Environmental performance indicator

Basis for calculation

Procurement rate for environmentally conscious products

Value of environmentally conscious products procured divided by value of all products procured
Environmentally conscious products: recycled paper and non-chlorine bleached pulp paper; forest-certified andother paper; biodegradable and recycled film and other plastics; plant oil-based ink, recycled solvents, and otherenvironmentally certified products

Energy consumption (TJ)

Total of all energy consumed annually × calorie conversion factor for each energy type
Calorie conversion factors for city gas are calculated according to the caloric values in Appendix 4, “List of City Gas
Suppliers and Supplied Quantity of Heat” (revised April 15, 2013) of the Requirements for Filling Out Periodic Reports
Based on Articles 15 and 19-2 of the Act on the Rational Use of Energy.
For other types of energy, calculations were performed using the caloric values listed in the revised Act on Promotionof Global Warning Countermeasures (an enforcement ordinance published March 31, 2010 by the Ministry of theEnvironment and the Ministry of Economy, Trade and Industry).

Environmental performance indicator

Basis for calculation

Greenhouse gas emissions (10 kt-CO 2 equivalent)Greenhouse gas emissions from electric power consumption, fuel consumption and combustion, waste incineration,and from emissions to the atmosphere of HFC, PFC, and SF6 are calculated for city gas according to the caloric andemission values in Appendix 4, “List of City Gas Suppliers and Supplied Quantity of Heat” (revised April 15, 2013) of theRequirements for Filling Out Periodic Reports Based on Articles 15 and 19-2 of the Act on the Rational Use of Energy.
For other forms of energy, calculations were made using caloric and emissions values listed in the revised Act onPromotion of Global Warning Countermeasures (an enforcement ordinance published March 31, 2010 by the Ministry ofthe Environment and the Ministry of Economy, Trade and Industry).
Note however that electricity emission factors from electricity consumption for the past year were calculated using theFederation of Electric Power Companies of Japan’s 2005 emissions unit as detailed on page 20.
Emissions for offshore sites were calculated using factors drawn from sources such as the Greenhouse Gas Protocol
and the U.S. Department of Energy.

SOx emissions (tons)

Calculated based on emissions volume per unit time and duration of operation
Sulfur oxide (Nm3/h) × annual hours of facility operation (h) × 64/22.4 × 10 -3

NOx emissions (tons)

Calculated using the formula for NOx emissions in the calculation graph from the “Environmental Activity Evaluation
Program,” Ministry of the Environment, 1999

Dichloromethane (tons)

Total emissions to the atmosphere from plants handling at least 1 ton annually

Chlorofluorocarbons (tons)

Total emissions to the atmosphere from plants handling at least 1 ton annually

Dioxins and dioxin-like compounds (mg-TEQ)

Total emissions to the atmosphere from incineration in own furnaces

VOC emissions (tons)

Annual use by individual production plant of chemical substances subject to the PRTR Law reporting is the amountexceeding the exemption cutoff. For other VOCs, the figure shown is the total of VOCs amounting to 1 ton or more ofemission to the atmosphere.

Water discharged

Annual emissions to public waters and sewer systems

COD emissions (t)Calculated from annual discharged water and average concentration to which the Water Pollution Control Act applies.
COD concentration (mg/l) × annual designated water discharge (m3) × 10 -6

Nitrogen emissions (tons)

Calculated from annual discharged water and average concentration to which the Water Pollution Control Act applies.
Nitrogen (mg/l) × annual designated water discharge (m3) × 10 -6

Phosphorous emissions (tons)

Calculated from annual discharged water and average concentration to which the Water Pollution Control Act applies.
Phosphorus concentration (mg/l) × annual designated water discharge (m3) × 10 -6

Undesired materials generated (kt)

Total of valuable substances sold and outsourced processing

Waste emissions (kt)

Total outsourced waste processing

Waste per unit of production (tons/10 million yen)Calculated from waste emissions and DNP consolidated sales
Domestic figures calculated based on domestic sales

Landfill waste (kt)Of outsourced waste processing, the total disposed of in landfills after direct or indirect processing

Recycle rate (%)

For paper, plastic, metal, and glass, calculated as: (amount of valuable materials + amount of materials recycled asresources + volume of thermal recycling) / undesired materials production volume

Zero emissions

Calculated as final disposal volume / undesired materials production volume, and defined as less than 0.5%

Used paper segregation/collection (t)Office paper collectedGreenhouse gas emissions (10 kt-CO 2 equivalent)

Calculated in conformance with greenhouse gas emission calculation methods in “General Guidelines on Supply Chain
GHG Emission Accounting, Ver 1.0” published by the Ministry of Economy, Trade and Industry and the Ministry of theEnvironment2
