⚡ Energy Management

By managing indoor lighting levels and operating high-efficiency equipment, we reduce unnecessary power consumption and systematically practice everyday energy-saving activities.

🌿 Greenhouse Gas Emissions Management

We strictly control air pollutants and hazardous chemicals in the workplace, and work to minimize carbon emissions from production through more efficient processes.

♻️ Waste Management

In accordance with our workplace waste management guidelines, we separate waste thoroughly from the point of generation and follow the designated treatment standards to raise our waste recycling rate.

📊 Greenhouse Gas Emissions Analysis

  • ☞ Total emissions in 2025 were 1,108.577 tCO₂.eq, an increase of 18.05% from 2023. Kerosene emitted 0.125 tCO₂.eq for the first time in 2025, and LPG and waste emissions rose for three consecutive years.
  • ☞ Diesel emissions fell in 2024 and rebounded in 2025 (43.983 tCO₂.eq), which is presumed to be due to increased vehicle operation from expanded production. Gasoline is also presumed to have been affected by changes in the operation of business vehicles.
  • ☞ The largest share comes from Electricity (Scope 2) , which rose sharply in 2025 (825.200 tCO₂.eq) in line with production volume. It will therefore be designated a “priority reduction target”, and we plan to introduce systematic energy-efficiency measures.
