We value environmental stewardship and strive to continue to adopt sustainable business practices that help manage our operational risks and opportunities, protect the environment and safeguard our employees and communities.

We are subject to a variety of environmental, health and safety laws and regulations in each of the jurisdictions in which we operate, governing, among other things, air emissions, wastewater discharges, the generation, use, handling, storage and disposal of, and exposure to, hazardous substances (including asbestos) and waste, soil and groundwater contamination and employee health and safety.

We have a dedicated team in charge of environment, health and safety (“EHS”) matters, called ESH (Environment, Safety and Health) team, that establishes and reviews internal EHS regulations based on international agreements and local laws and regulations to create a safe and healthy workplace for our employees and to protect the environment, while complying with laws and regulations of the jurisdictions in which we operate. We have obtained various EHS certifications, including ISO 14001 and ISO 45001, and process safety management (PSM) from global certification organizations.

Emissions and Energy Consumption

Since 2015, our Korean operating subsidiary has been subject to a new set of greenhouse gas (“GHG”) emissions regulations, the Korean Emissions Trading Scheme (“K-ETS”), which was promulgated under the Act on Allocation and Trading of Greenhouse Gas Emission Allowances (the “Act”). K-ETS has set GHG emission targets such that the emission level of 2018 would be cut by 40% by 2030 and carbon neutrality would be achieved by 2050. The following table shows our “Emissions and Energy Consumption” for the periods presented calculated in accordance with the Act:

We strive to reduce our energy consumption including GHG emissions in alignment with these targets. We regularly implement energy conservation and consolidation projects and hold internal meetings to discuss implementation status, monitor performance and secure new investments to improve energy efficiency.

Water Management in Manufacturing

Water is an essential resource in our manufacturing processes. While we are not located in “High or Extremely High Water Stress” regions according to the World Resource Institute’s Aqueduct Water Risk Atlas, we are keenly aware of global and local water concerns. We carefully monitor water usage at our sole manufacturing site located in Gumi, South Korea, and routinely set goals to conserve water.

Water reuse and recycling is a key aspect of our water conservation efforts. Reclaimed wastewater is a high-quality, purified substitute for freshwater, whose use in manufacturing can significantly reduce environmental impact. Our manufacturing site uses reclaimed wastewater that has been discharged from nearby sites and purified at a wastewater treatment plant.

Waste Management in Manufacturing

We recognize the environmental risks associated with semiconductor manufacturing processes, and we responsibly manage the use and disposal of materials and chemicals to protect the environment and our people. We utilize our own waste management database and work with waste treatment specialists who focus on eliminating pollution at source and promoting recycling.

Environmental Compliance and Supplier Engagement

We strive to deliver higher corporate value based on all stockholders’ confidence through the ethical environmental management system and environment protection activities. Our objectives are embedded in our Environment, Safety and Health Policy, which can be found below:

ESH Policy


We adhere to an increasing number of laws and regulations, including the EU Restriction of Hazardous Substances (RoHS) Directive, the U.S. Conflict Minerals Rule (see below) and Korea’s Act on the Registration and Evaluation of Chemicals (K-REACH), that are applicable to our manufacturing process, as well as those of our suppliers where applicable. Before introducing hazardous substances to our processes, we screen new incoming chemicals and verify their environmental compliance in accordance with our pre-approval policy.

Procedure for Introducing New Chemical Substances

RoHS-3 Compliance Self-Declaration  Halogen-Free Self-Declaration


We support the goals and initiatives of Section 1502 of the U.S. Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Conflict Minerals Rule”), which aims to dissuade the use of any conflict minerals that directly or indirectly finance or benefit armed groups on Democratic Republic of the Congo (“DRC”) or adjoining countries. This includes the minerals tin, tungsten, tantalum, gold and certain of their derivatives, but may also expand in the future to cover other minerals and derivatives. We are committed to complying with the reporting obligations required under the Conflict Minerals Rule. We undertake reasonable due diligence with respect to our supply chain to ensure that conflict minerals are not being sourced from mines in the DRC or adjoining countries and reserve the right to require that suppliers provide reasonable evidence of their own due diligence. For more information on our conflict minerals, please refer to our Conflict Minerals Reports:

We establish, operate and manage our own standards for EHS matters. For more systematic green management activities, ISO 14001 and ISO 45001 (Environmental Safety and Health Management System) have been introduced and operated by DQS KOREA, an international certification agency, since 2004. We also practice compliance with domestic laws such as PSM operation, and we have applicable domestic business licenses for hazardous chemicals.
