Requirements
The environmental impact of electricity purchased from othercompanies should be dealt with as follows for the time being.
1. If the environmental impact of electricity sold to generalelectricity power producers can be determined, it may be
excluded.
2. The environmental impact of electricity purchased from otherelectric power producers shall be considered.
3. If the data for electricity from other electric power producers
cannot be obtained, or if some own-company data (e.g., water
quality related, etc.) cannot be obtained, then convert from theratio of electricity generation.
Converted value = Known value × Total electricity

Coverage1.

For emissions associated with fuel consumption andenvironmental impacts associated with the operation of
own-company facilities, as a rule measured values shall be
used. However, for design values whose basis is clear,calculated values may be substituted.

2.

As a rule, each type of data shall be yearly values.

Cut off rules

When a cut off is applied, this fact shall be made clear, and thereason shall also be made clear.

Selection of basic
units

1. Fuel supply and electricity generation• For each type of fuel, adopt a basic unit using thenecessary unit conversion.
• For limestone, use 1/2 the value of “quicklime”.
2. Facility construction• For steel, adopt “cold rolled steel plate”; for copper, adopt“copper plate”; and for aluminum, adopt “aluminum
plate”.
• For insulating materials, adopt “PE (low density)”.
• For concrete, adopt 1/5 the value of “cement”.
For the above basic units, refer to “List of EcoLeaf basic units”.
