At our factory in Thailand, we are actively working to conserve energy (electricity) as part of our commitment to environmentally friendly technology initiatives. In 2019, we installed solar panels to reduce CO₂ emissions and contribute to global environmental protection. Monitors installed within the factory allow us to visualize daily energy consumption and solar power usage, helping to enhance employees’ environmental awareness. All employees are working together toward “production that stays one step ahead,” with a strong focus on environmental responsibility, carbon neutrality, and the Sustainable Development Goals (SDGs).
