Environmental Indicators and Calculation Formulas

The Ricoh Group aims to establish an environmental accounting system that can serve as an effective tool for evaluating economic and environmental efficiencies so as to assist performance and decision-making regarding sustainable environmental management.

Environmental Management Indicators

Environmental management indicators must accurately evaluate the status of sustainable environmental management and facilitate further improvement. To this end, indicators should be set based on the three elements shown below:

1Economic Benefits of Environmental Conservation Activities

Indicating whether activities in environmental conservation are economically rational

Economic benefits/Environmental conservation costs

Activities in sustainable environmental management can be considered economically rational if the quotient is one or greater (i.e., the economic benefits are equal to or greater than the environmental conservation costs).

 
Economic benefits + social cost reduction/Environmental conservation costs

Activities in environmental conservation can be considered economically rational if the quotient is one or greater (i.e., the sum of economic benefits and social cost reduction is equal to or greater than the environmental conservation costs).

 
Environmental impact reduction/Environmental conservation costs

This equation is used to evaluate the efficiency of environmental improvements made by the project/investment activity concerned.

 

2Environmental Efficiency of Business Activities

Indicating the environmental impact of business activities and whether those activities respond to public needs and expectations is justifiable.

Sales/Total environmental impact(physical or monetary amount)

This equation is used to evaluate the environmental impact and whether it is appropriate in relation to the size of the business.

 
Value-added business activities/Total environmental impact(physical or monetary amount)

This equation is used to determine whether the business activity generates an appropriate level of profit in relation to its environmental impact.

 

3Environmental Management

Indicating whether environmental management processes, such as internal audits, site reporting, development of environmental technologies, environmental labelling, and green procurement, are appropriate or not.

 

Objectives of environmental accounting include functioning as a tool to measure the economic efficiency of environmental conservation activities and the environmental efficiency of business activities, as mentioned above. The Ricoh Group's corporate environmental accounting system is designed and operated as an effective tool to evaluate such efficiency levels throughout the Group.

Environmental Accounting Indicators

The Ricoh Group has developed and adopted indicators to evaluate, analyze, and disclose the environmental conservation efficiency of business activities, both individually and collectively. Our progress in environmental impact reduction can be quantified with the Eco-Improvement (EI) value and the Eco-Improvement Index (EII). The EI value shows how much environmental impact (itemized) is reduced by the environmental conservation cost of 100 million yen, while the EII represents the efficiency of environmental impact reduction activities.

Indicators

Eco-improvement value (EI Value) = Environmental impact reduction amount/environmental conservation costs (ton/hundred million yen)

To determine how much environmental impact per ¥100 million in environmental conservation costs is reduced for each environmental impact item

Eco-ratio = Gross profit/environmental impact amount (ton/hundred million yen)

To determine the amount of value-added from business activities obtained per one-ton equivalent of environmental impact discharged

Eco-improvement index (EII) = Total environmental impact reduction amount (1)/Total environmental conservation cost amount (thousands of yen)

Improvement ratio of social cost (IRS) = Total social cost reduction amount (2)/Total environmental conservation cost amount (thousands of yen)

To determine whether the reduction in ((1) environmental impact/(2) social cost) is efficient

Eco-index = Gross profit (thousands of yen)/total environmental impact amount (1)

Ratio of profit to social cost (RPS) = Gross profit/total social cost (2)

To determine whether any profit is made when a company conducts business activities at the appropriate level ((1) environmental impact/(2) social cost)

Eco-efficiency index (EEI) = Sales (thousands of yen)/total environmental impact amount (1)

Ratio of sales to social cost (RSS) = Sales/total social cost (2)

To determine whether a business activity at the appropriate level ((1) environmental impact/(2) social cost) is suitable for its scale

Ratio of eco effect (REE) = Environmental effect (total economic benefit + total social cost reduction amount)/total environmental conservation cost

Ratio of eco profit (REP) = Total economic benefit/total environmental conservation cost

To determine whether an environmental conservation activity is conducted in an economically rational way

Costs

Costs refer to expenditure on environmental conservation activities (in a broad sense), and consist of environmental investments and environmental costs (in a narrow sense).

