages as well as their benefits. With these in mind, we must work even harder for a better future. SUBARU accepts the task of working towards the fusion of a global environmental response (drastically improving fuel economy and reducing gas emissions) with the benefits of automobiles (pleasant driving, comfort, and reliability) by considering environmental impacts and reducing the environmental burden throughout the entire life cycle of automobiles, including development, production, use, disposal, and recycling.
We have installed a total of six natural gas cogeneration systems in Utsunomiya Manufacturing Division, Gunma Manufacturing Division, and SUBARU General Training Center. These systems not only generate power but also utilize exhaust heat for air conditioning and other purposes. In July 2012 we installed an additional cogeneration system as a countermeasure against power supply shortages.
As well as these cogeneration systems, we have been implementing various means of CO2 emissions reduction and energy saving, such as reducing standby electricity and making energy intensive processes more efficient. Although the total emissions volume varies from year to year due to changes in production volume, a total of about 203,000 tons of CO2 was emitted in FY2012. This was 26% lower than the level of FY1991. We successfully achieved our FY2012 target set in the 4th Voluntary Plan for the Environment, which was a "15% reduction for the total CO2 emissions volume against FY1991," and then realized our subsequent target to "further reduce CO2 emissions by 22% against the FY1991 level."
Power shortages have become increasingly serious following he Great East Japan Earthquake. During summer 2011, when supply insufficiencies were common, we participated in reducing the nation-wide peak power usage as a member of the automobile industry by altering our business closing days from weekends to Thursdays and Fridays. We also managed to keep power consumption at our business sites, where power is supplied by Tokyo Electric Power Co., Inc., down to 85% of the allowance by increasing the efficiency of our business operations and introducing our own power generation systems.
Super Cool Biz as an Energy Saving Measure
In the Shinjuku SUBARU Building, Omiya SUBARU Building, and SUBARU General Training Center, we adopted the "Super Cool Biz scheme" from June 1 to October 31 as a part of our FY2012 summer energy saving measures. The Super Cool Biz scheme allows employees to wear light and less formal clothing in the office during the summer time so that they can work comfortably with the room temperature set to 28℃+1℃. This group effort by many employees resulted in reducing power consumption by 15% during the period.
