We will comply with regulations and follow the Sony Group Environmental Vision.To reduce environmental impact through our activities, we will aim at the industry-leading environmental performance, and to create the profitable era from the environmental contribution.
Sony Semiconductor Solutions Group are aimed at reducing environmental impact reduction activities such as energy conservation and other activities at relevant sites, in line with Green Management 2025 – a set of environmental mid-term targets to achieve by fiscal 2025. Furthermore, we develop the regional activities focusing on contribution to the environment in response to local needs (including the activities for environmental conservation inside the sites).
Powerful fans forced chilled air from the ceiling, to cool the entire room and the machinery, with waste heat being sucked through vents in the floor.
The new system uses natural convection, with chilled air entering at the floor level, where heat-producing machinery is. Warm air then naturally rises to the ceiling to be recycled, carrying dust particles with it away from the work surfaces.
Optimising airflows for improved efficiency
The new system has reduced CO2 emissions by about 67% compared with the previous system, from approximately 4,000 tons to approximately 1,300 tons. Newly introduced HVAC (Heating, ventilation, and air condition) units control airflow more efficiently by directing air at production machines. The new airflow strategies also shift unwanted dust to the ceiling and away from production areas.

Plans are in place to install solar panels on the entire roof of the 4G building. Construction is scheduled to commence in February 2024, with the goal of initiating operations within the same year. The total area, including operational panels, will span 46,200 square meters.
