Nikon is striving to combat global warming through a range of activities, notably by saving energy and thus minimizing CO2 emission.
The principal measures being adopted are: increasing the efficiency of HVAC and lighting equipment; applying stricter controls on the use of lighting and office equipment; and improving production processes. Additionally, the company is finding ways to harness natural energy sources.
After installing high-efficiency equipment and moving to natural energy sources, Sendai Nikon became the first member of the Group to introduce a co-generation system. Used in combination with high-efficiency equipment, this system is now yielding considerable energy savings. In 2007 the Yokohama Plant co-sponsored a Yokohama city project to generate electricity using a large-scale windmill. It also started purchasing green energy. Tochigi Nikon has installed a lighting system that uses wind and solar power, both natural energy sources.
To improve production processes, a workplace energy-saving diagnosis is conducted by outside experts. This involves the inspection of actual production lines and facilities. Observations and comments by the experts lead to ideas for improvement and to the pinpointing of areas needing study, from which the Group develops concrete measures. Run in tandem with the diagnosis, a staff seminar on energy saving heightens awareness of the issues.
Note: CO2 emissions for the year ended March 31, 2008, have been calculated using the emission index for the previous year.
We intend to implement the following measures as we head into the year ending March 2009.
