Summary of the environmental and social initiatives implemented at the Ohtsu Plant.
1. Environmental Initiatives
- Reducing CO2 Emissions

For each unit replaced, CO2 emissions have decrease by three tons annually. Through September 30, 2009, eighty-six units had been replaced as part of an ongoing upgrade program. In addition, the plant installed inverter conversions for heating, ventilation, and air-conditioning and production equipment, and switched over to large-capacity motors and high-efficiency lighting fixtures.
