Annual use by individual production plant of chemical substances subject to the PRTR Law reporting is theamount exceeding the exemption cutoff. For other VOCs, the figure shown is the total of VOCs amounting to
1 ton or more of emission to the atmosphere.
Annual emissions to public waters and sewer systems
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
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
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, outsourced processing and amount sent to own processing facilities

Waste emissions (kt)

Total outsourced waste processing

Waste per unit of production(tons/billion yen)Calculated from waste emissions and DNP consolidated sales

Final disposal volume (kt)
Final disposal rate (%)

Waste Management and Public CleansingAct

Of outsourced waste processing, the total disposed of in landfills after direct or indirect processing
Final disposal volume ÷ undesired materials production volume

Recycle rate (%)

For paper, plastic, metal, and glass, calculated as: (amount of valuable materials + amount of materials
recycled as resources + 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 (tons)

Scope 3Calculated for equipment using liquid fuel (fuel oil or kerosene), based on emission volume per unit of time andhours of operation
Sulfur oxides (Nm3/h) × annual hours of facility operation (h) × 64/22.4 × 10 -3

Dichloromethane (tons)

VOC emissions (tons)

Waste emissions

Domestic:	GHG emissions due to electricity use, fuel use/combustion, burning of waste and atmosphericemissions of HFCs/PFCs/SF6/NF3 are calculated based on the Manual for Calculating andReporting Greenhouse Gas Emissions, Ver.4.3.2 (June 2018). For electricity emission factors inFY2018, the emission factor for each electric power company is used at manufacturing sites basedon the emission factor for each electric power utility (FY2017 results) (announced on December 27,2018) and a common emission factor is used for offices and the Bookstore Group.
Overseas:	the emission factor for each country is used based on GHG Protocol (Ver1.0 of Compilation ofemission factors used in the cross-sector tools) of 2006.

Calculated using the formula for NOx emissions in the calculation graph from the “Environmental Activity

2005 Edition

Sum of depreciation, repair, operating and other costs of environmental facilities, environmental survey costand personnel cost for the fiscal year
Cost of personnel conducting administration activities is calculated by applying 100% of the average
personnel cost for those engaging in the activities full-time. For those also assuming other roles, 10 or 20% of
the average personnel cost will be applied, depending on their assignments.

Consumption/emissions per unit ofdomestic sales

Environmental Accounting Guidelines,
2005 Edition

Consumption per unit of consolidated sales in Japan used as a performance indicator for resources input intobusiness activities (energy and water), and emissions per unit of consolidated sales in Japan as a performanceindicator for waste and CO2 emissions

Disposal cost saving–

Calculated by using a formula: (Per-unit volume for the base period – per-unit volume for the current period) x
volume of business activities for the current period
Volume of business activities is represented by consolidated sales in Japan, while per-unit volume iscalculated by using a formula: waste disposal cost/consolidated sales in Japan. Per-unit volume for the baseperiod (previous fiscal year) is the aggregated average of the past three years from the previous fiscal year.
