Message from the President
Thank you for reviewing the Environmental Report ofDenyo Co., Ltd. I would also like to thank you for yourinterest in our company.
Our lives as human beings are much richer than in thepast. On the other hand, we have been using resources
rapidly, and resources to leave for future generations
have been further decreasing. In addition, in recent
years environmental problems all over the world havegrown more serious such as disasters frequently caused
by abnormal weather.
Under such circumstances, Denyo Co., Ltd. will think
daily about what we can do as a company in“Developing Technology Tomorrow's Power Needs” andtackle environmental problems seriously with an aim todeliver a sustainable society.

As well as contributing to social infrastructure upgrades worldwide
through our power source products, Denyo is profoundly aware of its
corporate social responsibility to conserve the environment, and tirelessly
promotes environmentally sound business activities.

Eco-Friendly Products
Developing Products with High Environmental Performance
Eco-Base Generator
The Eco-Base Generator is designed to reduce the risk of environmental pollution
which might occur in the event of an engine oil leakage caused by unforeseen
circumstances. By utilizing the eco-base installed at the bottom of the main unit, leaks
are contained.
In addition, the generator comes in a structure that is carefully designed to prevent
rain infiltration. This ensures that almost no rainwater gets into the generator when it
is not in operation. Even if rainwater enters the unit and the eco-base becomes full,
the water is discharged from the equipment ahead of the oil as the oil and water
separation system is standard equipment for the generator.
The unit also comes with a new swivel oil drain, which ensures higher workability
than the previous drawer drain.

Variable-pressure, variable-capacity motor compressor

The engine-driven welder is also equipped with an eco-base, which enables theunit to reduce the risk of environmental pollution from an oil leakage in the event ofan unforeseen circumstances by containing the oil at the bottom of the main unit.
The same as the eco-base generator, the welder comes standard with the oil-water
separation system. Therefore, even if rainwater enters the welder and the ecobase becomes full, the water is discharged from the equipment ahead of the oil.
It also features a double structure, in which fuel spilled during fueling is caught by aseparate tub before being pooled in the eco-base. This enables the welder to be
used with confidence at construction sites of industrial complexes and power
stations and in work sites where environmental protection is required.

DLW-300LSE*An illustration showing theeco-base at the bottom ofthe unit

This compressor comes with a variable pressure system, which permits theuser to set it any level of discharge pressure and select from three different
levels of the maximum discharge pressure. It can therefore be operated in an
optimal condition for usage load and input power capacity.
Use of an inverter has significantly reduced the striking current compared tothe previous star-delta starting. Power consumption and noise are also much
lower because the unit controls the volume of air from the electric fan inaccordance with the internal temperature.
In addition, the combination of purge unload (standby control at reducedpressure) and auto start/stop function enables even more energy-saving
operation.

Global Warming Prevention
Reduce CO2 Emissions
Denyo endeavors to prevent global warming through initiatives to reduce CO2 emissions due to business activities.
CO2 emissions in FY2014 were 5,321 tons, an increase of 9.7% from the FY2012 levels. This is because of the increase of conversion factor for CO2emission coefficients for power consumption, which are determined by electric power companies. Our power consumption before conversion to CO2 emissions
coefficients decreased 11.6% from the FY2012 levels. The amount of the consumption of fuels also decreased 10.9% from the FY2012 levels.
We will continue to implement initiatives to cut CO2 emissions during FY2015.

Reduce Solid Waste
We manage and process solid waste appropriately and in compliancewith all laws and ordinances.
In FY2014, we discharged about 213 tons of industrial waste, down by
52.3% per output compared to the FY2012 levels, which is far above
the target.
We are also working toward a new target of cutting the volume ofindustrial waste per output by at least 20% compared to FY2012 levelsby the end of FY2017.

Managing Chemicals
Managing Chemicals Subject to PRTR
Based on the PRTR Law, we compile and release data on chemicals
subject to the PRTR including amounts released into the environmentor transferred as solid waste.
*A Pollutant Release and Transfer Register (PRTR) is a system for compiling and disclosing dataon hazardous chemical substances including their sources, how much is released into theenvironment or transferred off-site with solid waste.

Environmental Measures for Buildings
Green Roof at the Head Office
Based on the philosophy of promoting environmentally sound businessactivities, Denyo started installing a green roof at the head office in FY2013.
The rooftop garden provides some control over temperature increases in thebuilding. It also alleviates the heat island phenomenon and improves airconditioning efficiency.
When planter boxes are included, the green roof at the head office occupies
38% (40.88m2) of the roof area. The soil is a light-weight artificial soil that canwithstand the dry summer period. With approximately 20 thriving species
focused on flowers reminiscent of the four seasons, the garden also contributes
to wellbeing.

coating. This filters out 99% of ultraviolet rays and 90% of infraredrays. By reducing ultraviolet rays, the coating protects the eyes of thepeople working in the building. By cutting infrared rays, the coating not
only improves the air-conditioning efficiency in summer but also
retains heat in winter, thereby saving power consumption. By using

Environmental Measures at Production Sites
In August this year, Plant Warehouse Building No. 8 wascompleted at the Fukui Plant. This building uses LED ceilinglights to save energy. In addition, all of the doors are madeof semitransparent resin, which lets in natural light.
The equipment of existing plant buildings is also being
replaced with eco-friendly alternatives, one by one. The useof LED lights is also being expanded.

OthersStudy Tours of Fukui Plant
At Fukui Plant, we organize a wide variety of events to promote anunderstanding of Denyo among local residents and make the company
more familiar to them. Those events include plant study tours for local
elementary school children and high school students and an internshipprogram for high school students.
We will continue to proactively organize such events with a strong
awareness of the fact that the understanding of local residents isessential for continuing our operations, and with an aim to further
strengthen our relationship with local people.

Blood Donation at Fukui Plant
At Fukui Plant, we make a blood donation two times a year. A large
number of employees donate blood each time, and the amount wedonate at a time is as much as the daily amount needed for the entire
Fukui Prefecture. At Denyo, we thus commit ourselves to activities forcontributing to the local community.