Environmental Investments
These investments correspond to "Investments in fixed assets" in financial accounting. The amount of environmental investments is distributed as environmental costs over the service life of fixed assets in accordance with depreciation procedures.

Environmental Costs
These environmental costs correspond to the "period cost" in financial accounting. (Depreciation cost of environmental investments is included.)

Economic Benefits

Economic benefits refer to benefits that were obtained by environmental conservation activities and which contributed to the profits of the Ricoh Group in some form. Economic benefits are classified into five categories as follows:

Substantial effect :
This means economic benefits that fall into either of the following two cases:
1)  Cash or cash equivalent is received as a benefit. This corresponds to "realized gain" in financial accounting.

2)  The amount of savings in such costs that would have occurred if environmental conservation activities had not been conducted. This amount is not recognized in financial accounting.
Estimated substantial effect :
Substantial contributions to sales or profits whose value cannot be measured without estimation. They include improving the environmental performance of a product, which leads to an increase in sales or profit.
Secondary effect :
The expected amount of contribution in the case that expenditure on environmental conservation activities is assumed to have contributed to profits for the Ricoh Group. If environmental conservation costs are assumed to be costs that are indispensable for the Ricoh Group to conduct its operations, for example, it can be safely said that such costs contribute to profit in some form. In practice, out of the effects generated by environmental conservation activities, those which do not appear as an increase in sales or profit or a reduction in costs are represented in monetary value calculated by the formula specified for each item.
Incidental effect :
Expenditure on environmental conservation activities can help avoid the occurrence of environmental impact. Therefore, it can be safely said that the expenditure contributed to the avoidance of such damage of environmental impact that would have taken place without the expenditure. In practice, the incidental effect is computed by multiplying the expected amount of damage by an occurrence coefficient and impact coefficient.
Social effect :
Social effect means such effect that is generated by expenditure on environmental conservation activities not for the Ricoh Group but for society. In practice, social effect means the amount of reduction in the expense of electric power and waste disposition that is enabled through environmentally-friendly products for customers.

Effect Calculation Method

Principal methods for effect calculation are shown below.

Formula of substantial effects

Reduction in heat, light, and water cost
Heat, light, and water expenses in the previous year - heat, light, and water expense in the current year
Reduction in waste disposal cost
Waste disposal expenses in the previous year - waste disposal expenses in the current year
Sales value of valuable materials
Sales value of valuable materials sorted from discharged matter
Sales of recycled products and parts
Sales of recycled products and parts
Subsidies
Environmental subsidies from the government, etc.

Formula for estimated substantial effects

R&D profit contribution amount
Product gross margin x gross margin contribution rate calculated using environmentally-friendly points

Formula for secondary effects

Contribution to value-added production 
Gross profit on sales x environmental conservation costs / selling, general and administrative expenses, etc.
Effects on media coverage
Area of newspaper advertisement / newspaper page area x advertisement cost per page
Effects of environmental education
Number of people attending internal environmental education seminars x seminar fee for outside participants
Publicity from environmental advertisements
Number of visitors to environmental Web site x unit price of the sustainability report

Formula of incidental effects

Amount of incidental effects  
Standard amount x occurrence coefficient x impact coefficient x continuance coefficient
Items to be calculated 
Areas of improvement to prevent pollution
Standard amount 
Amount set aside for lawsuits, suspension of operations, and restoration
Coefficient 
Occurrence coefficient and impact coefficient to be set according to occurrence frequency and affected extent

Formula for social effects (economic benefits from use of products by customers)

Total electric power 
Electric power consumption of a product x number of products sold
Electric power cost reduction effect 
(Total electric power for old models - total electric power for new models) x electric power unit cost
Waste disposal cost reduction effect 
(Weight of collected products - weight of final waste) x outside disposal unit cost
