Each plant 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. | 96% compared to FY1990 | Δ |
| 2 | 1% annual reduction of energy consumption rate over the previous fiscal year measured in crude oil equivalent. | 0.6% increase over previous FY | Δ |
| 3 | Midterm goal: Reduction of energy consumption rate to 90% of FY 1990 level by FY2010. | 97% compared to FY1990 | Δ |
*Note that items 1 and 3 are results of the Production Sector at ADEKA Co., Ltd.
1. Promoting CO2 Emission Reduction
ADEKA 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 FY2005 was 185,351tons, 2,153 ton (1.2%) increase over 183,198 tons of FY2004. |
| (2) | ADEKA Co., Ltd. achieved emission reduction, as FY2005 emission was 177,668 tons, 96% of FY1990. |
| (3) | Total emission level of the 5 greenhouse gases (GHGs), other than CO2, defined in the Kyoto Protocol*1 amounted to 121 tons, in CO2 equivalent. Total GHGs emission was 185,472tons. |
*1 Kyoto Protocol:
Kyoto Protocol was ratified at the 3rd Conference of the Party (COP3) to the UN Framework Convention on Climate Change (UNFCCC) in 1997. Developed countries agreed to reduce GHGs using emission level of 1990 as a basis.

2. Promoting Energy Conservation
ADEKA Group has been working on energy conservation efforts.
♦ Energy Conservation Practiced at Each Plant
Promotion of Global Warming Countermeasures
Infrared thermometer use (thermography) was introduced and heat emission was analyzed in FY2005.
Management Activities
(1) Kashima Factory
Infrared emission from specific objects is detected. This was converted into an actual temperature. Temperature distribution was then visually displayed and analyzed.
(2) Mie Factory
Individual awareness on energy conservation has been raised. As a result energy management has been implemented properly. Inspection results show that energy management criteria were met in each production process.
(3) Fuji Factory
"Energy Conservation Group" in cooperation with ESCO*2 companies carried out energy conservation initial checks of facilities and promoted ESCO programs.
(4) Energy Conservation Awareness-raising Using Poster
A poster to promote energy conservation awareness raising was produced and displayed at each factory and office, during "Energy Conservation Month" in February promoted by the Ministry of Environment.
Facility Improvement
(1) Kashima Factory
In order to reduce steam usage, facility re-installment from steam trace to electro thermal trace*3 has been put into progress. Trapping of steam has been examined by producers and all defective traps were replaced. In order to prevent leakage from steam pipes, thorough maintenance was ensured.
(2) Akashi Factory
In order to reduce load current, for energy conservation purposes, water was sprinkled upon high pressure condensing units of freezers and refrigerators. Heat release efficiency was improved, resulting in an energy reduction of 21,000kWh Insulation of the factory ceiling was improved resulting in expected conservation of 22,000kWh.
♦ Consumption Level in Crude Oil Equivalent
Energy consumption (in crude oil equivalent) of FY2005 was 73,641kl, which was 340kl (0.5%) increase over 73,301kl of FY2004. Substantial reduction of energy consumption due to facility and management improvement was 1,240kl (1.7%) measured in crude oil equivalent.
♦ Manufacturing Sector
(1) Energy Productivity Rate in Crude Oil Equivalent
Consumption Level in Crude Oil Equivalent(kl)/ Production Quantity(t)
Energy productivity rate in FY2005 was 0.180kl/ton, in the crude oil equivalent, which was roughly 0.6% deterioration over the 0.179kl/tons of the previous fiscal year. Major reasons for such an increase were an increase of production that requires high energy consumption.
(2) Index of Energy in Crude Oil Equivalent
The ADEKA index of energy in crude oil equivalent in FY2005 was 97 over FY1990 representing a 100 index. It was the same as the previous year. The FY2010 goal is to achieve energy index of 90, in crude oil equivalent.
♦ 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.
♦ Group Company
The energy consumption by the group companies in FY2005 was 2,147kl, in crude oil equivalent. The energy consumption by the overseas manufacturing sector companies was 3,463kl, in crude oil equivalent.
*2 ESCO program:
ESCO (Energy Service Company) Energy Service Company, ESCO program is a business in which private companies offer comprehensive services regarding energy conservation. Their services include initial check on energy conservation potential, planning and implementation of energy conservation measures, maintenance of facilities, and their financing.

*3 Electro thermo trace:
For heating and heat retention of pipes, electro heater wires are used, instead of conventional methods, which include usage of steam and hot water trace or double pipe. With such a new method the switching on and off of heating systems and adjustment of temperatures has become easier, leading to better temperature adjustment.
