National Pollutant Release Inventory
The National Pollutant Release Inventory (NPRI) is Canada’s public inventory of releases, disposals and transfers. It tracks over 300 pollutants from over 7,000 facilities across Canada.
Preliminary NPRI Data is now available for 2023. Preliminary data is available through the NPRI Dashboard and NPRI data search. Reviewed data for previous years is available on our Explore Data page.
