Australian industrial facilities using more than a specified amount of any substance listed on the National Pollutant Inventory (NPI) reporting list are required to estimate and report emissions of these substances annually. For example, in Tasmania there were 63 Tasmanian facilities reporting emissions of carbon monoxide in 2002.
Reporting facilities in the Mersey-Lyell Region estimated the greatest volume of emissions of lead and compounds, oxides of nitrogen and particulate matter. The Northern Region estimated the highest volume of emissions of carbon monoxide, sulfur dioxide and total volatile organic compounds. The Greater Hobart and Southern Region estimated the largest emissions of mercury and compounds.

- nil or rounded to zero.
(a) Specified Tasmanian reporting facilities data was obtained from the facility emission data report (air) within http://www.npi.gov.au at July 3, 2003.
(b) Data are derived using best estimate methodologies, not direct measurement. Accuracy of data will vary according to the estimation technique used. Estimates accessed at July 3, 2003.
(c) Data for 12-month reporting period ending 30/06/2002. Data collected from 2002 onwards will provide a more valid comparison due to the refinement of estimation techniques.
(d) Estimates have been rounded and minor discrepancies may occur between sums of component items and totals.
(e) Dust particles of any substance that are less than 10 micrometres diameter were recorded.
(f) A grouping of a wide range of volatile organic chemical compounds (substances made up of predominantly carbon and hydrogen) to simplify reporting when these are present in ambient air or emissions.
