Latest NPI emission data - 2006-07

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

Emissions to air, land and water are estimated by facilities each year. The NPI also holds some data for diffuse sources whose emissions are aggregated together, including emissions from motor vehicles.

Facility data was published on the NPI web site on 31 March 2008.
This was the ninth NPI reporting year.
Since reporting started in 1999, the number of facilities reporting to the NPI has trebled.
Facilities reported on 86 of the 90 NPI substances from 3951 facilities.
47 of the 86 NPI substances reported by facilities showed a decrease compared to the previous year.
New airshed data is now available for "Greater Sydney Newcastle & Wollongong Regions (GMR)" airshed. This airshed replaces the old "Sydney Newcastle Wollongong" airshed.
All industry sector codes have been updated to Australian and New Zealand Standard Industrial Classification (ANZSIC), 2006.

Using the NPI emissions 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 one highly toxic substance may be more important 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 states and territories.

NPI Conference - 10 years of NPI: tracking pollution across Australia

In 2008, the NPI will hold 10 years of data on the emission of substances from industrial and non-industrial sources across Australia. Now, more than ever, a data set of this size can be critical in supporting informed decision making processes at an environmental and economic level.

Underpinning the 10 years of NPI data are various themes:

Reporting and compliance - emission estimation and legal instruments
Driving cleaner production - what industry is doing to reduce emissions and waste
Using NPI data - who uses NPI data and for what purpose

Find out more about the NPI conference on 22 and 23 May 2008.
