*1 VOCs comprise the six VOCs that are most prevalent in emissions from the Kubota Group: xylene, toluene, ethylbenzene, styrene, 1,2,4-trimethylbenzene and 1,3,5-trimethylbenzene.

*2 Previously, the sulfur contained in the slag and particulate matter was included in the calculation of SOx emissions emitted from the fuel combustion in casting plants. However, from RY2014, it has been excluded from calculations as it is not emitted into the atmosphere.

*3 Starting from RY2016, calculation of the amount of atmospheric discharge (SOx, NOx, soot and dust) targets only the soot and smoke generating facilities defined in the Air Pollution Control Act. Accordingly, the figures for RY2012 through RY2015 are modified.

*4 Data for total discharge from business sites subject to total emission control.
