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, according to a company spokesperson. In the U.S. for example, Hoya’s Ramsey, Minnesota facility uses 100 percent renewable energy certificate from Connexus energy that supports their solar farm and local honeybees.

Internationally, the Hoya Group has been structuring a globally-operated management system based on ISO (International Organization for Standardization) 14001 and ISO45001 with the purpose of promoting the environmental protection activities by the employees and ensuring the safety and health of the employees. As of February 2020, the certification is being applied to 53 sites in 19 countries.

Reducing CO2 Emissions
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. It sets a group-wide reduction target for CO2 emissions and is directing its environmental protection activities toward accomplishing it.

Additionally, the Group has been practicing various environmental burden reduction activities under its Environmental Philosophy and Fundamental Environmental Policies. These include:

- Soil pollution control measures, underground water pollution
- Control measures, hazardous substance leak control measures
- Proper disposal of industrial waste
- Reduction of water consumption
- Energy saving and power saving activities

Hoya has also undertaken 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.





Hoya established an international consortium with Hoya Lens Vietnam Ltd. (HOLV), a subsidiary in Vietnam in August 2016, and introduced energy-saving equipment utilizing subsidies from JCM equipment subsidized business system by April 2018. The Group began initiatives to reduce greenhouse gas emissions in Vietnam starting in June 2018.
