Contribution to building an IoT/ ICT-driven society

Reducing environmental impact

Responding to climate change

Increased development difficulties associated with the rapid upgrading of technologies required by the market (Advanced Materials)Intensified competition in high-value-added products and devices (Optoelectronics)

In the event that the appropriate response is not taken:

Air pollution and water pollution arises in the environment near the plantsReputational damage

Transition risks

Introduce an impact fee system for carbonIncrease research and development spending and capital investment to achieve carbon neutralityChange the recycling collection environment, etc.

Physical risks

Impact of accidents at cement plants, etc.Increase in semiconductor demand due to progress in automation and unmanned technologies in each industry (Advanced Materials)Increase in demand for high-capacity, high-quality transmission optical communications associated with the increase in data transmission volumes (Optoelectronics)Growing demand for energy-saving and power-saving devices (Optoelectronics)Preserve the environment in the vicinity of cement plantsContinued operation of plants

Transition opportunities

Reduce coal consumption and promote energy savingsCreate new businesses and carbon businessesRecycling market: Advancements in recycling technologies and an increase in accepted productsOptoelectronics business and Advanced Materials business: Increased demand for optical communications components and semiconductor manufacturing equipment components, etc.

Physical opportunities

Increase in demand for infrastructure due to measures for national resilience, and increase in the maintenance, renewal, and repair of concrete, etc.Increase in demand for marine products due to heightened social interestEnhance production facilities for electrostatic chucks (Advanced Materials)Strengthen development and production systems through an increase in personnel (Advanced Materials)Advance into the 1.2T/1.6T market for optical communications equipment LN modulators (Optoelectronics)Take measures to prevent air pollutants contained in gas emissions, and keep emissions below legal standards (Cement)Prevent water pollution (sedimentation tanks, oil-water separation tanks, oil monitors)Identify water intake and discharge by source and respond to water risksImplementation framework centered on the Sustainability CommitteeConsider potential revisions to SOCN2050Undertake various research and development activities with the goal of creating new businesses
