Environmental Initiatives

OHARA recognizes that achieving compatibility between corporate activities and the environment is one of the most important issues in running a business.  All employees at the company will build environmental management systems in keeping with international standards, pursue environmental management activities, and contribute to society through business activities in optical glass, specialty glass, and applied products that are compatible with the environment. In terms of environmental activities, we are pushing hard to reduce and reuse leftover glass materials, conserve energy, and efficiently use resources to protect our environment and Earth. 



Under the internationally accepted philosophy of sustainable development, OHARA recognizes that achieving compatibility between corporate activities and the environment is one of the most important issues in running a business. All employees at the company will continue to refine its environmental management systems in keeping with international standards, and to operate in the areas of optics, electronics, environment and energy, effectively harnessing the technologies we have developed for optical glass, specialty glass, and applied products.

Environment Management System ISO14001

In April 2000, OHARA obtained certification under the international ISO14001 standard for environmental management (the certification body was JIC Quality Assurance Ltd.). We attained the environmental objectives and targets and escalated environmental management systems through the Waste Reduction and Reuse Promotion Committee, the Resource Conservation Committee, the Energy Saving Promotion Committee, and environmental management activities at every department. **The scope of application of the environmental management system is as follows.

Approach to Conflict Minerals

It has been an internationally significant issue that serious human-rights abuse is being committed by armed forces in dispute regions, including the Democratic Republic of the Congo and its neighboring countries. Minerals mined in such regions (tantalum, tungsten, gold and tin) are called conflict minerals. There is a concern that conflict minerals would serve as direct or indirect sources of funding for the local armed forces.

With respect to this issue, conflict minerals provisions under the Dodd-Frank Act were enacted in 2010. In addition, the Organization for Economic Co-operation and Development (OECD) issued a Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict Affected and High-risk Areas. Through the above, companies are being strongly required to take responsible initiatives in regards to their supply chains. OHARA has been advancing initiatives towards the non-use of conflict minerals by, for example, conducting surveys on the circumstances of use of minerals in products, in order to fulfill social responsibility in procurement activities.
