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).

–Nitrogen emissions (tons)

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

COD emissions (tons)

Chloroﬂuorocarbons (tons)

VOC emissions (tons)

Waste emissions

Greenhouse gas emissions from electric power consumption, fuel consumption and combustion, wasteincineration, 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 Quantityof Heat” (revised April 15, 2013) of the Requirements for Filling Out Periodic Reports Based on Articles 15 and19-2 of the Act on the Rational Use of Energy. For other forms of energy, calculations were made using caloricand emissions values listed in the revised Act on Promotion of Global Warning Countermeasures (anenforcement ordinance published March 31, 2010 by the Ministry of the Environment and the Ministry ofEconomy, Trade and 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.
