Energy Conservation
Saving energy through actions large and small
Epson is carrying out upwards of 1,000 separate actions to reduce CO2 emissions. Conducted at all Epson sites,
these actions range from simple measures, such as turning off unneeded lights, to complex actions, such as complete overhauls of production equipment.
Last year we re-examined the use of cleanrooms at one of our manufacturing plants in China. Seeking to reduce the amount of energy needed to maintain the cleanrooms, we took stock of all the operations being conducted in a cleanroom environment. We then selected only those operations that require cleanroom conditions and transferred all the rest to an ordinary plant with far lower energy requirements. By analyzing airflows and tweaking operations to maximize efficiency, this manufacturing plant succeeded in maintaining the required cleanroom class for the only work that needed it, molded parts ejection. These actions enabled us to slash the plant s annual CO2 emissions by 300 tons, or 88.8%. The number of years needed to earn a return on investment: 0.85.
from business activities. By the end of FY2003, all Epson sites and companies in Japan and all Epson manufacturing companies outside Japan had achieved Level 1. Sites that recently came under the Epson umbrella are also working to reach Level 1.
We are now shifting as a company toward actions to reach Level 2, which targets improvements in production processes. In Level 2, the aim is to reduce resource inputs by keeping an eye out for opportunities to reuse a factory s waste on-site as an ingredient in the manufacturing process.

Zero Emissions
Recycling wastes and reducing resource inputs
Epson instituted a zero emissions program to promote the effective use of resources, reduce waste levels, and help extend the lives of final disposal sites.
Our zero emissions program is carried out on two defined
