Measures against Climate Change

Climate change is a pressing issue for each and every person or organization that uses energy. JAE Group companies are working hard to conserve energy by effectively utilizing electric power, fuel, and other energy sources.

Efforts at group companies have thus far centered on facility-related measures, such as air conditioning and lighting, but starting in FY 2009, measures that emphasize energy-saving efforts in production are being taken.

Greenhouse Gas Emissions

Total CO2 emissions from the domestic JAE Group were some 33,250 tons, a 2.8% increase over FY 2008.
The rise in emissions was due to the operation of new facilities, including an anechoic chamber and material analysis center at the Akishima Plant and the opening of a new plant that expanded JAE Hirosaki's production space by 1.7 times, while at the same time emergency measures had to be taken. These included not only the measures against climate change at each site, but also the reduction of facility operating times due to the economic downturn.
In FY2009, although we had targeted a 39% improvement, which exceeds the common goal under the voluntary action plan (in the electric/electronics industry) advocated by the Japan Business Federation, i.e., a 35% reduction over FY 1990 in the average emissions per unit of real sales by 2010, the slumping economy hampered the effort, resulting in an improvement of 31.4%.
The group cut 2,310 tons of CO2-equivalent emissions in FY 2009 by such means as facility-related measures, such as adding inverters to fluorescent lighting and all types of pumps at plants, and production-related measures, such as improving production efficiency.
Starting in FY 2010, the Akishima Plant will be obligated by the Tokyo Metropolitan Government to reduce its greenhouse gas emissions by more than 6% over five years, and the group plans to respond to the challenge with systematic measures.
Fighting climate change is still a crucial issue in the group's environmental policy in FY 2010, and it is actively involved in reducing CO2 emissions by effectively deploying measures at each site across the entire group.
* Average CO2 emissions per unit of real sales = CO2 emissions divided by real sales.
Real sales is an indicator adjusted for the steep drop in prices in the electrical/electronics industry, and is obtained by dividing sales by the Bank of Japan's domestic corporate goods price index (in the field of electrical equipment).
Real sales = sales divided by the domestic corporate goods price index (electrical equipment)

Main Energy Saving Policy for FY 2009

Introduction of high-efficiency lighting (JAE, HAE)
Replacing the old two-lamp lighting fixtures with single lamp high-efficiency fixtures cut the power used for lighting without a change in lighting intensity.
Switch to vacuum pumps for assembling facilities (HAE)
Switching from the ejector-type pumps that used compressed air to vacuum pumps for conveying parts reduced the amount of compressed air used, resulting in an overall reduction in power usage, including that for air compressors.
Introduction of air-conditioning heat pump chillers (HAE)
Switching from oil-fired cool water units to high-performance air-conditioning heat pump chillers for plant air conditioning cut CO2 emissions.
Promotion of inverter control for fans and pumps (JAE, HAE, YAE, SAE)
Promoting the switch to inverter control for the fans and pumps of air-conditioning facilities and production facilities cut energy usage by improving their operating efficiency.
Improvement of clean room air-conditioning operation (JAE)
Energy usage is being reduced by revising the operating status of air-conditioning when it is not being used in clean rooms that are not in use, for example, at night, and curtailing the operation of air-conditioning facilities in areas where it will not affect quality.
Introduction LED lighting (SAE)
As the first stage of introducing LED lighting, which has low power consumption, emergency exit lights that previously used fluorescent lamps are being switched to LED lighting.
