National Pollutant Inventory (NPI)
The National Pollutant Inventory (NPI) is a database established to provide the community, industry and government with information on substances being emitted to the air, land and water, and transported in waste. The inventory tracks the magnitude of emissions and the amounts transported in waste of 93 substances. EPA has the responsibility for implementing the NPI program in Victoria.
