Energy Saving

The Panasonic Group has initiated a new index, "size of contribution in reducing CO₂ emissions" since FY2011 and tackled continued activities to improve our energy saving constitution. The Company achieved 940,000 tons of size of contribution in reducing CO₂ emissions in FY2012.

Size of contribution in reducing CO₂ emissions

The size of contribution in reducing CO₂ emissions is defined by the following formula;
CO₂ reduction contribution during the applicable fiscal year (base: FY2006) = (Basic unit per production of FY2006 - Basic unit per production of the applicable fiscal year) X Production output of the applicable fiscal year

Major activities

• Establishment of the CO₂ Reduction Promotion Committee
• Information sharing, horizontal spread and high standardization between each operational site
• Performance control and steady promotion of plans by visualizing the performances
• Strengthening energy saving activities in the overseas operational sites

Case examples of energy saving activities

The CO₂ emissions reduced in FY2012 were 47,000 tons (4% in emissions) through efforts including the energy saving measures listed below that were globally promoted.

1. Introduction of high efficient equipments
   • Introduction of electric typed module chillers and inverter compressors
   • Adoption of electrification on molding machines
   • Adoption of LED lights
2. Thoroughgoing elimination of wasteful energy
   • Stoppage of power during non production hours such as night time or non-work day
   • Countermeasures on air and steam leakages
   • Adoption of heat insulation and recovery of exhaust heat
   • Thinning out of lights or optimization of illuminance
   • Reduction the unit of vending machines
3. Improvement of process and productivity
   • Lowering the oven temperature or reducing process by changing materials
   • Improving cycle times and yields for production machines
   • Increasing the number of dies
4. Improvement on control methods
   • Adoption of inverter system for air conditioning fans and pumps
   • Applying unit control for compressors and refrigerators
