CSR / Environment

Sustainable Development Goals(SDGs) were adopted by United Nations in 2015. To achieve the 17 targets of SDGs by 2030, business sectors are expected to play a big role in innovation to solve the global environmental issues, such as water, energy, sustainable production and consumption and climate change.

We aim to realize a smart society with our customers, and we contribute to the innovation to solve social and environmental issues in order to achieve SDGs by providing customers with technology platforms based on our strengths in semiconductors applied to “automobile” and “IoT”.

Responsible Minerals Sourcing

Human rights violations and forced labor related to conflicts in the Democratic Republic of the Congo (DRC) and its neighbors are drawing international attention. Particularly, it is concerned that the exploitation of mineral resources in these areas could lead to fund armed groups engaged in conflicts.

In response to this situation, the “Dodd-Frank Wall Street Reform and Consumer Protection Act” was established in the United States in 2010. The act identifies tantalum, tin, gold and tungsten (3TG materials) and other minerals specified by United States Department of State, as “conflict minerals”. Under this act, companies listed in United States’ stock exchange are required to report their usage record and the country of origin regarding conflict minerals produced in DRC and its neighboring countries.

As a member of United Microelectronics Corporation (UMC), United Semiconductor Japan Co., Ltd. (USJC) strives for responsible minerals sourcing and prohibits to use 3TG materials relating to conflicts and human rights violation which come from DRC and its neighbors. USJC exercises due diligence to check whether upstream smelters/refiners of the suppliers utilize conflict minerals. We use Conflict Minerals Reporting Template (CMRT) and Cobalt Reporting Template (CRT) developed by the Responsible Minerals Initiative for the due diligence.

USJC expects our suppliers to support our policies and corporate on the due diligence. We strive for avoiding the use of conflict minerals to prevent human rights violations and violence with responsible minerals sourcing throughout our entire supply chain.

USJC will reasonably disclose information to customers and other stakeholders upon their request regarding our policies of responsible minerals sourcing, the use of minerals, and other related matters.
