  Each factory is reviewing and improving its energy conservation system under the guidance of the Environment and Safety Measure Headquarters' Policy.

	Goal	Results	Evaluation
1	Reduction of carbon dioxide gas (CO2) emission level to 90% of FY 1990 level by FY2010.	95% compared to FY1990	△
2	1% annual reduction of energy consumption rate over the previous fiscal year measured in crude oil equivalent.	6% increase over previous FY	×
3	Midterm goal: Reduction of energy consumption rate to 90% of FY 1990 level by FY2010.	97% compared to FY1990	△

1. Promoting CO₂ Emission Reduction

  Asahi Denka Group is working to achieve CO₂ emission reduction target of FY2010. Emissions of overseas companies are also counted from 2003.
(1) The CO₂ emission level in FY2004 was 183,198tons, 1,013 ton (0.6%) increase over 182,185 tons of FY2003.
(2) Asahi Denka Co., Ltd. achieved emission reduction, as FY2004 emission level was 95% of FY1990.
(3) Total emission level of the 5 greenhouse gases (GHGs), other than CO₂, defined in the Kyoto Protocol* amounted to 109 tons, in CO₂ equivalent. Total GHGs emission was 183,307tons.

2. Promoting Energy Conservation

  Asahi Denka Group has been working on energy conservation efforts. Consumption Level in Crude Oil Equivalent:

Energy consumption in crude oil equivalent
  Energy consumption (in crude oil equivalent) of FY2004 was 73,301kl, which was 1,462kl (2%) increase over 71,839kl of FY2003. This increase is due to an increase of production that requires high energy consumption. Substantial reduction of energy consumption due to facility and management improvement was 3,636kl（5%）measured in crude oil equivalent.

3. Manufacturing Sector

a. Energy Consumption Rate in Crude Oil Equivalent（Consumption Level in Crude Oil Equivalent(kl)/ Production Quantity(t)）
  Energy consumption rate in FY2004 was 0.179kl/ton, in the crude oil equivalent, which was roughly 6% deterioration over the 0.169kl/tons of the previous fiscal year. Major reasons for such an increase were an increase of production that requires high energy consumption and a closure of low energy consuming production processes, resulted in 9% reduction of production quantity.

b. Index of Energy in Crude Oil Equivalent（The Asahi Denka Co., Ltd. Manufacturing Sector）
  The Asahi Denka Co., Ltd. index of energy in crude oil equivalent in FY2004 was 97 over FY1990 representing a 100 index. It was deteriorated, compared to 91 of the previous year. The FY2010 goal is to achieve energy index of 90, in crude oil equivalent.

4. Non-Manufacturing Sector

  From FY2001 the statistics of the research laboratories, headquarters, branch offices, sales offices and extension offices have been aggregated in the results.

5. Group Company

  The energy consumption by the group companies in FY2003 was 2,213kl, in crude oil equivalent, 3% of the entire company. The energy consumption by the overseas manufacturing sector companies was 2,955kl, in crude oil equivalent.

6 . Energy Conservation Practiced at Each Factory

■ Promotion of Global Warming Countermeasures
  In 2004, “Energy Conservation Promotion Subcommittee” was organized. Various departments, including those of group companies exchanged opinions there.

■ Management Activities

1. Sohma Factory  Steam consumption was reduced by 120t, by increasing batch size of production facility and improving reduced pressure aspiration pattern of draining process that resulted in reduced aspiration time.
2. Fuji Factory  Leakage from compressed air piping was investigated using air leak detector. Thirty leaks were found and repaired.
3. Akashi Factory  An energy conservation plan for the whole factory is being made, following energy consultant guidance and a proposal made by a gas company. “Energy conservation proposal” competition was carried out among employees of all group companies. Such a competition also helps raise the awareness of employees.

■ Facility Improvement

1. Kashima Factory  Electric power loss was reduced to 288 MWh/ year from 878 MWh/ year (590 MWh/ year, 67% reduction), by introducing a world class highly efficient electric transformer with NEDO* support program subsidies. The transformer enables 99.75% transformer efficiency.

2. Mie Factory   Steam consumption rate improved by 4.9% and CO₂ emission was reduced by 1,950t over the previous FY, as fuel was changed from heavy oil to manufactured gas with boiler renewal. Electric power consumption was also reduced by 35,000kWh by introducing inverter to coolant water pump.
3. Chiba Factory  Air compressor was renewed to screw* type from reciprocating* type. Heatless* dehumidification machine was introduced. Steam consumption was reduced by 3,400t, by optimizing steam consumption with increased steam ingredients warming rooms.
