About the Report
The NPI is an Internet database designed to provide the Australian community, industry and government with information on the types and amounts of certain substances being emitted to the air, land and water around Australia.
The second year of the NPI saw the number of facilities reporting to it increase by over 50 percent, the number of sectors covered by it increase by over 300 percent, and the average number of substances reported by each facility increase by almost 50 percent.
In addition, a large number of aggregated emission data studies, both airsheds and water catchments, have been completed and included on the database. These studies provide a more complete picture of pollutant emissions in Australia.
NPI data can be used for promoting cleaner production and pollution prevention and identifying sources of environmental pressures. This report provides a summary of the second year NPI data. For more information on 1999-2000 emissions please visit the NPI Internet site at http://www.npi.gov.au/index.html
This summary report is based on the NPI data published on 28 May 2001. It is important to realise that the NPI is a database of estimated emissions and the accuracy of the data will vary according to the estimation technique used.
Aggregated emissions data is not estimated every year, but for a particular period to provide a snap-shot of the background emissions from mobile and non-industrial sources and sub-threshold facilities (smaller facilities whose emissions are below certain levels). Comparative analysis of the aggregated emissions data is likely to be misleading, because at this early stage of implementation of the NPI the techniques used are not consistent across all the jurisdictions. It would also be unwise to make comparisons between industries or facilities without first checking to ascertain the basis and extent of reporting. Some reporting facilities have included Internet links to their own pages in their Internet reports. The views expressed in the pages reached through the facility hotlinks are not necessarily the views of the Commonwealth, Environment Australia or the National Environment Protection Council.
