Energy use is related to the emission of carbon dioxide (CO2). Such emissions are reported to affect the environment in the form of global warming and other problems.
CO2 Emissions and Reduction Measures
Under the Daifuku Environmental Vision 2020, the Daifuku Group strives to reduce CO2 emissions from its business activities to help prevent global warming. Although total CO2 emissions from business activities increased as sales rose in fiscal 2012, we reduced total emission 34.6% and emissions per unit of net sales 21.8% compared with the fiscal 2005 level, exceeding the respective Group targets of 17% and 10%. These reduction measures were the result of power saving measures, including enhanced Companywide efforts to save energy in summer and winter, the adoption of an electric power monitoring system at the Shiga Works, and changes to ventilation heating sources for cleanrooms.

Environmental Impact of Transportation
Total transportation-related emissions of CO2 per unit of net sales in fiscal 2012 were reduced 18.5% compared with those of fiscal 2005, exceeding the Group target of 12%. We strove to reduce environmental impact through efficient transportation mainly by improving packing and transportation methods, moving from individual shipping to the milk run method, and promoting modal shifts.

Sharing transportation resources

Typically, trucks are used to transport products to customer sites. Given the environmental impact of these vehicles, Daifuku decided to shift to more environmentally friendly railway and marine transportation. In fiscal 2012, Daifuku cut CO2 emissions by 368 tons by carefully selecting modes of transportation.
- *Milk run method: One truck makes the rounds to each supplier and picks up cargo that had previously been delivered by separate trucks. This method improves load efficiency and reduces fuel consumption and CO2 emissions.
- **Modal shift: Choosing modes of transportation with lower environmental impact, such as railroads and ships, to transport cargo. By switching from trucks to ships and trains, it is possible to transport cargo with fewer CO2 emissions and less impact on the environment. Transportation efficiency is also improved because larger volumes are moved at one time.
Energy Conservation Efforts
Our CO2 reduction efforts range from large-scale operational improvements to individual employees reducing their commute and travel when on company business. Daily data on the use of electricity and heat energy, the major contributors of CO2 emissions, are constantly monitored for improvement.

Using solar power to preserve the environment
The lights along Shiga Works' Yasuragi Road* are powered by solar energy. The road is lit at night by solar energy accumulated and stored during the day.
An employee-friendly walkway was built alongside the retention pond at Shiga Works. To make the walkway inviting to employees, we lined the 720m road with cherry trees, flowering plants and maple trees, to best capture the beauty of each season. Yasuragi is a Japanese word meaning comfort and relaxation.
