It has become exceedingly rare of late not to come across the word “environment” used in relation to
business. This is one indication that environmental issues are increasingly a management priority at
many companies. Hoya established pollution countermeasure committees at each of its factories in 1976,
and since that time has made ongoing efforts to protect the environment.
Hoya published its first environmental report, outlining the Company’s environmental efforts,
in 2000. The second edition of that report was published during the year under review. Environment
Report 2002 offers even greater disclosure of information, containing specific examples of environmental
preservation initiatives undertaken by each of the business divisions, site data from each division, and
specific figures on environmental accounting.
Reducing the Burden on the Environment
Hoya has focused on four areas in which continuous efforts are made to reduce the environmental burden
per unit of net sales.
1. Energy Consumption
Hoya has implemented a thorough energy conservation program encompassing all of its business divi-
sions. At the facilities level, buildings have been properly insulated, pumps and clean room air-condi-
tioning motors have been converted to energy-efficient inverter styles, and refrigeration units have been
upgraded to be more efficient. Energy conservation has also been extended to the human environment,
with temperature controls and more efficient lighting systems. As a result, the ratio of energy consump-
tion to net sales declined by approximately 16% from the previous fiscal year.
2. Water Usage
Increased water recycling and water conservation efforts helped lower the ratio of water usage to net
sales approximately 11% from the previous fiscal year.
3. Waste Volume
The recycling of concrete sludge, the thermal recycling of waste plastic, recycling of used florescent
bulbs and batteries, and the reuse of organic solvents resulted in a decline in the ratio of waste volume
to net sales of approximately 10% from the previous fiscal year.
4. Volume of Packaging Materials
A review of packaging methods and reuse of the cardboard boxes used to ship products led to a signifi-
cant decline in the ratio of packaging material volume to net sales of approximately 48% from the pre-
vious fiscal year.
Introduction of an Environmental Management System (ISO 14001 Certification)
Hoya announced its intention to adopt an environmental management system in line with ISO 14001
international standards in October 1996. By the end of fiscal 2000, nearly all mass production facilities
had obtained this certification. The Company has continued to work systematically toward certification
throughout the Group, and four more sites were certified during the fiscal year under review, bringing the
Company’s total number of certified sites to 33.
