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 5-percent reduction of CO2 emissions from the fiscal 2014 level by fiscal 2020 (from fiscal 2016).

CO2 Emissions:

The CO2 emissions of the HOYA Group in fiscal 2018 were 405,770 tons of CO2.

The reduction of CO2 emissions was 19.3 percent in Japan.

The emissions were 6.6 percent increased overseas.

As a result, the emissions were 1.2 percent increased globally.

Over-seas 317,976 328,124 337,960 338,946 6.6% increased

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 and air conditioning equipment with those of energy-saving type.

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.

5. Efforts to reduce greenhouse gas emissions at overseas offices using Joint Crediting Mechanism (JCM)

JCM means contributing to global warming countermeasures through dissemination of excellent low-carbon technologies to developing countries, and at the same time appropriately evaluating the contribution to Japan's emission reduction.

It is a mechanism to utilize it to achieve the reduction targets of Japan.

HOYA establishes an international consortium with HOYA LENS VIETNAM LTD. (HOLV), a subsidiary in Vietnam in August 2016, introduces energy-saving equipment utilizing subsidies from JCM equipment subsidized business system by April 2018.

We began initiatives to reduce greenhouse gas emissions in Vietnam since June 2018.
