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 ofCity 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 onPromotion of Global Warning Countermeasures (an enforcement ordinance published March 31, 2010 by theMinistry of the Environment and the Ministry of Economy, Trade and Industry).

Chlorofluorocarbons (tons)

VOC emissions (tons)

Waste emissions

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 and emission 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 ofthe Act on the Rational Use of Energy. For other forms of energy, calculations were made using caloric andemissions values listed in the revised Act on Promotion of Global Warning Countermeasures (an enforcement
ordinance published March 31, 2010 by the Ministry of the Environment and the Ministry of Economy, Tradeand Industry).
Note however that electricity emission factors from electricity consumption for the past year were calculatedusing the Federation 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.

Dichloromethane (tons)

Dioxins and dioxin-like compounds (mg-TEQ)

Emissions to waters

Calculation method, etc.

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 -6Calculated 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 processingWaste per unit of production(tons/billion yen)Calculated from waste emissions and DNP consolidated sales
Domestic figures calculated based on domestic sales

Final disposal volume (kt)Waste Management and Public Cleansing
ActOf outsourced waste processing, the total disposed of in landfills after direct or indirect processing

Final disposal rate (%)

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%
