The HOYA Group actively engages in environmental preservation efforts as part of its corporate social responsibility in order to pass on to future generations a global environment in better shape than today.
Structuring of a Global Management System for its Environmental and Occupational Safety and Health Management System
The HOYA Group has been structuring a globally-operated management system based on ISO (International Organization for Standardization) 14001 and OHSAS (Occupational Health and Safety Assessment Series) 18001 with the purpose of promoting the environmental protection activities by the employees and ensuring the safety and health of the employees.
In February 2013, the Group was granted a global multisite certification.
HOYA Strategy for CO2 Reduction
The HOYA Group is globally operating its environmental protection activities, in which attempts are being made to reduce CO2 emissions by paying special attention to its “energy usage.”
CO2 Reduction Targets:
The HOYA Group also sets the following Group-wide reduction target for CO2 emissions and is directing its environmental protection activities toward accomplishing it. That is, the HOYA Group aims to achieve a 7-percent reduction of CO2 emissions from the fiscal 2008 level by fiscal 2015.
From fiscal 2016, the HOYA Group sets the new reduction target for CO2 emissions and is directing its environmental protection activities toward accomplishing it. That is, the HOYA Group aims to achieve a 5-percent reduction of CO2 emissions from the fiscal 2014 level by fiscal 2020.
The CO2 emissions of the HOYA Group in fiscal 2015 were 332,036 tons of CO2．
The reduction of CO2 emissions was 6.7 percent in Japan, 5.2 percent overseas and 5.5 percent globally from the fiscal 2008 level.
In FY2015, CO2 emissions increased in Japan and overseas due to increased production globally.
As a result, it wasn't possible to achieve 7 percent reduction.

|Fiscal 2008||Fiscal 2009||Fiscal 2010||Fiscal 2011||Fiscal 2012||Fiscal 2013||Fiscal 2014||Fiscal 2015||% Change from Fiscal 2008|
Note that the CO2 emissions are calculated, for each of the production bases (*1), from the electric power and fuel consumptions as determined by the summation formulas standardized for the whole HOYA Group.
*1 Some of non-production bases are included.
Case Examples of Activities for Reducing Environmental Burdens
The HOYA Group has been practicing various environmental burden reduction activities under its Environmental Philosophy and Fundamental Environmental Policies.
1. Soil pollution control measures, underground water pollution
control measures, hazardous substance leak control measures
In March 2010, the Group issued the HOYA Group Standard for Environmental Facilities, which was designed to promote the duplexing of piping and underground tanks and the exact performance of inspection and renovation of tank dikes, and the like.
2. Proper Disposal of Industrial Waste
In entrusting contracted disposal of factory waste, the individual facilities select the contractors after carefully checking their business licenses.
Also, through consignment contract with appropriate disposal contractors, the Group promotes the recycling of industrial waste, creation of monetary values out of waste, and reduction of waste emissions.
Profits from the creation of monetary values out of waste are donated to the Japan Eye Bank Association, for instance, which is one of the Group´s various activities of social contributions.
3. Reduction of water consumption
As part of its efforts at effective use of natural resources, the Group companies are endeavoring to reduce water consumption by circulating the water used in the manufacturing process.
4. Energy saving and power saving activities
As part of the actions for energy saving and power saving, each of the facilities is pushing ahead with the replacement of lighting fixtures with energy-saving type luminaires.
At each of the Group´s production bases, efforts are being made for energy saving by reviewing the current status of energy use and devising more efficient mode of operation.
Also, efforts are being made to replace the existing equipment with the energy-saving type equipment in an appropriate order.
