Latest NPI emission data - 2007-08

The National Pollutant Inventory (NPI) is a publicly accessible database with information on the types and amounts of substance emissions to the Australian environment.

Every year Australian industrial facilities that exceed the specified thresholds of the 93 NPI substances calculate and report their emissions to air, land and water. The NPI also holds some data for diffuse sources whose emissions are aggregated together, including emissions from motor vehicles. Diffuse data are not collected annually and may be from varying years.

Facility data were published on the NPI web site on 31 March 2009.
This was the tenth NPI reporting year.
Facilities reported on 87 of the 93 NPI substances from 4116 facilities.
49 of the 87 NPI substances reported by facilities showed a decrease compared to the previous year.
The data set includes new information as a result of the 2007 variation to the NPI National Environment Protection Measure .

Using the NPI emission data

Adding together emissions of different substances does not provide a measure of total pollution. This is because NPI substances have different properties and toxicities. A small emission of a highly toxic substance may be more significant than a large emission of a far less toxic material.

The disclaimer has further information about using NPI data.

Pollution control is the responsibility of state and territory governments.
