Each year, more than 4 000 industrial facilities estimate their emissions and waste transfers of toxic substances and report them to the NPI. Now in its 22nd year, the NPI helps communities, governments and researchers understand and monitor the sources of industrial pollution and waste and helps identify priorities for decision making.
The NPI estimates emissions for 93 toxic substances and provides the source and location of these emissions around Australia:
The NPI is a shared program between the Australian Government and state and territory governments. Data is collected from facilities by state and territory agencies and this data is collated and published on the NPI website.
