PREVENTION OF AIR POLLUTION

Prevention of Air Pollution
Casio promotes the reduction of SOx, NOx and dust emissions
through facilities and energy conversions.
Global Environment and Casio
The emissions of SOx, NOx and dust are
shown in the following graph.
In the Electronics Equipment Division,
the emissions of SOx and NOx have increased
substantially since fiscal 2003.
This is due to the full-capacity operation of
co-generation, which burns heavy oil, at
Yamagata Casio Co., Ltd. as growing production
necessitated an increase in electricity.
The measured values of emissions at
Yamagata Casio Co., Ltd. clear the ordinance
standards.
Co-generation was introduced to lower
CO2 emissions per unit of production. The
CO2 emissions per unit of production were
0.038 ton-CO2/¥1 million lower in fiscal
2004 than in fiscal 2001, which precedes
the introduction of co-generation.
􀋙 Efforts to Reduce Emissions
Regarding SOx, NOx and dust emissions,
Casio will promote the use of turbo freezers,
the gentlest kind of freezers to the environment,
as a company-wide policy. In
addition, Casio will promote the replacement
of heavy oil with such fuels as kerosene

and city gas to reduce emissions.
In fiscal 2004, fuel for absorption-type
freezers was changed from heavy oil to
kerosene in an effort to reduce SOx, NOx
and dust emissions.
Furthermore, old boilers at Casio Hitachi
Mobile Communications Co., Ltd. and Hachioji
Research and Development Center
were replaced with new models that emit
little SOx, NOx or dust in the building that
went through remodeling and additions,
drastically reducing their emissions.
􀋙 Emissions of SOx, NOx and
Dust at Overseas Sites
In fiscal 2004, Casio Korea Co., Ltd. and
Casio Electronics (Zhongshan) Co., Ltd.
were able to reduce their NOx and dust
emissions, thanks to facilities alterations.
However, SOx emissions at Casio Electronics
(Zhuhai) Co., Ltd. increased as adequate
measures were not implemented.
The company plans to take action toward
reduction of emissions in the future.
As of fiscal 2004, there are no facilities
that emit NOx, SOx or dust at Casio’s overseas
sites with the exception of Casio Korea
Co., Ltd., Jiu Shui Keng Casio Electronics
Factory, Casio Electronics (Zhuhai) Co.,
Ltd. and Casio Electronics (Zhongshan)
Co., Ltd.
