Global warming preventive measures

KOKUYO is taking measures to significantly cut the amount of greenhouse gasses it emits in order to realize a low carbon society.


Summary for fiscal 2012

Unit Energy Consumption

The KOKUYO Group's CO2 emissions in fiscal 2012 totaled 25,760 tons, 708 tons more than in fiscal 2011. Emissions are calculated for the existing scope of operations and use the electricity emissions factor of 0.378 kg-CO2/kwh, which is the overall power average in 2000 reported by the Federation of Electric Power Companies. Based on estimates, there were emission reductions of 1,179 tons due to operational improvements and 326 tons due to equipment improvements. Manufacturing operations and closing and consolidating facilities raised emissions by 2,213 tons. As a result, there was an effective reduction in CO2 emissions of 1,505 tons from operational and equipment improvements. Consequently, excluding the effect of production activities, emissions were down 5.6% from the previous fiscal year, well above the target of 3.6%.

Looking at sources of CO2 emissions, there was a 604 ton decrease at factories because of higher manufacturing efficiency and other improvements. However, factories recorded a net increase in emissions of about 1,355 tons because growth in production volume raised emissions by 1,959 tons. For distribution activities, although emissions increased 380 tons because of the higher volume of operations, there was a net reduction of 126 tons due to heightened measures to conserve electricity and other energy use. At offices, emissions were down 521 tons because of the more efficient use of heating and cooling systems and the effective use of heat storage. Additionally, to use energy more efficiently, we oversee unit energy consumption, which is obtained by dividing energy consumption by sales. In fiscal 2012, our unit energy consumption was 3.3% less than in fiscal 2011.

Global warming preventive measures at factories

Operational improvements at factories lowered CO2 emissions by 559 tons. Examples of activities include replacing product molds faster, reviewing compressor operations, performing inspections, strictly following operating rules for production equipment, and conducting energy checks to reduce waste. Installing energy-conservation equipment like inverters and LED lighting cut emissions by 45 tons. Overall, factory CO2 emissions were 1,355 tons higher than in fiscal 2011, the result of increases of 1,188 tons in Japan and 167 tons at factories in other countries. However, higher production volume raised emissions by 1,959 tons, resulting in a net increase of 1,355 tons after deducting the 604 ton reduction from operational and equipment improvements.

Global warming preventive measures for distribution

Emissions associated with distribution (storage and shipments) were 126 tons less than in fiscal 2011. Constant measures to conserve energy resulted in operational improvements that cut emissions by 156 tons. Equipment improvements such as using energy-efficient lighting fixtures and reviewing the proper lighting of distributing centers lowered emissions by 221 tons. At the KOKUYO Logitem Ina Distribution Center, which has an automated multilevel warehouse, a power demand monitoring system was installed to hold down this facility's peak electricity use. Distribution CO2 emissions increased 383 tons in fiscal 2012 because of the larger volume of operations. Overall, though, there was a net reduction of 126 tons after including the declines of 377 tons from operational and equipment improvements and 132 tons from the closing and consolidation of distribution facilities.

Global warming preventive measures at offices

Offices lowered CO2 emissions by 521 from the previous fiscal year. To do this, a review of the methods of operating heating and cooling systems, a review of working styles, and activities like days for no overtime and going home early were implemented There were also measures to reduce electricity use, such as by replacing lighting fixtures with LEDs. At the Shinagawa office, an electric power visualization system is used to lower peak daytime power use through the efficient operation of heating and cooling systems and heat storage tanks. In addition, a program that encourages people to use public transportation for sales activities cut gasoline use by 22%, which is a 278 ton reduction in CO2 emissions. In fiscal 2012, the cool biz and warm biz campaigns were combined into a smart biz campaign that takes place all year.

Major increase in CO2 as emission figures deteriorate

emission factor

If the figures for each of the various countries on the greenhouse gas (GHG) protocol website made public by the World Business Council for Sustainable Development and the World Resource Institute are adopted as the figures for the CO2 emission coefficients and added to the Japanese CO2 emission coefficients based on the Law Concerning Promotion of Global Warming Countermeasures (figures by electric power utility in fiscal 2012 and actual coefficients in fiscal 2011), then the total rises 5,345 tons, to 31,105 tons.

All consolidated subsidiaries now included in emission calculations

Starting in fiscal 2012, the KOKUYO Group is including all consolidated subsidiaries in the calculation of CO2 emissions. As a result, emissions totaled 40,954 tons, including 1,839 tons at non-consolidated sales companies. Extending emission reporting to more companies and using a less favorable emission coefficient have resulted in significant changes for the KOKUYO Group. Consequently, we believe that the medium-term goals for emissions will have to be reexamined.

Solar power system at KOKUYO Product Shiga


KOKUYO has installed 1,020 solar panels on the roof of its Building C

KOKUYO Product Shiga has a strong commitment to protecting the environment, particularly with regard to nearby Lake Biwa. The company recently installed a solar power system and sells all of this renewable energy to the electric utility. Another benefit of this system is the ability to gain know-how about internal power generation and storage in order to establish a foundation for stable production activities in the future.
