Energy Saving Activities

Major challenges

  • Sharing energy saving case examples and promoting optimum standardization by using energy saving committee and intranet
  • Steady promotion of business plan with performance management and visualization
  • Reinforcement of energy saving activities at overseas sites

Energy saving case examples

Our Company promote following activities on global basis, reducing CO2 emissions.

  1. Installation of PV power generation system
