Class 3 and Class 4 chemical substances for which the amount handled annually is 100kg (Class3) /1,000kg (Class4) or more are subject to reporting.

• The volume of chemical substances used at sites; purchase volume is substituted when exact volume of usage cannot be determined.
• Volume of chemical substances released from sites in relation to their operation; calculations are based on purchase volume x distribution coefficient.

Concentrations in water discharged x volume of water discharged. Sites that are requested to measure by law and other requirements, such as contracts, etc., are subjected to this data collection.

Emissions of Air Pollutants (NOx, SOx)

Volume calculated by multiplying emission volume by emission concentration. Sites that are requested to measure by law and by other requirements, such as contracts, etc., are subjected to this data collection.
