1. Energy and Resources

1) Energy

CO2 emission volume and energy intensity in Japanese factories

Note) CO2 conversion formula: CO2-ton = C-ton x 3.67

Transition in production output in Japan

Note 1) CO2 emission volume and water consumption are affected by changes in production output.
Note 2) Taking effect from fiscal 1999, the BUGGY that used to be classed as a Power Product has been re-classed
as a Motorcycle.

Carbon dioxide emission at the factories in fiscal 2000 was recorded as 13.79 C-10.000tons the target of 13.40 C-10.000tons(a 1.6% increase against FY1999 and a approximately 18% decrease against FY1990). Unit energy consumption was recorded as 13.87 kl/100 million yen as compared with the target of 13.49 kl/100 million yen. Although the increase in production output as compared with the production plans did have an effect, unit energy consumption was approximately 4% down on fiscal 1999.
The following energy saving efforts were sustained also in fiscal 2000.


	Introduction of inverter control for pumps and motors Reduction in air supply pressure Expansion in the efficient utilization of waste heat Reducing inefficiencies in the production processes

On the paint coating line newly commissioned at the Suzuka Factory in fiscal 2000, it was possible to achieve a substantial improvement in energy efficiency as a result ofthe efforts described below.

Energy Saving Efforts at the Paint Coating Line at the Suzuka Factory

Creating a more compact process as a whole

Reducing the number of robots thanks to the use of self-propelled, multi-axis robots, etc.

The engine production lines for the ''Accord'' and ''LEGEND'' were transferred from the Wako Plant to the Sayama Plant in an attempt to improve productivity and reduce energy consumption.
Further efforts will be made to save energy in all processes by using the LCA technique.

2) Resources (Water Consumption)

Water consumption and water intensity in Japanese factories

Note : Water consumption is affected by changes in the production output.

Water consumption per unit production value at the factories in fiscal 2000 showed a slight decrease in term of the index figure which was 106.7, a 0.3% reduction as compared with the previous year. The practice of recycling water has been established for a long time in the production processes in order to minimize effluent discharge through repeated recirculation. In addition, new measures to save and conserve water in a more consistent manner have been taken. In addition, there has also been an increase in the use of rainwater.

Water Saving Measures

Reuse of washing water in the paint coating process

Recirculation of cooling water

Extended secondary use of treated water and use of more sophisticated
water treatment
