National Pollutant Inventory (NPI)
The National Pollutant Inventory (NPI) database collects information about emissions and transfers of 93 substances across Australia.
If your industrial facility exceeds reporting thresholds for one or more substances you are required to calculate and report the annual emissions and transfers that result from its operations. There is a maximum penalty of $2,000 if your business fails to comply with NPI reporting requirements.
You can also search the NPI database to find out about emissions in different areas, and details of individual facilities reporting to the NPI.
Reporting to the NPI
Use the NPI guide to determine if your facility exceeds NPI reporting thresholds and will need to report to the NPI.
If your facility is required to report, estimate the emissions of NPI substances which have exceeded thresholds to air, land and water.
If your facility needs to report transfers of NPI substances in waste, estimate the amount contained within the waste. Use the industry reporting materials and your industry's emission estimation technique manual to help you estimate emissions and transfers.
Read the Environmental Protection Regulation 2019 for more on NPI reporting requirements in Queensland.
