Greenhouse Gases

CO2 For CO2 conversion, the fixed value is the 2007 receiving end coefficient of the Japan Auto Parts Industries Association (JAPIA).
Calculations of HFCs, SF6 and CO2 employ global warming figures prescribed by the Law Concerning the Promotion of Measures to Cope with Global Warming enforcement regulations.

CO2 Emissions by Scope

CO2 Emissions by Scop

Note: Of the “scopes” (scope of emissions) for greenhouse gases (GHG): (a) Scope 1 emissions are direct GHG emissions from the entity such as gasoline or the combustion of heavy oil; (b) Scope 2 emissions are indirect GHG emissions resulting from the consumption of energy purchased; and (c) Scope 3 emissions include indirect GHG emissions from related activities undertaken outside of the entity such as raw materials procurement, production, disposal and logistics.

Emissions Data by Plants

Water Quality

*Units: PH…none, Escherichia coli…colony forming units/cc, { }… average per day, ―… not established, ND… below detection limit

*Regulatory values represent the strictest values specified in environmental laws and regulations, ordinances and agreements.

*When measurement is conducted only once, the value is presented under "Maximum."

*The following regulatory items were below the lower quantitative limit at all plants (not detected):All chromes, copper, all cyanides, hexavalent chromium, cadmium, lead, all mercuries, alkyl mercury, arsenic, organic phosphorus, PCB, trichloroethylene, tetrachloroethylene, dichloromethane, carbon tetrachloride, 1,2-dichloroethane, 1,1-dichloroethylene, cis-1,2-dichloroethylene, 1,1,1-trichloroethane, 1,1,2-trichloroethane, 1,3-dichloropropene, 1,4-dioxane, thiuram, simazine, thiobencarb, benzene, selenium

Air

Units: Dust (g/Nm3), NOx (ppm), SOx (K value), hydrogen chloride (mg/Nm3), dioxin (ng-TEQ/Nm3)
