Reduction of Environmental Impacts

Stance towards the Environment

The Optex Group develops, manufactures, and sells sensors (security sensors, sensors for automatic doors, and sensors for industrial equipment), LED lighting devices for inspections at factories, and software. Understanding that protection of the global environment is a corporate social responsibility, the Group thoroughly informs all of its employees of the Optex Group's Behavioral Guidelines, complies with environmental laws, standards, etc., and operates businesses in an environmentally friendly manner.

The Group's basic environmental policy is to reduce CO2 emissions through its business activities and provide products and services that help customers reduce their CO2 emissions when they are used.

The Group offers a wide array of products that help reduce CO2 emissions when they are used. For example, sensors detect people and objects and operate machinery and systems only when necessary. They also enable the streamlining of factory lines. The Group will continue to provide products and services that exhibit both economic efficiency and environmental performance to address climate change and otherwise help protect the global environment.

Environmental Contribution through Products

The Optex Group is driving environmental protection activities by providing customers with products and services that lead them to conserve energy.
Each of its products consumes an extremely small amount of electricity. The incorporation of those products in many different corporate activities is believed to contribute greatly to the reduction of greenhouse gas emissions from corporate activities as a whole.

Optex Co., Ltd. proactively works to reduce CO2 emissions from the use of its products. For this purpose, the company has continued to conduct environmental assessments whenever it plans new products. In fiscal 2019, it commenced activities designed to reduce customers' CO2 emissions by encouraging them to use its products. In 2021, it achieved its target of increasing the total reduction of customers' CO2 emissions based on the contribution of its products to at least four times more than the total CO2 emissions from its business activities.

Management of Chemical Substances

Reflecting concerns over the impact of chemical substances on the environment and eco-systems, moves to establish laws regulating use of chemical substances are being strengthened all over the world.
To provide products conforming to laws and standards of countries and regions where they are sold, the Optex Group has established a system under which non-conforming components and materials are not used in or after the product design phase.

To properly identify chemical substances and facilitate communication and information disclosure, the Optex Group collects information applying an industry-standard format. The Group has also established a system for providing the information to stakeholders who need it at the time when they need it.
Further, the Group has established its Green Procurement Standards and shares them with all suppliers to ensure the procurement of components and raw materials with low environmental impact.

Group Companies' Response to Chemical Substance Regulations

When selecting new components, Optex Co., Ltd. and Optex FA Co., Ltd. choose RoHS-compliant components in the design phase. They obtain information about all chemical substances from suppliers and store the information in the chemical substance management system before commercial production. They properly decide whether specific chemical substances are problematic in light of regulations by applying their own green standards to ensure the chemical safety of their products.
Further, Optex Co., Ltd., Optex FA Co., Ltd., and Optex MFG Co., Ltd. have created their common Management Guidelines of Chemical Substances Contained in Products and ensure that they are known to everyone internally and all suppliers.
CCS Inc. has created the CCS Products Environmental Regulations Response Policy to ensure that the company conforms to new regulations. The company has also created the Green Procurement Guidelines and informs its suppliers thoroughly of its policies on the reduction of environmentally hazardous substances and the procurement of conflict minerals.

 Responsible Sourcing of Minerals

There are concerns about child labor, other human rights violations, and environmental destruction occurring in the Democratic Republic of the Congo (DRC) and its adjoining countries related to the minerals mined there, and also fear that these minerals may be a source of funding for armed groups, further aggravating the conflict.
The goal of responsible sourcing initiatives is to avoid the procurement of minerals connected to these issues. These initiatives include initiatives being conducted in line with the U.S. Dodd-Frank Act which reformed financial regulations in 2010.
The Optex Group positions initiatives on this matter as important tasks for the fulfillment of its corporate social responsibility. It is moving forward with initiatives to ensure more responsible sourcing, including the examination of procured materials and components to ensure they do not contain conflict minerals and the establishment of agreements with suppliers that they will not procure conflict minerals.
